Abstract
The utility model relates to a cutting ferrule type copper pipe joint, which comprises a joint body 6, a locking nut 5 arranged at the end of the joint body, a cutting ferrule 3 arranged between the joint body and the nut, etc. The joint body, the locking nut and the cutting ferrule are all made of copper. The utility model is characterized in that the outer surface of the cutting ferrule forms an arc shape and the arc core of the arc offsets from the geometric centroid of the cutting ferrule. The utility model has the advantages of reasonable structure design, and compared with the existing cutting ferrule, the utility model decreases the curvature radius of the spherical surface of the cutting ferrule, and increases the convexity of the cutting ferrule in correspondence. When connected with a pipe, the utility model can make cutting ferrule plastically deformed, which enhances the sealing property and enlarges the reliability of the connection.
Description
The utility model relates to a kind of FERRULETYPE copper tube joint, belongs to the pipe joint technical field.
The supporting FERRULETYPE copper tube joint of existing and copper pipe and Plastic coated copper pipe mainly is made of joint body, lock nut, cutting ferrule etc.The outer surface of its cutting ferrule is spherical, the centre of sphere of sphere is the geometric centroid of cutting ferrule, the center that is the centre of sphere and cutting ferrule coincides, the spherical outer surface of this kind cutting ferrule is more smooth, when being connected with pipe, under same pretightening force, cutting ferrule is not easy to take place elasto plastic deformation, it is not really tight that pipe and joints body and cutting ferrule are cooperated, thereby influenced the sealability and the connection reliability of pipe joint.For big specification pipe joint, as adopting spherical outer surface the cutting ferrule width is strengthened, thereby cause lock nut also must strengthen, increase manufacture cost.
The purpose of this utility model provides a kind of reasonable in design, connects reliably the FERRULETYPE copper tube joint of good airproof performance.
The utility model is the FERRULETYPE copper tube joint, comprise joint body, place the lock nut of joint body end, place cutting ferrule between joint body and the nut etc., the material of joint body and lock nut and cutting ferrule is copper, the outer surface that it is characterized in that described cutting ferrule is an arc, the geometric centroid of its arc core skew cutting ferrule.Described joint body end is provided with outside thread, is provided with the internal thread that matches with joint body in the lock nut.The inner chamber afterbody of described lock nut is tapered, and the end of joint body is inner conical.
The utility model reasonable in design, the outer surface of its cutting ferrule is designed to arc, compare with former cutting ferrule, reduced the radius of curvature of cutting ferrule appearance sphere, increased the height of projection of cutting ferrule relatively, when being connected with pipe, can make cutting ferrule generation plastic deformation effectively, make the inner chamber afterbody conical surface, joint body inner end taper and cutting ferrule cambered surface and the tight pressing of pipe of lock nut, improved sealing, increased connection reliability, the also corresponding height that has shortened cutting ferrule height and lock nut has reduced cost.The utility model can comprise that nominal diameter is the straight connector of Φ 15～Φ 50mm, elbow, and the pipe joint of types such as tee union can be widely used in copper pipe, Plastic coated copper pipe, mould the connection of covering tubing such as aluminum pipe.
Accompanying drawing has provided structural representation of the present utility model.
Fig. 1 is an overall structure half sectional view of the present utility model.
Fig. 2 is the structure sectional view of cutting ferrule described in the utility model.
Fig. 3 is the structure sectional view of cutting ferrule in the existing pipe joint.
The utility model will be further described below in conjunction with embodiment:
The utility model is mainly by joint body 6, cutting ferrule 3, lock nut 5 formations such as grade, the inner chamber afterbody tapered 2 of lock nut 5, the end of joint body 5 is inner conical 4, its cutting ferrule outer surface is an arc, arc core A is offset from cutting ferrule geometric centroid a, the radius R of arc-shaped outer surface that is cutting ferrule is less than the radius R ' (as shown in Figure 2) of the maximum cylindrical of cutting ferrule, and the outer surface of the cutting ferrule of pipe joint of the prior art is spherical, its centre of sphere A ' is the geometric centroid a ' of cutting ferrule, and promptly the radius of a ball equals cutting ferrule radius γ (as shown in Figure 3).
During installation, earlier lock nut 5 and cutting ferrule 3 successively are placed in and wait to join two pipes together on 1, then pipe 1 is inserted in the joint body 6, screw lock nut 5, the internal thread of tight locknut and the outside thread of joint body end are meshed fully, the conical surface 2 of locking nut inner chamber afterbody and the inner conical surface 4 of joint body end then respectively with the tight pressing of cutting ferrule cambered surface, realize that promptly pipe joint is connected with the reliable of pipe.Present embodiment is tested through practical application, is example with the 15mm pipe joint, and under the same conditions, under same impacting force effect, its connection reliability can double above, and sealability also significantly increases.
Claims (3)
1. FERRULETYPE copper tube joint, comprise joint body (6), place the lock nut (5) of joint body end, place the cutting ferrule (3) between joint body and the nut, the material of joint body and lock nut and cutting ferrule is copper, the outer surface that it is characterized in that described cutting ferrule is an arc, the geometric centroid of its arc core skew cutting ferrule.
