Unlike the traditional method of stopping the line to replace the gasket, the utility model uses a detachable sealing container installed outside the leaking point to achieve the effect of emergency leak repair. The workshop does not need to stop the line and will not affect production. The utility model can also be applied to the leaking points that do not affect production mentioned in the background technology, thereby saving the electricity cost of the air compressor.
[0034] The first sealing portion 1 is provided with a first connecting plate 5 on the outer wall thereof, the first connecting plate 5 being located at the bottom of the first sealing portion 1. The second connecting plate 6 is provided on the outer wall of the second sealing portion 2, the second connecting plate 6 being located at the top of the second sealing portion 2. The first sealing member 3 is located between the first connecting plate 5 and the second connecting plate 6.

The provision of the first connecting plate 5 and the second connecting plate 6 facilitates the installation of the first sealing portion 1 and the second sealing portion 2. The screw and nut connection method is simple in structure and can also adjust the sealing performance. To increase the pressure resistance, the first sealing portion 1 and the second sealing portion 2 are typically made of 304 stainless steel and have a thickness of not less than 6 mm. To prevent deformation of the first and second connecting plates 5, 6 during prolonged use, the top surface of the first connecting plate 5 is provided with several first ribs 7 connected to the outer wall of the first sealing portion 1, and the bottom surface of the second connecting plate 6 is provided with several second ribs 8 connected to the outer wall of the second sealing portion 2 to reinforce the two connecting plates. Typically, there are 16 first ribs 7 and 16 second ribs 8 each. For ease of use, the first sealing portion 1 is typically a cube with an open bottom, with the first connecting plate 5 located at the bottom opening. The second sealing portion 2 is typically a cube with an open top, with the second connecting plate 6 located at the top opening. The box structure reduces the manufacturing difficulty of the device and facilitates storage. The bottom of the first sealing portion 1 is provided with a first half-hole adapted to the pipe radius, and the top of the second sealing portion 2 is provided with a second half-hole adapted to the pipe radius.

The first sealing member 3, the second sealing member 9 and the third sealing member 10 are usually rubber pads with a thickness of not less than 0.5 cm.
[0035] When the leak position of the pipeline is at the front end of the valve 100, as shown in FIG. Figure 1As shown, the valve 100 of the leaking pipe can be directly placed in the sealed space for emergency sealing. According to usage needs, if it is desired to control the valve 100 while plugging the leak, a transmission device 11 can be provided on the first sealing part 1. The transmission device 11 is sealed and movably connected to the first sealing part 1 to ensure that the two can rotate or slide relative to each other under the premise of ensuring sealing, and one end of the transmission device 11 is located outside the sealed space, and the other end passes through and extends into the first sealing part 1 to be connected to the valve 100, so that when the valve 100 needs to be controlled, it is only necessary to operate the transmission device 11. The transmission device 11 can be a connecting rod structure or any existing technology that can achieve a connecting rod effect.
