Origin of pneumatic ball valve

Wuxi Xinming automatic control valve industry co., ltd. and you to understand the origin of pneumatic ball valve Pneumatic ball valve is a ball valve with pneumatic actuators, and pneumatic ball valve is evolved from the globe valve. The lifting action has the same rotation of 90 degrees, except that the cock body is a sphere, which has a passage through hole or round through its axis. The ratio of the spherical surface to the channel opening should be such that when the ball rotates 90 degrees, the spherical surface should appear at the inlet and outlet, thus cutting off its flow. The working principle of the pneumatic ball valve is to rely on the rotary valve so that the valve is blocked or dredged. The pneumatic ball valve switch is light and small in size, which can be made into a large caliber, simple in structure, reliable in sealing, and convenient in maintenance. The sealing surface and the spherical surface are often in a closed state and are not easily eroded by the medium, so it can be used in various industries. Widely used. Pneumatic ball valves are now widely used in petroleum, chemical, power generation, papermaking, atomic energy, aviation, rockets and other departments, as well as in people's daily lives. Pneumatic ball valve and plug valve is a type of valve, but its closure is a sphere, the sphere around the center line of the valve body to rotate to reach the closed, open a valve. Quick and convenient 1. switch can meet the requirements of quick opening and quick closing of high-altitude tunnel for pipeline 2. the fluid resistance is small, so whether it is full-bore type reduced diameter ball valve is a smaller fluid resistance in all valves. 3. firm valve seat seal, general ball sealing ring are made of tetrafluoroethylene type other polymer materials with better plasticity. where there are higher requirements for sealing, soft sealing is easier to ensure sealing. metal sealing, <hard seal> structure can withstand high pressures of 10Npa, 16Npa and 32Npa at 350 ℃ in daily life. 4. solid valve stem seal, stem reverse sealing structure can be larger with the progress of the medium, valve stem valve opening and closing only for rotation movement, and do not do lifting movement. The sealing packing of the valve stem is not easily damaged. The sealing life of the valve stem is greatly extended. 5. of the long service life, the pneumatic device is more than 60000 in the damage test. Because the sealing part of the ball valve is mostly made of polytetrafluoroethylene with good self-lubricating properties, such as polytetrafluoroethylene, which is made of less conflict and wear with the ball valve and the valve stem, ensuring the service life of the valve. The above is the origin of the pneumatic ball valve shared by Wuxi Xinming automatic control valve industry co., ltd. and you.

Fault and Protection Management Method of Pneumatic Actuator System

Wuxi Xinming automatic control valve industry Co., Ltd. introduces the fault and protection management methods of pneumatic actuator system Pneumatic actuator is driven by air pressure to open and close or adjust the valve actuator, generally shallow called pneumatic head. Zhejiang Shuangzhong Automatic Control Valve Co., Ltd. has various technical requirements for pneumatic heads. The characteristics of pneumatic actuators are compact double piston gears, rack-type structure, accurate meshing, high efficiency and constant output torque. When compressed air enters the pneumatic actuator from the nozzle, the gas pushes the double piston to move linearly to the two ends (cylinder head end). The rack on the piston drives the gear on the rotating shaft to roll 90 degrees counterclockwise, and the valve is opened. At this moment, the gas at both ends of the pneumatic actuator valve is discharged with the B nozzle. Conversely, when compressed air enters the two ends of the pneumatic actuator from the B official nozzle, the gas pushes the double plug to move linearly to the center, and the rack on the piston drives the gear on the rotating shaft to roll 90 degrees clockwise, and the valve is closed. At this moment, the gas in the center of the pneumatic actuator is discharged with the nozzle A. According to requirements, pneumatic actuators can be installed with the opposite transmission principle of the standard type. The actuator is an indispensable structure in the process of industrial production automation. It has high frequency of use and is simply caused by high temperature, high pressure and serious social and environmental problems, resulting in the need for repair. Actuator power includes electric, pneumatic and hydraulic, but here mainly introduces the pneumatic actuator system fault and protection management methods, the analysis results are as follows Pneumatic actuator faults include clogging, leaking, and control coil burning. Here, we will briefly analyze the problems presented in the repair method based on these three basic conditions. The pneumatic actuator is stuck. Disassemble the actuator to see if it sticks, dissect and assemble from scratch. Check whether the pneumatic actuator leaks, the valve stem leaks, check whether the sealing sleeve is damaged, and replace it in time if it is damaged. Damage to the seal causes leakage. Check the piston or check for impurities. The piston ring and smooth parts can be replaced. There is also the problem of aging and metamorphosis of the coil, so it can be judged with a multimeter after energization.

Buy pneumatic ball valve is the need to pay attention to what problems?

Wuxi Xinming automatic control valve industry co., ltd. now shows you what problems you need to pay attention to when purchasing pneumatic ball valves. In industrial activities, the use of valves can be a good control of the development of industrial activities, and can ensure the safety of personnel and enterprise material savings, especially the pneumatic ball valve, through the deployment of various other accessories, can complete a lot of risk and even high-altitude work, to ensure the safety of people's lives and production. So high-quality pneumatic ball valve in the purchase of the time should pay attention to what the problem? Below, let us take a look at it. 1. Price is one of the factors that demand refers When purchasing pneumatic ball valves, in addition to the above two aspects, the price of pneumatic ball valves should also be considered. I am afraid that too low a price cannot guarantee the quality, because the production of any valve requires capital. The so-called "a penny for a penny", assuming that the price is too low, even the capital cannot be guaranteed, then the quality problem is also worrying. 2, the selection of good quality pneumatic ball valve If you want to buy the pneumatic ball valve can operate well and ensure the operation function, then your selection is very important. Buyers can first understand and compare some valve brands at home and abroad, which can be useful to prevent the purchase of fake and inferior products from small manufacturers, and can also check the credibility of the selection of pneumatic ball valve, which can provide outstanding quality assurance.

