Embodiment
A kind of indicator indicating valve opening, with the change point of the difference of its structural type: the indicator that can be applicable to rising stem valve gate series, ono-rising-stem valve series, butterfly valve and spherical valve series of valves aperture, the indicator of described rising stem valve gate series aperture, its structure comprises valve body 12, valve rod 11, thrust bearing 1, drive pulley 2, driven pulley 3, indicator panel 4, slide rail 5, fixing frame 6, lifting linking member 7, belt 8, pointer 9, junction button 10.Described thrust bearing 1 and drive pulley 2 are contained on valve rod 11.Described fixing frame 6 both sides are provided with slide rail 5, indicator panel 4 is installed on slide rail 5, indicator panel 4 connects the thrust bearing 1 be contained on valve rod 11 by lifting linking member 7, indicator panel can be made synchronously to slide up and down with the lifting of valve rod, indicator panel 4 is equipped with driven pulley 3 in two ends above, and driven pulley 3 connects the drive pulley 2 be contained on valve rod by belt 8.Described pointer 9 is fixedly connected on belt 8, and pointer 9 is according to the valve opening limiting value adjustment travelling position of pointer on indicator panel between 0 and 100.Described junction button 10 is fixedly connected with fixing frame 6, fixing frame 6 is fixed on the top of valve body 12 by junction button 10, junction button 10 is provided with long strip attachment hole, screw and valve body 12 is used to fix by long strip attachment hole, the degree of tightness of convenient adjustment belt, guarantee the precision of pointer, the indicator of described composition instruction rising stem valve gate series aperture.The indicator of described ono-rising-stem valve series aperture, be that valve rod is not elevated with the aperture of valve, then between indicator panel 4 and fixing frame 6, do not establish slide rail 5, indicator panel 4 can directly be fixed on fixing frame 6, and other structures are identical with the indicator of rising stem valve gate series aperture.The indicator of described butterfly valve and spherical valve series of valves aperture, is made up of pointer 9, indicator panel 4, fixing frame 6, junction button 10.Pointer 9 connects valve rod, and indicator panel 4 is contained on fixing frame 6, and is fixed on valve body with junction button 10.
Working principle of the present utility model
For rising stem (RS.) valve, when rising stem (RS.) valve is in closed condition, thrust bearing 1 on valve rod 11 and indicator panel 4 are in minimum state, pointer 9 is in zero graduation position, when rotating counterclockwise valve valve rod slowly on move, belt 8 on valve rod 1, dynamic pointer 9 starts slowly to move to the high range place of indicator panel 4, because thrust bearing 1 to be ined succession indicator panel 4 with lifting linking member 7, therefore, indicator panel 4 also synchronously can rise along with the rising of valve rod 11, when valve is opened completely, valve rod 11 rises to highest point, indicator panel 4 also synchronously rises to highest point, at this moment the pointer 9 on indicator panel also points to maximum opening value accordingly, when mounted, due to junction button 10 employing is long strip attachment hole, the degree of tightness of convenient adjustment belt 8, guarantee the precision of pointer.
For ono-rising-stem valve, because valve rod is not with the aperture change lifting of valve, therefore, for this type of valve, slide rail 5 and thrust bearing 1 are not elevated indicator panel 4 in the course of the work, and at this moment they only play the effect of being connected and fixed in application process, also these two component can be omitted.
For ball valve and dish-like valve, this device can be applied equally.
