Coil switching valve
The invention provides a coil switching valve which comprises a water inlet, a water outlet A, a water outlet B, a coil assembly, an iron core, a piston switching assembly and a switching cavity communicated with the water inlet, and the piston switching assembly is arranged in a center cavity of the coil assembly and comprises a piston body, an auxiliary piston and an elastic piece. The piston body is movably connected with the auxiliary piston, an elastic piece is arranged between the piston body and the auxiliary piston, a valve seat A is arranged between the water outlet A and the switching cavity, a valve seat B is arranged between the water outlet B and the switching cavity, and a piston cap is arranged at the end of the auxiliary piston, extends into the switching cavity and is used for blocking the valve seat A or the valve seat B. The valve body is used for a water tank and pump closestool flushing system, water path switching can be achieved within several milliseconds, the problem that flushing water pressure is insufficient is solved, sealing is reliable after water path switching, water mixing between the brush ring side and the bottom flushing side is avoided, and the functions of blocking siphon generated in the flushing process and reducing flushing cavitation sound are achieved.
本发明提出了一种线圈切换阀，包括进水口、出水口A、出水口B、线圈组件、铁芯、活塞切换组件，以及与所述进水口相连通的切换腔，所述活塞切换组件设置于线圈组件的中心腔内，包括活塞主体、辅助活塞和弹性件，所述活塞主体与辅助活塞活动连接，两者之间设有弹性件，所述出水口A与切换腔之间设有阀座A，所述出水口B与切换腔之间设有阀座B，所述辅助活塞的端部设有活塞帽，所述活塞帽伸入切换腔中，用于封堵阀座A或阀座B。该阀体用于水箱加泵马桶冲洗系统，可在几毫秒内实现水路切换，避免了冲洗水压不足的问题，并且切换水路后密封可靠，刷圈侧与底冲侧不会相互串水，且有阻断冲洗过程中产生虹吸以及减小冲洗空泡音的功能。
