Цель изобретения - расширение области применения компенсатора.The purpose of the invention is the expansion of the scope of the compensator.

Эта цель достигается тем, что в компенсаторе фланцы выполнены в виде концентрично расположенных наружного 30 и внутреннего усеченных конусов,· вершины которых направлены в противоположные стороны, а мембрана прикрепле- на по наружному диаметру к большему ³ основанию наружного конуса, а по внутреннему - к меньшему основанию внутреннего конуса, при этом мембрана может быть выполнена многослойной.This goal is achieved by the fact that in the compensator, the flanges are made in the form of concentrically arranged outer 30 and inner truncated cones, the vertices of which are directed in opposite directions, and the membrane is attached on the outer diameter to the larger ³ base of the outer cone, and on the inside to the smaller the base of the inner cone, while the membrane can be multilayer.

Компенсатор содержит патрубки 1 и 2, на которых установлены фланцы в · виде концентрично расположенных наружного 3 и внутреннего 4 конусов. Мембрана 5 прикреплена по наружному диаметру к большему основанию фланца 3, а по внутреннему - к меньшему основанию конуса 4. Для повышения прочности 'мембраны она может быть выполнена многослойной.The compensator contains nozzles 1 and 2 on which the flanges are mounted in the form of concentrically arranged outer 3 and inner 4 cones. The membrane 5 is attached on the outer diameter to the larger base of the flange 3, and on the inside to the smaller base of the cone 4. To increase the strength of the membrane, it can be multilayer.

Компенсатор работает следующим образом.The compensator works as follows.

При осевой деформации трубопроводов, например, в результате теплового расширения, патрубок 1 с фланцем 3 начинает сближаться в осевом направлении с патрубком 2, при этом мембрана 5 деформируется и впадина 6 перегиба мембраны перекатывается от меньшего диаметра закрепления к больэ шему по опорным поверхностям конусов. При удалении патрубков друг от друга, процесс деформации мембран происходит в обратном направлении.During axial deformation of pipelines, for example, as a result of thermal expansion, the pipe 1 with the flange 3 begins to approach in the axial direction with the pipe 2, while the membrane 5 is deformed and the cavity 6 of the bend of the membrane rolls from a smaller fixing diameter to a larger along the supporting surfaces of the cones. When removing the nozzles from each other, the process of deformation of the membranes occurs in the opposite direction.

Claims

The invention relates to pipeline engineering and can be used to compensate for temperature axial deformations of pipelines. A compensator is known which contains concentrically located external and internal nozzles, between which a flexible element in the form of an elastic sleeve P is installed in the annular gap. The disadvantage of this compensator is the impossibility of its use in systems with significant pressure of the transported medium, since the flexible element can only be made of elastic materials due to the large magnitude and flexural deformations. Also known compensator containing pipes with flanges, on which is fixed a flexible element in the form of an annular thin-walled metal membrane 2j. The disadvantage of this compensator is the small compensating capacity, which limits its use. The purpose of the invention is to differentiate the field of application of the compensator. This goal is achieved by the fact that in the compensator the flanges are made in the form of concentrically arranged outer and inner truncated cones, the tops of which are directed in opposite directions, and the membrane is attached along the outer diameter to the larger base of the outer cone, and along the inner one to the smaller base of the inner cone, at the same time the membrane can be made multi-layered. The drawing schematically shows a compensator. The compensator contains pipes 1 and 2, on which flanges are installed in the form of concentrically located outer 3 and inner 4 cones. The membrane 5 is attached at the outer diameter to the larger base of the flange 3, and at the inner diameter to the smaller base of the cone 4. To increase the strength of the membrane, it can be made multi-layer. The compensator works as follows. When axial deformation of pipelines, for example, as a result of thermal expansion, pipe 1 with flange 3 begins to approach in axial direction with pipe 2, the membrane 5 is deformed and the membrane bending depression 6 rolls from a smaller clamping diameter and larger along the support surfaces of the cones. . When nozzles are removed from each other, the process of membrane deformation occurs in the opposite direction. Claim 1. Compensator-containing pipes with flanges, on which a flexible element is attached in a thin-wall metal membrane annular membrane, characterized in that, in order to expand the field of application, the flanges are made in the form of concentrically arranged outer and inner truncated cones, the vertices of which are directed in opposite directions, and the membrane is attached on the outer diameter to the larger base of the outer cone, and on the inner one to the smaller base of the inner cone, 2. Compensator, in. 1, which is based on the fact that the membrane is multi-layered. Sources of information taken into account during the examination 1. USSR author's certificate number 192569, cl.
