Abstract

The invention discloses a novel thermal insulation jacket plug valve. The novel thermal insulation jacket plug valve comprises a valve body, a valve cover and a handle; a valve rod, a plug cock and a valve seat are arranged in the valve body; the handle is fixedly connected with the valve cover; the two ends of the valve rod are connected with the valve cover and the plug cock respectively; the valve body is sleeved with a jacket for thermal insulation, and the jacket and the valve body jointly form a thermal insulation cavity; a plurality of first thermal insulation fins are uniformly arranged on the inner wall of the jacket in the circumferential direction of the jacket; second thermal insulation fins are uniformly arranged on the outer wall of the valve body in the circumferential direction of the valve body; fin bodies of the first thermal insulation fins and fin bodies of the second thermal insulation fins are opposite and staggered and enable a flow channel of the thermal insulation cavity to be in an up-and-down shape. By means of the novel thermal insulation jacket plug valve, the thermal insulation performance and effects are better, the thermal insulation time is longer, and higher thermal insulation demands are met.

Description

technical field [0001] The invention relates to a cock valve, in particular to a novel heat-insulating jacket cock valve. Background technique [0002] The thermal insulation plug valve is a closing member or a plunger-shaped rotary valve. By rotating 90 degrees, the channel opening on the valve plug is the same as or separated from the channel opening on the valve body to realize opening or closing. The shape of the valve plug of the plug valve can be cylindrical or conical. In cylindrical plugs, the passages are generally rectangular; in tapered plugs, the passages are trapezoidal. These shapes make the structure of the plug valve light, but at the same time, it also produces a certain loss. Plug valves are most suitable for cutting off and connecting media and diverting, but depending on the nature of the application and the erosion resistance of the sealing surface, it can sometimes be used for throttling. [0003] The jacketed cock valve is a kind of valve in the hea...
