<p>A water-saving valve includes a base (10), a control valve assembly (20) and a buffer assembly (30). The base (10) has a containing hole (111), the control valve assembly (20) is arranged in the containing hole (111) and has a valve rod (24). The buffer assembly (30) is arranged on the control valve assembly (20) and composed of a bearing seat (31), a sleeve element (32) and a water inlet seat (33). The bearing seat (31) is provided with a through water opening (311) which can be closed by the valve rod (24), and a projecting portion (312) is projected on the top surface of the bearing seat (31). The sleeve element (32) is a circular-disk body whose center is projected upward, and it is arranged on the bearing seat (31) and provided with a through sleeve hole (321). The sleeve hole (321) is sleeved on the projecting portion (312) of the bearing seat (31), and its pore diameter is slightly greater than the radial width of the projecting portion (312). The water inlet seat (33) is arranged on the sleeve element (32) and provided with a through water inlet (331), and a groove (332) is formed at the center of the bottom surface of the water inlet seat (33), and a through flowing channel (334) communicated with the groove (332) is arranged in a sidewall of the water inlet seat (33). The water-saving valve can reduce the pressure in the water tube, thus avoiding noise or damage to the water tube.</p> |
