To achieve these goals, the technical solution adopted in the utility model is such: sewer SEALING FITTING of the present utility model, comprise pipe joint, pipe joint top and bottom are connected to upper limit ring and lower limit ring, upper limit ring and lower limit ring are all sealedly connected on pipe joint, in upper limit ring, convex type ring is installed, convex type ring upper surface and upper limit ring are tightly connected, its lower surface is connected with a U-tube body, U-tube body top and upper limit ring are tightly connected, upper limit ring is each passed through and pipe joint is communicated with pipe joint bottom opening place bottom it, U-tube body one side is provided with catch, catch is fixed on U-tube body, infiltration pad is connected with between pipe joint and lower limit ring, upper limit ring, pipe joint and lower limit ring outer side surface are all vertically provided with protection apron, the curved structure of protection apron, protection apron is all coated on upper limit ring, on pipe joint and lower limit ring.
Further, as a kind of concrete structural type, upper limit ring described in the utility model and lower limit ring are all threaded with between pipe joint.
Further, as a kind of concrete structural type, upper limit ring described in the utility model and lower limit ring and pipe joint joint are provided with water stop spacer.
Further, as a kind of concrete structural type, upper limit ring described in the utility model is provided with the ring edge of mating with convex type ring.
Further, as a kind of concrete structural type, U-tube body described in the utility model adopts plastic tube body structure.
Further, as a kind of concrete structural type, U-shaped inboard wall of tube body described in the utility model is coated with etch resistant layer.
Further, as a kind of concrete structural type, lower limit ring described in the utility model is provided with the ring-shaped clamping sleeve identical with its surface configuration.
Compared with prior art, the utility model has the advantage of: this sewer SEALING FITTING has good spacing performance, sealing is strong, not easily occur Seepage, and can effectively stop sewage to be discharged, self structure be strong, protection effect is good, not easily be damaged, cost of production is also lower, can better be used for sealing water pipe.
