Abstract
The utility model belongs to a mechanical product, which is mainly used as a control device for delivering crude oil or other liquids to solve the problem of large amount reflux of the crude oil and liquids. The device mainly comprise a shell, a valve seat and an air control valve; a valve seat is arranged inside of the shell of a single-way valve; the other end of the valve seat is a inclined angle namely a sealing plane of the single-way valve; the end surface of the control valve is also made into a corresponding inclined angle, which matches to the sealing plane of the valve seat; the valve body of the control valve is cylindrical, which is distributed with more than two permeable body grooves and is provided with a spring. The product has advantages of less energy consumption, high circulation amount, flexible control, simple structure, lightweight and easy installation.
Description
One, technical field:
The utility model belongs to engineering goods, is mainly used in crude oil or other liquid feed control device.
Two, technical background:
In some occasion, the unidirectional mobile conveying under a certain pressure state to crude oil or other liquid, one-way valve is exactly a control gear of realizing this function.Especially petroleum industry system, in the crude oil production process, some is local because social security is not good enough, the lawless person is often taken place steal and cut the well head petroleum pipeline, and not only the oil of oil well leaks, and the crude oil of other oil well also can backflow in a large number in the oil gathering station.For reducing the loss of this class, be badly in need of a kind of simple in structure and one-way valve of being convenient to install of development.
Three, summary of the invention:
The purpose of this utility model is to improve to make a kind of air gate type one-way valve.Solve crude oil or other liquid problem of backflowing in a large number under specific circumstances.It mainly is made up of housing, valve seat and valve control valve, its concrete structure like this: a valve seat is installed in this single current valve housing, and an end face of this valve seat is made as rake angle, is the sealing surface of one-way valve, is again the pod apertures of this valve.The end face of control valve also is made as corresponding draft angle, and matching with sealing surface of seat cooperates, and control valve body is cylindric, and the substantially horizontal above saturating body groove in two roads that distributes therebetween is so that the fluid passage when opening as valve body.In the control valve valve body spring is housed, spring one end is fixed on the valve seat end, and the other end is fixed on control valve valve body tail end.These one-way valve housing two ends are shaped on screw thread, so that be installed in flow process place in the station.
The beneficial effects of the utility model are that energy consumption is little, and discharge value is big, and control flexibly, and is simple in structure, in light weight, are convenient to install.
Four, description of drawings:
As figure is the utility model structural representation.
Among the figure 1, housing, 2, valve seat, 3, sealing surface of seat, 4, the air gate type control valve, 5, spring, 6, control valve valve body skeleton, 7, the saturating body groove of control valve valve body level, 8, air gate type control valve sealing surface, 9, housing end face screw thread, 10, control valve valve body tail end,
Five, mode of execution:
As seen from the figure, valve seat 2 and air gate type control valve 4 are installed in the housing 1.Make draft angle at valve seat 2 end faces, this inclined-plane is the sealing surface 3 of one-way valve, is again the pod apertures of this valve.The end face of air gate type control valve 4 correspondingly is made as draft angle, and this inclined-plane is that sealing surface 8 matches with the sealing surface 3 of valve seat 2.Air gate type control valve 4 is made of with spring 5 the saturating body groove 7 that valve body skeleton 6, valve body level are shaped on more than two roads, and spring 5 is installed in the control valve valve body inner bore; The valve body of control valve 4 is a cylindrical-shaped structure, and it is shaped on the above saturating body groove 7 in two roads is fluid passages when opening as valve body; Be fixed on valve one end at spring 5 one ends, the other end is fixed on control valve valve body tail end 10.Housing 1 two ends are shaped on screw thread 9.So that be installed in flow process place in the station.During use, when oil well ordinary production production fluid surpassed setting pressure, the air gate type control valve 4 in the housing 1 was open, and flows through the saturating body groove 7 of the level of production fluid in valve seat 2 holes.When the oil well petroleum pipeline is cut off, destroys or other accident takes place, production fluid leaks, at this moment the pipeline internal pressure is lower than setting pressure, and the control valve 4 in the housing 1 makes the sealing surface 8 of control valve be pressed on sealing surface of seat 3 under the effect of spring 5, thereby cuts off the path that the crude oil in the oil gathering station leaks.Realize the function of this air gate type one-way valve.
