Embodiment
Novel pipe fitting connection set as shown in Figure 1, for connecting the end of two pipe fittings 100, comprise two fastening pieces 1 and the coaxial connecting tube 2 arranged, two clamp rings 3, two seal rings 4, two movable sheaths 5, 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 all with pipe fitting 100 away from accommodating part 202, conus portion 203, the diameter of conus portion 203 increases from the inside to the outside gradually, for increasing the extruding force to movable sheath 5 gradually, the outboard end of sticking part 201 connects accommodating part 202 and conus portion 203 successively, two seal ring 4 one_to_one corresponding are placed in two accommodating parts 202, two movable sheath 5 one_to_one corresponding are placed in conus portion 203, and the inwall of the outer surface of movable sheath 5 and conus portion 203 offsets, for keeping the squeezed state with conus portion 203, two clamp rings 3 are fixed in the outboard end of conus portion 203 respectively, have the axially extended perforation 31 along this clamp ring 3 in clamp ring 3, two fastening piece 1 one_to_one corresponding insert in the perforation 31 of two clamp rings 3, and offset with 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 all with pipe fitting 100 away from accommodating part 202, conus portion 203, sticking part 201 is for being close to pipe fitting 100 to form stable connection, conus portion 203 is for loading seal ring 4, movable sheath 5 can be supported after penetrating perforation 31 with fastening piece 1 simultaneously, make generation axial thrust load and the radial component of conus portion 203 pairs of movable sheaths 5, 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 conus portion 203.Radial component is the reaction force of conus portion 203 pairs of movable sheaths 5, extrudes to pipe fitting 100, and then drives sticking part 201 can more be close to pipe fitting 100, thus improves 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 31, is connected with the reliable sealing realizing two pipe fittings 100.Accommodating part 202 can be set to the cylindricality annulus of diameter equalization.
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 making movable sheath 5 and clamp ring 3 reliably affixed, the inner side surface of clamp ring 3 has annular gear mouth 32, and accordingly, the outboard end of conus portion 203 is extended with the collar 204 keeping off mouth 32 plug-in mounting with this annular and coordinate.Collar 204 can keep off stable in mouth 32 plugging together in annular, and being aided with welding can strengthen join strength.
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, under the inclined-plane leading role of conus portion 203, the ailhead of screw to the extruding force of movable sheath 5, by the radial component of the axle core component that is converted into seal ring 4 and movable sheath 5 pairs of pipe fittings 100.
For preventing the ailhead of screw from boring broken movable sheath 5, the ailhead of screw is set to bulb 11.
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.
