Small-caliber large-flow silent electromagnetic valve

Abstract

The invention provides a small-caliber large-flow silent electromagnetic valve. The small-caliber large-flow silent electromagnetic valve comprises a static iron core, a movable iron core, a coil component, a sealing piece, a reset spring, a vibration-proof spring, a valve body and other main parts. The static iron core is fixed through a hexagonal nut and a bolt. The coil component is wound outside the static iron core and the movable iron core. The static iron core and the movable iron core are equal in diameter. The movable iron core is internally provided with the reset spring. The upper end of the reset spring is fixedly connected with the sealing piece. The sealing piece is placed in a turned sealing groove. The material of the sealing piece is soft. The static iron core and the movable iron core are both made of special soft magnetic alloy materials. The vibration-proof spring is arranged outside a valve core component. The valve body is located at the lower end of the valve core component. Compared with the prior art, the small-caliber large-flow silent electromagnetic valve is simple in structure and convenient to use and not only thoroughly eliminates the noise of the electromagnetic valve during using but also effectively expands the application range of the electromagnetic valve on the basis of ensuring that the flow of the electromagnetic valve is not affected.

Description

technical field [0001] The invention relates to a solenoid valve, in particular to a small-diameter and high-flow silent solenoid valve. Background technique [0002] With the gradual improvement and popularization of automation control, the application fields of solenoid valves are also expanding, including some fields that require a quiet environment, such as: hotels, hospital wards, etc. As we all know, no matter how the structure of all solenoid valves changes, the principle is to generate a magnetic field through the electromagnetic coil, and then generate electromagnetic attraction force by the static iron core, thereby attracting the moving iron core to lift up and realize the opening of the solenoid valve. This principle is similar to The process of attracting positive and negative magnets together. In this process, due to the attraction of the dynamic and static iron cores, there will inevitably be a "click" impact sound. At present, the industry generally adopts ...
