Background
The axis of the valve rod of the manual stop valve is perpendicular to the sealing surface of the valve seat, so that the valve is very suitable for being used for cutting or adjusting media and throttling. Once the stop valve is in the open state, the contact between the sealing surfaces of the valve seat and the valve clack is no longer existed, so the mechanical abrasion of the sealing surfaces is small, and the valve seat and the valve clack of most stop valves are easy to repair or replace the sealing elements without detaching the whole valve from the pipeline, thereby being applicable to the occasions that the valve and the pipeline are welded into a whole. The direction of flow of the medium through such valves changes, so that the flow resistance of the shut-off valve is higher than that of other valves.
At present, modern machinery is widely used, various valves are layered endlessly, and the manual stop valve is always incapable of well solving the problems of insufficient closing force due to flushing and no good closing force and no damage caused by expansion with heat and contraction with cold after long-term use; meanwhile, the high pressure inside the stop valve cannot be effectively discharged after the stop valve is closed, and the pressure gauge can be damaged for a long time.
