Abstract
The utility model relates to the field of heat exchangers, in particular to a U-shaped tube with a locating device. The U-shaped tube with the locating device is characterized in that locating piece limiting welded rings are arranged on the outer sides of straight tubes of two sides of the U-shaped tube, and the two locating pieces are located on the same horizontal plane. Through the adoption of the above scheme, quality and stability during the process that the U-shaped tube is welded with metal tubes through the welded rings are improved.
Description
Technical field
The utility model relates to heat exchanger field, refers in particular to a kind of U-shaped pipe with positioner.
Background technology
heat exchanger is that the heat with certain fluid passes to the equipment of other fluid with certain heat transfer type, for make inside and outside metal tube the fluid thermal exchange enough fully, need enough length, and the restriction of heated exchanger volume, metal tube can not immoderately extend, generally take U-shaped pipe to couple together between each metal tube side by side in heat exchanger, as shown in Figure 1, the straight-tube portion of U-shaped pipe is fastened in two metal tubes, in order to improve air-tightness, also be socketed with weld-ring in the place that U-shaped pipe is connected with metal tube, weld-ring can weld together U-shaped pipe and metal tube after melted by heat.
There is following shortcoming in this kind structure: the size of metal tube is unfixing, and there is error in processing, causes U-shaped pipe to produce deflection, thereby affects welding quality, finally affects the performance of heat exchanger.
Therefore, the inventor makes further research this, develops a kind of U-shaped pipe with positioner, and this case produces thus.
The utility model content
The purpose of this utility model is to provide a kind of U-shaped pipe with positioner, can improve quality and the stability in metal tube when welding of U-shaped pipe and heat exchanger.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of U-shaped pipe with positioner is characterized in that: be provided with the keeper of restriction weld-ring outside the straight tube of U-shaped pipe both sides, and two keepers are positioned at same level.
Further, described keeper is several locating pins, and described locating pin evenly distributes at same cross section.
Further, described locating pin is the locating pin that straight tube from inside to outside convexes to form.
Further, described locating pin is by the locating pin that forms of cutting from lower to upper on straight tube.
Further, described locating pin is respectively four on each straight tube.
Further, described keeper is positioning bar, and the straight tube of described positioning bar and U-shaped pipe is integral structure.
Further, described keeper is positioning step, and described straight tube comprises the upper and lower, and the race diameter on top is greater than the race diameter of bottom, and the junction of upper and lower forms positioning step.
After adopting such scheme, the utility model compared with prior art has the following advantages:
Owing to having added keeper on U-shaped pipe, so weld-ring is inserted in the U-shaped Guan Shihui restriction that is positioned, two straight tubes are symmetrical in the left and right, can be not crooked when U-shaped like this pipe and metal tube welding, and the left and right height is consistent, the quality when having improved the welding of U-shaped pipe and metal tube.

U-shaped pipe 1, straight tube 11, locating pin A21, locating pin B22,
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
As shown in Figure 2, a kind of U-shaped pipe 1 with positioner that the utility model discloses, be respectively equipped with the locating pin A21 of four restriction weld-rings 4 on the straight tube 11 of U-shaped pipe both sides, locating pin A21 be uniform ring on straight tube 11, and the locating pin A21 on left and right straight tube 11 is symmetrical arranged.And locating pin A21 is by adding man-hour, from the mouth of pipe cutting from the bottom up of straight tube 11, arrives and to stop after certain size formedly, adding the degree of depth and the length of processing only need keep cutting man-hour the time, can form required locating pin A21 like this.
During welding, only need weld-ring 4 is inserted in straight tube 11 until meet locating pin A21, in the metal tube 3 of the heat exchanger of then U-shaped pipe 1 being packed into, weld and get final product.
As shown in Figure 3, as the second embodiment of the present utility model, can be by in the straight tube 11 of U-shaped pipe 1, by the application of force from inside to outside, make and convex to form locating pin B22 on straight tube 11, all the other features are all as the first embodiment.
As shown in Figure 4, as the third embodiment of the present utility model, can by be processed to form positioning bar 23 on U-shaped pipe 1 straight tube 11, realize identical effect.
As shown in Figure 5, as the 4th kind of embodiment of the present utility model, form by the pipe end shrink mouth mode with straight tube 11 straight tube 11 that two sections outer ring radiuses differ, the straight tube 11 that wherein the outer ring radius is less is positioned at the bottom, form positioning step 24 in the junction of upper and lower straight tube 11 like this, can realize limiting equally the effect of weld-ring 4.
Above-mentioned is only specific embodiment of the utility model, but design concept of the present utility model is not limited to this, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should belong to the behavior of invading the utility model protection domain.
