Welded gate valve is a widely used valve in the industrial field, which plays an important role in multiple industrial fields due to its simple structure, good sealing performance, small working stroke, and short opening and closing time. The following is a detailed explanation of the application of welded gate valves:

1、 Main application areas

1. Petroleum and chemical industry: In the field of petroleum and chemical industry, welded gate valves are mainly used to control the flow of fluids, prevent medium leakage, and ensure production safety. For example, in the oil and gas industry, welded gate valves are commonly used for controlling pipeline systems to prevent fluid leakage or backflow. In chemical production, it is used to control the flow of various corrosive media.

2. Water treatment: In the field of water treatment, welded gate valves are used to regulate water quality, flow rate, and pressure to meet different process requirements. For example, in water treatment systems, welded gate valves can be used to control water flow and prevent water backflow.

3. Electricity: In the field of electricity, welded gate valves are used to control the flow of steam, water, and other media, ensuring the stable operation of the power system. For example, in the power industry, welded gate valves are mainly used on various pipelines of thermal power plants to cut off or connect pipeline media.

4. Metallurgy: In the metallurgical industry, welded gate valves are used to control the flow of high-temperature and high-pressure fluids.

5. In other fields such as semiconductors, chemistry, medicine, and aerospace, welded gate valves also play an important role in controlling gas flow and ensuring the normal operation of precision instruments.

2、 Application features

1. Good sealing performance: The welded gate valve adopts a welding connection method to ensure a tight fit between the valve body and the pipeline, thereby providing excellent sealing performance. In addition, its sealing surface is usually welded with cobalt based hard alloy, which has good wear resistance and abrasion resistance, further improving the sealing performance.

2. Easy to operate: Welded gate valves drive the gate by rotating the valve stem, thereby achieving the opening and closing of fluids. Easy and fast operation, short opening and closing time, which is conducive to improving work efficiency.

3. Wide applicability: Welded gate valves are suitable for various liquid, gas, and steam media, and have stable and reliable operating performance in harsh environments such as high temperature, high pressure, and strong corrosion.

3、 Selection precautions

When selecting welded gate valves, the following factors need to be considered:

1. Medium characteristics: Select appropriate materials and sealing structures based on the properties of the medium (such as temperature, pressure, corrosiveness) to ensure the corrosion resistance and sealing performance of the valve.

2. Working conditions of pipeline system: Select the appropriate nominal diameter and pressure rating of valves based on the working pressure, temperature, and other conditions of the pipeline system to ensure stable operation of the valves.

3. Operation mode and actuator: Choose the appropriate operation mode and actuator (such as manual, electric, pneumatic, etc.) according to the actual usage situation to meet different control requirements.

Welded gate valves are widely used in the industrial field due to their superior performance and wide range of applications. In the selection and use process, it is necessary to comprehensively consider the actual situation to ensure the normal operation and long-term stability of the valve.
