Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts all other
Embodiment shall fall within the protection scope of the present invention.
Secondly, each marque referred in the present invention or " first ", " second ", "upper", "lower", "left", "right",
The technical terms such as "front", "rear", " remote ", " close ", be all the technical terms clearly known already in technical field and in order to
It describes that embodiment is convenient and some positions for carrying out or definition spatially, not limitation of the present invention, therefore no longer does excessive
It explains.
To solve the above-mentioned problems, it is realized by carrying out innovative design to water flow detecting element by the in the present invention
The combination of one test side, the second test side and insulating spacer member prevents solid pollution in detection water flow well
The attachment or blocking of object；It is isolation material by the insulating spacer member, the first test side, the second test side pass through conduit and institute
State insulating spacer member connection, corresponding detection conducting wire and detector extend to pipe under test across conduit, and the later period can be with
The replacement of detection conducting wire and detector is carried out by pulling conducting wire.By above-mentioned design, it had both ensured and had effectively detected in real time
Streamflow regime in turn avoids pollutant attachment or contact tube wall failure, and repairs and be very convenient to compared to other existing sides
Case has the advantages that protrusion.
Further, the technical scheme adopted by the invention is that:
A kind of Water flow detector, including the first test side of water flow detecting element 1 and the second test side of water flow detecting element 2
It is linked together by insulating spacer member 3, structure is simple and is not easy adhering contaminant；First detection signal line 1-2 and first
Conductive head 1-3 connection is detected, water flow detection circuit 4 is connected to by the first test side conduit 1-1；Second signal lines 2-2
It is connected with the second detection conductive head 2-3, water flow detection circuit 4 is connected to by the second test side conduit 2-1；When there is water flow,
First detection conductive head 1-3 and the second detection conductive head 2-3 can be flooded by water flow simultaneously, be formed into a loop by water flow, resistance value
Sharply decline, water flow detection circuit can capture this variation immediately, and be converted into streamflow regime signal and transfer out.
Further, the first detection conductive head 1-3 of the present invention and the second detection conductive head 2-3 ontology are arranged exhausted
The external contact measured inner cavity of pipe in the inside of edge insulating element 3, only end face；When there is water flow, water flow can be by the first detection
The detection of conductive head 1-3 and second conductive head 2-3 floods, and is equivalent to the first detection conductive head 1-3 and the second detection conductive head
The access that 2-3 is formed by water flow, resistance value moment reduce；It, can due to the isolation of insulating spacer member 3 after water flow disappears
To prevent the continuous of residual water, interrupts and passed through water flow between the first detection conductive head 1-3 and the second detection conductive head 2-3
The access of formation, to help quickly to detect the presence or absence of water flow.
Further the first detection signal line 1-2 and the second signal lines 2-2 is connected to water by conduit
Current detection circuit, and the diameter of the first detection conductive head 1-3 and the second detection conductive head 2-3 are less than first inspection
The internal diameter of end conduit 1-1 and the second test side conduit 2-1 are surveyed, pulls signal lines for the first detection conductive head 1-
3 and the second detection conductive head 2-3 is extracted out or is inserted into from conduit, is dismantled insulating component when avoiding maintenance or replacement, is exempted from
It has gone to tear caused extra work open.
Finally, maintenance replacement detection conducting wire and probe, the first detection signal line 1-2 and described second are examined for convenience
It surveys signal wire 2-2 and is all made of elastic wire, and conduit transition is round and smooth, it is ensured that is easy to operate when maintenance or replacement.
Based on above-mentioned special designing, the present invention is adapted to the application of various occasion water flow detections, especially solves
Water flow detection in toilet bowl sewage draining pipe, specifically there is following characteristic:
(1) insulating spacer member 3 is perpendicularly fixed on fluid course, and the first detection conductive head 1-3 and the second detection are led
Dateline 2-3 is isolated and is positioned at liquid stream by insides of pipes, and is no more than inner tubal wall；
(2) first detection conductive head 1-3 and the second detection conductive head 2-3 are only no more than inner tubal wall in end face, will not be by liquid stream
In solid hang knot；
(3) first detection conductive head 1-3 and the second detection conductive head 2-3 can be passed through by corresponding signal lines
Conduit realizes that replacement can be repaired by not dismantling insulating spacer member 3 and other devices of outside etc..
In order to clearly illustrate, we are illustrated by taking liquid stream when detecting closet flushing in siphon pipe as an example；
Embodiment: insulating spacer member 3 is perpendicularly fixed in toilet siphon pipe 6 by detection hole, and the first detection is conductive
The detection of head 1-3 and second conductive head 2-3, which is respectively corresponded, to be arranged on insulating spacer member 3, and conductive end face is by being dielectrically separated from
Water flow is in the through-hole connection toilet siphon pipe 6 of component 3.
Wherein, the first detection that the first detection signal line 1-2 and the second signal lines 2-2 are connected is conductive
The detection of head 1-3 and second conductive head 2-3 is the exposed conducting surface structure in end, the first detection signal line 1-2 and described second
Signal lines 2-2 selection plain conductor connection rustless metal conductive head, or the conductive wire for selecting suitable length exposed are straight
It patches into the first test side conduit 1-1 and the second test side conduit 2-1, and ensures end and insulating spacer member 3
End face or be slightly retracted.
When flushed, water flow flows downward along 6 inner wall of toilet siphon pipe, as vertical the first detection of covering conductive head 1-3
When with the second detection conductive head 2-3, so that access is connected；It is contacted since test side only has end face with water flow, and does not probe into closestool
Inside siphon piping 6, the dirt being mingled in water flow is fluid state, there is current scour in addition, so the first detection conductive head 1-3
Dirt, which will not be infected with, with the second detection conductive head 2-3 causes line clogging or failure.
In conclusion being adapted to be similar to the spies such as toilet siphon pipe 6 using Water flow detector provided by the invention
The detection needs of water flow in the various fluid channels very constructed, and have structure it is simple, not vulnerable to pollution, prevent erroneous detection wrong report etc.
Characteristic has wide application scenarios.
