Abstract
The invention discloses a small flow rotor flow meter; a pipe rack is provided with a window so as to watch graduate of a taper type glass pipe; two ends of the pipe rack are screwed with a liquid inlet joint and a liquid outlet joint; the vertical taper type glass pipe with a cross section area gradually enlarging from bottom to top is arranged between the liquid inlet joint and the liquid outlet joint; the taper type glass pipe is provided with graduate representing flow; a rotor is arranged in the taper type glass pipe. When control pressure is decreased, the rotor can go down right away, so usage is easy.
Description
Technical field
The present invention relates to a kind of industry measurement articles for use, specifically a kind of low discharge spinner-type flowmeter.
Background technology
At present, the spinner-type flowmeter of low discharge in use can encounter a problem, and when control flow is excessive exactly, the rotor of flowmeter can float and get lodged in the lower end of liqiud outlet head, and controlled pressure is turned rear rotor down and can not be got off at once, the rotor that waits a moment just can get off, and brings inconvenience to use.
Summary of the invention
The object of the invention is to solve prior art not enough, a kind of low discharge spinner-type flowmeter is provided.
The technical solution adopted for the present invention to solve the technical problems: low discharge spinner-type flowmeter, its structure pipe support has the window seeing tapered glass tube scale, pipe support two is by screwed tight liquid inlet head and a liqiud outlet head, the vertical tapered glass tube that a sectional area expands gradually is had from bottom to top between liquid inlet head and liqiud outlet head, tapered glass tube there is the scale representing flow, a rotor is had in tapered glass tube, liquid inlet head and liqiud outlet head follow the junction of tapered glass tube respectively to have cushion film, it is characterized in that there is leakage hole the lower end of liqiud outlet head.
Beneficial effect of the present invention: owing to there being leakage hole, flowmeter for small flow controlled pressure is excessive to be turned rear rotor down and can get off at once, facilitates use.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.
As shown in Figure 1, low discharge spinner-type flowmeter, its structure pipe support 1 has the window seeing tapered glass tube 2 scale, pipe support 1 two is by screwed tight liquid inlet head 5 and a liqiud outlet head 4, the vertical tapered glass tube 2 that a sectional area expands gradually is had from bottom to top between liquid inlet head 5 and liqiud outlet head 4, tapered glass tube 2 there is the scale representing flow, a rotor 3 is had in tapered glass tube 2, liquid inlet head 5 and liqiud outlet head 4 follow the junction of tapered glass tube 2 respectively to have cushion film 6, have leakage hole 7 in the lower end of liqiud outlet head 4.
The present invention is owing to adding leakage hole, and flowmeter controlled pressure is excessive to be turned rear rotor down and can get off at once, facilitates use.
