Abstract

An elastic contact of a floating ball liquid level switch belongs to the technical field of a floating ball liquid level switch. By the elastic contact, the problem that multiple contacts in an existing floating ball liquid level switch cannot be simultaneously contacted to affect the usage of a liquid level switch is solved. A baffle plate is fixedly connected to a shell via a screw, a first magnetic post and a fixed sleeve are simultaneously, rotatably and fixedly connected to the shell by a pin shaft, two studs are arranged on each baffle plate, a first contact is arranged at one end, nearto the fixed sleeve, of each stud, an outer profile of the fixed sleeve is of a cuboid structure, chamfering angels are processed on two edges, vertically and oppositely arranged, of the bottom of thefixed sleeve, a first U-shaped guide sheet is arranged on each chamfering angle along a length direction thereof in a buckling way, two elastic sheets are parallel to each other and are arranged at the first U-shaped guide sheets in an inclination way, or the two elastic sheets are arranged in a splayed way. The elastic contact is used for continuously measuring, controlling and monitoring a liquid level or a phase interface of various openings or in a pressure container.

Description

technical field [0001] The invention relates to an elastic contact of a float liquid level switch, belonging to the technical field of float liquid level switches. Background technique [0002] Float level switches are widely used in petroleum, chemical, light industry, municipal, environmental protection and other industries for continuous measurement, control and monitoring of liquid levels or phase interfaces in various openings or pressure vessels. It does not contain bellows, springs, seals and other components that cause failures, but uses a float to drive the internal magnetic column of the switch, and the simple lever makes the switch act instantly. Float level switch is a liquid level control device with simple structure and convenient use. Compared with ordinary mechanical switches, it has smaller volume, faster speed and longer service life. Compared with electronic switches, it has the characteristics of strong load impact resistance. . [0003] In order to mee...
