Generally speaking, the utility model The new type can effectively play the role of waterproofing and preventing pipeline expansion and contraction.

Description

A kind of compensating sealing sleeve for steam pipeline passing through the wall

technical field

The utility model belongs to the technical field of heat preservation of heat pipes, in particular to a compensating sealing sleeve for a steam pipe passing through a wall.

Background technique

The pipeline passes through the wall, well wall, etc., and a protective sleeve is installed outside the pipeline for the purpose of waterproofing - the wall casing, also known as the wall pipe. Wall bushings are generally suitable for structures where the pipe passes through the wall subject to vibration or strict waterproof requirements. After the casing part is processed, the outer wall is painted with a primer (the primer includes camphordan or cold primer oil) .

The wall casing is also used when the steam pipeline passes through the wall and the well wall. Since the steam pipe contains high-temperature and high-pressure water vapor, the wall-piercing casing of the steam pipe must have higher requirements for waterproofing and preventing pipe expansion and contraction.

Contents of the invention

The purpose of this utility model is to provide a kind of compensating sealing casing for steam pipes to pass through walls. The compensating sealing casing has simple structure, easy manufacture and installation, and has the functions of good waterproof and preventing expansion and contraction of pipelines.

The purpose of this utility model is achieved in the following way: a compensating sealing casing for a steam pipe to pass through a wall, including a bellows, a steel casing, and a sealing casing, the steel casing runs through the wall, and the steel casing A steam pipe is arranged inside, an insulation layer is arranged outside the steam pipe, a bellows is arranged on one side of the wall of the steel sleeve, and a sealing sleeve is arranged outside the bellows.

A reinforced steel sleeve is also installed on the wall.

The steel sleeve and the reinforced steel sleeve are arranged concentrically.

The insulation layer is polyurethane foam material.

The sealing sleeve is welded to the outside of the bellows in a seamless welding manner.

The beneficial effects produced by the utility model are: the utility model is provided with bellows on the steel casing, so that the steel casing has a certain telescopic function, preventing the damage of the steel casing itself, and at the same time avoiding the steel casing due to thermal expansion. The impact of cold shrinkage on the wall can play a better waterproof function. In addition, the utility model also sets a sealing sleeve on the outside of the bellows, which strengthens the protection of the bellows and improves the service life of the bellows.

detailed description

Embodiments of the utility model are further described below in conjunction with the accompanying drawings.

Example 1

As shown in accompanying drawing 1, a kind of compensating sealing casing for steam pipes passing through walls, including bellows 1, steel casing 2, and sealing casing 3, the steel casing 2 runs through the wall 4, and the steel casing 2 A steam pipe 5 is arranged inside the casing 2, an insulation layer 6 is arranged outside the steam pipe 5, a bellows 1 is arranged on one side of the steel casing 2, and a sealing casing 3 is arranged outside the bellows 1 .

A reinforced steel sleeve 7 is also installed on the wall 4 .

The steel sleeve 2 and the reinforced steel sleeve 7 are coaxially arranged.

The thermal insulation layer 6 is polyurethane foam material.

The sealing sleeve 3 is welded to the outside of the bellows 1 in a seamless welding manner.

When the utility model is in use: a compensating sealing sleeve for a steam pipe to pass through a wall, including a bellows, a steel sleeve, and a sealing sleeve. A steel sleeve is installed inside the steel sleeve, and the steel sleeve runs through the wall; a steam pipe is installed inside the steel sleeve, and a bellows is installed on the steel sleeve, and the bellows make the steel sleeve have a certain expansion and contraction function, which can ensure The steel casing will not be damaged under the action of thermal expansion and cold contraction, ensuring the stability of the steel casing; a sealing sleeve is set on the outside of the bellows through seamless welding technology, and the sealing sleeve can protect the bellows on the one hand. On the other hand, it can prevent the bellows from corroding, improve the service life of the bellows, and further enhance the working reliability of the steel casing.

Generally speaking, the utility model can effectively play the functions of waterproofing and preventing expansion and contraction of pipelines.
