Description
Technical field
Powder exhaust device is forced the present invention relates to a kind of water control segmentation pressure, is particularly suited for coal mine down-hole drilling row's powder and is used.
Background technology
It is one of main method of control of coalmine gas to carry out gas pumping using drilling, but the phenomenons such as " collapse hole ", " plug-hole " often occur during drilling, and then produces bit freezing, stick of tool, and the current country there is no efficient processing method.
The content of the invention
The present invention be directed to problems of the prior art, there is provided a kind of simple structure, can carry out be segmented pressure force row powder device.
It includes that tapered head height pressure seal drill rod 1, water control pressure force row's powder device 1, tapered head height pressure seal drill rod 2, water control pressure to force row's powder device 2, drill bit；Tapered head height pressure seal drill rod 1, water control pressure force row's powder device 1, tapered head height pressure seal drill rod 2, water control pressure to force row's powder device 2 and drill bit to be interconnected successively by tapered thread, and junction is in sealing state by the O-ring at connection screw thread.
Water control pressure forces row's powder device 1, and it includes jet body, seal head, compression spring, sealed base, O-ring 1, O-ring 2, guiding screw pole；Front end is arranged with two apopores on jet body, diameter is generally 1mm ~ 3.5mm, it is connected through a screw thread on circumferencial direction and is evenly equipped with three guiding screw poles, three track runners are evenly equipped with seal head circumference, guiding screw pole bottom is installed to inside the track runner of seal head, sealed base is installed on inside jet body, and by O-ring 1）Carry out individual event sealing, sealed base front end is provided with compression spring, and precompressed is carried out by seal head, O-ring 2 installs, seal head front end interior with the O-ring groove of jet body front end and is provided with tapered head, and rear end sets fluted, recessed circumferential has carried out chamfering, the chamfering on rearmost flute periphery coordinates with the tapered head of tapered head height pressure seal drill rod front end, sealing function is produced, when being reached to a certain degree by hydraulic impact, the tapered head of seal head front end coordinates with sealed base, produces sealing function.
The depth that the present apparatus is drilled according to colliery, installs a water control pressure for every 5 ~ 10 meters between tapered head height pressure seal drill rod 1 and tapered head height pressure seal drill rod 2 and forces row's powder device 1.
It is sequentially reduced with being provided with the water-carrying capacity needed for the water control pressure installed for before, from back to front in the direction of drill bit forces row's powder device to close seal head.
Beneficial effect：The present invention is provided with water control pressure and forces row's powder device, and in normal drilling, row's powder hydraulic pressure is relatively low, and water control pressure everywhere forces the apopore water yield in row's powder device smaller, and substantial amounts of water flows out row's powder by drill bit Cooling Holes.After finding that plug-hole occurs in drilling, regulation output makes rearmost end water control pressure force the seal head of row's powder device and sealed base to produce sealing to coordinate, rise rapidly in hydraulic pressure, it is discharged in drilling by apopore, if after generating plug-hole phenomenon herein, hydraulic pressure in drilling also persistently rises, force to discharge the boring mud of plug-hole by pressurizeing, until drilling water outlet, it is then shut off water under high pressure, from new unlatching, water-carrying capacity setting is forced row's powder device flow to that can close second level water control pressure, the second level starts the row's of pressure powder, by that analogy, it is final to be able to a plug-hole phenomenon discharge, effectively prevent because cannot arrange powder and caused by bit freezing, stick of tool phenomenon.
