Embodiment
With reference to Fig. 1 ~ Fig. 6, the utility model is a kind of thread groove formula thin-wall stainless steel elbow pipe fitting, comprise elbow main body 1 and the nipple 2 be connected with described elbow main body 1 one end by clip 3, one end that described elbow main body 1 and nipple 2 are connected with each other is equipped with the groove 4 embedded for clip 3 side, and the other end of described elbow main body 1 and nipple 2 is the section of being threaded 5.
Be connected with pipeline respectively with nipple 2 by elbow main body 1 under this thread groove formula thin-wall stainless steel elbow pipe fitting, by clip 3, the connecting end of elbow main body 1 with nipple 2 is connected again, in elbow main body 1 and nipple 2 connection procedure, clip 3 is connected by groove 4 with elbow main body 1 and nipple 2, clip 3 can carry out 360 degree of rotations, the connection procedure making pipe fitting, can the installation carrying out elbow screw thread of more convenient and quicker by the constraint, more flexible of angle.
As the utility model preferred embodiment, clip 3 comprises shell ring body 31 and is positioned at the clip limit 32 of the embedded groove 4 that described shell ring body 31 both sides are arranged downwards, forms the cavity that can hold seal ring 6 inside the clip limit 32 of described shell ring body 31 and both sides.
As the utility model preferred embodiment, seal ring 6 is saddle type seal ring, and described seal ring 6 comprises top and is close to the seal ring 61 of shell ring body 31 and is positioned at the saddle side ring 62 being close to elbow main body 1 and nipple 2 connecting end respectively in seal ring 61 both sides.
As the utility model preferred embodiment, clip 3 comprises the clip semi-ring 33 docked each other both sides, and the both sides of clip semi-ring 33 described in two are equipped with clip shoulder 34, and clip semi-ring 33 described in two forms clip 3 by clip shoulder 34 docking of both sides.
As the utility model preferred embodiment, the section of being threaded 5 is provided with circular arc tooth tapered thread, and circular arc tooth tapered thread is formed by the overall cold breakdown compacting of tubing.
The distance of groove 4 to the tube edge on elbow main body 1 and nipple 2, on the pipe wanting to make the saddle side ring 62 of seal ring 6 both sides ride between their respective groove 4 to tube edges, and its width is slightly wider than the seal ring 6 of saddle type, so that Pipe installing error and adjustment can be adapted to, and the width of groove can make the clip limit 32 on clip 3 both sides be stuck in two grooves 4 of elbow main body 1 and nipple 2 simultaneously, the width of groove 4 is slightly wider than clip 3, can adapt to Pipe installing error and adjustment.
Respectively there is a clip limit 32 at clip 3 two ends, and centre is cast with a cavity to hold the seal ring 6 of saddle type, and clip 3 makes split type structure, with round head square neck bolt and nut installation easy to connect.
During installation, first the section of being threaded on nipple 2 and the tapered thread in pipeline are coated liquid raw meal belt, and tighten and connect, again the tapered thread in the tapered thread of elbow main body 1 and pipeline is coated liquid raw meal belt, tighten and connect, position and angle is adjusted arbitrarily by in-site installation requirement, last assembly ring 3, the seal ring 6 of saddle type is enclosed within the groove 4 of elbow main body 1 and the groove 4 of nipple 2, the groove 4 li of elbow main body 1 and nipple 2 is stuck in clip 3, with round head square neck bolt and nut screwing clamping, so just elbow is connected to easily pipeline to have suffered.
Because the clip 3 of groove end can 360 degree of rotations, so not by the constraint of angle, this just solves the angular orientation problem that elbow screw thread is installed.
This pipe fitting is optimized combination and Curve guide impeller at flanged bend in the past, groove elbow, threaded elbow, and structure is simple, reliable performance, manufacture simplification, and cost reduces, and solves the contradiction between thin-wall stainless steel elbow price and flexible for installation, practicality.
Certainly, the invention is not limited to above-mentioned mode of execution, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
