Introduction And Working Principle Of Wash Down Closet

The wash-down closet is a toilet that uses the gravity of water to convert the potential energy of the water into kinetic energy of water, so as to carry the excrement and dirt into the toilet. , water supply organs, water tanks, urinals, and other components.

working principle

Here's how a wash-down closet bowl works:

Use the water discharge knob and water plug to control water discharge and water storage. When in use, rotate the water discharge knob, and use the metal rope or nylon rope connected to the water plug to pull up the water plug. The urinal uses the gravity of the water and the kinetic energy converted from potential energy to flush the excrement and dirt into the sewer pipe. At the same time, when the water level drops to a certain water level, the negative pressure generated by the gravity of the water will re-press the water plug into the outlet pipe. At this time, the water will no longer be released and a new water storage stage will begin; at the same time as the water level drops to flush the urinal, the floating ball and the lever will drive the lever to open the water replenishment mechanism due to the water level drop due to the gravity of the floating ball. Water replenishment; in the replenishment stage, the buoyancy and lever of the float ball are used to control the replenishment of the water tank. When the float ball drops to the lowest position, the water plug is just negatively pressured into the outlet of the water pipe, and the water tank begins to store water; the water inlet pipe is connected to the water pipe, which is responsible for the water source. Input, when the water replenishment reaches a certain height, the buoyancy of the water will push up the floating ball and the linkage lever will close the water supply mechanism to stop the water replenishment.

When the water inlet pipe leaks due to failure (for example the water inlet plug cannot block the water inlet or the water inlet pipe is broken), the water level in the water tank will continue to rise and eventually overflow the water tank. The setting of the seepage pipe solves this problem. When the water level rises to the mouth of the seepage pipe, the water will flow from the seepage pipe into the toilet without flooding the water tank. When the water inlet pipe is working normally, the water surface in the water tank will not reach the mouth of the seepage pipe, so there is no need to worry about the water flowing away.
