Description
(54) СОЕДИНЕНИЕ ТРУБОПРОВОДОВ(54) PIPING CONNECTIONS
Изобретение относитс к арматурным устройствам и может быть использовано в различных системах дл герметичного соедщнени агрегатов и трубопроводов .The invention relates to reinforcement devices and can be used in various systems for the hermetic connection of units and pipelines.
Известна соединительна арматура, содержаща ниппель с внутренней конусной уплотнительноП поверхностью, гайку и штуцер с деформируемым уплотнительным элементом в виде усеченной конусной обечайки со свободной кромкой , котора имеет при вершине более острый угол, чем уплотнительна поверхность ниппел .Known fittings containing a nipple with an inner conical sealing surface, a nut and a fitting with a deformable sealing element in the form of a truncated conical shell with a free edge, which has a sharper angle at the top than the sealing surface of the nipple.
Недостатками известной соединительной арматуры вл ютс сравнительно невысока жесткость и прочность деформируемого элемента, который в услови х действи т желых гидроударных, вибрационных и температурных нагрузок испытывает значительные знакопеременные деформации, вызывающие относительное перемещение состыкованных друг с другом уплотнительных поверхностей штуцера и ниппел , что приводит к нарушению герметичности соединени .The disadvantages of the known connecting reinforcement are the relatively low stiffness and strength of the deformable element, which under the conditions of severe hydropercussion, vibration and temperature loads experiences significant alternating deformations, causing relative movement of the fitting and nipple joints connected to each other, which leads to leakage compounds.
Наиболее близким по технической сущности к изобретению вл етс соединение трубопроводов, содержащееThe closest in technical essence to the invention is the connection of pipelines containing
штуцер и ниппель, заканчиваюи1иес взаимодействующими между собой наконечниками с коническги-ш уплотни тельными поверхност ми разной конусности , скрепленные гайкой 2.fitting and nipple, terminating with interacting tips with taper sealing surfaces of different taper, fastened with a nut 2.
Недостатком этой арматури вл етс отсутствие деформируемого уплотнительного элемента, что приводит к неплотному прилеганию стыкуемых по10 верхностей друг к другу и в результате к ухудшению герметичности соединени .The disadvantage of this reinforcement is the absence of a deformable sealing element, which leads to a loose fit of the joined surfaces to each other and, as a result, to a deterioration of the tightness of the joint.
Цель изобретени - повышение The purpose of the invention is to increase
15 прочности и герметичности соединени в услови х гидроударных, вибрационных и температурных нагрузок.15 strength and tightness of the joint under conditions of hydrostatic, vibration and temperature loads.
Поставленна цель достигаетс тем, что наконечник ниппел выполнен The goal is achieved by the fact that the tip of the nipple is made
20 в виде скрепленных между собой обечайки и упругого кольца, образующих со стенкой ниппел замкнутую полость, причем в стенке ниппел выполнено отверстие, соедин ющее замкнутую полость с внутренней полостью трубо25 провода .20 in the form of a shell and an elastic ring bonded to each other, forming a closed cavity with the nipple wall, with a hole in the wall of the nipple connecting the closed cavity with the internal cavity of the pipe.
Такое конструктивное решение повышает прочность деформируемого уплотнительного элемента и обеспечи30 вает герметичность соединени в усSuch a constructive solution increases the strength of the deformable sealing element and ensures the tightness of the joint in
