And impact anvil block 12 is positioned by the shoulder b of 9 inner hole of outer tube.
Toroidal cavity 19 is formed between block stamp bar 10 and outer tube 9, and side drainage channel is formed between lower cylinder sleeve 11 and outer tube 9
22.10 middle and lower part of block stamp bar has throttle orifice 21, and impacting has drain hole 23 in the middle part of anvil block 12.
The interlocking-type hammer valve system course of work provided by the present invention that hydraulic impacter working performance can be improved:
Fig. 1 is the initialization that the interlocking-type provided by the present invention that hydraulic impacter working performance can be improved hammers valve system into shape
State, valve 7 living are suspended on the U-shaped card slot position of limit pad 5, and there are a free travel in 7 lower end surface of valve and 10 upper surface of block stamp bar living
Distance H18 (3mm~30mm).Fluid passes through drainage tube 3 through 1 inner hole of top connection by hydraulic impacter drill string bore passage
Centre bore 13 enter 7 centre bore of valve living, liquid stream passes through 7 lower side drainage hole 16 of valve outflow living, through 7 lower end surface of valve living and block stamp
Free travel gap H between 10 upper surface of bar enters lower piston chamber a by the center water hole of block stamp bar 10, due to block stamp bar
The throttling action of throttle orifice 21 on 10, lower piston chamber a pressure rise, since the toroidal cavity 19 of block stamp bar 10 and outer tube 9 is logical
Cross down 11 outside drainage channel 22 of cylinder sleeve, the drain hole 23 of impact anvil block 12 is connected to impact 12 center water hole of anvil block, annular sky
Liquid stream in chamber 19 is connected with the low-pressure area of 9 outside of outer tube, and liquid stream is greater than in the fluid pressure that 10 lower end surface of block stamp bar generates
10 outside of block stamp bar, therefore, 7 upper and lower side of valve living and the block stamp component upper and lower side production being made of block stamp upper section connector 8, block stamp bar 10
Raw pressure difference.Since 7 mass of valve living is much smaller than block stamp component, valve 7 living, prior to block stamp component uplink, works as work under pressure difference effect
When moving on to the upper end face and 3 shoulder lower plane butt of drainage tube on valve 7,7 stop motion of valve living.Then, block stamp component is in pressure difference
Under effect, move upwards, when moving to 10 upper surface of block stamp bar and 7 lower end surface of valve collision living, valve 7 living and 10 upper end of block stamp bar
Face binding face is in sealing state, is cut off by the fluid course that free travel H flows through 10 center of block stamp bar, in 7 outer diameter of valve living and punching
The annulus and 7 internal flow pressure of valve living that 8 inner hole of hammer stem top connection is formed increase (water attack effect) suddenly, due to valve 7 living
Bottom shoulder 17 at annular area area presence, formed and valve 7 living pushed down on and block stamp component is pushed up into both direction phase
Anti- active force, under the two contrary active forces, valve 7 living tightly fits together with block stamp bar 10, enhance valve,
The sealing effect of hammer tip guarantees that water hammer experiment does not dissipate.Since center water route moment is cut off, huge surge pressure makes valve living
7 and block stamp valve module living it is quickly downward, start stroke movement.
Since interlocking-type of the invention hammers valve system advantage into shape, liquid stream is in the shoulder area of valve 7 living and the ring of block stamp top connection 8
Interlocking power is formed on the upper surface of shape space, the interlocking power that mutual interlocking gear is formed makes hydraulic impacter block stamp component and valve 7 living under
Hammer and valve holding are combined closely in row stroke procedure, and DL synchronization will not generate midway and prematurely pop out phenomenon.When valve 7 living and punching
When hammer component goes downwards to the restraining position of limit pad 5 together, the U-shaped card slot mouth of limit pad 5 tangles valve 7 living, and valve 7 living is prevented to continue
Downlink.Block stamp component is detached from 7 lower end surface of valve living under inertia force effect and continues traveling downwardly, and covers free travel H, 10 bottom of block stamp bar
Anvil block 12 is struck, impact force passes to the drill bit of hydraulic impacter by anvil block 12, carries out detritus acting.At this point, due to block stamp
Departing from a distance H, the center water route of hydraulic impacter is opened, and is started next for 10 upper surface of bar and 7 lower end surface of valve living
Working cycles, in cycles, block stamp bar 10 strike anvil block 12 with certain frequency and ballistic work, and punching of surging is passed to by transfer device
It hits at the drill bit of device, carries out detritus acting.In block stamp uplink return stroke, the moment that block stamp bar 10 and valve 7 living are closed, due to
Interlock the presence of power, block stamp bar 10 and valve living 7 can rapid closing, generate huge water hammer experiment, avoid hammering into shape in the prior art, valve touches
Rebound is generated when hitting closure causes hammer, valve closure not tight, reduces water hammer experiment, influences hydraulic impacter output performance.It is mutual to hammer valve into shape
Latch mechanism improves the sealing performance of hydraulic impacter block stamp bar 10 and valve 7 living, improves waterpower utilization rate, improves punching of surging
Hit the working performance of device.
The present invention is explained in detail above in conjunction with drawings and examples, but the present invention is not limited to above-mentioned implementations
Example, within the knowledge of a person skilled in the art, can also make without departing from the purpose of the present invention
Various change out.The content being not described in detail in the present invention can use the prior art.
