Valves are widely used in various areas of people's livelihood, as to adapt to different requirements of working conditions, and therefore the number of its great variety. China's huge manufacturing valves, valve manufacturer of thousands, all over the country, China has become a global production and market demand valve one of the countries largest. However, the valve industry in China are mostly small and medium-sized, mixed, the annual output value exceeding 10 billion yuan less than, even compared to other machinery industry in terms of equipment or skill level there is also a large gap between the truly independent research and development unit of the capacity of high-end products rarely, so in the large-scale petrochemical, nuclear power, oil and gas long-distance pipeline projects and other major lines, the matching or the valve is mainly imported.
The current valve enterprises attach great importance to the development of new products. It should be noted that the development of China's valve industry today, although still with the international advanced level in the gap, but has gone beyond simply copy the absorption phase. To seek ways to further develop the technology should be advanced in the analysis of products from abroad at the same time, from a deeper sense of the development trend of valve technology and product development towards a comprehensive analysis and thinking, with independent intellectual property rights to develop new products .
First, people-oriented and establish a user-friendly product design concepts
We are in the product design is usually the main consideration is the material, structure, mechanical strength, work performance, life and other factors in evaluating the merits and demerits of the valve, the general is the use of these indicators. With the development and social progress, people-oriented ideas have penetrated into all fields of social life, from housing, cars, computers, cell phones, clothing and a variety of public facilities can clearly feel this change, them from the safe, comfortable, energy-saving, environmental protection, new, beautiful, and many other aspects of every detail in both the consumer nuanced feelings, reflect on the person's care. Obviously, the design of humanity should not be limited to the scope of daily consumer goods, valves, as a wide amount of different departments, are widely used in industry, agriculture, national defense and to work with people day-to-day life is closely related to the mechanical products, nor the total is limited to the traditional design concepts and design methods, and should explore new ideas and inject new ideas.
We analyze the foreign advanced products in time, in addition to the technical performance indicators, the city noted that its beautiful shape, compact structure, cavity clean, elegant details. For example, in order to prevent secondary pollution, even the use of sewage is not Valve asbestos packing and gasket sealing. Another example is in order to avoid the operator's hand was cut, flange bolt end connections are processed into Globoidal so specific details of these differences, should provoke us to deeper thinking: why does it want to do this? Think of how to do it? Conclusions can not boil down to the design philosophy of human nature to get up from this level of understanding, so that our products will no longer remain in the simple design of the first stage, but from the perspective of the man-machine engineering, from the more secure, reliable, energy saving, environmental protection, clean production, operating comfort and convenience, ease of disassembly and maintenance to study many aspects of thinking, given the traditional valve products to the new concept and image, form their own characteristics.
Second, concern about the progress of materials science, new materials, new technology will process the timely application of new products onto the valve
With advances in technology, industrial production, high temperature, high pressure, cryogenic, high vacuum, strong corrosive, radioactive, toxic, flammable and explosive parameters such as the increasing number of complex conditions, thus the use of safety valve, functional reliability, as well as aspects of life such as a higher and more stringent requirements, so development work to adapt to the high status of the various parameters of the valve, the valve manufacturing sector has become the natural, engineering departments and users on issues of common concern, and The main technical problem-solving obstacles, often on the material.
Materials science are considered the most promising new century, one of the subject, in recent years, many new high-performance materials, such as nano-materials, superconducting materials, functional materials, organic synthesis and polymer materials, inorganic non-metallic materials and a variety of composite materials, etc. At the same time, a number of casting, welding, welding, painting, composites, sintering, such as shape and surface treatment of new technology and new technology and equipment. Pay close attention to materials engineering research and development information, trends and results, the timely application of their products onto the valve, is to develop high-performance valves high parameters of an important means of technology. Particularly worth mentioning is that the representatives of industrial ceramics for inorganic non-metallic materials for use in temperature-resistant corrosion-resistant valves on erosion, and often get good results.
Third, information technology, artificial intelligence technology into the valve, to achieve integration, technological innovation is a new way
The current era, the rapid development of information technology, information and intelligence is constantly changing the industrial and agricultural production and people's social life. Pipeline valve as the control fluid movement in the executive body of the terminal, it would be of modern computing technology, sensor technology, networking and remote control technology, and intelligence technology products to implant the valve, the valve will be given to the concept of a new , resulting in completely different from the original products of the new structure and working mechanism of valve products to achieve real upgrading. In this regard in recent years in regulating valve, safety valve, relief valve, steam trap and other products have shown initial signs of a clue. For example, spring-loaded safety valve is the most widely used as a safety valve, but with the large-scale production facilities and high-parameter, and this type of safety valve in the structure of the size and reliability are difficult to meet the requirements of production, if built-in safety valve for pressure control valves, sensors rapid hoist, the safety valve will be a new model. Another example is a lot of the current trap type, and its working principle is the use of steam and condensation of water temperature, density, velocity differences in the body through the complex realization of the gate valve to complete the drainage gas-barrier function. A new type of trap is able to identify the components of gas-liquid form and one valve to control the gate valve, in accordance with this line of thinking of new trap design has been reported abroad.
Fourth, the expansion of horizons, the concept of the establishment of major projects, familiar with the technology of large-scale sets of device characteristics, the development of high-tech high value-added products of high-end valve
Valves for industrial production of devices supporting equipment, the process to guarantee the normal operation of the safety play an important role. Development of new valve products which are not closely associated from the production facilities and production processes. The rapid development in science and technology today, the industrial production of new products, new processes, new processes, new devices are emerging, thus supporting the valve functions, structure and materials accordingly put new demands. Development for specific industries, specific process "tailored" for various kinds of special valves, new product development is an important "themes", but also of major technologies and equipment for pressing domestic needs, such as nuclear power valves, long-distance oil and gas pipeline valves, slurry valves, such as coal chemical industry. To this end, the concept of large projects have, only got a few design parameters, on the valve of the valve does not work, to the whole project and complete sets of equipment have a comprehensive concept of integrity, understanding of its production process, production environment, operating conditions and the related technical specifications and so on, on this basis to the idea, development, design engineering required to adapt to unique products, as a writer only life can create the same good work.
Valve category many different, ever-changing market demand, the valve manufacturer's production scale and technical level have been mixed, valve products in the overall trends and the development of technical means has much in common with. Valves in light of its own if the conditions of enterprises, science and technology along the way to determine their own new product development objectives, will be less detours, the valve industry in China continued to promote healthy development. ball valve Trunnion Mounted Ball Valve Floating Ball Valve Top Entry Ball Valve Three way ball valve V Type Ball Valve
