Further, described securing means below is provided with the packing seal circle, and described rotating shaft top is arranged with plain washer.
Further, also be arranged with spring arch clasp above described plain washer.
Further, be provided with thrust washer between described torsion spring and described main body.
Further, be fixed in described rotating shaft by nut above described handle.
Further, described securing means is for being with reeded ferrule structure.
Further, described base is provided with for the fixed block that is fixed with valve, and described fixed block is screw.
The beneficial effects of the utility model are: the utility model is connected the valve rod of described rotating shaft and ball valve by securing means, upper platform by fixed block and valve is connected and fixed, thereby described rotating shaft can be with ovable valve stem to rotate, after rotating described handle, valve open, after unclamping described handle, under the effect of described torsion spring, described rotating shaft just can automatically reset, throttle down; Thereby realize the best effect of fixing, sealing and automatically reset and close.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
