Liquid Cooling Butterfly Valve's Structure And Working Principle
water cooling Butterfly Valve acts as a steam barrier and drain in steam heating systems. Choosing the right cooling water Butterfly Valve ensures efficient steam heating equipment operation. To achieve optimal results, a comprehensive understanding of the performance and characteristics of various Butterfly Valve cooling system types is essential.
There are many different types of water cooling Butterfly Valve, each with its own unique performance characteristics. When selecting a Butterfly Valve cooling, first choose the one with the characteristics that guarantee optimal operation of the steam heating equipment, then consider other objective conditions. This way, choosing the cooling Butterfly Valve you need is the correct and effective choice.
cooling water Butterfly Valve must be able to "distinguish" steam and condensate to function as a steam barrier and drain. This "distinguishing" of steam and condensate is based on three principles: density difference, temperature difference, and phase change. Three types of Butterfly Valve data center are therefore manufactured based on these three principles: mechanical, thermostatic, and thermodynamic. 1. Mechanical Type
The mechanical type, also known as the float type, utilizes the density difference between condensate and steam. The condensate level changes cause the float to rise and fall, driving the valve disc to open or close, thereby preventing steam from flowing out. The mechanical type offers low subcooling and is unaffected by fluctuations in operating pressure and temperature. It drains water as soon as it is present, preventing water from accumulating in the heating equipment, ensuring optimal heat exchange efficiency. With a maximum back pressure ratio of 80% and high operating quality, it is ideal for heating equipment in production processes.
Mechanical types include free float, semi-free float, lever float, and inverted bucket.
2. Thermostatic Type
This type of liquid cooling butterfly valve utilizes the temperature difference between steam and condensate to cause deformation or expansion of the temperature-sensing element, driving the valve core to open and close. Thermostatic Liquid Cooling Butterfly Valves offer a relatively high degree of subcooling, typically ranging from 15°C to 40°C. They utilize some of the sensible heat in the condensate, ensuring a constant supply of high-temperature condensate upstream of the valve, preventing steam leakage and significantly reducing energy consumption. They are ideal for steam pipelines, heat tracing lines, small heating equipment, and heating systems with low temperature requirements.
Thermostatic Liquid Cooling Butterfly Valves include diaphragm, bellows, and bimetallic types.
3. Thermodynamic Liquid Cooling Butterfly Valves
This type of Liquid Cooling Butterfly Valves operates based on the phase change principle. The differential pressure across the valve disc is generated by the thermodynamic differences in flow rate and volume of steam and condensate as they pass through it, driving the valve to open and close. Because the operating power of thermodynamic Liquid Cooling Butterfly Valves is steam, steam waste is relatively high. Simple structure, resistant to water hammer, maximum backlash of 50%, noisy, frequent valve operation, and short service life.
Thermodynamic Liquid Cooling Butterfly Valves include thermodynamic (disc), pulse, and orifice types.
