Main uses and characteristics of damper for damping butterfly valve
Damping butterfly valve shock absorber is one of the most common butterfly valve shock absorbers. It is also called prestressed butterfly valve shock absorber. The so-called prestress is actually the compressive stress applied to the structure in advance to offset or reduce the tensile stress generated by external loads and maintain the structure from being damaged. This method is the most commonly used method in concrete construction, and is also used in shock absorbers in the past, which increases the acceptance ability of butterfly valve shock absorbers.
Then the main purpose of the damper of the damping butterfly valve is to isolate the vibration of large mechanical equipment such as water chiller, cooling tower, heat pump unit and generator set.
Characteristics of damper of damping butterfly valve:
1. The most important characteristic is that it has two kinds of shock absorber characteristics, namely, the low frequency of the butterfly valve shock absorber and the large damping of the shock absorber, which eliminates the phenomenon of low vibration amplitude of the shock absorber and resonance amplitude of the butterfly valve shock absorber; 2. Wide load range, users do not need to worry about the trouble of selection;
3. Low natural frequency, good vibration reduction and isolation effect;
4. Compact structure, small size, no need for professionals to install;
5. When used, it is not only safe and reliable, but also has a long working life compared with other types of shock absorbers;
6. There is not much demand for the workplace. The most bearable thing for users is that its applicable temperature range is - 40 ℃ to 110 ℃, which is incomparable for many shock absorbers.
From the above characteristics, we can see the strength of the damper of the damping butterfly valve. It not only stops the vibration reduction, isolation and silencing of the vibrating equipment, but also plays a maintenance role, greatly extending the service life of the equipment. To quote a phrase: this is a necessary shock absorber to manage vibration, isolate vibration and reduce noise.
