Analysis of the development prospect of flange gate valve Market

In recent years, with the continuous development of gate valve market economy, China's domestic gate valve market also fluctuates. The economic market has not been particularly stable, so has the domestic and foreign market. The relative export of flange gate valve industry has weakened. However, in the next 5-10 years, with the enhancement of China's overall strength and the upcoming G20 Summit (International Economic Cooperation Forum), the overall economic level will show an upward trend. At the same time, the mechanical gate valve industry will slowly pick up.

In the next few years, the development of gate valve industry will be biased to flange gate valve according to authoritative analysis. Flange gate valve is a kind of valve which uses a ball with a circular passage as the opening and closing part, and the ball rotates with the stem to realize the opening and closing action. The opening and closing part of the gate valve is a sphere with holes, which rotates around the axis perpendicular to the channel, so as to achieve the purpose of opening and closing the channel. Gate valve is mainly used to open and close pipeline and equipment medium.

The types of flange gate valves are relatively diversified. Gate valves can be divided into floating gate valve, fixed gate valve, elastic gate valve and oil seal gate valve according to their structural forms; they can be divided into direct energy type, angle type and three-way type according to their channels, and the three-way type can be divided into T-shape and L-shape. According to the connection, it can be divided into threaded connection, flange connection and welding type. According to the driving mode, there are stainless steel pneumatic gate valve, stainless steel electric gate valve and manual gate valve.

The main advantages of flange gate valve are as follows:

1. It has the advantages of simple structure, small volume, light weight and easy maintenance;

2. Good sealing performance;

3. It is suitable for frequent operation, quick opening and closing, and light weight;

4. The fluid resistance is small;

5. It is not limited by the installation direction, and the flow direction of the medium can be arbitrary;

6. No vibration, low noise.

The working principle of the flange gate valve is that the valve is unblocked or blocked by rotating the valve core. The flange gate valve has the advantages of light switch, small volume, large diameter, reliable sealing, simple structure and convenient maintenance. The sealing surface and spherical surface are often closed and not easy to be eroded by the medium, so it is widely used in various industries.

Because of the great advantages and variety of flange gate valve, it is predicted that flange gate valve will be the most important product in the development of gate valve industry in the next few years. In addition, with the continuous improvement of people's living standards, stainless steel valves also play a huge role in the civil field, and the market is also expanding.
