Abstract

The invention relates to a butterfly valve, in particular to a quick-mounted butterfly valve. The quick-mounted butterfly valve comprises an upper outer shell, a lower outer shell, a butterfly plate module, an upper shaft module, a triggering rod and a limiting mechanism; the upper outer shell and the lower outer shell are conveniently separated, so that the butterfly plate module is convenientlydismounted, and is conveniently repaired or replaced when being damaged; and the rotating position of the butterfly plate module can be locked to prevent leakage of water currents caused by opening ofthe valve due to higher water pressure during closing of the valve. The lower outer shell is fixedly connected to the end of the upper outer shell; the upper end of the butterfly plate module is rotationally connected with the upper outer shell, and the lower end of the butterfly plate module is rotationally connected with the lower outer shell; the upper shaft module is fixedly connected to theupper end of the butterfly plate module; the triggering rod is fixedly connected to the upper end of the upper shaft module; the lower end of the limiting mechanism is slidingly connected to the upperouter shell; the middle end of the limiting mechanism is inserted in the upper shaft module; and the upper end of the limiting mechanism is clamped on the triggering rod.

Description
