Diaphragm type check the difference between the pneumatic valve and ball check pneumatic valve

according to the relevant provisions of the check pneumatic valve shall determine the size of the corresponding, pneumatic valve providers must provide the size of the selected data, so you can find under a given flow pneumatic valve fully open the pneumatic valve size thickness. So as to meet the needs of customers, different check use pneumatic valve and the use method is different also, the following steps: for you
barrier type check pneumatic valve
barrier type check pneumatic valve is practical in the pipeline water hammer in easy breeding, gap is a good way to eliminate medium upstream occurrence of water hammer, it often used on low pressure pipe at room temperature, especially suitable for water pipe road, in - something usually medium temperature - - ℃, between the pressure & lt; 。 MPa, but gap type check pneumatic valve can achieve large caliber, DN biggest can reach the mm above;

ball check pneumatic valve ball check pneumatic valve suitable for low pressure pipe, can be made into large diameter; Ball check pneumatic valve shell material can be made of stainless steel, the seals of the hollow spheres can wrap teflon engineering plastics, with is in the pipeline as often corrupt media could also be used, temperature in - things - - Between ℃, its nominal pressure or less. MPa, nominal menstruation category in - Between;
to deal with the compressibility of the fluid with the check pneumatic valve when the choice, should first to evaluate the necessary closed rate, the second step is to choose the satisfied about the necessary check examples of pneumatic valve closed rate. Deal with compressible fluid with check pneumatic valve when the choice can credentials cannot fluid compressibility held in check pneumatic valve of the main point to the same choice, if big medium activity category, used for compressible fluid check pneumatic valve can use a speed reducer, if the medium flow is quickly stop and start the day in a row, as the export of compressor, the use of ups and downs type check pneumatic valve.
pneumatic valve providers must provide the size of the selected data, so you can find under a given flow pneumatic valve fully open the pneumatic valve size thickness. So as to meet the needs of customers.
