Plant water pump market will be more tend to be more professional

Since the 80 s, China began to organize backbone enterprises of similar products imported valve design, technology and other advanced technology and processing equipment, make our country power station pump manufacturing technology and product quality has been rapidly improved. At present, the domestic valve production backbone enterprises can according to ISO international standards, the German DIN standards, AWWA standard American international standard design and manufacture all kinds of valves, such as part of the manufacturer's products reached the international advanced level. Although the overall level of valve industry over the past few years have a larger increase, but also the quality is not stable, such as run, run, drip, leak phenomenon often appears in the domestic valves. Valves, in addition, the supporting capacity is also compared with the developed countries there is still a big gap between.

Valve is low profit products, the market competition is fierce. Valve market distribution, mainly on the basis of the construction of the project, the valve is the biggest user department of department of petrochemical industry, electric power, metallurgy, chemical industry and urban construction department. Petrochemical industry the main application of API standard gate valve, globe 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; The chemical industry mainly adopts stainless steel gate valve, globe valve, check valve; Metallurgical industry mainly adopts low voltage large diameter butterfly valve, oxygen cut-off valve and ball valve; 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; The food industry mainly adopts stainless steel ball valve and so on. Valves used in water treatment industry, mainly in low-pressure valve products, such as butterfly valve, gate valve, check valve. It is understood that the valve of a certain scale enterprises on the market at present more than 2000, most distribution in jiangsu and zhejiang provinces and the central plains area. Due to the product technology content requirements are relatively low, therefore, competition is more intense.

On the one hand, the valve products in our country is faced with good opportunities for development. 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, valve products should be based on equipment application domain changes to change its properties and corresponding parameters. Urban construction system generally USES a large number of low pressure valves, and to the development of environmental protection and energy-saving, that is used by the 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. 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.

Power plant construction toward 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. 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 more and more big.
