Modified-type electromagnetic valve

Abstract

The invention relates to the technical field of electromagnetic control equipment, and particularly discloses a modified-type electromagnetic valve. The modified-type electromagnetic valve comprises a valve body, a spring, a valve core, a fixed core and an electromagnetic coil, wherein the spring and the valve core are installed inside the valve body, one end of the valve core abuts against the spring, and the other end of the valve core protrudes and extends out of the valve body and is connected to a sliding core; the fixed core is installed outside the sliding core and is connected with the valve body; the electromagnetic coil is installed outside the fixed core. The modified-type electromagnetic valve is characterized in that the fixed core comprises a sleeve, a first sleeve shell and a second sleeve shell, wherein the first sleeve shell and the second sleeve shell are installed at the two ends of the sleeve respectively, the sleeve is made of non-magnetic materials, and the first sleeve shell and the second sleeve shell are made of magnetic materials; magnets or other magnetic pieces used cooperatively with the sliding core do not need to be additionally arranged on the electromagnetic valve, so that the complexity of the design structure is reduced greatly, furthermore, the assembling process is simplified, and the control precision of the electromagnetic valve is improved.

Description

technical field The invention relates to the technical field of electromagnetic control equipment, in particular to an improved electromagnetic valve. Background technique Solenoid valve (Electromagneticvalve) is an industrial equipment controlled by electromagnetic force. It is an automatic basic component used to control fluid, and is used to adjust the flow direction, flow rate, speed and other parameters of fluid medium. Solenoid valves need to be installed on various parts in the specific use process, such as automobile engines, etc. In most cases, the working space is small, which requires that the product size of the solenoid valve should not be too large. Of course, if the components of the solenoid valve are relatively large If there are too many components, the design and structure of the solenoid valve will be complicated. On the one hand, the size of the product will be increased, and on the other hand, the working accuracy of the solenoid valve will be reduced ...

Solenoid valves need to be installed on various parts in the specific use process, such as automobile engines, etc. In most cases, the working space is small, which requires that the product size of the solenoid valve should not be too large. Of course, if the components of the solenoid valve are relatively large If there are too many components, the design structure of the solenoid valve will be complicated. On the one hand, the size of the product will be increased, and on the other hand, the working accuracy of the solenoid valve will be reduced due to more components.

Most of the existing solenoid valves are equipped with electromagnetic coils, movable cores and magnets or other magnetic parts that cooperate with the movable cores. Installing additional magnets or other magnetic parts in the small design size of the solenoid valve will not only increase the difficulty of product processing , which also makes the design structure of the solenoid valve complex and the assembly process various, it is necessary to improve the design for the shortcomings of the existing solenoid valve
