Valve development history

As a fluid control device, valves play an important role in the development of human industry. The following will introduce the development of the valve.

1. Ancient valves: As early as ancient times, people began to use simple valves to control water flow. Ancient Egyptians and Greeks used wood, stone and other materials to make valves for irrigation, drainage and other purposes. These ancient valves were mainly manually operated and functionally simple, but laid the foundation for the development of later valves.

2. Industrial Revolution period: With the arrival of the industrial revolution, the development of valves has entered a new stage. At the end of the 19th century and the beginning of the 20th century, with the wide application of steam engines, boilers and other mechanical equipment, the demand for valves increased greatly. Engineers began to design and manufacture various types of valves, such as gate valves, globe valves, ball valves, etc., to meet the needs of different industrial fields.

(3) Valve standardization: in the middle of the 20th century, with the improvement of industrialization and the development of international trade, countries began to develop standard specifications for valves in order to facilitate the unification and interoperability of product quality. The design, manufacture, installation and use of various valves have been standardized, improving the reliability and safety of the valves.

4. Automated valves: With the continuous progress of science and technology, automation technology is more and more widely used in the field of valves. Automatic valves can be remotely controlled and automated by electrical, pneumatic, hydraulic and other means, improving production efficiency and safety of the working environment.

5. New materials and new technologies: In recent years, with the continuous emergence of new materials and new technologies, the manufacturing process and performance of valves have been further improved. Superalloy, ceramic materials, plastic materials, etc., are widely used in valve manufacturing, improving the corrosion resistance and wear resistance of the valve. At the same time, advanced CNC machining technology, simulation technology, etc., also provides more possibilities for the design and manufacture of valves.

6. Environmental protection and energy-saving valves: With the improvement of environmental protection and energy-saving awareness, people's requirements for valves are becoming higher and higher. Energy-saving valves, zero leakage valves and other new valves have been widely used to reduce energy consumption and environmental pollution.

In general, valves, as fluid control equipment, have experienced an evolution process from simple to complex, from manual to automated in the course of human industrial development. With the continuous progress of science and technology and the continuous development of industry, the design, manufacturing and application of valves will continue to innovate and improve, providing better support and guarantee for the development of all walks of life.

Valves are used in different fields today.

1. Petrochemical industry: In the petrochemical production process, valves are widely used in crude oil transmission pipelines, refining units, chemical reactors and other equipment. The valve can control the flow of crude oil, natural gas, chemical raw materials and other media to ensure the smooth progress of the production process.

2. Power industry: In thermal power plants, nuclear power plants and other power facilities, valves are used to control the medium flow of boilers, steam turbines, cooling systems, etc., to ensure the normal operation of power equipment.

3. Water treatment industry: In water treatment facilities such as tap water treatment plants and sewage treatment plants, valves are used to control water flow and adjust water pressure to ensure the normal operation of water treatment systems and the stability of water quality.

4. Pharmaceutical industry: In the pharmaceutical production process, the valve is used to control the flow of pharmaceutical raw materials, solvents, preparations and other media to ensure the quality and safety of drug production.

5. Food industry: In the food industry such as food processing plants and beverage production plants, valves are used to control the flow of food raw materials, clean water, steam and other media to ensure the hygiene and quality of food production.

6. Construction industry: In construction projects, valves are used in water supply systems, HVAC systems, fire fighting systems and other facilities to control the distribution and regulation of water flow and air flow to ensure the normal use of buildings.

7. Aerospace field: In aircraft engines, aircraft hydraulic systems and other equipment, valves are used to control the flow of fuel, hydraulic oil, gas and other media to ensure the normal operation of aircraft.

8. Automobile manufacturing industry: In the automotive engine, transmission, brake system and other components, valves are used to control the flow of fuel, lubricating oil, brake fluid and other media to ensure the normal driving and safety of the car.
