Description

one
The invention relates to pipeline engineering and can be used as a compensating device in pipelines for transporting various media, for example, for liquefied gas pipelines.
An axial compensator is known, comprising an outer and an inner nozzle, an elastic membrane supported on hinged segmented plates.
The disadvantage of the compensator is the small amount of axial movement, which is limited by the supporting plates.
The closest to the invention to the technical essence is Ase. a compensator including external and internal nozzles, an elastic Q sleeve attached to the nozzles
and having a broken 23 The disadvantage of the known compensator is its insufficient tightness and the presence of a large force on the bending surface of the elastic sleeve, which can lead to its mechanical destruction.
The purpose of the invention is to increase the reliability and durability of the compensator.
The goal is achieved by the fact that a chamber is formed on the internal nozzle, which forms a cavity of variable volume filled with a fluid medium and communicates with the chamber by means of check valves, one valve connecting the sleeve cavity to the camera, and the other connecting the chamber to the sleeve cavity .
The drawing shows the proposed device.
The pipe compensator consists of a nozzle 1 and an expansion nozzle 2, telescopically entering one into another, an elastic sleeve 3 and a chamber k, formed on the inner nozzle 1 and forming
with a flexible sleeve, a cavity 5 filled with liquid or gas and communicating with chamber k by means of check valves 6 and 7 with opposite flow for a liquid or gas, seals 8 placed on the outer side of chamber k, hermetically moving along the inner surface of elastic hukawa 3. Each the pipe has a travel stop 9 and 10.
The compensator works as follows
When a cold product enters the pipeline, the nozzle 1, which undergoes temperature changes in length, moves with the chamber t relative to the expansion nozzle 2, reducing the volume of the cavity 5 of the elastic sleeve 3. The decrease in the volume of the cavity 5 of the elastic sleeve 3 leads to an excess of pressure, and the excess liquid or gas moves from the cavity of the elastic sleeve 3 through the non-return valve 6 into the cavity of the chamber 4, maintaining a constant pressure in the cavity 5 of the elastic sleeve 3. Moreover, this pressure is significant It is less than the pressure of the product being transported, but sufficient to give the desired shape to the bending of the elastic sleeve.
When the nozzle 1 and the chamber 4 are displaced relative to the elastic sleeve 3 along its inner surface, the seal 8 slides, the section, the pipeline cavity from the cavity 5 of the elastic sleeve 3
In the event of an increase in the temperature in the pipeline 1 and the movement of the chamber 4. In the opposite direction, the liquid or gas from the chamber 4 through the check valve 7 will move into the cavity 5 of the elastic sleeve 3.
The use of a compensator makes it possible to prevent the high pressure of the transported medium from affecting the bending surface of the elastic sleeve, its destruction and the avalanche flow of the product into the atmosphere, which generally improves the reliability and durability of pipeline compensators.
