Relationship between vertical stiffness of pneumatic butterfly valve and vibration isolation effect:
If the vertical stiffness of the pneumatic butterfly valve itself exceeds the normal range, the vibration isolation effect will be affected; On the contrary, if it is too large (p0 ＞ 0.8MPa), the vertical stiffness of the pneumatic butterfly valve will not decrease much, but it will put forward higher requirements for the on-site air source and air tightness, which will cause waste. Therefore, the initial working pressure of the pneumatic butterfly valve should be selected moderately (0.4MPa ＜ p0 The vertical stiffness of the pneumatic butterfly valve is relatively large, which affects the vibration isolation effect; on the contrary, if the selection is too large (p0 ＞ 0.8MPa), the vertical stiffness of the pneumatic butterfly valve will not drop much, but it puts forward higher requirements for the on-site air source, air tightness, etc., which may cause waste to some extent. Therefore, the initial working pressure of pneumatic butterfly valve should be selected moderately (0.4MPa ＜ p0 ≤ 0.8MPa); ② For large load (F=107800N) and small load (F=78400N), the initial working pressure should be appropriately larger. ContiTech pneumatic butterfly valve products of German quality, manufactured by Shanghai Dongfeng, not only meet the requirements of commercial vehicles for comfort, but also help to extend the service life of vehicles and reduce the use cost.
November 12, 2015, Shanghai. ContiTech will participate in 2015 China International Commercial Vehicle Exhibition with the theme of "new realm of engineering technology". In combination with the on-site demonstration, the local and German research and development teams of ContiTech will show how the pneumatic butterfly valve system can improve the driving comfort and safety, while reducing the damage of vehicles to the road surface, Reduce emission pollution and realize green transportation. China is the world's largest commercial vehicle market, and pneumatic butterfly valve is one of the important business areas of ContiTech. Diethelm Bauch, Vice President of the pneumatic butterfly valve business unit of ContiTech, came from Germany, which also shows that ContiTech attaches importance to the Chinese commercial vehicle market. German quality, made by Shanghai Dongfeng
ContiTech is a world-famous R&D and manufacturer of pneumatic butterfly valves, whose products are widely used in passenger cars, trucks, trailers, rail transit vehicles and industrial fields. In ContiTech, all factories around the world produce pneumatic butterfly valves according to the same quality standards and ensure product traceability. The 4884N1 series pneumatic butterfly valve assembly on display in this exhibition is a pneumatic butterfly valve model widely used in Europe and domestic trucks, with the advantages of long service life, high pressure resistance, product serialization, etc. At present, this series of pneumatic butterfly valves are selected for the next generation strategic models of domestic OEMs. In order to better respond to the rapidly changing needs of the domestic commercial vehicle market, ContiTech has localized the 4884N1 series. For example, the model of 4884N1 P06 after localization is 4984N P03, both of which have the same performance and quality.
The theme of this exhibition, "New Realm of Engineering Technology", is the global action program of ContiTech, which means to provide excellent quality, cooperate closely with customers and shoulder corporate social responsibility. Constantly carrying out technical innovation and adhering to the global unified quality assurance are the embodiment of the excellent quality of ContiTech.
