Double-head control electromagnetic valve

Abstract

The invention discloses a double-head control electromagnetic valve. The double-head control electromagnetic valve comprises a valve head, wherein a coil assembly is arranged in the middle of the interior of the valve head, and the coil assembly is composed of a framework and an enameled wire wound around the framework; a fixed iron core assembly is arranged at one side of the coil assembly and composed of an ejector rod guide sleeve, a membrane, a fixed iron core and an ejector rod, the ejector rod guide sleeve is welded to one end of the ejector rod in a sleeving manner, the membrane is clamped on the end face of the fixed iron core in a limited manner, and the membrane is arranged on the outer surface of the ejector rod in a sliding and sleeving manner; and the diaphragm is attached tothe inner wall of one end of the valve head, and the ejector rod is connected with the fixed iron core in a penetrating manner. According to the double-head control electromagnetic valve, by the arrangement, the effect of controlling electromagnetic valves at the two ends to work can be achieved only through one coil, and compared with an existing technical scheme, the installation space is reduced by a certain proportion, the manufacturing cost is relatively reduced, and the use limitation is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of solenoid valves, in particular to a double-head control solenoid valve. Background technique [0002] Solenoid valve is an industrial equipment controlled by electromagnetic. It is an automatic basic component used to control fluid. It belongs to actuator and is not limited to hydraulic and pneumatic. It is used to adjust the direction, flow, speed and other parameters of the medium in the industrial control system. The solenoid valve can cooperate with different circuits to achieve the expected control, and the control accuracy and flexibility can be guaranteed. There are many kinds of solenoid valves. Solenoid valves play a role in different positions of the control system, the most commonly used are check valves, safety valves, directional control valves, speed regulating valves, etc. [0003] In the current solenoid valve industry, a single solenoid valve structure is widely used. One coil can only c...

AI Technical Summary

Problems solved by technology

[0003] In the current solenoid valve industry, a single solenoid valve structure is widely used. One coil can only control the action of one solenoid valve. If multiple solenoid valves need to be installed in the same machine at the same time, it needs to occupy a relatively large space. To install multiple solenoid valves, the limitations in actual use are relatively large
