High-precision speed type fluid switch electromagnetic valve

Abstract

The invention relates to the technical field of switch electromagnetic valves, in particular to a high-precision speed type fluid switch electromagnetic valve. The high-precision speed type fluid switch electromagnetic valve comprises an electromagnetic valve body, a water flow detection assembly is installed at the position of a water inlet of the electromagnetic valve body, the water flow detection assembly comprises a fixed impeller, a magnetic pole rotor and a second supporting base, the magnetic pole rotor is arranged between the fixed impeller and the second supporting base, the fixed impeller is arranged on the side close to the water inlet, the other end of the magnetic pole rotor is rotationally connected with the second supporting base through a supporting shaft, a ball is arranged between the end of the supporting shaft and the second supporting base, two pairs of magnetic poles N and S are arranged on the magnetic pole rotor, and a Hall sensing assembly is arranged at the position, right opposite to the magnetic pole rotor, of a shell of the electromagnetic valve body. According to the high-precision speed type fluid switch electromagnetic valve, the corresponding speedof the flow detection assembly is increased, the single-time fluid flow detection precision is improved, meanwhile, the device is easy and convenient to assemble, and the production efficiency of thewhole device is improved.

Description

technical field [0001] The invention relates to the technical field of switching solenoid valves, in particular to a high-precision velocity fluid switching solenoid valve. Background technique [0002] Solenoid valve is an industrial equipment controlled by electromagnetic. It is an automatic basic component used to control fluid. In order to diversify the functions of the solenoid valve, a flow detection element will be installed at the water inlet of the solenoid valve. The rotating blades in the prior art are all It is connected through the rotation of the rotating shaft and the support seat. Under the impact of water, a large friction force will be generated between the rotating shaft and the support seat, resulting in a slow response speed when the water flow is detected, and most of the potential energy of the water is used to consume the above. Friction, if used in an environment with poor water quality, will directly cause the shaft and the support seat to be stuck....
