Backflow prevention assembly of drain valve
A drainage assembly comprises a sleeve and a water stop assembly which are connected with each other, the sleeve is provided with an elastic limiting device capable of sliding in the radial direction, a counterweight assembly capable of sliding in the axial direction is arranged in the sleeve, and the counterweight assembly is provided with a groove used for being connected with the elastic limiting device in a clamping mode. Under the non-drainage working condition, one end of the elastic limiting device abuts against the lower end face of the bottom plate, so that the water stop assembly cannot move upwards at the position where the drainage opening is closed, the drainage assembly cannot be opened even if sewage below the drainage opening flows upwards and applies upward thrust to the drainage assembly, and the backflow prevention effect is achieved; under the drainage working condition, the other end of the elastic limiting device is inserted into the groove in the process of driving the counterweight assembly to move upwards, so that one end of the elastic limiting device is separated from the bottom plate, and the sleeve drives the water stop assembly to open the drainage port. The elastic limiting device is integrated on the drainage assembly, other parts of the drainage valve do not need to be changed, and the product optimization cost is low.
一种排水阀防倒流组件，其排水组件包括相互连接的套筒和止水组件，套筒设有可径向滑动的弹性限位装置，套筒内设有可轴向滑动的配重组件，配重组件设有用于卡接弹性限位装置的凹槽；未排水工况，弹性限位装置的一端抵接于底板下端面，使得止水组件在关闭排水口的位置无法上移，即使排水口下方的污水向上回流对排水组件施加向上的推力也无法打开排水组件，从而形成防倒流作用；排水工况，驱动配重组件上移过程中使得弹性限位装置的另一端插入凹槽使得弹性限位装置的一端脱离底板，并通过套筒带动止水组件打开排水口。该弹性限位装置集成在排水组件上，无需改变排水阀其他零部件，产品优化成本低。
