Abstract
The utility model discloses a pipe connector easy to weld. The pipe connector comprises two sections of straight pipes which are arranged in an attached mode in parallel. One ends of the two sections of the straight pipes are communicated through a bent section, and the other end of each section of the straight pipe is a welded end. The two sections of the straight pipes comprise a long pipe and a short pipe, so that a first distance between the two welded ends is formed, and welding hand holes are formed in the side wall, away from the long pipe, of the short pipe. By means of the pipe connector and the welding hand holes in the pipe connector, operators can conveniently weld coils with different coil diameters, and great convenience is brought to actual use.
Description
Technical field
The utility model relates to a kind of tube connector that is easy to welding, particularly a kind of tube connector that is provided with welding hand hole.
Background technique
At present, during tubular construction has been widely used in life and has produced, adopt the product of tubular construction as increasing in the demand such as fan coil unit, cooling coil.As shown in Figure 1, for current common snakelike (U-shaped) coiling method, between adjacent two straight tubes, make above-mentioned adjacent straight tube form the turnover of one 180 degree by a bending tube, this coiling method has not only been saved the space that coil pipe occupies in equipment, also can ensure that coil pipe forms a complete runner.
But, due to the restriction of existing technique, this bending tube can not coil moulding with this straight tube conventionally, therefore, in general this bending tube need to be made for link, better simplyly adopt U-shaped link to be connected with straight tube, its Placement is not limit, can adopt pressing to be spirally connected and the mode such as welding, but in the time that coil pipe need to be arranged side by side each other, after coiling completes, the gap between adjacent coil pipe need to be connected, at present common still can leave gap by coil pipe crimping or bonding method between coil pipe, and can not ensure the seamless link between coil pipe.Therefore, adopt the method for welding just to become the one way easily that realizes seamless link.But, the caliber of coil pipe is not quite similar, when the coil pipe on equipment need to be coiled in together side by side, to cause welding in outside time, contiguous two pipe adjacent regions cannot be welded, and when the caliber of coil pipe hour, operating personnel also cannot creep in coil pipe, weld in the gap from inner side to coil pipe.
In sum, claimant is based on the working experience in related domain for many years, be susceptible to, if a kind of tube connector of the operating personnel's of being easy to welding can be provided, by the welding hand hole on tube connector, convenient working personnel weld the coil pipe of various pipe diameter sizes, bring great convenience to actual use.
Model utility content
For solving the problems of the technologies described above, the purpose of this utility model is, a kind of tube connector that is provided with welding hand hole is provided, and by the hand hole on tube connector, with convenient working, personnel weld.
For reaching above-mentioned purpose, a kind of tube connector that is easy to welding of the utility model, it has two parallel two sections of straight tubes that are sticked, wherein one end of two sections of straight tubes is communicated with by a bend section, the other end is welding ends, long tube of these two sections of straight tubes and a short tube, and make between two welding endss to have one apart from l, be provided with welding hand hole at the sidewall away from long tube of short tube.
Preferably, this is 50 ~ 100mm apart from l.
Preferably, the diameter of described straight tube is 60 ~ 200mm.
Preferably, this welding hand hole is rectangular, and its length is L, and width is H, and this length L is between 40cm-120cm.
Preferably, described welding hand hole is located at the welding ends of short tube, is L shaped opening and form a side.
Preferably, this welding hand hole is positioned on the line of centres of length pipe.
Preferably, the part that welding ends is relative with this welding hand hole is interior weld part, and the welding ends that this welding hand hole is adjacent is outside weld portion.
Preferably, described interior weldering portion and outside weld portion have overlap region.
Preferably, this long tube one side is partial in overlap region.
Preferably, this hand hole is circular, oval or semicircle.。
The beneficial effects of the utility model are, by said structure, by the welding hand hole on tube connector, and can adopt the method for interior outside in conjunction with welding, convenient working personnel weld the coil pipe of various pipe diameter sizes, make between adjacent coil pipe, accomplish seamless welding between coil pipe and tube connector, bring great convenience to actual use.

Embodiment
In order to allow above-mentioned and other object of the present utility model, feature and advantage can become apparent, preferred embodiment of the present utility model cited below particularly, and coordinate accompanying drawing, be described in detail below:
The utility model provides a kind of tube connector that is easy to welding, as shown in Fig. 2 A and Fig. 2 B, for the structural representation of the utility model one preferred embodiment, shown in tube connector there are two parallel two sections of straight tubes 1 that are sticked, wherein one end of two sections of straight tubes 1 is communicated with by a bend section 2, after being connected with coil pipe, tube connector shown in making can form a complete runner, the other end of two sections of straight tubes 1 is welding ends 3, wherein, two sections of straight tubes of this of tube connector 1 are a long tube and a short tube, and make between two welding endss to have one apart from l, be provided with welding hand hole 4 at the sidewall away from long tube of short tube, by welding hand hole, convenient working personnel stretch into hand in tube connector, coil pipe is entered to direct row welding.Especially when long tube side is connected with straight tube, can adopt outside welding completely, and can not be subject to the interference of short tube.
Further, this is 50 ~ 100mm apart from l.Preferably, this distance is 80 ~ 100mm.
Further, the diameter of phi of two straight tubes 1 is 60 ~ 200mm.Preferably, described diameter is 159mm.
This welding hand hole can be designed to circle, ellipse or semicircle as required.In the present embodiment, this welding hand hole is rectangular, is arranged at the welding ends 4 of short tube, its length is L, and width is H, thereby forms from the side a L shaped opening, this length L, between 40cm-120cm, just in time can stretch in this welding hand hole operating personnel's hand and welds.
Further, this welding hand hole is positioned on the line of centres of long tube and short tube.Wherein, the part that welding ends 3 is relative with this welding hand hole 4 is interior weld part, and the welding ends that this hand hole is adjacent is outside weld portion, and preferably described interior weldering portion and outside weld portion should have overlap region.Preferably, this long tube one side is partial in this overlap region.By the welding hand hole arranging on this tube connector, operating personnel is in the time welding the coil pipe of different tube diameters, can directly hand be extend in tube connector from welding hand hole 4, can carry out direct seamless welding to the gap place of the gap place of tube connector and coil pipe and two adjacent coil pipes.When the caliber of coil pipe is very little, thereby operating personnel is can not directly enter coil pipe and directly weld time, can adopt this tube connector, can convenient working personnel weld on coil pipe.
Just the above, be only preferred embodiment of the present utility model, when not limiting the utility model practical range with this; Therefore, all simple equivalences of doing according to the utility model claim change and modify, and all should still belong in the scope that the utility model patent contains.
