Abstract
The invention discloses a self-expanding gas hole sealer. The hole sealer comprises a pumping pipe, wherein at least one elastic expansion sleeve is continuously locked and hooped on the pumping pipe; crushed inner sleeve bags are fixedly arranged on two sides of the pumping pipe in each elastic expansion sleeve in a sealed mode; chemical expansion liquid is filled among the elastic expansion sleeve, each inner sleeve bag and the pumping pipe; a reaction medium which can react with the chemical expansion liquid to quick expand is filled in a cavity between each inner sleeve bag and the pumping pipe; and the chemical expansion liquid is one kind of liquid polyurethane, and the reaction medium is water or air or the other kind of liquid polyurethane. The self-expanding gas hole sealer has the advantages of simple structure and low cost and is convenient to use.
Description
Technical field:
The present invention relates to the mine gas discharging, particularly a kind of self-expanding gas hole packer simple in structure, easy to use.
Background technology:
Existing disposable gas exhaust sealing of hole is that a releasing pipe is inserted in the gas extraction hole, then with cement mortar or polyurethane, uses special-purpose grouting equipment to press to annotate and carries out shutoff in the extraction hole.This method is time-consuming, and the effort use cost is high, and production efficiency is low.
Summary of the invention:
The purpose of this invention is to provide a kind of simple in structure, easy to use, automaticity is high, cost is low self-expanding gas hole packer.
Technical scheme of the present invention is accomplished as follows; It comprises a pump drainage pipe; It is characterized in that: locking clip has at least one elastic expansion cover continuously on the pump drainage pipe; Pump drainage Guan Shangcong both sides in each elastic expansion cover are sealed respectively and are fixed with one and crush bagging in the formula, elastic expansion overlap and interior bagging and pump drainage pipe between be incorporated with a kind of chemically expansible liquid, be incorporated with in the cavity between interior bagging and pump drainage pipe can with the react reaction medium of rapid expanding of chemically expansible liquid.Chemically expansible liquid is a kind of liquid polyurethane, and reaction medium is water or air or another kind of liquid polyurethane.The advantage that the present invention has is simple in structure, easy to use, cost is low.
Description of drawings:
Accompanying drawing is a kind of structural representation of the present invention.
The specific embodiment:
Describe embodiment in detail in conjunction with accompanying drawing.The present invention is that continuous locking clip has at least one elastic expansion cover 2 on a pump drainage pipe 1; Pump drainage Guan Shangcong both sides in each elastic expansion cover are sealed respectively and are fixed with one and crush bagging 3 in the formula; Between elastic expansion cover and interior bagging and pump drainage pipe, be incorporated with a kind of polyurethane chemistry inflation fluid 4, being incorporated with in the cavity between interior bagging and pump drainage pipe can be water or air or another kind of liquid polyurethane with the react reaction medium 5. this reaction mediums of rapid expanding of polyurethane chemistry inflation fluid.As long as firmly interior bagging is crushed earlier, be inserted in the gas extraction hole during use, reaction medium will mix with chemically expansible liquid again; Expand reaction rapidly; Make the expansion sleeve diameter become big, block pump drainage pipe and gas extraction hole automatically in a few minutes, methane gas is discharged along pipeline; Prevent gas to external leakage, guarantee downhole safety.
