1. Sealing performance of socket welded forged gate valve

Socket welded forged gate valves play a vital role in many industrial applications, especially when it comes to the interception and regulation of fluid piping systems. Among them, sealing performance is one of the key indicators to evaluate the quality of gate valves. How is the sealing performance of this gate valve formed? I will reveal them one by one for you below, bronze plug valve.

2. Design features and sealing principles

The design features of the socket welded forged gate valve are mainly reflected in its structural form and sealing principle. This kind of valve usually uses a flat gate or a wedge-shaped gate, and the fluid channel is opened and closed through the lifting movement of the gate. The formation of sealing performance mainly depends on the following aspects:

Sealing ring design: Socket welded forged gate valves adopt a unique sealing ring structure, usually made of elastic materials. When the valve is closed, the sealing ring is compressed between the gate plate and the valve seat, forming a reliable sealing barrier, bronze wafer check valve.

Matching of gate plate and valve seat: The matching accuracy of gate plate and valve seat is crucial to sealing performance. Through precise machining and grinding processes, the matching gap between the gate plate and the valve seat is ensured to be minimized, thereby achieving a good sealing effect.

Packing seal: Packing seal is another important line of defense for socket welded forged gate valves. By selecting appropriate packing materials and structural design, it is ensured that the valve can maintain stable sealing performance when subjected to pressure and temperature changes.

3. Manufacturing process and quality control

The manufacturing process of socket welded forged gate valves has an important impact on the formation of its sealing performance. The following are some key manufacturing processes and quality control aspects:

Forging process: Advanced forging process is used to ensure that the material of the gate valve is uniform and the density is moderate, thereby improving its mechanical properties and corrosion resistance.

Heat treatment process: Through appropriate heat treatment processes, such as quenching, tempering, etc., the metallographic structure and mechanical properties of the gate valve material are adjusted to meet the needs of different application scenarios.

Machining process: High-precision machining process is adopted to ensure that the machining accuracy and surface quality of the gate, valve seat and other key components meet the design requirements.

Inspection and testing: Strict inspection and testing are conducted on the manufactured socket welded forged gate valves, including dimensional inspection, pressure test, sealing performance test, etc., to ensure that they meet relevant standards and customer requirements, high temperature check valve.
