Abstract
The utility model discloses a corrugated pipe expansion joint with a warning device. The corrugated pipe expansion joint with the warning device comprises a corrugated pipe, connecting pipes connected at the two ends of the corrugated pipe, a gas tube and the warning device. The corrugated pipe comprises an outer corrugation and an inner corrugation, a warning connector is arranged at the joint of the position between the outer corrugation and the inner corrugation and one connecting pipe, and the warning connector is connected with the gas tube. A cavity placed between the warning connector and the outer corrugation and a cavity placed between the warning connector and the inner corrugation are communicated. The other end of the gas tube is connected with the warning device. The corrugated pipe expansion joint with the warning device is characterized in that the warning device is provided with a gas concentration detection device, gas concentration can be displayed through a display screen, and the warning device is further provided with a warning indicator lamp. When gas leakage happens to the inside of the tube, the gas concentration on the display screen can change immediately, and meanwhile the warning indicator lamp responds correspondingly. According to the corrugated pipe expansion joint with the warning device, whether gas in the expansion joint leaks or not can be detected in real time, so that timely warning is achieved, and thus the security of a pipeline is improved obviously.
Description
Technical field
The utility model relates to a kind of bellows expansion joint, relates in particular to a kind of bellows expansion joint with warning device.
Background technique
At present, when carrying the gas medium such as inflammable, explosive, harmful, it is particularly important that the anti-leak of pipeline seems.On this class pipeline, set up and put the thermal expansion that type metal expansion joint absorbs pipeline and equipment generation.Because these expansion joints are used to the key position of device, once expansion joint lost efficacy, whole device just must stop, and this will cause great waste and impact to producing.Therefore, need in guaranteeing pipeline, in expansion joint safety, also can to the medium in pipe, monitor in real time in operation.
Summary of the invention
The utility model, for the deficiencies in the prior art, proposes gas in the real-time detecting tube of a kind of energy and has or not leakage, and the bellows expansion joint with warning device of energy and alarm.
The utility model is achieved through the following technical solutions technical goal.
With the bellows expansion joint of warning device, comprise bellows and the adapter that is connected in two ends; Described bellows comprises outer ripple and interior ripple; Its improvements are: also comprise tracheae and warning device; Between described outer ripple and interior ripple, be provided with remote alarm interface with the joint of taking over, described remote alarm interface is connected with tracheae, communicates with the cavity between outer ripple and interior ripple; The other end of described tracheae is connected with warning device.
In said structure, described warning device is provided with gas concentration detection apparatus, and shows gas concentration by display screen.
In said structure, on described warning device also with alarm indicator lamp.
The utility model compared with prior art, has following good effect:
1. because adopting double-ply bellows, independent every layer all can meet job requirement, and as a damage layer, another layer can normally be worked.Security is good, and as internal layer leaks, due to skin sealing, medium does not leak, and effectively improves the reliability of expansion joint.
2. being organically combined as a whole of double layer construction and alarm, changes immediately leaking while occurring the concentration of gas on display screen, and its can have or not leakage by Real-Time Monitoring compensator internal layer bellows, has significantly improved the Security of pipeline.
3. warning device is provided with alarm indicator lamp, and when warning device detects the leakage of compensator internal layer bellows, alarm indicator lamp sends warning, has further improved the Security of pipeline.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and in conjunction with the embodiments below.
Shown in accompanying drawing, with the bellows expansion joint of warning device, comprise bellows 1, be connected in adapter 2, tracheae 3 and the warning device 4 at two ends; Bellows 1 comprises outer ripple 1.1 and interior ripple 1.2; Between outer ripple 1.1 and interior ripple 1.2, be provided with remote alarm interface 1.3 with the joint of taking over 2, remote alarm interface 1.3 is connected with tracheae 3, communicates with the cavity between outer ripple 1.1 and interior ripple 1.2; The other end of tracheae 3 is connected with warning device 4.
Warning device 4 is provided with gas concentration detection apparatus, and shows gas concentrations by display screen 4.1, on warning device 4 also with alarm indicator lamp 4.2.
While there is Leakage Gas generation in pipe, on display screen, the concentration of gas changes immediately, and alarm indicator lamp is corresponding simultaneously reacts.
