Abstract

The invention provides an electromagnetic valve device capable of eliminating the negative pressure in the valve, and belongs to the technical field of electromagnetic valves. The problem that in theprior art, the negative pressure is easily generated in a valve body of an electromagnetic valve in the working process and the normal work is influenced is solved. The electromagnetic valve device comprises an electromagnetic valve body and a water knockout trap fixedly arranged at the bottom of the electromagnetic valve body and in sealed connection with the electromagnetic valve body. The electromagnetic valve body comprises an electromagnetic assembly and a valve body assembly. The valve body assembly comprises a valve rod sleeve matched and connected with a static iron core, a spring movably arranged in the valve rod sleeve, and a valve rod with a movable sealing head. The end, making contact with the movable sealing head, of the valve rod sleeve is fixedly provided with a first pressure balancing device. The movable sealing head is fixedly provided with a second pressure balancing device. The electromagnetic valve device capable of eliminating the negative pressure in the valve has the advantages of being simple in structure, convenient to use and low in cost, the pressure balance in the electromagnetic valve body can be realized, and the control over the output water flow can be realized so that the water flow can be prevented from backward flowing.

Description

technical field [0001] The invention belongs to the technical field of solenoid valves, and in particular relates to a solenoid valve device capable of eliminating negative pressure in a valve. Background technique [0002] In daily life, the water discharge solenoid valve is used as an intelligent switch. There are many water equipment connected to the tap water supply pipe. A water discharge solenoid valve is generally installed between the water supply pipe and the water use equipment to control the switch of the water flow. The working principle of the solenoid valve is electromagnetic The coil generates electromagnetic force to drive the seal to open or close the valve. [0003] In the prior art, because the solenoid valve needs to play a sealing role, the solenoid valve itself has good sealing performance. After the solenoid valve is energized, the valve stem does a work similar to the expansion and contraction of the piston in the valve stem sleeve, causing the soleno...
