With Yinxing Technology Development Co., Shengli Oil Field " CN02247698.9 Hydraulic vortex sand separator " and Jinkeyuan Petroleum Engineering Technology Service Co., Ltd., Dagang District, T " CN200420029723.6 Vortex sand separator " it is traditional sub-sand technological means of representative, spiral sub-sand pattern also exists that flow is slow, the defect of easy deterioration, needs in actual applications frequently to change sand separator, it more difficult to the crude oil being applicable to page rock extracts.

Summary of the invention

The defect existed for the tradition easy deterioration of sand separator, this utility model is directed to a kind of use flow single flow sand dividing device big, easily detachable.

This utility model solves its technical problem and be employed technical scheme comprise that :

A kind of single flow sand dividing device, including flap type, four-way, flange, connecting tube, screen casing, securing member and sealing member, described sand dividing device is pipeline merogenesis composite construction, and at pipeline, import department is provided with four-way 1 Joint, at four-way 1 The left interface of joint is provided with the double flange of reducing 1 , interface is provided with blind flange thereon 1 , its right interface is provided with the double flange of reducing 2 , its lower interface is provided with flap type, the double flange of reducing 2 The port of export and connecting tube 2 Arrival end is fastenedly connected, in connecting tube 2 Interior set the most mutually is provided with tube screen pipe, connecting tube 2 The port of export and four-way 2 Left interface is tight Gu link, at four-way 2 Right interface be provided with the double flange of reducing 4 , the double flange of reducing 4 Exit connect have blind flange block up 1 , interface is provided with blind flange thereon 2 , its lower interface is provided with the double flange of reducing 3 。

Being arranged with by-pass shunt pipeline in parallel with sub-sand main line, it is by four-way 3 , connecting tube 1 And four-way 4 It is composed in series, wherein four-way 3 A left side and lower interface connect blind flange respectively 1 Block up with blind flange 2 , upper interface is fastenedly connected with flap type outlet, right interface and connecting tube 1 Import is fastenedly connected, connecting tube 1 Outlet and four-way 4 Left interface connects, four-way 4 Right interface connect blind flange block up 2 , lower interface flange double with reducing 1 It is fastenedly connected.

Described four-way 3 The outlet of upper interface and flap type be fastenedly connected, four-way 2 And four-way 4 Between be provided with the double flange of reducing 3 It is connected.

Described flap type is one manual, pneumatic, electronic, that surge.

Described tubulose screen casing concentric is disposed through the double flange of reducing 2 , connecting tube 2 Flanges double with reducing 4 In cavity body.

The beneficial effects of the utility model are: changing traditional product spiral sub-sand pattern, not only flow is big, quick detachable, and service life is long, is more suitable for the crude oil pipeline of page rock.

Detailed description of the invention

This utility model is to scheme 1 As most preferred embodiment specific implementation method is described:

Due to the sandstone composition in crude oil, varying diameters, after the long distance delivery process of pipeline, often show as the tiny composition of diameter under, thick composition is upper, traditional spiral sub-sand pattern is under centrifugal action, the sandstone of BOP deposition is prone to wear out for screw, and for page rock recovery well, conventional art is just more difficult to be suitable for.

This utility model then have employed screen casing 22 Core negative pressure extracting mode, carries out sandstone filtration, and the sandstone of BOP deposition, along with the punching press of pipeline imported crude oil, is constantly pushed to front along BOP, and the lighter oil reservoir of proportion is constantly by the screen casing of core 22 Siphon away, until sandstone overstocks to blocking screen casing 22 Filtering holes, screen casing 22 Interior flow reduction, now, only need to open flap type 13 , open the by-pass shunt pipeline flow dividing be arrangeding in parallel with sub-sand main line, dismounting filter pipeline is replaced or cleans simultaneously, just can come into operation from newly.

As can be seen here, compared with conventional helical formula sub-sand pattern, the frictional force that this utility model pipeline inner wall bears reduces, there is not the helical cut power to sandstone, therefore crude oil is single flow, for traditional filtering mode, not only flow is big, and Crude Oil Transportation ability strengthens, and pipeline extends service life.

The foregoing is only a preferred embodiment of the present utility model, it is impossible to limit protection domain of the present utility model with it , This utility model also can have other structure to change , As long as the impartial change made according to protection domain of the present utility model and modification , All should belong in the range of this utility model contains.
