Temperature Control Valves, Insuring Safety And Pressure Distribution
Temperature control valves are usually used during the transport of water and many other liquids. Control valves are used as safety features when hot water is involved to relieve excess pressure due to over pressurized pipes. Water under pressure can have a very destructive effect; as can be seen on the news during disasters such as flood waters carrying away heavy items such as cars and even homes.
Whether you live in a house or an apartment building, temperature control valves will most likely be around you to protect you and your family. An electric heater has a special valve that will allow steam to be released harmlessly if the temperature is too high inside the tank. The plumbing inside your house and building has a specific resistance to pressure, if this is exceeded, the pipes may rupture and there will be water everywhere. Valves are set in strategic points and they will open and release the water pressure if the plumbing is in danger.
Each valve has a different purpose and different settings. Some are used for water, others for steam and yet others are used for different kinds of gases which flow in pipe lines. The valves used in your electric water heater are adjustable because they work in direct relation to the temp controls, if you raise the temperature in your tank, the valves release pressure will increase too. Valves related to the flow of room temperature water work on pressure only.
Control valves are made in many different sizes and have different uses, even your coffee machine has a valve that will be released if the water is too hot or if pressure accumulates in the plumbing. Some are not used as security devices but more like a stop sign. They will hold a liquid or gas in check until it reaches a certain temperature and then it will be released to continue on with the process which it is involved in. Most of these valves are not adjustable, they are factory set to a specific temperature or pressure rate. That way they cannot be tampered with, the pressure and temperature release mechanisms are sealed inside the valve.
An example of this is the preparation of paint; some of the ingredients need to be mixed at a certain temperature, therefore the control valve on each ingredient is connected to the temp controls in each vat separately, and when the correct temperature is reached the control valves open and allow them to mix properly. This makes the process fast, easy and automatic.
Temperature control systems are all around us every day, we may not see them, but they are there. They save us a lot of time, even when we forget to turn off the water kettle on the stove, she lets out steam in a whistler to let us know that the water is hot. This, for your entertainment is an example of a very simple yet effective temperature control valve which protects the kettle from burning when the water in it has evaporated after you forgot it on the fire.
