Possibilities exist that you already know this. But there is no damage in refreshing the memory. A valve is a device that regulates, controls, or guides the flow of a fluid by opening, closing, or partially blocking fluid flow. A sound little bit complicated? Ok, let me further simplify this. A valve is a mechanical device that controls the flow and pressure of fluid within a system or process. So basically, it controls flow & pressure.
Numerous sorts of pipe installations are available in plumbing systems for different objectives and features. A pipe fitting is used in plumbing system to join multiple pipes of same size or different sizes, to regulate the flow or to measure the flow. They are comprised of different materials like copper, iron, brass, PVC etc.
Reducer is a pipe fitting component which reduces the flow size from larger to smaller by reducing size of pipe. Normally there are two types of reducers are available. One is concentric reducer which is like cone formed with gradual decreasing around the pipe but in this case accumulation of air might possible and it results in cavitation. Other one is eccentric reducer which is having one side alongside attaching pipe as a result of which air accumulation is not possible.
Tee type fitting belongs of plumbing system which remains in T-shape. It is having one inlet and two outlets, outlets are arranged at 90o to the main line connection (inlet). 1bs.ir can also be used to incorporate the flow from two inlets to one electrical outlet. They are also available in different materials and different sizes. If the 3 sides of T-fitting are similar in size then it is called as Equal tee otherwise it is called as Unequal tee.
A Globe valve is used to stop, start, and regulate the fluid flow. Globe Valves are used in systems where flow control is needed, and leak tightness is also essential. A Globe valve provides better shut-off than eviction valve and is costlier than a gate valve. The check valve prevents backflow in the piping system. The pressure of the fluid travelling through a pipe opens the valve, while any reversal of flow will close the valve.
A gate valve is the most common type of valve in any process plant. It is a linear movement valve used to start or stop fluid flow. In service, these valves are either fully open or fully closed. Gate valves are used in nearly all fluid services such as air, fuel gas, feedwater, vapor, lube oil, hydrocarbon, and almost any services. The gate valve provides a good shutoff.
A coupling is used to connect the pipes of same diameter. Coupling are also beneficial if the pipe is damaged or leakage occurs. Generally there are two kinds of couplings are available. Compression coupling and slip coupling. Compression coupling is regular coupling which is connected in between two pipes and it prevents leakage by the arrangement of gaskets or rubber seals on both sides, otherwise glue is supplied. Slip coupling is easier to install and it contains two pipes which are arranged as one right into other, inner pipe can move as much as some length. So, we can fix lengthy length damaged pipe by slip coupling.
