Abstract
The utility model discloses a valve non-welding sealing flange which comprises a flange plate. A through hole is formed in the middle portion of the flange plate, step grooves are formed all around the through hole, flat gaskets are arranged on the bottoms of the step grooves, pressure check rings are arranged inside the step grooves, spring holes are formed in the lateral walls of the step grooves, springs are arranged inside the spring holes, and bolts holes are formed all around the edge of the flange plate. The valve non-welding sealing flange is firm in connection and good in sealing effect.
Description
Technical field
The utility model relates to a kind of valve welding sealing flange.
Background technique
In the existing technology, valve welding sealing flange is widely used in the pipeline industry, but in general pipeline connection procedure, if pipeline does not arrange flange in advance, just is difficult to connect, and so just is difficult to connect, and occurs easily leaking.
