In the present embodiment, since the upper annular groove 37 is higher than the core back hole 113, the lower annular groove 38 is lower than the core back hole 113; and the two connecting caulking grooves 39 which are communicated with the upper annular groove and the lower annular groove are respectively positioned at two sides of the water outlet hole 32 of the valve casing 3, and are respectively positioned at two sides of the core pulling hole 113, so that the upper sealing ring 54 nested in the upper annular groove 37, the lower sealing ring 55 nested in the lower annular groove 38 and the matching between the elastic ribs 56 respectively nested in the two connecting caulking grooves 39 and the outer wall of the valve casing 3 and the inner wall of the valve seat 11 can block the communication between the core pulling hole 113 of the valve seat 11 and the water inlet flow passage 121 and the communication between the core pulling hole 113 of the valve seat 11 and the water outlet flow passage 21.
In this embodiment, a positioning mechanism may be disposed between the valve housing 3 and the valve seat 11 to accurately mount the faucet cartridge B in the valve seat 11, so as to ensure the communication between the water outlet 32 and the water outlet 112 and the communication between the water inlet 31 and the water inlet 111, thereby ensuring the construction of the waterway of the present invention. As shown in fig. 21, the positioning mechanism includes a positioning protrusion 34 disposed on an outer wall of the valve housing 3 and a positioning groove 115 disposed on an inner wall of the valve seat 11 and configured to be clamped by the positioning protrusion 34, where the positioning protrusion 34 and the positioning groove 115 may be disposed in opposite directions, that is, the positioning protrusion 34 may be disposed on the inner wall of the valve seat 11 and the positioning groove 115 may be disposed on the outer wall of the valve seat 11.
The above examples and drawings are not intended to limit the form or form of the present invention, and any suitable variations or modifications thereof by those skilled in the art should be construed as not departing from the scope of the present invention.
