Embodiment 1

[0028] Example 1: See Figure 1-7 , the present invention provides a technical solution: a blended butterfly valve, including a valve housing main body 1, a flange cover 2, a valve plate main body 3, and a casing main body 4. The valve casing unit with a circular cavity is combined, the upper and lower ends of the valve casing unit are flange surfaces, and the flange surfaces separated by the two valve casing units are provided with a plurality of first bolt holes 11 near the outer edge The first O-shaped groove 12 is provided along the inner edge, and the two valve housing units are surrounded by two flanges 13 perpendicular to the central axis of the valve housing main body 1, and the two flanges 13 are provided with multiple a second bolt hole 14, a second O-shaped groove 15 is provided along the inner edge on the contacting flange surface of the two valve housing units and a plurality of third bolt holes 16 are arranged near the outer edge;

[0029] The two flanges 13 are...

Abstract

The invention discloses a blending butterfly valve which comprises a valve shell main body, flange covers, a valve plate main body and a sleeve main body. The valve shell main body is formed by combining two valve shell units, flanges are enclosed by the two valve shell units, the flanges are correspondingly provided with the flange covers, the valve plate main body is arranged in the valve shell main body, the valve plate main body is composed of a valve plate and a valve shaft, and the valve plate is fixed to the valve shaft; and the valve shaft is sleeved with the two flange covers, a valve shaft opening is formed in one end of the valve shaft, a boss is arranged at the other end of the valve shaft, the sleeve main body extends into the valve shaft opening from the valve shaft opening, a sleeve opening is formed in the sleeve main body, a rotating wheel is arranged at one end of the sleeve main body, and four through hole arc grooves are formed in the rotating wheel. The blending butterfly valve can independently control two kinds of fluid, can realize outlets of three kinds of fluid which include two kinds of single fluid and one kind of mixed fluid, and has excellent control performance; and due to the hindering effect of the valve plate, the fluid can generate turbulent flow in the blending area of the valve plate, and the fluid blending capacity is enhanced due to the turbulent flow.

Description

technical field [0001] The invention belongs to the technical field of fluid blending valves, in particular to a blending butterfly valve. Background technique [0002] Butterfly valve, also known as flap valve, is a regulating valve with simple structure. It is opened and closed by the rotation of the valve plate around the valve shaft. It has the characteristics of simple structure, excellent adjustment performance, small opening and closing torque, and convenient installation. , so it is widely used in fluid distribution system. The blending of fluids is widely used in industry, medicine, aerospace and other fields. The blending valve is installed in the fluid blending pipe section to adjust and control the ratio and speed of fluid blending and other fluid blending parameters. [0003] At present, the plunger type blending valve can only control the flow of one fluid, and the control performance and blending ability are poor. There is a lack of a blending butterfly valve...
