Abstract
The utility model relates to a corrugated pipe compensation device with alarming devices, comprising various compensators composed of metal corrugated pipes and the accessory structures of the metal corrugated pipes. The corrugated pipe compensation device with the alarming devices is characterized in that the corrugated pipes are the double-layer corrugated pipes, and the straight edge sections of one end of the corrugated pipes are provided with communicating pipes. The lower ends of the communicating pipes are hermetically fixed to the straight edge sections of the double-layer corrugated pipes, and the outer layer pipes of the double-layer corrugated pipes corresponding to the connecting positions are provided with through holes. Therefore, the lower openings of the communicating pipes are communicated with the hollow cavities among the double-layer corrugated pipes, and the upper openings of the communicating pipes are connected with the probes of various temperature alarms, gas alarms or pressure alarms. The utility model can monitor whether the corrugated pipes at the inner layers of the compensators leak or not and can alarm in time.
Description
The utility model relates to a kind of FlexbleJoint, particularly a kind of FlexbleJoint with warning function.
The equal alarm free device of existing FlexbleJoint is when bellows can't know in the time of will leaking that because of corrosion just go to remedy up to leakage accident occurring, it is bigger to cause damage.
The purpose of this utility model is exactly in order to address the above problem, and a kind of FlexbleJoint that compensator internal layer bellows has or not the band warning device that leaks and in time report to the police of monitoring is provided.
Technical solution of the present utility model:
A kind of FlexbleJoint with warning device, it includes all kinds of common compensator of being made up of metal bellows and accessory structure thereof, it is characterized in that bellows is a double-ply bellows, on an end straight section of each bellows, be equipped with connecting tube, the lower end of this connecting tube and the sealing of the straight section of double-ply bellows are connected, and corresponding link position has through hole on the external pipe of double-ply bellows, make the connecting tube end opening be communicated with cavity between the double-ply bellows, the probe of suitable for reading and all kinds of temperature, gas or the pressure alarm of connecting tube links to each other.
The utility model changes metal bellows into double layer construction, it can organically be combined as a whole with the probe of all kinds of alarms, it can be monitored compensator internal layer bellows and have or not leakage, and reports to the police when leaking generation, does not influence the work of compensator simultaneously when repair and replacement.Its reliability height, because of adopting double-ply bellows, independent every layer all can be satisfied job requirement, as a damage layer, but another layer proper functioning.Security is good, leaks as internal layer, because outer sealing, medium does not leak, and this point is that the strong gas of corrosivity such as inflammable, explosive, harmful, liquid etc. are particularly important for medium.Accident is had prevention effect, in case the internal layer bellows leaks, warning device can in time be reported to the police, and the staff can take measures, and gets rid of accident potential.The utility model is particularly useful for using in complicated or dangerous harmful medium (as the liquefied petroleum gas) pipeline of higher occasion of security requirement and industry (as petrochemical industry) and composition.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A portion enlarged diagram among Fig. 1.
As Fig. 1,2, the utility model includes by metal bellows 1 and accessory structure spare thereof (as the adapter 2 at two ends, the pull bar 4 of inner liner simple 3 and outside etc.) all kinds of common compensator of forming, characteristics of the present utility model are that bellows 1 is double-ply bellows, on an end straight section 5 of each bellows 1, be equipped with connecting tube 6 (because the more than metal bellows of many FlexbleJoints), straight section 5 sealings of the lower end of this connecting tube 6 and double-ply bellows 1 are connected, and corresponding link position has through hole 7 on the external pipe of double-ply bellows 1, make connecting tube 6 end openings be communicated with the temperature suitable for reading and all kinds of of connecting tube 6 with cavity between the double-ply bellows 1, the probe of gas or pressure alarm links to each other.The link position of corresponding connecting tube 6 and the straight section 5 of double-ply bellows 1, clamping has wire gaze 8 between double-ply bellows 1, and this silk screen 8 has been used for the effect of strutting, and dielectric property can be conducted better.
The utility model is according to the difference of pipeline medium, the alarm that its compensator connect is also different, for pass through in the pipeline be the medium of pressure big (greater than atmospheric pressure) time, can connect pressure alarm, for what pass through in the pipeline is that temperature is when being different from the medium of normal temperature, can connect temperature alarm, for what pass through in the pipeline is when the medium of particular chemical composition is arranged, can connect gas alarm, like this when bellows 1 internal layer of compensator takes place to leak because of corrosion, the characteristic of its medium is just measured by corresponding alarm probe by connecting tube 6, sends alarm signal by alarm, informs that the maintenance man needs in time to change, because when internal layer leaks, outer also intact, so can not cause the accident, also need not to stop production immediately.Thereby solved the leakage alarm problem of bellows, Security improves greatly.
Claims (2)
1, a kind of FlexbleJoint with warning device, it includes all kinds of common compensator of being made up of metal bellows and accessory structure thereof, it is characterized in that bellows is a double-ply bellows, on an end straight section of each bellows, be equipped with connecting tube, the lower end of this connecting tube and the sealing of the straight section of double-ply bellows are connected, and corresponding link position has through hole on the external pipe of double-ply bellows, make the connecting tube end opening be communicated with cavity between the double-ply bellows, the probe of suitable for reading and all kinds of temperature, gas or the pressure alarm of connecting tube links to each other.
2, the FlexbleJoint of band warning device according to claim 1 is characterized in that the link position of the straight section of corresponding connecting tube and double-ply bellows, and clamping has wire gaze between double-ply bellows.
