I hope that everyone can have a deeper understanding of the sealing performance of ISO 15761 gate valves and the considerations behind them, and provide valuable reference for related engineering applications. Gate valve, as a fluid control device, its sealing performance is crucial. ISO 15761 is a standard developed by the International Organization for Standardization for metal-sealed gate valves. It is of great significance for ensuring the quality and performance of gate valves, gate valve factory

1. ISO 15761 gate valve sealing performance test method

In order to ensure that the sealing performance of the gate valve meets the standard, the ISO 15761 standard stipulates a series of test methods. These include pressure tests, leak tests, air tightness tests, etc. These test methods not only cover a variety of possible operating conditions, but also take into account the actual needs of the valve in different application environments. Through these tests, the sealing performance of the gate valve can be comprehensively evaluated to ensure that it can meet engineering requirements in actual applications.

2. Factors affecting the sealing performance of ISO 15761 gate valve

The sealing performance of gate valves is affected by many factors. Here are some of the main factors:

Valve body materials: Different materials have different physical and chemical properties, which will affect sealing performance. For example, some materials are prone to deformation or creep in high-temperature or high-pressure environments, thereby reducing sealing performance. Therefore, when selecting valve body materials, its stability in practical applications needs to be fully considered, bronze valve supplier.

Sealing material: The selection of sealing material is crucial to ensure the sealing performance of the gate valve. Commonly used sealing materials include polytetrafluoroethylene (PTFE), rubber and metal seals. These materials show different performance characteristics under different application environments and working conditions. When selecting sealing materials, there are trade-offs based on actual application requirements.

Processing accuracy: The processing accuracy of the gate valve has a direct impact on its sealing performance. For example, if the dimensional accuracy and parallelism of the gate are insufficient, it may lead to poor fit between it and the valve seat, thereby reducing the sealing performance. Therefore, it is necessary to strictly control the processing accuracy during the manufacturing process to ensure that the quality of the gate valve meets the standard.

Installation and operation: Proper installation and operation are critical to ensuring the sealing performance of the gate valve. For example, installation should ensure that the valve is in the correct position and orientation to avoid stress concentrations and risk of leakage. During operation, attention should be paid to controlling the opening and closing speed to avoid excessive impact and wear on the valve, check valve factory.

3. Sealing performance of ISO 15761 gate valve in practical applications

In practical applications, ISO 15761 gate valves show good sealing performance under various working conditions. However, in some special cases, such as high temperature and high pressure, highly corrosive media, or fluids containing solid particles, targeted design and material selection may be required to ensure the sealing performance of the gate valve. In addition, during long-term operation, the sealing performance of the gate valve may be affected by wear, aging and other factors and gradually decrease. Therefore, regular inspection and maintenance are essential to maintain good sealing performance of the gate valve.

4. The following is a summary of what I share with you based on my many years of experience

Through an in-depth analysis of the sealing performance of ISO 15761 gate valves, I can draw the following conclusions: The ISO 15761 standard provides a strong guarantee for ensuring the sealing performance of gate valves. By following this standard for testing and evaluation, you can ensure that gate valves meet engineering requirements in practical applications. There are various factors that affect the sealing performance of ISO 15761 gate valves, which need to be fully considered and controlled in all aspects of design, manufacturing, installation and operation, wholesale globe valve.

In practical applications, ISO 15761 gate valves show good sealing performance under various working conditions. In special application environments and during long-term operation, additional measures may be required to maintain good sealing performance.
