The invention relates to an anti-siphon backflow flushing valve. The anti-siphon backflow flushing valve comprises a water inlet valve body, an upper flushing valve body and a lower flushing valve body. A water inlet cavity is formed in the water inlet valve body, and an upper flushing cavity and a lower flushing cavity which are communicated with the water inlet cavity are formed in the upper flushing valve body and the lower flushing valve body respectively; electromagnetic valves are arranged on the upper flushing valve body and the lower flushing valve body; a communication pipe is arranged between the upper flushing valve body and the lower flushing valve body, and the communication pipe is communicated with the upper flushing cavity and the lower flushing cavity, so that an upper flushing opening and a lower flushing opening of a closestool are communicated to form a normally-open flow channel, the pressure relief and emptying effects are achieved, and accumulated water in the upper flushing pipe and the lower flushing pipe can be directly discharged downwards into a sewage pool through the lower flushing opening. When the closestool is in a static state and is installed at a high floor, and water supply of the water supply pipe network is cut off, the water supply pipe network can only suck air from the upper flushing opening through the communication pipe, accumulated water or dirt in a water storage pool cannot be sucked back, and the possibility that a public water supply pipe network system is polluted during siphon backflow is eradicated fundamentally.
本申请涉及一种防虹吸回流冲水阀，包括进水阀体、上冲阀体与下冲阀体；所述进水阀体内设置有进水腔，上冲阀体与下冲阀体内分别设置有与进水腔连通的上冲水腔与下冲水腔；所述上冲阀体与下冲阀体上均设置有电磁阀；所述上冲阀体与下冲阀体之间设置有导通管，导通管连通上冲水腔与下冲水腔，使马桶的上冲水口与下冲水口之间连通形成一个常开的流道，起到泄压排空的效果，使上冲、下冲水管内的积水能够直接通过下冲口向下排入污水池中。当马桶处于静止状态且安装在楼层高位而供水管网停水时，供水管网只会通过导通管从上冲水口处抽吸空气，而不会将存水池内的积水或污物反吸上来，从根源上杜绝了虹吸回流时污染公共供水管网系统的可能。
