Abstract
The utility model relates to a sealing joint, which belongs to the technical field of pipe fittings. The sealing joint comprises a straight pipe section, an elbow and a locking nut which are connected with one another, wherein notches which are extended along the length direction of the straight pipe section are formed in the front end of the straight pipe section symmetrically; external threads are formed on the rear parts of the notches; annular steps are arranged on the inner wall of the front end of the straight pipe section; an outer chamfer is formed in the front port of the straight pipe section; the rear end of the locking nut is screwed on the external threads of the straight pipe section; the front end of the locking nut is provided with a closed end; a through hole is formed in the central part of the locking nut; an inner chamfer is formed in the rear port of the through hole and is in fit with the outer chamfer of the front port of the straight pipe section; the elbow comprises an insertion section and an outlet section which are communicated with each other and are vertically connected; the insertion section is inserted into the through hole of the locking nut; a ring-shaped groove is formed at the periphery of the insertion section; and an O-ring is arranged in the ring-shaped groove so as to seal the ring-shaped groove and the front end of the straight pipe section. When the sealing joint is used, the elbow is turned towards a required direction first and then the locking nut is screwed up to ensure that the port direction of the elbow is locked and the sealing state is not affected.
Description
Technical field
The utility model relates to a kind of SEALING FITTING, belongs to the pipe fittings technical field.
Background technique
Waterpipe connects and uses elbow when turning to usually; Usually adopt between elbow and the pipeline and be threaded; Be coated with raw meal belt on the straight length screw thread; After elbow was threaded into straight length screw thread certain depth, two screw threads interlock gradually were tight, thereby sealing is realized in the slit that raw meal belt tamps between two screw threads.The problem that this connection exists is, when elbow is realized sealing with straight length, can not regulate again elbow towards, continuation might cause damage to the direction Rotating bend of screwing; If to the direction Rotating bend that unscrews, then can destroy sealing and cause leakage.Adjustment outlet towards and guarantee to be difficult between the sealing satisfactory to both parties, and the fixing towards being difficult to of outlet vibrated or the influence of other extraneous factor, possibly turn to.
The model utility content
The purpose of the utility model is, overcomes the problem that exists in the existing technology, and a kind of SEALING FITTING is provided, and can regulate the fixing towards the back of outlet, can guarantee sealing again.
For solving above technical problem; A kind of SEALING FITTING that the utility model provided; Comprise interconnective straight length, elbow and locking nut, the front end of said straight length is arranged with the notch that extends along the flow development length direction, and the rear of said notch is provided with outside thread; The inwall of said straight length front end is provided with circular step, and the front port of said straight length is provided with outer chamfering; The rear end of said locking nut is screwed on the outside thread of said straight length, and the front end of said locking nut is that closed end and center portion are provided with through hole, chamfering and fit with the outer chamfering of said straight length front port in the rear port of said through hole is provided with; Said elbow comprises mutual perforation and the inserting section and the outlet section that at right angles connect; Said inserting section is inserted from the through hole of said locking nut; The periphery of said inserting section is provided with at least one annular groove, is provided with the inner wall sealing of realization of O type circle and said straight length front end in the said annular groove.
With respect to existing technology; The utility model has been obtained following beneficial effect: realize sealing through O type circle between elbow inserting section and the straight length; Before locking nut is not tightened, earlier with elbow turn to need towards, tighten locking nut again; Push down the outer chamfering of straight length front port until the interior chamfering of locking nut closed end through hole; Because the front end of straight length is provided with notch, make the front end of straight length receive inside the contraction on the inserting section of holding tightly under the external force extruding at elbow, the outlet of elbow at this moment is towards being able to locking and can not influencing sealing state.
As the preferred version of the utility model, said annular groove and O type circle are provided with two groups.Can guarantee sealing through two seals.
As the preferred version of the utility model, be provided with gasket seal between the circular step of the port of said elbow inserting section and said straight length inwall.Port and perisporium in the elbow inserting section is equipped with sealing like this, makes sealability better.
As the further preferred version of the utility model, the outlet section outer wall of said elbow is provided with taper and pulls out.

Embodiment
As shown in Figure 1; The SEALING FITTING of the utility model comprises interconnective straight length 1, elbow 2 and locking nut 5; The front end of straight length 1 is arranged with the notch 1b that extends along the flow development length direction; The rear of notch 1b is provided with outside thread 1a, and the inwall of straight length front end is provided with circular step, and the front port of straight length is provided with outer chamfering 1c; The rear end of locking nut 5 is screwed on the outside thread 1a of straight length 1, and the front end of locking nut 5 is that closed end and center portion are provided with through hole, chamfering and fit with the outer chamfering 1c of straight length 1 front port in the rear port of through hole is provided with.Elbow 2 comprises mutual perforation and the inserting section 2a and the outlet section 2b that at right angles connect; Inserting section 2a inserts from the through hole of locking nut 5; The periphery of inserting section 2a is provided with bipassage ring connected in star 2a-1, is respectively equipped with the inner wall sealing of 4 realizations of O type circle and straight length 1 front end among the annular groove 2a-1.Be provided with gasket seal 3 between the circular step of the port of inserting section 2a and straight length inwall.The outlet section 2b outer wall of elbow 2 is provided with taper and pulls out 2b-1 and be beneficial to flexible pipe and connect.
Realize sealing through O type circle 4 and gasket seal 3 between elbow inserting section 2a and the straight length 1; Before locking nut 5 is not tightened; Earlier with elbow 2 turn to need towards; Tighten locking nut 5 again, push down the outer chamfering 1c of straight length front port, because the front end of straight length is provided with notch 1b until the interior chamfering of locking nut closed end through hole; Make the front end of straight length 1 inwardly shrink down on the inserting section 2a that holds tightly at elbow receiving external force extruding, elbow outlet section 2b this moment locks and can not influence sealing state towards being able to.
Except that the foregoing description, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
