During the production process of fire-fighting pipes, corresponding air-tightness testing equipment is required to perform sealing tests on the fire-fighting pipes. Air-tightness testing equipment is also called air-tightness tester. Air-tightness tester is mainly used for sealing tests of packaging bags, bottles, tubes, cans, boxes, etc.
[0003] The following testing equipment is used in air tightness testing equipment: Usually, both ends of the fire protection pipe are blocked to form a closed cavity in the pipe.

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0017] like Figure 1-Figure 3As shown, a fire protection pipe air tightness detection equipment includes a circular platform 1, and a controller 2 is fixedly installed on one side of the circular platform 1. It is characterized in that: an electric push rod 8 is fixedly installed on the internal top of the circular platform 1, and a sealing gasket 2 is fixedly installed on the lower end of the electric push rod 8. A high-pressure air pump 10 is fixedly installed on the upper end of the circular platform 1, and the air outlet of the high-pressure air pump 10 is connected to an air guide hose 11, and the air guide hose 11 passes through the interior of the sealing gasket 2 19. A transparent box 3 is fixedly installed on the internal upper end of the circular platform 1, and a sealing gasket 18 is fixedly installed on the internal bottom end of the transparent box 3. A pipe to be tested 17 is arranged above the sealing gasket 18, a fixing plate 9 is fixedly installed on one side of the upper end of the circular platform 1 close to the transparent box 3, and a water tank 4 is fixedly installed on the other side of the upper end of the circular platform 1 close to the transparent box 3, and the upper end of the water tank 4 is connected to a water inlet pipe 5. Conduit 1 6 and conduit 2 7 are connected between the water tank 4 and the transparent box 3 , and conduit 1 6 supplies water to the transparent box 3 , and conduit 2 7 pumps water out of the transparent box 3 , and one end of conduit 1 6 and conduit 2 7 are both connected to a water pump, which is located inside the transparent box 3 .
[0018] First, place the pipe 17 to be tested on the upper end of the sealing gasket 18 inside the transparent box 3, start the electric push rod 8, and make the sealing gasket 2 19 at the lower end of the electric push rod 8 fit the upper end of the pipe 17 to complete the sealing of both ends of the pipe 17 to be tested. At this time, inject an appropriate amount of water into the transparent box 3 through the conduit 2 7 to submerge the pipe 17 to be tested, and then start the high-pressure air pump 10. The high-pressure gas generated by the high-pressure air pump 10 passes through the air guide hose 11 and then through the sealing gasket 2 19 and is injected into the interior of the pipe 17 to be tested. When there are holes on the surface of the pipe 17 to be tested, bubbles will be generated on the surface of the pipe 17 to be tested, indicating that the pipe 17 to be tested is unqualified, otherwise it is qualified.
[0019] An L-shaped groove 12 is provided on one side of the fixing plate 9, a fixing block 13 is provided on one side of the fixing plate 9, a spotlight 14 is fixedly installed on the outside of the fixing block 13, an L-shaped plate 15 is fixedly installed on one side of the fixing block 13, the L-shaped plate 15 is movably engaged with the L-shaped groove 12, and a scale line 16 is engraved on the outside of the fixing plate 9.
[0020] When bubbles are observed outside the transparent box 3, the fixed block 13 is manually slid to illuminate the point where the bubbles originate, and the scale on the surface of the scale line 16 on the fixed plate 9 is read. When the pipe to be tested 17 is taken out, the location of the leak can be found immediately and repaired later, which is more convenient.
[0021] The implementation principle of the fire protection pipeline air tightness detection device of the embodiment of the present application is as follows: first, the pipeline to be tested 17 is placed on the upper end of the sealing gasket 18 inside the transparent box 3, and the electric push rod 8 is started to make the sealing gasket 2 19 at the lower end of the electric push rod 8 fit the upper end of the pipeline to be tested 17 to complete the sealing of both ends of the pipeline to be tested 17. At this time, an appropriate amount of water is injected into the transparent box 3 through the conduit 2 7 to submerge the pipeline to be tested 17, and then the high-pressure air pump 10 is started. The high-pressure gas generated by the high-pressure air pump 10 is passed through the air guide soft Tube 11, then through the sealing gasket 19, injected into the interior of the pipe to be tested 17, when there are holes on the surface of the pipe to be tested 17, bubbles will be generated on the surface of the pipe to be tested 17, indicating that the pipe to be tested 17 is unqualified, otherwise it is qualified. When bubbles are observed outside the transparent box 3, the fixed block 13 is manually slid to make the spotlight 14 illuminate the point where the bubbles are emitted, and the scale on the surface of the scale line 16 on the fixed plate 9 is read. When the pipe to be tested 17 is taken out, the location of the leak can be found in the first time, and it is more convenient to carry out later repairs.
