How to improve the service life of self-reliance type temperature control pneumatic valve

in the industrial automation instrument, pneumatic control valve is a product that nots allow to ignore, such as temperature control of electric pneumatic valve, self-reliance type pneumatic control valve, pneumatic control valve Siemens, honeywell, temperature control of electric pneumatic valve and so on are more important in terms of energy saving product types, so learn how to use temperature control pneumatic valve is very necessary, now we please self type temperature control of the pneumatic valve research experts to teach you a few action method to improve the service life of pneumatic control valve.
the first is to make temperature control pneumatic valve as far as possible from the start work on the biggest opening, e. g. , %. So, cavitation and erosion damage occurred in self-reliance type pneumatic control valve of pneumatic valve core on the head. With pneumatic valve core damage, the traffic increases, the corresponding temperature control pneumatic valve closed again a bit, so constantly, gradually close, make whole self-reliance type pneumatic control valve of pneumatic valve core, make full use of all roots until pneumatic valve core and the sealing surface damage, cannot use. Work at the same time, the large opening the throttle gap is big, erosion is abate, this is more than the start self-reliance type pneumatic control valve opening in the middle and small open degree on the work to improve life ~.
the other way is through job opening degree increase with the decrease of S to improve the service life of self-reliance type pneumatic control valve. Reduce S, namely, increasing system besides regulating pneumatic valve damage, make the distribution on the pneumatic control valve pressure drop is reduced, in order to ensure the flow through the temperature control of pneumatic valves, inevitably increase the opening, at the same time, the temperature control of pneumatic valve pressure drop decreases, and gets the corrosion, erosion is also reduced. After the concrete measures are: temperature control pneumatic valve orifice throttling pressure drop consumption; Close the series manual pneumatic valve on the pipeline, to control the pneumatic valve to obtain ideal job opening. Using this method to extend the service life of self-reliance type pneumatic control valve, proved to be very simple, convenient and effective.
