Abstract
The invention provides a manual wedge-shaped throttle valve, belongs to the field of oil well pressure control and aims to enhance the transverse force bearing capacity of a valve core and increase the safety coefficient of the throttle valve. The technical scheme includes that the manual wedge-shaped throttle valve comprises a valve seat, a valve core and a shell, the valve core is a cylinder with one side edge clinging to the inner wall of the valve seat, and flow guide buffer surfaces are arranged on the front section of the valve core. Since one side of the valve core clings to the inner wall of the valve seat, the valve core cannot vibrate after being impacted by fluid, the transverse force of the fluid on the valve core is reduced by the aid of the flow guide surfaces, possibility of breakage of the valve core is greatly decreased, oil well blowout is avoided, and safety of oil well operation is improved; by the aid of a concave cambered surface arranged between the inclined flow guide surface and the axial flow guide surface, anti-erosion capability of the valve core is enhanced, and service life of the valve core is prolonged.
Description
Technical field
The present invention relates to a kind of wedge shape manual throttle valve.
Background technique
Employed throttle valve comprises valve seat, spool and housing on the existing oil well pipeline, and wherein, spool is needle-like, the front end of spool is conical surface, and be in vacant state between the valve seat, in use, spool produces easily after being subject to the horizontal force of fluid and swings, cause the spool slippage, even can make the spool fracture, in high-pressure gas well, because the throttle valve downstream shows without pressure, the spool fracture can not in time be found, great Blowout firing accident will occur.
Summary of the invention
The present invention proposes a kind of wedge shape manual throttle valve, can improve the horizontal force strength of spool, improves the safety coefficient of throttle valve.
Technological scheme of the present invention is achieved in that a kind of wedge shape manual throttle valve, comprises valve seat, spool and housing, described spool be a side and valve base inner wall near cylinder; Described spool front end is provided with the water conservancy diversion buffering suface.
Described water conservancy diversion buffering suface comprises the oblique guide face and the axial diversion face that is connected oblique guide face over against entrance.
Further, also be provided with a spill cambered surface between described oblique guide face and the axial diversion face; The oblique guide face of spill cambered surface smooth connection and axial diversion face.
Optimize, the gradient of described oblique guide face is 30 degree.
The invention provides a kind of wedge shape manual throttle valve, one side and the valve base inner wall of spool are close to, after making spool by fluid impact, can not produce vibration, by guide face is set, reduced the horizontal force of fluid to spool, greatly reduce the possibility of spool fracture, avoid the generation of oil-well blowing event, improved the Security of oil well operation; The spill cambered surface that tiltedly arranges between guide face and the axial diversion face, the fluid erosion prevention ability of raising spool, the working life of improving spool.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1: structural representation of the present invention;
Wherein: 1-spool, 2-valve seat, 3-oblique guide face, 4-spill cambered surface, 5-axial diversion face, 6-entrance, 7-outlet.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technological scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiments.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment who obtains under the creative work prerequisite.
A kind of wedge shape manual throttle valve provided by the invention, its technological scheme is achieved in that a kind of wedge shape manual throttle valve, comprises valve seat 2, spool 1 and housing, described spool 1 be a side and valve seat 2 inwalls near cylinder; Described spool 1 front end is provided with the water conservancy diversion buffering suface.Described water conservancy diversion buffering suface comprises the oblique guide face 3 and the axial diversion face 5 that is connected oblique guide face 3 over against entrance 6.Further, also be provided with a spill cambered surface 4 between described oblique guide face 3 and the axial diversion face 5; The oblique guide face 3 of spill cambered surface 4 smooth connections and axial diversion face 5.Optimize, the gradient of described oblique guide face 3 is 30 degree.
Such as Fig. 1 structural representation of the present invention, a side of spool 1 and valve seat 2 inwalls are close to, and when fluid high-speed impacted spool 1, spool 1 can not produce vibration, to such an extent as to spool 1 fracture; In use, fluid impacts first the oblique guide face 3 of spool 1, and tiltedly guide face 3 convection cells cushion, and warp beam flows out to guide face 5 again, effectively reduces liquid to the lateral impact forces of spool 1; Usually, the surface that contacts with high-velocity fluid is more smooth, the fluid erosion prevention ability is higher, the spill cambered surface 4 that tiltedly arranges between guide face 3 and the axial diversion face 5, make oblique guide face 3 and 5 smooth connections of axial diversion face, greatly improve the fluid erosion prevention ability of spool 1, improved the use of spool 1 and used, guaranteed the safety of oil well work.
In use, high-speed liquid enters by entrance 6, directly impacts the oblique guide face 3 of throttle valve, because the opposite side of spool 1 and valve seat 2 inwalls are close to, so spool 1 can not produce vibration, high-velocity fluid flows out via axial diversion face 5, outlet 7 after impacting oblique guide face 3.
The angle of inclination of oblique guide face of the present invention is 30 degree, and namely tiltedly guide face becomes 30 degree with the acute angle that horizontal guide face forms.Can effectively reduce the lateral impact forces of liquid.
The invention provides a kind of wedge shape manual throttle valve, one side of spool 1 and valve seat 2 inwalls are close to, make spool 1 by behind the fluid impact, can not produce vibration, by guide face is set, reduced the horizontal force of fluid to spool 1, greatly reduce the possibility of spool 1 fracture, avoid the generation of oil-well blowing event, improved the Security of oil well operation; The spill cambered surface 4 that tiltedly arranges between guide face 3 and the axial diversion face 5, the fluid erosion prevention ability of raising spool 1, the working life of improving spool 1.
Certainly; in the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art should make according to the present invention various corresponding changes and distortion, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
