Pneumatic valves are suitable for operation under what temperature conditions. The use and characteristics of pneumatic valves. The use and characteristics of pneumatic valves are right-angle rotary structures, which are used in conjunction with valve positioners and can complete proportional scheduling. V-shaped valve core is suitable for various scheduling occasions, with large rated flow coefficient, large adjustable ratio, good sealing effect, flexible scheduling performance, small volume and vertical lying equipment. Suitable for controlling gas, steam, liquid and other media. It is characterized by a right-angle rotary structure, which is composed of V-shaped valve body, pneumatic actuator arrangement, positioner and other accessories. It has an inherent flow characteristic of approximately equal to 100 ratio. Double bearing structure, small starting torque, good activity and induction speed; Strong shearing ability.
Pneumatic piston execution arrangement compressed air as a power source, through the movement of the piston to drive the crank arm for 90 degrees rotation, to make the valve active opening and closing. Its components are: scheduling bolts, execution arrangement box, crank arm, cylinder block, cylinder shaft, piston, connecting rod, universal shaft. Operating principle of pneumatic valves: Pneumatic scheduling valves consist of execution arrangements and scheduling arrangements. The execution arrangement is the thrust component of the scheduling valve, which causes the corresponding thrust according to the size of the control signal pressure to advance the scheduling action. The valve body is the scheduling component of the pneumatic scheduling valve, which is directly in contact with the scheduling medium to schedule the flow of the fluid. Pneumatic valve is to use compressed air as the power source, the cylinder as the actuator, and with the help of electric valve positioner, converter, solenoid valve, holding valve and other accessories to drive the valve, complete the switching value or proportional scheduling, receive the control signal of the industrial active control system to complete the scheduling of various process parameters such as flow rate, pressure, temperature and the like of the pipeline medium. Therefore, it is necessary to strengthen the repair of pneumatic dispatching valve.
Pneumatic valvePrecautions for temperature environment. At present, the temperature changes in many manufacturers are relatively large. When using pneumatic dispatching valves, equipment should take into account the temperature in the environment. Assuming that the temperature in the environment is not appropriate, the operation condition of the air conditioning valve will be affected. So what temperature condition is the pneumatic valve suitable for operation. When the equipment uses the pneumatic dispatching valve, the user needs to pay attention to the fact that the indoor ambient temperature cannot pass minus 30 degrees and the Z height cannot pass 60 degrees. Assuming that the equipment passes this temperature range, it is easy to fail. In addition, the humidity of the indoor environment must also meet the requirements. The humidity cannot be too 95%. Assuming that the changes in temperature and humidity in the workplace are rugged, the user can control the temperature and humidity of the indoor equipment by flashing instruments, so that the air conditioning valve can operate under appropriate conditions.
