GQ47H track pneumatic ball valve is introduced

domestic currently used O type pneumatic ball valve are all under a given pre-tightening force ball core friction with the pneumatic valve seat to open and close, often cause the sealing surface is damaged, pneumatic valve leakage and stuck phenomenon, GQH track pneumatic ball valve is the updated design makes the ball against the common defects core rotation to switch is a new type of pneumatic ball valve, pneumatic valve can make the ball no friction, achieve the aim of safety without leakage, and greatly improves the service life of pneumatic valve.
orbit pneumatic ball valve product features: - Hong feng track pneumatic ball valve
, single pneumatic valve seat design. Eliminates the pneumatic valve lumen medium because of abnormal pressure and problems affecting the safety of use.
and low torque design. Special structure design of the pneumatic valve stem, only with a small hand wheel pneumatic valve can easy opening and closing.
, opening and closing without friction. This function completely solve the traditional pneumatic valves for sealing surface friction each other and affect the sealing problem.
, the jacket type structure. The pneumatic valve can be directly mounted on the pipeline on-line inspection and maintenance. Can effectively reduce the parking device, reduce the production cost.
track ball working principle of the pneumatic valve: - Hong feng orbit ball pneumatic valve is introduced
(1) when the pneumatic valve is in full open position, turn the handwheel clockwise, the pneumatic stem nut and cooperated by thrust bearing, pneumatic valve rod began to drop and drive the ball begin to spin.
(2) the continuous rotation handwheel, pneumatic valve stem of the precision of spiral curve groove track, interact with embedded in its guide pin, drive the ball with the pneumatic valve stem clockwise rotation.
(3) when the pneumatic valve will be closed, pneumatic valve rod drives the ball with the pneumatic valve seat sealing surface completely without friction spinning °.
4. Continue to turn the handwheel, fell again pneumatic valve rod mechanical pressure sphere, the sphere close contact with the pneumatic valve seat, so as to achieve sealing effect.
5) counterclockwise rotation handwheel when pneumatic valve in a seated position. In pneumatic valve stem nut with thrust bearing, the pneumatic valve rod began to rise, and drive the ball begin to spin.
6. Continuous rotation handwheel, pneumatic valve rod will be to rise at the same time drive the sphere of pneumatic valve seat.
7) when the pneumatic valve will open, pneumatic valve stem of the precision of spiral curve groove tracks with embedded in which drives the ball guide pin interaction with pneumatic valve seat sealing surface completely without friction press anticlockwise turn.
today continue to turn the handwheel, when pneumatic valve rod reaches the limit position, the ball has been with the pneumatic valve rod reverse ° pneumatic valve is in full open position.
