Technical field
The present invention relates to a kind of sealing of hole extraction pressure tester, a kind of underground coal mine that is particularly suitable for use in is repeatable using to coal seam
Drill the sealing of hole extraction pressure tester used.
Background technology
As China takes out to the specification of mine gas extraction, and the attention of global low-carbon environmental protection, China's coal-mine gas
Work is adopted just to be particularly important.Coordinate sealing material, method used in coal mine gas drainage etc. varied at present, still
Sum up and be divided into slurry type, the major class of expanded material type two.Slurry type material needs to use supporting electronic or pneumatic or manpower
Pumping plant, the material injection hole that will be stirred, drilling is sealed using the solidification of slurries, this method sealing of hole man-hour is longer, work
Sequence is more complicated, simultaneously because the solidification of slurries, extraction pipeline can not reclaim, and cost is higher.Expanded material is more based on polyurethane,
It utilizes the chemical reaction of chemical material, and dilatancy carries out sealing drilling, but this kind of series material reaction speed is general all
In the scope of several seconds to tens seconds, worker had little time to operate at all, reduced the performance that material should play in itself, while the material
Material is mostly that noxious material, the health of human body for the worker having a strong impact on, and the material be not also recyclable in the presence of wasting in use,
Sealing of hole cost is higher, and larger economic pressures are brought to enterprise's production.
The content of the invention
The purpose of this practicality invention is to overcome the weak point in prior art, there is provided it is a kind of simple in construction, it is easy to use,
Environment friendly and pollution-free reusable one-way expansion sealing of hole extraction pressure tester.
To achieve the above object, one-way expansion sealing of hole extraction pressure tester of the present invention includes drainage tube, drainage tube one end dress
There are KJ type mining hose straight couplings, there is floral tube one end, and there is Dilated rubber hose terminal pad centre, there is water filling joint in terminal pad, note
Water swivel connects Dilated rubber hose, and end face O-ring seal is placed in centre.Dilated rubber hose other end sets end face O-ring seal,
Slide head is connected, slide head internal groove is connected rear enclosure with Dilated rubber hose in drainage tube provided with radial direction O-ring seal.
Described one-way expansion sealing of hole extraction pressure tester, it is characterised in that：KJ types mining hose connects on the drainage tube
Head can be connected directly with extraction component, valve, pressure gauge, branch pipe.Terminal pad water filling joint directly can connect with water injection pipe and valve
Connect.
Described one-way expansion sealing of hole extraction pressure tester, it is characterised in that：The extraction length of tube is according to live sealing of hole
Length determines.
Described one-way expansion sealing of hole extraction pressure tester, it is characterised in that：The Dilated rubber hose is in certain water injection pressure
It is lower that there is inflatable retractility.
Described one-way expansion sealing of hole extraction pressure tester, it is characterised in that：The slide head front end is provided with big chamfering, interior
Portion is provided with groove, places radial direction O-ring seal.
Described one-way expansion sealing of hole extraction pressure tester, it is characterised in that：The floral tube is provided with multiple air admission holes, interior
Portion sets screen pack.
Beneficial effect：The one-way expansion sealing of hole extraction pressure tester is invented, orientation fixed point sealing of hole can be achieved, Dilated rubber hose is swollen
Swollen coefficient is big, is not bounced back after expansion, and seal bore diameter scope is wide, and water injection pressure is small, and the product of sealing of hole extraction pressure measurement one use, and use can return
Receive expanded rubber water filling and carry out sealing of hole, only need a water injecting pump or manual pump to complete sealing of hole, solve existing hole-sealing technology
The problem of complicated, and filled without using chemical synthesis slurries, nontoxic pollution-free is simple in construction, easy to use, can reclaim repeatedly
Utilize, there is distinct economic and practicality.
