Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering, and in particular to a steerable one-way valve body for water conservancy engineering. Background Technology

[0002] The limitation of traditional check valves lies in their fixed fluid flow direction. Once installed, the permitted flow direction cannot be changed. When the pipeline system layout is changed or the process requires reverse water flow, complex valve replacement and pipeline modification are necessary, which not only increases construction difficulty and time costs but also leads to a waste of resources. Utility Model Content

[0003] The purpose of this invention is to provide a steerable one-way valve body for water conservancy projects, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A steerable one-way valve body for hydraulic engineering includes a valve body, connecting pipes, a rotating ball valve, fluid inlet and outlet, an arc-shaped connecting cavity, an extension rod, a valve plate, a connecting rod, and a spring. Connecting pipes are welded to both ends of the valve body. A rotating ball valve is installed at the center of the valve body's interior. Fluid inlet and outlet are located on both sides of the rotating ball valve. An arc-shaped connecting cavity is located inside the rotating ball valve. An extension rod is integrally formed at the top center of the arc-shaped connecting cavity. A valve plate matching the fluid inlet and outlet is installed on the left side of the arc-shaped connecting cavity. A connecting rod is installed at the center of the right side of the valve plate, and the connecting rod is installed inside the extension rod and can move left and right on the extension rod. A spring is installed on the connecting rod, located between the valve plate and the extension rod, thereby closing the valve plate. When fluid pressure passes through the valve plate from the opposite direction, it forces the spring to open.

[0005] Preferably, the steerable one-way valve body of the water conservancy project further includes a nut, a locking screw, and a rotating handle. A nut is installed at the center of the top of the valve body, a locking screw is installed inside the nut, a rotating handle is installed at the top of the locking screw, and the bottom of the locking screw passes through the rotating ball valve and the interior of the extension rod. It can be fixed by continuously rotating downwards to secure the connecting rod that extends into the extension rod.

[0006] Preferably, the steerable one-way valve body of the water conservancy project also includes a rotating shaft and a steering handle. The bottom center of the valve body is connected to a rotating ball valve through the rotating shaft. A steering handle is installed at the bottom of the rotating shaft, and the rotating ball valve can be flipped inside the valve body through the steering handle to change the direction in which the one-way valve allows fluid to pass.

[0007] The beneficial effects of this utility model are: This utility model is reasonably designed and can control the rotation of the built-in valve body and adjust the direction in which the fluid is allowed to pass through the valve body. When the pipeline system layout is changed or the process flow requires reverse transportation, there is no need to replace or modify the pipeline, which reduces the difficulty of construction and time cost.

[0010] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-2As shown, a steerable one-way valve body for hydraulic engineering includes a valve body 1, a connecting pipe 2, a rotating ball valve 3, fluid inlet and outlet 4, an arc-shaped connecting cavity 5, an extension rod 6, a valve plate 7, a connecting rod 8, and a spring 9. The valve body 1 has connecting pipes 2 welded to both its left and right ends. A rotating ball valve 3 is installed at the center inside the valve body 1. Fluid inlet and outlet 4 are provided on both the left and right sides of the rotating ball valve 3. An arc-shaped connecting cavity 5 is provided inside the rotating ball valve 3. An extension rod 6 is integrally formed at the top center of the arc-shaped connecting cavity 5 inside the rotating ball valve 3. A valve plate 7 matching the fluid inlet and outlet 4 is installed on the left side of the arc-shaped connecting cavity 5. A connecting rod 8 is installed at the center of the right side of the valve plate 7, and the connecting rod 8 is installed inside the extension rod 6 and can move left and right on the extension rod 6. A spring 9 is installed on the connecting rod 8, and the spring 9 is located between the valve plate 7 and the extension rod 6, thereby closing the valve plate 7. When fluid pressure passes through the valve plate 7 from the opposite direction, it forces the spring 9 to open. The steerable one-way valve body of the hydraulic engineering project also includes a nut 10, a locking screw 11, and a rotating handle 12. The nut 10 is installed at the top center of the valve body 1, and the locking screw 11 is installed inside the nut 10. The rotating handle 12 is installed at the top of the locking screw 11. The bottom of the locking screw 11 passes through the rotating ball valve 3 and the extension rod 6, and can be fixed by continuously rotating downwards to secure the connecting rod 8 that extends into the extension rod 6. The steerable one-way valve body of the hydraulic engineering project also includes a rotating shaft 13 and a steering handle 14. The bottom center of the valve body 1 is connected to the rotating ball valve 3 via the rotating shaft 13, and the steering handle 14 is installed at the bottom of the rotating shaft 13. The rotating ball valve 3 can be flipped inside the valve body 1 by the steering handle 14, changing the direction in which the one-way valve allows fluid to pass.

[0011] The working principle of this utility model is as follows: The one-way valve is pressed by the fluid pressure to move the valve plate 7 in the opposite direction, and flows to the other end through the arc-shaped connecting cavity 5. The bottom of the locking screw 11 can be controlled by rotating the handle 12 to pass through the rotating ball valve 3 and the extension rod 6. By continuously rotating downward, the connecting rod 8 that extends into the extension rod 6 is fixed, thereby closing the movement space of the valve plate 7 and directly closing the valve body. When the pipeline system layout is changed or the process flow requires reverse transportation, the rotating handle 14 is rotated to drive the rotating ball valve 13 to flip inside the valve body 1 through the rotating shaft 13, changing the direction in which the one-way valve allows the fluid to pass.

[0012] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary in all respects, and thus equivalent variations within the scope of this invention are included within its scope.
