National standard high-pressure forged steel ball valve

Detailed description of the national standard high-pressure forged steel ball valve:

　　
The national standard high-pressure forged steel ball valve is a type of gate valve that is made by forging raw materials, and the relative density of the material is much higher than that of forging. It is particularly suitable for the production, manufacturing, and processing of high-pressure gate valves. The national standard high-pressure forged steel ball valve closing part is a type of gate valve that rotates around the centerline of the valve body to achieve opening and closing. The hydraulic seal is embedded in the stainless steel plate valve seat, and a spring yellow is set at the end of the metal material valve seat. When the protruding surface is worn or damaged, the spring yellow effect promotes the metal material sealing between the valve seat and the ball. It has a unique fully automatic pressure relief function. When the working pressure of the material in the chamber of the gate valve exceeds the pre tightening force of the spring yellow, the valve seat at the inlet and outlet will reverse and get rid of the spherical shape, achieving the actual effect of fully automatic pressure relief. After pressure relief, the valve seat will be fully automatically calibrated, and it can be used for general working substances such as strong electrolytes, organic solvents, acids, and gases, as well as standard extreme substances such as CO2, hydrogen peroxide, methane gas, and butadiene. It has been widely used in various fields.
　　

Characteristics of national standard high-pressure forged steel ball valve:

　　
Standardize the use of a spring yellow structure for valve seats, guiding them towards a spherical shape to ensure excellent dual sealing performance for import and export trade;
　　
The national standard high-pressure forged steel ball valve uses a built-in drain valve, and the inner chamber of the valve body can drain water outward;
　　
The pivot adopts anti blowing maintenance structure to reasonably avoid leakage; Low friction index rolling bearings minimize torque and facilitate the opening and closing of gate valves;
　　
Reasonable contact between the valve seat and valve body ensures excellent performance of the anti-static grounding system.
　　
It has the advantages of excellent performance, high reliability, universal main use, and affordable price.
　　

Overview of National Standard High Pressure Forged Steel Ball Valve:

　　
The three built-in national standard high-pressure forged steel ball valve divides the valve body into three parts along a cross-section perpendicular to the centerline of the safety passage of the gate valve at two valve seats. One gate valve manages the symmetry of the center axis up and down along the valve seat. The national standard high-pressure forged steel ball valve is key to disconnecting, distributing, and changing the direction of material flow on the pipeline. Its large pivot structure ensures precise spherical management of the central area under high pressure, ensuring excellent operational performance of the gate valve.
