Abstract
The utility model has been announced a kind of small-bore gas riser welding to mouthpart, comprise and be fixed on determining semi-steel pipe and determining with described the moving semi-steel pipe that semi-steel pipe matches on connecting rod, described moving semi-steel pipe arranged outside has the first spigot nut, on described connecting rod, be provided with the second spigot nut, adjusting screw(rod) one end is through the second spigot nut, coordinate with the first spigot nut, the other end is connected with regulating handle.The utility model is simple in structure, convenient at high building welded and installed gas riser pipeline, is applicable to multiple common small-bore gas riser welding, improves the concentricity of small-bore pipeline and pipe fitting welding simultaneously, improves workman's operating efficiency and work quality.
Description
Technical field
The utility model relates to a kind of small-bore gas riser welding to mouthpart.
Background technology
Pipe gas has become people's one of topmost energy of living, by riser tube by natural gas transport to user family, for people's life provides great convenience.But because fuel gas exists certain danger, so very high to the seal for pipe joints requirement of transport gas, the seam of pipeline enclosure can not be leaked gas, specification requirement to welding is higher, guarantee not misalignment as far as possible, when pipe fitting and standpipe welding, also will guarantee concentricity as far as possible.
Gas riser generally designs by the flue in kitchen, be generally corner, when the gas riser of high building is installed, the standpipe of 3 meters of long left and right needs to weld after vertical direction docking, is difficult to counterpart accurate, be difficult to guarantee weld the in the situation that of misalignment seldom, increased welding difficulty, light with the manual counterpart of workman, be difficult to precisely and need many people to coordinate to lose time, lost labor, efficiency be not high, traditional welding counterpart body is long-pending larger, complicated operation, is not easy to carry and use.
The pipe fitting external diameter of gas steel pipeline is slightly larger than the external diameter of the steel pipe of identical caliber, and easy decentraction when steel pipe pipe fitting and steel pipe riser welding, affects welding quality, affects safe way.
Utility model content
The utility model object is that the defect that exists for prior art provides a kind of and is easy to carry, the easy-operating gas riser welding in little space is to mouthpart.
The utility model for achieving the above object, adopt following technical scheme: a kind of small-bore gas riser welding is to mouthpart, comprise and be fixed on determining semi-steel pipe and determining with described the moving semi-steel pipe that semi-steel pipe matches on connecting rod, described moving semi-steel pipe arranged outside has the first spigot nut, on described connecting rod, be provided with the second spigot nut, adjusting screw(rod) one end, through the second spigot nut, coordinates with the first spigot nut, and the other end is connected with regulating handle.
preferably, at described moving semi-steel pipe or describedly determine semi-steel pipe inner side rubber sheet gasket is set.
The beneficial effects of the utility model: this is simple in structure to mouthpart, are not only easy to carry, little space easy operating, and can improve the welding precision of high building welding gas riser pipeline, reduce misalignment, improve pipe laying workman's operating efficiency.In semi-steel pipe inner side, increase rubber sheet gasket, by adjusting screw(rod), adjust the spacing of two semicircles, make this equipment go for the gas riser steel pipe of multiple caliber, simultaneously by adjusting quantity, the position of pad, can guarantee when Steel pipe and fitting welds concentric.
Accompanying drawing explanation
Fig. 1 structural representation of the present utility model.
The specific embodiment
Figure 1 shows that a kind of small-bore gas riser welding, to mouthpart, comprises location semi-steel pipe 1, adjusting screw(rod) 2, the first spigot nut 3, connecting rod 4, regulates handle 5, small-caliber steel pipe to be welded 6, the second spigot nut 7.Described location semi-steel pipe 1 is two semi-steel pipes, determine semi-steel pipe and moving semi-steel pipe, determine semi-steel pipe left side and connecting rod 4 welding, moving semi-steel pipe right side and the first spigot nut 3 welding, described adjusting screw(rod) 2 coordinates with two spigot nuts, weld with regulating handle 5 on right side, firmly convenient while regulating handle 5 to use for adjusting screw(rod), during two small-caliber steel pipes 6 of welding, first hold and regulate handle 5 rotation adjusting screw(rod)s 2, the distance that makes to locate between semi-steel pipe 1 becomes large, to by shown in Fig. 1, assemble mouthpart and small-bore standpipe steel pipe, by two small-caliber steel pipe 6 outer wall alignment to be welded, after misalignment is as much as possible little, opposite spin adjusting screw(rod) 2, make to locate semi-steel pipe 1 and clamp two small-caliber steel pipes 6 to be welded, in clamping process, note two small-caliber steel pipes to be welded 6 misalignment not as far as possible, welder welds after two points, just can unload counterpart device, welder continues two small-caliber steel pipes 6 to be welded to weld.The welding of steel pipe and steel pipe fittings is the same process, and only, because steel pipe is compared with the steel pipe fittings of same caliber, external diameter is smaller, thus at two the semi-steel pipe inwalls of that end that press from both sides steel pipe, add appropriate rubber sheet gasket, just can be the same with steel-pipe welding; In semi-steel pipe inner side, increase rubber sheet gasket, by adjusting screw(rod) 2, adjust the spacing of two semicircles, also can be so that counterpart device can be applicable to the steel-pipe welding of different bores.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
