Three-electric high-pressure valve dimensions I. Product Overview: ???? Q947H electric fixed ball valve is a new generation of high-performance ball on 海佩林 produced, suitable for long distance pipelines and industrial pipelines generally, its strength, safety, resistance to harsh environment, etc. were designed special consideration for a variety of corrosive and non-corrosive media. Compare it with from the float valve, when the job, force the valve before the fluid pressure on the ball all happening transfer to the bearing, does not make the ball move to the seat, so the seat will not accept too much pressure, so mounted ball valves The torque is small, seat deformation, stable sealing function, use long life, suitable for high pressure, large diameter occasions. Leading pre-stretched spring seat assembly having a self-tightening properties and achieve upstream sealing. Each valve has two development each direction can be sealed. Therefore it means no flow constraint is bidirectional. Pneumatic valve has two fixed formula and three type two body structure, the flange bolts convergence, the choice of PTFE sealing insert stainless steel circle, rims without damaging the rear springs to ensure that the seat close to the ball adhere sealed. Upper and lower stems are no PTFE bearings, reducing friction and effortless operation, no tabs at the bottom of a small shaft, ball and seals to ensure the access of the orientation. Full Bore: valve flow aperture and tubing used together for pipeline cleaning. Second, the principle: ?? Q947H electric fixed ball is suitable for two to intercept conditioning applications. Cohesion selection valve and actuator direct connection, the electric actuator servo system built without reprovision servo amplifier 4-20mA input signal and 220VAC power to control the work. Having a connection simple, compact structure, small size, light weight, low resistance, reliable operation of secure other advantages. Electric valve actuators can be fixed according to user needs other equipment UNIC, PSQ, HQ, DHL and other types of electronic electric actuators or GTX, AL, such as gas piston actuator. Second, the commodity structure, usefulness, two-piece and three-????? fixed measurement device known as split ball valve, the valve body along a straight axis of the valve channel cross-section is divided into two halves asymmetric mercy, It is mainly used to intercept in the pipeline, distribution and change the direction of media activities. Electric fixed ball pivot its construction ensures accurate ball bearing. Electric fixed valve seat selection specification stretched spring construction, the valve cover to the ball, to ensure a good low pressure sealing function. Before the ball valve, the valve seat can be sealed? The so-called two-way sealing characteristics, use its own drain valve body cavity can be discharged outside. Pivot selection Blowout maintenance structure, low coefficient of friction bearings. Electric fixed ball has excellent function, reliable high, widespread use, reasonable price and other advantages.
