Abstract
The utility model discloses a water pipe connector provided with a reinforced sealing structure which relates to the manufacture field of water supply facilities and includes a connecting part (3) and a water passing runner (4); the inner wall of the connecting part (3) is provided with a thread groove (1); the screw pitch of the thread groove (1) is 2-8mm; the depth of the thread groove (1) is 0.4-1.2mm; the helical angle of the thread groove (1) is 4-12 degrees; the inner diameter of the connecting part (3) is larger than the inner diameter of the water passing runner (4); and an annular sealing groove (2) is arranged at the jointing step of the connecting part (3) and the water passing runner (4). The thread groove (1) of the water pipe connector provided with the reinforced sealing structure improves the combining strength and sealing intensity of a water pipe and a water pipe connector. The thread groove (1) of the water pipe connector provided with the reinforced sealing structure improves the strength of connection and combination between the water pipe and the water pipe connector; and the sealing groove (2) leads the connection between the water pipe and the water pipe connector to e sealed better.
Description
Technical field
The utility model relates to water facilities and makes the field, especially with the water pipe adapter of reinforcement sealing structure.
Background technique
Water pipe and being connected of water pipe adapter be by heat melting device with the connection part fusion after high temperature bond form, the present water pipe and the connection part of water pipe adapter all are smooth, water pipe with rely on fusion being connected of water pipe adapter fully after the intensity of high temperature bond, if the bad situation that connects blow-by and leak that is easy to generate is installed, the colleague makes the joint of water pipe and water pipe adapter that loose or dislocation takes place easily for a long time, and causes the generation of the situation of leaking.
Summary of the invention
The utility model to technical problem to be solved is, with water pipe adapter generation is installed and is connected packing less defective in order to overcome existing water pipe, further improves the intensity that is connected combination of water pipe and water pipe adapter.The utility model provides a kind of water pipe adapter with reinforcement sealing structure, water pipe and water pipe adapter is installed be connected the leakage of sealing nothing.
The technical solution used in the present invention is: the inwall at the water pipe adapter connection part is provided with thread groove, the pitch of thread groove is 2-8mm, the groove depth of thread groove is 0.4-1.2mm, the helix angle of thread groove is 4-12 °, and helix angle is the tangent line of thread groove and the angle of the tube wall that passes through the point of contact.
The internal diameter of water pipe adapter connection part is provided with annular seal groove at the water pipe adapter connection part with the step place that is connected of the mistake water flow passage of water pipe adapter greater than the internal diameter of the mistake water flow passage of water pipe adapter, and excellent employing right-angled triangle is selected in the cross section of sealed groove.
The beneficial effects of the utility model are: in use, pipe outer wall after the heat melting device fusion is easy to embed thread groove and sealed groove, thread groove has improved water pipe and has been connected the intensity of combination and the intensity of sealing with water pipe adapter, sealed groove makes water pipe be connected better sealing with water pipe adapter, has improved working efficiency.The utility model simplicity of design is easy to processing.
