Abstract
Description
Technical Field
[0001] This utility model relates to the field of cast iron valve body parts, and in particular to a reinforced cast iron valve body part. Background Technology
[0002] The valve body is one of the main components used in valves, controlling the flow of media within connected pipelines. It is a crucial part of pipeline construction. Valve bodies come in various styles and are typically manufactured using methods such as casting. The strength of the valve body refers to its ability to withstand media pressure. During use, the valve body is subjected to the impact of the media, which can severely affect its normal operation. Therefore, multiple reinforcing ribs are installed on the outside of the valve body to increase its load-bearing capacity and ensure long-term use without cracking or deformation. Traditional valve bodies often exhibit insufficient structural strength, high fluid resistance, and stress concentration under high-intensity, high-flow-rate, and high-pressure conditions, leading to shortened valve lifespan and even safety hazards. Therefore, there is an urgent need to develop a reinforced cast iron valve body that can improve the overall strength and stability of the valve body, disperse impact forces to reduce stress concentration, and extend valve lifespan.

A plurality of lower ribs are evenly and equidistantly arranged at the connection between the valve neck and the valve body. A plurality of upper ribs are evenly and equidistantly arranged at the connection between the valve neck and the third connecting flange.
[0007] Furthermore, the cross-sectional shape of the fixed rib and the connecting rib is trapezoidal or rectangular to enhance the overall strength and stability of the valve body structure.
[0008] Furthermore, the thickness of the lower and upper ribs gradually decreases from the valve neck towards the valve body and the third connecting flange to reduce stress concentration and improve structural durability.
[0009] Furthermore, the inner wall of the water passage of the valve body is provided with a spiral guide groove to optimize fluid flow and reduce fluid resistance.

Detailed Implementation
[0016] The present invention will be further described below with reference to the accompanying drawings: Example
[0017] A reinforced cast iron valve body, such as Figure 1-3 As shown, it includes a valve body 1, which is a cylindrical tubular structure with a water passage hole in the center; a valve neck 2 is fixedly provided on the outer diameter surface of the valve body 1, which is fixedly connected to the water passage hole of the valve body 1; a first connecting flange 3 and a second connecting flange 4 are respectively provided at both ends of the valve body 1, which are fixedly connected to the valve body; a third connecting flange 5 is provided at the end of the valve neck 2 away from the valve body.
[0018] A first reinforcing ring 6 and a second reinforcing ring 7, which are fixedly connected to the valve body, are also provided between the first connecting flange 3 and the second connecting flange 4. The first reinforcing ring 6 is located on the side of the valve body 1 closer to the first connecting flange 3, and the second reinforcing ring 7 is located on the side of the valve body 1 closer to the second connecting flange 4. A plurality of fixed ribs 8, which are connected to the first connecting flange 3, the first reinforcing ring 6, and the valve body, are evenly and equidistantly arranged between the first connecting flange 3 and the first reinforcing ring 6. A plurality of fixed ribs 8, which are connected to the second connecting flange 4, the second reinforcing ring 7, and the valve body, are evenly and equidistantly arranged between the second connecting flange 4 and the second reinforcing ring 7. A plurality of connecting ribs 9, which are connected to the first reinforcing ring 6, the second reinforcing ring 7, and the valve body, are also evenly and equidistantly arranged between the first reinforcing ring 6 and the second reinforcing ring 7. A plurality of lower ribs 10 are evenly and equidistantly arranged at the connection between the valve neck 2 and the valve body 1. A plurality of upper ribs 11 are evenly and equidistantly arranged at the connection between the valve neck 2 and the third connecting flange 5.
[0019] Working principle:
[0020] This utility model relates to a valve body. The valve body 1 is a cylindrical tubular structure with a central water passage for fluid passage. The valve neck 2 is fixedly connected to the water passage of the valve body 1. The first connecting flange 3 and the second connecting flange 4 at both ends of the valve body 1 are used for connection with other pipes or equipment. During operation, fluid enters the water passage of the valve body 1 from one end. Guided by the spiral guide groove, the fluid flow is optimized, reducing fluid resistance and improving flow efficiency. The design of the spiral guide groove causes the fluid to rotate as it passes through the valve, which helps to reduce turbulence and pressure loss. The first reinforcing ring 6 and the second reinforcing ring 7, as well as the fixed rib 8 and the connecting rib 9, enhance the overall strength and stability of the valve body structure, dispersing the impact force to the first reinforcing ring 6 and the second reinforcing ring 7, as well as the fixed rib 8 and the connecting rib 9, ensuring that the valve can maintain structural integrity and functional stability under high pressure or high flow rate conditions; the thickness of the lower rib 10 and the upper rib 11 gradually decreases from the valve neck 2 towards the valve body 1 and the third connecting flange 5, reducing stress concentration, improving structural durability, and extending the service life of the valve.
