Abstract

The invention discloses a butterfly valve with high protection performance, which belongs to the technical field of valves, and comprises a valve body and a protection assembly. The valve body is provided with a liquid passing passage for fluid to pass through, and the liquid passing passage is provided with a valve capable of closing it. Valve plate, the valve body is provided with a control handle for controlling the rotation of the valve plate, the protective assembly is installed on the valve plate, the protective assembly includes a protective box, a pressing piece and a protective plate, the protective plate is inclined and The protective plate is slidably matched with the protective box, the pressing piece is placed in the protective box and the pressing piece is in conflict with the protective plate. The invention extends to the front of the side wall of the valve plate through the protective plate, and blocks metal objects or sharp objects that may hit the side wall of the valve plate through the protective plate, so as to prevent the metal objects or sharp objects from damaging the side wall of the valve plate and causing the valve body to fail to seal .

Description

technical field [0001] The invention relates to the field of valves, in particular to a butterfly valve with high protection performance. Background technique [0002] Industrial valves are an important accessory to control the flow of media on industrial pipelines. They can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Industrial butterfly valves Butterfly valve, also known as flap valve, is a regulating valve with simple structure. It can also be used for switch control of low-pressure pipeline medium. Butterfly valve uses structural ceramics as sealing pair, which has excellent corrosion resistance, high temperature resistance, wear resistance and impact resistance. Corrosion performance, can completely replace the entire butterfly valve made of precious metals, which greatly improves the situation where the sealing pair of the butterfly valve is easily damaged under...
