Description

Technical Field

[0001] The utility model relates to the technical field of valve plates, in particular to an anti-cracking and high-temperature resistant valve plate structure. Background Art

[0002] High-temperature pipeline valves are the main mechanical components for controlling the transportation of fluids in pipes. They can be used in various hot air pipelines in industries such as building materials, electricity, glass, and light industry, such as: the secondary utilization of waste heat from boilers, kilns, and blast furnaces, as well as the treatment of flue gas and waste. In actual operation, they can achieve functions such as cutoff, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief, such as: opening and closing of pipelines through valve plate structures; and air volume regulation of the above-mentioned hot air pipelines. When the high-temperature regulating gate valve is working, the lower part of the valve plate is a high-temperature area, and the working environment is very harsh, usually subject to the impact of high-temperature gases above 1000°C.

[0003] After searching, the announcement number CN204879026U provides a valve plate structure for high-temperature pipeline valves, including a valve plate, a high-temperature zone, a sub-high-temperature zone and a first medium-temperature zone are arranged in the middle of the valve plate, the high-temperature zone is arranged at the bottom of the valve plate, the sub-high-temperature zone is arranged at the top of the high-temperature zone, and the first medium-temperature zone is arranged at the top of the sub-high-temperature zone. The high-temperature zone, the sub-high-temperature zone, the first medium-temperature zone and the second medium-temperature zone are provided with compartment casting seams filled with fiber paper between each other, and high-temperature pipelines are arranged inside. The practical new type adopts a multi-stage casting design. In actual use, it reduces the defects of the valve plate structure such as short service life and high maintenance cost caused by long-term high-temperature working environment, improves the performance and service life of the valve, and has considerable economic benefits. Compared with the existing valve plate structure, it has a long service life and low maintenance cost; its defect is that the valve plate is easily deformed due to long-term high temperature, and the deformation of the valve plate affects the sealing of the valve, causing smoke leakage. Therefore, it is particularly important to improve the existing valve plate structure and design a new anti-cracking and high-temperature resistant valve plate structure to solve the above-mentioned technical defects and improve the practicality of the overall valve plate structure.

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Example:

[0024] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0025] A crack-resistant and high-temperature resistant valve plate structure includes a valve plate body 1, a cooling pipe 2 is provided inside the valve plate body 1, two groups of support frames 3 are provided on the outside of the cooling pipe 2 and inside the valve plate body 1, and sealing blocks 4 are provided at both ends of the cooling pipe 2, multiple groups of reinforcing ribs 5 are provided inside the support frame 3, and an expansion space is formed between the support frame 3 and the valve plate body 1.

[0026] Furthermore, the cooling tube 2 is designed in a serpentine structure, and both ends of the cooling tube 2 extend to the outside of the valve plate body 1. When the valve plate body 1 is in use, cooling water is introduced into the cooling tube 2. The enclosed space inside the cooling tube 2 can reduce the temperature of the valve plate body 1 to prevent the valve plate body 1 from being too high in temperature during use, which may affect the flue gas leakage. A water pump is arranged on the outside of the valve plate body 1, and the water pump is connected to the cooling tube 2. New coolant is injected into the cooling tube 2. The flowing coolant can cool the coolant inside the cooling tube 2 to provide a cooling effect.

[0027] Among them, the external structure size of the sealing block 4 is designed to correspond to the internal structure size of the cooling tube 2. A plurality of sealing rings 6 are provided on the outside of the sealing block 4. The plurality of sealing rings 6 are evenly spaced on the outside of the sealing block 4 to connect the sealing block 4 to the cooling tube 2. When the sealing block 4 is connected to the cooling tube 2, the friction between the sealing block 4 and the cooling tube 2 can be increased through the plurality of sealing rings 6 on the outside, thereby increasing the sealing of the connection. The sealing block 4 allows a closed space to be formed inside the cooling tube 2, so that the coolant can be stored inside the cooling tube 2.

