摘要： A plunger-type diaphragm valve is disposed in an accommodation trough of a flush device. The accommodation trough communicates with an inlet passage and an outlet passage. The valve includes a control unit. One end of the control unit is provided with a diaphragm member and an engaging member, and another end leans against the outlet passage to block the inlet passage and the outlet passage. An outer wall of the diaphragm member is fixed to the accommodation trough. The diaphragm member has a curved portion. When the valve is actuated, the curved portion is deformed by water pressure to bring the control unit to move away from the inlet passage for the inlet passage to communicate with the outlet passage. The stressed area of the diaphragm member is small and the deformation is less, so the diaphragm member won't wear. The valve is durable and has a long life.

摘要： A solenoid valve includes a water inlet valve seat, a guide seat, a coil barrel, and a water outlet valve seat. When in an open state, an iron core is moved to close a pressure relief hole via an iron core spring and water pressure, and the diaphragm blocks the water flow of a water inlet via water pressure and the force of a guide spring, so as to achieve a bistable effect. The coil barrel includes two pairs of magnets and a pair of magnetically conductive sheets to form two magnetic routes. The solenoid valve has a simple structure and can be produced easily.

摘要： A control valve of a manual/automatic and cold/hot water faucet includes a sliding member, a linking member, and an operating member. The sliding member has a notch. The linking member is recessed with a connecting groove. The operating member has a valve stem and a linking portion. The linking portion drives the linking portion and the sliding portion through the connecting groove. The valve stem, the connecting groove and the central axis are arranged concentrically, so that the overlapping area of the notch and the cold water hole is equal to the overlapping area of the notch and the hot water hole to keep the same ratio of cold water to hot water in an automatic mode to dispense water, thereby increasing the safety in use.

摘要： A solenoid valve includes a valve seat with a hole, a magnetically conductive hollow winding reel, an induction coil unit wound around the reel, a permanent magnet fixed on the reel, and a magnetically insulating vertical tube disposed within the reel. A moving core is biased by a spring to a lower limit position so as to close the hole, thereby preventing water flow though the hole. A magnetic fluid is filled within a sealed gap between the reel and the tube. When a forward current flows through the coil unit, the core is attracted by the magnet so as to move to an upper limit position, where the hole is open, thereby permitting the water flow through the hole. When the core is disposed at the upper limit position and when a reverse current flows through the coil unit, a magnetic repulsion force is created between the magnet and the core, thereby returning the core to the lower limit position with assistance from the spring.
摘要翻译：电磁阀包括具有孔的阀座，导磁中空卷绕卷轴，缠绕在卷轴上的感应线圈单元，固定在卷轴上的永磁体和设置在卷轴内的磁绝缘垂直管。移动的芯由弹簧偏压到下限位置，以便关闭孔，从而防止水流过孔。磁性流体填充在卷轴和管之间的密封间隙内。当正向电流流过线圈单元时，磁芯被磁体吸引，以移动到上限位置，在该上限位置，孔被打开，从而允许水流过孔。当芯设置在上限位置时，并且当反向电流流过线圈单元时，在磁体和磁芯之间产生磁力排斥力，从而在从弹簧的帮助下将磁芯返回到下限位置。
