Sealing gasket is accompanied, the end face of that one end to be adjoined one another to ring flange is equipped with blind round hole, circular blind on two ring flanges
Hole forms a complete cylinder die cavity, the cylinder die cavity and the bolt hole on ring flange together with the circular vias on sealing gasket
It is coaxial and have a diameter larger than the diameter of the bolt hole, coaxially it is provided with the first cylindrical spring in cylindrical type intracavitary, described first
The both ends of cylindrical spring withstand on the both ends of the cylinder die cavity, and the connecting bolt between two ring flanges is also cross the bolt hole
With the first cylindrical spring, the second circle to connect with respective flange side surface is respectively equipped with the screw cap end and nut end of connecting bolt
Post spring.
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.
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.

Embodiment
Embodiment of the present utility model is illustrated by particular specific embodiment below, those skilled in the art can be by this
Content disclosed by specification understands other advantages and effect of the present utility model easily.
The utility model is described in further detail with reference to the accompanying drawings and examples：
As shown in Fig. 1-3, a kind of breathing pipe connecting structure, connected using a pair of ring flanges 2 between adjacent two segment pipe 1
Connecing, sealing gasket 3 is accompanied between two ring flanges 2, the end face of that one end to be adjoined one another to ring flange 2 is equipped with blind round hole,
Blind round hole on two ring flanges 2 forms a complete cylinder die cavity 4, the cylinder together with the circular vias on sealing gasket 3
Die cavity 4 is coaxial with the bolt hole on ring flange 2 and has a diameter larger than the diameter of the bolt hole, in cylinder die cavity 4 coaxially
Provided with the first cylindrical spring 5, the both ends of first cylindrical spring 5 withstand on the both ends of the cylinder die cavity 4, two ring flanges 2 it
Between connecting bolt 13 also cross the bolt hole and the first cylindrical spring 5, in the screw cap end and nut end of connecting bolt 13
