Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a self-draining valve. Background Technology

[0002] Valves are control components in fluid transport systems, with functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief. They are used in fluid control systems.

[0003] When a valve is used to transport fluid media for a long time, the fluid media tends to adhere to the inner wall of the valve cavity, forming deposits over time. This can cause blockage of the valve cavity and slow down fluid flow. The commonly used method for unblocking is to manually clean the inner wall of the valve cavity with a brush. This method requires stopping the valve from use and removing it separately, which is quite troublesome. Moreover, cleaning with a brush alone is not effective for some sticky deposits. Therefore, we propose a self-unblocking valve. Utility Model Content

[0004] The purpose of this invention is to provide a self-draining valve to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-draining valve, comprising a valve body, a valve cavity inside the valve body, a valve plate installed inside the valve cavity, an inlet at one end of the valve body, and an outlet at the other end of the inlet. A steam ring is installed inside the valve cavity at the inlet and outlet positions, and an annular steam chamber is installed inside the steam ring. Equally spaced steam nozzles are provided on the outer wall of one side of the steam ring. A bearing is installed inside the steam ring, and a cleaning ring is installed inside the bearing. A bracket is fixed inside the cleaning ring, and a turbine is installed at the center of the outer wall of the bracket. A connecting rod is fixed on the outer wall of the cleaning ring near the valve plate, and a cleaning rod is provided at one end of the connecting rod, with a cleaning brush on the surface of the cleaning rod. A steam pipe is installed at the top of the valve body at the steam ring position.

[0006] Preferably, the steam nozzles are arc-shaped and there are eight in total, and the steam nozzles are connected to the annular steam chamber.

[0007] Preferably, the bottom end of the steam pipe extends into the interior of the steam coil and communicates with the valve body, and a control valve is installed inside the steam pipe.

[0008] Preferably, one end of the cleaning rod is connected to the connecting rod via a pivot, and a torsion spring is fitted around the pivot, with both ends of the torsion spring connected to the pivot and the cleaning rod, respectively.

[0009] Preferably, the surface of the cleaning rod is provided with a strip-shaped groove, the cleaning brush is tightly engaged with the strip-shaped groove, and the cleaning brush is tightly fitted with the inner wall of the valve cavity.

[0010] Preferably, the turbine at the inlet is located on the side of the bracket closer to the inlet, and the turbine at the outlet is located on the side of the bracket away from the outlet.

[0011] Preferably, a positioning ring is provided on the side of the steam ring away from the valve plate, and the positioning ring is in close contact with the steam ring, the bearing, and the cleaning ring.

[0012] Preferably, a positioning bolt is provided on the inner wall of the positioning ring, and one end of the positioning bolt is threadedly connected to the valve body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The fluid medium flows from the inlet through the valve cavity inside the valve body and then out from the outlet. Under the impact of the liquid, the turbine rotates, causing the bracket to rotate the cleaning ring. The cleaning ring, through a connecting rod, drives the cleaning rod to rotate, which in turn drives the cleaning brush to clean the inner wall of the valve cavity, reducing the deposition of the fluid medium on the inner wall of the valve cavity. This design uses water flow as power to automatically clean the inner wall of the valve cavity without needing to stop using the valve or disassemble it separately, making it more convenient. After the valve is closed, the control valve is opened and the steam pipe is connected to the external steam pipeline, allowing high-pressure steam to enter the annular steam cavity inside the steam ring. The steam is evenly sprayed from the steam nozzle, which softens the sticky deposits on the inner wall of the valve cavity and peels off the adhering substances on the inner wall of the valve cavity, making it easier for the fluid medium to flow again. The deposits are then brushed off by the cleaning brush. This valve uses a combination of automatic cleaning and high-pressure steam peeling and softening to achieve an automatic unblocking effect and reduce valve cavity blockage.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-5 An embodiment of this utility model provides a self-draining valve, comprising a valve body 1, a valve cavity 2 inside the valve body 1, a valve plate 3 installed inside the valve cavity 2, an inlet 4 at one end of the valve body 1, and an outlet 5 at the other end of the inlet 4, a steam ring 6 inside the valve cavity 2 at the positions of the inlet 4 and the outlet 5, and an annular steam chamber 11 inside the steam ring 6, steam nozzles 12 at equal intervals on one side of the outer wall of the steam ring 6, a bearing 7 installed inside the steam ring 6, a cleaning ring 8 installed inside the bearing 7, a bracket 9 fixed inside the cleaning ring 8, a turbine 10 installed at the center of the outer wall of the bracket 9, a connecting rod 13 fixed on the outer wall of the cleaning ring 8 near the valve plate 3, a cleaning rod 16 at one end of the connecting rod 13, and a cleaning brush 17 on the surface of the cleaning rod 16;

[0024] Specifically, the control valve plate 3 opens, allowing the fluid medium to flow from the inlet 4 through the valve cavity 2 inside the valve body 1 and then out from the outlet 5. During this process, the impact of the liquid drives the turbine 10 to rotate, causing the bracket 9 to rotate the cleaning ring 8. The cleaning ring 8 drives the cleaning rod 16 to rotate through the connecting rod 13. The cleaning rod 16 drives the cleaning brush 17 to clean the inner wall of the valve cavity 2, reducing the deposition of fluid medium on the inner wall of the valve cavity 2. This design uses water flow as power and can automatically clean the inner wall of the valve cavity 2 without stopping the valve or removing the valve separately, making it more convenient.

