Closestool water tank drain valve
The invention provides a closestool water tank drain valve. The closestool water tank drain valve comprises a body, an inner core pipe, a lifting device, a drainage control device and a base; the drainage control device is arranged in a cavity of the body and comprises a floating barrel, an unlocking block, a linkage rod and a limiting protrusion, the lifting device is arranged in the cavity and arranged on an installation base of the body, a pushing piece is arranged in the middle and located below an abutting piece of the linkage rod, the upper portion of the pushing piece abuts against theabutting end of the inner core pipe, and the lifting device pushes the inner core pipe to ascend to achieve drainage, when the inner core pipe ascends until the limiting protrusion exceeds the unlocking block, the inner core pipe and the linkage rod are synchronously driven to ascend, the linkage rod drives the unlocking block to move to be inserted into the lower portion of the limiting protrusion, and the limiting protrusion is locked on the upper portion of the unlocking block; and after drainage is completed, the floating barrel loses buoyancy to drive the linkage rod to descend, the linkage rod drives the unlocking block to move out of the lower portion of the limiting protrusion to unlock the inner core pipe, and the inner core pipe falls off to close the drainage valve for drainage.The inner core pipe is locked without depending on buoyancy of the floating barrel, and the size of the floating barrel can be smaller.
本发明提供一种马桶水箱排水阀，包括本体、内芯管、升降装置、排水控制装置、底座；排水控制装置设在本体的空腔内，包括浮桶、解锁块、连动杆、限位凸起，升降装置置于空腔内并设在本体的安装座上，中部设有推件，推件位于连动杆的抵靠件的下方，上部抵靠内芯管的抵靠端，升降装置推动内芯管上升，实现排水阀排水，内芯管上升到限位凸起超过解锁块时，同步带动内芯管和连动杆上升，连动杆带动解锁块移动插入限位凸起的下部，将限位凸起锁在解锁块上部；排水完成后，浮桶失去浮力带动连动杆下降，连动杆带动解锁块移动退出限位凸起的下部解锁内芯管，内芯管下落关闭排水阀排水。本发明内芯管上锁不依靠浮桶的浮力，浮桶的体积可以做得更小。
