Abstract
The utility model provides an energy -conserving impacter of air input adaptive, includes the distribution seat, be equipped with the central gas pocket intercommunication of air flue with distribution seat outside air chamber and piston on the distribution seat, be equipped with the exhaust choke valve in the air flue, the exhaust choke valve is equipped with an initial pressure value, the exhaust choke valve was opened when the atmospheric pressure and the initial pressure sum of piston center gas pocket were greater than distribution seat outside air chamber atmospheric pressure. This device simple structure, can be along with the automatic air input that increase of the increase of bore depth to reduce total air consumption, reduce the energy consumption, reach energy saving and emission reduction's effect.
Description
Technical field
This utility model is related to a kind of air inflow adaptive energy-saving impact device.
Background technology
It is that outdoor drillhole blasting, well, underground heat and deep-well drilling industry are general at present that down-the-hole drilling system carries out bore operation
All over the high-efficiency high-quality pore-forming operation technique using, but the conventional drilling tool that adopted of down-the-hole drilling system hole depth in deep hole construction
Reach during certain depth because bottom hole negative pressure is big, produce two big defects: 1, deslagging is not smooth, leads to drilling depth relatively slow, or even no
Method is crept into；2nd, the easy recharge of hole bottom slurry causes impacter internal motion parts stuck, leads to drilling system to abend work.
Modern well, hot hole construction sometimes require boring the super 300m of drilling depth, with reach its engineering method require.For making down-the-hole drilling tool
System has penetration rate after boring reaches certain depth and does not decline and reduce generation hole depth and reaches mud when certain depth and return
The construction ability of the probability filling, the measure implemented at present is to design the big down-the-hole drilling system of blast consumption, that is, increases whole
The air inlet of structure, though this scheme can reach engineering method reluctantly and require, when its deficiency is shallow bore hole, does not need so big air inlet
Amount, hence in so that a whole set of drilling system blast consumption is big, oil consumption is big, causes energy dissipation, and it is laggard to reach certain depth in hole depth
Chi speed declines substantially.
Utility model content
This utility model is directed to the deficiencies in the prior art and provides that a kind of structure is simple, automatically can increase with the increase of hole depth
Big air inflow, thus reducing total air consumption, reducing energy consumption, reaches the adaptive energy-saving impact of air inflow of the effect of energy-saving and emission-reduction
Device.
This utility model adopts the following technical scheme that realization: a kind of adaptive energy-saving impact device of air inflow, including distribution
Seat, described distribution seat is provided with air flue and is connected air chamber outside distribution seat with the centre porosity of piston, the row of being provided with described air flue
Gas choke valve, described exhaust shutter is provided with an initial pressure value, the air pressure of described piston centre pore and initial pressure it
With more than outside distribution seat during air chamber air pressure exhaust shutter open.
Described exhaust shutter includes split pin, throttling steel ball and throttling spring, and what described air flue included being interconnected leans on
The inlet channel of air chamber and the outlet passageway near centre porosity outside nearly distribution seat, described throttling steel ball is arranged on entering of air flue
In gas passage, one end of described throttling spring is fixed in outlet passageway, and the other end is connected with throttling steel ball, described throttling steel ball
The internal diameter with diameter greater than outlet passageway, less than inlet channel internal diameter, described throttling steel ball is by being arranged in inlet channel
Split pin axial limiting in inlet channel, the air inlet of described outlet passageway be provided with and the steel ball mating shapes that throttle arc
Degree so that throttling steel ball seal when the air inlet with outlet passageway under air chamber gas pressure outside distribution seat contacts described in give vent to anger
The air inlet of passage, throttling one initial pressure moving from outlet passageway of steel ball given to inlet channel by described throttling spring.
Due to adopting said structure, when carrying out borehole drilling drilling, hole depth reaches certain depth, inside and outside distribution seat
The difference of air pressure makes exhaust shutter automatically turn on, thus increasing the air inflow of drilling system it is ensured that deslagging smoothly, reduces hole
As deep as to mud recharge risk when certain depth, using this impacter drilling system in shallow bore hole, due to the center of piston
The pressure of pore is less than admission pressure, and exhaust shutter is closed, thus reducing air consumption, reducing energy consumption, and reach energy-saving and emission-reduction
Effect.
Brief description
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of this utility model distribution seat.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, this utility model is described further.
As shown in Figure 1, 2, a kind of adaptive energy-saving impact device of air inflow, including distribution seat 1, described distribution seat 1 sets
There is air flue 11 to connect air chamber outside distribution seat 2 with the centre porosity 4 of piston 3, be provided with exhaust shutter in described air flue 11, institute
State exhaust shutter and include split pin 12, throttling steel ball 13 and throttling spring 14, described air flue includes gas outside distribution seat
The inlet channel of room and the outlet passageway near centre porosity, described throttling steel ball 13 is arranged in the inlet channel of air flue, institute
State throttling spring 14 to be arranged in outlet passageway, described throttling steel ball 13 is arranged on throttling spring 14 and is arranged in inlet channel
Split pin 12 between, split pin 12 will throttle steel ball 13 axial limiting in inlet channel, described throttling steel ball 13 diameter
Internal diameter more than outlet passageway, the internal diameter less than inlet channel, the air inlet of described outlet passageway is provided with and throttles steel ball shape
The radian matching is so that throttling steel ball is close when contacting with the air inlet of outlet passageway under air chamber gas pressure outside distribution seat
Seal the air inlet of described outlet passageway, described throttling spring give throttling steel ball one from outlet passageway move to inlet channel at the beginning of
Beginning pressure.When the air pressure of described piston centre pore is more than air chamber air pressure outside distribution seat with the initial pressure sum of throttling spring
When exhaust shutter open so that air chamber is connected with piston centre pore outside distribution seat, thus increase air inflow it is ensured that
Deslagging is smooth.
This impacter is applied in deep-well drill tool system, deep-well drill tool system include spiral-flow type drill bit, drill bit, impacter,
Pin and box sub, drilling rod, centralizer, above-mentioned part is sequentially coaxially arranged, thus formed a kind of synchronously increasing with hole depth air consumption
Deep-well drill tool system.
The above, only this utility model is embodied as case explanation it is impossible to limit right of the present utility model with this
Protection domain.All equivalence changes made according to this utility model application claims and description and modification, all exist
In the range of this utility model protection.
