Valve technology development trends in 2010

Thread Content

Generally speaking, the price of valves in my country is relatively stable. Although it rises and falls slightly every year, the amplitude is very small. What are the outstanding changes in the development of valve technology in 2010? The editor has compiled three points. 　　1. People-oriented, establish a humanized product design concept. Usually, what we mainly consider in product design are its material, structure, mechanical strength, working performance, service life and other factors. When evaluating the quality of valves, these indicators are generally used. With the development of the times and the progress of society, people-oriented ideas have penetrated into all areas of social life. We can clearly feel this change from housing, cars, computers, mobile phones, clothing and various public facilities. They consider the feelings of consumers in every detail from safety, comfort, energy saving, environmental protection, novelty, beauty and many other aspects, reflecting their care for people. Obviously, humanized design should not be limited to daily consumer goods. As a large-scale and wide-ranging mechanical product, valves are widely used in industry, agriculture, national defense and are closely related to people's daily work and life. They cannot always be limited to traditional design concepts and design methods, but should open up new ideas and inject new concepts. 　　When we analyze advanced foreign products, in addition to various technical performance indicators, we will pay attention to its beautiful shape, exquisite structure, clean inner cavity and exquisite details. For example, in order to prevent secondary pollution, even the drain valve does not use asbestos-containing sealing packing and gaskets. Another example is that in order to prevent the operator's hands from being scratched, the ends of the flange connecting bolts are processed into curved surfaces, etc. These differences in specific details should trigger us to think more deeply.: Why does it do this? How could it have thought of doing this? The conclusion must be attributed to the humanized design concept. Understanding it from this level will make our product design no longer stay in the simple first stage, but from the perspective of ergonomics, from the perspective of safety, reliability, energy saving, environmental protection, clean production, comfortable and convenient operation, easy disassembly and maintenance, etc., giving the traditional product of valves a new concept and image to form its own characteristics. 　　2. Pay attention to the progress of material science and apply new materials, new technologies and new processes to valve products in a timely manner. With the advancement of technology, there are an increasing number of high-parameter and complex working conditions such as high temperature, high pressure, cryogenics, high vacuum, strong corrosion, radioactivity, highly toxic, flammable and explosive in industrial production, thus affecting the safety of valve use. Higher and more stringent requirements have been put forward in terms of performance, functional reliability and service life. Therefore, the development of various valves suitable for high-parameter working conditions has naturally become a common concern of the valve manufacturing industry, engineering design departments and users. The main technical obstacle to solving the problem is often material. Materials science is considered to be one of the most promising subjects in the new century. In recent years, many new high-performance materials have emerged, such as various nanomaterials, superconducting materials, functional materials, organic synthesis and polymer materials, inorganic non-metallic materials and various composite materials. At the same time, many new processes and new technology equipment for molding and surface treatment such as casting, welding, spray welding, spray coating, composite, and sintering have appeared. Paying close attention to the information, trends and results of materials engineering research and development, and applying them to valve products in a timely manner is an important technical way to develop high-performance and high-parameter valves. It is particularly worth mentioning that inorganic non-metallic materials represented by industrial ceramics often achieve good results when used in temperature-resistant, corrosion-resistant and erosion-resistant valve parts. 　　3. Integrating information technology and artificial intelligence technology into valves to achieve integration is a new way of technological innovation. In the current era, information technology is developing rapidly, and informatization and intelligence are constantly changing the face of industrial and agricultural production and people's social life. Valves are the terminal actuators that control fluid movement in pipelines. If modern computing technology, sensing technology, network and remote control technology, and intelligent technology can be implanted into valve products, it will give valves a new concept, resulting in a completely new structure and working mechanism that is completely different from the original products, and achieve a true upgrade of valve products. 　　In recent years, this aspect has begun to take shape in regulating valves, safety valves, pressure reducing valves, traps and other products. For example, spring-type safety valves are currently the most widely used type of safety valve. However, as production equipment becomes larger and more parameterized, it is difficult for this type of safety valve to meet production requirements in terms of structural size and reliability. If a pressure sensing element is installed inside the safety valve to control the rapid opening and closing of the valve, the safety valve will be a completely new model. Another example is that there are currently many types of traps, and their working principles all use the differences in temperature, density, and flow rate between steam and condensed water to open and close the valve through complex mechanisms to complete the function of blocking air and draining water. A new type of trap integrates components that can identify gas and liquid with the valve to control the opening and closing of the valve. New traps designed according to this idea have been reported abroad. Source: http://www.tvtvalve.com/blog/post/20.html
