Description

Pipeline is without fiery link

Technical field

The utility model relates to a kind of pipe joint, particularly relates to a kind of pipeline without fiery link, belongs to pipeline connection area.

Background technique

At present, pipe connecting method mostly is welding, not only requires that operator have technology and experience in process, and needs to eliminate disaster hidden-trouble emphatically, brings a lot of troubles to workman's operation.

In order to solve the problem, a kind of line seal jointing of those skilled in the art's model utility, it does not need operator to carry out special fire prevention operation.As publication number is: the patent of CN1603671, it discloses one " pipe joint "; Specifically as shown in Figure 1, be inserted into by pipeline in pipe joint, form the movement to adapter body by rotating nut, in moving process, produce axial tension in stop ring incision pipe, it seals and completes by 0 type circle sealing component.

This pipe connector lug, when stop ring is cut in pipe, pipe can internally produce deformation because of stressed, the position that this deformation can cause stop ring to be cut in pipe is very little, the risk that pipe is pulled out can be produced in the expansion naturally or vibrations process of metal, in addition, sealing component relies on dimensional fits to complete the sealing with pipe, still has because expansion or the vibrations process naturally at metal can produce the risk of leakage in permanent connection procedure.

For another example publication number is: the patent of CN103162027, it discloses " a kind of line seal jointing "; Specifically as shown in Figure 2, pipeline, after expand tube, utilizes connecting ring through axial force, is connected on interior connecting bushing.The fixing mutual pressure according to connecting ring and liner connecting sleeve of pipeline is achieved, and the space in addition between pipeline and connecting bushing is sealed by sealing surface, and in this structure, if pipeline is drawn or wrenched, the mutual pressure of connecting ring and connecting bushing is weakened.Therefore, for using for a long time, utilize the mutual pressure of connecting ring and connecting bushing and sealing surface to realize conservation condition and air-proof condition by being difficult to maintain.

Embodiment

Below in conjunction with embodiment, the utility model is described in further detail.

As shown in Figures 3 to 6, a kind of pipeline, without fiery link, comprises main body 1, described main body 1 is step structure, and its end difference is provided with outside thread 3, described end difference is socketed with a rotating nut 4, in rotating nut 4, is provided with internal thread intermeshing with outside thread 3; Described main body 1 and rotating nut 4 are respectively arranged with the aperture of inserting for pipeline 15; Be provided with black box 18 in the end difference of described main body 1, in described rotating nut 4, be provided with cone 11, and cone 11 and black box 18 cooperatively interact and act on.This pipe joint solves the problem connected without fire.

Be provided with hollow portion in the end difference of described main body 1, described black box 18 is arranged in this hollow portion, and black box 18 is made up of sealing gasket 5, pad 6, O RunddichtringO 1 and chock 8 successively; The slip of chock 8, can promote O RunddichtringO 1, pad 6 and sealing gasket 5 and travel forward, and in the process of motion, O RunddichtringO 1 and sealing gasket 5 produce the sealing to pipeline 15 because of active force.

Described chock 8 is L-type structure, and the protuberance of chock 8 contacts with the bottom 9 of main body 1 under force, and stop, described sealing gasket 5 is V-type pad.

Described cone 11 comprises conehead 111, skeleton 112 and puts up a bridge 12; Described skeleton 112 is hollow taper, one end of this taper is small sircle hole, the other end is big hole, insert several coneheads 111 uniformly on the hole wall being positioned at small sircle hole, the top of described conehead 111 is provided with several and puts up a bridge 12, and the distance between described bridging 12 and skeleton 112 forms combination section 113.

In this configuration, in order to make conehead 111 not be subject to ectocine in the process of forward motion, specially devising skeleton 112, it solving rotating nut 4 conehead 111 in the process to main body 1 movement and directly contact chock 8 and produce the distortion power of mistake; The design of combination section 113 can not produce extra impact in order to make between all parts in cone 11.

Described conehead 111 under force its point 114 is cut in the outer tube wall of pipeline 15, and described point 114 is fillet structure, point 114 is designed to fillet structure, can prevents point 114 from damaging pipeline 15 outer wall because of too sharp.

Also be provided with O RunddichtringO 2 13 in described rotating nut 4, described O RunddichtringO 2 13 is tightly placed on the outer wall of pipeline, and for outdoor environment, O RunddichtringO 2 13 can the entering of air-isolation and moisture, and better plays the effect of sealing.

The end difference of described main body 1 is also provided with safety buckle 2; this safety buckle 2 clamps with the block hook structure 19 of rotating nut 4 end; the setting of safety buckle 2; prevent artificial rotating nut 4 and main body 1 being departed from; ensure that each parts of main body 1 and rotating nut 4 inside can be placed as requested and can not be upset, serve good safety protection effect.

The position that described pipeline 15 inwall contacts with main body 1 is provided with neck bush 10, cooperatively interacting of O RunddichtringO 1, sealing gasket 5, cone 11 and neck bush 10, the sealing of pipeline 15 and pull resistance are promoted, eliminates and too meticulous impact is required on line size.

The end difference of described main body 1 is provided with marking line 14, when rotating nut 4 is screwed to the position of marking line, then illustrates that rotating nut 4 has been screwed on the outside thread 3 of main body 1, and connects fastening, avoid rotating nut and turn situation not in place.

Its working procedure is as follows: pipeline 15 is successively through O RunddichtringO 2 13, cone 11, chock 8, O RunddichtringO 1, pad 6, the sealing gasket 5 also final bottom 16 arriving main body; Turn rotating nut 4, the root progressively to the outside thread 3 of main body 1 is advanced.

Rotating nut 4 is in the process of rotating, cone 11 can be forced to move to chock 8, in the process, cone 11 is under the effect of the guide surface 17 of rotating nut 4, and cone 11 can move radially, and now point 114 position of conehead 111 can be cut in the outer wall of pipeline 15, produce enough large snap-in force, even if do in order to very large pulling capacity in the axial direction, pipeline 15 also can not be pulled out, but is fixed therein firmly.

Rotating nut 4 continues to rotate forward, forces chock 8 forced-slip, contact the bottom 9 of main body until chock 8 till; The slip of chock 8, has promoted O RunddichtringO 1, pad 6 and sealing gasket 5 and has travelled forward, and in the process of motion, O RunddichtringO 1 and sealing gasket 5 produce the sealing to pipeline 15 because of active force.
