What are the main inspection methods for pneumatic butterfly valves?
Today, the manufacturer of pneumatic butterfly valve will share with you the testing method of shock absorber: the shock absorption performance of shock absorber should be verified through the shock absorption test. Damping experiment is usually stopped only when the shock absorber is newly designed and manufactured, and it is not necessary to stop the experiment of shock absorber one by one after mass consumption; Just stop the typing experiment. However, for particularly important shock absorbers, or shock absorbers that need to stop conditioning in the shock absorption experiment before reaching the technical request, they should be tested one by one. It is better to stop the vibration reduction experiment on the whole machine, so the experimental condition is the theoretical working condition; The vibration reduction experiment can also be stopped on a special vibration reduction test bench, that is, to simulate the theoretical working conditions, artificially manufacture the vibration source, and compare the difference between the shock absorber without the shock absorber and the shock absorber installed, so as to evaluate the advantages and disadvantages of the shock absorber.
According to different situations, various vibration excitation methods can be used to artificially produce vibration sources, such as the use of eccentric wheel rotation to drive the sliding block to generate reciprocating displacement excitation, the use of centripetal force generated by unbalanced rotor excitation, the use of compressed air blower excitation, the use of loudspeaker excitation, the use of electromagnetic induction excitation, or the use of special vibration table excitation, etc. The parameters to be measured during vibration test include frequency, amplitude, velocity, acceleration, etc., and sometimes the stress or strain of some parts of the machine. Assuming that the vibration law follows a sine function (such as the vibration caused by the rotor imbalance), the speed and acceleration can be calculated by measuring the amplitude and frequency.

What is the scope of application of plastic coated pneumatic butterfly valve
The plastic coated pneumatic butterfly valve is used more and more widely. Because of its insulation characteristics, many industries need this kind of pneumatic butterfly valve. It not only can maintain electrical appliances, but also has the function of waterproof and anti-corrosion. Appreciation is oil proof. Good sealing also makes the use of pneumatic butterfly valves more extensive. From the earliest power gradually developed to chemical engineering, automatic control and other areas.
First: traffic category. Today's transportation is not only relying on gasoline or thermal power generation, but also the internal circuits of railways, ships and locomotives, as well as domestic cars, are extremely complex, especially can not interfere with each other, so the existence of plastic coated pneumatic butterfly valves is very necessary.
Second: electric power. I don't think it is necessary to say more about the application of this category. In addition to power plants, there are also some power transmission and distribution systems. These are the basic equipment of the city. Needless to say, everyone will understand.
Third: communication equipment and household appliances. We all know that communication systems rely on complex networks to operate. With the power supply of these networks, plastic coated pneumatic butterfly valves can work normally. Because of its good bending performance and smooth internal structure, it can easily pass through some obstacles when threading cables, providing great convenience for life.
