English: In a typical leaded bell-and-spigot joint, the spigot is inserted into the bell of another pipe, yarn or oakum is compressed into the space, then hot lead was poured and also worked into the joint. Installers would typically use a set of tools, with different sized heads, to make sure both the yarn and lead were properly worked into ...
Faucet is the most common term in the US, similar in use to "tap" in British English, e.g. "water faucet" (although the term "tap" is also used in the US). Spigot is used by professionals in the trade (such as plumbers), and typically refers to an outdoor fixture.
English: Diagram of a water distribution system. Inlet water goes through a pumping station. The water is delivered to the top of a water tank. Water pressure created by gravity and delivered to water mains. Water mains are connected to fire hydrants and service lines which are pipes that connect a water main to a building.
Valves stop (or regulate) the flow of liquids or gases. They are categorized by application, such as isolation, throttling, and non-return. Isolation valves temporarily disconnect part of a piping system to allow maintenance or repair, for example. Isolation valves are typically left in either a fully open or closed position.
English: Axial flow valve in default (A) and engaged (B) positions. 1. airflow, from mouthpiece; 2. airflow, to bell; 3. valve tubing; 4. valve casing; 5. conical rotor; 6. input (a) and return (b) valve ports; 7. spindle axis of rotation. Simplified illustration based on patent diagrams.
The fill valve in a toilet water tank is a liquid level-actuated valve. When a high water level is reached, a mechanism shuts the valve which fills the tank. In some valve designs, the pressure of the flow fluid itself or pressure difference of the flow fluid between the ports automatically controls flow through the valve.
Replacing a valve stem. A valve stem is a self-contained valve that opens to admit gas to a chamber (such as air to inflate a tire), [1] and is then automatically closed and kept sealed by the pressure in the chamber, or a spring, [2] [3] or both, to prevent the gas from escaping.
The simplest and most common general type of plug valve is a 2-port valve [1] [2] with two positions: open to allow flow, and shut (closed) to stop flow. Ports are openings in the valve body through which fluid can enter or leave. The plug in this kind of valve has one passageway going through it.
