Description

Technical Field:

[0001] The utility model belongs to the technical field of valves, and particularly refers to a temperature control valve. Background Art:

[0002] Ball valves and temperature control valves are usually used in air-conditioning pipelines to regulate the medium flow rate.

[0003] The Chinese utility model patent (publication number CN219472793U, application date Mar. 13, 2023, publication date Aug. 4, 2023) discloses an air-conditioning temperature control ball valve, which includes a valve stem and a valve body. The valve body has a water inlet hole and a water outlet hole. It is characterized in that the axes of the water inlet hole and the water outlet hole are parallel to each other, and the water outlet hole is arranged below the water inlet hole. A water passing hole penetrating through to the water outlet hole is opened at the top of the valve body, and the water inlet hole is communicated with the water passing hole. A ball core is arranged in the water inlet hole of the valve body, the inner end of the valve stem is connected with the ball core, the outer end of the valve stem extends out of the side part of the valve body and is fixedly connected with a handle. A mounting seat is threadedly connected to the orifice of the water passing hole of the valve body. A valve cap is threadedly connected to the top end of the mounting seat. A straight rod-shaped lifting rod axially penetrates through the mounting seat. A sealing gasket is embedded at the inner end of the lifting rod protruding out of the mounting seat. The inner wall of the water passing hole has a valve seat for the sealing gasket to abut and seal. The outer end of the lifting rod extends out of the valve cap. A spring is sleeved on the lifting rod between the mounting seat and the valve cap. A gasket and a first sealing ring are also sleeved on the lifting rod below the spring. The mounting seat has a stepped groove for accommodating the first sealing ring. The upper end of the spring acts on the lifting rod to keep the lifting rod in a trend of upward movement, and the lower end of the spring abuts against the gasket to keep the gasket in a trend of extruding the sealing ring.

[0004] The disadvantage of the above air-conditioning temperature control ball valve is that the space at the orifice of the water passing hole is small. When the water flow is large, it impacts the wall of the water passing hole, generating a large amount of noise. Summary of the Invention:

[0027] The following further describes the present utility model with specific embodiments. Refer to Figure 1 —4:

[0028] A temperature control valve includes a valve body 1 and a lifting rod 2. The valve body 1 has a water inlet channel 3 and a water outlet channel 4. A hollow mounting column 5 is provided at the top of the valve body 1. A mounting seat 6 is provided on the mounting column 5. The mounting seat 6 includes a mounting part 61 sleeved outside the mounting column 5 and an assembly part 62 provided at the top of the mounting part 61. The lifting rod 2 is slidably arranged in the assembly part 62, and the lower end of the lifting rod 2 extends out of the assembly part 62 to connect a sealing gasket 7. A water passing cavity 8 is formed between the mounting part 61 and the mounting column 5. The valve body 1 is provided with a water inlet hole 9 and a water outlet hole 10. The water inlet hole 9 communicates the water inlet channel 3 and the water passing cavity 8, and the water outlet hole 10 communicates the water outlet channel 4 and the water passing cavity 8.

[0029] As Figures 1-4 shown, the mounting part 61 of the present utility model is sleeved outside the mounting column 5, effectively utilizing the internal space of the mounting column 5. The space of the water passing cavity 8 is large and the noise is small.

[0030] Furthermore, the mounting part 61 and the assembly part 62 are of an integral structure.

[0031] Structure of the installation part 61: The installation part 61 includes an installation sleeve 611 sleeved outside the installation column 5 and a hollow frustum 612 arranged above the installation sleeve 611. The diameter of the hollow frustum 612 gradually decreases from bottom to top, effectively expanding the space of the water passage 8 and guiding the water flow at the same time, with low noise.

[0032] Installation structure of the installation sleeve 611: The installation sleeve 611 is threadedly connected to the installation column 5.

[0033] Furthermore, a cavity 11 with an open lower end is provided inside the installation part 61. A plug cap 12 for blocking the lower end opening of the cavity 11 is provided on the installation part 61. A spring 13 sleeved on the lifting rod 2 is provided inside the cavity 11. The upper end of the lifting rod 2 extends out of the installation part 61, and the lower end extends out of the plug cap 12 to connect the sealing gasket 7. A circular groove 14 is concavely formed at the bottom of the installation part 61. The outer wall of the circular groove 14 is connected to the hollow frustum 612, and the inner wall is connected to the plug cap 12. The setting of the circular groove 14 further expands the space of the water passage, thereby reducing noise.

[0034] Installation structure of the plug cap 12: The inner wall of the circular groove 14 is sleeved outside the plug cap 12 and is threadedly connected to the plug cap 12, further increasing the space of the water passage 8.

[0035] Furthermore, both the water inlet passage 3 and the water outlet passage 4 are circular passages and are coaxially arranged. The water inlet passage 3 and the water outlet passage 4 are separated by a partition plate 15. The water inlet hole 9 and the water outlet hole 10 are both arranged at the top of the valve body 1. The water inlet hole 9 is coaxially arranged with the installation column 5 and the lifting rod 2. The lifting rod 2 moves up and down, driving the sealing gasket 2 to move up and down, thereby blocking and opening the water inlet hole 9. The coaxial arrangement of the water inlet passage 3 and the water outlet passage 4 facilitates wrapping the protection cotton outside the present utility model.

[0036] Preferably, both the water inlet passage 3 and the water outlet passage 4 are circular passages and have equal diameters. The installation column 5 is a hollow cylindrical shape, and the inner diameter of the installation column 5 is 1.5 times - 2.5 times the diameter of the water inlet passage 3. The large inner diameter of the installation column 5 results in a large space for the water passage 8, effectively reducing the noise of the water flow and the resistance of the water flow. In this embodiment, the inner diameter of the installation column 5 is 39 mm, the diameter of the water inlet passage 3 is 21 mm, and the inner diameter of the installation column 5 is 1.857 times the diameter of the water inlet passage 3. The large diameters of the water inlet passage 3 and the water outlet passage 4 result in a large flow rate.

[0037] Furthermore, a valve ball 16 is provided inside the water outlet passage 4. One end of the valve ball 16 is connected to one end of a valve rod 17, and the other end of the valve rod 17 extends out of the valve body 1 to connect to a handle 18. The ball valve and the temperature control valve of the present utility model are combined into one valve body 1, eliminating the need for separate installation of the ball valve and the temperature control valve, facilitating installation, reducing the installation cost, and effectively reducing the leakage points.

[0038] In order to avoid rotating the pipeline and the valve body 1 when connecting the pipeline, as Figure 2 shown, a connecting nut 19 is axially limited at the end of the water inlet passage 3 of the valve body 1, and an internal thread 20 for connecting the pipeline is provided in the connecting nut 19. Connecting the pipeline by rotating the connecting nut 19 is convenient for connection.

[0039] The above embodiments are only one of the preferred embodiments of the present invention, and do not limit the scope of implementation of the present invention. Therefore, all equivalent changes made according to the shape, structure and principle of the present invention should be covered within the protection scope of the present invention.
