Description

Technical Field

[0001] The utility model relates to the technical field of flange detection, in particular to a flange leakage detection tool. Background Art

[0002] As ring main units are used in more and more areas of projects, in order for the products to meet the maintenance-free requirements, the reliability of key parts used in the products is very important. Sealing flanges are also widely used in products. When installing the sealing flange on the gas box, it is necessary to ensure that the flange sealing performance meets the technical process requirements. Therefore, it is very necessary to make sealing flange sealing inspection tooling.

[0003] The sealing flanges on existing ring main units cannot be judged for sealing after they are returned. After the size inspection, they are directly installed on the gas box products. If the gas box leaks, the flange needs to be reworked and replaced, resulting in a large workload, low production efficiency, and affecting product stability. The leakage detection equipment for sealing flanges on the market is currently complex and troublesome to operate, and it will increase the cost of the enterprise, which is not conducive to market promotion. Utility Model Content

[0004] The utility model aims to provide a flange leak detection tool to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flange leak detection tool, comprising a flange mounting plate, one side of the flange mounting plate is sealed and connected to an air box, the flange mounting plate is provided with a flange mounting hole, a pressure gauge mounting hole and a self-sealing valve mounting hole, the pressure gauge mounting hole is connected to a pressure gauge, the self-sealing valve mounting hole is installed with a self-sealing valve, and flange fixing studs are provided around the flange mounting hole.

[0006] Preferably, the number of the flange mounting holes is two.

[0007] Preferably, openings are provided at both ends of the flange mounting plate.

[0008] Compared with the prior art, the utility model has the following beneficial effects: the utility model can detect the sealing of the flange by setting a flange mounting plate and an air box and inflating the air box, and has a simple structure, convenient operation and high detection efficiency.
