The invention discloses a water supply and drainage control device. The water supply and drainage control device comprises a pressure-resistant blocking piece and a hose with fabric, wherein an inlet of the hose is connected with a water outlet channel in a sealed mode; the pressure-resistant blocking piece is arranged corresponding to an outlet of the water outlet channel and is installed in the water outlet channel or at the outlet of the water outlet channel; and when the pressure in the hose is smaller than the pressure outside the hose, at least part of the inner wall of the hose can be tightly attached to each other under the action of the difference between the pressure inside the hose and the pressure outside the hose, and static sealing is formed. According to the structure, static sealing can be formed on the hose through the difference between the pressure inside the hose and the pressure outside the hose, so that control over non-return, cut-off and the like of the water outlet channel is achieved, and the sealing and shielding effect of a product is guaranteed. Meanwhile, the structure can be directly installed at outlets of a valve, a drainage vehicle water pump, a ship ballast water pump and the like so as to achieve control over non-return, cut-off and the like of the valve and the water pump. The structure can be combined with the valve so as to effectively solve the problems that an existing valve is low in sealing performance and medium leakage is prone to occurring. In addition, the structure can be used for river channel dredging or maintenance.
本发明公开了一种给排水控制装置，包括耐压阻挡件和带织物软管，软管入口与出水通道密封连接；耐压阻挡件对应出水通道的出口设置，安装在出水通道内或出水通道的出口处；在软管内压力小于软管外压力时，软管的至少部分内壁可在软管内外压力差的作用下相互紧密贴合并形成静密封。该结构可利用软管内外压力差使软管形成静密封，从而实现出水通道止回、截止等控制，确保产品的密封屏蔽效果。同时该结构还可直接安装到阀、排水车水泵、船用压载水泵等的出口处，以实现阀、水泵的止回、截止等控制，且该结构还可与阀结合，以有效解决现有阀门密闭性能较低，容易产生介质泄露的问题，此外该结构还可用于河道清淤或维护。
