Description
Technical field
The utility model relates to technical field of petroleum machinery, is specifically related to one and surges orifice control valve.
Background technique
In Process of Oil Well Drilling, every mouthful of well all must install a set of throttling well killing device, in order to control well downforce, reach the safe condition of near-balance drilling, throttling well killing device is made up of choke manifold and kill manifold, down-hole pressure controls to be completed by choke manifold, throttle valve is the crucial control piece of choke manifold, the choke manifold throttle valve used of existing use is barrel throttle, has the following disadvantages: barrel throttle easily, flow control inaccuracy short by down-hole air-flow erosion failure, working life, throttling time vibrations greatly, not steady; Can not implement to close completely.
The working principle of existing throttle valve be by before a valve rod with a cylinder or needle-like head, outlet is blocked by the rotation of handwheel, thus change throttling bore reaches restriction effect, but the valve of this kind of structure can not thoroughly be closed, external gate valve in the loop closed is needed to close loop circuit.
Model utility content
Technical problem to be solved in the utility model overcomes defect of the prior art, provides one to surge orifice control valve, can not only thoroughly close, and can remote operation, safe and reliable.
For solving the problems of the technologies described above, the utility model provides one to surge orifice control valve, comprise valve body, valve seat, valve plate, valve rod and valve gap, valve body is T-shaped three-port structure, outlet(discharge) flange is provided with in the bottom of valve body, the top of valve body is connected with valve gap, valve seat is provided with in valve body, the valve pocket that valve rod runs through in valve body is connected with valve plate, valve plate comprises upper valve plate and the lower valve plate of concentric setting, upper valve plate and lower valve plate are that disc type plane is connected, the lower surface of upper valve plate contacts with the upper surface of lower valve plate, upper valve plate and lower valve plate are axially respectively provided with a through hole, two valve plates are arranged in valve seat, the underpart of valve rod is connected with upper valve plate, the upper end portion of valve rod is connected with transmission shaft, the upper end portion of transmission shaft is connected with the head that surges.
As further improvement of the utility model, the shape of through hole is semicircle.
The beneficial effect that the utility model reaches is: the orifice control valve that surges of the present utility model can throttling, can stop again, can reduce installation flashboard valve, greatly save equipment investment.Valve plate selects the stainless steel through supersonic spray coating process, and when throttle valve cuts out, valve plate normally can work under the pressure of 105Mpa, adopts the head that surges, can realize remote operation, avoids the danger of artificial under high pressure manually-operable throttle valve.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the plan view of valve plate.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in the figure, the utility model provides one to surge orifice control valve, comprise valve body 5, valve seat 2, upper valve plate 4, lower valve plate 3, valve rod 6 and valve gap 7, valve body 5 is T-shaped three-port structure, the bottom of valve body 5 is provided with outlet(discharge) flange 1, top is connected with valve gap 7, valve seat 2 is installed in valve body 5, the valve pocket that valve rod 6 runs through in valve body 5 is connected with valve plate, valve plate is placed in valve seat 2, valve plate comprises upper valve plate 4 and the lower valve plate 3 of concentric setting, upper valve plate 4 is connected in disc type plane with lower valve plate 3, the lower surface of upper valve plate 4 contacts with the upper surface of lower valve plate 3, upper valve plate 4 and lower valve plate 3 are axially respectively provided with a semi-circular through hole 11, the underpart of valve rod 6 is connected with upper valve plate 4, the upper end portion of valve rod 6 is connected with transmission shaft 8, the upper end portion of transmission shaft 89 to be connected with surging.
Normal working, valve wide open; When needing throttling, by surging, a 9 drive transmission shaft 8 rotates clockwise, valve rod 6 rotates thereupon and drives valve plate 4 to rotate, the semicircle orifice of the semicircle orifice of lower valve plate 3 and upper valve plate 4 is staggered gradually, valve starts throttling, and progressively reduce flow, and when the semicircle orifice that valve rod 6 is rotated further lower valve plate 3 is blocked by upper valve plate 4 completely, valve closing.
When needing Open valve, a 9 drive transmission shaft 8 that surge rotate counterclockwise, valve rod 6 rotates thereupon and drives valve plate 4 to rotate, the semicircle orifice of the semicircle orifice of lower valve plate 3 and upper valve plate 4 is staggered gradually, valve starts throttling, and progressively enlargement discharge, when valve rod 6 is rotated further the semicircle orifice of lower valve plate 3 and upper valve plate 4 semicircle orifice blocks timing completely, valve wide open.
Only preferred implementation of the present utility model described in upper; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
