Share the butterfly medium sensitivity and life expectancy of the pneumatic valve

pneumatic valve
the life of a butterfly pneumatic butterfly valve normal failure modes is leakage, leakage and including leakage and leakage, leakage is mainly caused by erosion or corrosion, leakage mainly seal damage caused. Commonly referred to as the life of the number refers to the use time of sealing pair or action, its main depend on the type of medium, medium temperature and medium pressure, frequency of opening and closing and opening and closing speed, etc. , so as to satisfy the working condition of the materials and make the necessary heat treatment, such as: material abrasion resistance and electrochemical corrosion resistance and fatigue strength, etc. And the life of the seal and the rationality of the structure design, the manufacture precision of closely related.

butterfly butterfly pneumatic valve medium sensitivity pneumatic valve is suitable for conveying water, oil, gas and solid two phase and gas-solid two-phase flow, and other medium of piping system for switch or control device, and control pneumatic valve seal on the sensitivity of the medium is design one of the important factors to consider when, when the design mainly from the material selection and structure form up an. Such as the cut off for the dust content in the medium high pneumatic valve, butterfly is to select the rubber materials with good sex of elastic sealing ring, or with the clear structure of multi-layer metal hard seal, seal of relative motion at the same time in seal itself can remove particles such as dirt, or purging, cleaning function is used to reduce dust pollution of the seal.
