Valve product calls for new concepts and new image

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 in housing, automobiles, computers, mobile phones, clothing, and various public facilities. From the aspects of safety, comfort, energy saving, environmental protection, novelty, and aesthetics, they carefully consider the feelings of consumers in every detail and show their love for people.

Obviously, humanized design should not be confined to the category of daily consumer goods. Valves, as a wide range of mechanical products that are widely used in industry, agriculture, national defense, and are closely related to people’s daily work lives, cannot be always Contrary to traditional design concepts and design methods, new ideas should be developed and new ideas should be infused.

When we analyze foreign advanced products, in addition to the various technical performance indicators, they will notice its beautiful appearance, compact structure, clean inner cavity and elegant details. For example, in order to prevent secondary pollution, even aseptic valves do not use asbestos-containing sealing packings and gaskets. Another example is to avoid the operator's hand being scratched, the flanges of the connecting bolts are machined into arcs, etc. The difference in these specific details should lead us to consider more deeply: Why does it do this? How could it think of doing this? The conclusion can not be attributed to the design concept of humanization. Understanding from this level will make our product design no longer remain in the simple first stage, but from the perspective of ergonomics, from a more secure, reliable, Energy-saving, environmental protection, clean production, comfortable and convenient operation, easy to disassemble and repair, and many other aspects to study and think, give the valve this traditional product with a new concept and image, to form their own characteristics.

Pay attention to the progress of materials science and apply new materials, new technologies and new processes to valve products in time. With the advancement of technology, high temperature, high pressure, cryogenic, high vacuum, strong corrosion, radioactive, highly toxic, flammable and explosive in industrial production. The increasing number of contour parameters and complex conditions have imposed higher and stricter requirements on the safety of valves, reliability of functions, and service life. Therefore, it is natural to develop various types of valves suitable for high-parameter operating conditions. Become a common concern of valve manufacturing, engineering design departments and users, and the main technical obstacles to solving problems are often material.

Material science is considered as one of the most promising disciplines 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, and inorganic non-metallic materials. A variety of composite materials, etc., at the same time there are many castings, welding, spray welding, spraying, compounding, sintering and other molding and surface treatment of new processes and new technology and equipment. Pay close attention to the information, trends and achievements of material engineering R&D, and apply them to valve products in time, which 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, are often used for valve parts that are resistant to temperature, corrosion, erosion and erosion, and often achieve good results.

Integrating information technology and artificial intelligence into valves to achieve integration is a new era of technological innovation. The era of rapid development of information technology, information and intelligence are constantly changing the appearance of industrial and agricultural production and people's social life. As a terminal actuator for controlling the movement of fluids in pipelines, valves can embed modern computing technology, sensing technology, network and remote control technologies, and smart technologies into valve products, giving valves new concepts, resulting in complete Different from the original structure and working mechanism of the original product, the real upgrading of the valve product is realized. In this regard, in recent years, regulators, safety valves, pressure reducing valves, steam traps and other products have taken initial notice. For example, the spring-loaded safety valve is the most widely used type of safety valve, but with the large-scale and high-parameterization of production equipment, this type of safety valve is difficult to meet the production requirements in terms of structure size and reliability. The safety valve will be a completely new model when the safety valve is equipped with a quick opening and closing of the pressure sensing element control valve. Another example is that there are many types of traps. Their working principle is to use the difference in temperature, density, and flow rate of steam and condensate, and to open and close the valve through a complicated mechanism to complete the function of water-blocking and drainage. A new type of trap is to combine the components that can recognize the 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.
