Abstract
The utility model relates to a gas meter joint structure. The gas meter joint adopts the structure that a sealing solder layer (4) is arranged between a sealing cover (1) and an upper casing (2), and a sealing solder layer (5) is arranged between the upper casing (2) and the joint (3). When in use, the joint deformation is slight, the structure is smooth and artistic, the production operation is simple and safe, the production efficiency is high, and the quality is stable.
Description
Technical field
The utility model relates to a kind of structure of gas meter joint.
Background technology
Every gas meter, flow meter upper casing all is connected with two joints, is used for being connected with gas piping, realizes the metering to user's gas transmission.Intensity, sealing, the reliability that two joints connect is related to user's safety.Present domestic gas meter, flow meter joint generally adopts cold riveting with being connected of upper casing, O-ring seal on the fitting sleeve is put into the pilot hole of counterdie, with the punching press on joint of upper casing hole flanging flange sleeve upper gasket back cover.Before the production, be according to the joint of different batches examination riveting, satisfy intensity, the sealing of joint by the shut height of adjusting punch die, so the consistance of joint quality is relatively poor.In the production, all than higher, production efficiency is low to accuracy requirement, the operator's of riveted joint mould and riveted joint workpiece requirement.
The utility model content
At above-mentioned drawback, the utility model provides a kind of version of gas meter joint, between seal closure 1 and the upper casing 2 between Packed solder layer 4, upper casing 2 and the joint 3 with Packed solder layer 5.
Further mode is that solder layer 4 and solder layer 5 are commaterial.
Further mode is solder layer 4 and solder layer 5 for being with solder fusing back formation.
By further mode is that solder layer 4 and solder layer 5 are copper base solder.
When using this kind structure, because as long as solder is heated, utilize the wetting mother metal of liquid solder, fill the play movement and with mother metal counterdiffusion mutually, weldment is fused into one, the fusing point that heating-up temperature only is higher than solder is significantly less than the fusing point of mother metal, little, the smooth and beautiful appearance of joint distortion, and simple to operate, safety, production efficiency height, steady quality.
Description of drawings
Fig. 1: the utility model structural representation.
Embodiment
On two locating shafts of lifting table, after loading onto seal closure 1, copper base solder layer 4, upper casing 2, copper base solder layer 5, joint 3 from top to bottom, press lifting button rising lifting table, make sensing apparatus induction coil cover entangle joint and near upper casing 2,0.001s ~ 99.99s starting equipment is heated to solder about 800 ℃ by the oscillation frequency 30 ~ 150Kz that sets, heat time heating time, utilize the wetting mother metal of liquid solder, fill the play movement and with mother metal counterdiffusion mutually, weldment is fused into one.Form the utility model as shown in Figure 1.
The utility model is not limited to the foregoing description; in design scope of the present utility model; the description of book according to the above description, those of ordinary skill in the art also can make some conspicuous changes, but these changes all should fall within the protection domain of the utility model claim.
Claims (4)
1, a kind of structure of gas meter joint is characterized in that: between seal closure (1) and the upper casing (2) between Packed solder layer (4), upper casing (2) and the joint (3) with Packed solder layer (5).
2, according to the structure of the described gas meter joint of claim 1, it is characterized in that: described solder layer (4) and solder layer (5) are commaterial.
3, according to the structure of the described gas meter joint of claim 2, it is characterized in that: described solder layer (4) and solder layer (5) are for forming solder fusing back.
4, according to the structure of the described gas meter joint of claim 3, it is characterized in that: described solder layer (4) and solder layer (5) are copper base solder.
