An electric switch check valve

Abstract

The invention discloses an electric switch inverted valve. The electric switch inverted valve comprises an inverted valve pipeline, the inverted valve pipeline comprises a water inlet terminal and a water outlet terminal, the inverted valve pipeline also comprises an electric switch valve terminal which is communicated with the inverted valve pipeline, the interior of the electric switch valve terminal is provided with normally open contacts, an insulated rubber jacket and a mobile valve block, the rubber jacket port of the insulated rubber jacket is in seal connection with the inner wall of the electric switch valve terminal, the normally open contacts comprise a first normally open contact, a second normally open contact, and a third normally open contact arranged under the second normally open contact, the first normally open contact and the second normally open contact are symmetrically arranged on the upper part of the inner wall of the electric switch valve terminal, the mobile valve block comprises a first mobile valve block unit arranged between the first normally open contact and the third normally open contact, and the insulated sleeve is arranged on the bottom of the inner wall of the electric switch valve terminal. The electric switch inverted valve is simple in structure, easy and simple to operate, convenient to popularize and accurate in measurement, and is not susceptible to environment, and therefore the problem that the water supply of the user side is cut off irregularly is solved.

Description

technical field [0001] The invention relates to a check valve, in particular to an electric switch check valve. Background technique [0002] The check valve is a kind of automatic valve, its main function is to prevent the reverse flow of the medium, prevent the reversal of the pump and the drive motor, and discharge the container medium; the traditional check valve has a complex structure, is inconvenient to maintain and cannot be used to control the on-off of the current ; [0003] Through many years of work on maintenance machines, electricians and hydropower installations, it has been found that at present, buoyancy switches are often used in pools, water towers or water tanks. This method is affected by buoyancy, water flow priority and manpower settings, which is random and prone to inaccurate measurement. , It is greatly affected by the environment, which leads to the disadvantages of irregular water cut-off at the user end. Contents of the invention [0004] The...

[0003] Through many years of work on maintenance machines, electricians and hydropower installations, it has been found that at present, buoyancy switches are often used in pools, water towers or water tanks. This method is affected by buoyancy, water flow priority and manpower settings, which is random and prone to inaccurate measurement. , It is greatly affected by the environment, which leads to the disadvantages of irregular water cutoffs at the user end
