Songxia rubber pneumatic butterfly valve introduces you to the design principle of rubber shock absorber?
Friends who love animation must know "Rubber Fruit". The hero of animation is a resilient person with rubber talent, who can stretch and stretch freely. So do you have a more intuitive understanding of rubber pneumatic butterfly valve? Do you know what the design principle of rubber pneumatic butterfly valve is? Let's follow the Songxia rubber pneumatic butterfly valve manufacturer to have a look.
Rubber is used to eliminate vibration and noise in many fields of engineering technology due to its unique comprehensive mechanical properties, that is, low adjustable modulus and high intrinsic damping, and its ability to bear high load without being damaged under large strain in a certain deformation mode, among which the use of rubber shock absorber equipment to reduce vibration transmission is a common and most effective method.
The rubber can change the stiffness and damping of the shock absorber through different rubber types and adjustment formulas, and the structural mode of the shock absorber can also be selected to obtain the required vibration transmission rate in a certain deformation mode and frequency range. Shock absorber is widely used in various industrial consumption and manufacturing, especially rubber shock absorber products. Because of its various characteristics, it is widely used in vibration isolation of various motor vehicles, aircraft, ships, fans, pumps and other auxiliary equipment. In recent years, some large buildings and bridges have also adopted earthquake isolation rubber damping pads to support buildings.
Songxia Shock Absorber Factory consumes various rubber shock absorbers, spring shock absorbers and metal pneumatic butterfly valves, which are popular with a wide range of new and old customers.

Selection of compensator and selection and device of non-metallic compensator
The compensator has a rectangular section with rounded corners, and a single contraction joint in the pipeline accepts two-dimensional displacement. The elbow receiving track composed of two contraction joints can accept three-dimensional displacement. The rectangular round metal corrugated contraction joints are available in full height and half height types. According to the flue size, users can select multiple corrugated joints according to the stress and strain requirements.
1. After the user selects a suitable compensator according to the thermal displacement of the pipe system, he must at least provide the flow medium in the pipe, the design pressure of the flue gas duct, the maximum temperature during operation, the waveform (full height 216 mm, half height 108 mm) and wave number (single wave number of a single ripple does not exceed 6 waves) selected for the overall dimensions (length and width) of the cross section of the flue gas duct, So as to stop the structural design and manufacturing of the compensator.
2. Maximum allowable shrinkage per wave: full height △ α= ± 24mm half height △ α= ±12mm。
3. Ash baffle: it can not be used for air duct or pipe with little dust, and it should be used for flue with much dust.
4. In order to reduce the number of corrugated sections of bellows, 50% cold drawing shall be considered.
5. The compensator is applicable to places with a sectional area of less than 4.6 square meters and the overall dimensions of the flue and air duct where one side is less than 1.5 m but more than 0.6 mm. The full height corrugated compensator is applicable to all flue ducts.
When the non-metallic compensator is subjected to axial pressure beyond its support, it will suddenly bend and lose the stability of linear form, just like the compressed rod or cylindrical spiral spring. This is inevitable. If the internal pressure accepted by the bellows also exceeds a certain pressure value that it can support, instability will also occur. That is to say, the ability of non-metallic compensator to accept internal pressure generally depends on its stability. Let's introduce the selection and device of non-metallic compensator:
Whether the non-metallic compensator device is correct or not is directly related to the service life of the non-metallic compensator, especially when the non-metallic compensator is replaced. Non metallic compensators of different types and patterns must not be mixed arbitrarily because of their different practical sizes and loads. In addition, if you cannot completely control the skill of changing the non-metallic compensator, we suggest you go to a professional non-metallic compensator shop or an authorized repairer of the non-metallic compensator to stop changing.
