Abstract

The utility model relates to a water flow switch which can filter foreign impurities, adjust the starting flow capacity and measure the flow capacity. A rotating shaft with an impeller matched in a pressing way is connected with a water flow switch body; a cover, a spring clip and a Hall component box of a Hall component connected with a control line are arranged on the water flow switch body, and are connected with a circuit; a strong magnetic filter screen is installed at a water inlet; an impeller blade can be selected and determined according to the requirements of the starting flow capacity. Insoluble substances and iron powder in the water can be filtered and sucked out so as to ensure the normal work of the water flow switch, and simultaneously, the stable staring flow capacity can be formed according to the width of the blades of different impellers; the flowing rate of the water can be calculated through the times of N and S electrodes of the strong magnetic iron ring passing through a Hall circuit, and the flow capacity can be calculated under the condition that the diameter of the water flow switch is definite.

Description

Energy impurity screening and adjustment start flow and measure the water switch of flow

Technical field

The utility model relates to a kind of water switch device that rotates magnetic induction, especially can filtered water in impurity and adjust the startup flow of water and measure the water switch of flow.

Background technique

At present, the effect that known water switch only can play water flowing energising, cut the supply of water and electricity, but do not have can filtered water in impurity and adjust the startup flow of water and measure the water switch of flow.

Summary of the invention

For overcome existing water switch can not filtered water in impurity and adjust the startup flow of water and measure the deficiency of flow, the utility model provides a kind of water switch, the effect that it can not only play water flowing energising, cut the supply of water and electricity, and impurity and adjust the startup flow of water and measure flow in can filtered water.

The technological scheme that its technical problem that solves the utility model adopts is: a strong magnet ring and a slice filter screen are formed a strong magnetic filter screen that can be used for sealing of being with glue with rubber, be press-fitted the strong magnet ring and select for use two or multi-disc impeller sets to lump together with rotating shaft by the requirement that starts flow, the multi-disc blade should evenly distribute around the impeller, and it is identical to establish blade quantity, the different multiple impeller of blade width also press fit in the rotating shaft and fixes, to be equipped with on the rotor stationary axle of rotating shaft by the aperture insertion water switch body of strong magnet ring side of strong magnet ring and impeller, the rotor stationary axle is a disalignment, the other end is inserted in the rotor stationary axle of lid in the opposing party's aperture of rotating shaft, two stationary axle are concentric, and will cover on the water switch body, tighten with spring clamp, load onto strong magnetic filter screen at the water inlet of water switch, on the water switch body, be provided with the Hall element box, perfusion is connected to the Hall element of guide line on fixing in box, and is connected with institute distribution road.When water ingoing stream switch water inlet, the strong magnet ring of strong magnetic filter screen can be with the end sucking-off of the iron in the water, filter screen can filter out not molten thing and exist in the foreign material chamber of strong magnetic filter screen, so that many cleaning, the cleaning of water and the proper functioning of water switch have been guaranteed like this, when water is punched on the combined impeller, the rotating shaft meeting is rotated by the startup flow of having set, the strong magnet ring rotates thereupon, the N of strong magnet ring, S is extremely every through Hall circuit once just to export a voltage pulse, thereby can calculate the flow velocity of water outlet and calculate the flow of water outlet by the water flowing diameter of water switch.

The beneficial effects of the utility model are, undissolved substance in the water and iron end can be filtered also sucking-off to guarantee the proper functioning of water switch, blade width by different impellers is combined into stable startup flow simultaneously, N by the strong magnet ring, the S utmost point calculates the flow velocity of water outlet through the number of times of Hall circuit, and under the certain situation of water switch latus rectum, calculate flow, simple in structure.

Embodiment

In the drawings, a strong magnet ring (9) and a slice filter screen (16) are formed the strong magnetic filter screen (4) of being with foreign material chambeies (18) with strong magnetic filter screen rubber body (15), be press-fitted strong magnet ring (9) and also be pressed in succession in the rotating shaft (3) and fix with rotating shaft (3) by starting two impellers (6) that requirement selects for use, the square aperture of strong magnet ring (9) that will be press-fitted the rotating shaft (3) of strong magnet ring (9) and impeller (6) is inserted on the stationary axle (2) of water switch body (1), after going up, the stationary axle (2) that the opposing party's aperture of strong magnet ring (9) is inserted in the lid (14) that " O " type circle (8) is housed compresses, and be inserted in spring clip (7) in 4 holes of water switch body (1) and fix, the water intake of water switch body (1) is loaded onto strong magnetic filter screen (4), the fixing Hall element of going up of perfusion in Hall element box (11), will go between (13) reach and are connected with circuit.When water from water inlet (5) when entering, strong magnet ring (9) in the strong magnetic filter screen (4) can be with iron end sucking-off, filter screen (16) can leach undissolved substance, make the water cleaning to guarantee the proper functioning of water switch, water impulsion impeller (6) makes rotating shaft (3) rotate the N of strong magnet ring (9), the S utmost point can rotate thereupon together, and every process Hall element box (11) is once, just defeated voltage pulse, thus can calculate the flow velocity of water outlet and calculate the flow of water outlet by latus rectum.

Claims

A kind of energy impurity screening and adjustment start flow and measure the water switch of flow, be connected with the water switch body by the rotating shaft that is press-fitted impeller, lid, spring clamp are arranged on the water switch body and be connected to the Hall element box of the Hall element of guide line, be connected with institute distribution road, it is characterized in that: at water inlet strong magnetic filter screen is housed, impeller blade can be selected setting for use by the requirement that starts flow.
