Gas drainage multi-functional sealed inflatable packer

structure:
The drainage gas multi-function sealing device consists of high-pressure ball valve, hose, expansion hose, sliding body pumping core tube composition.

Scope of application: Used for draining gas and coal water injection

1. Hole diameter 75mm, the maximum diameter of 128mm after expansion, pumping core tube diameter up to 35mm

2.Work pressure 1-15a

3. Hose expansion coefficient of 70% -90%

4. Suitable aperture 80mm-100mm

Drainage gas multi-function sealing device consists of high pressure ball valve, high pressure hose, expansion hose, sliding body, core tube. When used, the underground hydrostatic water pipe is connected to the high-pressure ball valve of the plugging hole, the expansion of the plugging hole expands rapidly, the hole is closed, and the straight-through drainage gas of φ25 is connected by a pipe. After the completion of the operation, disconnect the inlet pipe, open the high-pressure ball valve, release the water inside the sealer, expand the body to restore the original state automatically, withdraw from the hole, organize spare