How to increase the switching speed of pneumatic actuators?

How to increase the switching speed of pneumatic actuators?

How to increase the switching speed of pneumatic actuators? Wuxi Xinming automatic control valve industry Co., Ltd. will give you a detailed explanation Pneumatic actuator is a kind of pneumatic actuator that makes continuous rotary motion. It is an energy conversion device that converts the pressure energy of compressed air into reverse mechanical energy. Its effect is equivalent to an electric motor or hydraulic motor. It outputs torque and drives execution. The organization makes a rotary motion. Gear type pneumatic motor, vane type and piston type are widely used in pneumatic transmission. Pneumatic actuator is a prime mover with compressed air as the working medium. It uses the expansion of compressed gas to convert pressure energy into mechanical energy. It is also commonly called a pneumatic motor. Although various types of pneumatic actuators have different structures and working principles, most pneumatic actuators have the following characteristics: Can be stepless speed regulation. As long as the opening of the intake valve or exhaust valve is controlled, that is, the flow of compressed air is controlled, the output power and speed of the motor can be adjusted to achieve the purpose of adjusting the speed and power. It can turn forward or reverse. Most pneumatic actuators can realize the forward and reverse of the output shaft of the gas motor, and can be reversed instantaneously. In the forward and reverse conversion, the impact is very small. There is a regulating valve on the pneumatic actuator. You can see if it has been opened to the maximum. If so, you can also consider adding signal air source pressure or pipe diameter within a certain range. Also increase the air source pressure and the size of the air source pipe, increase the corresponding cylinder hole, and then add a quick exhaust valve, which will increase his opening speed. In fact, when selecting pneumatic actuators for valves, the switching time requirements of valves should be considered. Pay attention to the air opening and closing torque and pressure opening and closing torque of valves. Under the premise of considering the safety factor of torque, consider the air intake and exhaust speed of pneumatic actuators, and consider increasing the pipe diameter and matching of pneumatic control valves and quick discharge valves on exhaust pipes and pneumatic accessories! Pneumatic actuators are sometimes equipped with corresponding auxiliary equipment. Commonly used valve positioner and handwheel organization. The effect of the valve positioner is to use the feedback principle to improve the performance of the actuator, so that the actuator can be controlled by the controller signal to achieve accurate positioning. The effect of the handwheel organization is that when the control system is due to power failure, gas failure, no output of the controller or failure of the execution organization, it can be used to directly operate the control valve to maintain the normal production. The above is about how to increase the switching speed of pneumatic actuators.

Pneumatic ball valve selection key, how should the correct selection?

Pneumatic ball valve selection key, how should the correct selection?

The key to the selection of pneumatic ball valve, how should it be correctly selected? Wuxi Xinming automatic control valve industry Co., Ltd. today for you to introduce in detail Pneumatic ball valve is widely used in chemical, petrochemical and other occupations. Pneumatic ball valve is the use of piston cylinder to drive the ball valve, with solenoid valve, limit switch box, filter valve and other accessories, you can complete the active control. Pneumatic ball valve is generally used to do rapid blocking, its outstanding sealing function and rapid blocking speed, is not replaced by other valves. There are also equipped with an electric valve positioner, which is made into a pneumatic adjustment ball valve to adjust the flow rate or pressure of the medium. Pneumatic ball valves can be divided into single-effect and double-effect according to the form of cylinders. Double-effect pneumatic ball valve switches all require air sources, while single-effect pneumatic ball valves require air sources when opening or closing. Once the air source is faulty or the solenoid valve is faulty, the valve will be actively reset due to the effect of springs. For those working conditions that require valves to be actively reset under certain circumstances, single-effect pneumatic ball valves need to be selected. Pneumatic ball valve body can be so combined, but also so the whole. It has the same rotation as the plug valve, but the difference is that the plug body is a sphere with a channel through its axis or a circular through hole. The share of the spherical surface and the channel opening is that when the ball rotates 90 degrees, the spherical surface should be fully presented at the inlet and outlet, and then the activity should be blocked. There are many types of pneumatic ball valves, including pneumatic flange ball valve, pneumatic threaded ball valve, pneumatic ultra-thin ball valve, pneumatic O-type ball valve, pneumatic V-type ball valve, pneumatic three-way ball valve, pneumatic four-way ball valve, pneumatic sanitary ball valve, pneumatic vacuum ball valve, pneumatic insulation ball valve, pneumatic fluorine ball valve, etc. Pneumatic O-type ball valve is suitable for two-position blocking, pneumatic V-type ball valve is suitable for adjustment, and is generally used for active control of pulp and other media by papermaking profession. Pneumatic three-way ball valve and four-way ball valve are used for reversing media, while pneumatic sanitary ball valve is suitable for food, pharmacy and other occasions with high hygiene requirements. Pneumatic fluorine-lined ball valve is suitable for corrosive media, and pneumatic insulation ball valve is suitable for media that may solidify at normal temperature, such as asphalt.
