Our inflatable packer products have five kinds: double inflatable packers, consolidation coal hole packer, water injection hole packer, gas drainage hole packer and water use of bottom hole circulation grouting plug.

A simple introduction of hole packers:

Water use of bottom hole circulation grouting plug is widely used in hydropower station, reservoir engineering curtain, consolidation, backfill, chemical grouting, geological exploration water pressure testing and water shutoff in drilling. And it is also used in the hole plugging and water shutoff of coal bed, gas testing and discharge. It can be used repeatedly for 30 - 50 times.

Water use of bottom hole circulation grouting plug has three holes: the first one is used to inject water or air into it to make the rubber hose inflated, the second one is used to inject cement and the third one is used to discharge the water or gas produced in the cement injection process.

Water injection hole packer is used to inject water to coal, which can reduce the gas content and dust. As a result, it can improve the safety coefficient of mine construction and production greatly. It is composed of high pressure inflation rubber hose, safety value and rapid-acting coupling. And it can be used repeatedly for 30 - 50 times.

Gas drainage hole packer has two holes: one is used to inject water to the coal bed, and another is used to discharge gas. So it has all the functions of water injection hole packer, such as reducing gas content, improving workers operation conditions, preventing coal auto-ignition and lowering cost. Besides, it can be used for gas drainage.
