Title:
HIGH-PRESSURE DIAPHRAGM COMPRESSOR AND CYLINDER COVER THEREOF, AND MACHINING METHOD FOR CYLINDER COVER
Document Type and Number:
WIPO Patent Application WO/2020/052050
Kind Code:
A1
Abstract:
A high-pressure diaphragm compressor and a cylinder cover thereof, and a machining method for the cylinder cover, comprising a cylinder cover body (10). The cylinder cover body (10) is provided with an exhaust valve (5), an exhaust hole blockage (1), and an exhaust cavity (13), an area where exhaust holes are formed in the center of the cylinder cover (01) is excavated to serve as the exhaust cavity (13), and the exhaust hole blockage (1) is independently mounted in the exhaust cavity (13); a corrugated spring (2) is provided between the exhaust hole blockage (1) and an exhaust valve (5); the exhaust hole blockage (1) can be used for machining a diaphragm cavity profile of the diaphragm compressor together with the cylinder cover (01) only after being mounted on the cylinder cover (01) well; the outer diameter of the exhaust hole blockage (1) is less than the inner diameter of the exhaust cavity (13). By means of the structure, the problems that under the conditions of high temperature and high pressure, due to the structural limitation of the exhaust holes, deformation of the exhaust holes is greatly constrained, and full expansion cannot be achieved, and thus the thermal stress of the inner surfaces of small holes is quite large are solved; the thermal stress generated by the exhaust holes due to high temperature can be reduced, and thus the strength of the cylinder cover of the high-pressure diaphragm compressor is increased, without affecting normal operation of the diaphragm compressor.
