Problems solved by technology

[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 fixed, so that the positioning of the valve flap is not accurate enough during assembly, which affects the efficiency of the valve flap assembly, and the assembly is time-consuming and laborious, thus affecting the production and assembly efficiency of the triple eccentric butterfly valve.

Abstract

The invention discloses a valve clack assembling and fixing device for three-eccentric center butterfly valve production and machining, and relates to the technical field of butterfly valve production and machining. The valve clack assembling and fixing device for three-eccentric center butterfly valve production and machining comprises an assembling table, a vertical plate is fixedly installed on the outer wall of one side of the assembling table, a positioning mechanism is arranged in the assembling table, a lifting mechanism is arranged on one side of the assembling table, a moving mechanism and a fixing mechanism are arranged on the other side of the assembling table, and a flange plate is arranged above the assembling table; and a valve seat is arranged in the flange plate. According to the valve clack assembling and fixing device for three-eccentric center butterfly valve production and machining, a valve clack is sucked, meanwhile, the valve clack is conveniently fixed, the stability after fixing is high, the valve clack cannot slip off when the valve clack is moved, the fixing precision of the valve clack is guaranteed, meanwhile, the assembling precision of the valve clack is guaranteed. The air tightness of a finished product of the three-eccentric center butterfly valve is improved, time and labor are saved, and popularization and use are facilitated.
