Abstract

The invention discloses a power supply pressure switch. The power supply pressure switch comprises an upper cover, a lower cover, a threaded rod and a piston, wherein the upper cover is arranged on the lower cover; the upper cover and the lower cover are in threaded connection; the threaded rod is arranged on the upper cover; the threaded rod and the upper cover are in threaded connection; the piston is arranged in the upper cover; the piston is glidingly connected with the upper cover; a compression spring is arranged in the piston; the piston is connected with the threaded rod through the compression spring; a wiring terminal is arranged on one side of the threaded rod; a contact is arranged at the bottom of the wiring terminal; the wiring terminal is electrically connected with the piston through the contact; and a diaphragm and a wire-outlet terminal are arranged below the piston. The power supply pressure switch is stable and reliable in structure, high in safety performance, convenient to adjust and high in adjustment precision.

Description

technical field [0001] The invention relates to a power supply pressure switch. Background technique [0002] The pressure switch adopts a high-precision, high-stability pressure sensor and transmission circuit, and then uses a dedicated CPU modular signal processing technology to realize the detection, display, alarm and control signal output of the medium pressure signal. The pressure switch can be widely used in petroleum, chemical industry, metallurgy, electric power, water supply and other fields to measure and control the gauge pressure and absolute pressure of various gases and liquids. It is an ideal intelligent measurement and control instrument for industrial sites. [0003] The pressure switch is when the pressure in the system is higher or lower than the rated safety pressure, the disc in the sensor moves instantaneously, and the switch joint is connected or disconnected by connecting the guide rod, and when the pressure drops or rises to the rated recovery value...
