Wuxi Xinming automatic control valve industry to introduce usPneumatic ball valveThe type of preparation indicates which regulations the approach needs to adhere.
Pneumatic ball valve ball is changed from the plug valve, its center of the ball is 90 degrees of rotation of the action, the ball around the center line of the valve body to rotate to reach the open, a circular through hole or channel through its axis. When the ball center rotates to 90 degrees, the valve is in a tightly closed state. When the actuator is working, the valve can be tightly closed with a small rolling torque, so that the working principle of rapid truncation and blocking can be achieved.
       Pneumatic ball valveThe main application in the rapid blocking, distribution and change of media in the activities of the pipeline. Pneumatic ball valve it open and close agile, suitable for the use of fine caliber. V-sphere can be used to accurately adjust the media flow. Pneumatic ball valve structure has two kinds of difference, one is the O-type ball core, O-type ball valve core for floating type careful casting, flow channel mouth and pipe diameter is the same, mainly used as a cut-off switch. The other is a V-shaped ball core, which uses a fixed structure, the ball core with a V-shaped cut off, the actuator is equipped with a locator to achieve the fiber, granular medium ratio adjustment.
Any section of the pneumatic pipeline ball valve can be arranged at the upstream end, and the handle pneumatic pipeline ball valve can be arranged at any position of the pipeline. If the pneumatic pipeline ball valve is equipped with an actuator (such as a gear box and an electro-pneumatic actuator), a vertical device is required, and the valve inlet and outlet are in a horizontal position. Sealing gasket shall be installed between ball valve flange of pneumatic pipeline and pipeline flange according to pipeline design requirements. The bolts on the flange shall be tightened symmetrically, successively and evenly. If the pneumatic pipeline ball valve adopts pneumatic, electric and other actuators, according to the instructions to complete the gas source, power supply device.
Additional code of ball valve: V represents open valve core with V-shaped structure, D represents open low temperature, B represents heat preservation, P represents partial pain structure, U, S and DY represent top-mounted type. Ball valve name code, q represents ball valve; Ball valve drive code, 2 represents electro-hydraulic, 3 represents turbine, 6 represents pneumatic, 7 represents hydraulic, 9 represents electric and manual without code; Codes of connection mode, one represents internal thread, four represents flange type, six represents welding, and seven represents wafer type; structural type code, floating type, one represents straight flow channel, two represents Y-type tee, four represents L-type tee, and five represents T-type tee; fixed type, zero represents hemisphere straight, six represents four-way flow channel, seven represents straight flow, eight represents L-type tee, and nine represents Y-type tee;
Sealing material code, B babbitt alloy, F fluorine rubber, F46 fluorine lining, H rust steel, J rubber lining, M monel alloy, N nylon plastic, monel P, Y hard alloy, W valve body direct processing; The pressure grade represents that 16 indicates that the pressure is 16kg (1.6Mpa) and can reach 64Mpa to a large extent. 150LB indicates the us standard pound pressure, the large pressure resistance grade can reach 2500LB(150LB = 1.6MPa/300LB = 2.5-4.0MPa/400LB = 6.4MPa/600LB = 10MPa);5K indicates daily pressure and high pressure 63K; Valve body material code, A titanium and titanium alloy, C carbon steel, I chromium molybdenum steel, P18-8 stainless steel, RMo2Ti stainless steel, S plastic.
The above is Wuxi Xinming automatic control valve industry to introduce us to the relevant content.
