The invention discloses a pressure relief device at a drain outlet of a pneumatic diaphragm pump and relates to the technical field of construction devices of mining engineering. The pressure relief device comprises an air pump (1), a liquid inlet pipeline (3), a liquid inlet (2), a spherical stop valve (6), a water rope straight joint (7), a drain outlet (4) and a drain pipeline (5). The spherical stop valve and the water rope straight joint are connected to the drain outlet by welding. The pressure relief device has the beneficial effects that it can be known from the scheme that when the pressure is built at the drain outlet pipeline, the pressure of the drain outlet pipeline can be directly relieved from the spherical stop valve, so that the air pump works normally. The pressure relief device provided by the invention is simple in structure, skillful in design, good in using effect and time-saving and labor-saving, and meanwhile, the mechanical damage of the air pump which is detached is reduced, the service life of the air pump is prolonged, and the pressure relief device is popularized and applied conveniently.
Description
technical field [0001] The invention relates to the technical field of mining engineering construction devices, in particular to a pressure relief device for a discharge port of a pneumatic diaphragm pump. Background technique [0002] The air pump is a commonly used underground drainage equipment. During the use of the air pump, the discharge outlet pipeline is easy to hold pressure, causing the air pump to not work normally. If this device is not added, because the discharge port pipeline is always under pressure, it is very difficult to disassemble, which brings great inconvenience to maintenance work, affects normal drainage, and causes great difficulties to the work of the electromechanical maintenance team. [0003] Before setting up this invention, it is necessary to unload the drain outlet pipeline to remove the pressure held in the drain outlet pipeline. At this time, due to the excessive pressure of the discharge port, disassembly is very difficult, time-consuming...
