Abstract
An electromagnetic regulation valve is composed of valve body, valve cover, valve flap module, iron core module and electromagnetic coil. A pressure cavity formed between valve flap module and valve cover has the flow guide hole and draining hole communicated respectively to inlet and outlet of valve body. A non-magnetic retaining ring is arranged between iron core and blocking head for preventing the generation of closed magnetic loop, which can decrease the sensitivity of iron core movement.
Description
Technical field
The present invention relates to a kind of valve, specifically about a kind of solenoid electric valve.
Background technique
The structure of solenoid valve generally is made up of valve body, valve gap, flap assembly, core assembly and electromagnetic coil, by the on off state of the Control of Voltage solenoid valve of electromagnetic coil.Yet, existing solenoid valve is behind coil electricity, the electromagnetic force that produces when coil is during greater than the elastic force of iron core spring, and iron core just will be drawn onto the end and iron core conduit plug is close to, the formation closed magnetic circuit, have only when electromagnetic coil voltage and drop near zero the time, iron core just can be released, and can not control the upper-lower position of electric core with the size of electromagnetic coil voltage, can only realize standard-sized sheet or complete shut-down control to valve, so aperture that can not the continuous control valve is rate of discharge and pressure that can't regulating valve.
Summary of the invention
The objective of the invention is the deficiency at the prior art existence, providing a kind of can realize valve export flow and the continuous electromagnetic type modulating valve of regulating of pressure according to the size control iron core position of electromagnetic coil operating voltage.
Realize the technological scheme of the object of the invention, comprise valve body, valve gap, flap assembly, core assembly and electromagnetic coil, constitute a pressure chamber between flap assembly and the valve gap, this pressure chamber is communicated with valve body suction side and outlet side respectively by pod apertures and discharge orifice, mainly be the lower position that iron core is arranged in electromagnetic coil, non magnetic ring washer is set between iron core and plug.
The present invention's beneficial effect compared with prior art is the middle lower position that iron core is arranged on electromagnetic coil, by the elastic force of choose reasonable iron core spring, iron core is parked on the corresponding position under different coil working voltages.Simultaneously, non magnetic ring washer is set between iron core and plug, keeps the gap between iron core and the plug, prevent that iron core and plug from forming closed magnetic circuit, make iron core sensitive moving down of energy when voltage descends, realize the control of voltage, reach the adjusting of valve export flow and pressure flap position.
