Main Applications of Nine Valves
1.Valves for petroleum installations
* Oil refining equipment
Most of the valves used in oil refining equipment are pipeline valves, mainly including gate valve, globe valve, check valve, safety valve, ball valve, butterfly valve, and trap valve. Gate valve demand accounts for about 80% of the total number of valves (valve accounts for 3% to 5% of the total investment of the device).
* Chemical fiber plant contraction
Chemical fiber products are mainly polyester, acrylic, vinylon three categories. Ball valve, jacket valve (jacket ball valve, jacket gate valve, jacket globe valve) of the valve needed;
* Acrylic clear device
The device generally needs to use the valve is mainly gate valve, globe valve, check valve, ball valve, trap, needle globe valve, plug valve, gate valve accounted for about 75% of the total number of valves;
* Synthetic ammonia equipment
Since the ammonia synthesis and purification methods are different and the process is different, the technical function of the valve is different. At present, gate valve, globe valve, check valve, trap valve, butterfly valve, ball valve, diaphragm valve, regulating valve, needle valve, safety valve, high temperature, and low-temperature valve are mainly needed in the domestic ammonia synthesis device;
2.Valves for hydropower station
At present, the construction of the power station is developing towards a large scale. Therefore, large diameter and high-pressure safety valve, pressure reducing valve, globe valve, gate valve, butterfly valve, emergency shutoff valve, flow control valve and globe sealing instrument globe valve are required.
3.Valves for metallurgy
Aluminum oxide behavior in the metallurgical industry mainly requires the use of abrasion-resistant slurry valve (flow globe valve), regulating the trap. Sealed ball valve, butterfly valve and oxidation ball valve, globe flash and four-way reversing valve are mainly needed in the steel-making industry;
4.Valves for Marine service
With the development of offshore oil field exploitation, the number of valves needed for offshore flat development gradually increases. Shutoff ball valve, check valve and multiway valve shall be used for the offshore platform;
5.Valves for food and medicine
Valve used in the food and medicine industry is mainly stainless steel sanitary ball valve, non-toxic plastic ball valve, and sanitary butterfly valve, etc. In 9 kinds of valve products, the demand for general valves is relatively large, such as instrument valve, needle valve, needle globe valve, gate valve, globe valve, check valve, ball valve, and butterfly valve;
6.Valves for rural and urban building
Low-pressure valves are commonly used in urban construction systems and are now being developed in the direction of environmental protection and energy saving. Environment-friendly plastic plate valve, balance valve and the middle line butterfly valve, and the metal sealing butterfly valve are gradually replacing the low-pressure iron gate valve. Most of the valves used in urban construction are balance valve, soft seal gate valve, butterfly valve, etc.
7.Valves for environmental protection
In the Marine environmental protection system, centerline butterfly valve, the soft seal gate valve, the ball valve, and the exhaust valve (used to remove the air in the pipeline) are needed. The valves needed to be used in the sewage treatment system are the soft seal gate valve and the butterfly valve.
8.Valves for gas control
Valves for urban gas account for 22 percent of the total natural market, which requires a large number of valves and various types, such as the ball valve, plug valve, pressure relief valve, safety valve, etc.
9.Valves for Pipeline service
Long-haul pipelines are mainly crude oil, finished products, and natural pipelines. The value of this kind of pipeline dosage is forging steel three-piece full-size ball valve, sulfur resistant plate gate valve, safety valve, check valve.
