Abstract

The utility model relates to a circlip type steel pipe connector, comprising a steel pipe connector seat, a nut and a sealing ring, and both ends of the steel pipe connector seat have chamfer angles theta. The utility model is characterized in that the inner of the nut has an inner cavity, and the inner of the inner cavity has a circlip. When the utility model is used, a steel pipe to be connected does not need to be carry out welding or hinging thread. As is proved by a 3 MPa hydraulic test, sealing is good, and the utility model has the advantages that mounting efficiency is enhanced, and labor strength is reduced.

Description

Circlip type steel pipe joiner

The utility model relates to a kind of circlip type steel pipe joiner.

Existing steel pipe attached method is generally welding and scyewed joint, and it needs corresponding welding equipment and heavy strand screw thread equipment when mounted, install time-consuming, efficient is low.

When the purpose of this utility model provides a kind of installation, need not treat and connect steel pipe hinge screw thread or freeze circlip type steel pipe joiner simple in structure, easy for installation.

In order to achieve the above object, the utility model is achieved in that it comprises that steel pipe connects headstock, nut and seal ring, has a chamfering θ at the two ends of pipe joint seat; Its feature in: in nut, be provided with an inner chamber, in inner chamber, be provided with a jump ring.The section of inner chamber has a chamfering near hand of spiral.The inner ring indention of jump ring, the shape of itself and inner chamber matches.

The utility model compared with prior art has following advantage.

Do not need steel pipe hinge screw thread to be installed when 1, using or freeze, saved mounting cost greatly, improved working efficiency.

2, easy manufacturing simple in structure;

3, easy for installation.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of jump ring.

Below in conjunction with accompanying drawing and example the utility model is done further detailed description:

As shown in Figure 1, 2, comprise steel pipe joiner seat (6), nut (3) and seal ring (4), a chamfering θ is arranged at the two ends of steel pipe joiner seat (6), in the utility model, the θ angle is 30 °, has an inner chamber (3a) in nut (3), is provided with a jump ring (2) in inner chamber (3a).The section of inner chamber (3a) has a chamfering by hand of spiral, the inner ring indention of jump ring (2), and the shape of itself and inner chamber (3a) matches.During installation, on water pipe (1), put nut (3), " O " type cushion rubber of band jump ring (3a) successively, sealing strip (5) is twined in end at water pipe (1), and pipe (1) is inserted steel pipe joiner seat (6), nut (3) is tightened at steel pipe joiner seat (6) upward get final product.
