Abstract
The utility model discloses a sealing joint, it mainly comprises connector (1) and cap, connector (1) is the internal screw thread pipe fitting that has of cyclic annular arch (2), and the pipe fitting has the external screw thread in one side of cyclic annular arch (2), and the pipe fitting part of outband screw thread has a pair of parallel surface (3) at least, and this external screw thread is connected with the interior screw-thread fit of cap, and cyclic annular arch (2) are equipped with the recess on facing the face of external screw thread, are equipped with sealing washer (4) in the recess. By adopting the structure, the connector (1) and the end cover of the box body are firmly connected, so that the phenomenon of rotation can not occur when the pipeline is maintained and replaced, and the sealing performance is good.
Description
Technical field
The utility model relates to the SEALING FITTING of drawing fluid path in a kind of fluid box, especially for the SEALING FITTING of water heater internal water tank ventilating water pipe.
Background technique
The present water pipe channel on the water heater internal water tank end cap generally adopts inside and outside two and cap to clamp end cap, and two and cap are tightened in water and chew, and this structure is when the maintain and replace pipeline, and water is chewed to rotate with pipeline and unclamped, and leaks thereby make between end cap and the connecting head.
Summary of the invention
The utility model provides a kind of SEALING FITTING, is connected firmly between it and the housing plate, when the maintain and replace pipeline, and then rotation phenomenon can not take place, good seal performance.
The utility model adopts following technological scheme to realize: a kind of SEALING FITTING, it mainly by connecting head and and cap form, connecting head is the female pipe fitting of band shape projection, pipe fitting has outside thread in a side of annular projection, this outside thread with and the screw-internal thread fit of cap be connected, annular projection is provided with groove on facing to externally threaded, be provided with seal ring in the groove.
Describedly be with externally threaded pipe fitting partly to have the pair of parallel face at least.
Face described and that cap is relative with connecting head is provided with groove, is provided with seal ring in the groove; Perhaps also the cap face relative with connecting head is provided with sealing gasket.
The utility model adopts said structure, and annular projection is provided with seal ring, accompanies seal ring between water tank interior edge face and the annular projection like this, good seal performance.The internal thread length of connecting head is longer, installs when water is chewed to be connected firmly.Have on the water tank end cap and the through hole that matches with the male element shape, because the band male element has parallel surface, this pipe fitting is not easy to take place the and then phenomenon of rotation when changing pipeline like this, thereby the leakage of water can not occur.
