Abstract

The invention discloses an improved multifunctional butterfly plate based on an electric planer type shaft structure and a butterfly valve formed by the improved multifunctional butterfly plate. The two sides of the butterfly plate are respectively provided with an arch spherical protrusion, the arch spherical protrusion, on one side with a fluid inlet, of the butterfly plate is provided with three flow dividing channels used for flow division and pressure reduction, and the arch spherical protrusion, on one side with a fluid outlet, of the butterfly plate is provided with four flow dividing channels used for flow division and pressure reduction and provided with an installation hole part used for installing the butterfly plate in the radial direction. The multifunctional butterfly plate is improved based on a structure of a traditional butterfly plate of a standard flange type soft seal butterfly valve, high flowing speed of fluid passing through the butterfly plate can be reduced, the flow dividing channels can have the functions of flow division, pressure reduction, cavitation prevention, vibration prevention and noise reduction, and moreover when the butterfly valve is closed, the seal performance of a valve body can be improved.

Description

technical field [0001] The invention relates to a multifunctional butterfly plate and a butterfly valve formed thereof, in particular to an improved multifunctional butterfly plate based on an electric planer shaft structure and a butterfly valve formed thereof. Background technique [0002] Butterfly valve, also known as flap valve, is a regulating valve with simple structure, which can be used for switch control of low-pressure pipeline medium, and can also be used to control air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive The flow of various types of fluids such as media. It mainly plays the role of cutting and throttling on the pipeline. The opening and closing part of the butterfly valve 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 adjustment. [0003] With the acceleration of my country's urbanization process, the amount of valves used in tap wat...
