Description
Technical field
A kind of valve is the utility model is related to, is related to a kind of stop valve of steel design, in particular for various pipeline systems
In system, block, connect, controlling the valve of fluid flow.
Background technology
Current mesolow pipe valve uses stop valve more, and stop valve easily leaks, in long-term use of friction process,
Sealing between valve rod and valve body is easiest to leak.Also, stop valve is not suitable for the conveying of elevated pressures medium.
The content of the invention
The purpose of this utility model is to solve the above problems, and the utility model proposes a kind of seamless steel of good seal performance
Pipe welds stop valve.
The technical solution adopted in the utility model is：A kind of seamless steel pipe welds stop valve, including Straight valve body, valve body
Top is provided with valve port, and valve port top connects the flap of cone shape, is threadedly coupled between valve port and flap, flap upper end is provided with valve
Bar, the valve pocket on the outside of valve rod are fixedly connected with the fixed cover of body top by ring flange, and valve rod corresponding to valve pocket is provided with branch
Pushing out ring, is provided with sealing ring above support ring, and valve pocket upper end is by the nut that one end is stretched into inside valve pocket by sealing ring and support ring
Compress, it is characterised in that the bottom of support ring is plane, is triangle at the top of support ring, and sealing ring includes upper sealing ring with
Sealing ring, upper sealing ring top are plane, and upper sealing ring bottom is provided with triangular groove, is triangle at the top of lower sealing ring, under
Sealing ring bottom is provided with triangular groove, triangle, triangular groove, the lower sealing ring of lower sealing ring bottom at the top of support ring
The triangle at top, upper sealed bottom triangular groove between shape, size matching.
Optimization of the present utility model, sealing gasket is provided between valve port and flap.
Further optimization, sealing ring material is politef, and support ring material is carbon structural steels.
Operation principle of the present utility model is：Support ring, upper sealing ring and the matching of lower sealing ring interpolation, in valve pocket upper end spiral shell
Under female and support ring extruding, upper sealing ring and lower sealing ring are deformed, and are extruded to valve sleeving inner wall, it is ensured that sealing.
After pumped (conveying) medium enters valve body, under the pumped (conveying) medium pressure extrusion of lower section, upper sealing ring and lower sealing ring are pressed further by
Deformation, further increases the sealing property at valve rod, and using upper sealing ring and lower sealing ring crimp alleviate it is defeated
Damage of the pressure medium to valve body components is sent, the utility model is applied to the conveying of the larger medium of pressure.
The beneficial effects of the utility model are：The utility model improves the sealing property at valve rod, and suitable for compared with
The conveying of high pressure power media.
