Abstract
Description
Technical Field
[0001] This utility model relates to the field of reversing valves, and in particular to a rainwater and sewage diversion reversing valve. Background Technology
[0002] A directional valve is a valve used to control the direction of liquid flow. By manually rotating the valve core, the direction of liquid flow can be controlled, so it is widely used in various liquid transportation applications.
[0003] However, in applications where rainwater and sewage are separated, rainwater is transported in a fixed direction. When the rainwater flow is too large, the valve switching part lacks a positioning structure and is not secure enough. The valve core is prone to loosening. Furthermore, the switching is done manually, which is not reliable. If manual operation is missed, the valve cannot adjust the switching operation according to the water flow, increasing the safety risks of using the valve. Therefore, existing directional valves are not suitable for rainwater and sewage separation applications. Utility Model Content
[0004] The main objective of this invention is to provide a rainwater and sewage diversion valve that can effectively solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A rainwater and sewage diversion valve includes a mounting plate, a valve seat, an inlet port, and an outlet port. The valve seat is welded to the upper end of the mounting plate. The inlet port is integrally formed on the upper end of the valve seat. Two outlet ports are integrally formed on both sides of the valve seat. A connecting nut is threaded onto the lower end of the mounting plate. A valve stem is movably mounted on the lower end of the connecting nut. A connecting base is fixedly mounted on the lower end of the valve stem. A valve core is fixedly mounted inside the valve seat at the upper end of the valve stem. A socket plate is fixedly mounted on the outer side of the connecting base. A jacking seat is fixedly mounted on the upper end of the connecting base. A jacking screw is threaded onto the upper end of the jacking seat. A positioning sleeve is fixedly mounted on the outer side of the valve stem at the lower end of the connecting nut. A torsion spring is fixedly mounted on the outer side of the positioning sleeve. A rod insertion structure is provided inside the inlet port.
[0007] As a further embodiment of this utility model, the inlet and outlet ports are connected to the interior of the valve seat, and the valve stem passes through the connecting nut and the mounting plate.
[0008] As a further embodiment of this utility model, the jacking seat is located on one side of the positioning sleeve, and the lower end of the torsion spring rests on the outside of the jacking screw.
[0009] As a further embodiment of this utility model, an operating handle is welded to the outer side of the connecting base on one side of the socket plate, and the connecting base drives the valve core to rotate through the valve stem.
[0010] As a further embodiment of this utility model, the insertion rod structure includes a positioning insertion rod, a pressing plate, a jacking ring, and a sealing sleeve. The positioning insertion rod movably passes through the mounting plate and is located in front of the valve seat. The pressing plate is movably installed inside the front of the inlet pipe. The jacking ring is fixedly installed at the front end of the pressing plate. The sealing sleeve is fixedly installed on the outside of the inlet pipe and fits against the outer wall of the inlet pipe.
[0011] As a further embodiment of this utility model, the pressing plate penetrates the pipe wall of the inlet, the jacking ring is sleeved on the outside of the positioning rod, and the lower end of the positioning rod is inserted into the socket plate for connection.
