Abstract
The utility model relates to a pipe fitting sealing joint, particularly a locking casing type sealing joint. The locking casing type sealing joint solves the problem of height sealing. The locking casing type sealing joint comprises a joint body, an outer case nut, and a locking case. The joint body and the outer case nut are in thread engagement. The locking case is positioned between the joint body and the outer case nut. An inner wall at the connection end of the joint body is provided with a lug boss, and is formed with an end surface. One end of the outer case nut is provided with a lug boss, and is formed with a ring. The locking casing type sealing joint is characterized in that the lug boss point of the inner wall at the connection end of the joint body is provided with a sealing ring used for pipeline joints.
Description
This reality has the novel pipe joint that relates to, and refers in particular to a kind of personality card shell type SEALING FITTING that the steel pipe pipeline connects that is used for.
The existing FERRULETYPE sealed type joint that is mainly used in the connection of steel pipe road, cap nut, cutting ferrule and fittings body are arranged, steel pipe inserts fittings body during use, tighten cap nut, cap nut promotes cutting ferrule and moves ahead, cutting edge on the cutting ferrule embeds outer wall of steel pipe, form peripheral sealing surface, cutting ferrule external diameter, the fittings body conical surface also form one linear sealing simultaneously, thereby make it sealing, but this structure, because pipe workpiece quality, installation method and the factor of structure own, often occur poorly sealed phenomenon in the use, can't satisfy the occasion that high sealing requires.
The purpose of this utility model provides a kind of FERRULETYPE SEALING FITTING of high-seal.
The purpose of this utility model is achieved in that the FERRULETYPE SEALING FITTING, it comprises fittings body, cap nut and cutting ferrule, fittings body and cap nut are thread engagement, cutting ferrule is therebetween, fittings body connecting end inwall is provided with boss and forms end face, one end of cap nut is provided with boss and forms a ring, it is characterized in that: the place is provided with seal ring in fittings body connecting end inwall boss.
Above-mentioned design after pipe fitting inserts, forms the end face contact, not only plays the end face seal effect, also can play position-limiting action; And the setting of seal ring makes between pipe fitting and the seal ring end face, guarantees further to fit tightly, and has formed one new end face seal again, improves the property examined of sealing greatly, has reached the effect of high-seal.
Below by drawings and Examples the utility model is described further again.
Fig. 1 is the utility model structural representation;
Fig. 2 is the local A enlarged view of Fig. 1;
As shown in the figure: the utility model is made up of fittings body 1, cap nut 2, cutting ferrule 3 and seal ring 4, fittings body 1 is a thread engagement with cap nut 2, cutting ferrule 3 is therebetween, seal ring 4 is positioned at fittings body 1, fittings body 1 connecting end has a boss 5, and this boss 5 contacts with seal ring 4, plays a part spacing dual with sealing, after pipe fitting 6 inserted fittings body 1, its end face and seal ring 4 were fitted.Tighten cap nut 2, because of cutting ferrule 3 is provided with cutting edge 7, move ahead and close up when cutting ferrule 3 acts at cap nut 2, make the outer wall 7 of the cutting edge 7 embedding pipe fittings 6 of cutting ferrule 3, form peripheral sealing surface one, and continue to promote pipe fitting 6 and move ahead, pipe fitting 4 end faces and seal ring 4 are fitted tightly, form one new end face seal again.Under the two seals condition, the utility model has reached the purpose of design of high-seal.
