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
The present invention relates to a kind of power supply pressure switch.
Background technology
Pressure switch adopts pressure sensor and the transmission circuit of high accuracy, high stable performance, then through dedicated cpu modular signal treatment technology, realizes the detection to pressure medium signal, display, warning and control signal and export.Pressure switch can be widely used in the fields such as oil, chemical industry, metallurgy, electric power, water supply the gauge pressure of various gas, liquid, the Survey control of absolute pressure, is the desirable intelligent measurement and control instrument of industry spot.
Pressure switch is when system internal pressure is higher or lower than specified safe pressure, in inductor, video disc is instantaneous is moved, be switched on or switched off by connecting guide rod pull switch joint, when Pressure Drop to or when rising specified recovery value, video disc instant reset, switch automatically resets, or be briefly when by measuring pressure overrate, the free end of flexible member produces displacement, directly or promote switch element after relatively, change the on off operating mode of switch element, reach and control by the object of measuring pressure.
Current existing power supply pressure switch construction less stable, install inconvenient, degree of regulation is lower.
Summary of the invention
It is reliable that the technical problem to be solved in the present invention is to provide a kind of Stability Analysis of Structures, and security performance is high, easy for installation, the power supply pressure switch that degree of regulation is high.
For solving the problem, the present invention adopts following technical scheme: a kind of power supply pressure switch, comprise upper cover, lower cover, threaded rod and piston, described upper cover is located at down and covers, described upper cover is threaded with lower cover, described threaded rod is located at and covers, described threaded rod is threaded with upper cover, described piston is located in upper cover, described piston and upper cover are slidably connected, Compress Spring is provided with in described piston, described piston is connected with threaded rod by Compress Spring, described threaded rod side is provided with binding post, contact is provided with bottom described binding post, described binding post is electrically connected by contact and piston, diaphragm and outlet terminal is provided with below described piston.
As preferably, described outlet terminal and piston are electrically connected, and facilitate circuit to connect unobstructed.
