Abstract
This utility model discloses a removable joint, including a joint, a nut and a ball joint. One end of the joint is the an external thread which is connected with a tube, and the other end is an screw thread connected with the ball joint, a tapered hole is provided in the joint; the ball head of the ball joint is matched with the tapered hole, the nut is in the back of the ball head of ball joint, the nut and ball joint adopt pressing connection, and the other end of ball joint is the screw thread which is connected with the other tube. Because the sealing is performed by connecting ball joint with the tapered hole, the problem that there is sealing element in existent joint and the aging and abrasion of sealing element will probably become hazard of leakage is solved; the method of matching ball joint with tapered hole is adopted which removes the sealing element and increases the service life; moreover, the structure is simple and use is convenient.
Description
Technical field
The utility model belongs to a kind of pipeline connection fittings, and being mainly used in lives between the threaded fitting of various calibers connects.
Background technique
At present used pipe connects union, the general threaded coupling of only establishing a pair of identical diameter at the union two ends, usually only be applicable to the connection between the threaded fitting of same diameter. but in actual use, needing often to occur between internal thread tube piece and the inside/outside threaded fitting between connection situation alive, sometimes also can run into the connection situation alive that needs the conversion caliber, therefore, thereby often need to increase other pipe connection fittings and realize above-mentioned connection. increased the actual amount and the construction operation amount of pipe fitting, increased the resistance of pipeline, and having increased to become the number of ports that leaks hidden danger, also have many Sealings that in the middle of joint, have, and the aging and wearing and tearing of Sealing have increased the hidden danger that might become leakage, need a kind of union that can directly realize connection alive between various diameter thread pipe fittings, to remedy the deficiency of prior art for this reason.
Summary of the invention
The utility model provides a kind of union that can directly realize connection alive between various diameter thread pipe fittings.
For achieving the above object, the technical solution of the utility model is:
A kind of union comprises joint, nut and spherical joint.One end of joint is the outside thread that joins with pipe, the other end is the screw thread that is connected with spherical joint, there is a cone shape hole in portion within it, the bulb of spherical joint cone shape hole therewith matches, nut is in the bulb back of spherical joint, nut and spherical joint adopt to withhold and are connected, and at the other end of spherical joint a screw thread that links to each other with pipe are arranged.
The utility model seals owing to adopting spherical joint to link to each other with cone shape hole.Having solved in the existing joint has Sealing, and the aging and wearing and tearing of Sealing may become the problem of the hidden danger of leakage, the method that now adopts spherical joint and taper hole to match, removed Sealing, increase working life, and had characteristics such as simple in structure, easy to use.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 1, a kind of union comprises joint 1, nut 2 and spherical joint 3.One end of joint 1 is the outside thread that joins with pipe, the other end is the screw thread that is connected with spherical joint 3, there is a cone shape hole in portion within it, the bulb of spherical joint 3 cone shape hole therewith matches, nut 2 is in the bulb back of spherical joint 3, nut 2 and spherical joint 3 adopts to withhold and is connected, and is the screw thread that links to each other with another pipe at the other end of spherical joint 3.Because adopting spherical joint 3 to link to each other with cone shape hole seals.Having solved in the existing joint has Sealing, and the aging and wearing and tearing of Sealing may become the problem of the hidden danger of leakage, and the method that now adopts spherical joint 3 and taper hole to match has been removed Sealing, has increased working life.
