Abstract
The utility model provides a liquid measuring device. The technical proposal is as follows: a spiral impeller is arranged in a shell body of the device, a magnet is fixedly arranged on an outer ring of an impeller support, a sensor is arranged on the inner wall of a scroll fluid, the magnet and the inner wall of the scroll fluid are arranged on a same horizontal line, and a circuit of the sensor is led out from the shell body to be connected with a terminal block which is fixed at an outer shell. Thread connecting parts are arranged at a water inlet and a water outlet, and the thread connecting parts can regulate the feeding amount and the emission amount of liquid through threads. When in use, a line on a counting display is connected with the terminal block on the outer shell of the sensor, the liquid flow drives the spiral impeller to rotate during the process of measuring the liquid flow rate, the magnet on the spiral impeller support is closed to the sensor which is arranged on the same horizontal line once for each rotation of one circle, the sensor accordingly generates an induced electrical pulse, and the induced electrical pulse is transmitted to an electronic display counter through a guide wire, thereby effectively displaying the liquid flow rate.
Description
One, technical field:
The utility model relates to a kind of flow rate of liquid measurement mechanism.
Two, background technology:
Mostly there are drawbacks such as precision is not high, use inconvenience in the existing flow rate of liquid device of measuring, has a strong impact on measurement effect.
Three, summary of the invention:
The utility model is exactly at the problems referred to above, and a kind of flow rate of liquid measurement mechanism is provided, to improve the degree of accuracy of measuring flow rate of liquid.The technical solution of the utility model is: be provided with helical runner in the device case, magnet of fixed installation on impeller support outer shroud, on the rotary fluid inwall, be provided with a sensor, magnet and rotary fluid inwall are on same horizontal line, this sensor circuit is drawn from housing, links to each other with the connection terminal that is fixed on shell.Be provided with threaded connector at water inlet and water delivering orifice place, threaded connector can be by the inlet and the discharge rate of threaded adjusting liquid.In use, circuit on the count display is connected with connection terminal on the sensor outer housing, in the process of measuring flow rate of liquid, magnet and same horizontal sensor that flow of liquid drive helical runner rotates on the helical runner support that whenever rotates a circle are approaching once, sensor just produces induction electrical pulse one time, this induction electrical pulse imports the electronics display counter into by lead, thereby effectively shows flow rate of liquid.
Four, description of drawings:
Accompanying drawing is a structural representation of the present utility model;
1. liquid introducing ports among the figure, 2. connection terminal, 3. sensor, 4. magnet, 5. helical runner, 6. threaded connector, 7. liquid outlet, 8. housing, 9. threaded connector, 10. impeller support.
Five, embodiment:
In device case, be provided with helical runner (5), a fixed installation magnet (4) on impeller support (10) outer shroud, on the rotary fluid inwall, be provided with a sensor (3), magnet (4) and rotary fluid inwall are on same horizontal line, sensor (3) circuit is drawn from housing (8), links to each other with the connection terminal that is fixed on shell (2).Locate to be provided with threaded connector (6) and threaded connector (9) at liquid introducing port (1) and liquid outlet (7), threaded connector (6) and threaded connector (9) can pass through threaded adjusting liquid import volume and discharge rate.In use, circuit on the count display is connected with sensor (3) connection terminal (2), in the process of measuring flow rate of liquid, the magnet (4) that flow of liquid drive helical runner (5) rotates on helical runner (5) support that whenever rotates a circle is approaching once with same horizontal sensor (3), sensor (3) just produces induction electrical pulse one time, this induction electrical pulse imports the electronics display counter into by lead, thereby effectively shows flow rate of liquid.
