Abstract
Description
technical field
[0001] The invention relates to the technical field of production and processing of butterfly valves, in particular to a disc assembly and fixing device for production and processing of triple-eccentric butterfly valves. Background technique
[0002] Triple eccentric butterfly valve means that the shaft center of the valve stem deviates from the center of the disc plate and the center of the body at the same time, and the rotation axis of the valve seat has a certain angle with the axis of the valve body channel. During the production and processing of the triple eccentric butterfly valve, the valve disc needs to be assembled and fixed, and then the valve The stem is inserted into the valve clack, and the valve clack needs to be fixed before the valve stem is inserted into the valve clack, so as to facilitate the smooth insertion of the valve stem into the valve clack, but some valve clack assembly and fixing devices are inconvenient during use. The flap is f...
