Embodiment
Be clearly and completely described below with reference to embodiment and the accompanying drawing technique effect to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, characteristic sum effect fully.Obviously; described embodiment is a part of embodiment of the present utility model, instead of whole embodiment, based on embodiment of the present utility model; other embodiments that those skilled in the art obtains under the prerequisite not paying creative work, all belong to the scope of the utility model protection.
With reference to Fig. 1 ~ Fig. 5, the utility model is a kind of thread groove formula thin-wall stainless steel tee pipe fitting, the nipple 2 comprising threeway 1 and be connected with threeway 1, the jointing of nipple 2 and threeway 1 is provided with seal ring 32, the outer wall at the another two ends of nipple 2 the other end and threeway 1 is equipped with the outside thread for connecting, being equipped with groove 4 at nipple 2 and threeway 1 near nipple 2 and one end outer wall of the joint of threeway 1, in each groove 4, connecting nipple 2 and threeway 1 by snapping in clip 3.
The threeway 1 that this thread groove formula thin-wall stainless steel tee pipe fitting is provided with is connected by clip 3 with nipple 2, during installation, first connecting tee 1 and nipple 2 are on pipeline, re-use clip 3 threeway 1 is connected with nipple 2, because clip 3 can 360 degree of rotations, tee pipe fitting is installed when connecting and is not subject to the restriction such as angle direction and spatial position, reduce labor intensity and cost, improve installation efficiency and economic benefit.
The outer wall of nipple 2 is positioned at the one end be connected with threeway 1 and is provided with groove 4, the outer wall of threeway 1 is positioned at the one end be connected with nipple 2 and is provided with groove 4, the both sides of clip 3 are respectively equipped with protruding snap ring 35, and each snap ring 35 to snap in two grooves 4 and connecting tee 1 and nipple 2 respectively.The size of two grooves 4 is greater than the width of snap ring 35, thinks that installation reserves surplus.
As the utility model preferred embodiment, clip 3 comprises card lid 33 and lower card lid 34, and upper card lid 33 and lower card lid 34 inside are provided with the cavity placing seal ring, and the sectional view of upper card lid 33 and lower card lid 34 is U-shaped.
The sectional view of upper card lid 33 and lower card lid 34 is U-shaped, and U-shaped lips are snap ring 35, and seal ring is arranged in the cavity of U-shaped bottom, under the clossing pressure of Shang Kagai 33 and lower card lid 34, seals the jointing of threeway 1 and nipple 2.
As the utility model preferred embodiment, upper card lid 33 and lower card lid 34 are bolted.
As the utility model preferred embodiment, bolt adopts round head square neck bolt.
As the utility model preferred embodiment, seal ring 32 is saddle type seal ring.
The sealing lip Full connected tube wall of saddle type seal ring need be ensured.
As the utility model preferred embodiment, the screw thread that threeway 1 and nipple 2 are provided with is circular arc tooth tapered thread.
The feature of circular arc tooth tapered thread is formed overall for tubing wall thickness cold rolling system, realizes the wall thickness such as screw thread wall thickness and tubing and process, do not have the mach surplus of screw thread and waste.
This thread groove formula thin-wall stainless steel tee pipe fitting is mainly used in thin-wall stainless steel tee pipe fitting, comprise a threeway 1, saddle type seal ring, clip 3, half-round head square neck bolt and nut assembly, threeway 1 two ends roll extrusion circular arc tooth tapered thread wherein, another termination is rolling out the groove 4 of an one fixed width and the degree of depth apart from pipe end a distance, this groove 4 is also that overall wall thickness cold rolling forms.At one end roll extrusion circular arc tooth tapered thread of nipple 2, the other end of nipple 2 is at the groove 4 rolling out an one fixed width and the degree of depth apart from pipe end a distance, and the width of groove 4 is slightly wider than the snap ring of clip 3, can adapt to Pipe installing error and adjustment.This unified wall thickness processing mode makes 100% to utilize tubing thickness, saves and decrease the wall thickness of Stainless Steel Tube, reduces the cost of raw material and processing.Respectively there is an annular snap ring 35 at clip 3 two ends, and centre is cast with a cavity to hold saddle type seal ring, and clip 3 makes split type structure, is connected with nut with round head square neck bolt, convenient installation.The groove of threeway 1 and nipple 2 is to the distance of pipe end, and on the pipe to make saddle type seal ring to ride between their respective grooves to tube edge, and its width is slightly wider than saddle type seal ring, can adapt to Pipe installing error and adjustment.
During installation, first the tapered thread in one end tapered thread of nipple 2 and pipeline is coated liquid raw meal belt, and tighten and connect; Again the tapered thread end of two in threeway 1 is coated liquid raw meal belt with the tapered thread in pipeline respectively, tighten and connect, adjust arbitrarily position and angle by in-site installation requirement; Saddle type seal ring is enclosed within the groove end of threeway 1 and the groove end of nipple 2 again, clip 3 is stuck in threeway 1 with in the groove of nipple 2, with round head square neck bolt and nut screwing clamping, so just tee pipe fitting is connected to easily pipeline and has suffered.Because the clip 3 of groove end can 360 degree of rotations, not by the constraint of angle, solve the problem by angular orientation restriction when threeway screw thread is installed.Compared with connecting with one end loose flange, this pipe fitting only connects with a locked clip device and just reaches desirable object, eliminate the operation that loose flange needs welding one section of flange nipple, cost savings 30%, and weight ratio flange is light, have lightweight, cost is low, flexible for installation light, economical imitate, extensive market, be easy to the advantage of popularization.This model utility is optimized combination and Curve guide impeller to flanged tee in the past, groove threeway, screw thread threeway, structure is simple, reliable performance, manufacture simplification, cost reduces, and solves the contradiction between thin-wall stainless steel threeway 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 distortion or replacement are all included in the application's claim limited range.
