     Valve is widely used, because the different conditions of the various

engineering needs, so the valve family of over 200 species and over 3000

specifications. Valve manufacturing in Chin a is very large, valve manufacturers

throughout the country, China has become one of the largest global valve production

and market demand. China s valve industry, mostly small and medium-sized

enterprises, only a dozen of the annual output value exceeding 100 million yuan, hydraulic hose crimping machine

compared with the international valve industry, there is a big gap in terms of

equipment, or technical level, a truly independent research and development ability

valve manufacturers of end products rarely, and thus in large petrochemical,

nuclear, oil & gas transmission pipeline and other major projects, engineering npt pipe fittings

supporting the valve dependent on imports, only Neway, SUFA Chaoda Zigong High

Pressure f ew R & D capability strengths enterprises to participate in the

competition.

    More valve companies recognize that the valve R & D capabilities of the new

products and technologies directly affect the competitiveness of enterprises. Valve

with the continuous development according to the company s technical team, analysis

of home and abroad advanced product structure, efforts to develop new products with

independent intellectual property rights.

First, establish a humane concept of product design, fine refinement

    Usually the main consideration in product design elements of the material,

structure, mechanical strength, performance, service life, the general also use hydraulic tube fittings

these indicators in the evaluation of the valve of the pros and cons. With the

development, people-oriented ideas have penetrated into various fields of social

life in every detail, nuanced account of the user s feelings, reflect on care.

Valve, as a large, widely used in industry, agriculture, national defense and

people s daily work and life are closely related to mechanical products, can not

always confined to the traditional design concepts and design methods, but should

explore new ideas, inject new ideas. Advanced foreign products in addition to the

technical performance indicators, will be noted that its beautiful shape, compact

structure, the cavity is clean and elegant details. For example, in order to prevent

secondary pollution, sewage pumps do not use asbestos packing and gasket sealing; in

order to avoid the operator hands are scratched, and the ends of the flange

connecting bolts are proces sed into arc, product design no longer remain in its

infancy, but from an ergonomic point of view, thinking to delve into many aspects

more secure, reliable, energy saving, environmental protection, clean production,

operating comfort and convenience, easy disassembly and maintenance, to give the

valve the traditional products to the concept and image of humanity.

Second, new materials, new technologies and new technology application in valve

products

    As technology advances, the industrial production of high temperature, high

pressure, low temperature, high vacuum, high corrosion, high wear, radioactive,

toxic, flammable and explosive high-parameter complex conditions an increasing

number, in order to use the safety of the valve, proposed more stringent

requirements for reliability and service life of the functions developed to adapt to

various types of valves in high-parameter conditions, naturally, a valve

manufacturing, engineering, design department and user issues of common concern,

materials, material is the primary technical barriers.

    Foreign valve durability, the most critical is the leading of materials and

material processes, in recent years, many new high-performance materials, while

there are a lot of casting, welding, spray, spraying, composite, sintering the

molding and surface treatment of the new technology equipment and new technologies.

Attention to materials science, information, and timely application to the valve, is

an important method for developing high-performance parameter of the valve. For

example, industrial ceramics, inorganic non-metallic materials for temperature

corrosion resistance, erosion of the valve, and has achiev ed very good results.

Third, information technology, artificial intelligence technology integration

    IT is the rapid development of intelligent information technology is changing

the face of industrial and agricultural production and living. Valve to control

fluid movement in the pipeline terminal executing agency, if the ability to modern

computing technology, sensor technology, network and remote control technology and

intelligent technology to implant valve product, produce completely different from

the original products of the new structure and The working mechanism of a real

upgrade of the valve product. In this regard in recent years, the regulating valve,

safety valve, pressure reducing valves, steam traps and other products has shown

signs.

Familiar with the characteristics of complete sets of equipment, development of

high-tech specialty valves

    Valve device as industrial production equipment, the normal operation of the

guarantee the safety of the process plays a very important role. Development of new

valve products can not be separated from the closely associated production equipment

and production processes. The rapid development of technology today, the industrial

production of new products, new processes, new processes, new devices are emerging,

thus supporting the valve function, structure, materials accordingly put forward new

demands. All kinds of special valves, development of specific industries, specific

process "tailored" important "themes" of the new product development, the urgent

need of major technology and equipment, such as nuclear power valves, oil and gas

long-distance pipeline valves coal chemical slurry valves. To this end, the concept

of a major project, alone to get a few design parameters, the valve on the valve

does not work, the whole project and complete sets of equipment, a complete concept

to understand its production process, production environment operating conditions

and the relevant technical specifications, etc., on this basis can the idea of ​​

development, designed to adapt to project needs a special valve.

    The valve manufacturer s production scale and skill levels, valve products in

the overall trends and the development of technical means it has much in common. If

the valve business of its own conditions to determine their own new product

development goals along the scientific technical means, detours will promote

sustained and healthy development of China s valve industry
