1. use:

is suitable for plugging holes in coal or rock mass during grouting, water injection and thereafter.

2. structure:

hole sealer consists of high-pressure expansion hose, safety valve, quick connector and skeleton steel pipe.

3. Technical Parameters:

Working Pressure: 5-BMPa Sealing Range: 45mm-120mm

Application Range: Conveyable Mixed Resin, Water, Cement and Other Media

Connection: M20 × 1.5

The Company can design and process the sealer according to the actual plugging diameter of the user.

4. Usage:

. It is quick and simple to use the hole sealer. Insert the hole sealer completely into the borehole, connect the hole sealer with the pressure source, start the pressure, and when the pressure is raised to 4MPa, the hose is completely expanded to seal the hole. At this time, the safety valve is opened, and water or slurry is injected into the coal body. After water injection or grouting is completed, only the connecting pipe connected with the hole sealer needs to be rotated out counterclockwise, and the hole sealer still maintains an expanded state in the borehole to achieve long-term blocking, which can effectively ensure the occurrence of water or slurry backflow in the coal or rock borehole.

2. Contraction of the hole sealer: When water is used as the pressure medium, a suction pump is required; compressed gas can be discharged from the supply pipe.
