Vacuum Gate Valves
Vacuum gate valves have a huge variety of uses in modern appliances. Indeed, vacuum in general is a force that is used for a number of reasons. Beyond the obvious vacuum cleaner, vacuum is also used as a power source for a number of powerful appliances, such as car engines. Gasoline engines naturally create a source of vacuum, and this is what allows the entire brake system to work, as it amplifies the pressure that is placed on the brake pedal. Without the vacuum source, it would take a very long time to stop a car going at any high speed.
However, vacuum moves things indiscriminately, and in any appliance that’s designed to use it, there must be some way to filter out the general dirt and grime that naturally gets sucked in along with the air. Also, sometimes the pressure that vacuum creates is the purpose of the device, and not whatever the vacuum could be sucking. To go back to the car engine example, you don’t want the vacuum to be sucking any debris into the engine itself, and so you need the vacuum hose to be filtered so that the debris cannot harm the source of the vacuum.
Vacuum gate valves are a type regulatory device that can filter the supply of vacuum intermittently. They exist to control the flow of different elements that are controlled by a vacuum, whether they are gases, liquids, or even solids. In order for a vacuum gate valve to work correctly, it needs to be able to open and close an opening – this is what allows it to control the flow of objects through it. It also needs to have a vacuum hose (or any object that transmits vacuum through it) to be covered completely by the valve. Otherwise, the valve won’t cover enough space to completely control the flow of substances.
This means that a vacuum gate valve must have a few parts in order to work. The first is a body. It must have a hole that will fasten to a vacuum hose. This is what transmits the vacuum past whatever the vacuum gate valve. The second part that a gate valve must have is a gate of some sort. This functions as a lid, and it is triggered at a certain time to stop the vacuum and/or debris from getting threw the opening of the valve. The last part that a gate valve must have is a mechanism that opens and shuts the gate. This is called an actuator, and it is responsible for controlling any movement that goes on with the gate mechanism.
Vacuum gate valves were devolved in the late 1940’s, when vacuum seal technology became more advance due to similar military technology. The original sealant that was used to develop vacuum gate valves actually comes from airplane technology. Before this, vacuum devices usually had the gate and the valve operate as separate parts. There are a number of types of vacuum gate that have different functions, and are powered and operated in different ways.
Vacuum gate valves are defined by whatever feature makes them distinctive. The most important classification is the size, as this usually is what determines the type of application the vacuum gate valve is used for. Some gates slide faster than others, and some don’t slide at all, meaning that the gate doesn’t touch the rest of the valve’s body. Vacuum gate valves can be very expensive items to buy, some costing over five thousand dollars, and even the cheapest of them can cost at least $500 or so.
