Technical Field

The invention relates to the technical field of liquid measurement, in particular to a water-blocking type flow measuring device.

Background

In the process of industrial production, to the measurement of liquid flow, need measure the liquid of different velocity of flow, guarantee the security in the production process, in order to improve measurement accuracy, when having measured the lower liquid of velocity of flow, use low-range measuring device, when the higher liquid of velocity of flow is measured to needs, need change high-range measuring device, this process is not only extravagant more time, reduce production efficiency, also cause measuring device's idle waste simultaneously, be unfavorable for enterprise reduction in production cost.

Disclosure of Invention

The invention aims to provide a water-blocking type flow measuring device which can accurately measure low flow velocity and high flow velocity liquid.

In order to achieve the purpose, the invention is realized by the following technical scheme:

the utility model provides a water-blocking type flow measuring device, includes the pipeline main part, be equipped with into mouth of pipe and play mouth of pipe in the pipeline main part, the pipeline main part internal rotation is connected with the water-blocking plate, the tip is equipped with the magnet under the water-blocking plate, pipeline main part inner wall upper portion is equipped with hall inductor, hall inductor is corresponding with the magnet.

The water-blocking plate is provided with a rotating shaft, two ends of the rotating shaft are rotatably connected with the pipeline main body, a first opening is formed in the part, located inside the water-blocking plate, of the rotating shaft, a cavity is formed inside the water-blocking plate, and the first opening is communicated with the cavity.

The pivot is the cavity pivot, the pivot both ends are located the pipeline main part outside, the pivot external connection has the tubule.

And a sealing gasket is arranged at the joint of the rotating shaft and the pipeline main body.

The pipeline main body is a plastic pipeline.

And a water inlet pipe and a water outlet pipe are arranged on two sides of the pipeline main body.

Compared with the prior art, the invention has the beneficial effects that:

1. when the liquid flow is measured, the measured liquid continuously impacts the water blocking plate, the water blocking plate can swing, the distance between the magnet arranged on the water blocking plate and the Hall sensors changes, the numerical value displayed by the Hall sensors can be stabilized near a fixed value, the fixed value is converted into a flow value, the numerical value displayed by each Hall sensor corresponds to one flow value, and the liquid flow is measured.

2. Through the quality of control water-blocking plate, realize carrying out the precision measurement to the liquid of different velocity of flow, when needs are measured low velocity of flow liquid, will block the interior liquid reduction of water-blocking plate or take out futilely, when needs measure high velocity of flow liquid, will block and fill up liquid in the water-blocking plate, the size of flow is converted according to hall inductor's reaction value size, has realized the switching of high velocity of flow with the low velocity of flow range, has improved the application range of this device.

3. The pivot is the cavity pivot, the pivot both ends are located the pipeline main part outside, pivot external connection has the tubule, is carrying out the in-process that high flow rate and low velocity of flow liquid flow measurement switched, is connected with outside pumping equipment through the tubule, the rethread the pivot is taken the liquid in the water blocking plate out to guarantee the fast switch-over of measurement process, improved measurement of efficiency.

4. The utility model discloses a pipeline, including pivot, pipeline main part, sealed pad and pipeline main part, pivot and pipeline main part junction are equipped with sealed the pad, sealed pad can seal near the space of pivot, prevents that the liquid in the pipeline main part from flowing along the pivot through this space, has guaranteed the security among the measurement process.

5. The pipeline main part is the plastic conduit, can prevent to produce magnetic force between magnet and the pipeline main part, produces the error to actual measurement result, also can prevent to lead to the fact numerical value to change too greatly because of the magnet breaks away from the magnetic force constraint simultaneously, has guaranteed the stability of whole device operation.

6. Pipeline main part both sides are equipped with inlet tube and outlet pipe, place the different positions on the pipeline that needs the measurement with this measuring device as a whole, can carry out whole assurance to the velocity of flow of pipeline, have improved the utilization ratio of this device.
