Description

Technical Field

[0001] This invention relates to the field of valves, and in particular to an automatic shut-off valve specifically designed for solar water heaters. Background Technology

[0002] Valves are control components in fluid transport systems. Currently, valves are mainly divided into manually controlled mechanical valves and automatically controlled solenoid valves. When a water storage tank is full, a mechanical valve requires manual closing, which is cumbersome and cannot close automatically. Solenoid valves, on the other hand, are more expensive and require an external power source, rendering them unusable when power is off. Summary of the Invention

[0003] The technical problem this invention aims to solve is: to address the technical problems described in the background art, this invention provides an automatic shut-off valve specifically for solar water heaters. Water from the storage tank is fed into a magnetic lifting mechanism via an overflow pipe, thereby pushing magnet two upwards. Magnet two, utilizing the principle of repulsion between like poles of two magnets, pushes magnet one upwards, which in turn pushes out a sphere, blocking the flow channel. This application enables automatic valve closure without external power.

[0004] The technical solution adopted by this invention to solve its technical problem is:

[0005] An automatic shut-off valve for solar water heaters includes a valve base, a flow channel, an inlet pipe, an outlet pipe, a magnet (first), an overflow pipe, a ball, a valve core guide tube, a magnet lifting mechanism, and a magnet (second). The valve base has a flow channel, with an inlet pipe and an outlet pipe connected to its two openings respectively. One end of the valve core guide tube is connected to the valve base and communicates with the flow channel. A magnet (first) is located inside the valve core guide tube. The ball is placed inside the valve base. A magnet (second) is located between the magnet lifting mechanism and the valve base, with magnet (first) positioned above magnet (second). The outlet pipe is connected to a water storage tank, and an overflow pipe is connected to the water storage tank. The opposite ends of magnet (first) and magnet (second) are of the same level.

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0026] Combined with appendix Figure 1 and attached Figure 6 As shown, an automatic shut-off valve for solar water heaters includes a valve base 1, a flow channel 2, an inlet pipe 3, an outlet pipe 4, a magnet 5, an overflow pipe 6, a ball 7, a valve core guide tube 8, a magnet lifting mechanism 9, and a magnet 10. The valve base 1 has a flow channel 2, and the inlet pipe 3 and outlet pipe 4 are respectively connected to the two openings of the flow channel 2. One end of the valve core guide tube 8 is connected to the valve base 1 and communicates with the flow channel 2. The valve core guide tube 8 has a magnet 5 inside it. The ball 7 is placed inside the valve base 1. The magnet 10 is located between the magnet lifting mechanism 9 and the valve base 1, with the magnet 5 located above the magnet 10. The outlet pipe 4 is connected to a water storage tank 15, and the overflow pipe 6 is connected to the water storage tank 15. The two ends of the magnet 5 and the magnet 10 are of the same level.

[0027] The magnetic lifting mechanism 9 consists of a frame 91, a rocker plate 92, a water container 93, and a third magnet 94. The rocker plate 92 is hinged to the frame 91 via a shaft 95. A third magnet 94 is provided at one end of the rocker plate 92, and the third magnet 94 is located below the second magnet 10. The other end of the rocker plate 92 is hinged to the water container 93 via a shaft 12. The two opposite ends of the third magnet 94 and the second magnet 10 have the same pole.

[0028] The bottom of the water container 93 is provided with a drain hole 16, the diameter of which is smaller than the diameter of the outlet of the overflow pipe 6.

[0029] The rocker 92 is a U-shaped board.

[0030] A chamber 13 is provided between the valve core guide tube 8 and the frame 91. The chamber 13 is located below the magnet 5, and the second magnet 10 is provided inside the chamber 13.

[0031] Chamber 13 is a vacuum chamber. The vacuum chamber can improve the heat preservation performance of the valve.

[0032] A screw 14 is threaded onto the valve body 1 to block the ball 7. The screw 14 is located inside the flow channel where the water inlet pipe 3 is located. The screw 14 will prevent the ball 7 from entering the flow channel where the water inlet pipe 3 is located.

[0033] The inner walls of the two flow passages and one valve core hole of the flow channel 2 are provided with threads. The outer walls of the inlet pipe 3, the outlet pipe 4, and the valve core guide tube 8 are provided with threads. The inlet pipe 3 and the outlet pipe 4 are respectively threaded into the two flow passages of the flow channel 2, and the valve core guide tube 8 is threaded into the valve core hole of the valve body 1.

[0034] A baffle 11 is provided in the flow channel where the water outlet pipe 4 is located, and a conical hole is provided on the baffle 11.

[0035] Magnet 1 (5), Magnet 2 (10), and Magnet 3 (94) are neodymium iron boron strong magnetic cylinders.

[0036] Combined with appendix Figure 3 and attached Figure 4 As shown, in the initial state, the end of the rocker arm 92 with the water container 93 is tilted upwards, while the end of the rocker arm 92 with the magnet 94 is tilted downwards, and the ball 7 is located inside the valve core guide tube 8. When water enters the flow channel 2 through the inlet pipe 3, it flows directly into the water storage tank 15 through the conical hole on the baffle 11 and the outlet pipe 4. The water level in the water storage tank 15 gradually rises. When the water level reaches the inlet of the overflow pipe 6, the water in the water storage tank 15 will be discharged outwards through the overflow pipe 6. The outlet of the overflow pipe 6 is located above the water container 93, so the water discharged from the overflow pipe 6 will fall into the water container 93.

[0037] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 5As shown, when the water container 93 has a certain amount of water, one end of the water container 93 of the rocker 92 will drop downwards, while the other end of the rocker 92 will rise upwards. The magnet 3 94 at the upward end of the rocker 92 will use the property of like poles repelling each other to push the magnet 2 10 upwards along the chamber 13. The rising magnet 2 10 will use the principle of like poles repelling each other to push the magnet 1 5 in the valve core guide tube 8 upwards. The magnet 1 5 will push the ball 7 out of the vertical flow channel. Finally, the ball 7 will move towards the outlet pipe 4 along the direction of water flow until the ball 7 blocks the conical hole of the stop block 11. This prevents the water from continuing to flow out of the valve base 1, thus closing the valve.

[0038] Because the diameter of the drain hole 16 is smaller than the diameter of the overflow pipe 6 outlet, the amount of water flowing into the water container 93 through the overflow pipe 6 in the same amount of time is more than the amount of water leaking out through the drain hole 16. Therefore, the water in the water container 93 will increase as the overflow pipe 6 releases water. When the water in the water container 93 reaches a certain amount, it will cause the rocker arm 92 to rotate. When the overflow pipe 6 stops releasing water, all the water in the water container 93 will leak out through the drain hole 16, causing the rocker arm 92 to rotate in the opposite direction, causing the magnet 94 to fall down again, thus reopening the valve.

[0039] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
