Q:

How does a propane regulator work?

A:

Propane systems use pressure regulators to adjust the pressure of the propane from the tank to the appliance to prevent damage and accidents when using the appliance. These regulators are complex valves that automatically adjust the pressure of the propane gas down to a safe level for the appliance to use. Propane regulators are fitted in most standard propane gas systems, due to how important they are for the system.

Pressure regulators are used in any system where pressure is a concern, including systems that transport water or gases other than propane. Pressure regulators come in many sizes and designs that have changed over the years, but they all serve the same purpose.

The design of a pressure valve is a constant, consisting of three key component: a restricting element, a loading element and a measuring element. The restricting element involves a valve of some kind, which changes significantly according to what the regulator is designed for. The loading element applies pressure to the valve, which can be done via spring, piston or diaphragm actuator. The measuring element makes sure that the pressure from the inlet and outlet are both equal. A regulator can have a single stage or multiple stages of function, and these components are arranged differently depending on the amount of stages or purpose of the regulator.

    How does a radiator overflow tank work?

    A:

    A radiator overflow tank collects the expanding coolant that is heated by the engine and recycles it back into the coolant system once it loses enough heat. The radiator overflow tank works in conjunction with the radiator cap to protect the engine and prevent coolant loss due to overflow, according to HowStuffWorks.

    How does an oil tank measuring stick work?

    A:

    A vehicle's dipstick is located in a pipe that runs deep into the engine to allow a person to accurately measure the level of oil. By cleaning it off and reinserting it into the pipe, it is then possible to pull it out to see whether the engine has enough oil.

    How does a water well pressure tank work?

    A:

    According to Flotec, a manufacturer of water well and water pumping equipment, the water well pressure tank is a storage tank that prevents the well pump from turning on and shutting off repeatedly by using air pressure to maintain water pressure to home fixtures. As water fills the tank, the air inside is compressed, providing needed pressure to cause water to flow through pipes when a tap is opened.
