Abstract
The utility model provides a pipeline connecting mechanism, which is composed of a flute arranged on a pipe body, a cam arranged in the flute, a clamping cap which is in sleeve joint on the pipe and is provided with a spacing boss, a pipe joint which is butted with the pipe and is provided with a boss end surface corresponding to the diameter of the pipe, an end surface sealing ring arranged between the boss end surface and the end surface of the pipe and a connecting structure arranged between the clamping cap and the pipe joint. The utility model can effectively prevent the separation of the connecting pipe. The installation, and the assembly and disassembly are very convenient. The utility model is especially suitable for the connecting use of the non-galvanizing pipe.
Description
The utility model relates to the pipeline connecting device in the pipeline transporting system.
The pipeline transporting system is by several pipes composition that is connected.Quality of connection between the tube and tube is bad, and the lighter causes sealing bad and cause seepage, weight person also can make coming off between the joint causing whole pipe-line system to be paralysed easily.The modal mode of the connection of larger-diameter pipe is the flange plate Placement, because the pressure of large diameter tube transmission medium is big, retiring relatively of pipe way taken place easily and causes the not tight phenomenon of connecting end face seal.Connection between lower diameter tube more commonly with a straight coupling directly with the two ends of the pipe that is threaded, between internal and external screw thread, realize sealing with the filler of linen thread or white glues band and so on.This to come the shortcoming one of ways of connecting with screw thread and filler simply be that its filler are difficult to be blocked in evenly, rightly between the inside and outside connecting thread and play seal action, and filler are not durable, and often leaks in use for some time.
The purpose of this utility model is the above-mentioned shortcoming that overcomes prior art, provides a kind of sealing by force, axially to connect reliable anti-holding back pipeline bindiny mechanism.
Realize the anti-holding back pipeline bindiny mechanism of the utility model purpose, by be opened in groove on the pipe body, be installed in projection in this groove, be socketed in the fastening cap that has a positive stop lug boss on the pipe, dock with pipe have one and the pipe joint of the corresponding raised head face of diameter of pipe, be arranged on the end-face seal ring between this raised head face and the pipe end face and be arranged on fastening cap and pipe joint between linkage structure constituted.Groove can be made when producing, also can pre-when mounted groove.The section configuration of its groove can be rectangle, arc, different shape such as trapezoidal, can be the circular groove that is communicated with, and also can be the interval trough of even cloth.Earlier fastening cap is packed into pipe during installation, again projection is put in the groove, again end-face seal ring is placed in the raised head face of pipe joint and docks with the tube end face then, be connected pipe and pipe joint by fastening cap with linkage structure between the pipe joint again.Because the positive stop lug boss of fastening cap abuts against on the projection when the connecting tube joint, projection is mounted in the groove of pipe immotile, thus fastening cap for pipe be can not produce axially movable.That is to say in connection procedure and will pull to pipe by pipe joint, up to make end-face seal ring reliably clamping connection till between pipe and the pipe joint and finish and be connected.Realize that by end-face seal ring sealing, fastening cap realize that with linkage structure between the pipe joint anti-holding back is connected.
Described fastening cap can be made of the internal thread and the corresponding outer line line that is arranged on the pipe joint that are located on the fastening cap with linkage structure between the pipe joint.This mode of structure only must rotate fastening cap both can finish connection easily.Obviously, internal and external screw thread also can be instead for establishing it.
Described fastening cap can also be made of corresponding connecting through hole and the connecting bolt of cross-under in connecting through hole that is opened on fastening cap and the pipe joint with linkage structure between the pipe joint.This structure comparison flange plate structure form.
For further improving sealability, also can on the projection of pipe and the perisporium between the pipe joint, a radial direction seal ring be set.By the tube end apical grafting on the end-face seal ring, the end face of projection realizes double seal with the radial direction seal ring apical grafting on pipe joint.Another benefit of this mode is the delivered inside pressure of pipeline can be passed to linkage structure between fastening cap and the pipe joint by radial direction seal ring.This is very favorable to connecting flexible tube by pipe joint.
For ease of making and installing, described groove can be made annular groove, and projection can be elastic collar.
The utility model has the advantages that to prevent effectively that connecting moving back of pipe takes off, good airproof performance, simple in structure is installed, changes all very convenient.Be particularly suitable for using as the connection of fire hose reel, this class black pipe of snakelike flexible pipe.

Embodiment 1:
Referring to Fig. 1, fastening cap 2 is a nut type fastening cap, is provided with a positive stop lug boss 8.The shape of this positive stop lug boss 8 except that can inclined-plane boss as shown in fig. 1, can also be as shown in Figure 2 the shape that has a circular arc scrobicular ring 9 or the shape of the shape of cambered surface as shown in Figure 4 10 or ladder as shown in Figure 4 11 etc.Groove 4 is an annular groove in the present embodiment, and projection 3 is an elastic collar.Its section configuration can be rectangle as shown in Figure 5, circular arc shown in Figure 6, shown in Figure 7 trapezoidal or the like.Pipe joint 7 is connected with fastening cap by screw thread to be realized docking with pipe 1, both constitutes linkage structure between fastening cap and the pipe joint by internal thread on the fastening cap and the outside thread on the pipe joint.Pipe joint have one with the corresponding raised head face 5 of diameter of pipe, end face seal Fig. 6 is arranged between pipe end face and the raised head face.
Embodiment 2:
As shown in Figure 8, present embodiment and embodiment's 1 structure is basic identical.Different is to set up a radial direction seal ring 15, and Fig. 9 has provided the installation form of another kind of radial direction seal ring.16 is packing ring among the figure.This packing ring also can be made as one with projection 3.Positive stop lug boss 8 is made as trapezoidal, and its inner rim face matches with the external cylindrical surface of projection 3 and comes off from groove with restriction projection 3.
Embodiment 3:
As shown in figure 10, present embodiment is different with preceding embodiment is that linkage structure between its fastening cap and the pipe joint is the flange plate type linkage structure.Both connecting through hole 19,20 and the connecting bolt 21 of cross-under in through hole that is opened on fastening cap 17 and the pipe joint 18 by correspondence constituted.
