Abstract

The invention discloses an inclined wafer butterfly valve which comprises a clamping frame. A first hand wheel is arranged outside the clamping frame; one end of the first hand wheel extends into theclamping frame so as to be fixedly connected with a first threaded rod; a sliding inclined block slidably connected with the inner wall of the clamping frame is tightly attached to the end, away fromthe first hand wheel, of the first threaded rod; a telescopic column is tightly attached to the inclined face of the sliding inclined block; a moving plate is welded to the end, away from the slidinginclined block, of the telescopic column; and a moving column is slidably connected to the top end of the moving plate. According to the inclined wafer butterfly valve, by arranging the sliding inclined block, in the clamping frame, the first hand wheel is rotated to drive the first threaded rod to rotate, the first threaded rod drives the sliding inclined block to slide along the inner wall of the clamping frame, the telescopic length of the sliding inclined block is equal to the length of the moving plate, the inclined angle of the inclined surface of the sliding inclined block is 30 degrees, and the inclined face of the sliding inclined block drives the telescopic column to slide along the inner wall of the clamping frame, so that the telescopic column is conveniently controlled to drive the moving plate to move.

Description

technical field [0001] The invention relates to the technical field of wafer butterfly valves, in particular to an oblique wafer butterfly valve. Background technique [0002] The butterfly plate of the wafer butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0°-90°. When the rotation reaches 90°, the valve When the sign is fully open, the valve is generally installed horizontally. The wafer butterfly valve is simple in structure, small in size and light in weight. The valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body. Therefore, the pressure drop generated by the valve is very small, so it has good flow control characteristics. Butterfly valves have two ...
