Description

Technical Field

[0001] This utility model relates to the field of float valve technology, specifically an automatic water replenishment valve driven without differential pressure. Background Technology

[0002] A float valve is a type of valve consisting of a crank arm and a float, used to control the liquid level. An automatic water supply valve provides simple control of the liquid level in large-area, low-height water supply and receiving containers, especially in situations where the inlet pressure is low or the supply is driven solely by the difference in liquid levels between the supply and demand sides.

[0003] The existing automatic water supply valve has a problem: when the water supply pressure is very low, the outlet chamber itself is smaller than the water pipe diameter. When the outlet chamber is narrow, the problem of low pressure on the supply side will be amplified, and the water flow rate and flow rate will drop sharply. Moreover, the liquid level on the supply side is only slightly higher than that on the receiving side. Although there is a small liquid level difference between the supply and receiving sides, the water flow cannot replenish the receiving end in time, and cannot meet the continuous water demand of the receiving end.

[0004] Therefore, this utility model proposes an automatic water supply valve driven without differential pressure to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an automatic water supply valve that is not driven by differential pressure, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An automatic water replenishment valve driven without differential pressure, comprising a float ball, a liquid level adjustment latch on one side of the float ball, a blind plate on one side of the liquid level adjustment latch, a rotating block at the bottom of the blind plate, a connecting pipe on one side of the rotating block, and a fixing block at the bottom of the connecting pipe.

[0007] A connecting pipe 2 is provided on one side of the fixing block, and triangular clamps are provided on both sides of the connecting pipe 2. A water pipe is provided on the outside of the triangular clamps.

[0008] The surface of the water pipe is provided with a limiting groove.

[0009] Preferably, the fixed block has a second mounting groove on one side, and the rotating block has rotating shafts mounted on both sides, with two sets of rotating shafts fixedly mounted on both sides of the second mounting groove.

[0010] Preferably, a second connecting pipe is fixedly sleeved inside one side of the first connecting pipe, and an installation groove is opened on both sides of the second connecting pipe. A spring is fixedly installed at the bottom of the first installation groove, the top of the spring is fixedly connected to the triangular block, and the bottom of the triangular block is located inside the first installation groove.

[0011] Preferably, a receiving groove is provided on one side of the water pipe, and the size of the receiving groove is adapted to the connecting pipe.

[0012] Preferably, the receiving groove is provided with limiting grooves on both sides of the water pipe sidewall, and sliding grooves are provided on both sides of the two sets of limiting grooves. The two sets of sliding grooves penetrate the water pipe sidewall, and extrusion blocks are slidably installed in the two sets of sliding grooves.

[0013] Preferably, a pressing block is fixedly installed on one side of each of the two sets of extrusion blocks, and a second spring is provided at both ends of the pressing block near the water pipe. One end of the second spring is fixedly connected to the pressing block, and the other end of the second spring is fixedly connected to the side wall of the water pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When the connecting pipe 2 is inserted into the limiting groove, and the connecting pipe 2 is inserted until the triangular locking block contacts the water pipe, the triangular locking block is pressed back into the installation groove 1. The triangular locking block is locked into the limiting groove, and the right side wall of the connecting pipe 1 is pressed against the side wall of the water pipe, thus completing the installation. The pressing block drives the squeezing block to move in the sliding groove. At this time, the triangular locking block is pressed into the installation groove 1, and the connecting pipe 1 can be pulled out to complete the disassembly. In use, when the liquid level drops, the float ball drops. The rotating block set at the bottom of the blind plate rotates on the fixed block, which drives the blind plate to open. The liquid in the water pipe flows out directly through the connecting pipe 1 without resistance. After passing through the float ball, it gradually rises. When the float ball rises to the predetermined height, the blind plate completely blocks the outlet, which can keep the liquid level of the downstream container relatively constant, thus avoiding the problem.

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1: Please refer to Figures 1 to 6 This utility model provides a technical solution: an automatic water replenishment valve driven without differential pressure, including a float ball 1, a liquid level adjustment latch 2 on one side of the float ball 1, a blind plate 3 on one side of the liquid level adjustment latch 2, a rotating block 7 at the bottom of the blind plate 3, a connecting pipe 4 on one side of the rotating block 7, a fixing block 6 at the bottom of the connecting pipe 4; a connecting pipe 9 on one side of the fixing block 6, triangular locking blocks 10 on both sides of the connecting pipe 9, a water pipe 5 on the outside of the triangular locking blocks 10; and a limit groove 17 on the surface of the water pipe 5.

