Изобретение относитс  к машиностроению и может быть использовано нри соединении трубопроводов дл  перекачки и транспортировани  жидкой и газообразной среды, например хладагентов.The invention relates to mechanical engineering and can be used at pipeline connections for pumping and transporting liquid and gaseous media, such as refrigerants.

Известное устройство дл  соединени  трубопроводов , содержащее штуцер, ниппель и накидную гайку, позвол ет соединить трубы только дл  прохождени  одной фазы среды, например газообразной, а дл  прохождени  другой фазы, например жидкой, необходимо применение параллельного трубопровода с дополнительным соединением трубопроводов, что повышает металлоемкость соединени .The known device for connecting pipelines, comprising a fitting, a nipple and a cap nut, allows connecting the pipes only for the passage of one phase of the medium, for example gaseous, and for the passage of another phase, for example, liquid, it is necessary to use a parallel pipeline with an additional connection .

Дл  уменьшени  металлоемкости соединений трубопроводов в предлагаемом устройстве штуцер и ниппель выполнены с продольными отверсти ми и соединены с наружным и внутренним трубопроводами.In order to reduce the metal consumption of the pipe joints in the proposed device, the fitting and nipple are made with longitudinal holes and are connected to the external and internal pipelines.

На чертеже изображено предлагаемое устройство , разрез.The drawing shows the proposed device, the cut.

Устройство содержит штуцер 1, накидную гайку 2, прокладку 3, ниппель 4, продольные отверсти  5.The device includes a fitting 1, a cap nut 2, a gasket 3, a nipple 4, longitudinal holes 5.

К ниппелю и штуцеру приваривают внутренние и наружные трубы трубопроводов.Internal and external pipelines are welded to the nipple and fitting.
