Introduction
Valves play an integral role in our everyday life and industrial production. They are found in a wide range of applications, from household water systems to large-scale infrastructures like the Three Gorges Dam and the Qinshan Nuclear Power Station, and even in space technology such as the Shenzhou series spacecraft and space stations.
The Significance of Valves
In a 1 million kilowatt nuclear power station, the cost of the valves constitutes 5% to 10% of the total investment. Furthermore, the maintenance cost of these valves accounts for half of the station's upkeep expenses. This highlights the critical role valves play in such settings.
Classification of Valves
To assist our customers in understanding valve products, JIANENG VALVE has categorized common valves based on actual site conditions. Some are selected by the manufacturer, and others are used differently under special circumstances.
Main Categories
There are two primary categories:
- Automatic Valves: These valves operate on their own by utilizing the medium's (liquid, gas) inherent capabilities. Examples include control valves and pressure relief valves.
- Drive Valves: These valves are operated manually or through electric, hydraulic, or pneumatic means. Butterfly valves and ball valves fall under this category.
Other Classifications
Valves can also be classified in several other ways:
- By Driving Method: Electric, hydraulic, pneumatic
- By Connection Method: Flange, threaded, welded, clamp, ferrule
- By Purpose: For opening and closing, for adjustment, for distribution, and for other special purposes
- By Nominal Pressure: Vacuum, low-pressure, medium pressure, high-pressure, ultra-high pressure
- By Working Temperature: Normal temperature, high temperature, ultra-high temperature, low temperature, ultra-low temperature
- By Nominal Diameter: Micro, small diameter, medium diameter, large diameter, extra-large diameter
- By Structural Characteristics: Gate type, plug and ball type, rotary opening type, disc type, slide valve type
