Description
Technical Field
The invention relates to the technical field of pressure switches, in particular to a copper pressure switch alarm.
Background
The pressure switch adopts a pressure sensor and a transmitting circuit with high precision and high stability, and then realizes the detection, display, alarm and control signal output of medium pressure signals through a special CPU modular signal processing technology. The pressure switch can be widely used for measuring and controlling the gauge pressure and absolute pressure of various gases and liquids in the fields of petroleum, chemical industry, metallurgy, electric power, water supply and the like, and is an ideal intelligent measuring and controlling instrument for industrial fields. At present, pressure switches and pressure alarms are not integrated in the market.
Disclosure of Invention
In view of the above-mentioned current state of the art, the technical problem to be solved by the present invention is to provide an alarm having both alarm and switch functions.
The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a copper pressure switch alarm, includes the body, body one end is equipped with the protecgulum, and the other end is equipped with the back lid, be equipped with the pull rod on the protecgulum, this pull rod backward extend to the back cover and this pull rod is arranged in the body outside, the body includes balanced piston and spring assembly, is equipped with the magnetic ring on this piston, piston outside cover has the instruction ring, and the cover has the hoop on this instruction ring, the spring assembly with the protecgulum offsets, be equipped with the reed pipe in the protecgulum, be equipped with the connection terminal on this reed pipe.
Furthermore, a cover body and a shielding cover are sequentially sleeved on the outer sides of the indicating ring and the iron ring from inside to outside and are used for protecting the indicating ring and the iron ring.
Furthermore, a guide pipe and a spring seat are arranged in the spring group and used for guiding the motion trail of the spring.
Furthermore, a sleeve is arranged in the front cover, and the reed pipe is arranged in the sleeve.
Furthermore, a socket base is arranged below the wire holder and is arranged above the front cover.
Further, a protective cap covers the wire holder.
Further, the spring group comprises a thin spring and a thick spring.
Furthermore, a diaphragm is arranged between the piston and the rear cover to play a role in sealing.
Compared with the prior art, the invention has the advantages that: the invention pushes the spring to simultaneously influence the reed pipe by the movement of the piston and the magnetic ring, so that the reed pipe is influenced by the magnetic force, and the wire holder sends out power-off action.
