Gap of the world valve expansion of mechanical equipment manufacturing requirements rise in the process of our valve localization bumpy forward

With the development of society and the progress of The Times, human-centered ideas have long penetrated into all walks of life in the society. This change can be obviously felt in houses, vehicles, computers, mobile phones, clothing and various public facilities. 100X remote control floating ball valve from safety, comfortable, environmental protection, energy saving, environmental protection, novelty, beautiful and generous in every detail of the above carefully consider the customer experience, reflecting the care of people.
Obviously, intimate design is not limited to the range of consumer goods, valve as a wide range of quantities, widely used in industrial production, farming, and everyone’s daily work and life of mechanical equipment products, also can not be due to the traditional design concept and design theory, and should expand a new idea, diaphragm remote control floating ball valve injection fresh core concept.
Traditionally used globe valves have many shortcomings, such as: water seepage, corrosion, poor tightness, etc. Standard light valve introduced overseas high-tech plastic technology will be the traditional globe valve independent innovation, production and manufacturing of fire gate valve. Fire gate valve to replace the traditional globe valve products, the use of the overall package molded into the deformation compensation to achieve very good sealing performance, and then solve the shortage of traditional globe valve quantity.
With the development of science and technology, various domestic industries have kept up with the international pace, hard to reduce the gap between a part of the industry and foreign industries, the valve industry is also the same, in recent years, Chinese valves in China with each other big price competition, and no improvement, resulting in a significant expansion of the gap between Chinese valves and foreign valves.
The gap between countries in the world to expand the mechanical equipment manufacturing requirements rise
Refrigeration industry, especially small accessories, long-term criticism refers to the role of standardization and innovation. The gap between Chinese valve industry and foreign valve industry is relatively obvious at present stage, there are four comprehensive gaps: first, the gap in independent innovation capability; Second, the gap in the production process; Third, the gap in quality control and equipment; Fourth, the gap in process optimization. Also let us see their own shortcomings, so as to find the gap and the nature of the problem, and then improve and enhance.
Sales market prospects of refrigerating accessories electric valve are promising
Industry related personnel revealed that the valve class in the industrial production link, most used to manipulate a variety of fluid driving and total flow, such as water, oil, chemical liquids, according to the parameter values of temperature, pressure and data flow. The common pressure regulating valves in processing plants include pressure reducing valves, pneumatic constant temperature valves, relay constant temperature system software, proportional pressure regulating valve constant temperature system software, environmental temperature regulating valves and other different types. In the use of various automatic valves, attention should be paid to the type of internal combustion engine, standard precision, pressure valve quality, pressure drop, total flow and structure, equipment failure rate, manufacturers personal credit and after-sales service and other factors, in order to achieve cost-effective effect.
Mechanical equipment manufacturing valve market demand rise
The product itself, because the electric regulating valve has very easy installation, low failure rate, and in line with the advantages of the industry automation technology requirements, is worth choosing businesses. Because of the use of the general traditional pneumatic valve, it is inevitable to have pipelines, relays and air compressors, and electric regulating valve to motor driven, simple and convenient assembly, and electric regulating valve assembly with processing plant original automatic control distribution line can be, can save other costs. In addition, the motor drive method is more stable opening and closing, no instantaneous impact force is too large defects, equipment failure rate can be greatly reduced.
With the continuous progress of domestic science and technology, electric gate valve is also developing to high added value, high main parameters, strong corrosion resistance and high service life.
Electric valve market demand rises
In recent years, with the rapid development of electromechanical integration, electric valves, an important machine products ushered in the industry. Great market demand for electric valves put forward higher requirements.
In the operation efficiency and energy saving level, the application of automatic control valve is an indispensable link, traditional industry common hand valve, pneumatic valve, in the use of cost and efficiency of the father is not as good as the electric control valve. Media said electric control valve into valve market mainstream products.
With the continuous progress of domestic science and technology, electric gate valve is also developing to high added value, high main parameters, strong corrosion resistance and high service life.
In the process of domestic production of the valve, the valve industry has developed rapidly in recent years, with many factors such as raw materials and human costs, product import and market share have developed continuously, and the main production place and main product market have been formed gradually. But in our country there are many companies of the valve plants, small scale, lack of competitive ability, and the company’s low market concentration, cannot cause visibility in the global valve market, hinders the healthy and orderly development of the valve industry to a certain extent.
In our country in the process of localization of the valve bumpy forward
Generally speaking, the way of localization of valves appears extremely difficult. At the present stage, whether in the Chinese market at the level of national support policy, or at the current level of technology, the development of the valve is not beneficial. As basic parts have become a weak point to restrain the development of China’s manufacturing industry, China will continue to increase the scope of domestic production of weapons and equipment parts during the 12th Five-Year Plan period.
According to statistics, the important problems of valve domestication in our country at present have the following aspects:
According to the statistics of the water pump industry, the distribution of product research and development funds in the water pump industry accounts for less than 2% of the main business income of enterprise managers. Compared with foreign enterprises, the distribution of development funds in the whole industry is very small. Relevant statistics show that the annual research and development expenditure of Chinese water pump industry is less than that of an overseas enterprise. Research fees, insufficient investment in product research and development, has become an important factor to restrain the independent development of valve companies.
In our machinery and equipment manufacturing industry, the digestion of innovation technology is slow, most enterprises are not strong in technical innovation ability, 57% of the key machinery and equipment product technology sources with the help of introduction. At present, the vast majority of products in the domestic pump production and manufacturing industry have basically completed independent production and processing, but domestic companies are more than responsible for the low-level production and processing stage of products, practical depth and breadth to be improved. For example, the nuclear grade pump products in the mechanical equipment of nuclear power plant and the boiler feed water pump core package products in the 10,000 kilowatt supercritical extraction and the ultra-supercritical thermal power generation machinery and equipment have been gradually localized. Most of their key technologies still need to be imported.
Customers are less inclined to buy from China. Although Chinese products in the technical indicators to achieve the same level as foreign, but some customers are still willing to buy domestic and foreign technical equipment, prompting the first set of major domestic technical equipment pump products into the market difficulty. Although many domestic pump products have a certain level of technology, but some application units are still reluctant to apply for lack of operational performance.
Industry generic technology scientific research is lacking. Because of the reform, some scientific research institutes that provide services to the industry have become companies with their own duties, and the structural characteristics and work focus have undergone great changes. Its technical promotion role in the industry is weakening day by day, new technology application, new process research and development rate is slow, design scheme, processing technology, materials and manufacturing and other specifications are difficult to connect with foreign countries.
Our country’s valve sales market birthday cake is big, but the industry competition is also very fierce. With the acceleration of the rejuvenation of high-end equipment manufacturing in the current policy, the development of universal basic manufacturing industry will be further emphasized, the process of valve localization will be accelerated gradually. But Chinese valve processing manufacturing industry level and the comparison of international leading level still has a certain gap, many high parameters, ultra-high pressure and high temperature, high pound class of important valve original has been dependent on imports. For the better development of Chinese valve industry, it is necessary to optimize and optimize the industrial distribution, not only to fully utilize the advantages of the traditional valve industry chain, but also to vigorously promote professional knowledge, technology-intensive industries and new industries, to promote pressure regulating valve, plug valve, regulating valve industry chain upgrading.
