Hengshui Jinggong Rubber & Plastic Products Co., Ltd.
. Use: Applicable to blocking holes on the coal or rock mass in the grouting, injection time and the subsequent
. Structure:
It consists of high pressure expanded hose, safety valve, quick connector and framework steel pipe.
. Technical Parameter:
Working Pressure: 58MPa
Sealing Hole Scope: 45mm120mm
Application Scope: Can transport mixed resin, water, cement and other media.
Connection: M20×1.5
Our company can design and process sealing hole implements according to customers actual plugging hole diameter.
. Application Method and Note:
1. Fast and easy use. Put it into the hole entirely and connect to the stressor, when the pressure rises up to 0.4Mpa, rubber hose expands absolutely and hole sealing is achieved, then safety valve is on, fill the coal body with water or grout. After effusion and grouting, remove the sphagnum connected with sealing hole counterclockwise, sealing hole implement still keeps expanded state in hole so that its long time blocking can be ensured effectively, moisture or serum in coal or rock mass doesnt have backflow.
2. Sealing hole implement shrinkage: When water is as pressure medium, sealing hole implement needs water suction pump. Compressed gas can be discharged through supply pipe.
Specification: Standard or according to customers requirements
Packing: carton or according to customers request
Note: we can arrange production under American Standard (ANSI), German Standard (DIN), Japanese Standard (JIS) and non-Standard.
