Back-moving spring is provided with, valve seat, the other end of described matrix are fixedly installed in the position corresponding with valve body in described matrix
Filter is internally provided with, the filter includes top cover, filtering screen and hand block, and the outside of the top cover is circumferentially
Three screwed holes are evenly arranged with, the bottom surface of the top cover is fixedly installed filtering screen, and the top of the filter is fixed
It is provided with hand block.
Further, the junction of the top cover and matrix is provided with rubber seal.
Further, the filtering screen is arranged to circular arc, and its sectional area is arranged to the water outlet bore dia with matrix
It is equal.
Further, the mesh diameter of the filtering screen is arranged to 10-20 mesh, and it is arranged to stainless steel material.
Further, the water inlet end of described matrix is provided with flange with water side and connected.
Compared with prior art, the beneficial effects of the utility model are：Hydraulic control valve with filtering function is set in this
Meter is reasonable, simple in construction, is fixedly installed top cover by screw by the water side in matrix, is fixedly installed below top cover
Filtering screen, so that water carries out filtration treatment when passing through control valve, blocking of the debris to conveyance conduit is avoided, just
In dredging aqueduct, valve body and valve seat can also be observed by the through hole that matrix is set at top cover, avoided right
It is inconvenient caused by during control valve M R, it is convenient and practical, it is easy to promote.
