Many factors need to be considered when designing the electric butterfly valve.
First of all, the weight and volume of the shock absorber must be considered when designing the shock absorber, and the shock absorber must have certain damping characteristics.
Secondly, the design of the electric butterfly valve should also consider the future service environment. The electric butterfly valve designed to withstand the ambient temperature is affected by other factors.
Third, because the electric butterfly valve equipment has a certain bearing capacity, its load needs to be considered in the design to avoid the overload in the future use process, which will bring more problems.
Fourthly, the design of shock absorber must consider its damping performance to ensure that it can better meet the needs of application.
The loss sine load of butterfly valve can be either constant amplitude load or variable load with known variation law. Regardless of the type, as long as the known fatigue strength value of butterfly valve and the measured or calculated stress level of components are used, one of the methods in the cumulative loss theory described above can be used to estimate the fatigue loss. For constant amplitude load levels, the Miner criterion is an effective standard. The material strength can be determined by the test of constant amplitude load level. For the sinusoidal load whose amplitude variation law of electric butterfly valve of butterfly valve is known, the Henry nonlinear loss theory is more accurate. The same result will appear when the scanning frequency passes through the resonance frequency of the butterfly valve of the test piece under the sinusoidal scanning test environment. It can be seen from Henry's nonlinear theory that the cycle ratio on the load level of each butterfly valve electric butterfly valve must be calculated.
Under the sinusoidal scanning test of electric butterfly valve of butterfly valve, the calculation method of cycle ratio of various load levels is as follows: the characteristics of response changing with frequency can be known from the electric butterfly valve or strain gauge of butterfly valve fixed on the pipeline and the known test frequency scanning range, so that the response stress level can be divided into various amplitude levels. The duration of amplitude level of electric butterfly valve of each butterfly valve is known, so when the average frequency of each level is known, the cycle ratio of each level can be calculated, and then the cumulative loss.
