Specific embodiment
Illustrate specific embodiment of the present utility model with reference to the accompanying drawings and examples, but following embodiment only uses
It is described in detail the utility model, does not limit the scope of the utility model in any way.
Embodiment 1:
It please refers to Fig.1 to Fig.4.
As shown in Figure 1, compression type pipe connection device provided by the embodiment of the utility model includes split ring 11, gland 12 and pipe
Part 13, in the present embodiment, pipe fitting 13 is a threeway, when pipeline 14 is connected with pipe fitting 13, first by gland 12,11 and of split ring
Sealing ring 15 is sequentially sleeved at 14 lower end of pipeline, then 14 lower end of pipeline is inserted into the corresponding interface of pipe fitting 13, then by gland
12 are screwed on the interface of pipe fitting 13, and sealing ring 15 is pressed between split ring 11 and pipe fitting 13, and split ring 11 is pressed in
Between gland 12 and pipe fitting 13, after gland 12 is connected with pipe fitting 13,11 undergauge of split ring holds pipeline 14 tightly, realizes pipeline 14
With the connection between pipe fitting 13, and sealing ring 15 plays sealing function, prevents leak.
Specifically, conical surface bellmouth 131 is exactly corresponding in pipe fitting 13 as shown in Fig. 2, pipe fitting 13 is equipped with conical surface bellmouth 131
The conical surface is arranged in interface, and gland 12 includes integrally formed top surface 121 and ring-shaped periphery 122, and 122 lower part of ring-shaped periphery is equipped with interior spiral shell
The outside wall surface of line, conical surface bellmouth 131 is equipped with corresponding external screw thread, for being connected between gland 12 and pipe fitting 13.
The top surface 121 of gland 12 is equipped with the through-hole 123 for passing through for pipeline 14, and the internal diameter of ring-shaped periphery 122, which is greater than, to be opened

122 top of face does not have the inner wall height of tapping, and the bottom end outer diameter of split ring 11 is less than 131 top internal diameter of conical surface bellmouth, this
After sample, gland 12 and pipe fitting 13 are connected through a screw thread, the top of split ring 11 contradicts the bottom of split ring 11 below top surface 121
End is located on the conical surface of conical surface bellmouth 131, and therefore, split ring 11 is pressed between gland 12 and pipe fitting 13.
As shown in figure 3, the outer peripheral surface of split ring 11 is the from top to bottom gradually conical surface of undergauge, split ring 11 is along being axially arranged with
Through the opening 111 of its wall surface, the internal diameter of split ring 11 is suitable with 14 outer diameter of pipeline, and therefore, 11 lower end of split ring is held with the conical surface
Mouth 131 squeezes, and 11 undergauge of split ring can be made to hold pipeline 14 tightly.
The undergauge due to the radial force that is applied by conical surface bellmouth 131 of split ring 11, split ring 11 can hold the conical surface
Mouth 131 applies reversed radial forces, and 131 outside wall surface of conical surface bellmouth is screwed with gland 12, therefore, the wall surface and pressure of conical surface bellmouth 131
Lid 12 bears the radial force that split ring 11 applies jointly, to mitigate 12 stress size of gland, gland 12 is relatively thin to be met
Requirement reduces cost of manufacture, and reduces the volume of gland 12, and gland 12 is made to be suitable for using in small space, in addition, this
Kind connection type is stronger due to withstanding forces, and suitable for the connection of big-diameter pipeline, in actual use, is hinged with using the compression type pipe
The pipeline for setting connection internal diameter 50-200mm still fastens very much, and leakproofness is good.
15 lower, outer perimeter face 151 of sealing ring is tapered surface corresponding with conical surface bellmouth 131, and 11 lower end of split ring is equipped with inner cone
Face 112,15 upper periphery face 152 of sealing ring is tapered surface corresponding with inner conical surface 112, after gland 12 is connected with pipe fitting 13,
Sealing ring 15 is pressed between inner conical surface 112 and conical surface bellmouth 131.The area and bore of conical surface bellmouth 131 are greater than split ring
11 lower end outer diameters, also greater than 15 outer diameter of sealing ring, so that conical surface bellmouth 131 can accommodate simultaneously under sealing ring 15 and split ring 11
End.
As shown in Fig. 2, in the present embodiment, it is uniformly distributed in the outer peripheral surface of gland 12 in order to enhance the bearing capacity of gland 12
There are multiple bar shaped reinforcing ribs 124.
Embodiment 2
Please refer to Fig. 4 and Fig. 5.
As shown in figure 4, the present embodiment the difference from embodiment 1 is that, be additionally provided with bipassage ring in the inner wall of sealing ring 15
Shape protrusion 153, annular protrusion 153 are arranged obliquely, form hangnail, have the function of compressing pipeline 14, enhancing sealing
The leakproofness of circle 15.In addition, as shown in figure 5, the inner wall in split ring 11 is additionally provided with the compression protrusion 113 of twice in a ring,
It compresses protrusion 113 to be arranged obliquely, forms hangnail, have the function of compressing pipeline 14.
Further, as shown in fig. 6, in the present embodiment, gland 12 is equipped in addition to the main part outer peripheral surface in lower part
Outside bar shaped reinforcing rib 124, also in end circumferentially arranged with the reinforcing rib 125 of multiple convex, to enhance the intensity of gland 12.
The utility model is described in detail above in conjunction with drawings and examples, still, the skill of technical field
Art personnel, can also be to each specific in above-described embodiment it is understood that without departing from the purpose of the present invention
Parameter changes, and forms multiple specific embodiments, is the common variation range of the utility model, no longer detailed one by one herein
