The water joint 1 passes through the mounting opening 9 on the mounting seat 10, and simultaneously, the water joint 1 and the mounting seat 4 are tightly connected into a whole by adopting the fixing bolts 12 to sequentially pass through the mounting holes 3 on the water joint 1 and the mounting grooves 8 on the mounting seat 10 and then are combined with the threads on the mounting grooves 8; meanwhile, the water channel 14 is sealed by the first sealing ring 5 in the triangular groove 11 formed between the first inclined surface 7 of the top edge of the mounting opening 9 and the water joint 1 and the second sealing ring 6 between the groove 4 and the mounting seat 10, and the sealing performance of the water channel 14 is enhanced in a multiple sealing mode formed by the radial sealing mode and the triangular groove 11 sealing mode.
In one embodiment of the utility model, in order to facilitate the water joint 1 to be quickly and correctly mounted to the mounting opening 9 of the mounting seat 10, a second inclined surface 13 is arranged at the bottom edge of the water joint 1, and meanwhile, the water joint 1 descends along the gradient of the first inclined surface 7 in a matched limit manner, so that the second sealing ring 6 can be smoothly attached to the inner wall of the mounting opening 9 in the mounting seat 10 to finish sealing. Meanwhile, when the lower groove 4 of the water joint 1 is processed and radial sealing is arranged, the first inclined plane 7 arranged at the mounting opening 9 reduces the cost of the manufacturing process, and meanwhile, the triangular groove 11 can be formed with the water joint, and the first sealing ring 5 is arranged in the triangular groove.
Because the whole car can vibrate back and forth up and down in the running process, the rebound resilience and the compressibility of the material during sealing are considered. In one embodiment of the present utility model, the material of the seal ring may be various materials known to those skilled in the art, such as leather, asbestos, etc., as long as a good sealing effect can be achieved.
