Description
Technical Field
The utility model relates to the technical field of butt-clamped butterfly valves, in particular to a novel butt-clamped butterfly valve with good sealing performance.
Background
The butterfly plate of the butt-clamping butterfly valve is arranged in the diameter direction of the pipeline. In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis at an angle of 0-90 degrees, and when the disc-shaped butterfly plate rotates to 90 degrees, the valve is in a full-open state. The valve is mounted generally horizontally. The butt-clamping butterfly valve has simple structure, small volume and light weight and is composed of only a few parts. And the valve can be opened and closed quickly by rotating by 90 degrees, is simple to operate, and has good fluid control characteristic. When the butterfly valve is in the fully opened position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so that the pressure drop generated by the valve is small, and the butterfly valve has better flow control characteristics. Butterfly valves have two seal types, namely a spring seal and a metal seal. The elastic sealing valve has sealing ring embedded onto the valve body or attached to the butterfly plate.
After the valve plate of the clamp butterfly valve is regulated, the spring tightly pushes the valve rod to fix the valve plate, so that the plate is sealed.
However, the spring is easily worn after long-term use, and a play allowance and a position deviation occur, so that the sealing performance of the valve plate is poor.
