Abstract
The utility model discloses an A-type constant pressure explosion valve device used for a hole packer of a coal mine pump drainage gas hole grouting airbag. The A-type constant pressure explosion valve device used for the hole packer of the coal mine pump drainage gas hole grouting airbag comprises an explosion valve base comprising a main pipe and a branch pipe, the branch pipe is perpendicular to the main pipe and is communicated with the main pipe, the outer wall of the branch pipe is provided with a thread and is provided with a nut in a screwed mode, and a membrane is arranged between the mouth portion of the branch pipe and the inner side of the nut. The A-type constant pressure explosion valve device used for the hole packer of the coal mine pump drainage gas hole grouting airbag is compact and firm in structure and is used in cooperation with the hole packer of the coal mine pump drainage gas hole grouting airbag, the membrane explodes when grouting pressure reaches a certain value, the flowing direction of fluid is changed, the A-type constant pressure explosion valve device is suitable for the mine underground pump drainage gas hole grouting airbag environment, the explosion pressure is stable, the explosion pressure errors are small, and interference from external temperature is small.
Description
Technical field
The utility model relates to a kind of colliery drawing-off gas hole slip casting pouch hole packer A type 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 A type level pressure explosive valve device, supporting colliery drawing-off gas hole slip casting pouch hole packer uses, in slip casting process, in the time that slip casting pouch pressure reaches certain value, can respond in time, explosion pressure release also changes slip casting direction, and pouch is by fully filling, to reach the object in shutoff gas hole.
The technical solution of the utility model is as follows:
A type level pressure explosive valve device for a kind of colliery drawing-off gas hole slip casting pouch hole packer, include explosive valve base, it is characterized in that: described explosive valve base includes supervisor and perpendicular to supervisor the arm that is connected with supervisor, the outer wall of described arm is provided with screw thread and is screwed with nut, between the oral area of arm and the inner side of described nut, is provided with diaphragm.
A type level pressure explosive valve device for described colliery drawing-off gas hole slip casting pouch hole packer, is characterized in that: the material of described diaphragm is metal or nonmetal.
The beneficial effects of the utility model:
The utility model compact conformation, firm, supporting colliery drawing-off gas hole slip casting pouch hole packer uses, in the time that grouting pressure reaches certain value, diaphragm explosion, change direction of flow, drawing-off gas hole slip casting pouch environment under suitable coal mine, and burst pressure is stable, burst pressure error is little, disturbed by ambient temperature little.
Brief description of the drawings
Fig. 1 is the structural representation of embodiment 1 in the utility model.
Fig. 2 is the structural representation of embodiment 2 in the utility model.
Detailed description of the invention
Referring to Fig. 1, A type level pressure explosive valve device for a kind of colliery drawing-off gas hole slip casting pouch hole packer, include explosive valve base, explosive valve base includes supervisor and perpendicular to supervisor the arm that is connected with supervisor, wherein supervisor adopts seamless steel pipe 4, and arm adopts hollow bolt 3, and the outside of hollow bolt 3 is screwed with nut 1, between the inner side of the oral area of hollow bolt 3 and nut 1, be provided with diaphragm 2, the material of diaphragm 2 is metal or nonmetal.
Referring to Fig. 2, A type level pressure explosive valve device for a kind of colliery drawing-off gas hole slip casting pouch hole packer, include explosive valve base, explosive valve base includes supervisor and perpendicular to supervisor the arm that is connected with supervisor, supervisor is connected and forms tee piece 5 with arm one, wherein the outer wall of arm is provided with screw thread and is screwed with nut 1, between the oral area of arm and the inner side of nut 1, is provided with diaphragm 2, and the material of diaphragm 2 is metal or nonmetal.
The utlity model has following characteristics:
1, after diaphragm explosion, can change slurry stream to;
2, compact conformation, firm, easily installs the narrow and small environment in suitable coal mine gas slip casting pump drainage hole;
3, burst pressure is stable, is subject to external interference little, influenced by ambient temperature little;
4, burst pressure error is within ± 10%.
