Abstract
The utility model discloses an annular pressure enhancement type high-pressure water mist pipe fitting and the connection thereof. The annular pressure enhancement type high-pressure water mist pipe fitting includes a connecting pipe fitting body and a connecting pipeline (8), three grooves (6) are arranged on the outer pipe wall of the connecting part (5) of the connecting pipe fitting body, a seal ring (7) is arranged in one groove (6) in the middle, the connecting pipeline (8) is sleeved with a sleeve (9), and three bulges (10) are arranged on the inner wall of the sleeve (9). The high-pressure water mist pipe fitting has the connecting advantages that the grooves (6) are pre-manufactured on the connecting pipe fitting body, thereby enabling the deformation of the pipeline (8) to be fuller after being subjected to annular pressure; and the sleeve (9) additionally equipped with the three inner bulges enhances the strength at the joint of the connecting pipe (8), so that the pipe fitting can bear very high transmission medium pressure and can conveniently enter a construction site for use.
Description
Technical field
The utility model relates to a kind of connection set of connecting tube, particularly relates to a kind of ring and presses reinforced heavy pressure fine spray pipe fitting and connection thereof.
Background technique
At present, a large amount of stainless steel pipeline that use in the feedwater fire protection pipeline, because the common tube wall of this class stainless steel pipeline is thinner, the suitable ring that adopts is pressed connection, ZL03234617.4 is disclosed to be exactly the method that connects this class steel pipe, when the pressure medium of carrying in the pipeline is very high, just needs very thick pipe fitting and steel pipe, the pipe fitting and the steel pipe difficulty very that connect such wall thickness, directly the mode of ring pressure can not adapt to being connected of heavier walled fitting and thick walled steel tube.
The model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of connection precision height, the sealing reinforced heavy pressure fine spray connection pipe fitting of ring pressure more reliably is provided.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
A kind of ring is pressed reinforced heavy pressure fine spray pipe fitting and connection thereof, comprise connection pipe fitting body and connecting tube, the outer tube wall of the connection part of described connection pipe fitting body is provided with three road grooves, and described connecting tube is with sleeve outward, and the inner tubal wall of sleeve is provided with three road projectioies.
In order to realize the utility model better:
Further technological scheme is: be provided with seal ring in one groove in described centre.
Further technological scheme is: described connection pipe fitting body is any in straight-through pipe fitting, bend pipe tools, tee pipe fitting, four-way pipe fitting, the straight-through pipe fitting of reducing, reducing bend pipe fitting, reducing tee pipe fitting, the reducing cross pipe fitting.
Compared with prior art, the beneficial effects of the utility model are:
In the technical solution of the utility model: ring of the present utility model presses the connection advantage of reinforced heavy pressure fine spray pipe fitting to be on the connection pipe fitting body three road grooves in advance prefabricated, can make the connecting tube distortion after ring is pressed more abundant, the sleeve that has three road internal projection that installs additional has increased the intensity of connecting tube joint again, this device can bear the pressure of very high fed sheet of a media, and can easily enter the job site use.

Embodiment
Below in conjunction with embodiment the utility model is described in further detail, but mode of execution of the present utility model is not limited thereto.
As Fig. 4, Fig. 5 and shown in Figure 6, a kind of ring is pressed reinforced heavy pressure fine spray pipe fitting and connection thereof, comprises tee pipe fitting 4 and connecting tube 8, and the connection part 5 of tee pipe fitting 4 has three places; The outer tube wall of connection part 5 is provided with three road grooves 6, is provided with seal ring 7 in one groove in above-mentioned centre 6; Be with sleeve 9 outside the above-mentioned connecting tube 8, the inner tubal wall of sleeve 9 is provided with three road projectioies 10.
The Placement that the utility model is strengthened the heavy pressure fine spray pipe fitting is: according to pre-designed connecting tube drawing, select suitable tee pipe fitting 4 and connecting tube 8, connection part 5 is inserted in the hole of connecting tube 8, and the sleeve 9 of three road projectioies 10 arranged in putting outside connecting tube 8,9 pressurizations make connecting tube 8 with sleeve 9 distortion to a kind of ring-pressing tool that can use ZL200520036619.4 to announce to sleeve, outer twice projection 10 is clamp-oned connecting tube 8 in the groove 6 of pipe fitting connection part 5 in the sleeve 9, middle projection 10 crush seal circles 7, make sealing more reliable, and increased the intensity of steel pipe joint.
When the connection pipe fitting body was other structure, Placement was consistent with such scheme, was described so enumerate embodiment no longer separately.Its connection pipe fitting main body structure is as follows:
The connection pipe fitting body is during for straight-through pipe fitting 1, the structure of straight-through pipe fitting 1 as shown in Figure 1, its connection part 5 is two places, the outer tube wall at every place is provided with three road grooves 6.
When the connection pipe fitting body is bend pipe tools 2, the structure of bend pipe tools 2 as shown in Figure 2, its connection part 5 is two places, the outer tube wall at every place is provided with three road grooves 6.
When the connection pipe fitting body is four-way pipe fitting 3, the structure of four-way pipe fitting 3 as shown in Figure 3, its connection part 5 is for everywhere, the outer tube wall at every place is provided with three road grooves 6.
When the connection pipe fitting body of the technical program is the similar pipe fitting of the straight-through pipe fitting of reducing, reducing bend pipe fitting, reducing tee pipe fitting, reducing cross pipe fitting or other, still in the protection domain of present specification.
