The invention discloses a butterfly valve with the good flow regulation stability. The butterfly valve comprises a valve base and a butterfly plate installed on the valve base. A valve rod is fixedlyinstalled on the top wall of the butterfly plate. The top end of the valve rod extends to the upper side of the valve base. A rotating disc is fixedly installed at the top end of the valve rod. An installing ring is in threaded connection with the outer side wall of the top end of the valve rod. An annular installing plate is installed on the top wall of the valve base in a lifting mode. The valverod is sleeved with the annular installing plate. An installing block is fixedly installed on the outer side wall of the installing ring. A connecting block is fixedly installed on the bottom wall ofthe installing block. The valve rod and the butterfly plate are adjusted to the proper position, the installing ring, the installing block and the connecting block are rotated, and the connecting block is fixedly connected to the annular installing plate at the bottom end, so that the connecting block, the installing block, the installing ring, the valve rod and the butterfly plate can be conveniently fixedly connected to the annular installing plate and the valve base. Accordingly, the position of the butterfly plate impacted by liquid is offset can be avoided. The flow regulation effect ofthe butterfly valve is improved, and the butterfly valve is reasonable in design and good in practical effect.
Description
technical field [0001] The invention relates to the technical field of butterfly valves, in particular to a butterfly valve with good flow regulation stability. Background technique [0002] The valve 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. It mainly plays the role of cutting and throttling on the pipeline. Butterfly valves are also called flaps. The valve is a regulating valve with a simple structure. The opening and closing part of the butterfly valve is a disc-shaped butterfly plate, which rotates around its own axis in the valve body, so as to achieve the purpose of opening and closing or adjustment. [0003] When the existing butterfly valve regulates the flow, the position of the butterfly plate is likely to shift due to the impact of the liquid, so that the flow regulation effect of the butterfly valve is poor, so it needs to be improved.
