Abstract
A liquid state and gas state pressurizing type gas hole packer comprises a drainage pipe and capsules. The liquid state and gas state pressurizing type gas hole packer is characterized in that the drainage pipe is sleeved with two or more capsules, an inflation pipe and a liquid filling pipe are positioned in the drainage pipe, the inflation pipe in the capsules is provided with gas filing ports, the liquid filling pipe between two capsules is provided with liquid filling ports penetrating out of the drainage pipe, the rear end of the drainage pipe is provided with a drainage parameter detection hole, and an inflation valve, an inflation pressure meter, a liquid filling valve, a liquid filling valve, a liquid filling pressure meter and a negative pressure meter are installed at the rear end of the drainage pipe. The front end of the drainage pipe is provided with an air inlet. According to the liquid state and gas state pressurizing type gas hole packer, hole sealing and drainage are integrated. The inflated capsules plug gaps between the drainage pipe and a hole wall, gaps between the inflated capsules and the hole wall and gaps of the hole wall (or a coal and rock mass) are plugged through liquid in a liquid filling chamber, communication between an external space and a gas chamber is cut off thoroughly, and accordingly the goal of only pumping gas and pumping no air is achieved. According to actual use, the preset goal is achieved, and the liquid state and gas state pressurizing type gas hole packer is suitable for the coal mining industry.
Description
Technical field
The present invention relates to Safety of Coal Mine Production technical field, relate in particular to liquid gas binary states pressurized type gas envelope
Hole device.
Background technology
The Main Ingredients and Appearance of gas is methane.It is a kind of clean energy resource, is again the major casualty in coal production process, the security of the lives and property that is greatly threatening staffs in coal mine, and the particularly serious accident overwhelming majority in colliery that the whole nation occurs for many years is caused by gas.Therefore, the improvement of gas and comprehensive utilization are more and more subject to the great attention of governments at all levels, safety regulator and enterprise.But in the improvement and Comprehensive Utilization of gas, traditional hole-sealing technology adopts cement mortar or the beautiful material sealing of hole such as loose of horse conventionally.After extraction Completion of Drilling Hole, in releasing pipe patchhole, clearance filled tight by between releasing pipe and hole wall of the sealing materials such as cement injection mortar (or horse beautiful loose), is then connected releasing pipe to carry out extraction with extraction pipe network.There are following two major defects in the method: the one, and the relief of the relief between sealing material and hole wall and hole wall (or in coal and rock) self is cannot shutoff tight, and while causing extraction, relief air inlet has reduced the gas density of drainage efficient and extraction; The 2nd, the releasing pipe in sealing material and the hole of nuzzling is disposable not reusable, wastes large cost high.
The impact of the factors such as the sealing of hole effect during due to gas drainage under suction is bad, and sealing of hole cost is higher, and extraction concentration is lower, causes gas control cost high, and effect is undesirable.The comprehensive subject matter existing in gas control and each link of comprehensive utilization of analyzing, wherein sealing of hole effect is bad, extraction concentration is low, sealing of hole cost height is a critical problem in problems.People have done improvement to gas hole packer for this reason, as Chinese patent ZL2012200026726.9 " exits formula gas hole packer " and ZL201120394451.x " a kind of Self-expansion type gas hole packer " etc., there is its certain effect, but all also have many deficiencies, fail to solve the major defect existing in traditional handicraft, this liquid gas binary states pressurized type gas hole packer is under this background and design.
Summary of the invention
It is bad that the purpose of this utility model is to overcome prior art sealing of hole effect, sealing of hole cost is higher, and the problem that extraction concentration is lower provides practical, effective a kind of liquid gas binary states pressurized type gas hole packer, to solve the defect existing in traditional handicraft, administer and comprehensive utilization gas.
To achieve these goals, the technical solution of the utility model is as follows: a kind of liquid gas binary states pressurized type gas hole packer, comprise releasing pipe, capsule, it is characterized in that being set with on described releasing pipe two or more capsules, in releasing pipe, there are gas tube and topping up pipe, in capsule, gas tube has inflation inlet, between two capsules, topping up pipe has the implementation of port that passes releasing pipe, in releasing pipe rear end, be equipped with extraction parameter detecting hole and charge valve, inflation gauge, prefill valve, liquid-filled pressure gauge and vacuum table are housed, at releasing pipe front end, having air inlet port.
It is integrated that the utility model has been realized sealing of hole extraction.By the capsule shutoff releasing pipe after inflation and the gap between hole wall, the relief of the capsule after heaving by the indoor liquid shutoff of fluid injection and the relief between hole wall and hole wall (or in coal and rock) self, thoroughly cut off space outerpace and gas Shi UNICOM, thereby reach the not object of exhaust of a gas pumping.The quantity of capsule and fluid injection chamber, selected according to field condition.
Advantage of the present utility model:
1, solved the effectively problem of the relief between shutoff sealing material and hole wall and hole wall (or in coal and rock) self relief of existing hole-sealing technology, thoroughly cut off space outerpace and gas Shi UNICOM, drainage efficient and extraction concentration have been improved, for advantage has been created in Achievements of Gas Control and comprehensive gas utilization;
2, can be used as the use that draws out methane and measure coal-bed gas pressure sealing of hole;
3, can be repeatedly used, execute-in-place simple and fast, has saved manpower and materials, has greatly reduced sealing of hole cost;
4, without any potential safety hazard.
The liquid gas binary states pressurized type gas hole packer that the utility model provides, is used proof by reality, has reached predetermined object, is applicable to coal mining industries.
