Water-pressure-started drain valve
The invention provides a water-pressure-started drain valve. The water-pressure-started drain valve comprises a drain valve body, an inner core pipe, a drain floating barrel, a water-pressure starting device and a base, wherein the drain valve body comprises a mounting seat and a shell, the mounting seat is mounted on the base, and the shell is mounted on the mounting seat; the inner core pipe is arranged on the mounting seat in a sliding mode, a water sealing piece is fixed to the lower end of the inner core pipe, the drainage floating barrel is hinged into the shell through a swing arm, a limiting step is arranged on the swing arm, a limiting protrusion is arranged on the outer side wall of the inner core pipe, the water pressure starting device is arranged in the shell and comprises a piston cylinder, a piston rod and a piston, the piston barrel is arranged on the mounting seat, the lower end of the piston rod is arranged in the piston barrel and connected with the piston, the upper end of the piston rod abuts against the upper end of the inner core pipe, liquid seal is formed between the piston rod and the upper portion of the piston barrel, a reset spring is arranged, a water pressure cavity is formed between the piston and the lower portion of the piston barrel, and a water opening is formed in the bottom of the piston barrel and communicated with the water pressure cavity. The drain valve is opened according to the hydraulic piston principle, and convenience and labor saving are achieved.
本发明提供一种水压启动的排水阀，包括排水阀体、内芯管、排水浮桶、水压启动装置、底座；排水阀体包括安装座和壳体，安装座装在底座的上，壳体装在安装座上；内芯管滑动设置安装座上，内芯管的下端固定有封水片，排水浮桶通过摆臂铰接在壳体内，摆臂上设有限位台阶，内芯管的外侧壁上设有限位凸起，水压启动装置设于壳体内，包括活塞筒、活塞杆、活塞，活塞筒置于安装座上，活塞杆的下端置于活塞筒内与活塞连接，活塞杆的上端推抵内芯管的上端，活塞杆与活塞筒的上部之间形成液密封，并设有复位弹簧，活塞与活塞筒的下部之间形成水压腔，活塞筒的底部设有水口与水压腔相通。本发明通过液压活塞原理开启排水阀，轻便省力。
