Specific embodiments
Below in conjunction with accompanying drawing, three routine embodiments of the present invention are elaborated:
Embodiment one is as shown in Figure 1: the hammer body (3) that down-hole hammer is made up of shell (1), mainspring (2), upper hammer and lower hammer, core valve (4), valve spring (5), lower contact (6) are formed; By being threaded between shell (1) with lower contact (6) and between upper hammer with lower hammer, mainspring (2) is enclosed within epimere and the stage casing of upper hammer, and core valve (4) and valve spring (5) are contained in lower hammer inner chamber.Valve spring (5) is enclosed within core valve (4) outward, is positioned between the ring-type major part (9) at core valve top and inner chamber step (11); Upper hammer epimere coordinates (7) with movable sealing between shell, and between lower hammer hypomere and the cylindrical inner of lower contact epimere, movable sealing coordinates (7); Working solution enters from shell (1) upper end, flow through the inlet opening (8), the sump pit (12) of core valve (4) bottom, the hammer body cavity of resorption (13) and after axially running through the outage (14) of lower contact (6) that axially run through hammer body (3), discharged by lower contact (6) lower end; Annular space (10) between hammer body (3) and shell (1) is by by-pass prot (15) and lower contact (6) inner space.The hammering face of described lower hammer and dress core valve (4) within it, valve spring (5) and lower contact (6) forms core valve type valve control mechanism;
Operation principle: working solution enters the inlet opening (8) of upper hammer through shell upper end, sump pit (12) again through core valve (4) bottom arrives at lower hammer cavity of resorption (13), now the outage (14) in lower contact (6) is closed by core valve (4), hydraulic pressure is by hammer body (3) upwards lifting compress mainspring (2) and valve spring (5), when the compression stress of valve spring (5) is greater than the downforce of core valve (4), valve just can be opened suddenly, working solution releases from outage (14), hammer body cavity of resorption (13) hydraulic pressure rapid drawdown, hammer body (3) impacts lower contact (6) under mainspring (2) thrust, core valve (4) also cuts out outage (14) thereupon, hammer body (3) enters next impulse period, go round and begin again and ceaselessly impact.
Embodiment two is as shown in Figure 2: down-hole hammer is made up of shell (1), end cap (16), upper spring seat (17), hammer body (3), mainspring (2), lower spring cup (18), core valve (4), valve spring (5), lower contact (6); By being threaded between shell (1) with lower contact (6) and between end cap (16) with hammer body (3), mainspring (2) is contained among hammer body epicoele (19), core valve (4) is applied in hammer body lumen (21) and hammer body cavity of resorption (13), valve spring (5) is enclosed within core valve (4) stage casing, is positioned between the ring-type major part (9) at core valve top and hammer body lumen (21) step; The mozzle on shell (1) top is with between end cap (16) and be movable sealing between hammer body (3) hypomere with lower contact (6) epimere cylindrical inner and coordinate (7); Working solution enters from shell (1) upper end, is passed to hammer body cavity of resorption (13) through hammer body epicoele (19), liquid-through hole (20) between core valve (4) and hammer body (3), is finally discharged by the outage (14) in lower contact (6) hypomere.
The hammering face of described lower hammer and dress core valve (4) within it, valve spring (5) and lower contact (6) forms core valve type valve control mechanism.
Operation principle: working solution enters hammer body (3) inner chamber by shell upper end, hammer body cavity of resorption (13) is arrived at through liquid-through hole (20), now the outage (14) in lower contact is closed by valve (22), hydraulic pressure is by hammer body (3) upwards lifting compress mainspring (2) and valve spring (5), when the compression stress of valve spring (5) is greater than the downforce of core valve (4), valve (22) just can be opened suddenly, working solution releases from outage (14), hammer body cavity of resorption (13) hydraulic pressure rapid drawdown, hammer body (3) impacts lower contact under mainspring (2) thrust, core valve (4) also cuts out outage (14) thereupon, hammer body (3) enters next impulse period, go round and begin again and ceaselessly impact.
Embodiment three as shown in Figure 3; The hammer body (3) that down-hole hammer is made up of shell (1), mainspring (2) upper hammer and lower hammer, core valve (4), valve spring (5), lower contact (6) are formed; Between shell (1) and lower contact (6) and be between upper hammer and lower hammer and be rigidly connected, mainspring (2), core valve (4) are all identical with embodiment 1 with installation site with the structure of valve spring (5); Upper hammer epimere coordinates (7) with movable sealing between shell, and lower hammer hypomere and housing lower section also adopt movable sealing to coordinate (7); Working solution is entered by shell (1) upper end, from lower contact (6) outage (14) discharge, between working solution circulation identical with embodiment 1.The difference forming structure is: described lower contact (6) does not have cylindric epimere, and the top of lower contact is hammering face, and there are outage (14) in central authorities, and core valve (4) lower surface and outage (14) upper surface form valve and valve seat; Described shell (1) tube wall has by-pass prot (15), and when hammer body (3) reciprocating impact moves, the annular space (10) between hammer body (3) and shell (1), is sucked by by-pass prot (15) or discharges working solution.
Operation principle is identical with embodiment 2 with embodiment 1.
