Abstract
The utility model overcomes it is not enough that prior art exists, provide one kind send split effectual, send and split efficient can change and send release head that splits direction, in order to solve the technical problem, the utility model discloses a technical scheme do: can change and send release head that splits direction, including the first body of release, the one end of releasing first body is the link, the link is used for splitting the device and being connected with sending, this internal lou cavity of hopper -shaped that is provided with of release head, the first cavity of cavity splits the device intercommunication with sending, the second cavity of cavity is the enclosed cavity, be provided with a plurality of jet orifices on the lateral wall of second cavity, the axis of jet orifice and the contained angle between the first body central line of release are 45-90, the utility model discloses but wide application in shale gas, coal bed gas and the coal mine gas field of gathering.
Description
Technical field
The utility model can change the release head in fracturing direction, belongs to technical field of new energies, is specifically related to shale gas, coal bed gas and coal mine gas collection.
Background technology
The release head of current fracturing device, direction is changeless, because the coal seam in each colliery and punching angle orientation etc. are different in fracturing process, causes some mine fracturing effect undesirable.
Utility model content
The utility model overcomes the deficiency that prior art exists, and provides the release head in the changed fracturing direction that a kind of fracturing is effective, fracturing efficiency is high.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: the release head that can change fracturing direction, comprise release head body, one end of described release head body is link, described link is used for being connected with fracturing device, funnelform cavity is provided with in described release head body, first cavity of described cavity is communicated with fracturing device, second cavity of described cavity is enclosed cavity, the sidewall of described second cavity is provided with multiple spray-hole, and the angle between the axis of described spray-hole and release head body central line is 45 ° ~ 90 °.
Angle between the axis of described spray-hole and release head body central line is 45 °, or is 90 °.
The beneficial effect that the utility model compared with prior art has is: the release head that the utility model fabrication direction is fixing, directly spray-hole is aimed at coal seam, make gases at high pressure directly act on coal seam, raise the efficiency in fracturing process.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further.
Fig. 1 is structural representation of the present utility model, that is structural representation when jet orifice obliquity is 45 °.
Fig. 2 is structural representation when jet orifice obliquity is 90 ° in the utility model.
In figure: 1 be release head body, 2 be link, 3 to be the first cavity, 5 be that the second cavity, 6 is spray-hole for cavity, 4.
Detailed description of the invention
As shown in Figure 1 and Figure 2, the utility model can change the release head in fracturing direction, comprise release head body 1, one end of described release head body 1 is link 2, described link 2 is for being connected with fracturing device, funnelform cavity 3 is provided with in described release head body 1, first cavity 4 of described cavity 3 is communicated with fracturing device, second cavity 5 of described cavity 3 is enclosed cavity, the sidewall of described second cavity 5 is provided with multiple spray-hole 6, and the angle between the axis of described spray-hole 6 and release head body 1 center line is 45 ° ~ 90 °.
Angle between the axis of described spray-hole 6 and release head body 1 center line is 45 °, or is 90 °.
The utility model can change the release head of corresponding angle according to the angle in coal seam and fracturing hole, make directly spray-hole 6 to be aimed at coal seam in fracturing process, make gases at high pressure directly act on coal seam, raise the efficiency.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-described embodiment, in the ken that those of ordinary skill in the art possess, various change can also be made under the prerequisite not departing from the utility model aim.
