The fully welded heating ball valve is widely used in urban heating systems, water and steam supply of thermoelectric pipelines, petrochemical, petroleum, natural gas, pharmaceuticals and other fields, as an on/off control device. The valve body adopts a fully welded structure formed by pressing high-strength carbon steel seamless steel pipes or steel plates; The sphere has two structures: floating and fixed; The sealing structure of the valve seat is designed as a multi-stage sealing structure with single or double soft sealing rings, ensuring reliable sealing and long-term stable operation of this series of ball valves.
Structural characteristics
1. The valve stems are made of high-performance stainless steel materials with good corrosion resistance. The sealing materials are fluororubber (FPM) and carbonized Teflon (PTFE+C), which have the characteristics of high strength, high temperature and pressure resistance, and corrosion resistance. The valve body material is made of high-strength carbon steel, which is the same as the pipeline, without uneven stress or deformation caused by earthquakes or vehicles passing through the ground. The pipeline is resistant to aging, and other connection methods such as flanges can be selected according to customer needs;
2. The ball is made of high-performance stainless steel, and the entire processing process is tracked and detected by advanced computer detectors. Therefore, the processing accuracy of the ball is very high, making it easy to operate and free from adverse interference;
3. The valve stem adopts explosion-proof design for use;
4. The entire assembly process of the valve is completed in a constant temperature state, with guaranteed product quality;
5. Compared with products of the same specification in the same industry, the valve body design, small appearance, and aesthetics;
6. The service life of the valve should be over 20 years while ensuring its normal operation and use.
