Switching valve capable of reducing toilet flushing noise
The switching valve comprises a water inlet, a first water outlet, a second water outlet and a switching device, a switching cavity communicated with the first water outlet and the second water outlet is formed in the switching device, a water inlet cavity is formed between the water inlet and the switching cavity, and a water outlet cavity is formed in the switching cavity. A water inlet is formed in the water inlet cavity, a ventilation cutoff device is installed between the water inlet and the water inlet cavity, a ventilation opening is formed in the ventilation cutoff device, a valve seat A is arranged between the ventilation opening and the water inlet, a valve seat B is arranged between the water inlet cavity and the water inlet, and a movable valve element is installed in the ventilation cutoff device and used for blocking the valve seat A or the valve seat B. When the water pump stops rotating and flushing is finished, the movable valve element descends to seal the valve seat B, air is prevented from entering the valve seat B from the water inlet cavity, and the problem of abnormal noise such as cavitation bubbles during flushing again is solved.
本发明提出了一种可减小马桶冲洗噪音的切换阀，包括进水口、第一出水口、第二出水口和切换装置，所述切换装置内具有与第一出水口、第二出水口相连通的切换腔，所述进水口与切换腔之间设有进水腔，所述进水口与进水腔之间安装有透气断流器，所述透气断流器上具有透气口，所述透气口与进水口之间设有阀座A，所述进水腔与进水口之间设有阀座B，所述透气断流器内安装有活动阀芯，用于封堵所述阀座A或所述阀座B。当水泵停转冲洗结束时，活动阀芯下降对阀座B进行密封，阻止空气从进水腔进入，避免了再次冲水时出现空泡等异响噪音的问题。
