Electric actuator with explosion-proof protection mechanism

Abstract

The invention provides an electric actuator with an explosion-proof protection mechanism, and belongs to the technical field of electric actuators. The electric actuator comprises a supporting bottomplate, wherein an explosion-proof mechanism is fixedly supported and installed on the side of the top part of the supporting bottom plate, the explosion-proof mechanism comprises an early warning detection box which is vertically supported and fixedly installed with the supporting bottom plate, a plurality of square exhaust holes are formed in the surface of the side wall of the early warning detection box, the surfaces of the square exhaust holes are connected with a plurality of circulating air outlet net covers in a covering mode, a PCB is installed in the early warning detection box, a temperature and humidity sensor and a flame detector are fixedly installed on the surface of the PCB in a supporting mode, and an explosion-proof mechanism is fixedly supported and mounted in the middleof the top end of each supporting bottom plate. In the daily use process, the explosion-proof mechanism and an explosion-proof box can achieve the good isolation and explosion-proof purposes on the electric actuator, a temperature and humidity sensor and a flame detector which are arranged in the early warning detection box are used for achieving spontaneous combustion when the internal temperature is high, and the temperature and humidity are detected by the temperature and humidity sensor and the flame detector.

Description

technical field [0001] The invention belongs to the technical field of electric actuators, and in particular relates to an electric actuator with a flameproof protection mechanism. Background technique [0002] The actuator is an essential and important part of the automatic control system. Its function is to accept the control signal sent by the controller, change the size of the controlled medium, so as to maintain the controlled variable at the required value or within a certain range. According to its energy form, actuators can be divided into three categories: pneumatic, hydraulic and electric. Pneumatic actuators use compressed air as an energy source, and are characterized by simple structure, reliable and stable action, large output thrust, convenient maintenance, fire and explosion protection, and low price, so they are widely used in chemical, papermaking, oil refining and other production processes. It can be conveniently used in conjunction with passive meters....