[0012] Compared with the prior art, this utility model has the following advantages: When the reversing valve rotates to one side, it drives the torsion spring to store force, and then inserts the positioning rod into the socket plate to position the connecting base, thereby achieving a firm positioning of the valve core and preventing the valve core from loosening. When the water flow pressure in the inlet is too high, the water flow impacts the pressure plate downwards and moves it up, which in turn drives the jacking ring to lift the positioning rod and separate it from the socket plate. Therefore, the torsion spring exerts force, which drives the connecting base to rotate to one side through the jacking screw and jacking seat, and finally drives the valve core to rotate, switching the diversion position of rainwater from the outlet pipe. This achieves automatic channel switching when the water flow is too high, eliminating the trouble of manual switching and making it more suitable for rainwater and sewage diversion.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0019] like Figures 1-4 As shown, a rainwater and sewage diversion valve is provided; please refer to it carefully. Figures 1-4 The system includes a mounting plate 1, a valve seat 2, an inlet port 3, and an outlet port 4. The valve seat 2 is welded to the upper end of the mounting plate 1. The inlet port 3 is integrally formed on the upper end of the valve seat 2. The two outlet ports 4 are integrally formed on both sides of the valve seat 2. A connecting nut 5 is threaded onto the lower end of the mounting plate 1. A valve stem 6 is movably mounted on the lower end of the connecting nut 5. A connecting base 7 is fixedly mounted on the lower end of the valve stem 6. A valve core 9 is fixedly mounted inside the valve seat 2 at the upper end of the valve stem 6. A socket plate 14 is fixedly mounted on the outer side of the connecting base 7. A push seat 12 is fixedly mounted on the upper end of the connecting base 7. A push screw 13 is threaded onto the upper end of the push seat 12. A positioning sleeve 10 is fixedly mounted on the lower end of the connecting nut 5 outside the valve stem 6. A torsion spring 11 is fixedly mounted on the outer side of the positioning sleeve 10. A rod insertion structure 15 is provided inside the inlet port 3.
[0020] Please refer to this carefully. Figure 3 The inlet port 3 and outlet port 4 are connected to the inside of the valve seat 2, and the valve stem 6 passes through the connecting nut 5 and the mounting plate 1.
[0021] Specifically, rainwater enters through inlet 3, then flows through the hole on valve core 9 and out through the corresponding outlet 4 to achieve rainwater diversion.
[0022] Please refer to this carefully. Figures 1-3 The actuating seat 12 is located on one side of the positioning sleeve 10, and the lower end of the torsion spring 11 rests on the outside of the actuating screw 13. The torsion spring 11 actuates the connecting base 7 to rotate through the actuating screw 13.
[0023] Please refer to this carefully. Figures 1-3 An operating handle 8 is welded to the outer side of the connecting base 7 on one side of the socket plate 14. The connecting base 7 drives the valve core 9 to rotate through the valve stem 6.
[0024] Specifically, the operating handle 8 is used to rotate the connecting base 7 and the valve stem 6, thereby rotating the valve core 9 to control the diversion channel in the valve seat 2 and switch different discharge ports 4 to allow rainwater to flow out.
[0025] Please refer to this carefully. Figure 1 , Figure 2 and Figure 4The insertion rod structure 15 includes a positioning insertion rod 16, a pressing plate 17, a jacking ring 18, and a sealing sleeve 19. The positioning insertion rod 16 movably passes through the mounting plate 1 and is located in front of the valve seat 2. The pressing plate 17 is movably installed inside the front of the inlet port 3. The jacking ring 18 is fixedly installed at the front end of the pressing plate 17. The sealing sleeve 19 is fixedly installed on the outside of the inlet port 3 and fits against the outer wall of the inlet port 3.
[0026] Please refer to this carefully. Figure 1 , Figure 2 and Figure 4 The pressing plate 17 penetrates the pipe wall of the inlet 3, the pushing ring 18 is sleeved on the outside of the positioning rod 16, and the lower end of the positioning rod 16 is inserted into the socket plate 14 for mating connection.
[0027] Specifically, when the connecting base 7 rotates from one side to the other, the torsion spring 11 is also rotated through the jacking seat 12 and the jacking screw 13, causing the torsion spring 11 to store force. Then, the positioning rod 16 is inserted into the socket plate 14 to position the connecting base 7. Therefore, when the water pressure entering the inlet pipe 3 is too high, the water flow impacts the pressure plate 17 downward, causing the rear end of the pressure plate 17 to move downward and the front end of the pressure plate 17 to tilt upward, thereby driving the jacking ring 18 to lift the positioning rod 16. After the positioning rod 16 is lifted, it disconnects from the socket plate 14. Therefore, the torsion spring 11 exerts force, driving the connecting base 7 to rotate to one side through the jacking screw 13 and the jacking seat 12, and finally driving the valve core 9 to rotate, switching the diversion position of rainwater from the outlet pipe 4.
[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
