A New Solenoid Valve

Abstract

The invention discloses a novel electromagnetic valve. The novel electromagnetic valve comprises a valve body, a valve cover, a diaphragm and a movable iron core, wherein the valve body and the valve cover form a cavity; a plurality of openings communicated with the cavity are formed in the valve cover; the diaphragm is arranged inside the cavity; the movable iron core can move relative to the valve body; the movable iron core comprises a rocker, at least one ejector rod and a connecting rod; the rocker is arranged on the valve body in a rotating manner to form a lever structure; the at least one ejector rod is connected with the rocker; the connecting rod is arranged on the valve body in a rotating manner, and is connected with the movable iron core and the ejector rod respectively so as to drive the ejector rod by the movable iron core to do linear reciprocating movement; the diaphragm is arranged between the openings and the ejector rod, and sealing parts are arranged at positions, corresponding to the openings, of the diaphragm; the sealing parts can close or open the corresponding openings along with the movement of the ejector rod. Parallel contact of the diaphragm and a valve port is ensured, so that pressure resistance and sealing performance are improved; the influence of the dimensional accuracy of a component on the performance of a product is relatively small, so that the cost of the component is reduced; the power consumption of the electromagnetic valve is effectively lowered, and the stability and the sensitivity of the electromagnetic valve are improved.

Description

technical field [0001] The invention relates to the field of fluid control, in particular to an electromagnetic valve. Background technique [0002] As a kind of fluid control equipment, solenoid valve is widely used in various fields of modern industry. According to its working mode and principle of action, electromagnetic valves are divided into many types. One type of diaphragm valve controls the opening and closing of the valve port through the deformation of the diaphragm. The diaphragm valve in the prior art uses an electromagnet to push the rocker, and then The rocker pushes the diaphragm, and in the prior art, it also includes a first elastic piece for rocker reset and a second elastic piece for electromagnet reset, wherein the force directions of the first and second elastic pieces are opposite, so When the second elastic member pushes the electromagnet to move, it not only bears the gravity of the electromagnet and its subsidiary structure, but also bears the elas...

According to its working mode and principle of action, electromagnetic valves are divided into many types. One type of diaphragm valve controls the opening and closing of the valve port through the deformation of the diaphragm. The diaphragm valve in the prior art uses an electromagnet to push the rocker, and then The rocker pushes the diaphragm, and in the prior art, it also includes a first elastic piece for rocker reset and a second elastic piece for electromagnet reset, wherein the force directions of the first and second elastic pieces are opposite, so When the second elastic member pushes the electromagnet to move, it not only bears the gravity of the electromagnet and its subsidiary structure, but also bears the elastic force of the first elastic member being compressed, which means that the second elastic member must have sufficient elastic force, As a result, the cost of the second elastic part increases. In addition, the electromagnet must also overcome a greater reaction force when compressing the second elastic part, which is not conducive to the processing of the solenoid valve.
