Embodiment

[0016] Such as figure 1 As shown, a high-voltage switch of the present invention includes a lower cover body 1 connected in parallel on a liquid pipeline and an upper cover body 2 provided on the lower cover body 1 through screw butt connection. The upper cover body 2 and the lower cover body 1 are common The valve core accommodating cavity 3 is enclosed, and the micro switch 4 connected with the external electrical equipment and the spool assembly connected with the liquid pipeline are installed in the spool accommodating cavity 3, wherein the spool assembly includes the valve core assembly enclosed in the lower cover 1 The elastic diaphragm 61 on the docking interface 5 is located in the middle of the lower cover 1. The elastic diaphragm 61 includes a supporting film 611 covering the docking interface 5, and the edge of the supporting film 611 extends upward to form a U-shaped deformation Ring 612, the opening of the deformation ring 612 faces downward and extends horizontall...

Abstract

The invention discloses a high-voltage switch, provides a high-voltage switch which is simple in structure, high in reliability and long in service life, and solves technical problems existing in the prior art that the high-voltage switch is poor in sensitivity, an elastic diaphragm and a micro switch contact are easy to wear, the service life is short and the like. The high-voltage switch comprises a lower cover body connected to a fluid pipeline in parallel and an upper cover body covering the lower cover body, wherein the upper cover body and the lower cover body form a valve element accommodating cavity in an enclosing manner together, the valve element accommodating cavity is internally provided with a micro switch connected with external electrical equipment and a valve element assembly connected with the fluid pipelines, the valve element assembly comprises an elastic diaphragm covering an interface of the lower cover body in a sealing manner, a triggering movable block is clamped between a contact of a micro switch and the elastic diaphragm, one end of the triggering movable block is slidably clamped at the inner wall surface of the valve element accommodating cavity, the upper part of the other end of the triggering movable block is abutted against the inner wall surface of the upper cover body through a compression spring, and the triggering movable block is contacted with the contact and triggers the micro switch under driving of the elastic diaphragm.

Description

Technical field [0001] The invention relates to a high-voltage switch, in particular to a high-voltage switch with a simple structure, high reliability and long service life. Background technique [0002] The working principle of the pressure switch is: when the pressure in the system is higher than the rated safe pressure, the disc in the sensor moves instantaneously, and the switch connector is pushed to disconnect through the connecting guide rod. When the pressure drops to the rated recovery value, the disc Instant reset, the switch automatically resets, or simply when the measured pressure exceeds the rated value, the free end of the elastic element is displaced, and the switch element is pushed directly or after comparison to change the on-off state of the switch element to control the measured pressure The purpose of stress. A pressure switch is a device combined with an electrical switch. When the preset fluid pressure is reached, the switch contact will act. It is mainl...
