Abstract
The utility model discloses a throttle valve, which comprises a valve seat, a valve core and a shell, and is characterized in that a diversion inclined plane and a diversion horizontal plane are arranged on the front portion of the valve core, the diversion horizontal plane is arranged on the front end of the valve core, the diversion inclined plane is arranged on the rear side of the diversion horizontal plane, and the lower end of the diversion inclined plane and the diversion horizontal plane are crossly arranged. Because of adopting the technical scheme, the throttle valve has the advantages of convenient machining, strong popularity and strong erosion resistance ability, enables fluid in big and small flow to generate vortex after flowing out through the valve core, reduces lateral force, reduces vibration, prevents the valve core from fracturing, and avoids blowout fire accidents.
Description
Technical field
The utility model relates to the parts on a kind of oil well pipeline, particularly a kind of choke valve.
Background technology
Employed choke valve comprises valve seat, spool and housing on the existing oil well pipeline, and wherein, spool is a column, and the front end of spool is the inclined-plane; In use, under big flow, fluid can directly impact on spool, and the inclined-plane by the spool front end flows out again; Its horizontal force is bigger, and judder can take place in the whirlpool slippage; Valve seat, spool and housing are washed out by fluid easily, even can make the spool fracture, in high-pressure gas well; Because the choke valve downstream do not have pressure display, the spool fracture can not in time be found, great blowout firing accident will take place.
The utility model content
The purpose of the utility model just provides a kind of easy to process, highly versatile and the strong choke valve of anti-impact erosion ability; It can make the fluid under the large and small flow flow out back generation whirlpool through spool, reduces horizontal force, reduces vibration; Prevent the spool fracture, avoid taking place the blowout firing accident.
The purpose of the utility model is to realize through such technical scheme; It includes valve seat, spool and housing; It is characterized in that: be provided with water conservancy diversion inclined-plane and water conservancy diversion horizontal plane in the spool front portion; The water conservancy diversion horizontal plane is positioned at the front end of spool, and the water conservancy diversion inclined-plane is positioned at the rear side of water conservancy diversion horizontal plane, and the lower end on water conservancy diversion inclined-plane and water conservancy diversion horizontal plane intersect.
The utility model in use after fluid under big flow or the low discharge is through the water conservancy diversion inclined-plane on the spool, is flowed out by the water conservancy diversion horizontal plane on the spool again; The water conservancy diversion inclined-plane can reduce the direct impact of fluid to spool; The water conservancy diversion horizontal plane can make fluid form whirlpool in the place ahead of spool, has reduced horizontal force, has reduced vibration; Prevent the spool fracture, avoided taking place the blowout firing accident.
Owing to adopted technique scheme; The utlity model has the strong advantage of easy to process, highly versatile and anti-impact erosion ability; It can make the fluid under the large and small flow flow out back generation whirlpool through spool, has reduced horizontal force, has reduced vibration; Prevent the spool fracture, avoided taking place the blowout firing accident.
Description of drawings
The description of drawings of the utility model is following.
Fig. 1 is the structural representation of the utility model.
The sketch map that fluid flowed when Fig. 2 was the utility model use.
Among the figure: the ⒈ valve seat; The ⒉ spool; The ⒊ housing; ⒋ water conservancy diversion inclined-plane; ⒌ water conservancy diversion horizontal plane.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
As shown in Figure 1; The utility model comprises valve seat 1, spool 2 and housing 3; It is characterized in that: be provided with water conservancy diversion inclined-plane 4 and water conservancy diversion horizontal plane 5 in spool 2 front portions; Water conservancy diversion horizontal plane 5 is positioned at the front end of spool 2, and water conservancy diversion inclined-plane 4 is positioned at the rear side of water conservancy diversion horizontal plane 5, and the lower end on water conservancy diversion inclined-plane 4 and water conservancy diversion horizontal plane 5 intersects.
The direction of arrow as shown in Figure 2 is the direction that fluid flows, the utility model in use, after fluid under big flow or the low discharge is through the water conservancy diversion inclined-plane 4 on the spool; Flowed out by the water conservancy diversion horizontal plane on the spool 2, the water conservancy diversion inclined-plane can reduce the direct impact of fluid to spool again, and the water conservancy diversion horizontal plane can make fluid form whirlpool in the place ahead of spool; Reduced horizontal force; Reduce vibration, prevented the spool fracture, avoided taking place the blowout firing accident.Described fluid can be oil, drilling fluid or mud.
