(54) СОЕДИНЕНИЕ ТРУБОПРОВОДОВ(54) PIPING CONNECTIONS

tt

Изобретение относитс к узлам и детал м машин, а более конкретно к герметичным соединени м трубопроводов , и может быть использовано в 1вобой отрасли машиностроени , преимущественно в издели х, требующих почвышенную надежность герметизации при эксплувтапии в сложных услови х, а именно при воздействии вибрации, высокой и низкой температуры, глубокого вакуума и высокого давлени , агрессивной уплотн емой среды и Щ),The invention relates to units and parts of machines, and more specifically to hermetic pipe joints, and can be used in the civil engineering industry, mainly in products that require soil-like reliability of sealing during operation under difficult conditions, namely when exposed to vibration, high and low temperature, high vacuum and high pressure, aggressive densified medium and Sch),

По основному авт. св. № 542062 исзвестно соединение трубопроводов с фланцами, между расположен ко1С цевой уплотнительный элемент с полками, взаимодействующими с кони ,ческнми внутренними поверхност ми фланцев. Полки уппотнительного элемента выполнены составными из упругой и жесткой частей, причем упруга часть одаой стороной контактирует с внутренней ксшической поверхностью фланцев, а другой - с жесткой частью уплотни-According to the main author. St. No. 542062, the connection of pipelines with flanges is known; between them is a co1C sealing element with shelves that interact with horses, and the internal surfaces of the flanges. The shelves of the reinforcing element are made up of elastic and rigid parts, with the elastic part of this side contacting the inner ksshicheskoy surface of the flanges, and the other - with the rigid part of the seal

TejbHoro элемента. На /кесткой части уплотни те Лгного элемента по периметру выполнены сквозные отверсти , обеспе- чивакацие возможность упругим част м полок работать с эффектом самоуплотнени за счет увеличени внутреннего давлени рабочего компонента tlH .TejbHoro element. Throughout the perimeter of the sealing part of the LN element, through holes are made, allowing the elastic parts of the shelves to work with the effect of self-sealing by increasing the internal pressure of the working component tlH.

Это повышает надежность герметизации соецинейи , но только частично, так как эффект самоуплотнени полностью не испо/ьзуетс . Внутреннее дав/юние рабочего компонента действует на упругую часть попки только в точечньк местах, а именно против сквозных отверстий в жесткой части уплотнительного элемента, чти не обеспечивает сплошности воздействи внутреннего давлени рабочего компонента по всему периметру,This increases the reliability of the sealing of the sociocinei, but only partially, since the self-sealing effect is not fully utilized. The internal pressure / junior of the working component acts on the elastic part of the butt only in dotted places, namely against the through holes in the rigid part of the sealing element, almost does not ensure the continuity of the internal pressure of the working component around the perimeter,

Цель изобретени - повышение надежности герметизации соединени в сложных услови х.The purpose of the invention is to increase the reliability of sealing a compound in difficult conditions.

Claims

This goal is achieved by the fact that along the perimeter of the rigid part of the flange of the sealing element on the side, the contact of the rudder with the surface of the elastic part of the shelf, are made of flat grooves, connected with through holes. Fig, 1 shows the proposed sealing element, a cut; 4ig. 2 - connection of pipelines. The joint has a packing unit 1, the shelves of which are made of elastic 2 and rigid 3 parts. The elastic part 2 shelves is one side. 4 flanges 5 are in contact with the inner conical surface 3 and flanges 3 of the other are rigid. The parts 3 of the sealing element shelf on the side in contact with the surface of the elastic part 2 of the sub, the ring grooves 6, which are connected to the through holes 7, are made. The connection of the pipelines follows the same way. When the working component is supplied to the main line after the opening 7, it fills the grooves 6, which makes it possible to increase the effect of self-sealing 2 of the joint due to the effect of the internal pressure of the working component on the elastic part 2 of the shelf completely around the perimeter against the grooves 6 on the rigid part 3 of the sealing surface 1. The introduction of additional grooves allows for a self-sealing effect entirely around the perimeter of the sealing element. Claims of pipeline connection Eve, J 542O62, characterized in that, in order to increase the reliability of sealing, along the perimeter of the flange of the flange of the sealing element on the side that contacts the surface of the elastic part of the bucket: and, ring grooves communicated with through holes are made.