[0024] Before using this automatic water supply valve, align the connecting pipe 2 9 with the limiting groove 17 on the side wall of the water pipe 5, and insert the connecting pipe 2 9 into the limiting groove 17. When the connecting pipe 2 9 is inserted until the triangular locking block 10 contacts the water pipe 5, continue inserting. At this time, the triangular locking block 10 will be compressed and retracted into the installation groove 11. Continue inserting until the right side of the connecting pipe 2 9 contacts the lowest end of the limiting groove 17. At this time, the triangular locking block 10 is locked into the limiting groove 17, and the right side wall of the connecting pipe 2 4 is pressed against the side wall of the water pipe 5. The installation is then complete. When not in use, press the pressing block 8. The pressing block 8 drives the squeezing block 14 to move in the sliding groove 16. At this time, the spring 2 15 is compressed and retracted, and the squeezing block 14 squeezes the triangular locking block 11. When the spring 12 at the bottom of the triangular locking block 10 retracts, the triangular locking block 10 is pressed into the mounting groove 11. The connecting pipe 4 can then be pulled out to complete disassembly. During use, the float 1 moves up and down depending on the liquid level. When the liquid level drops, the float 1 descends, and the rotating block 7 at the bottom of the blind plate 3 rotates on the fixed block 6, causing the blind plate 3 to open. The liquid in the water pipe 5 flows out directly through the connecting pipe 4 without resistance, thus raising the liquid level in the downstream container. This causes the float 1 to gradually rise. As the float 1 rises, the blind plate 3 rotates, gradually closing. When the float 1 reaches the predetermined height, the blind plate 3 completely blocks the outlet. This cycle maintains a relatively constant liquid level in the downstream container.

[0025] Example 2: Based on Example 1, for ease of installation, a second mounting groove 18 is provided on one side of the fixing block 6, and rotating shafts are rotatably installed on both sides of the rotating block 7. The two sets of rotating shafts are fixedly installed on both sides of the second mounting groove 18. A second connecting pipe 9 is fixedly sleeved inside one side of the connecting pipe 4. A first mounting groove 11 is provided on both sides of the connecting pipe 9. A first spring 12 is fixedly installed at the bottom of the first mounting groove 11. The top of the first spring 12 is fixedly connected to the triangular locking block 10. The bottom of the triangular locking block 10 is located inside the first mounting groove 11. A receiving groove 13 is provided on one side of the water pipe 5. The size of the receiving groove 13 is adapted to the second connecting pipe 9.

[0026] Before use, align the connecting pipe 2 9 with the limiting groove 17 on the side wall of the water pipe 5, and insert the connecting pipe 2 9 into the limiting groove 17. When the connecting pipe 2 9 is inserted until the triangular locking block 10 contacts the water pipe 5, continue to insert it. At this time, the triangular locking block 10 will be pressed back into the installation groove 11. Continue to insert it until the right side of the connecting pipe 2 9 contacts the lowest end of the limiting groove 17. At this time, the triangular locking block 10 is locked into the limiting groove 17, and the right side wall of the connecting pipe 1 4 is pressed against the side wall of the water pipe 5. The installation is then complete.

[0027] Example 3: Based on Example 2, in order to facilitate disassembly, limiting grooves 17 are opened on both sides of the receiving groove 13 on the side wall of the water pipe 5. Sliding grooves 16 are opened on both sides of the two sets of limiting grooves 17. The two sets of sliding grooves 16 pass through the side wall of the water pipe 5. Pressing blocks 14 are slidably installed in the two sets of sliding grooves 16. Pressing blocks 8 are fixedly installed on one side of each of the two sets of pressing blocks 14. Springs 15 are provided at both ends of the pressing blocks 8 near the water pipe 5. One end of the springs 15 is fixedly connected to the pressing blocks 8, and the other end of the springs 15 is fixedly connected to the side wall of the water pipe 5.

[0028] When disassembly is required, press the pressing block 8. The pressing block 8 drives the squeezing block 14 to move in the slide groove 16. At this time, the second spring 15 is compressed and contracts. The squeezing block 14 squeezes the triangular locking block 10. The first spring 12 at the bottom of the triangular locking block 10 contracts. At this time, the triangular locking block 10 is pressed into the first mounting groove 11. The connecting pipe 4 can be pulled out to complete the disassembly.

[0029] In actual use, insert connecting pipe 2 9 into the limiting groove 17. When connecting pipe 2 9 is inserted until the triangular locking block 10 contacts the water pipe 5, the triangular locking block 10 is pressed back into the installation groove 11 and locked into the limiting groove 17. The right side wall of connecting pipe 1 4 is pressed against the side wall of the water pipe 5, thus completing the installation. Pressing block 8 drives squeezing block 14 to move in the sliding groove 16. At this time, the triangular locking block 10 is pressed into the installation groove 11. Pulling connecting pipe 1 4 outward completes the disassembly. During use, when the liquid level drops, float 1 descends. The rotating block 7 at the bottom of the blind plate 3 rotates on the fixed block 6, causing the blind plate 3 to open. The liquid in the water pipe 5 flows out directly through connecting pipe 1 4 without resistance, and gradually rises through float 1. When float 1 rises to the predetermined height, the blind plate 3 completely blocks the outlet. This cycle continues, maintaining a relatively constant liquid level in the downstream container.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
