Embodiment
Like Fig. 1, shown in Figure 2; The inserting type pipe joint of the utility model mainly comprises: be provided with the jack of two tubing of can pegging graft body 1, be arranged at intrinsic seal ring 2 and gland 5; The insertion mouth 16 end inboards of said body 1 are provided with conical bore 15, and said body 1 has outside thread 9, and said gland 5 has the internal thread 10 that the outside thread with body matches; Promptly; Said body 1 is threaded through internal thread 10 and outside thread 9 with gland 5, is provided with pilot hole 17 in the said body 1, outwards is provided with seal ring 2, setting sleeve 3 and clamp ring 4 in the said pilot hole 17 successively from the lining; Said gland 5 plays a part dustproof and compresses clamp ring 4; Said seal ring 2 is processed by rubber, is provided with the closed seal ring flange 7 of annular around said seal ring 2 axle center and along the inner ring of said seal ring, when the insertion end of tubing has cut; Elasticity through said seal ring flange 7 to tubing package power and sealing ring material; Make the cut place fill up and make seal ring to be closely attached on tubing, thereby prevent the leakage of liquid or gas, be provided with groove 6 around said setting sleeve 3 axle center and along the outer diameter face of said setting sleeve; 17 of the pilot holes of said body 1 are gone up corresponding said groove 6 and are provided with the body flange 8 that is fastened on groove; Said body flange 8 is on the pilot hole face, to be that the center of circle distribute or fully closed flange with the body axle center by at least one section projection, at least one groove or the fully closed groove of said groove 6 for matching with said body flange 8, and said setting sleeve 3 is used for axially locating clamp ring 4 and seal ring 2; Said setting sleeve 3 is processed by having certain flexible material; So that said setting sleeve 3 makes a concession distortion and pass the body flange 8 that is arranged on the body inner hole surface smoothly under its elastic reaction, the body flange 8 on 17 of groove 6 and the body pilot holes on the setting sleeve 3 outer diameter faces is interlocked, thereby guarantees the axial pressure of 3 pairs of seal rings 2 of setting sleeve.In addition, can make said body flange 8 and the Placement that groove 6 is interlocked into thread connecting mode.
When tubing when pipe joint is extracted out; 3 pairs of seal rings of said setting sleeve, 2 axial applied pressures are greater than the friction between tubing and seal ring 2 endoporus; Thereby seal ring 2 can not be extracted out with tubing; Axially locating is carried out in 3 pairs of clamp rings of said setting sleeve 4, and under the extruding of said gland 5, makes clamp ring 4 be in clamped condition.Said clamp ring 4 is processed by stainless steel material; And said clamp ring 4 has locking jaw 13, thereby can prevent tubing moving axially in pipe joint; Said clamp ring 4 is provided with a fracture 11; The insertion mouth 16 end diameter of bores of said body 1 are greater than clamp ring 4 outer diameters, and the insertion mouth 16 end inboards of said body 1 are provided with conical bore 15, and the tubing of said gland 5 inserts mouthful 14 the inners and is provided with seal ring 12.When being installed on said clamp ring 4 said body 1, at first put into said clamp ring 4 in the endoporus that bodies insert mouthful 16 places, gland 5 is installed on body then; At this moment, the thrust that the tubing of said gland inserts mouthful 14 inner side ends makes the medial movement of clamp ring 4 to conical bore 15, when conical bore 15 is passed through in said clamp ring 4; Because the aperture reduces gradually; The pressure that conical bore 15 entad imposes for clamp ring 4 outer rings makes clamp ring 4 produce resiliently deformable, and fracture 11 slits of said clamp ring 4 are narrowed down gradually, and the external diameter of said clamp ring 4 diminishes gradually; When said gland 5 was shifted clamp ring 4 onto conical bore 15, said clamp ring was assembled in the pilot hole 17 just.When assembling was accomplished, said clamp ring 4 was in complete positioning and fixing state under the effect of the inner side end of the end face of setting sleeve 3 and gland 5.
And; The tubing of said gland 5 inserts the tube outer diameter that mouthful 14 internal diameters connect greater than the need that insert in it; The tubing of said gland 5 inserts the tubing insertion mouthful 14 end diameter of bores of mouthful 14 terminal diameter of bores less than said gland 5, so that tubing tightly fits in the seal ring 12 of said gland 5.Therefore, when being embedded in pipe-line system concrete layer or being used in rugged environment, work to prevent that sand and dust and earth from getting into.
The installation and removal of tubing are specific as follows: tubing is installed, that is, and when being plugged in pipe joint to tubing, as long as pushing away inward gently in the socket of tubing insertion tube joint; During dismounting tubing, turn on said gland 5 earlier, extract tubing gently then; At this moment, the clamp ring 4 of chucking tubing is inserted mouthful 16 ends with tubing to the big body of diameter and is moved, and diameter becomes big gradually under self elastic reaction simultaneously; When clamp ring 4 was displaced to the endoporus of said body insertion mouthful 16 ends, said clamp ring 4 returned to original state, promptly; Tubing is thoroughly unclamped in clamp ring, and draw promptly detachable this moment with have gentle hands.The pipe joint of demolition and tubing can reuse.
