Further, air bag and ventilation pipe, inflating pump and ventilation pipe, pressure gauge and ventilation pipe, gas bleeder valve and ventilation
The connection of pipeline, equal tee and ventilation pipe uses stainless steel larynx band band tightener.
It is an object of that present invention to provide a kind of for quickly determining the method that indoor water pipe leak position occurs, this method packet
Include following steps:
Air bag is put into inside pipeline by the first step by access hole, and placement location is located at 0.5m- below storey floors to be measured
At 1m, placement location can be calculated by snorkel length reading；The outlet of pipeline side is temporarily sealed using plug simultaneously
It is stifled；
Second step is inflated in air bag by inflator, when the pressure of pressure valve reaches 0.35-0.4MPa, air bag with
Pipeline filling is close, will be more than pipeline (generally PVC material) maximum compression capability if pressure is more than 0.4MPa.?
Under this pressure of 0.35MPa, sacculus is close with inner wall of the pipe, and air bag frictional force is up to 13.74kN (PVC and rubber in DN100 pipeline
Glue coefficient of friction 0.5), it is sufficient to guarantee no seepage and no leakage at air bag.
Third step is poured water from inspection socket, check pipeline whether leak；If without leak, by gas bleeder valve by gas in air bag
Discharge；The first step and second step are repeated, next stage pipe detection is carried out.
In conclusion advantages of the present invention and good effect are as follows: the present invention uses new construction technology, and each layer separates survey
Examination, when leaking, then need to only check that this layer of pipeline, remainder layer pipeline have been subjected to inspection, it is not necessary to check again for, avoid wasting
A large amount of human and material resources.Gas cylinder pressurization aerated capsule of the invention, capsule and pipeline filling are close, will not leak, under layer-by-layer
Aerated capsule is put, pipeline does water filling test.Pressure gauge can intuitively reflect gasbag pressure, and gasbag pressure is excessive, be easily damaged pipe
Road, pressure is too small will to cause water to flow out from gap, be unable to reach test effect.
