Any system that uses gaseous fuels as a source of power needs to be protected in order to keep the surroundings safe and secure. Having the necessary safety gear and devices is vital to ensuring the safety of those in the immediate vicinity of the system. If you are setting up an LPG system, make sure you get the help of a qualified technician to do it. Installing regulatory valves and components will help you control the flow of the gasses through the system and also act as preventive barriers between the appliances and the storage tanks.
Primary safety function
The primary function of any low pressure propane gas regulator is to make sure that the fuel is ready and available for use as and when a particular appliance demands it. It acts as a mediator between the fuel tank and the appliances, matching the flow of fuel to the level of demand. If the demand is low, the device reduces the flow and when the demand is high, it pushes through a higher volume of the fuel to the appliance. The device usually consists of a loading element, a measuring element, and a restricting element.
How it works
All the three elements combine together in a systematic way to ensure that the low pressure gas regulator works perfectly well. The restricting element restricts the flow of the fuel in varying degrees, as and how it is required by the appliance. The loading element is the part that applies the necessary force on the restricting element. This is usually done with the help of a spring, or weight, or a spring in combination with a diaphragm actuator. The measuring element’s function is to identify when the outlet flow is the same as the inflow. All these work together to provide optimum safety.
