Abstract

The invention is applicable to the technical field of alarm devices, and provides a gas pipeline pressure relief alarm device. The gas pipeline pressure relief alarm device comprises a pressure reliefshell arranged on a conveying pipe in a communicating manner, wherein an embedded cavity is formed in the pressure relief shell, and an exhaust port is formed in the side wall of the pressure reliefshell; a sealing plug nested in the embedded cavity in a liftable manner and matched with the embedded cavity to form a sealing structure; a nut arranged in the embedded cavity in a sliding manner androtationally connected with the sealing plug through a spring; a lead screw which is rotationally connected to the pressure relief shell and penetrates through the nut in a matched mode, wherein thenut is rotated and adjusted through the lead screw to extrude the spring to adjust the extrusion force, and therefore the pressure relief pressure is controlled; a warning whistle arranged in the exhaust port and used for generating an alarm by utilizing airflow; an indicating lamp used for emitting a warning light source; a power generation assembly which converts rotational kinetic energy into electric energy and is electrically connected with the indicating lamp; and rotating blades connected with the power generation assembly. The gas pipeline pressure relief alarm device has the advantages of a simple structure, energy conservation, low production cost, strong warning capability and avoidance of electric energy dependence.

Description

Technical field[0001]The invention belongs to the technical field of alarms, and particularly relates to a gas pipeline pressure relief alarm device.Background technique[0002]In the process of chemical production or natural gas transportation, the transportation of high-pressure gas is mostly carried by pipelines, and alarms are often used on the pipelines to alert them to avoid pipeline explosions caused by high pressure. An alarm is an electronic product that reminds or warns us that we should take certain actions in the form of sound, light, air pressure, etc., in order to prevent or prevent the consequences caused by an event. Divided into mechanical alarm and electronic alarm. With the advancement of science and technology, mechanical alarms are increasingly replaced by advanced electronic alarms. They are often used in the fields of system failures, safety precautions, transportation, medical rescue, emergency response, induction detection, etc., and are closely related to soc...
