Abstract
The interior die mould expansion joint of a kind of Novel belt leakage monitoring function, is directly detected revealing medium by gas detector, it is to avoid the erroneous judgement caused because of the vacuum pressure change of detection device, makes detection device more reliable, highly sensitive.
Description
Technical field
This utility model relates to interior die mould expansion joint, and the interior die mould particularly relating to a kind of Novel belt leakage monitoring function is swollen
By detection corrugated tube inter-level dielectric change of component, swollen joint, judges whether corrugated tube leaks.
Background technology
Requiring strict applied environment for corrugated tube Failure Control, corrugated tube is usually designed to double-decker, and every layer all
Can individually bear working condition (temperature, pressure), when wherein one layer lost efficacy after, another layer remains to normally work.In order in time
Find the generation that corrugated tube lost efficacy, need to arrange monitoring device to judge whether corrugated tube lost efficacy.Generally use corrugated tube
Interlayer evacuation mode detects whether corrugated tube leaks, and its operation principle is: when expansion joint dispatches from the factory, and makes corrugated tube interlayer keep
Certain vacuum (negative pressure), in running, when corrugated tube interlayer pressure is equal to zero, illustrates that corrugated tube outer layer leaks；When
When corrugated tube interlayer pressure is equal to operation pressure, illustrate that corrugated tube internal layer leaks.Owing to detection device inevitably exists micro-
Leakage, after expansion joint runs a period of time, detection meter pressure will be designated as zero, at this moment needs again to take out corrugated tube interlayer
Vacuum confirms, if Pressure gauge is quickly designated as zero (or cannot evacuation), then may determine that corrugated tube outer layer
Leakage.This detection method is on the one hand the highest to the sealing requirements of detection device, when detecting meter pressure and being designated as zero, needs
Evacuation confirms again, and execute-in-place is the most inconvenient；On the other hand, even if corrugated tube is not revealed, ripple tube layer
Between pressure also due to the change of temperature and change, easily produce wrong report phenomenon, sensitivity is relatively low.
Utility model content
For solving above-mentioned technical problem, this utility model provides the interior die mould of a kind of Novel belt leakage monitoring function to expand
Joint, is directly detected revealing medium by gas detector, it is to avoid cause because of the vacuum pressure change of detection device
Erroneous judgement, makes detection device more reliable, highly sensitive.
For realizing above-mentioned technical purpose, be the technical scheme is that the interior die mould of a kind of Novel belt leakage monitoring function
Expansion joint, the termination of the double-ply bellows of expansion joint is welded to connect with the technology groove on shell ring, in the end of double-ply bellows
Being provided with monitoring device, monitoring device includes gas detector, the detection pipe of gas detector and the straight length layer of double-ply bellows
Between be connected.
Be arranged with retaining ring on the straight length of this utility model double-ply bellows, retaining ring be provided with for detect pipe through logical
Hole.
The detection pipe of gas detector described in the utility model and the straight length interlayer vertical connection of double-ply bellows.
Gas detector described in the utility model is also associated with valve.
This utility model provides the benefit that: the deficiency existed for the corrugated tube interlayer monitoring alarm used at present,
In conjunction with pipelines and petrochemical pipelines work characteristics, it is proposed that new corrugated tube interlayer monitoring alarm, by corrugated tube, gas detector, valve
The compositions such as door, detection pipe, this expansion joint product possesses non-pressure type leakage monitoring function, and detection sensitivity is high, is particularly well-suited to
Working media is in poisonous and harmful, inflammable, explosive tubing.
Patent of the present invention arranges gas detector detection on double-ply bellows, has the highest sensitivity.Running
By the change of gas detector detection media components in journey, judge whether corrugated tube is revealed.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure: 1, gas detector, 2, valve, 3, double-ply bellows, 4, detection pipe, 5, shell ring, 6, retaining ring.
Detailed description of the invention
In conjunction with the drawings and specific embodiments, this utility model is illustrated, but, this utility model is not limited to this
A little embodiments.
The interior die mould expansion joint of a kind of Novel belt leakage monitoring function, the corrugated tube of expansion joint periphery is by middle wave section
Forming with the straight length at wave section two ends, the monitoring device with monitoring function is arranged on straight length, and monitoring device includes
Gas detector, the detection pipe of gas detector is connected with the straight length interlayer of double-ply bellows, and this connection form is, permissible
The straight length of outer layer corrugated tube opens circular hole, and detection pipe inserts in circular hole, seals circular, then to double-ply bellows layer
Between evacuation, it is ensured that the normal operating condition of corrugated tube.
For ensureing stablizing of monitoring device, can be arranged with retaining ring on the straight length of double-ply bellows, retaining ring is by fixing
Part fixed position, prevent rotate, retaining ring be provided with for detect pipe through through hole.Detection pipe is inserted into circular hole after through hole
Complete the straight length interlayer with double-ply bellows to connect, further, for ensureing detection pipe and the double-ply bellows of gas detector
Straight length interlayer vertical connection, straight pipe can be selected by detection pipe, the centrage weight of the centrage of the through hole of retaining ring and circular hole
Close.
When not detecting, valve can be opened during use by the valve closing whole monitoring device being connected with gas detector
Door uses.
As it is shown in figure 1, gas detector connects with the straight length interlayer of double-ply bellows, to double-ply bellows layer when dispatching from the factory
Between carry out evacuation, in running, if testing result is identical with media components, then show that corrugated tube internal layer is revealed；
If testing result is identical with constituent of air, then show that corrugated tube outer layer is revealed.Owing to the leakage monitoring of the present invention is to pass through
The change of medium composition is carried out, and carries out not by pressure change, even if corrugated tube there occurs a small amount of leakage, it is also possible to inspection
Measuring, therefore, detection sensitivity is the highest.
