Abstract
The utility model relates to a thin-wall pipe connector structure. A plane surface face is arranged at the rear end of joint internal thread. The end of a connected thin wall tube is made into a flange mouth. A sealing washer is arranged between the plane surface face and the flange mouth. External screw-threads screw nuts in a screwing joint fix the end of the thin wall tube in a joint. The joint comprises multiple channel joints, such as a straight joint, a t-junctor, an angle head, e tc. The utility model has the advantages of reasonable and simple structure, good manufacturability, convenient assembly and disassembly, high sealing performance and reliability, etc., and is especially suitable for the connection of stainless steel thin wall water tubes.
Description
The utility model relates to pipe fitting interconnection technique field, particularly a kind of thin walled tube link structure.
Existing pipe fitting joint comprises straight coupling, tee union, elbow etc., and its joint end car is shaped on internal thread, is attached thereto the pipe fitting end car that connects and is shaped on outside thread, and both directly are threaded, and twines flax silk in the threaded connection place, oil seal varnishes with lacquer.The pipe fitting joint that this traditional tubular union structure connects to is easy to corrosion in the threaded connection place, and mounting or dismounting are difficulty very.For thin-wall pipe, because car system outside thread thereon, so said structure is not suitable for the thin-wall pipe application.
The purpose of this utility model is to provide a kind of thin walled tube link structure simple in structure, makes thin walled tube when installing and using, and mounting or dismounting are convenient, good airproof performance.
The purpose of this utility model is achieved in that a kind of thin walled tube link, comprises joint, thin walled tube, the outside thread nut that is connected with the joint internal thread, and joint internal thread rear portion car is shaped on a flat end face; Thin walled tube end diffusion becomes flange mouth; Between above-mentioned flat end face and flange mouth, be provided with seal washer, between joint internal thread and thin walled tube end, the thin walled tube end be fastened in the joint by the outside thread nut.
Above-mentioned joint comprises multi-way joints such as straight coupling, tee union, elbow.
That advantage of the present utility model is is simple and reasonable, technology capability good, mounting or dismounting are convenient, sealing and reliability height.Be particularly suitable for the usefulness of stainless steel thin-wall water pipe connection.
Fig. 1 is the utility model structural representation.
Be further elaborated this reality is novel by following embodiment.
Referring to shown in Figure 1, this is a kind of stainless steel thin-wall water pipe linkage structure.Straight coupling 1 internal thread rearward end car is made a flat end face 5.Connected stainless steel thin-wall water pipe 4 ends become flange mouth 6 by special purpose machine tool equipment diffusion.Then, put a rubber seal 2 at above-mentioned flat end face 5, and joint 1 is inserted in stainless steel thin-wall water pipe end, flange mouth 6 contacts with rubber seal 2.Outside thread nut 3 is screwed into joint 1 internal thread till flange mouth 6 presses rubber seal 2, and this stainless steel thin-wall water pipe and joint promptly obtain being connected of quick reliable, high sealing.
Claims (2)
1, a kind of thin walled tube link structure comprises joint, thin walled tube, the outside thread nut that is connected with the joint internal thread, it is characterized in that joint internal thread rearward end car is shaped on a flat end face; Thin walled tube end diffusion becomes flange mouth; Between above-mentioned flat end face and flange mouth, be provided with seal washer, between joint internal thread and thin walled tube end, the thin walled tube end be fastened in the joint by the outside thread nut.
