Abstract
The utility model discloses a connection sealing structure of a steel plastic composite pipe. The connection sealing structure comprises a spigot and faucet pipe and a spigot and faucet sleeve fixedly connected to the spigot and faucet pipe. An insertion pipe is inserted into the spigot and faucet sleeve. A sealing ring inlaid on the inner wall of the spigot and faucet sleeve is arranged between the insertion pipe and the inner wall of the spigot and faucet sleeve. A circular groove is formed in the inner end face of the sealing ring. The connection sealing structure is simple and convenient to use, simple in structure, and good in pressure resisting capacity and sealing effect.
Description
Technical field
The utility model relates to a kind of connection sealing configuration of steel-plastic composite pipe.
Background technique
Steel-plastic composite pipe, because its intensity high corrosion resistance is strong, and is widely used.At present, known connection sealing configuration is on bell-and-spigot pipe, to be connected with socket joint cover, in socket joint cover, be fitted with Inserting Tube, between Inserting Tube and socket joint cover inwall, be provided with the seal ring being installed on socket joint cover inwall, after Inserting Tube inserts in socket joint cover through seal ring, Inserting Tube and socket joint cover inwall push and make it to occur resiliently deformable seal ring, thereby realize the sealing between Inserting Tube and socket joint cover, because seal ring is solid seal ring, its elastic deformability of long duration declines, thereby causes pipe-line system voltage endurance capability to reduce.
Summary of the invention
The technical problems to be solved in the utility model is for above-mentioned defect, provides that a kind of pipe-line system voltage endurance capability is strong, the connection sealing configuration of good sealing effect.
In order to solve the problems of the technologies described above, the connection sealing configuration of the steel-plastic composite pipe that the utility model provides, comprise bell-and-spigot pipe, be fixed in the socket joint cover on bell-and-spigot pipe, in socket joint cover, be fitted with Inserting Tube, between Inserting Tube and socket joint cover inwall, be provided with the seal ring being installed on socket joint cover inwall, its structural feature is that the interior edge face of described seal ring is provided with annular groove.
The degree of depth of described annular groove is greater than 1/3rd of seal ring axial height.
In the orthographic drawing in described annular groove longitudinal section, each cell wall forms with the axial consistent straightway of seal ring with trend by the tilting section that is positioned at notch place, thereby makes annular groove become not wide annular groove wide outside and narrow inside.
The utility model on the basis of existing technology, has only been done technological improvement to seal ring, thereby has advantages of simple in structure.The setting of annular groove on seal ring, its objective is in order to make full use of the pressure of pipeline inner fluid, be after fluid enters in annular groove, fluid can be pressed on the seal ring part in annular groove outside on socket joint cover internal face, the seal ring part of annular groove inner side can be pressed in the outer wall of Inserting Tube by fluid tight, and the interior pressure of fluid is larger, and the adhesive force of seal ring and Inserting Tube and socket joint cover is larger, thereby it is strong to make the utlity model has voltage endurance capability, the advantage of good sealing effect.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
Embodiment
With reference to Fig. 1, the connection sealing configuration of steel-plastic composite pipe provided by the utility model comprises bell-and-spigot pipe 1, on bell-and-spigot pipe 1, be connected with socket joint cover 2, in socket joint cover 2, be fitted with Inserting Tube 3, Inserting Tube 3 and socket joint overlap to be provided with between 2 inwalls and are installed in socket joint and overlap the seal ring 4 on 2 inwalls, and the interior edge face of described seal ring 4 is provided with annular groove 5.The degree of depth of described annular groove 5 is greater than 1/3rd of seal ring 4 axial heights.In the orthographic drawing in described annular groove 5 longitudinal sections, each cell wall forms with the axial consistent straightway of seal ring 4 with trend by the tilting section that is positioned at notch place, thereby make annular groove become not wide annular groove wide outside and narrow inside, the slot-open-section that implication wide outside and narrow inside is annular groove is wide compared with other parts.An object of/3rd that annular groove 5 is set to not wide annular groove and makes the degree of depth of annular groove be greater than seal ring 4 axial heights is in order to make seal ring 4 more easily produce resiliently deformable under the pressure of fluid, thereby obtains better sealing and withstand voltage effect.
