The vacuum flange should have sufficient strength and should not deform when tightened. The flange sealing surface should be flat and clean, and oil stains and rust spots should be carefully cleaned during installation.
The sealing gasket shall have good oil resistance and aging resistance, as well as good elasticity and mechanical strength. Installation should select sealing gaskets of different cross-sections and sizes according to the shape of the connection, and place them correctly.
The flange fastening force should be uniform and consistent, and the compression amount of the gasket should be controlled at about 1/3.
What is the difference between flanges and valves?
Valves are like faucets, or in other words, faucets are a type of valve. You can unscrew it, and water or gas can flow out; You can close it, and the water won't flow anymore.
The water tap at home is threaded onto a pipe, but some pipes used in factories have high water or gas pressure inside, and threaded connections are too weak, so they are directly welded or connected by other methods. Flanges are one of the connection methods.
