Abstract

The invention provides a range hood inlet triple-eccentric high-temperature cut-off butterfly valve which comprises a cut-off butterfly valve shell. A butterfly plate is arranged in the cut-off butterfly valve shell and mounted on a butterfly plate driving shaft, and the two ends of the butterfly plate driving shaft are mounted on a driving shaft mounting table on the cut-off butterfly valve shell through butterfly plate driving shaft mounting bases. One end of the butterfly plate driving shaft is connected to the output end of a cut-off butterfly valve driving motor through a coupler, and a shell of the cut-off butterfly valve driving motor is installed on the cut-off butterfly valve shell through a butterfly plate driving device mounting base. Quick and precise control over the cut-off valve is realized, and the valve can be very conveniently applied to an automatic control production line.

Description

technical field [0001] The invention relates to the field of control valves, in particular to a three-eccentric high-temperature cut-off butterfly valve at the inlet of a cigarette machine. Background technique [0002] The scope of application of the triple eccentric disc valve can withstand pressure up to 2500 pounds, temperature resistance as low as -196°C, as high as 700°C, sealing to zero leakage, and control ratio as high as 100:1. That is to say, in all kinds of harsh and critical process control pipelines, no matter whether it is a switch valve or a control valve, as long as the type is selected properly, the disc valve can now be used with confidence and at low cost. Triple eccentric butterfly valves are widely used in metallurgy, electric power, petrochemical, water supply and drainage, and municipal construction industrial pipelines where the medium temperature is less than 425°C, and are used for regulating flow and carrying and breaking fluid. [0003] However,...
