Technical field

The utility model belongs to pipe technology field, more particularly to a kind of expanding pipe joint.

Background technology

Pipeline is widely used among daily production and living, in laying, pipeline often is embedded in into underground, and use soil Even concrete covering, though and a certain degree of expansion or receipts occur in the change of pipeline seasonal climate in use Contracting, wherein, for exposed pipeline road, due to lacking pining down for covering, it shrinks, swell increment is bigger, and existing Pipeline does not possess good dilation performance, causes pipeline to crack or even burst in expansion or shrinkage.In addition, at present Pipeline connection it is inconvenient, thoroughly dismounting separation is just difficult to after connection.

Utility model content

The purpose of this utility model is solve above-mentioned technical problem, there is provided a kind of breathing pipeline quick change attachment structure, adopts Certain breathing variable quantity can be born with the pipeline road of the attachment structure, avoids crack, booster, and is convenient to mount and dismount, is beneficial to Safeguard.

The technical solution of the utility model is as follows：

A kind of breathing pipeline quick change attachment structure, connected using a pair of ring flanges between adjacent two segment pipe, two ring flanges Between accompany sealing gasket, the end face of that one end to be adjoined one another to ring flange is equipped with blind round hole, the circle on two ring flanges Shape blind hole forms a complete cylinder die cavity, the cylinder die cavity and the spiral shell on ring flange together with the circular vias on sealing gasket Keyhole is coaxial and has a diameter larger than the diameter of the bolt hole, and the first cylindrical spring is coaxially provided with cylindrical type intracavitary, described The both ends of first cylindrical spring withstand on the both ends of the cylinder die cavity, and the connecting bolt between two ring flanges is also cross the spiral shell Keyhole and the first cylindrical spring, the screw cap end and nut end of connecting bolt be respectively equipped with connect with respective flange side surface Two cylindrical springs.

The sealing gasket is elastic packing packing ring, and two pieces including combination snugly into each other of the elastic packing packing ring is small Seal washer, faying face one end of every piece of small seal washer are equipped with a circle groove, and the groove and ring flange are coaxial, often The bottom land of individual groove posts one piece of annular thin backing plate, is provided with disc spring between two pieces of thin backing plates, the axis of the disc spring with it is thin Backing plate is orthogonal.

When the ring flange, which is connected bolt connection, to be fixed, first cylindrical spring and disc spring are in compressive state.

Further, the both ends of second cylindrical spring connect with the ring flange of respective end and the end face of pad respectively, The pad is enclosed on the connecting bolt.

Further, uniform intervals are set between the disc spring, and the direction of the small end face of adjacent two disc spring is opposite.

Further, the outside diameter of the disc spring is equal to the annular width of the thin backing plate.

Further, the thin backing plate is stamped to form using brass.

Further, the pillar top is hemispherical, equal rounding at the end face edge of the insertion end of each segment pipe Angle.

Further, the notch edges of the annular groove of each flange side surface upper supply tube road insertion are rounded down.

Further, the notch edges of the groove are to there is fillet.

Further, the screw tip face of the push rod bolt is hemisphere face.

The beneficial effects of the utility model：The utility model is adopted the various springs using setting and produced to discharge during pipeline breathing Raw power, effectively prevent pipeline road crack, booster.When in use, if pipeline integrally expands, the first cylindrical spring, bullet Property rubber blanket and disc spring will be compressed, while the second cylindrical spring will somewhat be discharged, to ensure the second cylindrical spring as far as possible To the contact squeeze of two ring flanges；Now elastic sealing gasket is further compressed, and its sealing is also more preferable；So as to which expansive force be released Put.When pipeline is integrally shunk, the first cylindrical spring, resilient rubbber cushion and disc spring will somewhat be discharged, while the second circle Post spring is further compressed, with as far as possible the interval ensured between two ring flanges will not increase too many and cause elastic sealing gasket Seepage occurs for place, meanwhile, being released of disc spring, axial elongation enable two pieces of small pads as far as possible when pipeline contracts and become With flange side surface be in close contact, and due to the elastic deformation of elastomeric pad itself ensure that two small pads between contact Compactness.The ingenious setting of each spring of the present utility model, when pipeline is shunk or is expanded, between each spring mutually Coordinate, not only release the load that expansion or shrinkage is brought, it is ensured that the overall compactness of pipeline connection, avoid junction from sending out Raw seepage.

In addition, the utility model realizes each segment pipe and flange using pillar and the quick-disassembly structure of small column spring cooperation Rapid-assembling/disassembling between disk, first the pillar of certain segment pipe end is axially promoted along pipeline when in use, propped up under squeezing action In post retraction duct wall, corresponding pipeline section is just inserted into inside flange side surface, and cylindrical spring discharges and pillar is headed into flange In groove (patchhole of the pillar i.e. in ring flange) in disk, pillar blocks, so as to which duct section and ring flange be connected； Push rod bolt is threaded into hole in dismounting, so as to which corresponding supporting post top is back in the tube wall of duct section, while will pipe Road section is pulled open with ring flange, is convenient to mount and dismount.

Quick-disassembly structure of the present utility model is combined with the swell-shrink characteristic structure that various springs form, and can be easy to the company of replacing at any time Connect the relative flimsiness components such as the various springs or elastic sealing gasket at place, this relative to maintenance even scrap whole segment pipe for more Add economical and practical.
