The radius of the ventilation pipe is less than the radius of the aspirating hole in first half-covering tube.
7. a kind of application method of the damage positioning device of underground heat heat distribution pipeline, which comprises the following steps:
Step 1: socket protection structural mechanism is socketed on heat distribution pipeline first, specifically by two the first half-covering tubes and two
Then first buckle and second are connected together in phase by a second half-covering tube two-by-two in conjunction with being socketed on the heat distribution pipeline
In adjacent projections on adjacent two first half-covering tubes and two neighboring second half-covering tube, fastening spiral shell is then utilized
One end that first buckle and described second buckle is fixedly connected by bolt, makes two first half-covering tubes and two described the
Two half-covering tubes in conjunction with being fixedly sheathed on the heat distribution pipeline, and formed between the lateral wall of the heat distribution pipeline one it is closed
Gap；
Step 2: when two first half-covering tubes are connected, will be arranged on the side wall of one of them the first half-covering tube
The 4th conducting block be connected together in the sidewall notches on another first half-covering tube using second spring, make the 4th to lead
Electric block and third conducting block connect；
Step 3: and then be connected in the aspirating hole on first half-covering tube using vaccum-pumping equipment, when vaccum-pumping equipment
When air pressure is greater than the sum of elastic force and outside pressure of third spring, then gas shutoff pearl will receive the effect of air pressure and recycle, and take off
From ventilation pipe, cause in the gap on first half-covering tube and second half-covering tube between the heat distribution pipeline
Air extraction makes to generate the shape close to vacuum between first half-covering tube and second half-covering tube and the heat distribution pipeline
State；And during vacuumizing, since the pressure in gap reduces, fix intracorporal second conducting block of set casing
The internal pressure of shell influences and is detached from second conducting block, and second conducting block and first conducting block are in one
Off state；
Step 4: and then the heat distribution pipeline that good first half-covering tube and second half-covering tube is fixedly mounted is nuzzled
Ground end；When the heat distribution pipeline occurs damaged due to extraneous factors such as corrosion, the hot-fluid in the heat distribution pipeline can flow
Into this section first half-covering tube and second half-covering tube internal voids in, hot-fluid is in first half-covering tube at this time
And will not leak outside in the gap between second half-covering tube and the heat distribution pipeline, allow the heat distribution pipeline after
It is continuous to use a period of time；The heat distribution pipeline breakage simultaneously makes the pressure in first half-covering tube and second half-covering tube
It is strong to increase, connect second conducting block and first conducting block in the intracorporal sliding chamber of the set casing, connection
To the circuit of the third conducting block and the 4th conducting block, external alarm is opened, can be found at the first time and fixed
The damage location of the position heat distribution pipeline, to the breakage on-call maintenance of the heat distribution pipeline or replacement.
