Abstract
The utility model provides a movable joint for thin wall pipes, which is characterized in that one end of a movable joint is provided with a pipe thread inner joint, a conical sealing ring is arranged in an inner chamber and is contacted with the inner conical surface. A plane washer is arranged on the sealing ring, a lock ring is in threaded connection with an end surface in the inner chamber of the movable joint body via the conical surface and is arranged in the movable joint body so as to tightly press the plane washer, and the inner conical surface of the lock ring is also provided with an elastic notch snap ring. When used, the lock ring and the elastic notch snap ring are sheathed on the end of the thin wall pipe and can be connected with the movable joint head. The utility model has the advantages of no threading, convenient connection, good sealing performance and other advantages in pipe connection, and the utility model is suitable for connecting thin wall pipes.
Description
The utility model relates to improved union, particularly a kind of thin-walled movable pipe joint.
In the prior art, the connecting means of pipe is that the end machining with pipe goes out pipe thread, with socket they is linked together then.Yet this method only is applicable to the pipe that tube wall is thicker, for the connection of thin-walled tube, can only adopt welding method to realize because of being difficult to process pipe thread.But there is the low and deficiency such as mounting or dismounting inconvenience etc. of efficiency of construction again in welding method.
The purpose of this utility model be to provide a kind of compact structure, easy and simple to handle, connect the thin-walled movable pipe joint that tubing need not machining screw.
Above-mentioned task is achieved in that this union is by the union body, seal ring, faced washer, elasticity breach snap ring and retainer are formed, one end of union body is provided with a pipe thread spigot, seal ring is a conical seal ring, contact with the internal conical surface of union intracoelomic cavity with its outer conical surface and to place in the union body, the retainer that the outside is provided with bolt die is connected in the inner chamber that places the union body with the internal thread of union body with the screw thread of its external cylindrical surface, faced washer is arranged between seal ring and the retainer, elasticity breach snap ring places in the inner cavity of retainer, and contacts with its taper inner peripheral surface.
The utility model is to use like this: earlier with the retainer cover to thin walled tube, and on the termination point casing of thin walled tube elasticity breach snap ring, on the union body, put into seal ring and faced washer then, the thin walled tube that will be with retainer and elasticity breach snap ring again is inserted in the union body, and allows the screw thread of retainer be connected with the internal thread of union body and screw.Along with constantly precession in the union of retainer, the conical surface of its inner chamber just constantly presses elasticity breach snap ring, and making it tightly to block past thin walled tube can not take off outward.Meanwhile, the interior edge face of retainer also constantly presses faced washer and seal ring, makes seal ring toward interior contraction, tightly encases thin walled tube, makes it to play good seal action.At last, or threeway socket logical with two is connected just and can links together with other pipe with the spigot of union body.This shows, the utlity model has following advantage: tubing need not to connect screw thread in the processing can connect construction, solves the connectivity problem of thin walled tube effectively.In addition, this joint also has compact structure, easy and simple to handle and high efficient construction.
Below in conjunction with accompanying drawing structure of the present utility model is further described
Fig. 1 is the sectional view of a kind of concrete structure of the utility model.
As shown in Figure 1, union body 1 usefulness stainless steel or Cuprum alloy add and form, and are provided with a pipe thread spigot 2 at the one end, process internal thread at the other end.Seal ring 3 is a conical seal ring, contacts in the inner chamber 4 that places union body 1 with the internal conical surface of union body 1 inner chamber 4 with its outer conical surface.Faced washer 5 is close to seal ring 3 and is placed in the union body 1.The external cylindrical surface of retainer 6 has the outside thread with union body 1 screw-internal thread fit, is provided with bolt die 7 on the ring in its outside, so that use spanner that retainer 6 is screwed in the union body 1.Have a taper inner cavity 8 in the inboard of retainer 6.Elasticity breach snap ring 9 contacts with the conical inboard wall of retainer 6 inner cavities 8 with its external diameter and places in the retainer 6.The internal diameter of elasticity breach snap ring 9 should be consistent with the external diameter of thin walled tube, so the utility model can be made into a series of products, with the needs of the thin walled tube that adapts to different-diameter.
