Description
Technical field
The utility model is the kit on oil pumping in oil fields tubing string, is the instrument of hollow stem oil pumping, specifically a kind of
Hollow rod watered check valve.
Background technology
In oil-field thick-oil production, the frictional force between sucker rod and viscous crude, sucker rod upstream and downstream is difficult, recovers the oil conventional
Heavy oil wells can not be produced normally when method is produced, and due to thick poor fluidity, can also block runner, easily cause oil well stopping production.
In the production of oil field thin oil well, some pumpingh well paraffin contents are high, and easily separating out knot on the top of oil pick-up tube is attached to tube inner wall or takes out
On beam hanger, oil flow channel is caused to block, sucker rod is descending to be obstructed, it has to regular wax removal.Current heavy oil wells produce and are typically all
Pumped using to hollow stem, paraffin-troubled well is in wax deposition section using hollow stem oil pumping.Pumped using hollow stem, can be noted in hollow stem
Enter hot water, hot water flows out downwards through hollow rod from linked hole, then through hollow rod and oil pipe annular space to upstream
Go out, hot water is dropped glutinous, wax melting to the viscous crude on tube rod surface and wax deposition heating in cyclic process, make heavy oil wells paraffin-troubled well normal
Production.But when not to hot water is injected in hollow stem, the pressure outside hollow stem is higher than the pressure in hollow stem, the crude oil in oil pipe
Easily enter in hollow stem from the linked hole of hollow stem bottom, into hollow stem in after solidification or wax deposition, block hollow stem, cause
Well-flushing can not be carried out to injection hot water in hollow stem drop glutinous, wax removal again.Chinese patent 200920022728.9《Hollow water-doped single flow
Valve》, can overcome above mentioned problem, but it bears the part of fluid column load and is formed by connecting by two pieces, and reliability is affected.Big
When being used on Wells and horizontal well, its spring, valve ball can drop under Gravitative Loads, cause valve ball to be not closed completely, and lose
The effect for preventing crude oil from flowing backwards.
The content of the invention
The purpose of this utility model is a kind of hollow rod watered check valve of design, makes the crude oil outside its hollow stem will not be from sky
The linked hole of core bar bottom enters in hollow stem, it is ensured that the channels open of injection hot water, and can overcome above-mentioned problem.
What the purpose of this utility model was realized in：Including valve body, circlip, valve seat, valve ball, supporting positive cover, spring,
Screw thread on the upper design hollow stem of valve body, screw thread under the bottom design hollow stem of valve body, the top of valve body communicates with bottom, from
The top of valve body is sequentially placed into spring, supporting positive cover, valve ball, valve seat, and the lower surface of spring is sitting in the inner circular bead of valve body, righting
Spring is entangled, supporting positive cover coordinates spring righting, the outer wall of supporting positive cover with the inwall of valve body, and supporting positive cover is made by valve body righting
Supporting positive cover, the axis of spring are coaxial with valve body, and pushing valve seat makes spring produce pretightning force, and elasticity gear is installed in the endoporus of valve body
Circle, valve seat is seated in another inner circular bead of valve body, and circlip makes valve seat spacing, and valve seat can not be moved up, and supporting positive cover exists
Valve ball is supported in the presence of spring, the aperture with diameter greater than valve seat of valve ball makes valve ball be seated on the lower end valve port of valve seat, valve
Ball and the valve port fitted seal of valve seat, enable liquid stream to flow to lower end from the upper end of valve seat, it is impossible to flow to upper end from the lower end of valve seat,
The top of supporting positive cover sets linked hole, and the stream stream that valve ball is lifted off a seat on rear valve body can flow to valve by described linked hole
The bottom of body.
The beneficial effects of the utility model are：Screw thread on the upper design hollow stem of valve body, the bottom design of valve body is hollow
Screw thread under bar, the top of valve body communicates with bottom, it is may be coupled to the optional position of hollow stem rod string, and bear
The part of fluid column load only has valve body one, and supporting positive cover coordinates spring righting, the outer wall of supporting positive cover with the inwall of valve body, righting
Set makes supporting positive cover, the axis of spring coaxial with valve body by valve body righting, therefore the utility model reliability is high, is adapted in High angle
Used on well and horizontal well, therefore, the utility model overcomes the problem that presently, there are, with significant effect.
Brief description of the drawings
Accompanying drawing 1 is the installation diagram of the utility model embodiment.
Specific embodiment
1 pair of the utility model embodiment is illustrated below in conjunction with the accompanying drawings.
As illustrated, embodiment of the present utility model includes valve body 1, circlip 2, valve seat 3, valve ball 4, supporting positive cover 6, bullet
Spring 7, screw thread 8 on the upper design hollow stem of valve body 1, screw thread 9 under the bottom design hollow stem of valve body 1 can be connected to hollow
On bar rod string, the top of valve body 1 communicates with bottom, from the top of valve body 1 be sequentially placed into spring 7, supporting positive cover 6, valve ball 4,
Valve seat 3（The path of the external diameter less than screw thread 8 on hollow stem of supporting positive cover 6, valve seat 3）, the lower surface of spring 7 is sitting in the interior of valve body 1
On portion's shoulder, supporting positive cover 6 entangles spring 7, and supporting positive cover 6 coordinates the righting of spring 7, the outer wall of supporting positive cover 6 with the inwall of valve body 1,
Supporting positive cover 6 makes supporting positive cover 6, the axis of spring 7 coaxial with valve body 1 by the righting of valve body 1, and pushing valve seat 3 makes spring 7 produce pretension
Power, valve seat 3 is seated in another inner circular bead of valve body 1, and circlip 2 is installed in the endoporus of valve body 1, and circlip 2 makes valve
