China's vavle market is getting worse and worse,mainly because there is no innovation.Petrochemical industry the main application of API standard gate valve, globe valve Plug valve, ball valve ,and check valve;Power sector mainly adopts power station with high temperature and pressure gate valve, globe valve, check valve and relief valve, and part of the water supply and drainage valve of low pressure butterfly valve, gate valve;Chemical industry mainly adopts stainless steel gate valve, globe valve, check valve, breathing valve, flame arresters, filters, pipes, sight glasses, etc.Metallurgical industry mainly adopts low voltage large diameter butterfly valve, oxygen cut-off valve and ball valve, valve, breathing valve, flame arrester;Urban construction department mainly adopts low-pressure valve, such as urban tap water pipeline mainly adopts large-diameter gate, building construction mainly USES the center line butterfly valve, city heating mainly adopts metal sealing butterfly valve;Pipeline mainly adopts flat gate valve and ball valve;The pharmaceutical industry mainly adopts stainless steel ball valve, breathing valve valve, flame arrester;Food industry mainly adopts stainless steel ball valve, breathing valve valve, flame arrester, etc.
About valve products market, according to the analysis, in the next period of time the main trend is as follows:
1. As the oil development to the mainland oil fields and the transfer of offshore oil field, as well as the electric power industry from 300000 kw to 300000 kw thermal power under the above of the thermal power and hydropower and nuclear power development, the respiration valve, flame arrester, filters, pipes, sight glasses, and other products should be based on equipment application domain changes to change its properties and corresponding parameters.
2. Urban construction system generally USES a large number of low pressure valves, and to the development of environmental protection and energy-saving, namely by the use of low iron gate toward environmental protection rubber sheet, balance valve, the transition metal sealing butterfly valve and the midline sealing butterfly valve.Oil and gas engineering to develop in the direction of pipelining, it requires a lot of flat gate valve and ball valve.
3. The other side of the energy development is energy saving, so in terms of energy conservation, to develop the steam trap, and high toward the subcritical and supercritical parameter.
4. The construction of the power station to large-scale development, so the need of large diameter and high pressure relief valve and pressure reducing valve, at the same time also need quick opening and closing valves.
5. Package engineering needs, the supply valve by a single species to more varieties and specifications.A project required valve, provided by a valve manufacturer all trend is getting bigger and bigger.
