Description
Technical field
The invention belongs to building and heating fields, and in particular to a kind of detection of low-temperature hot water floor radiation heating buried pipeline
Method.
Background technique
Low-temperature hot water floor radiation heating abbreviation geothermal heating, geothermal heating, which has, saves the energy, thermal efficiency height, Interior Space
The advantages such as gas cleaning and health care, therefore have become widely applied Heat production in existing structure.
Since geothermal heating pipeline is embedded in underground, national regulation is distinctly claimed floor panel heating buried pipeline and is not allow for
Connector, but in practice of construction, it is difficult to avoid that the appearance of connector because of various reasons.Heating pipe is heated generally by by end
It is inserted into connector, because of the influence of the reasons such as operator's construction technology, experience, can exist in pipe hot melting process afterwards
Molten phenomenon, even blocks so that the caliber of joint reduces, simultaneously because pipeline is in back-shaped laying, knee, which can also exist, gives a discount
Phenomenon, superfusion and discounting phenomenon can all cause later period water circulation unsmooth.There are connectors can also give heating work in floor heating pipeline simultaneously
Journey leaves hidden danger, causes pipe leakage.
Therefore, floor heating using it is preceding just to the pipeline of laying carry out give a discount and connector detection it is very necessary.
Summary of the invention
The present invention provides a kind of low-temperature hot water floor radiation heating buried pipeline detection methods, to solve the prior art
In the problem of depositing.
The present invention is to solve above-mentioned technical problem by following technical proposals:
Emit one and consistent first projectile of the tested pipeline bore from tested pipeline one end；
If first projectile does not reach the tested pipeline other end, first projectile is exited, from the quilt
First projectile is re-injected into described tested pipeline 2-5 meters by test tube road one end；
Hot water is filled into the tested pipeline from described tested pipeline one end；
Emit one and consistent second projectile of the tested pipeline bore from described tested pipeline one end；
Tested pipeline is carried out from described tested pipeline one end to suppress processing, stops suppressing when pressure increases and stablizes；
The position that hot water in the tested pipeline is detected using thermal imaging instrument determines quilt according to the hot water position detected
The position of test tube road center tap or discounting.
Preferably, if first projectile smoothly reaches the tested pipeline other end, illustrate the tested pipeline without
Connector or discounting.
Low-temperature hot water floor radiation heating buried pipeline detection method provided by the invention is easily operated, can effectively detect
The position of floor heating buried pipeline connector and discounting, scents a hidden danger in time before heating, solves pipe leakage during urban heat supplying
And the problem of floor heating pipeline circulation is unsmooth, chillout, it provides against hidden trouble, avoids the generation of safety problem.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
It obtains other drawings based on these drawings.
Fig. 1 is the process of the detection method of low-temperature hot water floor radiation heating buried pipeline provided in an embodiment of the present invention
Figure.
Specific embodiment
With reference to the accompanying drawing, further description of the specific embodiments of the present invention.Following embodiment is only used for more
Technical solution of the present invention is clearly demonstrated, and not intended to limit the protection scope of the present invention.
Embodiment 1
The present invention provides a kind of low-temperature hot water floor radiation heating buried pipeline detection methods, as shown in Figure 1, include with
Lower step:
Step 101, from tested pipeline one end transmitting one and consistent first projectile of tested pipeline bore, the present embodiment
Projectile can be emitted using compressed air；
Step 102, whether the first projectile of observation smoothly reaches the tested pipeline other end, if so, entering step 108；If it is not,
Enter step 103；
Step 103, the first projectile is exited, is re-injected into 2-5 meters of tested pipeline from tested pipeline one end by the first projectile；
Step 104, hot water is filled into tested pipeline from tested pipeline one end；
Specifically, because geothermal heating pipeline is longer, be directly injected into hot water because gas block up reason can position it is inaccurate,
It needs first to exit the first projectile before injection hot water, is re-injected into tested pipeline from tested pipeline one end by the first projectile.
Step 105, emit one and consistent second projectile of tested pipeline bore from tested pipeline one end；
Step 106, tested pipeline is carried out from tested pipeline one end suppressing processing, stops beating when pressure increases and stablizes
Pressure, illustrates that the first projectile has arrived at the position of connector or discounting at this time；
Step 107, true according to the hot water position detected using the position of hot water in thermal imaging instrument detection tested pipeline
Determine the position of tested pipeline center tap or discounting, process terminates.
Specifically, since two projectiles are in the two sides of hot water, one of projectile is at the connector of pipeline or discounting, institute
After being determined with hot water position, the position of projectile be can determine, so can landing nipple or discounting position.
Step 108, tested pipeline non junction or discounting, process terminate.
Low-temperature hot water floor radiation heating buried pipeline detection method provided by the invention is easily operated, can effectively detect
The position of floor heating buried pipeline connector and discounting, scents a hidden danger in time before heating, solves pipe leakage during urban heat supplying
And the problem of floor heating pipeline circulation is unsmooth, chillout, it provides against hidden trouble, avoids the generation of problem.
Although preferred embodiments of the present invention have been described, it is created once a person skilled in the art knows basic
Property concept, then additional changes and modifications can be made to these embodiments.So it includes excellent that the following claims are intended to be interpreted as
It selects embodiment and falls into all change and modification of the scope of the invention.
Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the art
Mind and range.In this way, if these modifications and changes of the present invention belongs to the range of the claims in the present invention and its equivalent technologies
Within, then the present invention is also intended to include these modifications and variations.
