Cylindrical ptfe sealing plug seal principle of pneumatic valve (4)

cylindrical PTFE seal cock pneumatic valve, pneumatic valve and pneumatic valve core is compatible with PTFE casing, it USES compressed air compression nut on the seat body, the seal by the pneumatic valve core and certain interference, require iron fluoride walk-on tube, that is, to seal for PTFE casing extrusion pressure pneumatic valve core. Therefore, pneumatic valve core and teflon casing surface roughness requirements, must be small, geometry error should be small, in order to achieve the required sealing pressure ratio. If you need to compress the sleeve pneumatic valve seat, to restore the seal casing, pneumatic valve closed position must be yellow, in order to prevent iron fluorine bit player tube pressure port.
