Abstract

The utility model relates to the technical field of a pipe joint, in particular to a flexible pipeline joint. The flexible pipeline joint comprises a joint sleeve and two sealing rubber rings arranged in the joint sleeve in a matching way. The flexible pipeline joint is characterized in that each sealing ring is designed to a hollow structure; capsules communicating with the cavity of the hollow rubber ring is arranged on the sealing rubber rings; liquid working mediums are filled in the capsules and the hollow sealing rubber ring; a casing body which extends out and can be used for putting the capsules is arranged at the upper part of the joint sleeve; and a gland which can be locked and can generate extrusion to the capsules when the locking is performed is arranged on the casing body; two pipelines are hermetically connected by the inflated hollow rubber ring. The flexible pipeline joint has the advantages that the disassembly and assembly are convenient, and the sealing connection is reliable.

Description

The flexible pipe joint
Technical field
The utility model relates to the pipe joint technical field, is specifically related to a kind of flexible pipe joint.
Background technique
Present all kinds of pipe joint has multiple structural type, as screw thread structure, flange arrangement, sleeve structure or the like.These pipe joints are the mode of being rigidly connected substantially, shortcoming such as when its ubiquity complex procedures, installation fee, and the pipeline that particularly is not suitable for butt joint has the situation of certain displacement amount and rotation.Flexible connection mode of the prior art is to adopt two solid O-ring seal both sides extruding in sleeve pipe and sleeve pipe basically, to inserting the seal for pipe joints ways of connecting in the sleeve pipe, the not easy-to-dismount shortcoming of the same existence of this mode.
The model utility content
The purpose of this utility model just is to provide a kind of flexible pipe joint, and it is convenient to dismounting, and it is reliable to be tightly connected.
The novel technological scheme of this reality is: the utility model comprises swagelok and is provided in two interior O-ring seals of swagelok, it is characterized in that: O-ring seal is made as hollow-core construction, and on O-ring seal, be equipped with and be connected logical capsule with the cavity of cushion rubber, be filled with liquid-working-medium in capsule and the hollow seal cushion rubber, be provided with on swagelok top and extend the housing that can put capsule, and on housing, be equipped with can lock, can produce the gland of extruding to capsule during locking.Described capsule is communicated with the oil hydraulic circuit that the back forms sealing with the hollow seal cushion rubber, and capsule itself just is equivalent to an accumulator, behind pressurized, discharges liquid-working-medium rapidly, the hollow seal cushion rubber is expanded, and the hollow seal cushion rubber of expansion connects two seals for pipe joints.
Hollow seal cushion rubber described in the utility model is made as the integrative-structure that is communicated with capsule, is simplified design like this, and capsule and hollow seal cushion rubber can be made for the special-shaped cushion rubber of one.The described liquid-working-medium that is filled in capsule and the hollow seal cushion rubber is water or oil.For design of the present utility model, also can the using gases working medium, but ordinary circumstance only is suitable for the lower occasion of pressure.The capsule that sets on the hollow seal cushion rubber of described swagelok is established and can be set to one, and the hollow cavity of this capsule while and two hollow seal cushion rubbers is communicated with, and the corresponding housing that is provided with on swagelok top is one; Perhaps the capsule that sets on the hollow seal cushion rubber of described swagelok is made as two, and each hollow seal cushion rubber connects a capsule, the corresponding housings that two storing capsules are set respectively on swagelok top, and each housing is equipped with gland respectively.The bottom of above-mentioned housing offers the installation through hole that is used to assemble capsule.
The beneficial effects of the utility model are: the utlity model has easy accessibility, the characteristics reliable, that anti-vibration performance is good that are tightly connected, and can be applicable to being connected of pipeline with certain displacement amount and rotation, and the connection of different tubing pipelines.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is that sectional view is looked on the left side of Fig. 1.
Embodiment
Shown in accompanying drawing 1,2, the utility model comprises swagelok 1 and is provided in two O-ring seals 2,3 in the swagelok 1, O-ring seal 2,3 is made as hollow-core construction, and on O-ring seal 2,3, be equipped with and be connected logical capsule 4 with the cavity of cushion rubber, be filled with liquid-working-medium in capsule 4 and the hollow seal cushion rubber 2,3, such as oil or water, be provided with the extended housing 5 that can put capsule 4 on swagelok 1 top, and on housing 5, be equipped with can lock, when locking can produce the gland 6 of extruding to capsule 4, gland 6 is hinged on the housing 5.Described capsule 4 is communicated with the oil hydraulic circuit that the back forms sealing with hollow cushion rubber 2,3, and capsule 4 itself just is equivalent to an accumulator, behind pressurized, discharges liquid-working-medium rapidly, hollow cushion rubber is expanded, and the hollow cushion rubber 2,3 of expansion is tightly connected two pipelines 7,8.
When implementing, hollow cushion rubber described in the utility model can be made as the integrative-structure that is communicated with capsule, is simplified design like this, and capsule and hollow cushion rubber can be made for the special-shaped cushion rubber of one.The described liquid-working-medium that is filled in capsule and the hollow seal cushion rubber is water or oil.For design of the present utility model, also can the using gases working medium, but ordinary circumstance only is suitable for the lower occasion of pressure.The capsule that sets on the hollow cushion rubber of described swagelok is established and can be set to one, and the hollow cavity of this capsule while and two two hollow cushion rubbers is communicated with, and the corresponding housing that is provided with on swagelok top is one; Perhaps the capsule that sets on the hollow cushion rubber of described swagelok is made as two, and each hollow cushion rubber connects a capsule, the corresponding housings that two storing capsules are set respectively on swagelok top, and each housing is equipped with gland respectively.The bottom of above-mentioned housing offers the installation through hole that is used to assemble capsule.
