Abstract
The invention relates to a double-channel and double-sided emptying fluidic element for a jet-type hydro-hammer, wherein two circular cross section signal channels or two flat cross section signal channels and two bottom plate emptying channels are arranged on a bottom plate of the fluidic element; two circular cross section signal channels or two flat cross section signal channels and two cover plate emptying channels are arranged on a cover plate of the fluidic element; a substrate is arranged between the bottom plate and the cover plate of the fluidic element; and the substrate is provided with two symmetric control channels and two symmetric emptying channels. The structural form of the fluidic element is improved; the thickness of the bottom plate and the cover plate of the flat cross section signal channels is reduced; the thickness of the substrate is increased; the discharge current capability of a nozzle is increased; double-sided run-through emptying is realized by replacement of two signal channels of the prior fluidic element with four signal channels; the passage areas of the emptying channels are increased compared with the prior single-sided nonpenerative emptying; the discharge current capability of the fluidic element is effectively strengthened; the flow rate of fluid flow of the emptying channels and working chambers is reduced; erosion of slurry on the fluidic element and a cylinder body of the hammer is lightened; and the operating life of the fluidic element is obviously prolonged.
Description
Technical field:
The present invention relates to a kind of fluidic of drilling tools, especially the jetting type used of the oil/gas drilling percussion drilling impactor fluidic that surges.
Background technology
The core component of hydraulic impacter is exactly a fluidic, and in a sense, the life-span of fluidic has determined the length of impactor service time.With regard to the mode of occupation of present various fluidics, its life-span is not long.Therefore, the insider repeatedly improves fluidic, improve one's methods nothing more than two kinds: the 1. wear-resisting Hardmetal materials of edge one deck on the cover plate of fluidic and base plate, perhaps simultaneously substrate is also all used the carbide alloy manufacturing, to increase its application life by the mode that changes the fluidic material.2. the shunting gland is set above the fluidic nozzle, a part that enters the fluidic fluid is divided to beyond the fluidic, reduce entering the fluid flow of fluidic, thereby reach the purpose that reduces fluid scouring and increase the service life.But this method has significantly reduced the energy of fluidic jet, simultaneously, and shunting gland structure complexity, and unreliable.More than two kinds of methods to a certain extent to improving the application life of fluidic, but this in actual applications raising does not also reach requirement far away, reason has only the signal road (being that element one has two signal roads) of a circular cross-section corresponding with it with regard to being the present jetting type every side of the impactor fluidic control road that surges, under the situation that signal road flow section amasss necessarily and the fluidic general thickness is certain, substrate thickness is difficult to increase, and base plate and cover sheet thickness are bigger, thereby the through-current capability that makes fluidic nozzle place is difficult to increase, if do not take the shunting measure, then flow velocity is higher everywhere for nozzle place and fluidic working chamber, be subjected to slurry erosion serious, the fluidic working life is short, influences the jetting type efficient detritus of impactor that surges and creeps into the performance of advantage.
Summary of the invention:
Purpose of the present invention just is to provide a kind of dual-channel double-face emptying flow injection element at above-mentioned the deficiencies in the prior art.
The objective of the invention is to be achieved through the following technical solutions:
Fluidic base plate 3 is provided with two circular cross-sections or signal road, pancake cross section 2 and two base plate emptying roads 8,5 are provided with two circular cross-sections or signal road, pancake cross section 2 and two cover plate emptying roads 7 on the fluidic cover plate, be substrate 4 between fluidic base plate 3 and the fluidic cover plate 5, substrate 4 is provided with two the control roads 1 and the emptying road 6 of symmetry, emptying road 6 and cover plate emptying road 7, base plate emptying road 8 is connected, the control road 1 of fluidic base plate 3 is communicated with the signal road 2 that fluidic base plate 3 is provided with, the control road 1 of fluidic cover plate 5 is communicated with fluidic substrate 4 with the signal road 2 that fluidic cover plate 5 is provided with, base plate 3, cover plate 5 threes closely connect and compose by bolt.
Beneficial effect: dual-channel double-face emptying flow injection element, it has improved the form of structure of present jet flow type shocker fluidic, signal road, pancake cross section further reduces the thickness of base plate and cover plate, increase the thickness of substrate, thereby increase the through-current capability at nozzle place, two signal roads that replace old-fashioned fluidic with four signal roads, realize the two-sided emptying that both sides connect, the one-sided emptying of more existing non-perforation, two-sided emptying has increased the emptying area of passage, effectively strengthen the through-current capability of fluidic, emptying road and working chamber liquid flowing speed have been reduced, alleviate the erosion of impact device inboard wall of cylinder block, alleviate the erosion of mud, the working life of significant prolongation fluidic fluidic and impactor cylinder body.

The specific embodiment:
Be described in further detail below in conjunction with drawings and Examples:
Fluidic base plate 3 is provided with two circular cross-sections or signal road, pancake cross section 2 and two base plate emptying roads 8,5 are provided with two circular cross-sections or signal road, pancake cross section 2 and two cover plate emptying roads 7 on the fluidic cover plate, be substrate 4 between fluidic base plate 3 and the fluidic cover plate 5, substrate 4 is provided with two the control roads 1 and the emptying road 6 of symmetry, emptying road 6 and cover plate emptying road 7, base plate emptying road 8 is connected, the control road 1 of fluidic base plate 3 is communicated with the signal road 2 that fluidic base plate 3 is provided with, the control road 1 of fluidic cover plate 5 is communicated with fluidic substrate 4 with the signal road 2 that fluidic cover plate 5 is provided with, base plate 3, cover plate 5 threes closely connect and compose by bolt.
