Abstract

A kind of slide-in type Drop-proof is taken over, relate to connecting tube technical field, comprise externally connected pipe, inner connecting tube and seal ring, one end of described inner connecting tube is inserted into the inside of externally connected pipe one end, described seal ring is arranged between inner connecting tube and externally connected pipe, it is characterized in that: described externally connected pipe is provided with seal groove in the inner side of the one end being connected with inner connecting tube, described seal ring is arranged on the inside of seal groove.The utility model is simple and reasonable, easy to use, and seal ring is not easy landing, and good sealing effect.

Description

A kind of slide-in type Drop-proof is taken over
Technical field:
The utility model relates to connecting tube technical field, and specifically a kind of slide-in type Drop-proof is taken over.
Background technique:
Connecting tube be in daily life one of common device arriving, particularly ductile iron pipe pipe fitting supporting with it once appearance, just caused gazing at of the world, develop very rapid.It has been widely used in the fields such as industrial or agricultural water delivery, oil transportation and gas transmission of city and country at present.The material of nodular cast iron pipe fittings: ferrite ductile cast iron.The specification of nodular cast iron pipe fittings has: DN80~DN2000mm ' at present pipe fitting has developed three kinds of interface shapes: T-type (slide-in type), K-type (mechanical type) and N1-type (mechanical type).There is the problem of O-ring seal landing in installation process in T-type at present.And the effect only sealing with seal ring is poor.
Model utility content:
Technical problem to be solved in the utility model is to provide a kind of seal ring to be not easy landing, and the slide-in type Drop-proof of good sealing effect is taken over.
The technical problem solving adopts following technological scheme:
A kind of slide-in type Drop-proof is taken over, comprise externally connected pipe, inner connecting tube and seal ring, one end of described inner connecting tube is inserted into the inside of externally connected pipe one end, described seal ring is arranged between inner connecting tube and externally connected pipe, it is characterized in that: described externally connected pipe is provided with seal groove in the inner side of the one end being connected with inner connecting tube, described seal ring is arranged on the inside of seal groove.
On the internal surface of described seal groove, be provided with flange collar, described seal ring is provided with the groove that flange collar coordinates on the outer surface contacting with externally connected pipe.Seal ring is firmly more stable, and has increased the area of contact between seal ring and externally connected pipe, thereby increases sealing effect.
Described flange collar and the quantity of groove are all two.Seal ring is firmly more stable, and has increased the area of contact between seal ring and externally connected pipe, thereby increases sealing effect.
The external frame of described flange collar and the cross section of groove is all circular-arc.Be convenient to coordinating between seal ring and externally connected pipe, flange collar is more easily assembled to the inside of groove.
Described externally connected pipe is provided with the chamfering of 10~15 degree in the ingress, one end being connected with inner connecting tube.Be convenient to the access of seal ring and inner connecting tube.
The utility model prevents the problem of seal ring landing in installation process.In sealing, seal groove and seal ring play the effect of double-sealing mould, and sealing effect is even more ideal.
The beneficial effects of the utility model are: the utility model is simple and reasonable, easy to use, and seal ring is not easy landing, and good sealing effect.
Accompanying drawing explanation:
Fig. 1 is the utility model structural representation.
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of slide-in type Drop-proof is taken over, comprise externally connected pipe 1, inner connecting tube 2 and seal ring 3, one end of inner connecting tube 2 is inserted into the inside of externally connected pipe 1 one end, seal ring 3 is arranged between inner connecting tube 2 and externally connected pipe 1, externally connected pipe 1 is provided with seal groove 4 in the inner side of the one end being connected with inner connecting tube 2, and seal ring 3 is arranged on the inside of seal groove 4.On the internal surface of seal groove 4, be provided with flange collar 5, seal ring 3 is provided with the groove 6 that flange collar 5 coordinates on the outer surface contacting with externally connected pipe 1.The quantity of flange collar 5 and groove 6 is all two.The external frame of the cross section of flange collar 5 and groove 6 is all circular-arc.Externally connected pipe 1 is provided with the chamfering 7 of 12 degree in the ingress, one end being connected with inner connecting tube 2.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
