What are the advantages and disadvantages of rubber pneumatic butterfly valve? What are the characteristics??
What are the advantages and disadvantages of our rubber pneumatic butterfly valve? Let me introduce you to this little editor!
1. It can be made into products with various shapes and different hardness, with good elasticity and sufficient strength;
2. It can make the natural frequency of the vibration isolation system lower and have higher damping;
3. No matter under tension, compression, shear and modification, the deformation is relatively large.
Compared with the metal spring pneumatic butterfly valve, its main defects are:
1. Its natural frequency is difficult to achieve below 5Hz;
2. Its ability to resist environmental pollution and temperature change is weak, and its service life is short.
characteristic:
The reason why rubber vibration isolation pads are widely used is that they have durable high elasticity and good performance of vibration isolation, shock isolation and sound insulation; The appearance and pressing are convenient, and the shape and size can be freely selected to meet the requirements of stiffness and strength; It has certain damping performance and can absorb mechanical energy, especially the absorption of high-frequency vibration energy; Because the rubber material and the metal surface can be firmly bonded, it is not only easy to manufacture and install, but also can apply multi-layer superposition to reduce the stiffness, change the frequency range, and the price is low.
Of course, like the rubber shock absorber, the rubber vibration isolation pad also has its weaknesses, such as being vulnerable to temperature, oil, ozone, sunlight and chemical solvent corrosion, composition performance change and aging, and easy to relax. Therefore, the service life is generally about 8 years, but without above corrosion, the service life can exceed 10 years.
The performance of the rubber vibration isolation pad is not only related to the shape and formula of the rubber pad,? It is also related to the hardness of rubber. It has high hardness, large stiffness, large bearing capacity, low hardness, low stiffness and small bearing capacity. The hardness of some rubber damping pads can be divided into 40 ℃, 60 ℃ and 90 ℃. Be careful when selecting them.

Features of pneumatic hard seal flange butterfly valve
1. The valve adopts a three eccentric sealing structure, with almost no wear between the valve seat and the butterfly plate, and has the sealing function of tightening as you look.
2. The seal ring is made of stainless steel, which has the double advantages of hard metal seal and elastic seal. It has excellent sealing performance, corrosion resistance, long service life and other characteristics no matter in low temperature or high temperature.
3. The sealing surface of the disc plate is made of hardfacing cobalt based carbide, which is wear resistant and has a long service life.
4. Large specification butterfly plate adopts quilted frame structure, with high strength, large flow area and small flow resistance.
5. The valve has a two-way sealing function, and can be installed in any direction without the restriction of medium flow direction or the influence of space position.
6. The driving device can be installed in multiple stations (rotating 90 ° or 180 °) for the convenience of users.
