Pneumatic diaphragm control valve failure and solution

Followed by light to dark colors, followed by the danger of increasing gradually. Therefore, the pneumatic diaphragm valve design improves the process, provides effective information and supports the size of the danger, helping to identify the weaknesses in the design process. The traditional sense of safety interlock function to measure the reliability of the product's pneumatic valve reliability is mainly four indicators, namely, reliability R (T), unreliability (or failure probability), F (T) , Fault density function f(t) and failure rate λ(T). The safety interlocking function in the traditional reliability index is based on the reliability index, the safety interlocking function incorporates some related statistical indicators, the reliability, availability, the probability of failure and the failure of the average failure-free time, etc. [40] This is analyzed by the statistical FMEDA. In this paper, the result of the analysis of the pneumatic diaphragm valve FMEDA shows that the safety interlocking function obtains the reliability index. Reliability is usually defined for device-specific design constraints, and the working device needs to implement its meanBe probability function.
