Embodiment 1

[0028] combine Figure 1 to Figure 4 As shown, the butterfly valve of the present invention is schematically shown, and the butterfly valve includes a valve body 100 and a valve core disposed inside the valve body 100;

[0029] Wherein, the valve core includes a shaft body 200 and a first valve plate 300 and a second valve plate 400 arranged in parallel. In this embodiment, the first valve plate 300 and the second valve plate 400 are both circular and concentric It is provided that the radius of the first valve plate 300 is greater than the radius of the second valve plate 400 . The shaft body 200 is rotatably connected to the valve body 100, the first valve plate 300 is located on the drain side of the valve core, the second valve plate 400 is located on the water inlet side of the valve core, and the axis of the shaft body 200 is vertical and passes through the first valve plate 300 The connecting line between the center of the circle and the center of the second valve plat...

Embodiment 2

[0042] This embodiment is basically the same as the above-mentioned first embodiment, the difference between the two is that the valve core includes a shaft body 200 and a first valve plate 300 and a second valve plate 400 arranged in parallel. In this embodiment, the first valve plate 300 and the second valve plate 400 are semicircular, and they are concentrically arranged, and the radius of the first valve plate 300 is larger than the radius of the second valve plate 400 . The shaft body 200 is rotatably connected to the valve body 100, the first valve plate 300 is located on the drain side of the valve core, the second valve plate 400 is located on the water inlet side of the valve core, and the axis of the shaft body 200 is vertical and passes through the first valve plate 300 The connecting line between the center of the circle and the center of the circle of the second valve plate 400, the shaft body 200 is arranged on the diameter side of the first valve plate 300, and t...

Abstract

The present invention relates to the field of water valves, in particular to a butterfly valve, comprising a valve body and a valve core arranged inside the valve body, the valve core includes a shaft body and a first valve plate and a second valve plate arranged in parallel, the shaft body rotates Connected to the valve body, the first valve plate is located on the drain side of the valve core, and the second valve plate is located on the water inlet side of the valve core. The first valve plate and the second valve plate are slidably connected so that they can face or face each other. back movement, the first valve plate is provided with a plurality of first through holes, and the second valve plate is provided with a plurality of blocking parts and a plurality of second through holes, and the blocking parts are used to block or give way to the first through holes, the second through hole is located between two adjacent blocking parts, the shaft is located between the first valve plate and the second valve plate, and the shaft is rotatably connected to the first valve plate, and the shaft is provided with The cam and the first limiting block, the outer peripheral surface of the cam abuts against the first valve plate and the second valve plate, and the second limiting block corresponding to the position of the first limiting block is arranged on the first valve plate.

Description

technical field [0001] The invention relates to the field of water valves, in particular to a butterfly valve. Background technique [0002] Butterfly valve, also known as flap valve, is a regulating valve with simple structure. Butterfly 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. When the butterfly valve is in a state with a large throttling range (that is, the opening angle of the valve plate is small), the valve plate itself acts as a water retaining part in the pipeline, which has a great influence on the water flow state in the pipeline. The shape of the opening formed on the water inlet side is centered on the valve shaft, and the two sides are formed in different states. One side of the valve body and the valve plate form a nozzle-shaped opening, and the other side is similar to a t...
