Detailed description of the invention
The quantitative testing device revealed for external pressure expansion joint (is assumed V1=1L, V2=2L, V3 by the hydrops groove of particular design
=3L, outage aperture also can be different), gsm wireless emitter composition.When expansion joint is without revealing, then quantitative testing device is not sent out pre-
Alert signal.When expansion joint is revealed, working media preferentially imports hydrops groove V1 region by expansion joint discharging tube, and water logging senses
Device or leakage sensor sense hydrops, and GSM1 wireless transmitter is sent signal, and discharged by outage, if amount of leakage is little
In the output of outage, then hydrops groove V1 region cannot be crowded with all the time, shows micro-leakage of expansion joint, and expansion joint is without changing
Can be continuing with；If when working media imports hydrops groove V1 region by expansion joint discharging tube, being crowded with, then import hydrops groove
V2 region, two outage discharge opeings simultaneously, and GSM1, GSM2 wireless transmitter are simultaneously emitted by signal, if cannot be crowded with all the time, then
Prompting expansion joint amount of leakage is appropriate, and improves degree of concern；If when working media imports hydrops groove V1 by expansion joint discharging tube
Region, is crowded with, and then imports hydrops groove V2 region, is crowded with, subsequently into V3 region, and three outages discharge opeings simultaneously, and GSM1,
GSM2, GSM3 wireless transmitter is simultaneously emitted by signal, if cannot be crowded with all the time, then prompting expansion joint amount of leakage increases, and needs to improve
Degree of concern, and prepare to change；Change the most immediately if being crowded with.
Fig. 3 is quantitative testing device specific embodiment on outer pressure axial type expansion joint.This quantitative testing device also may be used
Exist for the expansion joint needing detection leakage of other pattern, such as external pressure straight pipe type, bypass straight pipe type, external pressure straight tube pull rod type etc.
The expansion joint of the various types listed in GB/T12777-2008 " metal corrugated pipe expansion joint general technical specifications ".
As it is shown on figure 3, one end of corrugated tube 4 is connected with spacing ring flat-plate 3, the other end is connected with pressurized ring flat-plate 7；Corrugated tube 4
It can be one group, it is also possible to be many groups, if many groups are then linked together by intervalve 5.Inlet tube assembly 1 and outer tube 6
Be connected with pressurized ring flat-plate 7, then, inlet tube assembly, outer tube 6, pressurized ring flat-plate 7, corrugated tube 4 outside between formed an envelope
The pressurized zone closed.Outlet 11 one end is connected with spacing ring flat-plate 3, and the other end is movable end, and is radially staying with pressurized ring flat-plate 7
There is a small amount of gap, can axially opposing slide between outlet 11 and pressurized ring flat-plate 7, to compensate pipeline tensile and compress position
Move.
Between spacing ring flat-plate 3, the inner side of corrugated tube 4, intervalve 5, pressurized ring flat-plate 7, outlet 11, formation one is non-is subject to
Intermediate pressure section.Arranging quantitative testing device 12 in pressurized ring flat-plate 7 outer lower portion, quantitative testing device 12 detects and leaks out from gap
Medium, adds black box 18 at gap location, and black box 18 does not affect between outlet 11 with pressurized ring flat-plate 7 can axial phase
To slip, prevent medium from revealing in a large number from gap simultaneously, also have and all leakage media are all concentrated guiding expansion joint discharging tube
The effect of 13, black box 18 includes sealing ring 8, seals ring flat-plate 9, seal cover board 10, and sealing ring 8 is by sealing ring flat-plate 9 and close
Gap location is sealed by capping plate 10, seals ring flat-plate 9 and arranges expansion joint discharging tube, if revealing, liquid passes through expansion joint discharge opeing pipe flow
Enter quantitative testing device 12, send different strong and weak signal, for maintenance or the replacing of expansion joint by detecting different amount of leakage
Real-time early warning is provided.
Owing to the present invention is by the amount of leakage of medium is carried out detection by quantitative, possess non-pressure type leak detection function,
Detection sensitivity is high, and utilizes gsm wireless emitter technology, in conjunction with the construction features of External Pressure Type expansion joint, it is possible to achieve to non-
The amount of leakage in pressurized chamber detects in real time, and maintenance or replacing for expansion joint provide real-time early warning.
Owing to corrugated tube uses external-compression type structure, the wave number of corrugated tube can arbitrarily increase and not limited by post buckling pressure
System, therefore expansion joint can realize the biggest nose balance amount, and the axial rigidity of expansion joint is the lowest simultaneously, it is possible to reaches to reduce
The effect of displacement counter-force.
