Description

Technical Field

[0001] This utility model belongs to the field of valves, specifically, it relates to a control valve for water conservancy and hydropower with good sealing effect. Background Technology

[0002] Control valves for water conservancy and hydropower play a crucial role in water conservancy and hydropower facilities. These valves are mainly used to control parameters such as water flow, water pressure, and temperature, thereby achieving precise regulation of facilities such as sluice gates, water pumps, reservoirs, and water pipes in the fields of water conservancy, hydropower, water supply and drainage, and heating, ventilation and air conditioning. Their working principle is based on advanced control technology, which can achieve precise control of parameters such as water flow and water pressure.

[0003] Chinese utility model patent CN213236433U discloses a control valve for water conservancy and hydropower with good sealing effect, including a valve body assembly and a connecting joint. The connecting joint is connected to both sides of the valve body assembly. The connecting joint is provided with fasteners and connecting pipes. The connecting pipes are inserted into the corresponding connecting joints. The fasteners are sleeved on the outer wall of the connecting pipes and inserted into the interior of the connecting joints. Although the above-mentioned control valve prevents the fasteners from rotating after connection through the cooperation of the connecting column and clamp, thus avoiding loosening, in actual use, when it is necessary to disassemble the connecting joints and connecting pipes, the remaining water in the valve body, connecting joints and connecting pipes can easily leak out through the outlet pipe, resulting in water waste.

[0004] In view of this, this utility model is proposed. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a control valve for water conservancy and hydropower with good sealing effect, thus solving the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A control valve for water conservancy and hydropower with good sealing effect includes: a valve body assembly, with connecting joints connected to both sides of the valve body assembly, connecting pipes respectively provided at both ends of the connecting joints, and fasteners provided between the connecting joints and the connecting pipes;

[0008] The connecting joint is provided with a first elastic sealing element, and the connecting pipe is provided with a second elastic sealing element. The second elastic sealing element is provided with a compression rod corresponding to the first elastic sealing element.

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] Please see Figure 1-3 As shown, this embodiment provides a control valve for water conservancy and hydropower with good sealing effect, including: valve body assembly 1, connecting joints 2 connected to both sides of valve body assembly 1, connecting pipes 3 respectively provided at both ends of connecting joints 2, and fasteners 6 provided between connecting joints 2 and connecting pipes 3;

[0026] The connecting joint 2 is provided with a first elastic sealing element 7, and the connecting pipe 3 is provided with a second elastic sealing element 8. The second elastic sealing element 8 is provided with a compression rod 9 corresponding to the first elastic sealing element 7.

[0027] By providing a first elastic sealing element 7 within the connecting joint 2, after the connecting pipe 3 is disassembled from the connecting joint 2 via the connecting member 6, the squeezing rod 9 releases the squeezing of the first elastic sealing element 7, and the first elastic sealing element 7 automatically seals the connecting joint 2, reducing the waste caused by the leakage of residual water in the valve body assembly 1 and the connecting joint 2. By providing a second elastic sealing element 8 within the connecting pipe 3, after the connecting pipe 3 is disassembled from the connecting joint 2, the second elastic sealing element 8 automatically seals the connecting pipe 3, thereby reducing the waste caused by the leakage of water in the connecting pipe 3.

[0028] like Figure 1 As shown, the fastener 6 in this embodiment includes an external thread 601 disposed on the outside of the connecting joint 2 and an internal thread 602 disposed on the inside of the connecting pipe 3 and meshing with the external thread 601.

[0029] Among them, rotating the connecting pipe 3, the connecting pipe 3 can be disassembled and assembled with the connecting joint 2 by the engagement of the external thread 601 and the internal thread 602, thereby improving the sealing performance between the connecting pipe 3 and the connecting joint 2.

[0030] like Figure 2-3 As shown, the first elastic sealing member 7 in this embodiment includes a first blocking ring 701 disposed inside the connecting joint 2, a first sealing head 702 located inside the connecting joint 2 and abutting against the first blocking ring 701, a first fixing plate 703 disposed at the pipe opening of the connecting joint 2, and a first tension spring 704 disposed between the first fixing plate 703 and the first sealing head 702; the second elastic sealing member 8 includes a second blocking ring 801 disposed inside the connecting pipe 3, a second sealing head 802 located inside the connecting pipe 3 and abutting against the second blocking ring 801, a second fixing plate 803 disposed inside the connecting pipe 3, and a second tension spring 804 disposed between the second fixing plate 803 and the second blocking ring 801; a pressing rod 9 is disposed on one side of the second fixing plate 803; both the first sealing head 702 and the second sealing head 802 have chamfers on one side that abut against the first blocking ring 701 and the second blocking ring 801; a through hole 10 corresponding to the pressing rod 9 is opened on one side of the first fixing plate 703.

[0031] When the connecting pipe 3 is installed with the connecting joint 2, the squeezing rod 9 squeezes the first sealing head 702 away from the first blocking ring 701 through the through hole 10 to remove the seal on the connecting joint 2, so that the water pump body 2 can draw water from the inlet pipe 3 to the connecting joint 2 and enter the connecting pipe 3. The water in the connecting pipe 3 squeezes the second sealing head 802 away from the second blocking ring 801, so that the second sealing head 802 can remove the seal on the connecting pipe 3.

[0032] After the connecting pipe 3 is disassembled from the connecting joint 2, the squeezing rod 9 does not squeeze the first sealing head 702. The first sealing head 702 is reset by the elastic force of the first tension spring 704 and abuts against the first blocking ring 701 through the chamfer. The first sealing head 702 can seal the connecting joint 2. The second sealing head 802 in the connecting pipe 3 is reset by the elastic force of the second tension spring 804. The second sealing head 802 abuts against the second sealing head 802 through the chamfer. The second sealing head 802 can seal the connecting pipe 3, thereby reducing the leakage of residual water in the valve body assembly 1, connecting joint 2 and connecting pipe 3, which would otherwise lead to waste.

Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model.
