Description

Technical Field

[0001] The utility model relates to the technical field of butterfly valves, in particular to a butterfly valve with variably controlled flow rate. Background Art

[0002] The butterfly valve, also known as the flap valve, is a simple regulating valve that can be used for the switch control of low-pressure pipeline media. The butterfly valve refers to a valve whose closing part (valve disc or butterfly plate) is a disc that rotates around the valve axis to achieve opening and closing. 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 a role of cutting off and throttling on the pipeline. The butterfly valve opening and closing part 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 regulating. The butterfly valve is a valve that uses a disc-type opening and closing part to reciprocate about 90° to open, close or adjust the flow of the medium. The butterfly valve is not only simple in structure, small in size, light in weight, low in material consumption, small in installation size, small in driving torque, easy and quick in operation, but also has good flow regulation function and closing and sealing characteristics at the same time. It is one of the fastest-growing valve varieties in the past decade. The butterfly valve is widely used. The variety and quantity of its use are still expanding, and it is developing towards high temperature, high pressure, large diameter, high sealing, long life, excellent regulation characteristics, and one valve with multiple functions. Its reliability and other performance indicators have reached a high level.

[0003] The application number is 201620825236.3, which discloses a butterfly valve, including a valve body and a butterfly plate. The butterfly plate is connected to the valve body through a valve stem. A ceramic sealing ring is arranged in the valve body, and a ceramic sealing ring in conflict with the ceramic sealing ring is arranged on the butterfly plate. However, there are shortcomings in that the existing demand for variable flow of butterfly valves cannot be met, and the problem that the flow adjustment range of the butterfly valve is not large cannot be solved.
