Spherical double suspension wide hook rapid pipe joint

Abstract

The sphere double hangs the width ditch pipeline connection part, locks between the handle or the long hook and the gallows spacing after the introduction vice- (15), the suspension hook in own plane of symmetry two sides establishments hook (5), the seal packing collar radial direction lateral section for has the relative smaller aperture (4), assumes cavity body and spring-loaded seal tongue which incompletely seals up (3) isostructuralism, improved the fast attachment operation, increased the joint stability; To is sealed the pressure and the seal packing collar own elastic combination, establishes the seal to distort with is sealed the medium pressure the relation; Retains the shut-down condition by become estranged the coordination to release flows the channel; Sealed the tongue to enhance the establishment seal condition movement sensitivity and the reliable degree. Causes the seal with to divulge a pair of mutually contradictory function, harmoniously melts into the identical seal packing collar in the structure, thus easily realized had the pressure seal, not pressed from releases, to sealed the part the special seal request. Plan idea ingenious reasonable, structure precise simple compact, the manufacture and the use very is all convenient.

Description

technical field

[0001] The invention belongs to pipeline connecting parts, and mainly relates to a structural scheme for improving the working performance of joints. Background technique

[0002] As is well known to the public, quick joints for pipelines with spherical couplings can meet the needs of non-linear pipeline connections, and are indispensable connecting components in long-distance or non-fixed pipeline connections. However, the stability of the connection is insufficient, and the operation is not convenient enough, which often affects the rapid and reliable establishment of the connection; it cannot meet the specific requirements of sealing in the working state and timely leakage after the working state is released. If the sprinkler irrigation pipeline needs to be moved or managed during or after use, it is necessary to release the connection between the pipeline fittings. At this time, the accumulated water in the pipeline tends to leak concentratedly at the jo...

[0018] The present invention will be further described below in conjunction with drawings and embodiments.

[0019] The meanings represented by the numbers in the accompanying drawings: 1 long hook 2 bowl tube 3 sealing ring tongue 4 annular opening 5 hook head 6 pressure chamber 7 ring body 8 sealing groove 9 ball tube 10 short hook 11 bracket 12 hook hinge shaft 13 Hanging ring 14 ring hinge pair 15 limit pair 16 long hook hinge shaft 17 lock handle 18 handle hinge shaft s-lock distance

[0020] The first embodiment, as shown in Figures 1-4, 6 and 9, is a spherical double-hung wide-hook pipe quick connector for sprinkling irrigation pipes with a diameter of 76mm. Its overall dimensions are 305×220×142mm and weigh about 2kg. - Within 3 seconds, complete the full assembly or disassembly operation required for a joint connection.

[0021] The joint structure of this example is basically consistent with the existing spherical double-hook pipe quick joint, that is, the two parts...
