Description

Technical Field

[0001] The present invention relates to the technical field of casting valves, and particularly to a casting valve with an explosion-proof and heat-dissipating structure. Background Technique

[0002] Casting is a process of melting metal into a liquid meeting certain requirements and pouring it into a mold, and after cooling and solidifying, and finishing treatment, a casting with a predetermined shape, size, and performance is obtained. A casting valve is a valve formed by casting. Generally, the pressure rating of a casting valve is relatively low, and the caliber is generally large. A forging valve is forged and is generally used in pipelines with a high rating and a relatively small caliber.

[0003] When a casting valve is in use, if the internal pressure is too high, it is easily damaged. Therefore, it needs to be improved to make it more convenient to use. Summary of the Invention

[0004] The purpose of the present invention is to provide a casting valve with an explosion-proof and heat-dissipating structure to solve the problem of poor protection of the casting valve proposed in the above background technique.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A casting valve with an explosion-proof and heat-dissipating structure, including a valve body, a ball core, and a handle. On both sides inside the valve body, side platforms are installed. Inside the side platforms, a first flow channel is provided. Inside the side of the side platforms, a ball core is provided. Inside the ball core, a second flow channel is provided. On both sides of the valve body, side pipes are fixed. On one side of the side pipes, flange plates are fixed. On the top of the valve body, a valve cover is installed. On the top of the valve cover, fixing bolts are provided. At the center position on the top of the valve cover, a positioning platform is fixed. Inside the positioning platform, a valve rod is provided. The bottom end of the valve rod is fixedly connected to the top end of the ball core. On the top end of the valve rod, a handle is installed. On the top of the side pipes, a pressure relief pipe is installed. At the bottom end inside the pressure relief pipe, a limiting platform is fixed. Inside the limiting platform, a pressure relief hole is provided. Inside the pressure relief pipe, a sealing plug is provided. On the top of the sealing plug, a spring is installed. On the top of the pressure relief pipe, an adjusting cap is provided. On one side of the pressure relief pipe, a discharge pipe is installed.

[0007] Preferably, a heat-conducting plate is fixed at the bottom end of the side pipe, and heat-dissipating fins are fixed on the surface of the heat-conducting plate.

[0008] Preferably, a number of heat-dissipating fins are fixed on the surface of the heat-conducting plate, and the number of heat-dissipating fins is evenly distributed.

[0014] By providing a heat conducting plate and heat dissipation fins, the heat conducting plate is located at the bottom of the side pipe, and multiple groups of heat dissipation fins are located on the surface of the heat conducting plate. During use, it can assist the side pipe in heat dissipation treatment, avoid the overall temperature of the valve from being too high, and enhance the heat dissipation property of the casting valve during use;

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4 , an embodiment provided by the present invention: a casting valve with an explosion-proof and heat dissipation structure, including a valve body 1, a ball core 4 and a handle 14. Side platforms 2 are installed on both sides inside the valve body 1. A first flow channel 3 is arranged inside the side platform 2. A ball core 4 is arranged inside the side of the side platform 2. The cross-section of the ball core 4 is smaller than that of the side platform 2. The ball core 4 and the side platform 2 form a rotating structure. A second flow channel 5 is arranged inside the ball core 4. Side pipes 6 are fixed on both sides of the valve body 1. A heat conduction plate 7 is fixed at the bottom of the side pipe 6. Heat sinks 8 are fixed on the surface of the heat conduction plate 7. A plurality of heat sinks 8 are fixed on the surface of the heat conduction plate 7, and the plurality of heat sinks 8 are evenly distributed at equal intervals;

[0023] Specifically, as Figure 1 and Figure 2 shown, during use, the heat conduction plate 7 is located at the bottom of the side pipe 6, and multiple groups of heat sinks 8 are located on the heat conduction plate 7. The heat inside the side pipe 6 is transferred to the multiple groups of heat sinks 8 through the heat conduction plate 7, and the multiple groups of heat sinks 8 can assist in heat dissipation treatment;

[0024] One side of the side pipe 6 is fixed with a flange 9. The top of the valve body 1 is installed with a valve cover 10. The top of the valve cover 10 is provided with a fixing bolt 11. At the center position of the top of the valve cover 10, a positioning platform 12 is fixed. Inside the positioning platform 12, a valve rod 13 is arranged. The bottom end of the valve rod 13 is fixedly connected to the top end of the ball core 4. The top end of the valve rod 13 is installed with a handle 14. Inside the handle 14, a storage groove 15 is arranged. Inside the storage groove 15, a limiting block 16 is arranged. The surface of the limiting block 16 is provided with an external thread. One side inside the storage groove 15 is provided with an external thread. One side of the limiting block 16 is installed with an extension rod 17. The cross-section of the extension rod 17 is smaller than the cross-section of the storage groove 15. The extension rod 17 and the storage groove 15 form a telescopic structure. One side of the extension rod 17 is installed with a convex block 18;

[0025] Specifically, as Figure 1 , Figure 2 and Figure 3 shown, when in use, after manually pulling out the extension rod 17, the extension rod 17 can be rotated. The limiting block 16 and the storage groove 15 are connected by threads. At this time, the extension rod 17 and the handle 14 cooperate to increase the overall length, which can assist the operator to rotate the handle 14;

[0026] The top of the side pipe 6 is installed with a pressure relief pipe 19. At the bottom end inside the pressure relief pipe 19, a limiting platform 20 is fixed. Inside the limiting platform 20, a pressure relief hole 21 is arranged. Inside the pressure relief pipe 19, a sealing plug 22 is arranged. The cross-section of the sealing plug 22 is smaller than the cross-section of the pressure relief pipe 19. The sealing plug 22 and the pressure relief pipe 19 form a sliding structure. The top end of the sealing plug 22 is installed with a spring 23. The top of the pressure relief pipe 19 is provided with an adjusting cap 24. One side of the pressure relief pipe 19 is installed with a discharge pipe 25;

[0027] Specifically, as Figure 1 , Figure 2 and Figure 4 shown, when in use, if the pressure inside the side pipe 6 is too high, the sealing plug 22 can be pushed upward to open the discharge pipe 25. At this time, the medium inside the side pipe 6 can be discharged through the discharge pipe 25, reducing the pressure inside the side pipe 6.

[0028] Working principle: During use, rotate the handle 14, drive the ball core 4 to rotate through the valve stem 13. When the second flow channel 5 inside the ball core 4 is docked with the first flow channels 3 on both sides, the internal channel is opened, and the valve opening operation can be completed. The extension rod 17 at the side end can also be manually pulled out and slightly rotated. Through the threaded fit between the limit block 16 and the storage groove 15, the position of the extension rod 17 is fixed. The extension rod 17 cooperates with the handle 14, and the overall length increases, which can assist the operator in rotating the handle 14. If the pressure inside the side pipe 6 is too high, the sealing plug 22 can be pushed upward through the pressure relief hole 21. The sealing plug 22 moves upward, and the discharge pipe 25 at the side end is opened. The medium inside the side pipe 6 can be discharged through the discharge pipe 25. The discharge pipe 25 can be connected to the corresponding container to collect and process the discharged substances. A heat conducting plate 7 and heat dissipation fins 8 are installed on the bottom surface of the side pipe 6. The multiple groups of heat dissipation fins 8 can assist in dissipating heat from the side pipe 6 and reduce the temperature inside the side pipe 6.
