Do you know the application of rubber pneumatic butterfly valve in bulldozers??
When it comes to rubber pneumatic butterfly valve, you will surely think of its application in automobiles as the first response. Do you know its application in bulldozers? Now follow us to have a look. There are two main contents:
First: At present, there are many kinds of damping pads for the starter, and rubber damping pads have been widely used in the field of vibration and noise reduction of the starter due to their advantages such as small size, low cost, and easy adjustment of elasticity and stiffness. Therefore, almost all the supports of bulldozer diesel engines use damping rubber at present. The rubber vibration damping is applied at the support part, and the separation surface is highly requested, and the high temperature resistance and oil erosion resistance should also be paid attention to. Not only pay attention to the vibration isolation when the diesel engine is rotating at high speed, but also pay full attention to the vibration isolation when the diesel engine is idling, starting, stopping, and preventing the resonance of all parts of the engine body. It is an example of rubber support used for a high-power diesel engine. The diesel engine has a power of 735KW, a mass of 5.7t, and four points of support are used on the rack. The shape of each rubber support is shown as a bonded rubber with oil resistant surface. The rubber support itself is arranged at an inclination of 30 °. When disassembling the diesel engine, it can be taken out from the horizontal plane between the side feet of the diesel engine and the side of the engine body. After the diesel engine is installed, the diesel engine and the engine body are level. The second diagnostic process of bulldozer's weakness is: the application effect on the track guide wheel. Taking the rubber damper installed at the guide wheel of a tracked bulldozer as an example, the installation position of the rubber damper is shown, indicating its shape. Its shape is like a wedge shaped "sandwich", which is used to cushion and reduce vibration in both vertical and horizontal directions. Pneumatic butterfly valve structure damping rubber working temperature: - 30~60 ℃; Maximum amplitude of vibration load: 270KN; Load frequency: 012~200Hz; Operating frequency of main load: 4 ～ 8Hz. For small amplitude vibration loads, the shock absorber can absorb more than 80% of the vibration energy; For the impact load, more than 50% of the impact energy can be dissipated.
The above is the simple arrangement of Songxia Xizhen pneumatic butterfly valve. I believe that you also have some control, and I hope to help you. If you want to know more, you can call the staff of the manufacturer to provide you with satisfactory answers.

2、 Features of intelligent pneumatic 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.
