description	The utility model discloses a butterfly valve seat which comprises a valve seat body. An inner cavity sealing surface of the valve seat body is an inclined cylindrical sealing surface; the water inlet end and the water outlet end of the valve seat body are each provided with a flow guide inclined face with the same sectional area. Due to the design of the inclined cylindrical sealing surfaces, when the valve plate is closed clockwise, the left end and the right end of the valve seat form a slope shape relative to the valve plate, and at the moment, valve plate sealing is not completely equal to interference squeezing sealing of a traditional butterfly valve of the type, and is changed into a combined sealing mode of interference squeezing sealing and simple pressing sealing; the sealing thinking of a traditional center line-type butterfly valve is changed, and the simple press-fit sealing principle is introduced; the design of the flow guide slope increases the overflowing capacity of the valve, meanwhile, th
