Description
Technical field
The present invention relates to a kind of water control segmentation pressure to force powder exhaust device, and being particularly suitable for coal mine down-hole drilling row's powder makes
With.
Background technique
One of the main method that gas drainage is control of coalmine gas is carried out using drilling, but during drilling often
There is phenomena such as " collapse hole ", " plug-hole ", and then generate bit freezing, stick of tool, the current country there is no efficient processing method.
Summary of the invention
The present invention aiming at the problems existing in the prior art, provides that a kind of structure is simple, it is strong to be able to carry out segmentation pressure
The device of system row's powder.
It includes tapered head height pressure seal drill rod 1, water control pressure pressure row powder device 1, tapered head height pressure seal drill rod 2, water
Governor pressure forces row powder device 2, drill bit；Tapered head height pressure seal drill rod 1, water control pressure force row powder device 1, tapered head height means of press seals
Drilling rod 2, water control pressure force row's powder device 2 and drill bit to pass through tapered thread and successively interconnect, and pass through connection spiral shell
O-ring at line makes junction be in sealing state.
Water control pressure force row's powder device 1 it include jet body, it is seal head, compression spring, sealed base, O-ring 1, O-shaped
Enclose 2, guiding screw pole；Front end is symmetrically arranged with two apopores on jet body, and diameter is generally 1mm ~ 3.5mm, leads on circumferencial direction
It is uniformly distributed there are three guiding screw pole to cross threaded connection, uniformly distributed on seal head circumference there are three track runner, the installations of guiding screw pole bottom end
To inside the track runner of seal head, sealed base is installed on inside jet body, and passes through O-ring 1) individual event sealing is carried out, it is close
Envelope pan frontward end is equipped with compression spring, and carries out precompressed, the O-ring of O-ring 2 installation and jet body front end by seal head
Slot is interior, seal head front end is provided with tapered head, and rear end setting is fluted, and recessed circumferential has carried out chamfering, rearmost flute periphery
The tapered head of chamfering and tapered head height pressure seal drill rod front end cooperates, and generates sealing function, is reached a certain level by hydraulic impact
When, the tapered head and sealed base of seal head front end cooperate, and generate sealing function.
The depth that the present apparatus is drilled according to coal mine, every 5 ~ 10 meters in tapered head height pressure seal drill rod 1 and tapered head height pressure
One water control pressure is installed between sealing drilling rod 2 and forces row's powder device 1.
Be equipped with the direction of drill bit be before, the water control pressure installed forces row's powder device to close seal head institute from back to front
The water flow needed is sequentially reduced.
The utility model has the advantages that the present invention, which is equipped with water control pressure, forces row's powder device, when normally drilling, row's powder hydraulic pressure is lower, everywhere
Water control pressure force row powder device in apopore water yield it is smaller, a large amount of water by drill bit cooling hole outflow row powder.Work as hair
After now plug-hole occurs in drilling, adjusting water supply makes rearmost end water control pressure force the seal head of row's powder device and sealed base generation close
Envelope cooperation, rises rapidly in hydraulic pressure, is discharged in drilling by apopore, if after producing plug-hole phenomenon herein, in drilling
Hydraulic pressure also persistently rises, and forces for the boring mud of plug-hole to be discharged by pressurization, until drilling water outlet, is then shut off high pressure water, from new
It opens, water flow setting is forced row's powder device flow to that can close second level water control pressure, the second level starts the row of pressure
Powder, and so on, it is finally able to a plug-hole phenomenon discharge, effectively prevents bit freezing caused by due to can not arrange powder, stick of tool phenomenon.
