The top of the top rotating shaft extends out of the top of the valve body and is provided with a handle through a connecting rod, the left side and the right side of the interior of the spherical rotating core are provided with liquid inlets and liquid outlets which are communicated with each other, and the spherical rotating core is communicated with pipelines in the connecting pipes on the two sides through the liquid inlets and the liquid outlets. The one-way valve core controls the fluid to flow in one way, and the spherical rotating core can rotate in the valve body, so that the one-way flowing direction of the fluid is adjusted. The one-way valve is reasonable in design, on the premise that one-way flowing of fluid is controlled, after the one-way valve is connected and installed with a fixed pipeline, the allowed flowing direction of the one-way valve can still be changed through the handle, and the valve body does not need to be replaced even if the direction of the pipeline needs to be changed in the later period.

Description

A steerable one-way valve for hydraulic engineering Technical Field

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

[0002] A check valve is an automatic valve that allows fluid to flow in only one direction, and it is widely used in petroleum, chemical, water conservancy, and hydraulic systems. Its core principle relies on the fluid pressure difference to drive a valve disc (such as a ball, flap, or lift structure) to open and close: the valve disc opens when the forward pressure is greater than the reverse pressure, and closes otherwise. Traditional designs include swing, lift, and ball types, which have advantages such as simple structure, fast response, and good sealing. However, the permissible flow direction of existing check valves is limited by their physical structure during manufacturing (such as the valve seat tilt angle and spring preload direction), and cannot be dynamically adjusted according to operating conditions after installation, resulting in insufficient system flexibility. Summary of the Invention

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

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A steerable one-way valve for hydraulic engineering includes a valve body, connecting pipes, a spherical rotating core, a rotating shaft, a connecting rod, a handle, a valve core cavity, inlet and outlet ports, and a one-way valve core. Connecting pipes are integrally formed at both ends of the valve body. A spherical rotating core is installed at the center inside the valve body. Rotating shafts are installed at the top and bottom of the spherical rotating core and connected to the valve body via these shafts. The top rotating shaft extends beyond the top of the valve body and is connected to a handle via a connecting rod. Inlet and outlet ports are interconnected on both sides of the spherical rotating core and are connected to pipes inside the connecting pipes on both sides. A one-way valve core is installed inside each inlet and outlet port, controlling the unidirectional flow of fluid. The spherical rotating core can rotate within the valve body to adjust the direction of the permissible unidirectional flow of fluid.

[0006] Preferably, the steerable one-way valve for hydraulic engineering further includes a slide groove, a hemispherical valve core, a connecting rod, and a limiting rod. Slide grooves are provided at both the upper and lower ends of the inlet and outlet. A hemispherical valve core is installed on the left side of the inlet and outlet. A limiting rod is installed on the center of the right side of the hemispherical valve core via the connecting rod. The top and bottom of the limiting rod are installed in the slide groove at the corresponding end. The hemispherical valve core can move in the left area inside the inlet and outlet following the direction of fluid flow and is restricted by the limiting rod to prevent it from moving to the right side, thereby controlling the unidirectional flow of fluid.

[0007] Preferably, the outer side of the handle faces the same direction as the one-way valve core inside the spherical rotating core, allowing for easy observation when changing the one-way flow direction via the handle.

[0008] The beneficial effects of this utility model are: This utility model is reasonably designed. Under the premise of achieving unidirectional control of fluid flow, after being connected and installed with a fixed pipeline, the direction of flow allowed by the one-way valve can still be changed by the handle. Even if the pipeline needs to be reversed later, there is no need to replace the valve body. Attached Figure Description

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0014] As shown in Figures 1-3, a steerable one-way valve for hydraulic engineering includes a valve body 1, a connecting pipe 2, a spherical rotating core 3, a rotating shaft 4, a connecting rod 5, a handle 6, a valve core cavity 7, inlet and outlet ports 8, and a one-way valve core 9. The valve body 1 has connecting pipes 2 integrally formed at both ends. A spherical rotating core 3 is installed at the center inside the valve body 1. Rotating shafts 4 are installed at the top and bottom of the spherical rotating core 3 and are connected to the valve body 1 via the rotating shafts 4. The top of the rotating shaft 4 extends beyond the top of the valve body 1 and is connected to a handle 6 via the connecting rod 5. Inlet and outlet ports 8 are interconnected on both sides of the spherical rotating core 3 and are connected to the pipes inside the connecting pipes 2 on both sides. A one-way valve core 9 is installed inside each inlet and outlet port 8, controlling the unidirectional flow of fluid. The spherical rotating core 3 can rotate within the valve body 1 to adjust the direction of the unidirectional fluid flow. The directional one-way valve for hydraulic engineering also includes a slide groove 10, a hemispherical valve core 11, a connecting rod 12, and a limiting rod 13. Slide grooves 10 are provided at both the upper and lower ends of the inlet / outlet port 8. The hemispherical valve core 11 is installed on the left side of the inlet / outlet port 8, and a limiting rod 13 is installed on the right center of the hemispherical valve core 11 via the connecting rod 12. The top and bottom of the limiting rod 13 are installed within the corresponding slide groove 10. The hemispherical valve core 11 can move in the left region inside the inlet / outlet port 8 following the direction of fluid flow, and is restricted by the limiting rod 13 to prevent it from moving to the right, thus controlling the unidirectional flow of fluid. The outer side of the handle 6 faces the same direction as the one-way valve core 9 inside the spherical rotating core 3, facilitating observation when changing the unidirectional flow direction using the handle 6.

[0015] The working principle of this utility model is as follows: the valve body 1 is connected to the fixed pipeline through the connecting pipes 2 on both sides, and the one-way valve core 9 inside the valve core 1 is installed in the rotatable spherical rotating core 3. The spherical rotating core 3 can be rotated by the handle 6, thereby changing the direction of the one-way valve core 9 inside the valve body 1, thereby changing the direction of the fluid flow in one direction.

[0016] The hemispherical valve core 11 can move in the left region inside the inlet / outlet port 8 following the direction of fluid flow, and is restricted by the limiting rod 13 to prevent it from moving to the right. At this time, the fluid moves from left to right. When the fluid flow direction is reversed, the fluid drives the hemispherical valve core 11 to move to the left and closes the left side of the inlet / outlet port 8, thereby controlling the unidirectional flow of fluid.

[0017] 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.
