Abstract
The utility model discloses a B-type constant-pressure explosion valve device for a slurry injection bag hole sealing device for a gas discharging hole of a coal mine. The B-type constant-pressure explosion valve device comprises a slurry injection pipe, explosion holes are formed in the wall of the slurry injection pipe, the slurry injection pipe is sleeved with an explosion pipe wrapping the explosion holes, and locking hoops are tightly pressed on the outsides of the two ends of the explosion pipe in a sealed mode. The B-type constant-pressure explosion valve device is compact in structure, easy and convenient to machine, low in material cost, high in performance cost ratio and capable of being used in cooperation with the slurry injection bag hole sealing device for the gas discharging hole of the coal mine. In a slurry injection process, when slurry injection pressure reaches a certain value, timely response can be achieved, the explosion pipe explodes, the flow direction of cement slurry is changed, bags are filled in good condition, a hole between the two bags is blocked through slurry injection, the purpose of gas blocking is achieved, and the B-type constant-pressure explosion valve device is suitable for a slurry injection environment of the gas discharging hole of the underground coal mine.
Description
Technical field
The utility model relates to a kind of colliery drawing-off gas hole slip casting pouch hole packer Type B level pressure explosive valve device.
Background technology
Mash gas extraction is the important process of administering gas in mine operation, in mash gas extraction process, need to ensure that borehole sealing is tight, and sealing of hole effect quality is the key of gas pumping.Existing " two stifled notes " injection hole sealing technique with pressure, after one of its key is that two is blocked up in fact, can be to interlude slip casting, the quality of hole packer explosive valve device is the key in gas pumping key.
The problem points of existing hole packer explosive valve device is: the accuracy of explosive valve blasting time is difficult to control.Morning blasting time, two pouch can not fill cement paste completely, affects interlude slip casting effect; In evening blasting time, pouch inner grouting pressure in two is excessive, likely bursts pouch, causes sealing of hole failure.
Utility model content
The purpose of this utility model is to provide a kind of colliery drawing-off gas hole slip casting pouch hole packer Type B level pressure explosive valve device, supporting colliery drawing-off gas slip casting pouch hole packer uses, in slip casting process, in the time that grouting pressure reaches certain value, can respond in time blasting cartridge explosion, changing cement paste flows to, pouch filling is full intact, and slip casting shutoff in hole between two pouches, to reach the object of shutoff gas.
The technical solution of the utility model is as follows:
Type B level pressure explosive valve device for a kind of colliery drawing-off gas hole slip casting pouch hole packer, include Grouting Pipe, it is characterized in that: the tube wall of described Grouting Pipe is provided with shot hole, the outer cover of Grouting Pipe has the blasting cartridge in described shot hole is wrapped in, and the outside at described blasting cartridge two ends compresses respectively and be sealed with locking clip.
Type B level pressure explosive valve device for described colliery drawing-off gas hole slip casting pouch hole packer, is characterized in that: described blasting cartridge is rubber tube or metal tube.
The beneficial effects of the utility model:
The utility model compact conformation, process easy, lower cost for material, cost performance is high, and supporting colliery drawing-off gas slip casting pouch hole packer uses, in slip casting process, in the time that grouting pressure reaches certain value, can respond in time, blasting cartridge explosion, has changed the cement paste flow direction, pouch filling is full intact, slip casting shutoff in hole between two pouches, has reached the object of shutoff gas, slip casting environment in drawing-off gas hole under suitable coal mine.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Referring to Fig. 1, Type B level pressure explosive valve device for a kind of colliery drawing-off gas hole slip casting pouch hole packer, include Grouting Pipe 3, the tube wall of Grouting Pipe 3 is provided with shot hole 1, the outer cover of Grouting Pipe 3 has the blasting cartridge 2 in shot hole 1 is wrapped in, and the outside at blasting cartridge 2 two ends compresses respectively and be sealed with locking clip 4.
In the utility model, blasting cartridge 2 is rubber tube or metal tube.
Burst pressure error of the present utility model is within ± 20%.
