Stop valve capable of buffering medium kinetic energy

Technical Field

Background

The shut-off valve is also called a shut-off valve, and belongs to a forced sealing type valve, so that when the valve is closed, pressure must be applied to the valve clack so as to force the sealing surface not to leak. When a medium enters the valve from the lower part of the valve clack, the resistance which needs to be overcome by the operation force is the friction force of the valve rod and the filler and the thrust generated by the pressure of the medium, and the force for closing the valve is larger than the force for opening the valve, so that the diameter of the valve rod is larger, otherwise, the valve rod is in a bending fault.

Currently, the conventional shut-off valve is generally composed of a valve body, a valve rod and the like, and the valve opening or closing of the valve port is realized by the up-and-down movement of the valve rod in the valve body. In the prior art, when the valve port is opened, a medium enters the valve body, so that the kinetic energy is large, and the medium can flow unstably.
