一种用于控制太阳能热水器进、出水流的直动式节能电磁永磁水阀，最近在大连市研制成功，并已向国家申报了专利。该水阔用电量低微，通电0．5秒即可实现开、关动作，一旦动作后不再消耗电能。由于其动作后靠永磁铁自锁，故处于自锁状态时线圈设有电压，不存在漏电等不安全因素 A direct-acting energy-saving electromagnetic permanent magnet water valve used to control the inflow and outflow of solar water heaters has recently been successfully developed in Dalian and has been declared a patent by the state. The wide water consumption is low, power 0.5 seconds to achieve open, off action, once the action is no longer consume power. Because of its action by the permanent magnet self-locking, so in the self-locking state when the coil voltage, there is no leakage and other unsafe factors
