Summary:The invention provides a method for manufacturing a ventilation valve body. The method comprises the following specific steps: S1, calculating the expanded size of the ventilation valve body, and cutting and blanking plate materials according to the expanded size; S2, carrying out crimping treatment on two sides of cut plate materials, and forming a flanging of a ventilation adjustment hole; S3, stretching and stamping the crimped plate materials to form a connecting hole; S4, using a stretcher to stretch and shape two semicircles of the ventilation adjustment hole; S5, using a stamping press to stamp and integrally shape the ventilation valve body; S6, carrying out crimping treatment on two ends of the ventilation valve body after the ventilation valve body is stamped and shaped; S7, welding connecting seams of the ventilation valve body. According to the method, the plate materials are stamped and integrally shaped for manufacturing of the ventilation valve body, a traditional casting mode is replaced, the
