Abstract

The invention discloses a dual-valve flow-equalizing device for air exhaust. The dual-valve flow-equalizing device is specially used for equalizing each air sucking inlet of an air exhaust pipeline and provides an effective regulation method for guaranteeing evenness of sucked air quantity of each air inlet in the air exhaust pipeline to effectively extend the even air exhaust pipeline. The device comprises shell-shaped valve bodies (10) which are arranged at intervals along the extension direction of the air exhausting pipeline (40). The bottom of the shell-shaped valve bodies (10) is equipped with an air inlet (11) which is communicated with the external space of the air exhaust pipeline (40); a near-end air port (12) and a far-end air port (13) are correspondingly arranged on two side walls along the extension direction of the air exhaust pipeline (40); and a near-end air valve (21) and a far-end air valve (22) which are equipped with an independent opening regulating mechanism are respectively arranged on the near-end air port (21) and the far-end air port (13).

Description

technical field [0001] The invention relates to a double-valve exhaust air flow equalization device, which is specially used for each suction outlet of the uniform exhaust pipeline, and provides an effective adjustment means to ensure the uniformity of the air intake volume of each tuyere on the exhaust pipeline, so that the uniform exhaust pipe The road can be effectively extended. Background technique [0002] It is a common application technology in ventilation engineering to evenly install multiple suction tuyeres on an exhaust pipeline and keep each tuyere to inhale equal air volume. The technical principle to achieve this effect is that each tuyere maintains the same resistance corresponding to the suction point at the beginning of the exhaust pipeline. In fact, because the negative pressure at the suction point at the beginning decays with the extension of the pipeline, and the pipeline itself has frictional resistance loss along the way, the effective length of the ...
