Description
Technical field
The utility model relates to control valve, is specifically related to low shearing 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 to stratum from well head, by increasing stratum injection liquid viscosity, expands injection liquid swept volume and improves oil recovery factor.Because each oil field geologic situation is different, the polymer injection rate of each well is also different, this just need to carry out by valve the adjusting of flow, because injection of polymer is the pseudoplastic fluid in non-newtonian fluid, if be subject to shearing force in flow process, will make injection liquid viscosity lower, and can produce very large shearing force to injecting solution while using conventional valve to carry out Flow-rate adjustment, it is nearly 40% that its viscosity can reduce, and has a strong impact on its result of use.Oil field at home note polymerizing technology flow process adopts single pump to distribute technique to individual well substantially at present, and adopts the single pumpage of adjusting to regulate injection rate, thereby causes pump valve consumption large, and cost of production is high.
Utility model content
Technical problem to be solved in the utility model is can produce very large shearing force to injecting solution when solving conventional valves and carrying out Flow-rate adjustment, have 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 shearing control valve, comprise valve body and adjusting device, described valve body is straight tube-like, the conciliation portion and the valve barrel that before and after comprising successively, arrange, in described adjusting portion, be provided with feed screw nut, described feed screw nut is installed on adjusting portion inwall in suitable with it draw-in groove, and can in described draw-in groove, around its central axis, rotate, 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 adjusting handle and adjusting rod, described adjusting handle is threaded onto in described adjusting portion and fixes with described feed screw nut, installation portion and shaft that described adjusting rod arranges before and after comprising 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 a plurality of from front to back successively prime minister connect the truncated cone of joining with tail tail, all side valve inside walls of cylinder surface of the first joint of described shaft is suitable with it convex surface, all side valve inside walls of cylinder surface of described shaft tail tail joint is suitable with it concave surface.
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, be equipped with sealing ring between sealed letter and valve body.
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, because be provided with, regulate handle and adjusting rod, the shaft of adjusting rod comprise a plurality of from front to back successively prime minister connect the truncated cone of joining with tail tail, by rotation, regulate handle can drive adjusting rod to seesaw by feed screw nut, thereby realize, by changing the cross-sectional area of its runner, regulate the function of its flow, and its flow area changes gradually in the process regulating, and the shearing force of generation is very little, can not affect the result of use of 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-adjusting handle, 4-feed screw nut, 5-installation portion, 6-shaft, 7-sealed letter, 8-guide ring.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, the low shearing control valve that the utility model provides, comprise valve body and adjusting device, valve body is straight tube-like, the conciliation portion 1 and the valve barrel 2 that before and after comprising successively, arrange, in adjusting portion 1, be provided with feed screw nut 4, feed screw nut 4 is installed on adjusting portion 1 inwall in suitable with it draw-in groove, and can in draw-in groove, around its central axis, rotate, the front end side wall of valve barrel 2 and rear end are respectively equipped with water inlet 21 and delivery port 22, between adjusting portion 1 and valve barrel 2, be provided with sealed letter 7, in the middle of sealed letter 7, it is circular channel, mounting O-shaped sealing ring in passage, passage arranges O RunddichtringO equally.Sealed letter 7 can well prevent from injecting solution and reveal from adjusting rod, between sealed letter 7 and adjusting rod, be equipped with sealing ring between sealed letter 7 and valve body, has further strengthened its sealing.Adjusting device comprises adjusting handle 3 and adjusting rod, regulate handle 3 to be threaded onto in adjusting portion 1 fixing with feed screw nut 4, installation portion 5 and shaft 6 that adjusting rod arranges before and after comprising successively, installation portion 5 is arranged in adjusting portion 1 and fills with feed screw nut 4 spiral shells, shaft 6 is arranged at valve barrel 2 inside, its front end face is concordant with the front end face of valve barrel 2, comprise a plurality of from front to back successively prime minister connect the truncated cone of joining with tail tail, all side valve cylinder 2 inner wall surface of shaft 6 first joints are suitable with it convex surface, all side valve cylinder 2 inner wall surface of shaft 6 tail tail joints are suitable with it concave surface.Shaft 6 rear ends install and are 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, thereby drive the feed screw nut fixing with it 4 to rotate, because feed screw nut 4 is installed in the draw-in groove on conciliation portion 1 inwall, can not move forward and backward again, so when rotating, feed screw nut 4 will drive the adjusting rod of spiral shell dress with it to move forward and backward.When adjusting rod moves forward and backward, due to shaft 6 by a plurality of from front to back successively prime minister connect the truncated cone of joining with tail tail and form, and all side valve cylinder 2 inner wall surface of shaft 6 first joints are suitable with it convex surface, all side valve cylinder 2 inner wall surface of shaft 6 tail tail joints are suitable with it concave surface, so shaft 6 moves forward and backward, can make the cross-sectional area of runner change, thereby realize the function that changes flow.The utility model, because be provided with, regulate handle 3 and adjusting rod, the shaft 6 of adjusting rod comprise a plurality of from front to back successively prime minister connect the truncated cone of joining with tail tail, by rotation, regulate handle 3 can drive adjusting rod to seesaw by feed screw nut 4, thereby realize, by changing the cross-sectional area of its runner, regulate the function of its flow, and its flow area changes gradually in the process regulating, and the shearing force of generation is very little, can not affect the result of use of injecting solution.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, within all falling into protection domain of the present utility model.
