Abstract
The invention discloses a pneumatic control dust discharging valve which comprises a valve body, two cylinders, two cylinder support components, two link driving components and two valve plate components. The pneumatic control dust discharging valve works mainly in the way that the cylinder piston is put in a vertical reciprocating motion, and drives a pair of lifting lever components through a pair of connecting rod components; a pair of spindle components which are connected with the pair of lifting level components drive the valve plate component on the valve body, so as to realize the opening and closing operations of the dust discharging valve, which facilitates the dust discharging and sealing of the main dust precipitator in a dust removing system, thus ensuring gas pipelines unblocked. The invention has the beneficial effects that the negative pressure is well utilized to keep the valve plate components tightly sticking to the valve body so that the dust discharging valve works with the dust removing system in a fully sealed condition, and has the advantages of compact structure, deft design and good sealing property, thus being one of the indispensible choices for the main dust precipitator in a dust removing system.
