Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
See Fig. 1, it illustrates the anti-bleed device 100 according to the utility model embodiment.Anti-bleed device 100 comprises valve seat body 10, blind plate 20 and air guide orifice plate 30.Blind plate 20 and air guide orifice plate 30 are spaced apart and arranged in the inner chamber 11 of valve seat body 10, and blind plate 20 is closer to the bottom of valve seat body 10, and air guide orifice plate 30 can move around along the internal chamber wall 12 of valve seat body 10.In an example of the present utility model, the bottom of valve seat body 10 is the port of export of anti-bleed device 100 gas when air guide; The top of valve seat body 10 is the link with the sleeve valve (not shown) of the christmas tree of the natural gas well, in use, oil in the christmas tree of the natural gas well and/or gas are flowed in the inner chamber 11 of valve seat body 10 by the top of valve seat body 10, and the bottom of the top of valve seat body 10 and valve seat body 10 is oppositely arranged.
In another example of the present utility model, the external surface on the top of valve seat body 10 is provided with screw thread 13, the top of valve seat body 10 is connected with the sleeve valve of the christmas tree of the natural gas well by screw thread 13.Those skilled in the art can understand, screw thread 13 on the external surface on the top of valve seat body 10 matches each other with the sleeve valve of christmas tree, certainly it will be appreciated by those skilled in the art that, valve seat body 10 can also be connected by the mode such as buckle, welding, as long as anti-bleed device 100 can be realized to be connected on christmas tree.
The inner chamber 11 of valve seat body 10 runs through valve seat body 10, and air guide orifice plate 30 and blind plate 20 are spaced apart and arranged in the inner chamber 11 of valve seat body 10.Particularly, bottom from the top of valve seat body 10 to valve seat body 10 is disposed with air guide orifice plate 30 and blind plate 20 inner chamber 11, air guide orifice plate 30 is placed in inner chamber 11 along the direction of the longitudinally perpendicular to inner chamber 11, and blind plate 20 in the process of air guide for be placed in inner chamber 11 obliquely, air guide orifice plate 30 and blind plate 20 respectively with inner chamber 11 matched in clearance of valve seat body 10, and can freely activity.Simultaneously, air guide orifice plate 30 is also provided with the gas port 31 for ventilating, make the gas in christmas tree can flow in the inner chamber 11 between air guide orifice plate 30 and blind plate 20 by gas port 31 like this, flow to the bottom of valve seat body 10 by the gap between blind plate 20 and internal chamber wall 12 afterwards and flow out anti-bleed device 100, thus achieving the air guide of christmas tree by anti-bleed device 100.
In an also example of the present utility model, the cross sectional shape of inner chamber 11 is circular, in order to the coordinating of inner chamber 11, air guide orifice plate 30 and blind plate 20 are all set to circle, can also in the process of the anti-bleed of anti-bleed device 100, make blind plate 20 realize the bottom of shutoff air guide orifice plate 30 and valve seat body 10 successively by such setting.Certain those skilled in the art can understand, the shape on the top of valve seat body 10 is set to the shape matched with christmas tree, and the inner chamber of valve seat body 10 can be arranged as required accordingly, such as can be set to cuboid, square or cone, this example is only a kind of illustrated examples, and those skilled in the art not should be understood to one restriction of the present utility model.
Shown in composition graphs 1 to Fig. 3, in an example of the present utility model, air guide orifice plate 30 is provided with at least one support bar 32 extended towards the top of valve seat body 10, and support bar 32 is arranged in the installing hole (not shown) on air guide orifice plate 30.In the process of anti-bleed, because the pressure of the oil in christmas tree is comparatively large, air guide orifice plate 30 is easily thrown, thus anti-bleed cannot be realized.By arranging four support bars 32 be evenly arranged along air guide orifice plate 30 circumferential direction to realize the guiding to air guide orifice plate 30 on air guide orifice plate 30, thus in the process of anti-bleed, can move along the internal chamber wall 12 of valve seat body 10 when air guide orifice plate 30 is applied pressure by the oil in christmas tree.Those skilled in the art can understand, support bar 32 can be set to 2,5 or more, leads as long as can be embodied as air guide orifice plate.
When anti-bleed, air guide orifice plate 30 is pushed to the bottom of valve seat body 10 by the oil come from christmas tree from the side, top of valve seat body 10, in the process, after air guide orifice plate 30 is pushed to blind plate 20 and contacts with blind plate 20, make blind plate 20 by righting, and laminating airtight with air guide orifice plate 30, so that the oil in the inner chamber section between the top of valve seat body 10 to air guide orifice plate 30 is blocked in this inner chamber section, along with the top of valve seat body 10 gets more and more to the oil in the inner chamber section between air guide orifice plate 30, air guide orifice plate 30 is pushed together with blind plate 20 to the bottom of valve seat body 10, make the airtight laminating in bottom of blind plate 20 and valve seat body 10, the i.e. shutoff outlet of valve seat body 10, thus achieve anti-bleed, thus avoid due to unexpected power failure, the oil pumper that belt of oil pumping machine ruptures suddenly or other emergency case causes stops taking out, subsurface pressure is high, the bleed phenomenon that the reasons such as disconnected liquid level is high occur, and decrease the environment pollution caused thus.
In the process realizing air guide and anti-bleed, anti-bleed device 100 is a kind of special-shaped one way valve, and it can only make medium flow to a direction, and gas can only be made to pass through, comparatively glutinous fluid (such as crude oil) then not by.In the process realizing anti-bleed, in order to improve the performance of the anti-bleed of anti-bleed device 100, between blind plate 20 and valve seat body 10, be provided with O-ring seal 14.Shown in composition graphs 3 and Fig. 4, O-ring seal 14 is set in the radial direction of the inner chamber 11 along valve seat body 10 on the bottom of valve seat body 10 on projecting inward ring-shaped step 15.
The beneficial effect of the technical scheme that the utility model provides is:
(1) by air guide orifice plate, provide anti-bleed device of the utility model is arranged so that anti-bleed device can only can not be made comparatively to stick fluid and pass through by gas, thus avoid sleeve pipe generation bleed, and then decreases environment pollution;
(2) the anti-bleed device that the utility model provides can also be avoided causing in well building the pressure, and causes oil level to reduce, thus affects the normal production in oil field.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
