Description

На чертеже изображен общий вид быс- троразьемного соединени трубопроводов и шлангов в разрезе.The drawing shows a perspective view of a quick-disconnect connection of pipelines and hoses.

На левой половине чертежа изображено соединение в расстыкованном .состо нии . На правой половине чертежа изображено соединение в состыкованном состо нии.The left half of the drawing shows the connection in undocked state. The right half of the drawing shows a docked connection.

Быстроразъемное соединение состоит из присоедин емой 1 и ответной 2 частей,The quick disconnect connection consists of the attached 1 and reciprocal 2 parts,

Присоедин ема часть 1 выполнена в виде ниппел , имеющего канавку 3 дл размещени элементов фиксации и уплотн емую поверхность 4. Ответна часть 2 содержит ниппель 5 и втулку 6 с уплотни- тельным элементом, выполненным в виде кольца 7 круглого сечени . Внутри втулки 6 расположен клапан 8, поджатый пружиной 9 до упора в уступ 10 втулки 6. В боковых радиальных отверсти х втулки 6 размещены элементы фиксации - шарики 11, которые опираютс на цилиндрическую поверхность 12 клапана 8. На наружной поверхности втулки 6 перемещаетс муфта 13, поджата пружиной 14. Дл ограничени хода муфты 13 имеетс кольцо 15.The attachment part 1 is made in the form of a nipple having a groove 3 for accommodating the fixing elements and a sealing surface 4. The response part 2 comprises a nipple 5 and a sleeve 6 with a sealing element made in the form of a circular cross-section ring 7. A valve 8 is located inside the sleeve 6, pressed by the spring 9 until it stops against the ledge 10 of the sleeve 6. In the lateral radial holes of the sleeve 6 are placed locking elements - balls 11, which are supported on the cylindrical surface 12 of the valve 8. On the outer surface of the sleeve 6 the sleeve 13 moves. preloaded by spring 14. To limit the travel of clutch 13, a ring 15 is provided.

Клапан 8 имеет цилиндрическую уплотн емую поверхность 16, котора по диаметру одинакова с уплотн емой поверхностью 4 присоедин емой части 1.The valve 8 has a cylindrical sealing surface 16, which is the same in diameter with the sealing surface 4 of the connecting part 1.

На поверхности 12 имеютс радиальные отверсти 17 дл прохода среды.Поверхность 12 по диаметру выполнена меньше внутреннего диаметра уплотнительного кольца 7.Radial openings 17 are provided on the surface 12 for the passage of the medium. The diameter of the surface 12 is smaller than the inner diameter of the o-ring 7.

В муфте 13 имеетс канавка 18 с конусной поверхностью дл размещени шариков 11 в процессе стыковки.In the sleeve 13 there is a groove 18 with a tapered surface for accommodating the balls 11 during the mating process.

Соединение работает следующим образом .The connection works as follows.

При стыковке присоедин емой части 1 к ответной части 2 происходит отжатие клапана 8 от уступа 10 втулки 6. При этом шарики 11. перекатыва сь по поверхности 4 и наружной поверхности присоедин емой части 1. перемещаютс по радиальным отверсти м в канавку 18 муфты 13 до тех пор, пока канавка 3 не окажетс против шариков 11. Под действием конусной поверхности канавки 18 шарики 11 западают в канавку 3 иWhen docking the connecting part 1 to the mating part 2, the valve 8 is depressed from the ledge 10 of the sleeve 6. In this case, the balls 11. rolling over the surface 4 and the outer surface of the connecting part 1. are moved along the radial holes into the groove 18 of the sleeve 13 until until the groove 3 is against the balls 11. Under the action of the conical surface of the groove 18, the balls 11 fall into the groove 3 and

QUICK DISCONNECTION PIPELINE

HOSES, consisting of radially sealed attachable and reciprocal parts, the last of which contains a sleeve with radially movable locking balls and a sealing element,

spring-loaded clutch and valve, characterized by a closed clutch 13 using a spring 14.

The surface 4 of the attached part 1 is sealed due to radial deformation

rings 7.

The connecting part 1 is docked with the mating part 2 to ensure their tightness and fixation. The connection is disconnected by depressing the sleeve 13 to

0 until the groove 18 is against the balls 11. Under the action of the spring 9, the balls 11 are moved from the groove 3 of the connecting part 1 along the radial holes of the sleeve b into the groove 18. The connecting part 1 is unlocked and expelled by the spring 9 through valve 8 from reciprocal i 2, wherein valve 8 is moved all the way into ledge 10.

The sealing of the internal cavity of the outlet part 2 is provided due to the radial deformation of the sealing ring 7 when it is mated with the valve 8 over the surface 16.

The design of the connection has one sealing element, does not require accurate execution of the axial dimensions of the valve and the connected part, and provides a normalized radial reformation of the sealing ring while ensuring

0 connection speed. The ring 7 seals two cylindrical surfaces: constantly in the bore 6 and alternately the surface 16 of the valve I.

Tests of the proposed connection confirmed the simple, convenient and reliable connection of the units to the pneumatic system of the apparatus and the preservation of its operability for 7000 cycles of docking-undocking, which exceeds the required number of connections of the units during the service life by more than three times.

Moreover, the valve of the counterpart is made of interacting fixing balls of the sleeve of the counterpart and in the open state of the joint is sealed in the radial direction, while the sealing surfaces of the valve and the connected part are made of the same diameter
