Abstract
The utility model relates to a flow sensor, which is provided with a base, a flow meter body and a cover body, wherein the flow meter body comprises a copper cast casing, a machine core and an impeller; the cover body provided with a calculation display device is arranged at the upper part of the flow meter body; the copper cast casing of the flow meter body is connected and fixed with a demountable split body of the base; the base can be solely prearranged on a pipeline; the cover body and the flow meter body are clamped in a demountable mode for being connected and fixed. The utility model has the advantages of flexible connection and installation, convenient overhauling and maintenance of the whole meter, convenience for replacement and long service life; the pipeline can be periodically or irregularly decontaminated, the accuracy of the whole meter can be ensured and the utility model is favorable for measuring. The utility model is suitable for the measuring of outdoor heat energy and water quantity, and is especially suitable for the environment of water quality containing iron rust.
Description
Technical field
The utility model relates to the measurement sensory device of a kind of flow and calorimetry, especially is applicable to the flow sensor of residents heat energy table and water meter.
Background technology
We know that at present, the homemade flow sensor that is used for heat energy table and water meter mostly is integral type, and promptly flowmeter main part and base are structure as a whole.During installation, flow sensor is directly installed on the pipe system, is used for measurement flow through the concurrent outflow signal of the volume of system water.Existing integral type flow sensor has following many deficiencies: the heat supply water cycle stage that can't avoid high silting, try the water at pipeline, when removing contamination, will certainly result in blockage, core section is caused damage easily, have a strong impact on measuring accuracy simultaneously, can't continue when serious to use; After the sensor internal parts damages, can't carry out part replacement, can only put in order table and change the use cost height; The impeller and the chamber of removing contamination are non-dismountable, can not regularly clean contamination in impeller part and the chamber, are unfavorable for the maintenance of whole table.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provides that a kind of simple in structure, flexible for installation, repair and maintenance is convenient, the flow sensor of long service life.
The technical scheme in the invention for solving the above technical problem is: a kind of flow sensor, it is provided with base, flowmeter main body, lid, the flowmeter main body comprises casting in bronze housing, movement and impeller, contain the lid that calculates display device and be installed in flowmeter main body top, it is characterized in that: the casting in bronze housing of flowmeter main body and the detachable split of base are connected and fixed.
The casting in bronze housing of the utility model flowmeter main body is connected and fixed by screw thread and base.Base portion is a standard base, can be contained on the pipeline in advance separately.Lid detachably engages with the flowmeter main body and is connected and fixed.The movement of flowmeter main body and impeller are also detachable, and movement is the standard movement, are convenient to general.
The utility model is because the flowmeter main body adopts split to be connected with base, base can be installed separately, and against existing technologies, connection is flexible, pipeline can regularly or irregularly be removed contamination, whole table repair and maintenance is convenient, is convenient to change, and can guarantee whole meter accuracy, be beneficial to metering, increase the service life, be applicable to the metering of residents heat energy and water consumption, be specially adapted to contain in the pipeline environment use of iron rust water quality.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model decomposition texture synoptic diagram.
1. bases among the figure, 2. flowmeter main body, 3. lid, 4. loam cake, 5. base cover.
Embodiment
As can be seen from Figure 1, a kind of flow sensor, it is provided with base 1, flowmeter main body 2, lid 3.Base 1 two ends are provided with the threaded connector that links to each other with water pipe line, and flowmeter main body 2 comprises casting in bronze housing, movement and impeller, and movement is the standard movement, are convenient to general.Impeller partly comprises impeller top cover, impeller shaft, impeller blade, water inlet, water delivering orifice, screen pack etc., detachable, the replacing of this six part.Contain the top that the lid 3 that calculates display device and loam cake 4 thereof are installed in flowmeter main body 2, above-mentioned composition belongs to prior art with being connected, and is not describing in detail.
Characteristics of the present utility model are: the casting in bronze housing of flowmeter main body 2 and base 1 detachable split are connected and fixed.More specifically the casting in bronze housing of flowmeter main body 2 is connected and fixed by screw thread and base 1.Base 1 part is a standard base, can be contained on the pipeline in advance separately.Need not measure or remove contamination or put in order when showing repair and maintenance, base 1 can seal with base cover 5, as shown in Figure 2.Lid 3 and soft connection of flowmeter main body 1 separate type for example can adopt detachable engaging to be connected and fixed.
The utility model is because flowmeter main body 2 adopts split to be connected with base 1, base can be installed separately, and like this, connection is flexible, pipeline can regularly or irregularly be removed contamination, whole table repair and maintenance is convenient, is convenient to change, and can guarantee whole meter accuracy, be beneficial to metering, increase the service life, be applicable to the metering of residents heat energy table and water meter, be specially adapted to contain in the pipeline environment use of iron rust water quality.
