Abstract
Waterpipe leak hunting method, it relates to method for detecting pipeline technical field；It comprises the steps of: utilizes fire hydrant to carry out pressure measurement and compares, and can leak region with quick lock in；Directly listen at the exposed tube of fire hydrant, valve and exposure point with listening rod and survey the sound that leaks produced by leakage point, so that it is determined that leaking pipe, reduce leak water detdction scope；Listen measuring point the nearest away from leakage point position, listen the sound that leaks measured the biggest；Otherwise, the least；By the water sample collected is carried out chlorine residue detection, i.e. can determine whether it is that water supply network leaks by mesh examination colorimetric.Waterpipe leak hunting method of the present invention, uses the order of the leak source that gradually reduces the scope, determines, it is not necessary to use multiple detecting instrument, easily finds water pipe leak source.
Description
Technical field
The present invention relates to method for detecting pipeline technical field, be specifically related to waterpipe leak hunting method.
Background technology
In water power is transformed water pipe choose especially it is noted that, now basic family has hot water pipe, no matter which kind of
Requirement to water pipe material is the most at a relatively high, has bought the measured water pipe of matter, and ensuing leakage hidden trouble, water to be solved seldom occur
The problem of tube leakage maintenance it may first have to finding leakage cause, water pipe to leak first to make clear is which water pipe partly leaks,
Water pipe leaks and occurs that relatively many parts such as are typically at downcomer, water pipe head at the place.
Can be pulled down if leaking at silk mouth, if the group agricultural machinery adhesive mixing of not quite can buying of leakage is filled.If
Being metal joint, or tighten exactly, just the most again tightening if tightening the most not all right raw material band of adding some points that the most directly removes
Permissible.
If the downcomer of PVC material leaks, it is possible to go the water pipe oneself buying a PVC material to connect, first bad
That root pipe cut off, interface is first packed into one end of pipe, makes other end of to cut off position just with interface additionally
An openning flush, make it just can straighten, then directly sending toward this one end, make two ends have certain intersection then
Distance (length) then disassembles it, spreads upon inside direct two ends the outside with two downcomers with PVC glue.
Water pipe leaks, and should first close power source, before checking leakage cause, first looks at whether power supply closes, because water can be led
Electricity, is susceptible to danger.Then hasten with soft article such as rags, the place leaked to be snarled, prevent current splash everywhere.Look for
To the valve of water pipe, it is tightened, until water no longer flows.
Summary of the invention
Present invention aims to defect and the deficiency of prior art, it is provided that a kind of without using multiple detector
Device, waterpipe leak hunting method simple to operate.
For achieving the above object, the technical solution used in the present invention is: waterpipe leak hunting method, and it comprises the steps of:
1, utilize fire hydrant to carry out pressure measurement to compare, can leak region with quick lock in；
2, directly listen at the exposed tube of fire hydrant, valve and exposure point with listening rod and survey the sound that leaks that produced by leakage point, from
And determine leaking pipe, reduce leak water detdction scope；
3, listen measuring point the nearest away from leakage point position, listen the sound that leaks measured the biggest；Otherwise, the least；
4, by the water sample collected is carried out chlorine residue detection, i.e. can determine whether it is that water supply network is let out by mesh examination colorimetric
Leakage.
The principle of the present invention is: piping failure leaks, and as leakage quantity is relatively big, generally causes pipe network local pressure and reduces, from
The nearlyest pressure of leak source is the lowest, the metallic conduit acoustic frequency that leaks typically between 300～2500Hz, the audio frequency and nonmetal pipeline leaks
Rate between 100～700Hz, chlorine contact with water 30 minutes after contents of residual chlorine otherwise less than 0.3 mg/litre, in Terminal tap water
The content of free residual chlorine is not less than 0.05 mg/litre.
After using said method, what the present invention produced has the beneficial effect that waterpipe leak hunting method of the present invention, uses
Gradually reduce the scope, determine the order of leak source, it is not necessary to uses multiple detecting instrument, easily finds water pipe leak source.
Detailed description of the invention
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to above-mentioned technical side
Case is described in detail.
This detailed description of the invention adopts the following technical scheme that waterpipe leak hunting method, and it comprises the steps of:
1, utilize fire hydrant to carry out pressure measurement to compare, can leak region with quick lock in；
2, directly listen at the exposed tube of fire hydrant, valve and exposure point with listening rod and survey the sound that leaks that produced by leakage point, from
And determine leaking pipe, reduce leak water detdction scope；
3, listen measuring point the nearest away from leakage point position, listen the sound that leaks measured the biggest；Otherwise, the least；
4, by the water sample collected is carried out chlorine residue detection, i.e. can determine whether it is that water supply network is let out by mesh examination colorimetric
Leakage.
The principle of this detailed description of the invention is: piping failure leaks, and as leakage quantity is relatively big, generally causes pipe network local pressure
Reduce, from leak source more close to pressure the lowest, the metallic conduit acoustic frequency that leaks is typically between 300～2500Hz, and nonmetal pipeline
The acoustic frequency that leaks between 100～700Hz, chlorine contact with water 30 minutes after contents of residual chlorine otherwise less than 0.3 mg/litre, pipe network
In Terminal water, the content of free residual chlorine is not less than 0.05 mg/litre.
After using said method, the water having the beneficial effect that described in this detailed description of the invention that this detailed description of the invention produces
Pipeline leak detection method, uses the order of the leak source that gradually reduces the scope, determines, it is not necessary to use multiple detecting instrument, easily find water
Pipe leak source.
The ultimate principle of the present invention and principal character and advantages of the present invention have more than been shown and described.The skill of the industry
The art personnel simply explanation it should be appreciated that the present invention is not restricted to the described embodiments, described in above-described embodiment and description
The principle of the present invention, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, these
Changes and improvements both fall within scope of the claimed invention.Claimed scope by appending claims and
Its equivalent defines.
