The introduction of pneumatic diaphragm pump valve ( 2)

flash and cavitation effect not only the calculation of flow coefficient, prevent flash flash and cavitation and cavitation in liquid medium. In the process of practical production. Will form the vibration and noise, make the pneumatic valve life is short, so when choosing pneumatic valve should be to prevent flash and cavitation of the pneumatic valve.
overview of pneumatic diaphragm pump body and select the relevant factors:
commonly used is through single-seat, pass-through two-seater, angular, diaphragm, small flow rate, tee, eccentric rotating, butterfly, sleeve, spherical, etc. Prior choice of pneumatic valve, pneumatic valve type choice of the diaphragm pump in the selection of pneumatic valve diaphragm pump is the most important link. There are many kinds pneumatic diaphragm pump body. To control the process of medium, the careful analysis of process conditions and parameters, collect enough data and solution system requirement for diaphragm pump, according to the collected data to determine the pneumatic valve type to be used. Specific choice, can consider from the following aspects:
pneumatic valve core shape structure mainly based on the selected flow characteristic and factors such as unbalanced force.
pneumatic valve, pneumatic valve seat joint face every time shut down severely friction. Pneumatic control valve flow is smooth, the wear resistance when fluid medium is suspending liquid containing high concentrations of wear particles. Pneumatic valve internal information to hard.
can satisfy regulating function, under the condition of corrosion due to the corrosive medium. Try to choose simple structure of pneumatic valve.
should choose pneumatic valve core and pneumatic valve seat materials by temperature, pressure changes small pneumatic valves. Medium temperature, pressure, when the medium temperature, high pressure and large variations.