[0028] Furthermore, multiple groups of connecting grooves 7 are provided at the ends of the two groups of support frames 3 close to each other, and multiple groups of connecting columns 8 are provided at the ends of the two groups of support frames 3 close to the connecting grooves 7. The external structure size of the connecting column 8 is designed to correspond to the internal structure size of the connecting groove 7. The two groups of support frames 3 are connected to each other through the multiple groups of connecting grooves 7 and the connecting columns 8. The connecting columns 8 are connected to the connecting grooves 7 so that the two groups of support frames 3 can be connected. In conjunction with the multiple groups of reinforcing ribs 5, when the valve plate main body 1 is in use, the strength of the valve plate main body 1 can be increased through the two groups of support frames 3, and an expansion space is formed between the support frame 3 and the valve plate main body 1, which can give the valve plate main body 1 a certain amount of expansion, thereby preventing the valve plate main body 1 from cracking when it expands due to heat, thereby extending the service life of the valve plate main body 1.

[0029] Furthermore, the valve plate body 1 is composed of an upper shell 9 and a lower shell 10, and the two groups of support frames 3 are respectively located inside the upper shell 9 and the lower shell 10. When the upper shell 9 or the lower shell 10 is damaged, the design of the upper shell 9 and the lower shell 10 can smash the damaged upper shell 9 or the lower shell 10, and then disconnect the connection between the two groups of support frames 3 and replace them, thereby reducing maintenance costs.

[0030] Furthermore, a conduction plate 11 is provided inside the valve plate body 1 and on the outside of the support frame 3, a heat-resistant plate 12 is provided at one end of the conduction plate 11 away from the support frame 3, and heat-conducting blocks 13 are provided at both ends of the conduction plate 11 and the heat-resistant plate 12. When the conduction plate 11 is subjected to high temperature, the temperature on the heat-resistant plate 12 is heat-conducted. After the heat is conducted to the heat-conducting block 13, the heat-conducting block 13 dissipates the heat outward, thereby improving the high temperature resistance of the valve plate body 1. The conduction plate 11 is made of graphene, and the heat-conducting block 13 is made of graphite. After the heat is transferred to the heat-conducting block 13 through the conduction plate 11, the heat is conducted outward, thereby being able to dissipate heat for the valve plate body 1.

[0031] In this embodiment, the implementation scenario is specifically as follows: when the valve plate body 1 is in use, cooling water is introduced into the interior of the cooling tube 2. The enclosed space inside the cooling tube 2 can reduce the temperature of the valve plate body 1 to prevent the valve plate body 1 from being too hot during use, which may affect the leakage of flue gas. A water pump is arranged on the outside of the valve plate body 1, and the water pump is connected to the cooling tube 2. New coolant is injected into the interior of the cooling tube 2. The flowing coolant can cool the coolant inside the cooling tube 2 to provide a cooling effect. The sealing block 4 is connected to the cooling tube 2. When the sealing block 4 is connected to the cooling tube 2, the friction between the sealing block 4 and the cooling tube 2 can be increased through the multiple sets of sealing rings 6 on the outside, thereby increasing the sealing of the connection. The sealing block 4 can form an enclosed space inside the cooling tube 2, so that the coolant can be stored inside the cooling tube 2. When the valve plate body 1 is in use, the strength of the valve plate body 1 can be increased through the two sets of support frames 3. An expansion space is formed between the support frame 3 and the valve plate body 1, which can give the valve plate body 1 a certain amount of expansion, prevent the valve plate body 1 from cracking when it expands due to heat, and extend the service life of the valve plate body 1. When the valve plate body 1 is in use, the design of the upper shell 9 and the lower shell 10, when the upper shell 9 or the lower shell 10 is damaged, the damaged upper shell 9 or the lower shell 10 is broken, and then the connection between the two groups of support frames 3 is disconnected and replaced, which reduces the maintenance cost. When the conduction plate 11 is subjected to high temperature, the temperature on the heat-resistant plate 12 is heat-conducted to the heat-conducting block 13, and the heat-conducting block 13 dissipates heat outward, thereby improving the high temperature resistance of the valve plate body 1. The conduction plate 11 is made of graphene material, and the heat-conducting block 13 is made of graphite material. After the heat is transferred to the heat-conducting block 13 through the conduction plate 11, the heat is conducted outward, so that the valve plate body 1 can be heat-dissipated. Compared with the existing valve plate, the utility model can improve the overall practicality of the valve plate through design.
