Special Rubber Hose Assembly of Coal Hydraulic Stand

1.Application

It is used in coal or rock in grouting,water injection and subsequent blocking.

2.Construction

The sealing is consisted by expansion high-pressure hose,safety valve,quick joints,steel pipe skeleton and so on.

3.Technical Specification

working pressure:5-8Mpa.

sealing range:45-120mm

applied range:It is used to transport mixed resin,water,cement and other media.

joint:M20×1.5

Our company can design and process the sealing according to usersˊactual plugging hole diameter.

4.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 expand to achieve sealing,then the safety value opens for water injection and grouting.After water injection and grouting,the only thing to do is 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 backflow of water or slurry in the boreholes of coal and rock.

2.Sealing contraction:Water as a pressure medium.It need suction pump,then compressed gas can be discharged from the supply pipe.
