Abstract
The utility model discloses a double-sealing clamping-pressing type pipe fitting, belonging to the pipe connectors. The clamping-pressing type pipe fitting in the prior art has a poor sealing effect, a small drawing force, and a narrow application range. In the double-sealing clamping-pressing type pipe fitting, inner ring grooves are positioned on the inner walls of outer rings; inner ring walls are disposed on the inner sides of the outer ring walls while outer sealing rings are positioned in the inner ring grooves; outer ring grooves are disposed on the outer walls of the inner ring walls; inner sealing rings are positioned in the outer ring grooves; plugging ports are formed between the outer ring walls and the inner ring walls; pipes are inserted into the plugging ports; the outer ring sealing rings are in contact with the outer walls of the pipes under the pressure and the inner sealing rings are in contact with the inner walls of the pipes under the pressure so as to realize inside-outside double-sided sealing. The double-sealing clamping-pressing type pipe fitting is characterized by a good sealing effect, a big drawing force and a wide range of usage. The double-sealing clamping-pressing type pipe fitting is applicable to connecting copper pipes, stainless steel pipes and composite pipes.
Description
Technical field
The utility model belongs to pipe joint, specifically a kind of double-sealing clamp-press type pipe.
Background technique
Existing clamp-press type pipe as shown in Figure 1, is to establish the Inner annular groove at the inwall of external annulus, in the Inner annular groove, exterior seal ring is arranged, and as shown in Figure 2, pipe is inserted to external annulus, and exterior seal ring is squeezed to contact and realizes sealing on the outer wall of pipe.The pipe fitting sealing effect of this structure is poor, and pulling capacity is little, and using scope is little, can only be applicable to connecting copper pipe, Stainless Steel Tube, is unsuitable for connecting composite pipe.
The model utility content
The technical assignment of the technical problems to be solved in the utility model and proposition is that to overcome existing clamp-press type pipe sealing effect poor, and pulling capacity is little, and the defect that using scope is little provides a kind of double-sealing clamp-press type pipe.
For achieving the above object, double-sealing clamp-press type pipe of the present utility model, it has an external annulus that can block pressure, the inwall of described external annulus has the Inner annular groove, in described Inner annular groove, exterior seal ring is arranged, it is characterized in that: the inboard of described external annulus is provided with internal ring wall, and the outer wall of described internal ring wall is provided with outer groove, in described outer groove, inner seal ring is arranged, between described external annulus and internal ring wall, form interface.
As the optimization technique means: described Inner annular groove, outer groove shift to install.Described external annulus is welded on described internal ring wall.Described Inner annular groove forms for implement from inside to outside radially roll extrusion at the inwall of described external annulus.Described outer groove forms for implement radially roll extrusion at the outer wall ecto-entad of described internal ring wall.
The beneficial effects of the utility model are: when in the external annulus inwall has Inner annular groove, Inner annular groove, exterior seal ring being arranged, internal ring wall is established in inboard at external annulus, the outer wall of internal ring wall is established outer groove, and inner seal ring is arranged in outer groove, between external annulus and internal ring wall, forms interface; Pipe is inserted in interface, exterior seal ring be squeezed contact on tube outer wall, the inner seal ring contact that is squeezed realizes inside and outside dual face seals, good sealing effect on tube wall, pulling capacity is large, using scope is wide, can be applicable to connecting copper pipe, Stainless Steel Tube, also is suitable for connecting composite pipe.

Embodiment
Below in conjunction with Figure of description, the utility model is described further.
Double-sealing clamp-press type pipe of the present utility model, as shown in Figure 3, it has an external annulus 1 that can block pressure, the inwall of external annulus 1 has Inner annular groove 2, exterior seal ring 3 is arranged in Inner annular groove 2, and the inboard of external annulus 1 is provided with internal ring wall 4, and the outer wall of internal ring wall 4 is provided with outer groove 5, inner seal ring 6 is arranged in outer groove 5, form interface 7 between external annulus 1 and internal ring wall 4.
As shown in Figure 4, pipe 8 is inserted in interface 7, use the card press tool to make its distortion from the external annulus 1 of pipe fitting wild card pressure pipe part, make exterior seal ring 3 be squeezed reliably contact on pipe 8 outer walls, inner seal ring 6 contact reliably that is squeezed realizes inside and outside dual face seals on pipe 8 inwalls, good sealing effect, pulling capacity is large, using scope is wide, can be applicable to connecting copper pipe, Stainless Steel Tube, also be suitable for connecting composite pipe (as plastic stainless-steel composite-tubes, steel-plastic composite pressure pipe, aluminium-plastic composite pipe etc.).
Concrete, Inner annular groove 2, outer groove 5 shift to install, and make compact structure.External annulus 1 is welded on internal ring wall, is convenient to manufacture.Inner annular groove 2 forms for implement from inside to outside radially roll extrusion at the inwall of external annulus 1.Outer groove 5 forms for implement radially roll extrusion at the outer wall ecto-entad of internal ring wall 4.
