Rotary gates, or know commonly called as cylinder valves, are devices where liquid, gas or loose masses are regulated, controlled or directed in as series of piping or apertures. With the vast arrays of applications and its very simple design, these devices have been used in home utilities or heavy manufacturing industries. It has proven to be a very important invention that has helped us making life easier.
The beginnings of a valve can be traced back in ancient times where water flow was regulated by the use of stones, branches or trunks of trees. When Romans developed aqueducts and canals, water was delivered from the source into the cities, and had to be stopped often. The fluid gates that were used to restrict the flux of fluid were either plugs or 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.
Innovators have continuously made ways to use the original concept and make many other different versions that controlled fluids in different ways. Main differences between each type of gate would depend on the pressure to be handled, flow rate regulation, back flow prevention, protection versus over pressure or over speed of flux 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 second type is the quarter-turn gate, also called butterfly valves, where the handle and the stopping member is attached directly to each other. The required angle to fully close or open this member is only up to ninety degrees. This makes it much more easier to use in instances where constant change is applied from time to time, but lacks the accuracy that the first type had.
The one-way or check valve is a fully automated device that was designed to ensure that the the materials inside the cylinder goes to one direction only. It does this by using a closing member that is pushed open if the flow is on the right direction, and is only pushed to close the gate 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.
