Description
Technical field
The utility model relates to control valve, is specifically related to low sheraing control valve.
Background technology
At present in Extra-high-water-cut stage development process, polymer displacement of reservoir oil is one of major measure improving oil recovery factor, this technique is that certain density polymer solution is injected stratum from well head, by increasing stratum injection liquid viscosity, expanding injection liquid swept volume and improving oil recovery factor.Because each oil field geologic situation is different, the polymer injection rate of each well is also different, this just needs the adjustment being carried out flow by valve, due to the pseudoplastic fluid that injection of polymer is in non-newtonian fluid, if be subject to shearing force in flow process, injection liquid viscosity will be made lower, and very large shearing force can be produced to injecting solution when using traditional valve to carry out Flow-rate adjustment, its viscosity can reduce nearly 40%, has a strong impact on its result of use.Current oil field at home note polymerizing technology flow process adopts single pump to distribute technique to individual well substantially, and adopts the single pumpage of adjustment to regulate injection rate, thus causes pump valve consumption large, and cost of production is high.
Utility model content
Technical problem to be solved in the utility model solves when conventional valves carries out Flow-rate adjustment to produce very large shearing force to injection solution, has a strong impact on the problem of its result of use.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is to provide a kind of low sheraing control valve, comprise valve body and adjusting device, described valve body is straight tube-like, comprise the adjusting portion and valve barrel that arrange successively, feed screw nut is provided with in described adjusting portion, described feed screw nut is installed in draw-in groove suitable with it on adjusting portion inwall, and can around its center axis thereof in described draw-in groove, the front end side wall of described valve barrel and rear end are respectively equipped with water inlet and delivery port, described adjusting device comprises adjustment handle and adjusting rod, described adjustment handle is threaded onto in described adjusting portion and fixes with described feed screw nut, described adjusting rod comprises the installation portion and shaft that arrange successively, described installation portion is arranged in adjusting portion and fills with feed screw nut spiral shell, described shaft is arranged at valve barrel inside, its front end face is concordant with the front end face of described valve barrel, comprise multiple from front to back successively prime minister connect the truncated cone connected with tail tail, all side valve inside wall of cylinder surfaces of the first joint of described shaft are in convex surface suitable with it, all side valve inside wall of cylinder surfaces of described shaft tail tail joint are in concave surface suitable with it.
In such scheme, between described adjusting portion and valve barrel, be provided with sealed letter.
In such scheme, between described sealed letter and adjusting rod, between sealed letter and valve body, be equipped with sealing ring.
In such scheme, described shaft rear end installs and is fixed with guide ring, and described guide ring is provided with the pod apertures that 2 front and back communicate.
The utility model, handle and adjusting rod is regulated because be provided with, the shaft of adjusting rod comprise multiple from front to back successively prime minister connect the truncated cone connected with tail tail, regulate handle adjusting rod can be driven to seesaw by feed screw nut by rotating, thus realize the function being regulated its flow by the cross-sectional area changing its runner, and its flow area changes gradually in the process regulated, the shearing force of generation is very little, can not affect the result of use injecting solution.
Accompanying drawing explanation
Fig. 1 is generalized section of the present utility model;
In figure: 1-adjusting portion, 2-valve barrel, 21-water inlet, 22-delivery port, 3-regulate handle, 4-feed screw nut, 5-installation portion, 6-shaft, 7-sealed letter, 8-guide ring.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, the low sheraing control valve that the utility model provides, comprise valve body and adjusting device, valve body is straight tube-like, comprise the adjusting portion 1 and valve barrel 2 that arrange successively, feed screw nut 4 is provided with in adjusting portion 1, feed screw nut 4 is installed in draw-in groove suitable with it on adjusting portion 1 inwall, and can around its center axis thereof in draw-in groove, the front end side wall of valve barrel 2 and rear end are respectively equipped with water inlet 21 and delivery port 22, sealed letter 7 is provided with between adjusting portion 1 and valve barrel 2, be circular channel in the middle of sealed letter 7, mounting O-shaped sealing ring in passage, passage arranges O RunddichtringO equally.Sealed letter 7 can well prevent injecting solution and reveal from adjusting rod, is equipped with sealing ring, further enhancing its sealing between sealed letter 7 and adjusting rod, between sealed letter 7 and valve body.Adjusting device comprises adjustment handle 3 and adjusting rod, regulate handle 3 to be threaded onto in adjusting portion 1 to fix with feed screw nut 4, adjusting rod comprises the installation portion 5 and shaft 6 that arrange successively, installation portion 5 is arranged in adjusting portion 1 and fills with feed screw nut 4 spiral shell, it is inner that shaft 6 is arranged at valve barrel 2, its front end face is concordant with the front end face of valve barrel 2, comprise multiple from front to back successively prime minister connect the truncated cone connected with tail tail, all side valve cylinder 2 inner wall surface of the first joint of shaft 6 are in convex surface suitable with it, all side valve cylinder 2 inner wall surface of shaft 6 tail tail joint are in concave surface suitable with it.Shaft 6 rear end installs and is fixed with guide ring 8, and guide ring 8 is provided with the pod apertures that 2 front and back communicate.
When needs adjust flux, first rotate and regulate handle 3, thus drive the feed screw nut 4 fixing with it to rotate, be installed in due to feed screw nut 4 again in the draw-in groove on adjusting portion 1 inwall and can not move forward and backward, so feed screw nut 4 will drive the adjusting rod of spiral shell dress with it to move forward and backward while rotating.When adjusting rod moves forward and backward, due to shaft 6 by multiple from front to back successively prime minister connect the truncated cone connected with tail tail and form, and all side valve cylinder 2 inner wall surface of the first joint of shaft 6 are in convex surface suitable with it, all side valve cylinder 2 inner wall surface of shaft 6 tail tail joint are in concave surface suitable with it, the cross-sectional area of runner can be made to change so shaft 6 is movable, thus realize the function changing flow.The utility model, handle 3 and adjusting rod is regulated because be provided with, the shaft 6 of adjusting rod comprise multiple from front to back successively prime minister connect the truncated cone connected with tail tail, regulate handle 3 adjusting rod can be driven to seesaw by feed screw nut 4 by rotating, thus realize the function being regulated its flow by the cross-sectional area changing its runner, and its flow area changes gradually in the process regulated, the shearing force of generation is very little, can not affect the result of use injecting solution.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structure change made under enlightenment of the present utility model, and every have identical or close technical scheme with the utility model, all falls within protection domain of the present utility model.
