Abstract
The invention is a method for manufacturing a fireproof regulating valve and the fireproofing regulating valve, and includes the methods for manufacturing an elliptical valve, a blade and a shaft. The method for manufacturing the elliptical valve comprises the processing steps of punching, curling circles, welding, pressing ribs, spot-welding, welding a shaft casing, manufacturing a pipe into a semi-finished product; plasma-cutting the round valve into two parts from the center to form two half circles; spot-welding the two circles into a elliptical circle on the half circles and a connection plate with a reinforced plate, spraying paint plastic, assembling, etc. The method for manufacturing the blade comprises the steps of shearing a rectangular strip on a plate shear; shearing half circles at two ends on a machine shearing machine; pressing out reinforced ribs in the middle of the blade on a bending machine by using a die. The method for manufacturing the shaft comprises the steps of welding an adjustment plate and a shaft to form angle of 90 DEG C minus or plus 1 DEG C, drilling holes, tapping, galvanizing, and assembling. The method has the advantages that an air stream passes through a flat round pipe at a slow flowing speed, a vortex is not easy to generate, and adjustment valves can be manufactured, such as a ventilation regulating valve, fireproofing regulating valve, etc. The fireproofing regulating valve has the advantages of simple, reasonable and practical structure, and convenient and time saving installation.
