Abstract
The utility model discloses a corrugated pipe joint. The corrugated pipe joint comprises a joint, a rolling sleeve and an outer joint, wherein the rear end part of the joint is inserted into a corrugated pipe and is welded with the corrugated pipe; the rolling sleeve is sleeved outside a pipe sleeve outside the corrugated pipe and is fixed with the middle part of the joint through rolling; the outer joint is sleeved at the front end of the joint; the rolling part at the rear end of the outer joint is fixed with the rolling sleeve through rolling; the rear end part of the joint serves as a welding part connected with the corrugated pipe in a welding manner; a sealing connection part is arranged at the front end of the joint; and a sealing ring is arranged between the sealing connection part and the outer joint. The joint is firmly welded with the corrugated pipe, and the pipe sleeve outside the corrugated pipe is firmly rolled on the joint through the rolling sleeve, so that even if the corrugated pipe and the joint are damaged, the pipe sleeve is firmly connected with the joint so as to achieve a temporary protection effect. Furthermore, the outer joint is connected with the joint in a rolling manner, so that the joint with the same specification is adopted, and outer joints with different specifications or different connection manners can be selected according to demands.
Description
Technical field
The utility model belongs to the tube connection piece technical field, is specifically related to a kind of corrugated pipe connector structure technology.
Background technique
Bent metal bellows generally need be at two end part jointing so that be connected with equipment more easily; Outside bellows, also can increase the metal pipe box in addition with the protection bellows; The corrugated pipe connector place structure of existing technology is comparatively fragile; Damage easily, there is certain pressure inside during owing to the bellows working state, if the explosion of corrugated pipe connector place will produce danger.
Summary of the invention
The purpose of the utility model is: to the deficiency that the corrugated pipe connector joint of existing technology is damaged easily, a kind of rational in infrastructure, soundness and safe corrugated pipe connector are provided.
For realizing the purpose of the utility model, adopt following technological scheme to be achieved: a kind of corrugated pipe connector, include joint, roll to connect and overlap and socket, described joint rearward end is inserted in the bellows and with bellows and is welded; The outer pipe box of bellows is arranged with outward to roll and connects cover, rolls to connect to overlap and passes through rolling fixing with the joint middle part; The joint front end sleeve is provided with socket, the rolling the portion of connecing and roll that to connect cover rolling fixing of socket rear end.
As preferred version: the weld part of described joint rearward end for being weldingly connected with bellows, the joint front end is provided with the portion of being tightly connected, and is tightly connected to be provided with seal ring between portion and the socket.
As preferred version: described socket front end is a spiro union portion.
Compared with prior art; The beneficial effect of the utility model is: because joint and bellows firmly weld; And the outer pipe box of bellows connects cover and firmly rolls and be connected on the joint through rolling, like this, even bellows occurs damaging with the joint; Pipe box still firmly is connected with joint, can play interim protective action.In addition, socket is connected with joint is rolling, and joint uses specification of the same race, and socket can be selected different size or different Placements as required for use.

Embodiment
According to accompanying drawing the embodiment of the utility model is done a detailed explanation below.
According to shown in Figure 1, the described a kind of corrugated pipe connector of present embodiment includes joint 3, rolls and connect cover 4 and socket 5, described joint 3 rearward end insert in the bellows 1 and with bellows 1 welding; The outer pipe box of bellows 12 is outer to be arranged with to roll and to connect cover 4, rolls to connect cover 4 and joint 3 middle parts through rolling fixing; Joint 3 front end sleeves are provided with socket 5, the portion of connecing 51 of rolling of socket 5 rear ends with roll that to connect cover 4 rolling fixing.
The described front end of each parts refers to the side away from bellows 1 port, and the rear end refers to the side near bellows 1 port.
Described joint 3 rearward end are the weld part 31 that is weldingly connected with bellows 1, and joint 3 front ends are provided with the portion of being tightly connected 32, are tightly connected to be provided with seal ring 6 between portion 32 and the socket 5.
Described socket 5 front ends are spiro union portion 52.The spiro union portion 52 of socket 5 can be selected external thread piece or inner thread piece according to actual needs for use.
Described roll connect the cover 4 rolling completion after; Can connect cover 4 outer surfaces and carry out polishing and handle rolling; Then again the portion of connecing 51 of rolling of described socket 5 is run away to roll to connect on the cover 4 and be rolled, like this, joint 3 connects cover 4, pipe box 2, socket 5 and all connects as one very securely with rolling.
During assembling, with joint 3 and bellows 1 welding, put pipe box 2 earlier; Put again to roll and connect cover 4; Pipe box 2 and joint 3 middle parts are rolled, then to roll connect cover 4 peripheries and carry out polishing after, put seal ring 6 in the portion that is tightly connected 32 of joint 3 front ends; Put socket 5 again, at last with roll the connect portion 51 of socket 5 through its rear end with joint 3, roll and connect that cover 4, pipe box 2 are rolling to be one.
