Flushometer
A flushometer is a metal water-diverter that uses an inline handle to flush tankless toilets or urinals. It was invented by William Elvis Sloan and is a product of the Sloan Valve Company. Function It uses water pressure from the water supply system rather than gravity from a raised tank like in previous models. A diaphragm separates a pressure chamber from the main water supply. A narrow passageway leads from the main water supply into the pressure chamber. It is the narrowness of this passage that meters the flow by slowing repressurizing of the pressure chamber after the action of a flush. The diaphragm technology allows the flush valve to open and let water into the bowl. A main cylinder valve operates up and down. A groove in this cylinder allows water from the main supply to flow through when it is in a mid position. The valve is shut off at both its top and bottom positions. A second valve, placed within the main cylinder valve, releases the water in the topmost pressu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Elvis Sloan
William Elvis Sloan I (October 1867 – June 25, 1961) invented the Flushometer flushing mechanism for toilets and urinals. It is installed in millions of commercial, institutional and industrial restrooms worldwide. Biography He was born in Liberty, Missouri, in October 1867. He was an apprentice pipe fitter in Missouri then moved to Chicago, Illinois. He married Bertha Moore (1874-?) in 1898 in Chicago, Illinois, and they had a child, Edith Marie Sloan (1913-?). In 1906, he founded Sloan Valve Company, which is now headquartered in Franklin Park, Illinois. He died on June 25, 1961, at the age of 93 in Chicago, Illinois, and was buried in Oak Park, Illinois. Legacy With the exception of a period of time in the 1940s and early 1950s, Sloan Valve has been under the leadership of W.E. Sloan’s descendants. He had a grandson, William Elvis Sloan II (1941–2001). References {{DEFAULTSORT:Sloan, William E. 1867 births 1961 deaths American inventors ...

Toilet Components
A toilet is a piece of sanitary hardware that collects human waste (urine and feces) and sometimes toilet paper, usually for disposal. Flush toilets use water, while dry or non-flush toilets do not. They can be designed for a sitting position popular in Europe and North America with a toilet seat, with additional considerations for those with disabilities, or for a squatting posture more popular in Asia, known as a squat toilet. In urban areas, flush toilets are usually connected to a sewer system; in isolated areas, to a septic tank. The waste is known as '' blackwater'' and the combined effluent, including other sources, is sewage. Dry toilets are connected to a pit, removable container, composting chamber, or other storage and treatment device, including urine diversion with a urine-diverting toilet. " Toilet" or "toilets" is also widely used for rooms containing only one or more toilets and hand-basins. Lavatory is an older word for toilet. The technolo ...

Sloan Valve Company
Sloan Valve Company is a Privately held company, privately held American company specializing in plumbing valves and fixtures. History The company was founded by William Elvis Sloan in Chicago, Chicago, Illinois in 1906 with the introduction of the Royal flushometer, a valve to release a measured amount of water to flush a urinal or toilet. Initial sales were very poor: only a single Royal model flushometer was sold in 1906, and two in 1907. Sales improved dramatically in 1908, to 150 units. Initially, potential customers were wary of adjusting to his invention. Even some plumbing fixture manufacturers wouldn't sell their products if they were furnished with Sloan's flushometers. However, the original 1906 design has proven so reliable that as of 2012, parts are still available to repair any flushometer ever made. In addition to its flush valves based on diaphragm technology, Sloan also introduced piston-type flushometers, including the Crown and the GEM 2. A special piston-ty ...

Water Pressure
Pressure (symbol: ''p'' or ''P'') is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Gauge pressure (also spelled ''gage'' pressure)The preferred spelling varies by country and even by industry. Further, both spellings are often used ''within'' a particular industry or country. Industries in British English-speaking countries typically use the "gauge" spelling. is the pressure relative to the ambient pressure. Various units are used to express pressure. Some of these derive from a unit of force divided by a unit of area; the SI unit of pressure, the pascal (Pa), for example, is one newton per square metre (N/m2); similarly, the pound-force per square inch ( psi, symbol lbf/in2) is the traditional unit of pressure in the imperial and US customary systems. Pressure may also be expressed in terms of standard atmospheric pressure; the unit atmosphere (atm) is equal to this pressure, and the torr is defined as ...

Gravity
In physics, gravity (), also known as gravitation or a gravitational interaction, is a fundamental interaction, a mutual attraction between all massive particles. On Earth, gravity takes a slightly different meaning: the observed force between objects and the Earth. This force is dominated by the combined gravitational interactions of particles but also includes effect of the Earth's rotation. Gravity gives weight to physical objects and is essential to understanding the mechanisms responsible for surface water waves and lunar tides. Gravity also has many important biological functions, helping to guide the growth of plants through the process of gravitropism and influencing the circulation of fluids in multicellular organisms. The gravitational attraction between primordial hydrogen and clumps of dark matter in the early universe caused the hydrogen gas to coalesce, eventually condensing and fusing to form stars. At larger scales this results in galaxies and clust ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
