Embodiment Construction
[0013] A differential pressure wind speed detection and control device, including an air supply dust removal branch pipe 1, an electric (pneumatic) regulating butterfly valve 3, a cigarette machine silk collecting box 4, a shredded tobacco conveying pipeline 5, and a differential pressure flowmeter, a differential pressure flowmeter It is a split-type venturi flowmeter, which consists of a split-type venturi flowmeter pressure measuring component 6 and a differential pressure sensor 7; it also includes a split-type orifice flowmeter, which consists of a split-type orifice flowmeter The pressure measuring assembly 2 of the split orifice flowmeter is composed of a differential pressure sensor 7 . In actual operation, when the cigarette machine wire collection box 4 needs shredded tobacco, its own pneumatic switch butterfly valve is opened, and the system negative pressure wind draws shredded tobacco from the pneumatic wire distribution machine into the shredded tobacco conveying ...
