Information
Since the 1980s, China has begun to organize key enterprises to introduce advanced technologies and processing equipment for the design and technology of similar products of foreign valves, so that the quality of valve manufacturing technology and products in China has been rapidly improved. At present, domestic valve production backbone enterprises have been able to design and manufacture various valves according to ISO international standards, DIN German standards, AWWA American standards and other international standards. Some manufacturers' products have reached the international advanced level. Although the overall level of the valve industry has been greatly improved in the past few years, the quality is not stable enough. For example, running, taking, dripping and leaking phenomena often appear in domestic valves. In addition, China's valve supporting capacity is still a certain gap compared with developed countries.
Valves are products with low profit margins and the market is highly competitive. The distribution of the valve market is mainly based on the construction of engineering projects. The largest users of valves are petrochemical industry, power sector, metallurgical department, chemical industry and urban construction department. The petrochemical industry mainly uses API standard gate valves, globe valves and check valves; the power sector mainly uses high-temperature pressure gate valves, globe valves, check valves and safety valves for power stations and some low-pressure butterfly valves and gate valves for water supply and drainage valves; Stainless steel gate valve, globe valve, check valve; metallurgical industry mainly uses low pressure large diameter butterfly valve, oxygen shutoff valve and oxygen ball valve; urban construction department mainly uses low pressure valve, such as urban tap water pipeline mainly adopts large diameter gate valve, building construction mainly adopts middle line Butterfly valve, urban heating mainly uses metal sealing butterfly valve; oil pipeline mainly uses flat gate valve and ball valve; pharmaceutical industry mainly uses stainless steel ball valve; food industry mainly uses stainless steel ball valve. Valves are used in large quantities in the water treatment industry, mainly based on low-pressure valve products, such as butterfly valves, gate valves, and check valves. It is understood that there are more than 2,000 valve companies with a certain scale on the market, most of which are distributed in Jiangsu, Zhejiang and Central Plains. Competition is more intense due to the relatively low technical content requirements of the products.
On the one hand, China's valve products are facing good development opportunities. With the development of oil development to inland oilfields and offshore oil fields, and the development of power industry from thermal power of less than 300,000 kilowatts to thermal power and hydropower and nuclear power of more than 300,000 kilowatts, valve products should also change their performance according to changes in equipment application fields. parameter. Urban construction systems generally use a large number of low-pressure valves, and the development of environmentally friendly and energy-saving, that is, the low-pressure iron gate valve used in the past has gradually turned to environmentally friendly rubber plate valves, balancing valves, metal sealing butterfly valves and mid-line sealing butterfly valves. Oil and gas transmission projects are developing in the direction of pipelines, which in turn requires a large number of slab gate valves and ball valves. The other side of energy development is energy conservation, so from the perspective of energy conservation, steam traps should be developed and developed to subcritical and supercritical high parameters.
The construction of the power station is going to be large-scale, so it is necessary to use large-diameter and high-pressure safety valves and pressure reducing valves, as well as fast opening and closing valves. For the needs of complete sets of projects, the supply of valves has evolved from a single variety to multiple varieties and multiple specifications. The valve required for an engineering project is increasingly being provided by a valve manufacturer.
