Abstract
The utility model discloses a connecting structure for a metal pipe fitting. According to the technical scheme, the connecting structure for the metal pipe fitting mainly comprises a pipe fitting body and a joint body; the pipe fitting body is provided with a pipe fitting connecting part, the joint body is provided with a joint connecting part, and the pipe fitting connecting part and the joint connecting part are matched in an inserted and connected mode; the joint connecting part is provided with a main channel, and the pipe fitting connecting part can be inserted in the main channel in a connected mode; the pipe fitting connecting part is provided with an auxiliary channel which is connected with the main channel in a communicated mode; the portion where the pipe fitting connecting part and the joint connecting part are matched in the inserted and connected mode forms a welding area. By the adoption of the technical scheme, a traditional structure that welding is only conducted at the connecting edge is changed into the whole connecting parts are connected in a welding mode, the welding area is enlarged, the steadiness and reliability of the welding area are improved, and therefore the metal pipe fitting comprising the connecting structure has high shock resistance and tensile resistance and does not loose or fall or leak easily.
Description
Technical field
The utility model relates to a kind of pipe fitting, and more particularly, it relates to a kind of linkage structure of metal pipe element.
Background technique
Metal pipe element is widely used link in drinking water system, running water system, heating system, vapour system, industry oil guard system and industrial tracheal system, is applicable to the pipeline connections such as water, oil, gas.
The safest in the metal pipe element Placement, the most reliable Placement is welded to connect beyond doubt.But for example spigot and socket type is welded to connect existing several Placement or dock is welded to connect, and all has certain defect, especially for the welding of thin-wall metal pipe.It is to weld after the welding ends of a pipe fitting to be welded is inserted to the tube chamber of another pipe fitting welding end to be welded that spigot and socket type is welded to connect, and only in the end portion of pipe fitting welding end to be welded, welds.The dock welding connecting mode is that two pipe fittings to be welded are directly docked, and goes out to weld at docking port.These two kinds of welding manners, because the contact position of welding is too small, make metal pipe element in actual applications, and shock resistance and pull resistance intensity are all inadequate, as easy as rolling off a logly gets loose, the phenomenon such as leakage.
The model utility content
Deficiency for the prior art existence, the purpose of this utility model is to provide a kind of linkage structure of metal pipe element, adopt the metal pipe element welding of this linkage structure solid and reliable, thereby guarantee that metal pipe element has high-intensity shock resistance and pull resistance, be difficult for getting loose, the phenomenon such as leakage.
For achieving the above object, the utility model provides following technological scheme: a kind of linkage structure of metal pipe element, comprise pipe fitting body and fittings body, pipe fitting body and fittings body are respectively equipped with pipe fitting joint and the joint joint of pegging graft and coordinating, the joint joint is provided with the main passage of pegging graft for the pipe fitting joint, the pipe fitting joint is provided with the subaisle be connected with the main passage conducting, and the position coordinated of pegging graft between described pipe fitting joint and joint joint forms welding region.
By adopting technique scheme, traditional only connected to edge's welded structure, changing whole connection part into all takes welding manner to connect, strengthened the zone of welding, steadiness and the reliability of welding region have been improved, thereby make, adopt the metal pipe element of this linkage structure to have high-intensity shock resistance and pull resistance, be difficult for getting loose, the phenomenon such as leakage.
The utility model further is set to: the corresponding all structure settings twist of welding region place of described pipe fitting joint and joint joint.
By adopting technique scheme, helical structure can prevent effectively that pipe fitting joint and joint joint break away from mutually, further improve steadiness and the reliability of welding region.
The utility model further is set to: described fittings body can be connecting body, the connecting body of elbow-shaped or the connecting body of three-way type of straight-through shape.
By adopting technique scheme, the selectable kind of fittings body is various, has greatly improved the practicability of the utility model linkage structure.
The accompanying drawing explanation
Fig. 1 is the linkage structure embodiment's of the utility model metal pipe element structural representation.
Embodiment
With reference to Fig. 1, the linkage structure embodiment of the utility model metal pipe element is described further.
A kind of linkage structure of metal pipe element, comprise pipe fitting body 1 and fittings body 2, pipe fitting body 1 and fittings body 2 are respectively equipped with pipe fitting joint 11 and the joint joint 21 of pegging graft and coordinating, joint joint 21 is provided with the main passage 22 of pegging graft for pipe fitting joint 11, joint joint 21 is provided with the subaisle 12 be connected with main passage 22 conductings, and the position coordinated of pegging graft between described pipe fitting joint 11 and joint joint 21 forms welding region 3.
By adopting technique scheme, traditional only connected to edge's welded structure, changing whole connection part into all takes welding manner to connect, strengthened the zone of welding, steadiness and the reliability of welding region 3 have been improved, thereby make, adopt the metal pipe element of this linkage structure to have high-intensity shock resistance and pull resistance, be difficult for getting loose, the phenomenon such as leakage.
The corresponding welding region of described pipe fitting joint 11 and joint joint 21 3 places all twist the structure setting (it should be noted that herein, the corresponding welding region of pipe fitting joint 11 and joint joint 21 3 places linearly type structure arrange, in order to prevent that effectively pipe fitting joint 11 and joint joint 21 break away from mutually, further improve steadiness and the reliability of welding region 3, the present embodiment is preferred, the all structure settings twist of the corresponding welding region of pipe fitting joint 11 and joint joint 21 3 places, can reach this effect, also has zigzag fashion, the structures such as spirality).
Described fittings body 2 can be connecting body, the connecting body of elbow-shaped or the connecting body of three-way type of straight-through shape.By adopting technique scheme, the selectable kind of fittings body 2 is various, has greatly improved the practicability of the utility model linkage structure.
Claims (3)
1. the linkage structure of a metal pipe element, comprise pipe fitting body and fittings body, pipe fitting body and fittings body are respectively equipped with pipe fitting joint and the joint joint of pegging graft and coordinating, the joint joint is provided with the main passage of pegging graft for the pipe fitting joint, the pipe fitting joint is provided with the subaisle be connected with the main passage conducting, it is characterized in that: the position coordinated of pegging graft between described pipe fitting joint and joint joint forms welding region.
