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 the solenoid valve seat in a kind of contactless automatic control domestic water product and waterway structure, especially a kind of solenoid valve seat without water hammer chatter and waterway structure.
Background technique
At present, the domestic water product of known domestic and international contactless automatic control, water hammer chatter is there is when product is closed, when hydraulic pressure is too high, product water supply hose all vibrates to obtain spring, particularly the user that lives of multi-storey building is when using water in the dead of night, and the noise of its water hammer vibration reaches the degree disturbed residents.
Summary of the invention
The invention provides a kind of solenoid valve seat without water hammer chatter and waterway structure, water hammer chatter appears in contactless automatic control domestic water product technical problem when closing will being solved exactly.
The technical solution adopted for the present invention to solve the technical problems is: be provided with solenoid valve seat in solenoid valve base, inwardly endoporus is provided with in the bottom of solenoid valve seat, pressurized water and pressure relief water interlayer is provided with in the neutral position of endoporus, the endoporus on pressurized water and pressure relief water interlayer both sides is provided with supercharging water chamber, the top of both sides supercharging water chamber is respectively equipped with pressure release flowing hole, the center, top of pressurized water and pressure relief water interlayer is provided with relief hole, the cylindrical minimum outer diameter fallen in the middle part of pressure relief water circulation road and solenoid valve seat together with the medium position of pressurized water and pressure relief water interlayer is laterally provided with connects, valve matrix is provided with bottom solenoid valve seat, be provided with in the central bore of valve matrix into water pressurized ring, solenoid valve seat cylindrical is provided with valve seat cylinder barrel, valve seat cylinder barrel bottom is provided with water inlet and water outlet, insert in valve seat cylinder barrel by being provided with to be buckled in solenoid valve seat bottom stage into the valve matrix of water pressurized ring, be assembled into solenoid valve seat assembly, again solenoid valve is buckled in solenoid valve seat upper end, be tightened in product valve body with locking nut.When solenoid valve is opened, movable iron core of electromagnetic valve sealing head is up, depart from the relief hole at pressurized water and center, pressure relief water interlayer top in solenoid valve seat, relief hole is opened, press water in solenoid valve seat in pressurized water and pressure relief water interlayer both sides supercharging water chamber discharges pressure release by the pressure release flowing hole on supercharging water chamber top, the both sides horizontal pressure relief water circulation road in the middle part of the relief hole at pressurized water in solenoid valve seat and center, pressure relief water interlayer top and pressurized water and pressure relief water interlayer, pressure release rhone discharged to valve seat cylinder barrel flows to the water outlet of product valve body, at this moment, because the pressure of pressurized water in solenoid valve seat and pressure relief water interlayer both sides supercharging water chamber is drained decompression, pressure in supercharging water chamber and the intake pressure of water inlet define an obvious pressure difference, pressure in supercharging water chamber is less than intake pressure, under the promotion of intake pressure, valve matrix raises up to the direction of supercharging water chamber, instantaneous time has departed from 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, i.e. product water outlet face water outlet, the same time that water inlet in water inlet is flowed out to water outlet, part water inlet to be intake supercharging to the supercharging water chamber on pressurized water in solenoid valve seat and pressure relief water interlayer both sides by the supercharging groove of the water inlet pressurized ring in valve matrix endoporus, when closed electromagnetic valve, movable iron core of electromagnetic valve sealing head is descending, block the relief hole at pressurized water in solenoid valve seat endoporus and center, pressure relief water interlayer top, in pressurized water and pressure relief water interlayer both sides supercharging water chamber, the water of institute's supercharging is drained nowhere, pressure in supercharging water chamber just increases gradually, force valve matrix to the direction of water inlet arc sealing surface to lower convexity, its speed to lower convexity is again under the promotion of water inlet intake pressure, stop or the speed of valve matrix to lower convexity that slowed down, cause valve matrix slowly near and be adjacent to water inlet arc sealing surface, until closedown water inlet, i.e. product water outlet face sealing, complete a work cycle.
The invention has the beneficial effects as follows: due to the change of solenoid valve seat waterway structure, solenoid valve valve matrix is when closing water inlet, 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 water inlet arc sealing surface, instead of card crash quick closedown once, the phenomenon of its water hammer vibration is just overcome or is avoided, thus enhance the working life of solenoid valve valve matrix, reduce the noise of the water hammer vibration of domestic water product when closing.
