Abstract

The invention discloses an operating mechanism for simultaneously opening and closing two ball valves. The operating mechanism comprises a first quadrilateral hinge mechanism, a second quadrilateral hinge mechanism, a T-shaped connecting mechanism, an operating hand wheel, a clamping mechanism, a first ball valve rod, a second ball valve rod, a first key and a second key, wherein the first quadrilateral hinge mechanism is connected with the first ball valve rod, the second quadrilateral hinge mechanism is connected with the second ball valve rod, the T-shaped connecting mechanism is connected with the first quadrilateral hinge mechanism and the second quadrilateral hinge mechanism, the operating hand wheel drives the T-shaped connecting mechanism and is connected with the same, the first key is positioned on the first quadrilateral hinge mechanism, the second key is positioned on the second quadrilateral hinge mechanism, and the clamping mechanism is used for clamping the first key and the second key. The T-shaped connecting mechanism is connected with the two same quadrilateral hinge mechanisms, and the operating hand wheel drives the T-shaped connecting mechanism, so that the two ball valves can be simultaneously opened and closed.

Description

technical field [0001] The invention relates to an operating mechanism, in particular to an operating mechanism for simultaneously opening and closing two ball valves. Background technique [0002] On the medium and long pipelines of industrial equipment, sometimes the pipelines are connected in parallel, and two ball valves are installed at the same time. At the work site, it is required to open and close at the same time, or one valve is opened and the other valve is closed. This requires two sets to be equipped with two operating valve switching devices, and the purpose of simultaneous valve switching cannot be achieved. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an operating mechanism for simultaneously opening and closing two ball valves, which utilizes two identical quadrilateral hinge mechanisms, and the T-shaped connecting mechanism is respectively connected to two identical quadrilateral hinge mecha...
