Detailed Plug Valve Description
The plug valve, is the one take the cock body with hole as the start and
stop part, and realized the start and stop function by the cock and valve
stem.
During the revolve procedure, the sealing specific pressure in the
vice - sealing room of the cock is changing until it get to the full - open
or close position.
The dual - glove seal ring can not only fix the PTFE bush in the body not
shift, but also absorb the micro - distortion of the cutting sleeve which
resulted from the temperature change.
The entry and exit of the body design is dual - glove seal structure. Produce enough sealing specific pressure and
zero - leakage. Between the cutting sleeve and the
cock there is strong rubbing function that can import the service life of
the sealing face.
The upper end of the cock shift make up of the PTFE film, O - ring and the
washer, which can regulate the sealing specific pressure betwwen the
sealing faces to make the cock moving nimbly as well as ensure the seal
of the connection between the entry and exit ends and the flange. In the PTFE cutting sleeve, use the filler according
to the operation temperature and working medium, that is well lubricated
and with long life.
The whole sealing procedure can has approximately nothing to do with the pressure in the pipe.
The plug valve, with its but welding end X43F as base connected with
socket welding end. Its largest pressure can reach ANSI900Lb.
