Abstract
The utility model discloses a welding seam thin-wall stainless steel tube connection structure, which is characterized in that the end of stainless steel tube is provided with an open convex arc, a sealing ring is arranged on one side of the open convex arc close to tube opening and then is connected by connection member. The utility model has the following advantages that the structure of open convex arc can prevent the tube from cracking at the welding seam, sealing ring and flange or other tubes are used to perform the connection, the structure has convenient disassembly, rapid connection, firmness and good sealing performance, the thin-wall stainless steel tube connection method of the structure is convenient, firm and reliable, and can improve the endurance of the tube.
Description
Technical field
The utility model relates to the technical field of Stainless Steel Tube, more particularly relates to the technology that the weld seam thin-wall stainless steel connects.
Background technique
The thin-walled stainless steel tube of weld seam and the Placement between the pipe fitting are arranged, be applicable to liquid, gas transmission pipeline field.Late nineteen nineties; the pipeline that thin-wall stainless steel has been applied topically to China's building water supply and has directly drunk water, reaction is good, therefore; " building water supply tubing finally can return to the epoch of metal tube to relevant expert's prophesy ", thin-wall stainless steel is one of best first-selected tubing of combination property.Owing to there is the weak link of the thin-walled stainless steel tube of weld seam to be its weld seam, therefore to avoid damage to pipe welding seam, also to solve thin-walled stainless steel tube connect complicated, easily come off, the problem of sealing difference.At present, thin-walled stainless steel tube on the market is because the technical requirements and the cost requirement of weldless thin-wall stainless steel is higher relatively, so mainly so that the stainless steel pipeline of weld seam to be arranged, and its Placement is based on clamp-press type, welding type and groove type.Its deficiency of clamp-press type and welding type is that its installation requirement is relative higher, and is difficult to dismounting after installing; Its deficiency of groove type is that its stretching resistance is lower, occurs the phenomenon that gets loose easily, is in the damage that then is prone to when connecting processing pipe welding seam for pipe welding seam, thereby influences sealability.
Summary of the invention
The purpose of this utility model is exactly that provide for the deficiency that solves prior art a kind of can avoid the pipe welding seam damage, and the linkage structure that the weld seam thin-wall stainless steel is arranged easy to connect, firm, good seal performance.
The technical solution that the utility model adopts in order to solve the problems of the technologies described above is as follows:
A kind of linkage structure that the weld seam thin-wall stainless steel is arranged is characterized in that steel tube head is avoided the weld joint and is provided with the opening convex arc, and the opening convex arc is provided with seal ring near the pipeline opening segment pipe, and opening convex arc opposite side pipeline is provided with connector element.
Described opening convex arc is being for avoiding the weld seam pipeline place protuberance outer convex surface band more than a section or a section, and described evagination is worn length greater than long half of pipe circumference.
Described opening convex arc is the some distribution salient points formations that are distributed on the pipe circumference and avoid weld seam.
Described connector element can be flange, also can be other connection pipe fitting.
Described seal ring is a cushion rubber.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: adopt and avoid pipe welding seam protuberance opening convex arc, the explosion phenomenon that such pipeline has avoided the weld joint might occur behind protuberance; Fitted seal circle and flange connect or other pipe fitting connection again, have detachable and convenient disassembly, easy to connect quick, firm, good seal performance; The thin-wall stainless steel Placement easy installation and removal of this structure, solid and reliable, improve the pipeline useful life longevity.

Embodiment
By Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, the linkage structure of this thin-wall stainless steel, be provided with opening convex arc 2 at steel tube head, opening convex arc 2 is provided with blind flange 4 away from the pipeline opening segment pipe, and the opposite side pipeline of opening convex arc 2 is provided with cushion rubber 6, and the flange of blind flange 4 is close to opening convex arc 2, blind flange 4 is provided with tapped hole 8, adopt bolt 7 to be connected with the flange 5 of that end of pipe end, described cushion rubber 6 and flange 5 tight contact matching play seal action.Described opening convex arc 2 and cushion rubber 6 are all between blind flange 4 and flange 5.
By Fig. 1, Fig. 2 and shown in Figure 3, above-mentioned opening convex arc 2 can be various ways, avoiding the outer convex surface band that weld seam 3 places are provided with one section certain-length at the segment port of pipeline 1 among Fig. 1 is opening convex arc 2, and described outer convex surface strip length is generally greater than half of pipeline 1 circumferential length.Avoiding the outer convex surface band that weld seam 3 places are provided with two sections certain-lengths at the segment port of pipeline 1 among Fig. 2 is opening convex arc 2, and described outer convex surface strip length is generally greater than half of pipeline 1 circumferential length.Among Fig. 3, with same reason three sections outer convex surface bands being set is opening convex arc 2.The outer convex surface band of multistage is provided with by same reason, and described opening convex arc can also constitute for the some distribution salient points that are distributed on the pipe circumference and avoid weld seam.
By shown in Figure 4, the erection sequence that pipeline connects, in pipeline 1, be inserted in blind flange 4 earlier, follow the position that convex arc 2 covers with fastening flange outside the segment port of pipeline 1 is avoided weld seam 3 places protuberance, between opening convex arc 2 and pipeline opening, be inserted in cushion rubber 6 again, after connecting with flange 5 and blind flange 4 at last, form cushion rubber 6 and play seal action with tight contact of flange 5.
In the foregoing description, the connection of thin-wall stainless steel of the present utility model can be the connection of other pipe fitting, and other structure is the same.
