Abstract
The invention discloses a corrugated pipe expansion joint with an alarm device. The corrugated pipe expansion joint with the alarm device comprises a corrugated pipe, connecting pipes connected to the two ends of the corrugated pipe, an air pipe and the alarm device, wherein the corrugated pipe comprises external corrugation and internal corrugation, alarm connectors are arranged between the at the external corrugation and the internal corrugation and located at the positions where the external corrugation and the internal corrugation are connected with the connecting pipes, and the alarm connectors are connected with the air pipe and are communicated with the cavity between the external corrugation and the internal corrugation; the alarm device is connected to the other end of the air pipe. The corrugated pipe expansion joint with the alarm device is characterized in that that the alarm device is provided with a gas concentration detection device, the gas concentration can be displayed through a display screen, and the alarm device is further provided with an indication light; when gas leakage occurs in the pipe, the gas concentration displayed on the display screen changes immediately, and an alarm indication light gives a response at the same time, By the adoption of the corrugated pipe expansion joint with the alarm device, whether gas leakage occurs in the expansion joint can be detected in real time, an alarm can be given in time, and the safety performance of a pipeline is improved remarkably.
Description
Technical field
The present invention relates to a kind of bellows expansion joint, relate in particular to a kind of bellows expansion joint with warning device.
Background technique
At present, in the time carrying the gas medium such as inflammable, explosive, harmful, it is particularly important that the anti-leak of pipeline seems.On this class pipeline, the standing type metal expansion joint of putting absorbs the thermal expansion that pipeline and equipment produce.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 be guaranteeing in pipeline in expansion joint safety and can monitor in real time the medium in pipe in operation.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, in a kind of detecting tube in real time of proposition, gas have or not leakage, and the bellows expansion joint with warning device of energy and alarm.
The present invention 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 present invention 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, in the time leaking generation, on display screen, the concentration of gas changes immediately, 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 in the time that warning device detects the leakage of compensator internal layer bellows, alarm indicator lamp sends warning, has further improved the Security of pipeline.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment
The invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments below.
Bellows expansion joint with warning device shown in accompanying drawing, comprises bellows 1, is 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 concentration by display screen 4.1, on warning device 4 also with alarm indicator lamp 4.2.
In the time there is Leakage Gas generation in pipe, on display screen, the concentration of gas changes immediately, and alarm indicator lamp is corresponding simultaneously reacts.
