The cooling tower is a device that uses water as circulating coolant to absorb heat from a system and discharge it to the atmosphere to reduce water temperature; Its cooling is an evaporative heat dissipation device that uses the principles of evaporative heat dissipation, convective heat transfer and radiant heat transfer to dissipate the waste heat generated in industry or in refrigeration and air conditioning to reduce the water temperature, so as to ensure the normal operation of the system. The device is generally barrel shaped, so it is called a cooling tower. Cooling tower is a comprehensive product of aerodynamics, thermodynamics, fluid science, chemistry, biochemistry, materials science, static and dynamic structural mechanics, processing technology and other disciplines. Water quality is a multivariable function, and cooling is a comprehensive process of multi factors, multi variables and multi effects.
The electric butterfly valve of damping butterfly valve has a wide load range, which is convenient for users to choose, low natural frequency, good vibration isolation effect, compact structure, small overall size, convenient installation and replacement, safe and reliable use, long service life, and strong adaptability to the working environment. It has obvious effect on the isolation of active vibration isolation, passive vibration isolation, shock vibration and solid sound transmission. It is an ideal electric butterfly valve for vibration isolation, noise reduction, vibration pollution control and environmental protection.
