Abstract

The utility model discloses a sealing ring structure for serving as a contrast plastic steel trench groove is connected, including lining plastic steel pipe, sealing washer and clamp, lining plastic steel pipe comprises outer steel pipe and the plastic tubing that sets up at outer steel pipe inner wall, and the outside at lining plastic steel pipe both ends is equipped with the draw -in groove respectively, and the clamp is installed in the draw -in groove and the fastening, and the sealing washer is established on the outer circumference of two lining plastic steel union couplings ends, and the sealing washer extends to the port that is used for sealed lining plastic steel to manage on the port faces of two lining plastic steels pipes, adoption the utility model discloses carry out the slot when connecting at the engineering scene, make the steel pipe section with the fluid medium contact, more excellent anti -corrosion performance has.

Description

A kind of ring structure connected for line plastic-steel tube groove
Technical field
The utility model relates to the line plastic-steel tube that groove connects, and particularly relates to a kind of ring structure connected for line plastic-steel tube groove.
Background technique
In prior art, when line plastic-steel tube carries out groove connection in engineering site is installed, be adopt a kind of interior corrosion-resistant nodular cast iron pipe fittings, carry out preservative treatment at pipe fitting intrinsic silicon, thisly anticorrosionly can be that lining is moulded, powder coating, rotational moulding, the anticorrosion form such as enamel, and then to connect; But no matter adopt the interior anticorrosion form of which kind of form, all cannot avoid the contact of the flowing medium of line plastic-steel tube port irony and conveying, make line plastic-steel tube when adopting groove Placement, the all inevasible secondary pollution that there is flowing medium, defines hidden danger also to the antiseptic power of pipe-line system and safe operation simultaneously.
Model utility content
In order to overcome the defect of above-mentioned prior art, the utility model provides a kind of ring structure connected for line plastic-steel tube groove, its objective is when the engineering site applying line plastic-steel tube carries out groove connection, can not allow flowing medium and pipe fitting substrate contact, make it have good antiseptic power and pipe-line system sealability can not be caused to decline, ensureing security of system.Thus guarantee the quality that the Corrosion Protection of line plastic-steel tube and pipeline connect, and easy construction, quick.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of ring structure connected for line plastic-steel tube groove, comprise line plastic-steel tube, seal ring and clip, described line plastic-steel tube is made up of outer steel pipe and the plastic tube being arranged on outer steel pipe inner wall, it is characterized in that: the outside at described line plastic-steel tube two ends is respectively equipped with draw-in groove, it is interior and fastening that described clip is arranged on draw-in groove, described seal ring is located on the excircle of two line plastic-steel tube connecting ends, for sealing the port of line plastic-steel tube on the port surface that seal ring extends to two line plastic-steel tubes.
Described seal ring is T-shaped seal ring or y-type seal ring, and T-shaped seal ring or y-type seal ring both can seal the excircle of line plastic-steel tube (radial direction) connection, and the port of line plastic-steel tube (axis) can be made again to seal.
Described clip is arranged in draw-in groove, is inserted in bolt and uses fastening nuts.
The utility model has the following advantages:
1, the outside at the utility model line plastic-steel tube two ends is respectively equipped with draw-in groove, it is interior and fastening that described clip is arranged on draw-in groove, described seal ring is located on the excircle of two line plastic-steel tube connecting ends, for sealing the port of line plastic-steel tube on the port surface that seal ring extends to two line plastic-steel tubes, adopt the utility model when engineering site carries out groove connection, steel pipe section is not contacted with flowing medium, there is more excellent Corrosion Protection.
2, the utility model does not change pipe fitting original structure, convenience quick for installation, is applicable to the pipe-line system that various employing groove connects.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the C-C direction view of Fig. 1;
Fig. 3 is that the seal ring of this practicality and the port of line plastic-steel tube are connected figure.
Mark in figure: 1, line plastic-steel tube, 2, outer steel pipe, 3, plastic tube, 4, seal ring, 5, draw-in groove, 6, clip, 7 bolts, 8, nut.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
Embodiment 1
As figure, shown in Fig. 2 and Fig. 3, a kind of ring structure connected for line plastic-steel tube groove, be mainly used in sealing when line plastic-steel tube connects, comprise line plastic-steel tube 1 (being generally used for two of connection), seal ring 4 and clip 6, described line plastic-steel tube 1 is made up of with the plastic tube 3 being arranged on outer steel pipe 1 inwall outer steel pipe 2, the outside at described line plastic-steel tube 1 two ends is respectively equipped with draw-in groove 5, it is interior and fastening that described clip 6 is arranged on draw-in groove 5, described seal ring 4 is located on the excircle of two line plastic-steel tube 1 connecting ends, for sealing the outside of line plastic-steel tube 1, seal ring 4 is provided with extension part simultaneously, for sealing the port of line plastic-steel tube on the port surface that this extension part extends to two line plastic-steel tubes 1, make two line plastic-steel tubes 1 when connecting, radial direction is all sealed with axial, can not allow flowing medium and pipe fitting substrate contact, make it have good antiseptic power and pipe-line system sealability can not be caused to decline, ensure security of system.
In order to improve the sealing effect of the ring structure that line plastic-steel tube groove connects, described seal ring 4 is T-shaped seal ring or y-type seal ring, T-shaped seal ring or y-type seal ring both can seal the excircle of line plastic-steel tube (radial direction) connection, and the port of line plastic-steel tube (axis) can be made again to seal.
Further, described clip 6 is arranged in draw-in groove 5, is inserted in bolt 7 and uses nut 8 fastening.
