Abstract
A new rotameter is provided, wherein, a window through which the scale on the glass tube can be seen is provided on the pipe support, a liquid inflow head and a liquid outflow head are threaded to the two ends of the pipe support; a tapered glass tube with cross section expanding gradually from bottom to top is arranged between the liquid inflow head and the liquid outflow head; a scale representing the flow is provided on the tapered glass tube; a rotator is mounted in the tapered glass tube; a cushion plate is provided at the joint between the liquid inflow head and the tapered glass tube and between the liquid outflow head and the tapered glass tube; wherein, a drain port is arranged on the bottom of the liquid outflow head.
Description
Technical field
The utility model relates to a kind of industry measurement articles for use, especially a kind of novel rotor flowmeter.
Background technology
At present, the spinner-type flowmeter of low discharge in use can be run into a problem, be exactly Control Flow when excessive the rotor of flowmeter can float and get lodged in the lower end of liqiud outlet head, controlled pressure is turned the back rotor down and can not got off at once, the rotor that waits a moment just can get off, and brings inconvenience to use.
The utility model content
At above problem, the utility model provides a kind of novel rotor flowmeter.
The technical scheme that its technical matters that solves the utility model adopts: novel rotor flowmeter, its structure is that the window that can see tapered glass tube scale is arranged on the pipe support, a liquid inlet head and a liqiud outlet head are tightened by screw thread in pipe support two, the vertical tapered glass tube that has a sectional area to enlarge gradually between liquid inlet head and the liqiud outlet head from bottom to top, the scale that the expression flow is arranged on the tapered glass tube, a rotor is arranged in the tapered glass tube, liquid inlet head and liqiud outlet head respectively have cushion film with the junction of tapered glass tube, it is characterized in that there is leakage hole the lower end of liqiud outlet head.
The beneficial effects of the utility model: because leakage hole has been arranged, the excessive back rotor of turning down of flowmeter for small flow controlled pressure can get off at once, has made things convenient for use.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a synoptic diagram of the present utility model.
Among Fig. 11, pipe support; 2, tapered glass tube; 3, rotor; 4, liqiud outlet head; 5, liquid inlet head; 6, cushion film; 7, leakage hole.
Embodiment
The utility model novel rotor flowmeter as shown in Figure 1, its structure is that the window that can see tapered glass tube 2 scales is arranged on the pipe support 1, a liquid inlet head 5 and a liqiud outlet head 4 are tightened by screw thread in pipe support 1 two, the vertical tapered glass tube 2 that has a sectional area to enlarge gradually between liquid inlet head 5 and the liqiud outlet head 4 from bottom to top, the scale that the expression flow is arranged on the tapered glass tube 2, a rotor 3 is arranged in the tapered glass tube 2, liquid inlet head 5 and liqiud outlet head 4 respectively have cushion film 6 with the junction of tapered glass tube 2, in the lower end of liqiud outlet head 4 leakage hole 7 are arranged.
The utility model is owing to increased leakage hole, and the excessive back rotor of turning down of flowmeter controlled pressure can get off at once, has made things convenient for use.
The utility model technology is mainly used in the liquid spinner-type flowmeter of low discharge.
