Abstract
The utility model relates to a wellhead visual flow control valve, which is composed of a valve body (1), an inlet pipe (9) and an output pipe (10). The valve body (1) is arranged on the end of the inlet pipe (9). The valve body is provided with a piston switch device composed of a piston (5), a sealing ring (4) and a spring (3). An indicator (8) is arranged in the chamber of an outlet tube (19) vertical with the inlet pipe. The indicator is composed of a finger, a central axis and a deflecting plate. The finger is connected with the deflecting plate through the central axis. The deflecting plate is arranged in the chamber of the outlet tube axially. Through the indicator, the utility model renders the flow control valve visual function, thus making users able to watch the flowing direction of liquid clearly. Especially in the production of single-flow oil pipe and water-penetration pipe in oil field, the utility model greatly lowers the loss caused by the reverted flow of liquid.
Description
One, technical field:
The utility model relates to the ball-and-seat of the induction system of a kind of oil, chemical industry, fuel feeding, water supply line liquid, particularly relates to the visual flow valve of a kind of well head.
Two, background technology:
Existing ball-and-seat is widely used, but the problem of its existence is: do not design visual function, be difficult to see the flow direction of liquid from the valve body outward appearance, particularly in the production of oil field single current collector tubing, water permeating pipeline, liquid refluence meeting brings no small loss to production.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of visual flow valve of well head that possesses visual function is provided.
Its technical scheme is: by valve body (1), inlet tube (9) and outlet (10) are formed, the end of described inlet tube (9) is provided with valve body (1), be provided with the piston switch device in the valve body, described piston switch device is by piston (5), sealing ring (4) and spring (3) are formed, outlet (10) inner chamber perpendicular with inlet tube is provided with indicating device (8), described indicating device is by pointer (7), central axis (11) and deflecting plate (12) are formed, pointer (7) is connected with deflecting plate by central axis, and described deflecting plate (12) radially is arranged on the inner chamber of outlet.
Described indicating device (8) is arranged on the inner chamber of outlet by alignment pin (13).
Described deflecting plate (12) is set to the sealing plate of folk prescription to rotation.
The beneficial effects of the utility model are: by being provided with indicating device, thereby make flow valve possess visual function, can be clearly seen that the flow direction of liquid from the valve body outward appearance, particularly in the production of oil field single current collector tubing, water permeating pipeline, greatly reduce the loss that liquid refluence meeting brings to production.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is sectional views of A-A of the present utility model.
Five, the specific embodiment:
In conjunction with the accompanying drawings, the utility model will be further described:
Its technical scheme is: by valve body 1, inlet tube 9 and outlet 10 are formed, the end of described inlet tube 9 is provided with valve body 1, be provided with the piston switch device in the valve body, described piston switch device is by piston 5, sealing ring 4 and spring 3 are formed, outlet 10 inner chambers perpendicular with inlet tube are provided with indicating device 8, described indicating device is by pointer 7, central axis 11 and deflecting plate 12 are formed, pointer 7 is connected with deflecting plate by central axis, described deflecting plate 12 radially is arranged on the inner chamber of outlet, end cap 14 seals, with deflecting plate and central axis tight seal.Described indicating device 8 is arranged on the inner chamber of outlet by alignment pin 13.Described deflecting plate 12 is set to the sealing plate of folk prescription to rotation, liquid can only be flowed out to the outlet direction, and can not flow backwards.
During use, when the liquid in the pipeline was normally carried, the pressure of inlet tube was greater than the pressure of outlet, and liquid promotes to move on the piston, makes opening of valves, and liquid enters in the outlet by valve body smoothly, and simultaneously, flow direction is shown by indicating device;
When liquid stopped in the pipeline, the pressure of inlet tube was less than the pressure of outlet, and piston is by the active force of spring, descendingly close voluntarily, in order to prevent that liquid flows backwards in the pipeline, the deflecting plate in the indicating device can only unidirectionally rotate to the liquid outlet direction, has avoided the liquid refluence.
Claims (3)
1. visual flow valve of well head, by valve body (1), inlet tube (9) and outlet (10) are formed, the end of described inlet tube (9) is provided with valve body (1), be provided with the piston switch device in the valve body, described piston switch device is by piston (5), sealing ring (4) and spring (3) are formed, it is characterized in that: outlet (10) inner chamber perpendicular with inlet tube is provided with indicating device (8), described indicating device is by pointer (7), end cap (14) central axis (11) and deflecting plate (12) are formed, pointer (7) is connected with deflecting plate by central axis, and described deflecting plate (12) radially is arranged on the inner chamber of outlet.
2. the visual flow valve of well head according to claim 1 is characterized in that: described indicating device (8) is arranged on the inner chamber of outlet by alignment pin (13).
3. the visual flow valve of well head according to claim 1 and 2 is characterized in that: described deflecting plate (12) is set to the sealing plate of folk prescription to rotation.
