Description

Известны цанговые соединени  гладких труб. Однако такие соединени  не обеспечивают необходимой герметичности.Collet joints of smooth tubes are known. However, such connections do not provide the necessary tightness.

При применении описываемого соединени  герметичность достигаетс  тем, что труба обжимаетс  цангой на цилиндрическом штуцере, введенном во внутрь трубы в месте обжи.ма. Число зубьев цанги и зазор между ними определ ютс , исход  из допуска на толщину стенки трубы и зазора между зубь ми.When using the described connection, leaktightness is achieved by the fact that the pipe is crimped with a collet on a cylindrical fitting inserted into the inside of the pipe in the place of the bead. The number of collet teeth and the gap between them are determined based on the tolerance of the pipe wall thickness and the gap between the teeth.

На фиг. 1 изображено описываемое соединение; на фиг. 2- разрез по А-А.FIG. 1 depicts the described compound; in fig. 2 - section along the AA.

Цанговое соединение гладких труб состоит из цилиндрического штуцера /, ввертываемого в корпус 2, например, испытательного пресса , разрезной цанги 3, конического кольца 4 и накидной гайки 5.The collet joint of smooth pipes consists of a cylindrical nozzle / screwed into the body 2, for example, a test press, a split collet 3, a conical ring 4 and a cap nut 5.

Тонкостенна  трубка 6, проход ща  испытани  на прочность, плотность и герметичность, одеваетс  на гладкий отросток 7 штуцера / до упора в плоскость 8, после чего гайка 5 навинчиваетс  на резьбовой конец 9 корпуса 2. При этом комическое кольцо перемещаетс  влево и, взаимодейству  с конической поверхностью 10 цанги 3, сжимает последнюю . Зубь  /7 цанги 3 плотно обжимают трубку 6 на щтуцере Л причем зоны сжати  в металле стенки 12 трубки 6 от соседних зубьев 11 перекрывают друг друга, Создава  надежное уплотнение. Количество зубьев 11 цанги 3 выбира,етс  пр мо пропорционально допуску на толщину стенки 12 трубки 6 и обратно пропорционально величине допустимого зазора между зубь ми //.The thin-walled tube 6, tested for strength, density and tightness, is put on the smooth process 7 of the choke / until it stops in the plane 8, after which the nut 5 is screwed onto the threaded end 9 of the housing 2. In this case, the comic ring moves to the left and interacts with the conical surface 10 collet 3, compresses the latter. The tooth / 7 of the collet 3 tightly compresses the tube 6 on the clamp L and the zone of compression in the metal of the wall 12 of the tube 6 from the adjacent teeth 11 overlap, creating a reliable seal. The number of teeth 11 of the collet 3 is chosen directly proportional to the tolerance on the wall thickness 12 of the tube 6 and inversely proportional to the size of the allowable gap between the teeth //.

Описываемое соединение позвол ет упростить методику проведени  испытаний тонкостенных труб, повысить примен емые давлени , увеличить количество циклов при одновременном сокращении времени испытаний и уменьшить расход уплотнительных материалов, напри iep резины или пластмасс.The described joint allows us to simplify the test procedure for thin-walled pipes, increase the applied pressures, increase the number of cycles while reducing the test time and reduce the consumption of sealing materials, for example, iep rubber or plastic.
