Abstract
The utility model relates to a steel-in-steel directly-buried internal-pressure type compensator with a leakage point investigation device. The compensator comprises a compensator body, an outer protective casing and a reinforcing casing; the outer protective casing is arranged outside the compensator body and the reinforcing casing is arranged outside the outer protective casing; annular spaces are formed between the compensator body and the outer protective casing and between the outer protective casing and the reinforcing casing; a corrugated pipe is arranged on the compensator body and the space from the compensator body to the outside of the corrugated pipe is airtight. The compensator is characterized by further comprising an outer moisture removal pipe and an inner moisture removal pipe, wherein the inner moisture removal pipe is inserted into the compensator body via a hole which is formed in the compensator body and matched with the inner moisture removal pipe, and fixed on the compensator body, while the outer moisture removal pipe is inserted into the annular cavity formed by the compensator body and the outer protective casing via holes which are formed in the outer protective casing and the reinforcing casing and matched with the outer moisture removal pipe and fixed on the outside reinforcing casing; the inner moisture removal pipe nested in the outer moisture removal pipe; a corrugated annular plate is fixed between the inner moisture removal pipe and the outer moisture removal pipe.
Description
Technical field
The utility model relates to a kind of compensator, specifically relates 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 purpose of this utility model is that a kind of steel sleeve steel direct-buried internal pressure type compensator with leak source examination device for steam heat distribution pipe network will be provided; 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 technological scheme that the utility model adopts 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 utility model has the advantage of: 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.
