Abstract
The utility model discloses a pointer dial plate display type flowmeter of pipeline liquid, which consists of a sensor, a display and a flexible transmission shaft. Four to seven blades are circumferentially and evenly arranged on a rotary blade shaft provided in the sensor, the output end of the rotary blade shaft is connected with the flexible transmission shaft via a shaft coupling, and the other end of the flexible transmission shaft is connected with the input shaft of the meter of the display via a shaft coupling. The utility model applies an ordinary rotational speed meter, a pointer dial plate displays flow, and a rotation counter registers liquid amount.
Description
The utility model relates to a kind of flowmeter of pointer watch dial display type pipeline fluid, belongs to the improvement of the flowmeter of pipeline fluid.
The flowmeter of the pipeline fluid that uses mostly is glass rotameter now, its main measuring sensor is the tapered glass tube installed downward vertically of a small end and the float that can move up and down within it, when fluid is flowed through tapered glass tube from bottom to top, produce pressure reduction between about float, float rises under this differential pressure action and to its dynamic balance position, the height of float position in tapered glass tube just can show the size of flow.Weak point is that float position is corresponding to the scale on the tapered glass tube, and reading is difficult for accurately.In addition, glass rotameter must be vertically mounted on the pipeline, therefore is not easy to be installed on the instrument face plate, promptly causes the inconvenience of observed reading.Also have, fluid directly passes through tapered glass tube, and fouling on tapered glass tube easily influences reading, and in addition, its resistance to pressure is poor, and should not be used for the measurement of nontransparent fluid.
The utility model purpose is to provide a kind of flowmeter of pointer watch dial display type pipeline fluid.The display of this flowmeter separates with sensor, is connected by flexible drive axle between the two, with the pointer watch dial demonstration flow of display, clear, accurate, directly perceived readability, degree of accuracy height, and, flexible for installation, display can be installed on the instrument face plate easily, and the observed reading operation easily; Simultaneously, but also the displayed record fluid flow through total amount.
For reaching above-mentioned purpose, the utility model is realized by following proposal.It mainly is made of sensor, display and flexible drive axle, it is characterized in that: the rotating vane axle is set in the sensor, circumferentially evenly arrange 4 to 7 blades on the rotating vane axle, the output terminal of rotating vane axle is provided with shaft coupling and is connected with flexible drive axle, the other end of flexible drive axle couples together with the gauge outfit input shaft of shaft coupling and display, and display adopts the ordinary rotational speed Dial of instrument.
Below in conjunction with accompanying drawing the utility model is illustrated.
Accompanying drawing is a structural representation of the present utility model.
1 is fluid inlet among the figure, and 2 is sensor, and 3 is blade, and 4 is fluid egress point, and 5 is shaft joint A, 6 is flexible drive axle, and 7 is shaft coupling B, and 8 is revolution counter, and 9 is gauge outfit, and 10 is dial plate, 11 is display, and 12 is pointer, and 13 is display gauge outfit input shaft, and 14 is the rotating vane axle.
The utility model is work like this, the fluid inlet of sensor is corresponding with fluid egress point to be installed on the pipeline, ducted fluid enters sensor and promotes blade, drive the rotation of rotating vane axle, the rotating vane axle drives flexible drive axle by shaft coupling A and rotates, through shaft coupling B rotation is passed to the input shaft of display gauge outfit again, the rotating speed Dial of instrument is converted into the velocity of rotation of input shaft the deflection amplitude of meter pointer, flow is big more, rotating vane axle rotating speed is fast more, and the deflection amplitude of pointer is big more, according to the corresponding relation of it and flow, the calibration scale dial scale can be realized the pointer watch dial of flow is shown; And the input shaft of display gauge outfit drives revolution counter simultaneously, can write down the total amount that flows through that shows fluid.
The utility model, sensor and displays separated connect by flexible drive axle, clear display, accurate, directly perceived readability, precision height, convenient and flexible installation is easy to observe, the compression resistance height, and measurement range is wide, transparent and nontransparent fluid all can be measured, and is simple in structure, safe and reliable.
