Problems solved by technology

This type of scale is different from scaling in high-temperature boilers and other equipment, but is similar to the way of mineral crystallization attached to the movement of the trace exhaust valve and the surface of the sealing internal parts. The strong adhesion is difficult to remove, and finally affects the trace exhaust. The opening and closing action and sealing of the valve will cause the valve to leak, and in severe cases, the valve function will fail

Abstract

The invention discloses an anti-scaling type trace exhaust valve. The anti-scaling type trace exhaust valve comprises a valve body, wherein the valve body is internally provided with a lever assembly, the lever assembly is connected with a floating ball, and the valve body is also internally provided with a magnetic material of which the magnetic field range acts on the surface of the lever assembly. According to the anti-scaling type trace exhaust valve disclosed by the invention, the magnetic material is arranged in the anti-scaling type trace exhaust valve, a magnetic field of the magnetic material covers the surface of the lever assembly, thus the polarity is changed when ions pass through the surface of the lever assembly, the nucleation rate is increased, a large number of micro-crystals can be generated, the stability of the micro-crystals is better, the generation of macro-crystals is restrained, the scaling probability on the surface of the lever assembly is greatly reduced, the normal work of the lever assembly is ensured, the phenomena of clamping and blocking cannot happen, the structure is simple, the consumption of electric energy is not needed, and the practical performance is better.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to an anti-scaling micro exhaust valve. technical background [0002] Most of the trace exhaust valves in the valve industry are used in sewage and raw water systems, and there are relatively serious scaling phenomena, especially in northern China, where the water quality is alkaline, the hardness is high, and the scaling phenomenon is more serious. This type of scale is different from scaling in high-temperature boilers and other equipment, but is similar to the way of mineral crystallization attached to the movement of the trace exhaust valve and the surface of the sealing internal parts. The strong adhesion is difficult to remove, and finally affects the trace exhaust. The opening and closing action and sealing of the valve will cause the valve to leak, and in severe cases, the valve function will fail. Contents of the invention [0003] The present invention aims at the above-...
