Cylinder valves, also called a rotary gate, are devices that directs, regulate or control the flow of gas, liquid, or loose masses, and does this through piping or apertures. Due to its usually simple design, and huge range of applications, it has been used in vast arrays of works, from home use to heavy duty manufacturing industries. Valves have proven to be one of the very important inventions of this world.
The origins of this gate device can be traced from ancient times where stones, trunks of trees or branches were used to regulate the flow of water. The Romans then constructed aqueducts and canals that delivered water from its source into cities, which needed to be stopped whenever needed. The first fluid gates were then made in a form of plugs and stopcock types.
During the Middle Ages, minute developments were contributed to its design. Sophisticated designs were found only when during the Renaissance and were being used for hydraulic works, canals and irrigation. Further breakthroughs were made during the Industrial Revolution where they were designed to cope with the pressures of steam trains, and still have the option for minor adjustments.
Many changes and different version are now available, thanks to innovators who found ways in deviating the original design in order to get a different way to control fluids. Main differences on the types of gates would be dependent on the flow rate regulation, pressure to be handled, protection versus over pressure or over speed of flux, back flow prevention and the original on and off option.
Three general types of gates are currently available in the market, with the multi-turn valve being the most common of them all. A handle is attached on a threaded screw and is placed outside of the membrane, while a rubber seal is placed on the other end that would be located inside of the membrane. The rubber seal is the one that would either allow or not the flow of fluids, while the turning movement using the handle would determine on which setting it would be in. This process is slower but has greater accuracy and stability in terms of regulating the speed of flow.
The quarter-turn gate, which are also called butterfly valves, are the type of valve where the handle and the stopping member inside the membrane is directly attached to each other. The angle required to either full close or open the gate is only up to ninety degrees. That would mean that this gap is the one that would determine the speed of flow and is usually less accurate than the first type, but easier to use.
The remaining type of gate is called a check or one-way valve, is a fully automated gate that was made to ensure that there is only one direction of flow inside the cylinder. The main concept of this was the closing member inside the membrane that is pushed open when the path of the flux is correct, and is pushed close when the flux goes the other way.
With all of the improvements and developments involved in cylinder valves, this has been made into a device so versatile that our own home probably has lots of them. It may always be safe to assume also that even the simplest things we use daily has a very rich history and makes us fully appreciate how our lives are today, compared to those who had lesser tools in the olden days.