[0025] A steam pipe 101 is installed on the top of the valve body 1 at the position of steam ring 6;

[0026] The steam nozzles 12 have an arc-shaped structure and there are eight in total. The steam nozzles 12 are connected to the annular steam chamber 11. The high-pressure steam ejected from the steam nozzles 12 adheres closely to the inner wall of the valve chamber 2, which can soften and peel off the deposits on the inner wall.

[0027] The bottom end of the steam pipe 101 extends into the interior of the steam ring 6 and communicates with the valve body 1, and a control valve 102 is installed inside the steam pipe 101.

[0028] Specifically, the control valve 102 is opened and the steam pipe 101 is connected to the external gas pipeline, so that high-pressure steam enters the annular steam chamber 11 inside the steam ring 6. The steam is evenly sprayed out from the steam nozzle 12, which can soften the sticky deposits on the inner wall of the valve chamber 2 and peel off the attachments on the inner wall of the valve chamber 2, so that when the fluid medium is circulated again, the deposits are brushed off by the cleaning brush 17. The valve adopts a combination of automatic cleaning and high-pressure steam peeling and softening, which achieves the effect of automatic unblocking and reduces the blockage of the valve chamber 2.

[0029] One end of the cleaning rod 16 is connected to the connecting rod 13 via a pivot 14, and a torsion spring 15 is fitted on the outside of the pivot 14. The two ends of the torsion spring 15 are connected to the pivot 14 and the cleaning rod 16, respectively. The pivot 14 and the torsion spring 15 are designed to facilitate the inward folding of the cleaning rod 16, making it easy to remove the cleaning rod 16 from the valve cavity 2. The surface of the cleaning rod 16 is provided with a strip-shaped groove 18, and the cleaning brush 17 is tightly engaged with the strip-shaped groove 18, and the cleaning brush 17 is tightly fitted to the inner wall of the valve cavity 2, making it easy to replace the cleaning brush 17.

[0030] The turbine 10 at the inlet 4 is located on the side of the bracket 9 close to the inlet 4, and the turbine 10 at the outlet 5 is located on the side of the bracket 9 away from the outlet 5; this facilitates the turbine 10's front contact with the water flow, thereby making it easier to drive the cleaning rod 16 to rotate.

[0031] A positioning ring 19 is provided on the side of the steam ring 6 away from the valve plate 3. The positioning ring 19 fits tightly with the steam ring 6, the bearing 7, and the cleaning ring 8, which facilitates the installation and fixing of the steam ring 6, the bearing 7, and the cleaning ring 8.

[0032] A positioning bolt 20 is provided on the inner wall of the positioning ring 19. One end of the positioning bolt 20 is threaded to the valve body 1, which facilitates the disassembly and assembly of the steam ring 6, bearing 7, and cleaning ring 8.

[0033] In this embodiment, during use: First, the control valve plate 3 opens, allowing the fluid medium to flow from the inlet 4 through the valve cavity 2 inside the valve body 1 and then out from the outlet 5. During this process, the impact of the liquid drives the turbine 10 to rotate, causing the bracket 9 to rotate the cleaning ring 8. The cleaning ring 8, through the connecting rod 13, drives the cleaning rod 16 to rotate. The cleaning rod 16 drives the cleaning brush 17 to clean the inner wall of the valve cavity 2, reducing the deposition of the fluid medium on the inner wall of the valve cavity 2. This design utilizes water flow as power to automatically clean the inner wall of the valve cavity 2 without requiring the valve to be shut down. It is simpler to remove the valve separately without having to do so. After the valve is closed, the control valve 102 is opened and the steam pipe 101 is connected to the external gas pipeline, so that high-pressure steam enters the annular steam chamber 11 inside the steam ring 6. The steam is evenly sprayed out from the steam nozzle 12, which can soften the sticky deposits on the inner wall of the valve chamber 2 and peel off the attachments on the inner wall of the valve chamber 2, so that when the fluid medium is circulated again, the deposits are brushed off by the cleaning brush 17. The valve adopts a combination of automatic cleaning and high-pressure steam peeling and softening, which achieves the effect of automatic unblocking and reduces the blockage of the valve chamber 2.

[0034] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
