Zero friction flexible pneumatic pneumatic valve valve industry _ pneumatic components factory

Pneumatic pneumatic valve zero friction flexible pneumatic pneumatic valve core technology: open or close the valve pneumatic sealing face away from the valve seat sealing surface, in the process of pneumatic body completely dangling in the valve body cavity, aerodynamic body movement with the valve seat sealing surface no friction, achieve zero wear effect. The core of this valve seal abnormity pneumatic structure reasonable, unique aerodynamic body top along the flow direction of medium has gouges where whole pieces were missing, aerodynamic body with open and close function, a support wedge between aerodynamic body gouges where whole pieces were missing and four connecting rod assembly, assembly and valve stem bottom connection with pneumatic form a whole body, ascending and descending movement in the stem, of the bottom of the stem drive component to the aerodynamic body closed or open, composite components can adjust the volume of the pneumatic body becomes large or small, the valve seal has compensation function, make the valve sealing performance more reliable. At the same time, under a state of emergency in need of emergency cut-off can compulsory seal. Zero friction flexible pneumatic pneumatic valve features: (1) because the pneumatic sealing body in the process of spinning and basic completely out of seat tightness, no friction, not only, also be deft, because will not scratch sealing surface, long service life. (2) fast cutting, micro wear, small torque, sealing good compensation. Zero friction flexible pneumatic pneumatic valve operation method: when the valve is fully open, When the handle and piping in the same direction) To close the valve. （ 1) To handle clockwise to guide slot vertical slot part of the support. （ 2) By rotating the handwheel clockwise until it turn to be not moved, at this time, the aerodynamic body is open, the valve is in sealed condition. : (when the valve is closed When the handle and vertical pipe) To open the valve. ( 1) The handwheel counterclockwise, handle rise to support guide slot horizontal slot position, at this time, the pneumatic body closed at the same time from the valve seat sealing surface. ( 2) Push the handle counterclockwise 90 °, the handle and piping in the same direction, the valve opens. Note: zero friction flexible pneumatic pneumatic valve torque is small, do not need to borrow other auxiliary tool to switch, otherwise may cause damage to the valve. Only can be used in urgent need to cut off the auxiliary tool for switch operation.
