Exhaust pressure relief device of vacuum equipment

Abstract

The invention discloses an exhaust pressure relief device of vacuum equipment. The equipment comprises vacuum equipment, the vacuum equipment is connected with a pressure relief pipe in a penetratingmode, pipe air outlet grooves are formed in the side walls of the front end and the rear end of the pressure relief pipe in a penetrating mode, a second threaded groove is formed in the inner wall ofthe pressure relief pipe, and the pressure relief pipe is in threaded connection with a threaded rod through the second threaded groove. The vacuum equipment has the beneficial effects that the adjusting handle and the threaded rod are matched with the second threaded groove in the pressure relief pipe for use, so that the vacuum equipment can perform pressure relief and exhaust work, and the operation is simple; during operation, through the arrangement of the two convex protection plates, gas rushing out of the pipe gas outlet groove of the pressure relief pipe and the fixing block gas outlet groove in the protection fixing block can be blocked, and potential safety hazards caused by impact on workers are avoided; and through the arrangement of the protective fixing block, the hidden danger that the pressure relief pipe is ejected out due to too large air pressure is avoided when the pressure relief pipe relieves pressure, and the pressure relief pipe can be effectively fixed and protected.

Description

technical field [0001] The invention relates to the field of vacuum equipment, in particular to an exhaust and pressure relief device for vacuum equipment. Background technique [0002] Some small vacuum equipment needs to meet the internal vacuum requirements when it is working, and it needs to discharge the pressure of the vacuum equipment when it is not working, and in the existing technology, the operation of many small vacuum equipment exhaust and pressure relief devices is quite Complicated, it is only suitable for large-scale vacuum equipment, not for small-scale vacuum equipment; the pressure relief rate of many exhaust and pressure relief mechanisms is slow, and during the process of exhaust and pressure relief, the gas flushed out of the vacuum equipment is very slow It is easy to cause harm to the nearby staff, and the hidden danger is relatively large. Contents of the invention [0003] The object of the present invention is to provide an exhaust and pressure ...
