Abstract

The invention provides a fluorine butterfly valve. The fluorine butterfly valve comprises a lower valve body, a valve seat, a butterfly plate, bolts, an upper valve body, a gland, a valve body positioning tooth, a gland positioning groove, a pressing plate and a driving device, wherein the lower valve body and the upper valve body are fixed and tightened into a whole through the bolts; the valve seat is arranged on the inner chamber wall of the valve body; the gland is arranged at the upper part of the upper valve body; the gland positioning groove and the valve body positioning tooth are formed in the gland; the pressing plate is arranged at the upper end of the gland; the driving device is arranged at the upper end of the pressing plate. The fluorine butterfly valve is convenient to mount, excellent in sealing performance and high in acid, alkali and corrosion resistance, the valve body guarantees firm and accurate positioning of the valve seat, the valve seat and the gland are fixed on the valve body through the bolts, uniform fastening of the valve seat is guaranteed, the gland positioning groove improves the sealing performance of the valve body and a medium is effectively prevented from leakage.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a fluorine-lined butterfly valve. Background technique [0002] Butterfly valve is a valve that can be opened and closed by rotating around the valve shaft. The valve can be used to control various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. flow. The butterfly valve mainly plays the role of cutting and throttling on the pipeline. The opening and closing part of the butterfly valve is a disc-shaped butterfly plate that rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment. The fluorine-lined butterfly valve is a component used to realize the on-off and flow control of the pipeline system. It has been widely used in many fields such as petroleum, chemical industry, metallurgy, and hydropower. As an important part of the equipment manufacturing industry, the v...
