Technical solution of the present utility model is: a kind of pipe joint in order to connect pipeline, comprising: be formed with expansion mouth at the pipeline joint; Sealing gasket is located between the two butt joint pipelines, and the sealing spacer has the rank portion that one day, described pipeline expansion mouth protruded, and the peripheral shape of described rank portion is matched with this expansion mouth fully and stretches into this expansion mouth, and offseting with it constitutes a sealing surface; Cover plate with the fixing described sealing gasket of the mode of double team pipeline expansion mouth and sealing gasket, runs through cover plate and sealing gasket with latch fitting during winding, is made the sealing surface packing and is reached the effect that seals fully in the pipe by the sealed pressure that produces of cover plate.
Aforesaid pipe joint, sealing face are an inclined-plane.
Aforesaid pipe joint, outer rim in sealing pad rank portion is provided with a sealing lip, this sealing lip has an elasticity multiplication of voltage portion when making fluid pass through this place, and because of pressure makes the distortion of multiplication of voltage portion, the sealing lip obtains this resiliently deformable stress and produces automatic sealing load with expansion mouth.
Aforesaid pipe joint, this elasticity multiplication of voltage portion offers a breach at the root edge of the rank of sealing gasket portion to constitute, make elasticity multiplication of voltage portion just like an elastic arm by this breach, can when it bears pressure, produce the elastic force effect of distortion, be enough to sealing lip held to make with expansion mouth self-sealing power takes place.
Aforesaid pipe joint, surface of contact at cover plate and sealing gasket, be provided with the sealing lip of a cover plate, the sealing lip makes pipe joint make this multiplication of voltage portion distortion because of the strength of locking with an elasticity multiplication of voltage portion, and make cover plate for sealing lip material obtain distortional stress and produce sealing load, and reach self-sealing effect.
Aforesaid pipe joint, this elasticity multiplication of voltage portion offers a breach at the root edge of cover plate to constitute, make elasticity multiplication of voltage portion just like an elastic arm by this breach, can when it bears pressure, produce the elastic force effect of distortion, be enough to sealing lip held with sealing gasket self-sealing power takes place.
Aforesaid pipe joint is wrapped up with yielding nonmetallic material in this metal cover plate periphery, makes to comprise that elasticity multiplication of voltage portion and cover plate for sealing lip bring into play the effect of its resiliently deformable.
Characteristics of the present utility model and advantage are: pipe joint of the present utility model is used for the pipe arrangement of pipeline, particularly two pipelines are coupled together, the expansion mouth that comprises the pipeline connecting end, sealing gasket between two pipeline expansion mouths, and in order to the fixing cover plate of sealing pad, wherein, the sealing spacer has the rank portion that one day, the pipeline expansion mouth protruded, the shape of rank portion is matched with this expansion mouth fully and stretches into this expansion mouth, the preferably is that this rank portion and expansion mouth are an inclined-plane and offset each other and become a sealing surface, makes the sealing surface packing by the sealed pressure that produces of cover plate and reach in the pipe effect of sealing fully when winding.
