In figure: 100, pipe fitting; 1, fastening piece; 11, bulb; 2, connecting tube; 201, sticking part; 202, accommodating part; 21, spacer ring; 3, clamp ring; 31, bore a hole; 32, movable chamber; 33, collar; 4, seal ring; 41, circle body; 5, movable sheath; 51, inclined-plane; 52, annular gear mouth.
Embodiment
A kind of novel pipe fitting connection set as shown in Fig. 1 ~ 2, for connecting the end of two pipe fittings 100, comprise two fastening pieces 1 and coaxial connecting tube 2, two clamp ring 3, two seal ring 4, two movable sheath 5 arranged, the diameter of this connecting tube 2 inwall is that cascade increases by the middle part of connecting tube 2 to the two ends of connecting tube 2, this connecting tube 2 comprise for pipe fitting 100 of fitting sticking part 201 and with pipe fitting 100 away from accommodating part 202, accommodating part 202 is connected to the outboard end of sticking part 201, and two seal ring 4 one_to_one corresponding are placed in two accommodating parts 202; Two clamp rings 3 are fixed in the outboard end of accommodating part 202 respectively, have the perforation 31 that the radial direction along this clamp ring 3 extends in clamp ring 3, the medial extremity (i.e. one end of close pipe fitting 100) of perforation 31 is through with one along the axially extended movable chamber 32 of clamp ring 3; Two movable sheaths 5 are located at the outboard end side of two seal rings 4 respectively, and the medial extremity of movable sheath 5 stretches in accommodating part 202, and the outboard end of movable sheath 5 is set to inclined-plane 51, and stretches into movable chamber 32; Two fastening piece 1 one_to_one corresponding insert in the perforation 31 of two clamp rings 3, and support mutually with the inclined-plane 51 of two movable sheaths 5 respectively.
By connecting tube 2, the end of two pipe fittings 100 can be coupled together, ensure join strength, be simultaneously cascade increase by the middle part of connecting tube 2 to the two ends of connecting tube 2 due to the diameter of connecting tube 2 inwall, therefore connecting tube 2 by formed the sticking part 201 of fitting with pipe fitting 100 and with pipe fitting 100 away from accommodating part 202, sticking part 201 is for being close to pipe fitting 100 to form stable connection, accommodating part 202 is for loading seal ring 4 and stretching into movable sheath 5, by supporting the axial thrust load and radial component that produce movable sheath 5 to inclined-plane 51 simultaneously after penetrating perforation 31 with fastening piece 1, axial thrust load makes movable sheath 5 crush seal circle 4, and then make seal ring 4 extrude pipe fitting 100, to form good sealability, radial component can make movable sheath 5 extrude pipe fitting 100, to promote join strength further.Wherein, clamp ring 3 can be affixed by welding manner with accommodating part 202.Radial component drives accommodating part 202 to extrude to pipe fitting 100 by fastening piece 1, and then drive sticking part 201 can more be close to pipe fitting 100, thus improve join strength.During use, connecting tube 2, two clamp ring 3, two seal ring 4 is set on two pipe fittings 100, is exerted a force to movable sheath 5 by the interspersed action of fastening piece 1 in perforation, is connected with the reliable sealing realizing two pipe fittings 100.
For ensureing the coaxality after two pipe fittings 100 connection, the middle part of connecting tube 2 is set to the spacer ring 21 for separating two pipe fittings 100, the end face 100 of two pipe fittings 100 can be separated by spacer ring 21, and offsets with the end face of pipe fitting 100 and realize contraposition, prevents the end contact of pipe fitting 100 and misplaces.
For preventing movable sheath 5 from getting loose in accommodating part 202, the outer weekly form of movable sheath 5 has the annular be connected with described inclined-plane 51 and keeps off mouth 52, and accordingly, described clamp ring 3 side is extended with the collar 33 keeping off mouth 52 with this annular and be slidably matched.Collar 33 can keep off in mouth 52 in annular and sliding, and movable sheath 5 crush seal circle 4 can be ordered about in this collar 33 1 aspect, also can carry out stroke limit to movable sheath 5 on the other hand.
The preferred implementation of the utility model seal ring 4 is: seal ring 4 comprises at least two circle bodies 41, is connected between adjacent circle body 41.The seal ring 4 be made up of multiple circle body 41 can lift-off seal performance, effectively prevents the water of circulation in pipe fitting 100 from leaking.
Adjust for convenience movable sheath 5 pairs of pipe fittings 100 extruding degree and or the extruding degree of movable sheath 5 pairs of seal rings 4, fastening piece 1 is screw, described perforation 31 is the tapped hole coordinated with this screw thread, when screw rotates in tapped hole, the ailhead of screw will form axial thrust load and radial component at inclined-plane 51 place.
For making screw and inclined-plane 51 be slidably matched more swimmingly and form axial thrust load and radial component, the ailhead of screw is the bulb 11 be slidably matched with described inclined-plane 51.Also can immediate roof pressure pipe part 100 after screw lock, to make pipe fitting 100 depressed deformation, this bulb 11 can prevent pipe fitting 100 drilled broken, plays again the effect increasing join strength simultaneously.
Above-mentioned mode of execution is only preferred implementation of the present utility model; can not limit the scope of the utility model protection with this, change and the replacement of any unsubstantiality that those skilled in the art does on basis of the present utility model all belong to the utility model scope required for protection.
