Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to an automatic venting type water manifold composite valve. Background Technology

[0002] Automatic air-venting manifold composite valves are core components of civil heating systems, commercial central air conditioning water systems, and industrial fluid distribution systems. They are mainly used to distribute and collect fluids and to vent air from the system.

[0003] Existing composite valves mostly use a "single control mode" for venting, which controls the opening and closing of the vent by raising and lowering the float due to changes in the water level in the system. However, this structure is prone to being stuck by fluid impurities, causing the float and connecting rod to jam, resulting in the vent being unable to open or close. Furthermore, the float is prone to aging and damage when immersed in water for a long time. Once it fails, it needs to be shut down for disassembly and repair, interrupting the system operation. Once the single control mode fails, the venting function will be paralyzed, and the system operation risk is extremely high. Therefore, we propose an automatic venting type manifold composite valve. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic venting type water manifold composite valve.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic venting type water manifold composite valve, comprising a water manifold body, a valve seat connected to one side of the top of the water manifold body, a side wing provided on the top of the valve seat, a valve body connected inside the side wing, a cavity opened at the center of the interior of the valve body, a limiting ring provided at the center of the top of the valve body, one end of a lifting rod connected to the bottom of the limiting ring, the other end of the lifting rod penetrating the top side of the valve body, and a piston connected to the other end of the lifting rod, multiple connecting rods connected around the bottom of the piston, a blocking ring connected to the bottom of the connecting rods, a convex groove opened inside the blocking ring, a U-shaped rod connected around the bottom of the blocking ring, a vertical rod connected to the middle of the outer side of the U-shaped rod, a hexagonal column connected to the top of the vertical rod, a plug plate connected to the top of the hexagonal column, the hexagonal column and the plug plate being correspondingly arranged with the convex groove, and a float ball connected to the bottom of the vertical rod.

[0006] As a further embodiment of this utility model: the top inner side of the vertical rod is provided with a through groove that is compatible with the U-shaped rod.

[0007] As a further embodiment of this utility model: an air inlet is connected to the outer side of the valve body, and one end of the air inlet extends into the interior of the cavity.

[0008] As a further embodiment of this utility model: an elastic rubber pad is connected to the inner top side of the valve seat, and a sealing ring is provided on the top of the elastic rubber pad.

[0009] As a further embodiment of this utility model: an elastic rubber pad II is connected to the inner bottom side of the valve seat, and a sealing ring II is provided on the top of the elastic rubber pad II.

[0010] As a further aspect of this invention: the diameter of the cavity is greater than the diameter of the float.

[0011] As a further embodiment of this utility model: the plurality of connecting rods are arranged in a triangular shape, and the convex groove and the plurality of connecting rods are staggered.

[0012] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0013] 1. This utility model uses the combination of a float and a vertical rod to enable the hexagonal column and the blocking plate connected to them to rise and fall synchronously. When too much gas causes the water level to drop, the float synchronously drives the hexagonal column and the blocking plate to move down, and the gas moves up through the convex groove and diffuses to other places through the air inlet. As the gas is discharged, the water level recovers, and the float drives the hexagonal column and the blocking plate to re-seal the convex groove. When manual adjustment is required, the lifting rod can be moved outward to drive the piston and the blocking ring to move up synchronously. At this time, the gas also moves up through the convex groove and diffuses to the outside, achieving the effect of switching between manual and automatic control, avoiding accidents caused by problems with a single control method.

[0014] 2. This utility model, through the cooperative arrangement of elastic rubber pad one and sealing ring one, can perform a sealing operation at the connection between the valve seat and the valve body at a high point. Due to the elasticity of elastic rubber pad one, when sealing ring one wears, elastic rubber pad one uses its elasticity to drive the sealing ring to fit tightly against the valve body, improving the sealing effect and achieving the effect of self-compensation for sealing ring wear. Elastic rubber pad two and sealing ring two work similarly to perform a sealing operation at the connection between the valve seat and the bottom of the valve body, improving the overall sealing performance.

