Abstract

The invention discloses a pipeline pressure relief device which comprises an explosion-proof membrane, a signal line, a feedback module, an air cylinder and a sealing cover; the explosion-proof membrane is sealed on an opening of a pipeline; one end of the signal line is arranged on the explosion-proof membrane, and is suitable for being broken when the explosion-proof membrane bursts; the feedback module is connected with the other end of the signal line; the air cylinder is connected with the feedback module; the feedback module is used for enabling the air cylinder to release pressure when the signal line is broken; the sealing cover is positioned above the opening; and the sealing cover is connected with the air cylinder, is pulled by the air cylinder to open the opening, and is moved to close the opening when the air cylinder releases pressure. According to the embodiment of the invention, the pipeline pressure relief device is good in pressure-relief performance, is simple and convenient to recover, is stable in operation, is low in fault rate and is high in safety reliability, can realize quick pressure relief and timely sealing after pressure relief, and quickly and stably guarantees that purified gas in the pipeline does not leaks outside, and outside gas enters.

Description

technical field [0001] The invention relates to a pipeline pressure relief device, which is applicable to poisonous and harmful gas pipelines and clean gas pipelines with strict requirements on air. Background technique [0002] The pipeline pressure relief device in the related art has a complicated structure, is easy to be damaged, and has a high replacement cost. At the same time, the opening of the pipeline cannot be closed in time after the pressure relief, resulting in the leakage of gas in the pipeline and the entry of external gas, and the damage of the pipeline pressure relief device. The structure could be improved. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, the present invention proposes a pipeline pressure relief device, which has good pressure relief performance, easy recovery, stable operation and low failure rate, and can realize rapid press...
