Labor-saving flap cover type drain valve
The invention discloses a labor-saving flap cover type drain valve. The valve comprises a base which is provided with a water outlet, a flapper which can be connected to the water outlet in a sealingand covering mode, a starting piece which is connected with the flapper, and a connecting rod, wherein the two ends of the connecting rod are rotationally connected with the base and the flapper respectively. When the flapper hermetically covers the water outlet, the starting piece is driven to drive the flapper to rotate relative to the connecting rod, and meanwhile, the starting piece can drivethe flapper to rotate around a first rotating fulcrum formed at the contact position of the flapper and the base so as to preliminarily open the water outlet; after the water outlet is opened preliminarily, the starting piece can drive the flapper and the connecting rod to rotate around a second rotating fulcrum formed at the rotating joint of the connecting rod and the base to further open the water outlet. Compared with an existing flap cover type drainage valve, the flap cover type drain valve ingeniously adopts a segmented drainage mode, and on the premise that it can be guaranteed that the drainage opening can be fully opened to conduct normal drainage, the tension value needed for lifting and pulling the flap cover is improved.
本发明公开了一种省力的拍盖式排水阀，包括开设有排水口的底座、能密封盖接在排水口上的拍盖、与拍盖连接的启动件以及两端分别与底座和拍盖转动连接的连杆，拍盖密封盖接在排水口上时，驱动启动件，启动件能带动拍盖相对连杆转动，并能同时带动拍盖绕拍盖与底座相接触的位置处所形成的第一转动支点转动以初步打开排水口；排水口初步打开后，启动件能带动拍盖和连杆一起绕连杆与底座的转动连接处形成的第二转动支点转动以进一步打开排水口。相比现有拍盖式排水阀，本发明巧妙地采用分段排水的方式，能够保证排水口能被充分打开以进行正常排水的前提下，实现改善提拉拍盖所需的拉力值。
