Closestool flushing system, pressurizing device and pressure relief structure of pressurizing device
The invention discloses a pressure relief structure of a pressurizing device, which comprises a pressure relief body and a movable part; the pressure relief body is provided with a pressure relief cavity, a pressure relief channel, an inlet channel and an outlet channel communicated with a pressurizing cavity of the pressurizing device, and the inlet channel, the outlet channel and the pressure relief channel are respectively communicated with the pressure relief cavity; the movable part is provided with a through-flow channel, fluid in the inlet channel flows to the outlet channel through the through-flow channel, and the through-flow sectional area of the through-flow channel is smaller than that of the inlet channel; after the pressure source inputs pressure fluid into the inlet channel, the movable part moves towards one side of the outlet channel to a second position under the action of the pressure difference between the two sides of the movable part so as to close the pressure relief channel; after the pressure source stops inputting the pressure fluid into the inlet channel, the movable part moves to the first position towards one side of the inlet channel under the action of reset force so as to open the pressure relief channel. The pressure relief structure is simple, reliable in function and low in cost. The invention further discloses a pressurizing device with the pressure relief structure and a closestool flushing system.
本发明公开了一种加压装置的泄压结构，包括：泄压本体，具有泄压腔、泄压通道、进口通道、与加压装置的加压腔相连通的出口通道，进口通道、出口通道和泄压通道分别与泄压腔相连通；活动件，具有通流道，进口通道的流体经由通流道流至出口通道，通流道的通流截面积小于进口通道的通流截面积；压力源对进口通道输入压力流体后，活动件在活动件两侧的压力差作用下往出口通道一侧的方向活动至第二位置以关闭泄压通道；压力源停止对进口通道输入压力流体后，活动件在复位力的作用下往进口通道一侧的方向活动至第一位置以打开泄压通道。本发明的泄压结构简单、功能可靠、成本低。本发明还公开了一种具有泄压结构的加压装置和马桶冲洗系统。
