Description

Изобретение относитс  к типам соединений криогенных трубонроводов, .работающих в услови х глубокого разрежени , и может быть исиользовано в промышленных и эксперил;ентальных установках, имитирующих услави  космоса, в частности глубокое разрежение и низкие те.мпературы.The invention relates to types of connections of cryogenic pipelines operating under conditions of deep dilution, and can be used in industrial and experimental installations that simulate space exploration, in particular, deep vacuum and low temperatures.

Известны соединени  трубопроводов, преимущественно криогенных систем, включающие стакан, крепежные и уплотнительные элементы и фланцы.Connections to pipelines, mainly cryogenic systems, are known, including glass, fastening and sealing elements, and flanges.

Однако известное соединение трубопроводов допускает проса чиванйе среды (криогенной жидкости) в область стыка труб и не гарантирует его гер.метичНость, так как при захолаживалии соединени  возможно его разуплотнение за счет осевой температурной усадки элементов конструкции.However, the known connection of pipelines permits the penetration of the medium (cryogenic liquid) into the area of the pipe joint and does not guarantee its tightness, since when the joint is cooled down, its decomposition is possible due to axial temperature shrinkage of the structural elements.

Дл  иовыщени  герметичности соединени  крепежные элементы .расположены непосредственно в полости ста.кана и выполнены из материала , коэффициент линейного расширени  которого больше коэффициента линейного расширени  материала стакана.In order to improve the tightness of the joint, the fasteners are located directly in the cavity of the steel and are made of a material whose linear expansion coefficient is greater than the linear expansion coefficient of the glass material.

На чертеже изоорлжено предлагаемое еееди ней и е тр убо п ровод ов.The drawing isoorlzheno proposed her unit and e tr ubodov wires.

К т.рубодроводу / и фланцу 2 приварен стакан 3. Крепежные элементы 4 расположены неносредственно в полости стакана 3 иA cup 3 is welded to the conduit / and flange 2. The fastening elements 4 are located directly in the cavity of the glass 3 and

выполнены из материала, коэффициент л;1нейного расширени  которого больше коэффициента линейного расширени  материала стакана .made of a material whose coefficient l; 1 of the current expansion of which is greater than the linear expansion coefficient of the material of the glass.

Гермет}1зац11  фланцев 2 и J осуществл етс  за счет уплотнени  5, а герметизаци  крепежных элементов - за счет уплотнений 7.Hermet} 1ac11 flanges 2 and J is carried out by sealing 5, and sealing of fasteners by sealing 7.

При подаче в трубопровод крлоге)1ной жидкости захолаживаютс  стакан 3, зплотне1 и  6 и 7 и крепежные элементы 4. Вследстие того, что : материала крепежных элементов коэффициент линейного расширени  больше, чем коэффициент линейного расширени  материала стакана, уплотнени  6 и 7 при захолаживании дополнительно поджимаютс  за счет линейной усадки крепежных элементов.When liquid is fed into the pipeline (clogging) of the liquid, the cup 3 is closed, 1 and 6 and 7, and the fasteners 4. Due to the fact that: the material of the fasteners linear expansion coefficient is greater than the linear expansion coefficient of the glass material, seals 6 and 7 are additionally tightened during cooling down due to linear shrinkage of fasteners.

Предмет изобретени Subject invention

Соединение трубонроводов, преимущественно криогенных систем, включающее стакан, крепежные и уплотнительные элементы и фланцы, отличающеес  тем, что, с целью повышени  герметичности соединени , кренежные элементы располол ены неносредственно в полости стакана и выполнены из .материала, коэффициент ли 1ейного расширени  которого больше коэффициента линей;шго расширени  материала стакана.The connection of pipelines, mainly cryogenic systems, including glass, fastening and sealing elements and flanges, is characterized in that, in order to increase the tightness of the connection, the cutting elements are arranged directly in the cavity of the glass and are made of a material whose linear expansion coefficient is greater than the linear coefficient ; expanding the material of the glass.
