Abstract
The invention provides a novel butterfly valve which comprises a valve body, a valve flap, a valve rod and multiple flow slowing modules. The flow slowing modules are arranged in a water inflow pipe and used for reducing the water flow speed in the pipe. Filter screens are arranged on a water inlet and a water outlet in a valve cavity respectively and used for filtering out floccules in water. A settling tank is arranged at the portion, between the water inlet and the valve flap, at the bottom of the valve cavity of the valve body and used for settling particles in water. A drain outlet is formed in the bottom of the side wall of the settling tank so that the settling tank can be cleaned regularly. The drain outlet is provided with a sealing cover. The novel butterfly valve has the beneficial effects that the flow slowing modules are additionally arranged to reduce the water flow speed to a certain degree, and thus the damage caused by water flow impact force to the valve flap is reduced; and the filter screens and the settling tank are designed to be detachable so that the floccules and the particles in water flow can be filtered out and settled, and the valve can be regularly detached and cleaned and can be used for a long time.
