Between be equipped with division surface, division surface is provided with through-hole, and valve rod through valve seat extend into division surface hereinafter, valve disc is connect with valve plug, described
Valve body import is equipped with suction flange, and valve outlet is equipped with outlet(discharge) flange, is equipped with strainer in the valve body import, strainer by ring flat-plate with
Filter core composition, the valve body import flange center are equipped with loop concave, the ring flat-plate of strainer be located in the loop concave and with into
Mouth flanged joint and fixation.
As the optimal technical scheme of the utility model, the valve seat center is equipped with stuffing hole, and the middle section of valve rod is logical
Cross stuffing hole, between valve rod and the hole wall of stuffing hole be filled with airtight and watertight padding, the upper surface of described stuffing hole be equipped with gland, gland with
Valve seat is connected and is fixed；It is equipped with spring between the valve rod and valve body, is equipped with spring capping above spring, spring capping is equipped with
The nut for connecting and fixing with valve rod.
As the optimal technical scheme of the utility model, the valve seat and valve body are set as overall structure, and the spring is arranged
Around valve seat.
As the optimal technical scheme of the utility model, the flat spiral shell of locking is additionally provided on the nut above the spring capping
It is female.
As the optimal technical scheme of the utility model, the axis of the valve body import and the axis of valve outlet are mutually flat
Row.
The beneficial effects of the utility model are: compared with the existing technology, import of the utility model in self-closing discharge valve
Interior setting strainer can effectively prevent the entrance of sundries, to keep the sealing surface of discharge valve not easy to wear, keep sealed reliable not
Leakage.Meanwhile airtight and watertight padding is filled in the stuffing hole at valve seat center, the division surface of valve disc and valve body forms good sealing and connects
It connects.The structure of the utility model is more compact, good seal, intensity are high, long service life.
