Abstract
Depressurize blowout hookup in a kind of aperture, including long 200mm, the tube body that nominal diameter is 40mm, tube cavity rear portion is equipped with three pieces of Semicircular baffles vertical with tube body axis, three pieces of Semicircular baffles are equidistantly interspersed along tube body axis, axial distance between adjacent Semicircular baffle is 30mm, the thickness of each Semicircular baffle is 3mm, and tube body front end is connected by 50X40mm bindings with drilling and sealing pipe, and rear end sets outer silk section to be connected with extraction hose.The cross-sectional area that open channel is formed between Semicircular baffle and inboard wall of tube body is the 2/5 of tube cavity cross-sectional area.During gas pumping, baffle in the utility model can make the mixture waveforms such as coal (rock) powder flowed out by drilling and sealing pipe pass through tube body, so as to which buffering and depressurization are played in the impact to mixture, and then extraction hose is prevented to come off because being subject to intense impact, avoid the occurrence of and hurt sb.'s feelings or gas accident, ensure that the normal extraction of gas.
Description
Technical field
The utility model is related to gas pumping field, be especially it is a kind of be installed on drilling and sealing pipe and extraction hose it
Between, blowout hookup is depressurized in the aperture for reducing the mixture impact forces such as coal (rock) powder sprayed.
Background technology
When carrying out extraction to fire damp, drilling construction is carried out first, and then gas is carried out using extraction hose union
Extraction.During extraction, the mixture such as remaining coal (rock) powder understands device to hole and causes to block up because of the drive of extraction negative pressure in drilling
Plug, causes that normal extraction can not be carried out, so as to cause gas pressure in hole gradually to increase；, will after pressure reaches a certain level
The generation drilling mixture such as spray orifice accident, the gas of ejection can cause gas coal that is abnormal, and spraying in drilling place and tunnel
The mixtures such as (rock) powder can then impact the extraction hose of connection, cause the disconnection of extraction hose to throw away and hurt sb.'s feelings.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of aperture decompression blowout hookup, can reduce ejection coal
The surge of the mixtures such as (rock) powder, prevents extraction hose from coming off, and avoids the occurrence of and hurts sb.'s feelings or gas accident, ensures gas just
Normal extraction.
The technical solution of the utility model is to provide a kind of aperture decompression blowout hookup having with lower structure, bag
Include long 180~220mm, the tube body that nominal diameter is 35~45mm, tube cavity rear portion is equipped with some Semicircular baffles, Ruo Gansuo
Semicircular baffle is stated equidistantly to be interspersed along the axis of tube body, the front end of the tube body is connected with drilling and sealing pipe, rear end with
Extraction hose connects.
Blowout hookup is depressurized in aperture described in the utility model, wherein, the quantity of the Semicircular baffle is three pieces, and
With tube body axis perpendicular, the axial distance between adjacent two pieces of Semicircular baffles is 30mm, and the thickness of each Semicircular baffle is equal
For 3mm.
Blowout hookup is depressurized in aperture described in the utility model, wherein, institute between the Semicircular baffle and inboard wall of tube body
The cross-sectional area for forming open channel is the 2/5 of tube cavity cross-sectional area.
Blowout hookup is depressurized in aperture described in the utility model, wherein, the tube body front end is by 50X40mm bindings with boring
Hole hole sealing tube connection, rear end sets outer silk section, is connected with extraction hose.
After above structure, compared with prior art, the utility model aperture decompression blowout hookup has the following advantages：
Due to the tube body that the utility model includes long 180~220mm, nominal diameter is 35~45mm, and if tube cavity rear portion be equipped with
The dry Semicircular baffle being equidistantly interspersed along tube body axis, during mash gas extraction, baffle can make to be sealed by drilling for this
The mixture waveforms such as coal (rock) powder of hole pipe outflow, gas are by tube body, so that the impact to mixture is played buffering and subtracted
The effect of pressure, and then prevent the extraction hose at rear portion to come off because being subject to strong impact, avoids and occurs hurting sb.'s feelings or gas
Accident, ensure that the normal extraction of gas.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model aperture decompression blowout hookup.
Embodiment
The utility model aperture decompression blowout hookup is made further specifically with reference to the accompanying drawings and detailed description
It is bright：
As shown in Figure 1, in this embodiment, the utility model aperture decompression blowout hookup includes long 200mm, public affairs
Claim the tube body 2 of a diameter of 40mm, certainly, the length of tube body 2 can also be other numerical value between 180~220mm, and nominal is straight
Footpath can also be other numerical value between 35~45mm.The inner cavity rear portion of tube body 2 is equipped with some Semicircular baffles 3, some described
Semicircular baffle 3 is equidistantly interspersed along the axis of tube body 2.The front end (Fig. 1 left ends) of tube body 2 by 50X40mm bindings with
Drilling and sealing pipe 1 connects, and the rear end (Fig. 1 right ends) of tube body 2 sets outer silk section, is connected with extraction hose 4, so as to fulfill tube body 2
With drilling and sealing pipe 1 and the fast assembling-disassembling of extraction hose 4.The Semicircular baffle 3 of interlaced arrangement can solve what is sprayed from drilling
The mixtures such as coal (rock) powder cause the gas in drilling place and tunnel abnormal, while impact extraction hose 4, cause extraction hose
4, which disconnect, throws away the problem of hurting sb.'s feelings.
In order to which in the case where ensureing preferable effect of easing stress, effectively save cost, the quantity of Semicircular baffle 3 uses three
Block, this axis perpendicular of three pieces of Semicircular baffles 3 with tube body 2, the axial distance between adjacent two pieces of Semicircular baffles 3 are
30mm, the thickness of each Semicircular baffle 3 is 3mm.
The cross-sectional area that open channel is formed between 2 inner wall of Semicircular baffle 3 and tube body is 2 lumenal cross-section of tube body
The 2/5 of area, the structure can further improve the effect of easing stress to mixtures such as coal (rock) powder, gas.
Due to the tube body 2 that the utility model includes long 200mm, nominal diameter is 40mm, and 2 inner cavity rear portion of tube body is equipped with three
The Semicircular baffle 3 that block is equidistantly interspersed along 2 axis of tube body, during mash gas extraction, Semicircular baffle 3 can make for this
