Boring Self-styled Sealing-JZF Ⅱ
Technical Specification
working pressure: 5~8Mpa sealing range: 45mm~120mm
applied range: It is used to transport mixed resin, water, cement and other media. joint: M20 x 1.5
Our company can design and process the sealing according to users' actual plugging hole diameter.
Usage
1.It is quick and easy to use the sealing. The sealing is fully inserted into the boreholes, connected with the pressure source, then starting pressure. When it reaches 0.4Mpa, the hose will be expanded to achieve sealing, then the safety valve opens for water injection and grouting. After water injection and grouting, the only thing to do is to spin out the hose connected with the sealing clockwise, now, the sealing is still in the boreholes to maintain the state of expansion a long time, which can effectively guarantee to avoid the back of water or slurry in the boreholes of coal and rock.
2.Sealing contraction: Water as a pressure medium, It need use suction pump, then compressed gas can be discharged from the supply pipe.
