Description

Triangular stop valve with conical valve block

Technical Field

The invention relates to the field of valves, in particular to a triangular stop valve with a conical valve block.

Background

The angle valve is also called triangle valve, angle valve, and angle water valve. This is because the pipe has a 90-degree corner shape at the angle valve, and is called an angle valve, or a dog-leg water valve. The existing triangular valve is mainly divided into a triangular ball valve and a triangular stop valve, the triangular stop valve is similar to a common linear stop valve in principle, a sealing cover with a plane is arranged at the bottom of a valve block, a water flow stopping effect is achieved when a water inlet is sealed, however, the size of the stop valve is still large, the occupied space of a valve rod is large, the valve rod cannot be fully stored and protected, the guiding effect on water flow in the opening and closing process is insufficient, the situation that local water pressure is too high is easily caused, and the structure of internal parts of the complex body is damaged.
