Do You Know the Origin and History of The Valve?(Part 1)
The past and future of the valve(Part 1)
Draw halogen ("Heavenly Creations. For the salty fifth"
The development of the valve is closely related to the development of the industrial production process. In ancient times, people used large stones or trunks to stop the flow of water or change the direction of water flow in order to regulate the flow of water in rivers or streams. As early as the end of the Warring States Period, Li Shu, prefect of Qin Shu County, had dredged salt wells in the Chengdu Plain. Take halogen, take fine bamboo as draw halogen cylinder, halogen tube, the bottom of the cylinder to the valve for opening and closing, a cylinder can draw halogen bucket, well up vertical wooden frame, with a potter's wheel, extract brine to bamboo bucket Empty at one end mounted wooden plunger valve to prevent leakage, child into the well brine to salt the ancients is not very talented!
Ancient Roman complex water system
Several primitive valve types were invented by Egyptian and Greek civilizations for crop irrigation and the like. However, it is generally accepted that the ancient Romans developed rather complex water systems for crop irrigation, using plug and plunger valves and using check valves to prevent water from flowing backwards.
Da Vinci mechanical design manuscripts
During the Renaissance, valves were used in ditches, irrigation projects and other large hydraulics projects designed by artist and inventor Da Vinci, and many of his technical solutions are still in existence. The original is not only know that Leonardo da Vinci is a great painter, did not think he actually had such a great contribution to the valve.
Then Europe because of exercise technology and the development of water conservancy machinery, the valve requirements gradually increased, so to create a copper and aluminum plug valve, the valve before entering the metal.
Watt steam engine model
Valve industry, modern history and industrial revolution in parallel, with the deepening of the industrial revolution in-depth. In 1705 Newcombman invented the first industrial steam engine, putting forward the control requirements for the operation of the steam engine. In 1769, Watt created a steam engine to make the valve officially enter the mechanical industry. Most of the steam engines use plug valves, safety valves, check valves and butterfly valves.
Watt invented the steam engine is the beginning of a large number of applications in the valve industry. From the 18th century to the 19th century, the steam engine was rapidly promoted in the mining, exercise, textile, machinery manufacturing and other industries. The valve number and quality were increasing. He also invented the first controller to regulate the speed, then the flow of fluid control more and more attention. The successive appearance of the valve with a threaded stem and wedge gate valve with a trapezoidal thread valve is a major breakthrough in the development of the valve. The appearance of these two types of valves is not only satisfied with the current industry pressure on the valve and continuously improve the temperature requirements, and initially satisfied with the flow regulation requirements.
【Describe the origin and history of valve】
Do you know the origin and history of the valve?
Broadly speaking, in the Warring States period of thousands of years ago, the ancient people used valves to carry out production operations, it is not for a long time! As a modern pump industry practitioners, a brief review of the origin and history of the valve is also a very meaningful and interesting thing, After reading, will feel as a valve of pride and pride, but also one more responsibility and responsibility for the valve industry in the future.
When it comes to valves, I believe many people are familiar with it. Yes, the use of valves touches every day in our lives. When we open the faucet to drink water or open the fire hydrant to irrigate the farmland, We interact with the valve , Dense pipeline intertwined, behind all the stick with a variety of valves.
From a functional perspective, a valve is a control component in a fluid delivery system that has functions such as cut-off, regulation, diversion, reverse flow prevention, voltage regulation, shunting, or relief pressure relief. Valves can be used to control the flow of various types of fluids, including corrosive media such as air, steam, mud, oils, liquid metals, and radioactive media. The distribution of the valve market is mainly based on the construction of engineering projects. Valves of various industries are widely used, mainly petroleum, petrochemical, chemical, metallurgy, electric power, water conservancy, urban construction, fire protection, machinery, coal, food and others. Valves in the water treatment industry to use a larger, mainly low-pressure valve products, such as ball valve, gate valve, globe valve, check valve, needle valve.
