China valve industry product development direction trend analysis

According to the analysis of domestic and foreign valve technology and domestic and foreign valve market demand, there are ten product development trends of China's valve industry in the next few years

 

 

1. Valves for oil and natural gas wellhead devices

The valves used for oil and natural gas wellhead devices are mainly single or double gate plates conforming to the American API6A standard, forged steel parallel gate valves with or without diversion holes, mud valves, Angle throttle valves, parallel control valves for oil fields, straight through check valves for oil fields, parallel water injection/polymer gate valves, clamp-type parallel gate valves, pilot safety valves and check valves.

 

2. Valves for oil and natural gas long distance pipelines

The valves used in oil and natural gas long-distance pipelines are mainly single or double gate valves, with or without diversion holes, which meet the American API6D standard. Forged or cast steel three-type, top or all welded fixed ball valve; Oil seal or pressure balanced plug valve; Swing or butterfly check valve, through ball check valve; Pigging valve, etc.

 

3. Nuclear power valve

The valves used in nuclear power plants have higher technical characteristics and requirements than those used in conventional large thermal power plants. Valves are generally gate valves, globe valves, check valves, butterfly valves, safety valves, main steam isolation valves, ball valves, diaphragm valves, pressure reducing valves and control valves.

 

4. Offshore oil valves

The oil recovery, blowout prevention, water injection, gas injection, underwater equipment and other systems of offshore oil production platform need to develop some special valves that are resistant to seawater and salt spray erosion requirements. These valves require a strong ability to resist corrosion, storm and other abnormal external forces, and require reliable sealing, flexible operation and easy maintenance. The main ones are forged steel single or double gate with or without diversion hole flat gate valve, double butterfly check valve, Angle throttle valve with pressure balance valve stem, etc.

 

5. Petrochemical and electric power valves

Petrochemical, power valve products, the focus of its structural adjustment is the development of missing products. There are mainly high temperature and high pressure regulating valve, temperature reducing pressure reducing valve, high temperature and high pressure large diameter safety valve, high pressure steam trap and so on.

 

 

6. Environmental protection valve

The environmental protection system needs to develop valves: ceramic disc sealed rotary valve, PVC plastic valve, large sealing surface flat gate valve, stainless steel plug valve, etc.

 

7. Valves for metallurgical systems

Valve for metallurgical system, because the medium is often powdery and suspended solid particles, coupled with high temperature, it has higher requirements for wear resistance, temperature resistance and corrosion resistance of the valve. The main dome valve, ash discharge plate gate valve, strong acid corrosion resistant stainless steel valve.

 

8. Valves for alumina industry

In the production process of alumina industry, the medium is mostly alkaline mud and granular matter, the scarring phenomenon is extremely serious, and the erosion phenomenon of the medium on the valve body cavity and the inner part is also very serious. Therefore, the alumina industrial valve is required to be resistant to scarring. Resistance to erosion.

The slurry valve (straight-through globe valve), which integrates the gate valve, globe valve and ball valve of common structure in alumina production system, is not only resistant to scarring, but also resistant to erosion and erosion, which is the ideal product for alumina production valve.

 

9. Valves for large chemical plants

Large chemical plants are mainly ethylene, synthetic ammonia, air separation and other plants. There are mainly valves for ethylene plants, valves for synthetic ammonia plants, valves for air separation plants, etc.

 

10. City construction valve

Urban construction valves will show the following trends: The development of urban gas generating units fuel gas cut off ball valves; Developing middle-line butterfly valves and soft-seal gate valves that replace ordinary butterfly valves, low-pressure gate valves and globe valves in urban water supply and heating systems; Development of automotive liquefied petroleum gas, liquefied natural gas-gasoline cylinder valves. The development of urban apartment heating, air conditioning hydraulic balance valve, intelligent instrument and heat metering valve. The development of urban gas pipe network with safety release valve, electric flow control valve, gas-liquid linkage emergency cut off ball valve.