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0022] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] Please see the appendix Figure 1 -Appendix Figure 5 This utility model discloses an automatic venting type water manifold composite valve, comprising a water manifold body 1, a valve seat 2 connected to one side of the top of the water manifold body 1, a side wing 3 provided on the top of the valve seat 2, a valve body 4 connected inside the side wing 3, a cavity 5 formed at the center of the interior of the valve body 4, a limit ring 8 provided at the center of the top of the valve body 4, one end of a lifting rod 7 connected to the bottom side of the limit ring 8, the other end of the lifting rod 7 passing through the top side of the valve body 4, and a piston 9 connected to the other end of the lifting rod 7. Multiple connecting rods 10 are connected around the bottom of piston 9. A blocking ring 11 is connected to the bottom end of the connecting rod 10. A convex groove 12 is opened inside the blocking ring 11. A U-shaped rod 17 is connected around the bottom of the blocking ring 11. A vertical rod 15 is connected to the middle of the outer side of the U-shaped rod 17. A hexagonal column 13 is connected to the top of the vertical rod 15. A blocking plate 14 is connected to the top of the hexagonal column 13. The hexagonal column 13 and the blocking plate 14 are correspondingly arranged with the convex groove 12. A float ball 18 is connected to the bottom end of the vertical rod 15.

[0024] In the first embodiment, a through groove 16 adapted to the U-shaped rod 17 is provided on the inner top side of the vertical rod 15, and an air guide port 6 is connected to the outer side of the valve body 4, with one end of the air guide port 6 extending into the interior of the cavity 5.

[0025] Specifically, the float 18 and the vertical rod 15 are designed to work together so that the hexagonal column 13 and the blocking plate 14 connected to them can rise and fall synchronously. When too much gas causes the water level to drop, the float 18 will move the hexagonal column 13 and the blocking plate 14 downwards in sync, and the gas will move upwards through the convex groove 12 and diffuse elsewhere through the air guide port 6.

[0026] In embodiment 2, an elastic rubber pad 19 is connected to the top side of the inside of the valve seat 2, and a sealing ring 20 is provided on the top of the elastic rubber pad 19. An elastic rubber pad 21 is connected to the bottom side of the inside of the valve seat 2, and a sealing ring 22 is provided on the top of the elastic rubber pad 21.

[0027] Specifically, the combination of elastic rubber pad 19 and sealing ring 20 enables sealing at the connection between valve seat 2 and valve body 4 at a high position. Due to the elasticity of elastic rubber pad 19, when sealing ring 20 wears, elastic rubber pad 19 uses its elasticity to tightly fit the sealing ring against valve body 4, improving the sealing effect and achieving self-compensation for seal wear. Similarly, elastic rubber pad 21 and sealing ring 22 seal at the connection between valve seat 2 and valve body 4 at a low position, improving overall sealing performance.

[0028] Working principle:

[0029] In use, the valve body 4 is connected to the valve seat 2. The float 18 and vertical rod 15 work together to allow the connected hexagonal column 13 and plug plate 14 to rise and fall synchronously. When excessive gas causes the water level to drop, the float 18 synchronously moves the hexagonal column 13 and plug plate 14 downwards, allowing the gas to rise through the convex groove 12 and diffuse elsewhere via the air inlet 6. As the gas is discharged, the water level recovers, and the float 18 moves the hexagonal column 13 and plug plate 14 to re-seal the convex groove 12. For manual adjustment, the lifting rod 7 can be moved outwards, causing the piston 9 and plug ring 11 to rise synchronously. At this time, the gas again rises through the convex groove 12 and diffuses to the outside, achieving the desired effect. The manual / automatic switching avoids unexpected problems caused by a single control method. The combination of elastic rubber pad 19 and sealing ring 20 seals the connection between valve seat 2 and valve body 4 at a high point. Due to the elasticity of elastic rubber pad 19, when sealing ring 20 wears, the elastic rubber pad 19 uses its elasticity to tightly press the sealing ring against valve body 4, improving the sealing effect and achieving self-compensation for seal wear. Similarly, elastic rubber pad 21 and sealing ring 22 seal the connection between valve seat 2 and valve body 4 at a low point, improving overall sealing. This completes the entire workflow.
