Abstract
The utility model provides a transitional joint for the connection of a steel pipeline and a plastic pipeline. The transitional joint comprises a steel pipe, a tightening sleeve and a plastic pipe, wherein a sealing groove is formed at the tail end of the steel pipe; a retaining ring and a rubber seal O-shaped ring are mounted on the sealing groove; and the sealing groove is formed through a once-and-for-all injection molding to the steel pipe as the inlay. By adopting the technical scheme, the transitional joint for the connection of the steel pipeline and the plastic pipeline has the advantages that the sealing performance is good, the connection is convenient, and the outleakage is not liable to happen at connection parts, so as to ensure the safe operation of the pipelines greatly.
Description
Technical field
The utility model relates to a kind of joint, relates in particular to the transit joint that is connected that is used for steel pipeline and plastic pipe.
Background technique
In the prior art, all can use transit joint in tubing and often being connected of pipe fitting, its operating method is that the pipe fitting with certain-length inserts two joint pipe fitting inner walls and adopts lock ring with the joint area banding then, this mode can solve the joint problem of tubing and pipe fitting when the two pipe fittings material is identical, but, it does not connect sealing and just goes down greatly the two pipe fittings material that needs joint when chance simultaneously, can not reach good connection effect.
The model utility content
The purpose of this utility model provides the transit joint that is connected that is used for steel pipeline and plastic pipe, and its sealing height is easy to connect, efficiently solves the leakage problem of steel pipe and plastic tube attachment portion, and operation has given very big guarantee to pipe safety.
In order to reach described effect, the utility model is used for the transit joint that is connected of steel pipeline and plastic pipe, comprises steel pipe, lock ring cover and plastic tube.
Described steel pipe end is provided with seal groove, and back-up ring and rubber seal O type circle are housed on seal groove.
Described seal groove is to be that inlay is through disposable injection molded with the steel pipe.
Owing to adopted described technological scheme, what be used for steel pipeline and plastic pipe is connected the transit joint good seal performance, and easy to connect, connection part is difficult for producing leakage.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is used for the agent structure schematic representation that is connected transit joint of steel pipeline and plastic pipe for the utility model.
Fig. 2 is used for the explosive view that is connected transit joint of steel pipeline and plastic pipe for the utility model.
Embodiment
The utility model as shown in Figure 1 and Figure 2 is used for the transit joint that is connected of steel pipeline and plastic pipe, comprises steel pipe (1), lock ring cover (4) and plastic tube (5).
Described steel pipe (1) end is provided with seal groove (6), and back-up ring (2) and rubber seal O type circle (3) are housed on seal groove (6).Back-up ring (2) can limit pack into the length of lock ring cover (4) of seal groove (6), and rubber seal O type circle (3) can play good sealing effect.
Described seal groove (6) is to be that inlay is through disposable injection molded with the steel pipe.Steel pipe and seal groove form an integral body like this, make that connection is tightr, can not produce the slit.
During assembling, with pack into an end of lock ring cover (4) of plastic tube (5), the other end of lock ring cover (4) is enclosed within on the steel pipe (1), adopts hydraulic pressure technology that its banding is got final product then.
The beneficial effects of the utility model: be used for steel pipeline and the connection transit joint of plastic pipe and solved because of connecting the leakage problem of different steel pipes of material and plastic tube attachment portion, and its good seal performance, easy to connect.
The above only is a specific embodiment of the utility model, but structure characteristic of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and variation of being done or modification all are encompassed among the claim of the present utility model.
Claims (2)
