Description

Technical Field

[0001] The present application relates to the field of valve technology, and in particular to a drain valve. Background Art

[0002] Most of the radiator drain valves on the market are made of aluminum alloy drain valves and base screw connections (such as Figure 1 As shown in the figure, this type of drain valve must be completely unscrewed to achieve the purpose of draining water. After repeated use, the thread of the connection between the valve body and the base is seriously worn. If it lasts for a long time, there is a risk of leakage, which makes the internal pressure of the water chamber insufficient and the heat dissipation performance is greatly reduced. Summary of the invention

[0003] The present application provides a drain valve, which solves the problem that a traditional drain valve must unscrew the valve body completely to achieve the purpose of draining water, and after repeated use, the threads of the connection between the valve body and the base are severely worn, and there is a risk of leakage over a long period of time, resulting in insufficient pressure in the water chamber and greatly reduced heat dissipation performance.

[0004] The present application provides a drain valve, comprising a valve body and a valve sleeve, wherein the tail end of the valve sleeve is provided with a cavity threadedly connected to the valve body, and the front end of the valve sleeve is sealed and connected to the drain joint of the water chamber; a first water channel is opened at the tail end of the valve body, and the first water channel is connected to the cavity; a second water channel is opened on the bottom surface of the cavity, and the second water channel is connected to the water chamber, and the front end of the valve body cooperates with the bottom surface of the cavity to control the opening and closing of the second water channel.

[0005] In the technical solution provided in the present application, the threaded connection between the valve body and the valve sleeve is utilized, and the second water channel can be closed or opened by tightening or loosening the valve body. The purpose of draining water can be easily achieved without completely unscrewing the valve body. The operation is convenient, and the wear of the drain valve thread can be greatly reduced, thereby extending the service life of the drain valve.

[0006] In some embodiments, a conical valve head is provided at the front end of the valve body, and the bottom surface of the cavity is a conical slope surface that abuts against the conical valve head; by designing the front end of the valve body and the bottom surface of the cavity to be conical surfaces that abut against each other, the sealing performance of the drain valve is greatly improved.

[0007] In some embodiments, a water inlet connecting the first water channel and the cavity is formed on the front end side wall of the valve body, and a gap is left between the outer wall of the valve body and the inner wall of the cavity at the water inlet; when the valve body is loosened, the second water channel is opened, and the water in the water chamber will flow into the gap and enter the first water channel through the water inlet, and finally be discharged from the drain valve.

[0008] In some embodiments, a nut is provided on the rear end fixing sleeve of the valve body to facilitate loosening or tightening the valve body with the help of a wrench.

[0009] In some embodiments, the valve sleeve is made of copper, and the valve body is made of aluminum alloy. By utilizing the material properties of the copper valve sleeve itself, the thread wear of the aluminum alloy valve body can be reduced, thereby improving the stability and durability of the drain valve.

[0010] In some embodiments, the front end of the valve sleeve is connected to the drain joint by threads, which facilitates the installation of the valve sleeve and the drain joint.

[0011] In certain embodiments, the threaded connection portion between the valve sleeve and the drain joint is fixed by glue, which further improves the stability and sealing of the connection between the valve sleeve and the drain joint.

[0026] Please continue reading Figure 2 , Figure 3 In some embodiments, a conical valve head 7 is provided at the front end of the valve body 1, and the bottom surface of the cavity is a conical slope 8 that abuts against the conical valve head 7; by designing the front end of the valve body 1 and the bottom surface of the cavity to be conical surfaces that abut against each other, the sealing performance of the drain valve is greatly improved.

[0027] Please continue reading Figure 2 , Figure 3 In some embodiments, a water inlet 9 connecting the first water channel 5 and the cavity is opened on the front end side wall of the valve body 1, and a gap 10 is left between the outer wall of the valve body 1 and the inner wall of the cavity at the water inlet 9; when the valve body 1 is loosened, the second water channel 6 is opened, and the water in the water chamber 3 will flow into the gap 10, and enter the first water channel 5 through the water inlet 9, and finally be discharged from the drain valve.

[0028] Please continue reading Figure 2 , Figure 3 In some embodiments, the outer wall of the valve body 1 is provided with an external thread, the inner wall of the cavity is provided with an internal thread matching therewith, the internal thread of the cavity does not extend to the bottom of the cavity, and a section of the inner wall of the cavity corresponding to the water inlet 9 is not provided with an internal thread; the front end of the valve seat is provided with an external thread, and the inner wall of the drain joint 4 is provided with an internal thread matching therewith.

[0029] Please continue reading Figure 2 , Figure 3 In some embodiments, a nut 11 is provided at the rear end fixing sleeve of the valve body 1 to facilitate loosening or tightening the valve body 1 with the help of a wrench.

[0030] In some embodiments, the valve sleeve 2 is made of copper, and the valve body 1 is made of aluminum alloy. By utilizing the material properties of the copper valve sleeve 2 itself, the thread wear of the aluminum alloy valve body 1 can be reduced, thereby improving the stability and durability of the drain valve.

[0033] The working principle of the drain valve in this embodiment is as follows:

[0034] When the drain valve needs to be closed, the valve body 1 is tightened (twist slightly forward a few times) so that the conical valve head 7 at the front end of the valve body 1 abuts against the conical slope 8 at the bottom of the cavity, thereby sealing the second water channel 6 and preventing the water in the water chamber 3 from leaking.

[0035] When it is necessary to open the drain valve to relieve the pressure in the water chamber 3, the valve body 1 is loosened (twist it lightly in the opposite direction for a few turns) so that the conical valve head 7 at the front end of the valve body 1 leaves the conical slope 8 at the bottom of the cavity. The second water channel 6 connects the cavity and the water chamber 3. The water in the water chamber 3 enters the cavity through the second water channel 6, and enters the water inlet 9 from the gap 10 between the cavity and the valve body 1, and then is discharged from the drain valve through the first water channel 5, thereby achieving the purpose of draining water.
