The specific embodiment
Hydraulic in-the-hole hammer with dual nozzles and combined valve comprises shell 1, upward valve 2, block stamp 3, block stamp hold spout 4 and lower contact 5, shell 1 central upper portion is provided with top nozzle 6, this nozzle is over against the last valve epicoele 7 and the centre bore 9 of last valve 2, and the jet that can utilize liquid stream high-speed motion to form produces the low pressure effect in last valve epicoele 7 positions; The internal diameter at last valve 2 external diameters and shell 1 this position forms and is slidingly matched, and this fitting face has groove 8 longitudinally, and last valve 2 can move up and down freely and have spacingly when moving downward, and movement travel is A, and the value of A is the 1-500 millimeter.Block stamp 3 epimeres and shell 1 forms and is slidingly matched, the endoporus of hypomere and the epimere of lower contact 5 form be slidingly matched guarantee block stamp 3 up and down flexible motion and form at slide plane seal, the block stamp stroke that moves up and down is A+B, B is a free travel, and the value of B is the 1-500 millimeter; Be communicated with by last valve by-pass prot 10 between the centre bore 9 of last valve and the block stamp epicoele 11; The lower surface of last valve 2 can form flat seal with the upper surface of block stamp 3, when block stamp 3 is up to can contact with last valve 2 time centre bore 12 and the block stamp epicoele 11 of block stamp is closed.Fixedly be equipped with block stamp in the block stamp 3 and hold spout 4, hold spray chamber 15 with the distance formation that block stamp nozzle 13 assurances in the block stamp 3 are certain, when block stamp nozzle 13 has high-velocity liquid jet to form, block stamp holds spout 4 kinetic energy of this jet is changed into the pressure energy, and the hydraulic action that utilizes block stamp cavity of resorption 18 areas to overcome top upwards lifts block stamp 3; On the block stamp inwall that holds around the spray chamber 15, have the bypass mouth of a river 14, be communicated with block stamp low pressure ring cavity 17 outward, be communicated with the drainage channel of hydraulic in-the-hole hammer bottom by lower contact by-pass prot 19 and lower contact centre bore 20 then holding spray chamber 15.
The diameter phi 1 of nozzle 6 is the 3-500 millimeter.
The diameter phi 2 of the nozzle 13 of block stamp 3 inside is the 1-500 millimeter;
The diameter phi 3 that block stamp holds spout centre bore 16 is the 3-500 millimeter;
The course of work of this hydraulic in-the-hole hammer is as follows: hydraulic in-the-hole hammer under erectility on valve 2, block stamp 3 be in oneself lower position respectively, free travel B is arranged between the lower surface of last valve 2 and the block stamp; As the high-pressure fluid hydraulic in-the-hole hammer of flowing through, this fluid at last valve epicoele 7 places formation underbalance effect, will be gone up valve 2 and raise during through the nozzle 6 on shell 1 top; After this fluid is flowed through last valve centre bore 9, upward valve by-pass prot 10, block stamp epicoele 11, block stamp endoporus 12 and block stamp nozzle 13 successively, form high-speed jet and rush at the centre bore 16 that block stamp holds spout 4, the kinetic energy that holds at block stamp under the effect of spout 4 liquid is converted into the pressure energy, make block stamp cavity of resorption 18 pressure rise, block stamp 3 is lifted and accelerated motion upward.The climb acceleration of last valve 2 will be higher than the climb acceleration of block stamp 3, the distance of the upper limit position of block stamp arrival simultaneously is that A+B is longer than the movement travel of last valve, valve 2 move stroke A and first arrival upper limit position goes to wait for that block stamp 3 arrives soon after thereby guarantee to go up, when block stamp 3 moves upward to when contacting with last valve 2, last valve 2 lower surfaces are with the inlet sealing of block stamp endoporus 10, blocked the passage of liquid stream, block stamp nozzle 13 aneroids stream process, block stamp cavity of resorption 18 holds spout centre bore 16 with low pressure ring cavity 17 by block stamp, the bypass mouth of a river 14 that block stamp holds on spray chamber 15 and the block stamp is communicated with, the high pressure that jet forms disappears, and the liquid in the block stamp cavity of resorption 18 can be spout 4 by block stamp, the bypass mouth of a river 14 on the block stamp, block stamp and shell 1 annular gap are discharged to lower contact by-pass prot 19 and lower contact centre bore 20.Block stamp 3 and last valve 2 be common accelerated motion downwards under the pressure differential effect of liquid, valve 2 on when movement travel reaches A is owing to arrive the lower limit stop motion, 3 of block stamps overcome under the effect of its own inertial power because the fluidic channel of nozzle 13 is opened the back continues to move downward at the pressure that block stamp cavity of resorption 18 forms, and finish free travel B and impact lower contact 5.The interior part situation of hydraulic in-the-hole hammer this moment returns to initial state again, and its inner body enters next working cycles.
