Abstract
The utility model relates to a loose joint ball valve which is composed of a valve body, a valve rod, nuts for fixing the valve rod, a handle, a fixing sleeve for a gland bush, the gland bush and a ball body, wherein the gland bush and the valve body which are arranged on the ball valve are connected into a whole through the fixing sleeve for the gland bush. In normal times, the gland bush and the valve body are connected into a whole; when the ball valve needs repairing and pipelines are installed, the gland bush on the ball valve can be demounted from the valve body just by unscrewing the fixing sleeve for the gland bush on the ball valve. Compared with the existing ball valve, the ball valve of the utility model has the characteristic that the gland bush can be demounted from the valve body. The loose joint ball valve can be especially used as a valve installed on a tap water pipe.
Description
The utility model belongs to valve technology field, particularly a kind of easy-to-dismount loose joint formula ball valve.
Just can not dismantle after gland on the existing ball valve and valve body combine as a whole, this makes troubles for installation of pipeline; Can not keep in repair ball valve simultaneously,, can only change ball valve, compare waste like this in case ball valve breaks down.
Task of the present utility model is at non-detachable deficiency between existing above-mentioned gland of existing ball valve and the valve body, and demountable loose joint formula ball valve between a kind of gland and the valve body is provided.
Task of the present utility model is finished as follows: by the gland fixed cover they being combined as a whole between gland on the ball valve and the valve body, wherein is scyewed joint between gland fixed cover and the valve body.At ordinary times, gland and valve body combine as a whole.Need ball valve is keeped in repair and during pipe laying, as long as the gland fixed cover on the ball valve is unscrewed, the gland on the ball valve can be disassembled from valve body, this gives the installation of pipeline and the maintenance of ball valve has been brought many facilities in operation.
The utility model is compared with existing ball valve, has demountable characteristics between gland and the valve body, when ball valve breaks down, can keep in repair ball valve.In addition, the utility model also has the function that can make Pipe moveable joint, and this has brought facility for being installed in of pipeline in operation.The utility model is particularly suitable as a kind of valve that is installed on the running water pipe.
