Specific embodiment
Referring to attached drawing
A kind of plug-type control valve including valve body 1, valve core rod 4, is disposed with connector 1, disappears on 1 side of valve body
Sound device 1, muffler 2 602, opposite side are disposed with muffler 3 603, connector 2 702, connector 3 703, connector four
704, connector 1 in valve body 1 also by pipeline connection connector 4 704 corresponding to spool chamber,
The connector 1 of 1 side of valve body, muffler 1, muffler 2 602 and opposite side muffler 3 603, connect
First 2 702, connector 3 703, connector 4 704 are staggered respectively up and down along spool cavity direction, and connector 1 is in valve body 1
Spool chamber corresponding to also by pipeline connection connector 4 704
It is separated in spool chamber corresponding to every group of connector and muffler with segmentation set with holes, i.e., segmentation set is fixed setting
Correspond to above-mentioned each muffler and connector on spool cavity wall, separated, divided with the sealing of gasket 9 between each segmentation set
It puts on and is laid with three through-holes, valve core rod 4 passes through the segmentation set being arranged in spool chamber and gasket 9 to do reciprocating sliding, valve
Set the annular convex platform and three annular grooves there are four Unequal distance on core bar 4, annular groove be connect two neighboring connector or
