In the process of use, large flange pipe fittings may leak due to improper connection of large flange fittings or long use time. In this case, the problem can be solved in the following ways.

Check the leak part first. In the leak part, because the large flange pipe fitting is very small, the leak may be eliminated by injecting sealant into the leak place. Sealing construction method according to the leak site survey, in order to complete the limited plugging, the selection of a fixed fixture method to contain the leak point to form a sealing chamber, inject sealant, and then eliminate the leak. The fixture on one side is customized. The fixture should meet the leakage point of large flange fittings, and the sealing cavity between the large flange fittings of the valve body and the large flange fittings of the pipeline is the key. In order to prevent the potential leakage of the valve body and the large flange pipe fittings from appearing again due to the pressure holding, the ring cavity glue is set at the outer edge of the clamp and the large flange pipe fittings of the valve body. Because the jig tends to shift to the side of the small-diameter large flange pipe in the process of injection, the limit method of tooth contact clamping is selected. At the time of operation, after the sealant solidification, through the observation of the role, part of the filling pressure, to prevent the stress lax, and then close the injection hole.
