Abstract

The invention discloses a pressure relay, relates to the technical field of relays, and solves the problems that when an existing pressure relay triggers an electric signal, the pressure of the pressure relay is inconvenient to adjust, the sensitivity is relatively low, the pressure relay cannot be suitable for various occasions, the practicability is relatively low, misoperation is caused when the pressure is unstable, and the operation safety of a circuit cannot be ensured. The relay comprises a relay shell; the upper part of the relay shell is rotationally connected with a group of pressure adjusting rotary handles; a group of central transmission supporting columns are connected in the relay shell in a sliding manner; the left side in the relay shell is rotationally connected with a group of connecting transmission shafts; the left side in the relay shell is rotationally connected with a group of electric shock transmission shafts; and a group of oil discharge plunger is slidably connected to the internal of the lower side of the right side of the relay shell. According to the invention, pressurization is carried out through the pressure spring, the middle transmission connecting plate moves, the movable contact is driven to be in contact with the static contact, triggering is carried out, and generation of an electric signal is realized.

Description

technical field [0001] The invention relates to the technical field of relays, in particular to a pressure relay. Background technique [0002] The pressure relay is a hydraulic-electric conversion element that uses the pressure of the liquid to open and close the electrical contacts; when the system pressure reaches the set value of the pressure relay, an electrical signal is sent to make the electrical components act, and the oil circuit is depressurized, reversed, and executed. The components realize sequential actions, or turn off the motor to stop the system from working, and play a role of safety protection. [0003] For example, the application number: 202010749014.9 The present invention discloses a new type of pressure relay, which includes a mounting case, the mounting case is a cuboid structure, and one side of the mounting case in the length direction is connected with an oil inlet pipe for hydraulic oil to flow into the mounting case. The installation housing i...
