1. Adopts no guide hole type flat structure, the valve stem adopts multi-thread, large lead, fast tightening speed, and the opening speed is more than twice that of ordinary thread. The compact structure and reasonable design reduce the overall weight and height of the valve and save the cost.
2. The flexible sealing ring is used to seal the valve seat and the floating seat structure of the pre-tightening force is applied, so that the opening and closing torque of the valve is only 1/2 of that of the ordinary valve, and the valve can be easily opened and closed.
3. When the valve is fully opened, the flow resistance coefficient is very small, and the valve will remove the action of the disc and the dirt on the sealing surface every time it is opened and closed.
4. The packing is made of flexible graphite ring and graphite packing, reliable sealing, light and flexible operation.
5. When the valve is closed, the gate valve without a diversion hole does not require high precision in the closing position of the gate plate
6. It is widely used in petrochemical, thermal power plants and other oil and water steam pipelines to connect or cut off the intermediate quality of the pipeline. The sealing surface of the opening and closing device has compact structure and reasonable design.

Q: What basic elements should be considered in valve selection?
A: The basic elements of valve selection need to be considered: 1 valve sealing performance, 2 valve types, 3 valve end connection forms, 4 valve materials, 5 flow through the valve.
Â
Q: What is the influence of medium temperature on valve design and selection?
A: The medium temperature has an impact on the valve design and selection: 1 selection of valve material, 2 selection of valve structure form, 3 selection of valve drive device.
Â
Q: What kinds of sealing surface materials are there? What are the main characteristics of various sealing surface materials?
A: Valve sealing surface material types are: hard sealing material, soft sealing material, grease sealing material; Hard seal can be applied to any working condition, hard seal material is the most common material used in the valve, with all the basic requirements of sealing surface material; Soft sealing material is mainly used in low temperature working conditions, reliable sealing, good corrosion resistance, small friction coefficient; Grease sealing material mainly through sealing grease to meet the sealing requirements, is an auxiliary seal, and the use of temperature is not high.
Â
Q: Bolts and nuts for the valve has an important role, bolts and nuts design and quality control need to pay attention to what problems?
A: The use temperature range of bolts, nuts and materials, such as high temperature and low temperature valves.
Â
Q: What is the meaning and function of the furnace number on the valve body?
A: The role of the batch number is traceability.
Â
Q: What is the meaning and function of the series number on the valve?
A: Indicates the nominal pressure, diameter and flow direction of the valve.
