Abstract
An electromagnetic valve seat free of water hammer chatter and a water path structure relate to a non-contact type automatic control electromagnetic valve seat in domestic water products. The electromagnetic valve seat is formed by connecting an electromagnetic valve, an electromagnetic valve seat body, a valve seat cylinder, a valve diaphragm and a water inlet supercharge ring. Down closing of the valve diaphragm is stopped or slowed down by means of the pushing effect of water inlet pressure of a water inlet hole, water hammer chatter caused by quick crack closing of the valve diaphragm is effectively reduced or avoided, service life of the valve diaphragm of the electromagnetic valve is prolonged, and vibration noise produced in closing of domestic water products is reduced.
Description
Technical field
The present invention relates to solenoid valve seat and waterway structure in a kind of contactless automatic control domestic water product, especially a kind of solenoid valve seat and waterway structure without the water hammer chatter.
Background technique
At present, the domestic water product of known contactless automatic control both at home and abroad, the water hammer chatter appears when product is closed, when hydraulic pressure is too high, the product water supply hose all vibrates to get spring, particularly the user that lives of multi-storey building is when water in the dead of night, and the noise of its water hammer vibration has reached the degree that disturbs residents.
Summary of the invention
The invention provides a kind of solenoid valve seat without the water hammer chatter and waterway structure, will solve exactly the water hammer chatter appears in contactless automatic control domestic water product when closing technical problem.
The technical solution adopted for the present invention to solve the technical problems is: be provided with solenoid valve seat in solenoid valve base, bottom at solenoid valve seat inwardly is provided with endoporus, be provided with pressurized water and pressure relief water interlayer in the neutral position of endoporus, the endoporus on pressurized water and pressure relief water interlayer both sides is provided with the supercharging water chamber, the top of both sides supercharging water chamber is respectively equipped with the pressure release flowing hole, the center, top of pressurized water and pressure relief water interlayer is provided with relief hole, pressurized water laterally is provided with the cylindrical minimum outer diameter that pressure relief water circulation road and solenoid valve seat middle part fall in the medium position of pressure relief water interlayer and connects, the solenoid valve seat bottom is provided with the valve matrix, be provided with in the central inner hole of valve matrix into the water pressurized ring, the solenoid valve seat cylindrical is provided with the valve seat cylinder barrel, valve seat cylinder barrel bottom is provided with water inlet and water outlet, insert in the valve seat cylinder barrel being provided with to be buckled on the solenoid valve seat bottom stage into the valve matrix of water pressurized ring, be assembled into the solenoid valve seat assembly, again solenoid valve is buckled in the solenoid valve seat upper end, is tightened in the product valve body with locking nut.When solenoid valve is opened, the movable iron core of electromagnetic valve sealing head is up, the relief hole that breaks away from the interior pressurized water of solenoid valve seat and center, pressure relief water interlayer top, relief hole is opened, the pressure release flowing hole of press water in the solenoid valve seat in pressurized water and the pressure relief water interlayer both sides supercharging water chamber by supercharging water chamber top, both sides pressurized water and the relief hole at center, pressure relief water interlayer top and the horizontal pressure relief water circulation road discharge pressure release in the middle part of pressurized water and the pressure relief water interlayer in the solenoid valve seat, flow to the water outlet of product valve body discharged to the pressure release rhone of valve seat cylinder barrel, at this moment, because the pressure of pressurized water and pressure relief water interlayer both sides supercharging water chamber is drained decompression in the solenoid valve seat, pressure in the supercharging water chamber and the intake pressure of water inlet have formed an obvious pressure difference, pressure in the supercharging water chamber is less than intake pressure, under the promotion of intake pressure, the valve matrix raises up to the direction of supercharging water chamber, instantaneous time has broken away from the water inlet arc sealing surface, its water inlet and water outlet are connected, the water inlet of water inlet is flowed out to water outlet, it is the water outlet of product water outlet face, in the water inlet of water inlet to same time that water outlet flows out, the supercharging of intaking of a part of water inlet supercharging groove by the water inlet pressurized ring in the valve matrix endoporus pressurized water and supercharging water chamber on pressure relief water interlayer both sides in the solenoid valve seat, when closed electromagnetic valve, the movable iron core of electromagnetic valve sealing head is descending, block pressurized water in the solenoid valve seat endoporus and the relief hole at center, pressure relief water interlayer top, the water of institute's supercharging is drained nowhere in pressurized water and the pressure relief water interlayer both sides supercharging water chamber, pressure in the supercharging water chamber just increases gradually, force the valve matrix to the direction of water inlet arc sealing surface to lower convexity, its to the speed of lower convexity again under the promotion of water inlet intake pressure, stop or the speed of valve matrix to lower convexity that slowed down, cause the valve matrix slowly near and be adjacent to the water inlet arc sealing surface, until close the water inlet, be product water outlet face sealing, finish a work cycle.
The invention has the beneficial effects as follows: because the change of solenoid valve seat waterway structure, solenoid valve valve matrix is when closing into water, under the promotion of the intake pressure of water inlet, the closing velocity of prevention and the valve matrix that slowed down, make its valve matrix be slowly near and be adjacent to the water inlet arc sealing surface, rather than card crash quick closedown once, the phenomenon of its water hammer vibration is just overcome or has been avoided, thereby strengthened the working life of solenoid valve valve matrix, reduced the noise of the water hammer vibration of domestic water product when closing.
