Problems solved by technology

[0003] The common method to deal with the leakage of flange seal is clamp plugging, but the general enterprise adopts a full circle structure composed of two equal parts, each part corresponds to a piece of flange, wraps it, and then injects the injection agent. This method first needs to consider the method The coaxiality of the flange, if the deviation of the coaxiality of the flange is relatively large, the operation of plugging will be very difficult, and due to the uneven force, the consumption of injection agent is large, the duration of plugging is short, and the effect is not good; and The cost of steel is twice as much as the new method

Embodiment Construction

[0014] Such as figure 1 As shown, the flange plugging fixture includes a fixture body 1 that is a semicircular strip, and three injection tubes 2 pass through the fixture body 1. One end of the injection tube 2 is a glue injection head 5 and the other end can be screwed into an injection nut 3. The clamp body 1 is provided with a connecting ring 4; the clamp body 1 is made of rubber.

[0015] Such as figure 2 , image 3 As shown, the fixture body 1 of the flange plugging fixture is close to the flange 6, the injection head 5 extends into the gap between the clips of the flange 6, the injection nut 4 is screwed into the injection tube 2, and passes through the tight fixture The connecting ring 4 on the body 1 penetrates the bolts and fastens on the flange 6 with nuts, the bolt holes 7 of the flange 6, the main pipe 8 is the connecting pipe of the flange 6, and gaskets 9 are arranged between the clips of the flange 6.

[0016] Working principle: When in use, the fixture body...

Abstract

A flange leaking stoppage fixture comprises an arc-shaped fixture body. Sealant injecting pipes are uniformly distributed on the arch back of the fixture body and extend out of the fixture body through sealant injecting nozzles, and sealant injecting nuts can be screwed to the sealant injecting pipes. The flange leaking stoppage fixture has the advantages of simple structure and convenience in use, and can be used for handling of the flanges with high deviation of concentricity.

Description

technical field [0001] The invention relates to a flange plugging fixture, which is especially suitable for sealing leakage of flanges in chemical processing. Background technique [0002] Leakage of pipeline flange seals is a common problem in chemical companies, especially the leakage of pressure pipelines and toxic and harmful media is a major hazard to people and the environment. Therefore, it can be solved in a timely manner without affecting chemical production. Leakage is a difficult problem for many chemical companies. [0003] The common method to deal with the leakage of flange seal is clamp plugging, but the general enterprise adopts a full circle structure composed of two equal parts, each part corresponds to a piece of flange, wraps it, and then injects the injection agent. This method first needs to consider the method The coaxiality of the flange, if the deviation of the coaxiality of the flange is relatively large, the operation of plugging will be very diff...
