Valve opened of control valve core by magnetic suspension method

Abstract

A valve whose valve core is opened by magnetic suspending method features that its handle, central axle of valve body and valve core are connected indirectly, that is, connected in magnetic suspending mode, resulting in no leakage, small size and long service life.

Description

technical field [0001] The invention belongs to a valve, in particular to a valve which uses a magnetic levitation method to control the opening of a valve core. Background technique [0002] Existing various switching valves, its valve core adopts metal parts such as cast iron, iron copper and rubber parts to be combined mostly. When in use, dripping occurs due to easy wear and aging of rubber parts, and the service life is very short. A valve that can be used tens of thousands of times has been introduced on the market. Its structure is composed of a valve body, a valve core and a rotating shaft. For the moving piece, the upper and lower fixed pieces are penetrated with a water cavity and separated by a spacer. The moving piece has a non-through water cavity and is separated by a spacer. The moving piece is embedded by the rotating shaft. By rotating with a fixed handle, the upper fixed piece There is an O-ring on it, which is pressed by the gland. By changing the relat...

AI Technical Summary

Problems solved by technology

Compared with the traditional valve, the service life of the above-mentioned valve has been improved many times, but because the connecting part of the shaft and the valve body is sealed by an O-ring or a rubber pad, the sealing ring is still worn when the valve is switched on and off, causing the shaft to Leakage occurs at the connection with the valve body
