As the traditional manufacturing industry, the cement industry develops to the present, the more and more severe living environment is faced, the environmental protection, the safety, the quality, the cost and the like are not pain points which need to be solved urgently, the transformation and the upgrade are imperative, and the intelligent manufacturing is obviously a new opportunity window. To ensure that the objective of using smart manufacturing is achieved, appropriate precision connections should be made to the field device.
The existing technology is that the gas regulating valve used by our company is connected with an electric actuating mechanism by three connecting rods, and the intelligent manufacturing system controls the electric actuating mechanism by a computer, so that the electric actuating mechanism rotates a valve core by the mutual transmission of the three connecting rods, and finally, a turning plate is opened or closed in a valve body. However, in the actual use process, the mutual transmission of the connecting rods has stroke loss, and the stroke loss exists between the stroke loss and the initial preset value when the stroke loss is finally transmitted to the valve core, so that the actual opening is inconsistent with the set value, and the judgment of the intelligent control system on the gas flow is influenced, so that the problem that the operation of the intelligent manufacturing system is influenced exists in a device in which the three connecting rods are used as the gas regulating valve and connected with the electric actuating mechanism in our company.
