The

origin and application of ancient valves

The origin of ancient valves

China:
The Valve originated in China and dates back to more than two thousand years ago. In ancient China, people began to use valves to control the flow of fluids.
The earliest forms of valves were probably bamboo and cork valves, simple devices used in water delivery lines to prevent water leakage.
With the development of valve technology over time, people began to use locks in irrigation canals, which not only regulated the flow of water, but also played a role in flood control.
In terms of smelting technology, ancient China also used plate check valves, which can prevent the backflow of fluid and ensure the smooth progress of the smelting process.

Ancient Egypt and Rome:
The ancient Egyptians and Romans also used similar devices to control the flow of water. They use simple plug, gate and lever principles to achieve fluid control.
The ancient Romans developed quite complex water systems for crop irrigation, which used valve devices such as plug valves and plunger valves.

Application of ancient valves
Agricultural irrigation:
In ancient times, valves were widely used in agricultural irrigation systems. By adjusting the opening of the valve, the flow and direction of the irrigation water can be controlled to meet the irrigation needs of different crops.
Salt production:
In ancient China, valves were also used in the production of salt. For example, in the process of well salt mining, people use bamboo pipes and plate check valves to extract salt water. This valve device effectively prevents the leakage and backflow of salt water.
Water conservancy Project:
Ancient water conservancy projects can not be separated from the application of valves. For example, sluice, as an important water conservancy project facility, regulates the flow and direction of water flow by opening and closing to ensure the safety and efficiency of water conservancy projects.

Valve development during the Industrial Revolution

Technological innovation and demand growth

With the advent of the Industrial Revolution, new technologies such as steam engines and hydroelectric power generation continue to emerge, and the demand for fluid control is also growing. During this period, the design and production of valves gradually became specialized to meet the needs of new industrial applications.

The revolution of production process
Mechanized production: The industrial revolution has promoted the development of machinery manufacturing, and valve manufacturing has gradually shifted from manual production to mechanized production. The introduction of machine tools, punches and other mechanical equipment has achieved large-scale and standardized production of valve manufacturing, and greatly improved production efficiency.
Quality control: Mechanized production not only improves production efficiency, but also ensures the consistency and quality stability of valve products through standardized production processes. This provides a strong guarantee for the wide application of the valve in the industrial field.

The expansion of application fields

The steam engine and the thermal system: In the Industrial Revolution, the steam engine became the main source of power. The valve plays a key role in the operation of the steam engine, which is used to control the flow and pressure of the steam to ensure the stable operation of the steam engine.
Hydropower: With the development of hydropower technology, valves have also been widely used in hydroelectric power generation systems. They are used to regulate water flow, control water pressure, and protect equipment from impact loads such as water hammers.
Marine and chemical industry: Valves are also widely used in Marine and chemical industry. On ships, valves are used to control the flow of fluids such as fuel oil and cooling water; In the chemical industry, valves are used to control the flow and reaction process of various chemical media.

The development of modern valves

Technological innovation to promote the development of valves
Intelligent trend: With the rapid development of science and technology, intelligence has become an important development direction of the valve industry. Intelligent valve through the integration of sensors, actuators, controllers and other advanced equipment, to achieve real-time monitoring of the fluid system, automatic regulation and remote control. This technological innovation not only improves the operating efficiency of the valve, but also enhances its safety and reliability. For example, the intelligent valve can automatically adjust the opening of the valve according to preset parameters or real-time condition changes to ensure the stable operation of the fluid system; At the same time, through the Internet of Things technology, users can remotely monitor and manage the valve anytime and anywhere, and understand the operating status of the valve in real time.
New material application: In the valve manufacturing process, the application of new materials also promotes the improvement of valve performance. For example, the use of high-strength, corrosion-resistant materials to manufacture valves can extend the service life of the valve and reduce maintenance costs. In addition, with the improvement of environmental awareness, more and more valve manufacturers have begun to pay attention to the environmental protection of materials, and promote the green development of the valve industry.
