Description

Technical Field

[0001] The utility model relates to the technical field of flange rings, in particular to a dustproof flange ring for a water ring vacuum pump. Background Art

[0002] Flange, also known as flange flange or flange, is a part that connects shafts to each other and is used to connect pipe ends; it is also used in the inlet and outlet of equipment for the connection between two devices, such as reducer flange. Flange connection or flange joint refers to a detachable connection composed of flange, gasket and bolts as a combined sealing structure. Pipe flange refers to the flange used for piping in pipeline installations. It is used on equipment to refer to the inlet and outlet flanges of the equipment. There are holes on the flange, and the bolts connect the two flanges tightly. The flanges are sealed with gaskets. Flanges are divided into threaded connection (threaded connection) flanges, welding flanges and clamping flanges.

[0003] When existing vacuum pumps are used and connected, flanges are often required to be used as intermediate auxiliary work. However, since the structure of ordinary flanges is relatively simple, and the flanges made of high-hardness materials will affect the installation work due to the excessive overall mass, an auxiliary structure is needed to perform a certain degree of reinforcement without affecting the stability of flange installation to avoid unnecessary loss.
