Description
Technical field
This utility model relates to a kind of spy high pressure water drilling blowout prevention part flow arrangement, belongs to drilling technique field.
Background technology
When the underground coal mine hydraulic pressure water under high pressure area construction leting speeper more than 1.5MPa is holed, after water under high pressure is shown in boring, spray from aperture advantage, and carry out a large amount of stone, even eject drilling rod, stone is also easy to wound the exposed positions such as the hands of people, face after being sprayed at a high speed, finally results in and cannot draw brill, cannot close watt road and flood roadway, and potential safety hazard is bigger.Therefore, regulation in country's " mine geological hazards regulation ", such creeps into and moves back brill and should use back-pressure and have the method for blowout hookup to carry out creeping into and controlling drilling rod.If certain ore deposit is when underground construction is visited and put ash water under high pressure boring difficult to understand, owing to not taking these measures, the most once after there is unexpected water outlet drilling rod uncontrollable, in no time ejected by water under high pressure and by top to tunnel, nearly hundred meters of drilling rod image planes bars are equally twisted into twisted shape, narrowly lead to personnel casualty accidents.
Utility model content
For solving above-mentioned technical problem, this utility model provides one to visit high pressure water drilling blowout prevention part flow arrangement, the technical scheme is that
A kind of spy high pressure water drilling blowout prevention part flow arrangement, including anti-spray chamber, sealing chamber, diffluence pass, anti-spray chamber is hollow circular cylinder structure, and sealing chamber is hollow frustum structure, anti-spray chamber one end adpting flange, the other end threadeds with sealing chamber, and anti-spray chamber side is connected with diffluence pass and through with blowout prevention intracavity chamber.
Using this utility model of technique scheme, compared with prior art, it provides the benefit that:
Simple in construction, easy to operate, safe and reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment；
Water cavity structure schematic diagram till Fig. 2；
In figure: ring flange 1；Anti-spray chamber 2；Sealing chamber 3；Diffluence pass 4；Sealing gasket 5, horseshoe mouth 6.
Detailed description of the invention
This utility model is further elaborated by the embodiment be given below in conjunction with the accompanying drawings, but embodiment does not constitutes any restriction to this utility model.
See Fig. 1, Fig. 2, a kind of spy water under high pressure boring blowout prevention part flow arrangement, anti-spray chamber 2 is the cylindrical structure of hollow, sealing chamber 3 is the frustum structure of hollow, and anti-spray chamber 2 one end is connected with flange 1, and the other end is threadeded with sealing chamber 3, bottom sealing chamber 3, anti-spray chamber 2 junction is provided with sealing gasket 5, anti-spray chamber 2 side is connected and through with diffluence pass 4, and diffluence pass 4 outer end is provided with horseshoe mouth 6, and the height of anti-spray chamber 2 is less than or equal to 200 millimeters.Anti-spray chamber 2 plays certain release effect, stops Drilling Water to spray to outside hole by sealing chamber 3, plays shunting decompression effect by diffluence pass 4, prevents water from therefrom spraying in gap between central hole and drilling rod by sealing gasket 5.The present embodiment is when practicality, mating band hydraulic gripper automatic clamping function rig uses, and is arranged on high pressure watt road, aperture by this device when creeping into predetermined level, and lower good sealing gasket 5, blowout prevention shunting action is played, it is ensured that visit the construction of water under high pressure drilling safe when water under high pressure sprays.
The foregoing is only the embodiment that this utility model is the most feasible, not thereby limit to interest field of the present utility model, the equivalent structure change that all utilization this utility model description and accompanying drawing content are made, within being both contained in interest field of the present utility model.
