The further design is: the valve rod is provided with a key slot, and the positioning block and the positioning pin are clamped in the key slot.
The further design is: the side of the valve body is provided with a pressure relief valve.
The further design is: the outer circle of the bearing cover is provided with a disc screw and an oil cup.
The further design is: an opening nut is arranged at the uppermost end of the valve rod, an opening indication board is bound outside the protective cover, and scales of the opening indication board correspond to sharp angles of the opening nut.
The further design is: the inner hole of the valve seat, the front end of the valve rod and the front end of the righting sleeve are inlaid with integral hard alloy.
The further design is: the wear-resistant lining is made of hard alloy.
The further design is: the front end of the valve rod adopts a double conical surface wedge block.
The utility model has the advantages that:
1. the valve seat inner hole, the valve rod front end and the centralizing sleeve front end are inlaid with integral hard alloy, and the wear-resistant lining adopts the integral hard alloy, so that the valve seat inner hole, the valve rod front end and the centralizing sleeve front end have strong scouring resistance and corrosion resistance and long service life.
2. The front end of the valve rod adopts a double-conical wedge block, has certain diversion and diversion effects, and reduces the scouring of fluid to the valve body.
3. The valve rod is provided with a key groove, and a positioning block and a positioning pin are arranged in the key groove, so that the direction of the wedge-shaped block at the front end of the valve rod is always unchanged.
4. The valve is provided with an opening indication board, which corresponds to an opening nut at the upper end of the valve rod, and the opening and the flow of the valve are more accurate.
5. The valve is provided with two bearings, and the moment is smaller when the valve is opened and closed.
