Spring, spring base, pad and nut, described bonnet is arranged on inside adjusting handle, and screw rod connects regulating valve stem, and regulating valve stem is certainly
Up to lower sheathed bonnet respectively and regulation joint, adjust joint bottom setting spring base, and described spring is vertically provided at spring base
Interior, described jump ring is fastened in order to spacing bonnet on regulating valve stem, and described spring base bottom is provided with pad, and pad passes through nut
Fixing, described pad bottom connects upper drainage screen.
Preferably, it is provided with filtration bowl outside described lower drainage screen, described filtration bowl is connected with housing, its junction is arranged
There is sealing ring.
Preferably, described filter screen bracket is spring bracing.
Compared with prior art, this utility model has following beneficial effect：
Pressure regulation fore filter of the present utility model, the filter cavity being used is designed as upper and lower two-layer, when normally using
Current entrance outside filter cavity, drainage screen to realize the effect filtered；When carrying out backwash, open flushing valve, utilize
Lower drainage screen is sunk by the pressure of water, and the inside that now current enter into upper drainage screen from the outside of filter cavity is filtered,
A part of flow direction clear water output ensures just to commonly use water, and under some flow direction, the lower drainage screen of part is recoiled
Wash it is achieved that the purpose of filter one side backwash one side normal water supply, facilitate production, the life of people.
