Control mechanism for seal water valve and seal water valve

Abstract

The invention discloses a control mechanism for a seal water valve and the seal water valve. The control mechanism for the seal water valve comprises a stator blade mechanism fixedly sealed and covered on a water inlet or a water outlet of a valve inner cavity of the seal water valve and used for forming a fixed circulation channel, a rotor plate mechanism used for forming a movable circulation channel and fit to and rotatably matched with the stator blade mechanism so as to control a water flow amount, and a fastening piece used for sealing an assembly port of a sealed and covered valve bodyand compressing and fitting the rotor plate mechanism onto the stator blade mechanism along an axial direction so as to form axial fastening and positioning. Compression-fit seal between the fasteningpiece and the rotor plate mechanism and compression-fit seal between the rotor plate mechanism and the stator blade mechanism form a double-layer dynamic seal structure. The whole structure is simple, seal links are less, all dynamic seal contacting a water flow adopts binding faces with mirror surface brightness levels for compression-fit seal, and the leakage problem brought by the wear duringa rotation process can be effectively avoided, so that the service life of the whole seal water valve is prolonged.

Description

technical field [0001] The invention relates to the technical field of water valve structures, in particular to a control mechanism for sealing water valves. In addition, the present invention also relates to a sealing water valve comprising the above-mentioned control mechanism for the sealing water valve. Background technique [0002] Angle valves and faucets are all existing household sealed water valves commonly used, and the water flow control part often adopts a spool mechanism. The structure of the existing spool mechanism is complicated, including the valve sleeve, valve stem, moving piece, static piece, sealing ring and other auxiliary structures. It is necessary to carry out double-layer waterproof and leak-proof inside the spool mechanism and between the spool mechanism and the valve body. Measures, and the double-layer waterproof and leak-proof measures will be exposed to the water flow erosion of the inner cavity of the valve body. Once there is leakage in one ...
