Abstract

The invention provides an improved anti-theft butterfly valve, and belongs to the technical field of butterfly valves. The improved anti-theft butterfly valve comprises a bottom plate, a first fixing block and a rotating mechanism; the first fixing block is fixedly connected to the upper end of the bottom plate, a rhombic rod is fixedly connected to the upper end of the first fixing block, and a second fixing block is fixedly connected to the upper end of the rhombic rod ; the rotating mechanism comprises a second gear, a third gear, a second rotating bearing, a fourth gear, a first I-shaped wheel, a fourth rotating bearing, a second I-shaped wheel, a connecting belt, an eighth rotating bearing and a driving part, the second gear is fixedly connected to the upper end of the bottom plate through a rotating shaft, and the third gear is fixedly connected to the lower end of the third gear; and the second rotating bearing is fixedly connected to the lower end of the rotating shaft, and the fourth gear is rotationally connected to the circumferential surface of the third gear in an engaged manner. The rotating function of equipment is further improved through the arranged rotating mechanism, and therefore the automatic opening and closing functions of the equipment are further improved.

Description

technical field [0001] The invention belongs to the technical field of butterfly valves, in particular to an improved anti-theft butterfly valve. Background technique [0002] Butterfly valves are suitable for pipelines transporting various corrosive and non-corrosive fluid media in petroleum, chemical, hydropower, water supply and drainage, smelting, energy and other engineering systems, and can be used to regulate and cut off the flow of media. At present, domestically produced butterfly valves usually adopt two modes of worm gear transmission and handle transmission. Among them, medium and small-caliber butterfly valves with handle transmission are more popular in the market. For example, the "butterfly valve handle" with the published Chinese patent No. The handle structure suitable for the handle transmission butterfly valve is mainly composed of a valve body, a valve seat, a butterfly plate, a valve stem, a handle and a wrench. However, the butterfly valve handles of ...
