Abstract
The utility model relates to a flow controller. The flow controller comprises a pipeline, a flow floater assembly, a small flow control valve, magnetic steel, a flow sensor and a circuit board. The flow floater assembly is arranged inside the pipeline, the small flow control valve is arranged in gaps between the flow floater assembly and inner walls of the pipeline and installed on the flow floater assembly, the magnetic steel is arranged on the flow floater assembly, and the flow sensor is arranged on outer walls of the pipeline and connected with the circuit board. According to the flow controller, movement of the flow floater assembly drives movement of the magnetic steel so that the magnetic steel on the flow floater assembly responses to the flow sensor arranged on the outer walls of the pipeline and produces flow signals, and the flow signals can be utilized to control starting or stopping of a water pump.
Description
Technical field
The utility model relates to a kind of for the automatic flow controller of control of water pump water supply system, especially relates to a kind ofly can to the flow controller of low discharge precision control, belonging to the automatic fluid controller technical field.
Background technology
The low discharge of flow controller because detecting that uses at present, stricter to respective outer side edges, the multiplex metal processing of the material of its cooperation place increases the manufacture difficulty of product and cost.And when using plastic material to make the structure of cooperation place, because being in the water, the plastic cement imbibition is wayward, and tolerance clearance can not be stopped corresponding size, the guarantee properties of product.
The utility model content
The utility model purpose be provide in order to overcome the deficiencies in the prior art a kind of can be to the flow controller of Small Flow Control.
For achieving the above object, the technical solution adopted in the utility model is: a kind of flow controller comprises pipeline, flow float assembly, control valve for small flows, magnet steel, flow sensor, circuit board; Described flow float assembly is arranged in the pipeline; Described control valve for small flows is arranged in the space between flow float assembly and the inner-walls of duct; Described magnet steel is arranged on the flow float assembly; Described flow sensor is arranged on the pipeline outer wall; Described flow sensor links to each other with circuit board.
Preferably, described circuit board has a key reset function module.
Preferably, described pipeline is outside equipped with loam cake, and described loam cake covers flow sensor and circuit board.
The beneficial effects of the utility model are mainly reflected in: flow controller described in the utility model,
Flow controller described in the utility model, utilize the motion of control valve for small flows to drive the motion of the magnet steel on the flow float assembly, so the magnet steel on the flow float assembly produces flow signal with the flow sensor induction that is arranged on the pipeline outer wall, utilize described flow signal can control the startup of water pump or close, be quick on the draw, can survey and control water pump to slight flow accuracy and accurately and timely work.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the cut-open view of flow controller described in the utility model;
Wherein: 1, pipeline; 2, flow float assembly; 3, control valve for small flows; 4, magnet steel; 5, flow sensor; 6, circuit board; 7, loam cake.
Embodiment
Described in the utility model a kind of flow controller as shown in Figure 1 comprises pipeline 1, flow float assembly 2, control valve for small flows 3, magnet steel 4, flow sensor 5, circuit board 6; Described flow float assembly 2 is arranged in the pipeline 1; Described control valve for small flows 3 is arranged in the space between flow float assembly 2 and pipeline 1 inwall; Described magnet steel 4 is arranged on the flow float assembly 2; Described flow sensor 5 is arranged on pipeline 1 outer wall; Described flow sensor 5 links to each other with circuit board 6; Described circuit board 6 has a key reset function module, can in case of emergency use, and can work with the protection water pump; Described pipeline 1 is outside equipped with loam cake 7, and described loam cake 7 covers flow sensor 5 and circuit board 6.The output terminal of described circuit board 6 is connected with motor to control the startup of water pump and close through relay.
The principle of work of described flow controller: when the user fetched boiling water tap, water one flowed in the pipeline, and the flow float will flow together with water, and magnet steel will produce flow signal with the flow sensor induction, thereby starts water pump; When closed tap, after the flow float resetted, flow signal disappeared, and water pump is out of service; The silica gel that control valve for small flows all uses is made, and has guaranteed that stuck phenomenon does not appear in the flow float assembly because the gap is too little in motion process.
Flow controller described in the utility model, utilize the motion of flow float assembly to drive the motion of the magnet steel on the flow float assembly, so the magnet steel on the flow float assembly produces flow signal with the flow sensor induction that is arranged on the pipeline outer wall, utilize described flow signal can control the startup of water pump or close, be quick on the draw, can survey and control water pump to slight flow accuracy and accurately and timely work.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
