When the handle of a flush toilet with a tank (British, cistern) is turned, a discharge mechanism is activated by means of a rod or chain. The mechanism may be a flapper valve, which is designed to sink more slowly than the water - allowing the water to exit to the toilet bowl below, so that the tank may empty.
Your toilet is always there for you. If you haven’t, you could be in for some heartbreak when things start to go wrong: running water, a flush handle that doesn’t work, even “ghost” flushes.
Thomas Crapper did not invent the flush toilet. [415] A forerunner of the modern toilet was invented by the Elizabethan courtier Sir John Harington in the 16th century, [416] and in 1775 the Scottish mechanic Alexander Cumming developed and patented a design for a toilet with an S-trap and flushing mechanism. [417]
In plumbing, a trap is a U-shaped portion of pipe designed to trap liquid or gas to prevent unwanted flow; most notably sewer gases from entering buildings while allowing waste materials to pass through. In oil refineries, traps are used to prevent hydrocarbons and other dangerous gases and chemical fumes from escaping through drains.
The nozzle and flapper mechanism is a displacement type detector which converts mechanical movement into a pressure signal by covering the opening of a nozzle with a flat plate called the flapper. [1] This restricts fluid flow through the nozzle and generates a pressure signal.
When hydraulic pressure is applied down a control line, the hydraulic pressure forces a sleeve within the valve to slide downwards. This movement compresses a large spring and pushes the flapper downwards to open the valve. When hydraulic pressure is removed, the spring pushes the sleeve back up and causes the flapper to shut.
Although it is likely that flatulence humor has long been considered funny in cultures that consider the public passing of gas impolite, such jokes are rarely recorded. It has been suggested that one of the oldest recorded jokes was a flatulence joke from the Sumerians that has been dated to 1,900 BC. [1]
A flush toilet (also known as a flushing toilet, water closet (WC); see also toilet names) is a toilet that disposes of human waste (i.e., urine and feces) by collecting it in a bowl and then using the force of water to channel it ("flush" it) through a drainpipe to another location for treatment, either nearby or at a communal facility.
