Abstract
The invention relates to a steel-sleeving-steel directly-buried internal-pressure type compensator with a leakage point troubleshooting device. The compensator comprises a compensator body, an external protective sleeve and a reinforced sleeve, the external protective sleeve is arranged outside the compensator body, and the reinforced sleeve is arranged outside the external protective sleeve. A corrugated pipe is arranged inside the compensator body, and an enclosed space is formed from the compensator body to the outside of the corrugated pipe. Whether or not an internal moisture removal pipe leading out from the enclosed space formed by the compensator body and the corrugated pipe emits steam and steam emit amount are detected so as to visually determine whether the compensator body is in an accident rate or not; by detecting whether or not the internal moisture removal pipe leading out from the enclosed space formed by the compensator body and the corrugated pipe emits steam and the steam emit amount, whether or not leaked steam exists in a heat insulation layer is judged for troubleshooting one by one; the compensator is simple in structure and convenient to use, leakage points can be checked quickly, and the problem that the leakage points can only be found by repeatedly troubleshooting all pipe fittings and pipes to cause waste of manpower and money is avoided.
Description
Technical field
The present invention relates to a kind of compensator, specifically relate to a kind of steel sleeve steel direct-buried internal pressure type compensator with leak source examination device for steam heat distribution pipe network.
Background technique
At present, the compensator generally using is made up of the annex such as bellows, end pipe and outer protecting shell that forms its operative body, and it is effective dilatation of utilizing bellows to absorb pipeline by the size distortion former thereby that produce such as expand with heat and contract with cold.And in steam pipe system, compensator is more cracky of other pipe fittings relatively, it is opened suddenly except steam cock the undesirable element impacts such as all standing, Rig up error, geological environment, the Material Strength of bellows of compensator own is poor, and corrosion-resistant, antifatigue number of times are limited etc. becomes its easily damaged main cause of leaking.But compensator, after steel sleeve steel insulation antiseptic, once leak, is difficult to discover, and conventionally need to just can find leak source through investigating repeatedly each pipe fitting and pipeline, exhausts the people and drains the treasury.
Summary of the invention
In view of the problem that prior art exists, the object of the invention is to provide a kind of steel sleeve steel direct-buried internal pressure type compensator with leak source examination device for steam heat distribution pipe network; It has or not the running state of steam or steam flow size investigation compensator body by observing each outlet pipe, determine and take which kind of measure, guarantees pipeline safety operation.
To achieve these goals, the technical solution adopted in the present invention is the steel sleeve steel direct-buried internal pressure type compensator with leak source examination device, and it comprises: compensator body, oversheath pipe and reinforcing sleeve; Compensator body is provided with oversheath pipe outward, and oversheath pipe is provided with reinforcing sleeve outward; Between compensator body and oversheath pipe and between oversheath pipe and reinforcing sleeve, form annular space, in compensator body, be provided with bellows, compensator body to bellows outside is confined space; It is characterized in that: it also comprises: outer humidity discharging pipe and interior humidity discharging pipe; Interior humidity discharging pipe inserts in compensator body by the hole matching with interior humidity discharging pipe on compensator body, and be fixed on compensator body, described outer humidity discharging pipe inserts by the hole matching with outer humidity discharging pipe on oversheath pipe and reinforcing sleeve in the toroidal cavity of compensator body and the formation of oversheath pipe, and on fixing outer reinforcing sleeve, described interior humidity discharging pipe box is loaded in outer humidity discharging pipe; Between interior humidity discharging pipe and outer humidity discharging pipe, be fixed with ripple ring flat-plate.
Described interior humidity discharging pipe is greater than zero to the distance of bellows.
Described interior humidity discharging pipe external diameter is less than the internal diameter of outer humidity discharging pipe.
The invention has the advantages that: it forms by compensator body and bellows the interior humidity discharging pipe that confined space draws and whether emit vapour, emit vapour amount size by detecting, and intuitively definite compensator body whether in accident condition; Forming by compensator body and oversheath pipe the outer humidity discharging pipe that non-confined space draws and whether emit vapour, emit vapour amount size by detecting, and judging the steam that whether has leakage in thermal insulation layer, doing and investigate one by one; It is simple in structure, easy to use, can be very fast be checked through leak source, avoid just finding leak source, the problem exhausting the people and draining the treasury through investigating repeatedly each pipe fitting and pipeline.
