Explosion-proof electric control hydraulic actuating mechanism and working method thereof

Abstract

The invention discloses an explosion-proof electric control hydraulic actuating mechanism and a working method thereof. A mounting cavity is formed in a protection box, a first sealing gasket is fixedly connected to the inner wall of the mounting cavity, a mounting base is fixedly connected to the bottom of the mounting cavity, a first mounting hole is formed in the middle of the bottom surface ofthe mounting cavity, a hydraulic pipe is fixedly mounted in the first mounting hole, a first sealing groove is formed in the bottom of the mounting base, the first sealing groove is communicated withthe top end of the hydraulic pipe, four first through holes are formed in the top of the first sealing groove, every two of the four first through holes are symmetrically formed about the transversecenter line of the mounting base, and after the above structure is adopted, the electric control hydraulic actuating mechanism can prevent gas leakage and explosion in time through a first hydraulic mechanism and a second hydraulic mechanism, warn related personnel through an arranged alarm, release carbon dioxide gas in time, reduce the gas concentration and avoid dangers.

Description

technical field [0001] The invention relates to the technical field of electronically controlled hydraulic actuators, in particular to an explosion-proof electronically controlled hydraulic actuator. Background technique [0002] During the transportation of natural gas, it needs to go through a certain exchange station for depressurization or boosting or other operations. During this process, due to equipment errors, gas leakage may be caused, which in turn creates danger. However, the existing structure of the workstation , although the natural gas can be closed and prevented very well, there are no good protective measures, so that the device still has certain safety hazards, and the gas dilution cannot be performed in time to prevent danger. Contents of the invention [0003] In order to overcome the above-mentioned technical problems, the object of the present invention is to provide an explosion-proof electronically controlled hydraulic actuator, which prevents the l...
