The inner wall of the valve body has an inlet chamber and a drain chamber, which are connected. A limiting groove is formed in the inner wall of the inlet chamber, and the impact-resistant plate abuts against the limiting groove, with its outer peripheral wall in sliding contact with the inner wall of the limiting groove. Multiple flow holes are formed on the outer wall of the impact-resistant plate, with the diameter of the flow holes increasing from the middle to both ends. In this utility model, by setting up the impact-resistant plate, the impact force of the fluid is transferred from the inner wall of the valve body to the impact-resistant plate, avoiding direct impact on the valve body.

[0002] In industries such as petrochemicals and energy, high-temperature and high-pressure valve bodies are key components of fluid transport systems, playing a crucial role in controlling and regulating fluid flow rate, pressure, and direction. During actual operation, the fluid inside the valve body has high velocity and pressure. When the fluid enters or changes its flow direction, it exerts a strong impact on the internal structure of the valve body, especially under high-pressure environments, where this impact force is even more significant.

[0003] When high-speed, high-pressure fluid enters the valve body, it directly impacts the internal wall of the valve body. Over time, this can lead to fatigue and wear of the valve body material, and even cracks, which can cause leaks and other safety hazards, affecting the service life and operational safety of the equipment.

[0026] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] In this utility model, unless otherwise explicitly specified and limited, the term "fixed connection" should be interpreted broadly. For example, "fixed connection" can mean fixed installation, detachable connection, or integral connection; it can mean mechanical connection or electrical connection; it can mean direct connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, an impact-resistant high-temperature and high-pressure valve body includes a valve body 1 and an impact-resistant plate 9;

[0029] The valve body 1 has an inlet chamber 2 and a drain chamber 3 on its inner wall. The inlet chamber 2 and the drain chamber 3 are connected. The inlet chamber 2 has a limit groove 4 on its inner wall.

[0030] The impact-resistant plate 9 rests against the limiting groove 4, and its outer peripheral wall slides in contact with the inner wall of the limiting groove 4. The outer wall of the impact-resistant plate 9 has multiple flow holes 10, and the diameter of the flow holes 10 increases from the middle to both ends. The gradually expanding structure at both ends of the flow holes 10 can reduce the outlet flow velocity, and the narrow section in the middle forms a turbulent boundary layer to dissipate impact energy.

[0031] By setting the anti-impact plate 9, the impact force of the fluid is transferred from the inner wall of the valve body 1 to the anti-impact plate 9, avoiding the valve body 1 from directly bearing the impact; the design of the flow hole 10 with the diameter increasing from the middle to both ends reduces the flow velocity and disperses the pressure when the fluid passes through, further reducing the impact of the fluid on the valve body, preventing fatigue, wear and cracks in the valve body material, extending the service life of the valve body and ensuring the safe operation of the equipment.

[0032] like Figure 1and Figure 2 As shown, the outer walls at both ends of the valve body 1 are provided with multiple flange holes 8, and the top of the valve body 1 is provided with multiple connection holes 7. The flange holes 8 at both ends of the valve body 1 facilitate connection to pipelines via flanges, enabling the assembly of the valve body with the entire fluid transport system. The top of the valve body 1 is provided with a connection groove 5, and the inner wall of the connection groove 5 is provided with a sealing groove 6. The connection groove 5 and the sealing groove 6 provide a positioning and sealing structure for the installation of the connecting plate 11. The impact-resistant high-temperature and high-pressure valve body also includes a connecting plate 11, the top of the connecting plate 11 is provided with multiple mounting holes 12, and multiple bolts 18 are inserted into the inner wall of the mounting holes 12. The bottom of the bolts 18 penetrates the connection holes 7 and extends below them, and the ends of the bolts 18 are threaded with nuts 19.

[0033] like Figure 1 , Figure 2 and Figure 5 As shown, multiple support rods 16 are fixedly connected to the top of the connecting plate 11, and a tray 17 is fixedly connected to the top of the support rods 16. A connector 13 is fixedly connected to the bottom of the connecting plate 11. The connector 13 is engaged with the connecting groove 5. Multiple first sealing rings 14 are sleeved on the outer wall of the connector 13. The first sealing rings 14 are engaged with the inner wall of the sealing groove 6. A valve stem 20 is slidably connected to the inner wall of the connecting groove 5. The bottom of the valve stem 20 passes through the valve body 1 and extends into the drain chamber 3. A sealing plug 22 is provided in the drain chamber 3. The sealing plug 22 is fixedly connected to the valve stem 20. The top of the valve stem 20 passes through the connector 13 and the connecting plate 11 and is slidably connected to them. The top of the valve stem 20 passes through the tray 17 and is threadedly connected to it. A handwheel 21 is fixedly connected to the outer wall of the valve stem 20. The first sealing ring 14 on the outer wall of the connector 13 engages with the sealing groove 6 to form a sealing barrier, preventing fluid from leaking from the connection between the connector 11 and the valve body 1. This ensures the sealing performance of the valve body under high temperature and high pressure conditions, prevents fluid leakage from causing safety accidents, and guarantees the normal operation of the equipment.

[0034] like Figure 3 and Figure 5 As shown, the valve stem 20 is slidably connected to the inner wall of the connecting groove 5 and extends through the valve body 1 into the drain chamber 3. The position of the sealing plug 22 is controlled by the up and down movement of the valve stem 20, thereby realizing the opening and closing operation of the valve body and controlling the flow of fluid. A pressure groove 15 is provided on the top of the connecting plate 11, and a fixed plate 23 is fixedly connected to the outer wall of the valve stem 20. A limit ring 24 is fixedly connected to the bottom of the fixed plate 23. The limit ring 24 is engaged with the pressure groove 15. The limit ring 24 can further limit the valve stem 20 and improve the stability of the sealing plug 22 when sealing.

[0035] Working principle: When high temperature and high pressure fluid passes through the impact-resistant high temperature and high pressure valve body, it first enters the inlet chamber 2. At this time, the fluid cannot directly impact the inner wall of the valve body 1, but first impacts the impact-resistant plate 9. When the fluid enters the flow hole 10, as the diameter of the hole decreases, the flow rate of the fluid gradually decreases and the pressure is also dispersed, thereby effectively buffering the impact of the fluid on the inside of the valve body.

[0036] When it is necessary to close the valve body, turn the handwheel 21 to drive the valve stem 20 to rotate and move downward, so that the sealing plug 22 blocks the outlet of the drain chamber 3 and prevents the fluid from flowing out;

[0037] When the valve body needs to be opened, the handwheel 21 is turned in the opposite direction, and the valve stem 20 drives the sealing plug 22 to move upward. After the fluid passes through the anti-impact plate 9 for buffering, it flows out from the drain chamber 3.

[0038] The connecting plate 11 is fixedly connected to the connecting hole 7 on the top of the valve body 1 by bolts 18 and nuts 19. The first sealing ring 14 on the outer wall of the connector 13 is engaged with the sealing groove 6 to ensure the sealing between the connecting plate 11 and the valve body 1.

[0039] When the sealing plug 22 blocks the outlet of the drainage chamber 3, the limiting ring 24 at the bottom of the fixed plate 23 engages with the pressure groove 15.

[0040] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
