Description

Soak by PE pipe and immersible pump or packer jockey and using method a kind ofly

Technical field

The invention belongs to mining using leaching technology PE pipe connection, be specifically related to soak with PE pipe and diving a kind oflyPump or packer jockey and using method.

Background technology

Existing oil packer generally adopts pipe thread seal to be connected with steel pipe, and immersible pump adopts high pressure connectionConnect PE pipe. Although above-mentioned packer is connected simply with tubing round thread, has weak point. Due to packingDevice, in acidity or alkaline environment, needs to adopt stainless steel tube to be connected with it, and cost is high; Immersible pump connects requiredHigh pressure connection cost is high, and complex process.

Summary of the invention

The technical problem that patent of the present invention will solve is: conventional packer or immersible pump are communicated with employing not with groundRust steel pipe cost is high, adopts cheap PE pipe to need to solve and how to connect.

For the problems referred to above, technical scheme of the present invention is: soak with PE pipe and immersible pump or packer a kind oflyJockey, comprises inner tube, narrows and manage and outer screwed pipe; Wherein, inner tube is hollow tubular, and its interface is platformScalariform, inner tube bottom is fixed with flange welding; Lower side has the external screw thread being connected and fixed with the pipe that narrows;Inner tube upper outside face has external screw thread or more piece anti-slip tank; Narrow pipe for hollow tubular, and its top, cross section isFrustum type, upper side has taper thread, and is uniformly distributed 4 road grooves; Pipe frustum type internal diameter and PE pipe narrowExternal diameter coupling; The pipe bottom that narrows has and the internal thread of inner tube lower external thread coupling; Shape inside outer screwed pipeWith the pipe top frustum type coupling that narrows, and its inner side has and the screw thread of the taper thread coupling on the pipe top that narrows.

Described inner tube, the pipe that narrows, outer screwed pipe material are stainless steel.

Above-mentioned soaking comprises following step by the using method of PE pipe and immersible pump or packer jockey a kind oflyRapid:

Step 1, the pipe that will narrow successively, outer screwed pipe are enclosed within on PE pipe;

Step 2, by PE pipe box, outside inner tube, the pipe that will narrow is afterwards connected with Internal Pipe Thread;

Step 3, screws outer screwed pipe narrowing on pipe, when outer screwed pipe further screws, narrow pipe under pressureInwardly shrink, PE pipe is compressed, make it PE pipe be fixed on packer or immersible pump.

Use patent of the present invention can obtain following effect: by this jockey, can be by PE pipe and rigid bodyConnect, can solve packer or immersible pump aspect soaking be communicated with employing stainless steel tube cost with ground high on groundProblem, reduces ground and soaks cost.

Detailed description of the invention

Below in conjunction with drawings and Examples, the present invention is described further.

Soak with PE pipe and immersible pump or a packer jockey, comprise stainless inner tube 1, narrowPipe 2 and outer screwed pipe 3, wherein, inner tube 1 is hollow tubular, its interface is step-like, as shown in Figures 1 to 3,Inner tube 1 bottom and flange 5 are welded and fixed; Lower side has and pipe 2 external screw threads that are connected and fixed that narrow;Inner tube 1 upper outside face has external screw thread or more piece anti-slip tank, plays while managing 4 close contact with PE and plays admittedlyFixed anti-skidding effect; Narrow pipe 2 as shown in Fig. 4～6, is hollow tubular, and its top, cross section is frustum type, onPortion side has taper thread, and is uniformly distributed 4 road grooves, and under nature, epimere becomes the shape that narrows; Pipe 2 narrowsFrustum type internal diameter is managed 4 external diameters with PE and is mated; Narrowing, pipe 2 bottoms have with inner tube 1 lower external thread couplingInternal thread; Outer screwed pipe is 3 inner side shapes and the pipe 2 top frustum type couplings that narrow as shown in Figure 7, and its inner sideHave and the screw thread of the taper thread coupling on pipe 2 tops that narrow.

Assemble sequence is: outer screwed pipe 3, the pipe 2 that narrows are enclosed within on PE pipe 4, in then PE pipe 4 being enclosed withinOutside pipe 1, the pipe that will narrow afterwards 2 is threaded with inner tube 1, and after this outer screwed pipe 3 screws narrowing to manage on 2,Owing to being taper thread, in the time that outer screwed pipe 3 further screws, the pipe 2 that narrows inwardly shrinks under pressure, by PEPipe 4 compresses, thereby PE pipe 4 is fixed on packer or immersible pump.

Taking packer as example, first inner tube 1 is connected with packer by flange 5, then by outer screwed pipe 3, inFootpath is that the 40mm pipe 2 that narrows is enclosed within on PE pipe 4, is the PE pipe that 30mm, external diameter are 40mm afterwards by internal diameter4 are enclosed within inner tube 1 epimere that external diameter is 30mm, and the pipe that will narrow afterwards 2 is threaded with inner tube 1, after this outsideScrewed pipe 3 screws on 2 at the pipe that narrows, and owing to being taper thread, in the time that outer screwed pipe 3 further screws, pipe 2 narrowsUnder pressure, inwardly shrink, PE pipe 4 is compressed, thereby PE pipe 4 is fixed on packer.

Above embodiments of the invention are explained in detail, above-mentioned embodiment is only of the present invention optimum realExecute example, but the present invention is not limited to above-described embodiment, the knowledge possessing those of ordinary skill in the artIn scope, can also under the prerequisite that does not depart from aim of the present invention, make various variations.
