Following with various need of the modern life, there emerges in endlessly spare and accessory parts for important living products. Below we list main application area for ten kinds of
valve.
1. valve for petroleum device
1》oil refining equipment The most required in oil refining equipment is the pipe
valve, which mainly includes brake valve, stop valve, check valve, safe valve, ball valve, butterfly valve and drain valve. There in, the brake valve accounts for 80% of the total valve, (the valve account for 3% to 5% of total device investment).
2》chemical fiber device Chemical fiber product mainly includes three types: dacron, acrylic and vinylon. The most necessary of it is valve includes ball valve, jacket valve(jacket ball valve, jacket brake valve, jacket stop valve).
3》propylene sunny device The usually necessary in this device is mainly the brake valve, stop valve, check valve, ball valve, drain valve, needle valve and plug valve. Therein the brake valve accounts for 75% of total valves.
4》synthetic ammonia installation
Since synthesis ammonia is different with the purification method, its technological process as well as the valve technology function are different, too. Currently, The mianly used in synthetic ammonia installation are brake valve, stop valve, check valve, drain valve, butterfly valve, ball valve, membrane valve, control valve, needle valve, safety valve and high & low temperature valve.
2.hydropower station application valve: Our country’ s hydropower station construction now develops into the enlargement. Thus it requires heavy calibre and high pressure safe valve, stop valve, brake valve, butterfly valve, emergency block valve, flow control valve and spherical sealed instrument cut-off valve(according to the National Tenth Five Year Plan, besides Inner Mongolia Province and Gui Zhou Province, both of which still can build power unit with 2 billion kilowatt, while other province and city only can build the power unit over 3 billion).
3.metallurgy application valve: In the metallurgy industry, the mainly necessary in the aluminium oxide action are abrasive resistant slurry valve(stop valve), adjusting drain valve. And the most used in steel-making industry are metallic seal ball valve, butterfly valve, oxidation ball valve, stop valve and four-way reversing valve.
4.sea application valve: following the development of offshore oilfield exploitation, the valves required for sea exploitation are also gradually increased.
5. The food & medicine application valve: The most needed in this line are stainless ball valve, non-toxic all plastic ball valve and butterfly valve. Among ten kinds valve products, the demand of the general valve is in majority such as instrument valve, needle valve, needle stop valve, brake valve, stop valve, check valve, ball valve and butterfly valve.
6. village, city buildings application valve: City buildings usually take the low temperature valve. Currently it develops toward the environment friendly & energy-saving type. The environment friendly rubber valve, balance valve & center line-type butterfly valve and metallic seal butterfly valve is now gradually replaced by the low temperature iron brake valve. The required of the city buildings are balance valve, soft sealing brake valve, butterfly valve and so on.
7.Village & city heat supply valve: It requires a lot of metallic seal butterfly valve, level balance valve and direct burial ball valve in the city heat supply system, because these valve can solve the hydraulic imbalance problem in longitudinal and transverse pipe and realize the energy conservation & heat supply balance.
8. Environmental application valve: in water supply system of environmental system, we mainly use center line-type butterfly valve, soft seal brake valve, ball valve, vent valve(using to exclude the pipe air). The mainly used are the soft seal brake valve & butterfly valve in the sewage disposal system.
9. Fuel gas valve: the city gas accounts for 22% of the total gas market. There are big demand of valves and valve types are various. It mainly needs the ball valve, plug valve, reducing valve and safe valve.
10.pipeline application valve: The majority valves used in the pipeline are forged steel three body full bore ball valve, anti sulfur flat gate valve, safe valve and stop valve.
