Abstract
The utility model provides a double-layer corrugated pipe with the leakage monitoring function, which belongs to a pipe joint element. The end part of the straight edge section of the double-layer corrugated pipe is a sealed structure, one connecting hole or a plurality of connecting holes (2) is/are arranged on one layer of the double-layer corrugated pipe (7), a connecting pipe (3) is welded and connected on the connecting hole(s) (2) and is connected with a pressure meter (6) used for monitoring the failure leakage of the double-layer corrugated pipe through a three-way valve (5), and the connecting pipe (3) is also connected with a valve (4) used for being connected with a vacuum pump for carrying out vacuum pumping between the layers of the double-layer corrugated pipe through the three-way valve (5). The utility model has the advantages that according to the difference of the medium pressure and the atmosphere pressure while the corrugated pipe works, a position between the layers of the corrugated pipe is pumped to a certain vacuum degree, and the corrugated pipe is matched and provided with a pressure meter for monitoring the pressure change between the layers of the corrugated pipe, so whether the corrugated pipe fails to leak or not can be judged, and whether the leakage occurs at the inner layer or the outer layer can be judged. The utility model has the characteristics of simplicity, direct-viewing effect and convenience.
Description
Technical field
The utility model belongs to pipe connector, relates generally to a kind of double-ply bellows that function is revealed in monitoring that has.
Background technique
The method that present monitoring double-ply bellows inefficacy is revealed is to add a fixture at interlayer, the similar piston of this device, the one deck that contacts with medium when double-ply bellows lost efficacy when taking place to reveal, this moment, the pressure of bellows two interlayers became identical with pressure medium, and this pressure promotes piston, is that the leakage of losing efficacy takes place one deck that bellows contacts with medium thereby indicate.But whether this method can not indicate that one deck of bellows discord medium contact to take place to lose efficacy and reveal, this is because that one deck of bellows discord medium contact normally contacts atmosphere, even losing efficacy, revealed by this layer bellows, interlayer and atmosphere UNICOM, its pressure is identical with atmospheric pressure, can not promote piston, so can not indicate one deck of bellows discord medium contact leakage of whether losing efficacy.This just causes a problem, in the case, owing to can not judge one deck of bellows discord medium contact leakage of whether losing efficacy, if and the inefficacy leakage also takes place in one deck that this moment, bellows contacted with medium, then real leakage will take place in bellows, though in most cases be that the one deck that contacts with medium is easier to take place to lose efficacy reveal.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model is to propose a kind of double-ply bellows that function is revealed in monitoring that has, and its that one deck that can simply, conveniently indicate double-ply bellows was lost efficacy reveal.
The utility model is finished its invention task and is taked following technological scheme:
A kind of double-ply bellows with monitoring leakage function, the end of described double-ply bellows straight section is an enclosed construction; On wherein one deck of double-ply bellows, has attachment hole; Described attachment hole is one or more; Be welded to connect adapter on described attachment hole, described connection is taken over by threeway and is connected the pressure gauge that is used to monitor double-ply bellows inefficacy leakage, and described pressure gauge matches with the degree of vacuum of double-ply bellows interlayer; Described connection is taken over and also is connected with by threeway: in order to the valve that is connected with vacuum pump, the double-ply bellows interlayer is vacuumized.
Described attachment hole is two, and two attachment holes are arranged on the diagonal angle of bellows section.
A kind of double-ply bellows with monitoring leakage function that the utility model proposes, pressure medium and atmospheric pressure is different when working according to bellows, and the bellows interlayer is extracted into certain degree of vacuum and is equipped with the variation in pressure that pressure gauge is monitored the bellows interlayer.When bellows skin leakage failure, interlayer and atmosphere UNICOM, the gauge pressure of pressure gauge indication is 0; When bellows internal layer leakage failure, interlayer and medium UNICOM, the pressure of pressure gauge indication is pressure medium; The variation of the force value by pressure gauge indication can be judged bellows leakages of whether losing efficacy, and is that internal layer is revealed or outer leakage; Have simply, intuitively, characteristics easily.

Fig. 2 removes the partial enlarged drawing that is connected adapter for connecting to take over the bellows connection part.
Fig. 3 is the attachment hole position view.
Among the figure: 1, soldering and sealing weld seam, 2, attachment hole, 3, connect and take over, 4, valve, 5, threeway, 6, pressure gauge, 7, double-ply bellows.
Embodiment
With specific embodiment the utility model is illustrated in conjunction with the accompanying drawings, still, the utility model is not limited to these embodiments.
As shown in Figure 1 and Figure 2; A kind of double-ply bellows with monitoring leakage function, the end of described double-ply bellows straight section is an enclosed construction, adopts sealing welding technique for extra that it is sealed in the end of described double-ply bellows 7 straight sections; On wherein one deck of double-ply bellows, set attachment hole 2; Described attachment hole is one or more; Be that skin at double-ply bellows sets two attachment holes 2 among this embodiment; Attachment hole 2 on connection adapter 3 and the double-ply bellows 7 matches and welds with the perforated layer of double-ply bellows, described connection adapter 3 connects by threeway 5 and is used to monitor the pressure gauge 6 that double-ply bellows lost efficacy and reveals, and described pressure gauge matches with the degree of vacuum of double-ply bellows interlayer; Described connection is taken over 3 and connected valve 4 by threeway: vacuum pump is connected with valve 4 when dispatching from the factory, and double-ply bellows 7 interlayers is vacuumized Locking valve 4 behind the certain vacuum degree.When expansion joint is worked by the monitoring pressure table on indicated variation in pressure judge whether bellows leaks.When bellows skin leakage failure, interlayer and atmosphere UNICOM, the gauge pressure of pressure gauge indication is 0; When bellows internal layer leakage failure, interlayer and medium UNICOM, the pressure of pressure gauge indication is pressure medium.
As shown in Figure 3, described attachment hole 2 is two, and attachment hole is arranged on the diagonal angle of bellows section.
Claims (2)
1. one kind has the double-ply bellows that function is revealed in monitoring, and it is characterized in that: the end of described double-ply bellows straight section is an enclosed construction; On wherein one deck of double-ply bellows (7), has attachment hole (2); Described attachment hole (2) is one or more; Be welded to connect adapter (3) on described attachment hole (2), described connection is taken over (3) and is connected the pressure gauge (6) that is used to monitor double-ply bellows inefficacy leakage by threeway (5), and described pressure gauge matches with the degree of vacuum of double-ply bellows interlayer; Described connection is taken over (3) and also is connected with by threeway (5): in order to the special valve (4) that is connected with vacuum pump, the double-ply bellows interlayer is vacuumized.
