The diaphragm valve is the key component of the deashing device in a pulse bag filter. It affects the investment cost, operation cost and the floor area, as well as the wide application of the dust removers on jetting performance directly. The development of a low pressure valve with a diameter of 100 was optimized by orthogonal test. The large-sized low-pressure diaphragm valve with the jetting and technical economic performance has been widespread used in market, it was better than small-sized one by parameter comparison between another similar ...
