Main uses and characteristics of damping spring shock absorber
Damping spring shock absorber is a kind of spring shock absorber that we are familiar with. It is also called prestressed spring 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 usually used in shock absorbers, which increases the acceptance ability of spring shock absorbers.
Then the main purpose of the damping spring damper is to isolate the vibration of large mechanical equipment such as water chillers, cooling towers, heat pump units and generator sets.
Characteristics of damping spring damper:
1. The main characteristic is that it has two kinds of shock absorber characteristics, namely, the low frequency of spring shock absorber and the large damping of rubber shock absorber, which eliminates the low amplitude of rubber shock absorber and the resonance amplitude of spring 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 damping spring shock absorber. 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.

Applicable scope of several different types of pneumatic butterfly valve joints
Pneumatic butterfly valve connector is used to connect the pneumatic butterfly valve with other parts of the connector. According to the different connection methods, it can be divided into ferrule type connector, external thread connector, reducing connector, etc. These different types of pneumatic butterfly valve connectors are applicable to which connection situations? Come and have a look with Aoguang.
(1) External thread connector: mainly used to connect the local junction box with the pneumatic butterfly valve. The local box is opened, plugged into the connector, and fixed with the lock nut.
(2) Internal thread connector: mainly used for screw connection between cable pipe and pneumatic butterfly valve.
(3) Ferrule type connector: mainly used for the connection of pneumatic butterfly valve and steel pipe. It is not necessary to thread the ferrule connector on the steel pipe for installation. The connector is firmly clamped at the end of the steel pipe, which is convenient for installation.
(4) Plug in joint: It is mainly used to insert the inner diameter of the pneumatic butterfly valve into the embedded pipe with small dense clearance and convenient installation.
(5) Reducing joint: It is mainly used when the diameter of the steel pipe is inconsistent with that of the pneumatic butterfly valve, and can be arbitrarily increased or decreased according to the on-site installation requirements.
Because the structural design of these joints is different, the connection methods used to connect pneumatic butterfly valves also have their own characteristics. Users should select the corresponding connection methods of pneumatic butterfly valves according to the needs of the application site and the characteristics of the connection situation.
