Description

Technical Field

[0001] The utility model relates to the technical field of three-way butterfly valves, in particular to a three-way butterfly valve. Background Art

[0002] The butterfly valve, also known as the flap valve, is a simple regulating valve that can be used for the on-off 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 opening and closing part of the butterfly valve is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening and closing or regulating. It is mainly composed of a valve body, a valve stem, a butterfly plate and a sealing ring. The valve body is cylindrical, short in axial length, and has a built-in butterfly plate.

[0003] When the existing three-way butterfly valve is in use, one end of the existing three-way butterfly valve is usually connected to one end of the external pipeline. When the other two ends of the three-way butterfly valve are connected to the external pipeline, the staff is required to lift the external pipeline and connect the external pipeline and one end of the three-way butterfly valve through a flange. This method increases the efficiency of the connection between the three-way pipeline and the external pipeline.

[0004] In view of this, the utility model provides a three-way butterfly valve. Utility Model Content

[0010] Preferably, the top curvature of the arc-shaped support block is adapted to the bottom of the pipeline.

[0011] The working principle and beneficial effects of the utility model are:

[0012] Through the mutual cooperation of the fixed plate, electric telescopic rod, rack plate, rotating gear, threaded tube, threaded rod, rectangular plate, arc-shaped support block and limit telescopic rod, the rack plate fixed on the electric telescopic rod can be moved to one side under the action of the electric telescopic rod, thereby rotating the rotating gear meshing with the rack plate, thereby rotating the threaded tube, and the threaded rod threadedly connected in the inner cavity of the adjacent threaded tube makes the rectangular plate move upward under the limit of two adjacent limit telescopic rods, so that the arc-shaped support block fixed on the rectangular plate contacts the adjacent pipes, thereby facilitating the support of the adjacent pipes during installation, without the need for the staff to manually lift the pipes for installation, thereby reducing the installation intensity of the staff.
