As people become familiar with gas cylinder regulators since they are commonly seen in almost all places, there is a tendency to take them for granted. Well, in fact, only few of us even know its basic elements. These are specifically about its restricting, as well as loading and the measuring elements. These are the essential aspects that primarily define the function and purpose of this product. Most often than not, we only put our attention into its basic details once a problem occurs to our regulator. This is the reason why knowing the following elements would be crucial here.
Firstly, regulation is synonymous to restriction. This is because when you are regulating something, it means that you are restricting it from free-flowing uncontrollably. Specifically for LPG gas regulators, the restricting element is usually in the form of valve. This valve may be in different types or forms. Nevertheless, they all function just the same, which is to restrict the flow of the gas. In layman’s term, it forms a certain bottleneck that allows for the conversion of the flow from high to low pressure system. With this, the velocity of the gas should be greater in the restriction to maintain its flow.
Secondly, another element of gas bottle regulators that you need to understand is the loading. Most of the modern forms and designs of gas regulators nowadays have springs. This is excluding those few older units, which are weight loaded. This is because the springs and diaphragms are now the most commonly utilized loading elements in new or modern regulators. In considering this element, the spring rate is very significant to consider. This is specifically about the number of force, in pounds, needed in order to compress the spring by an inch. Aside from the spring, the material, wire or spring diameter, free length and coils are important factors too.
Thirdly and lastly, there are various devices available as measuring elements for our gas cylinder regulator. Among the most common are the manometer and pressure gauge. Aside from that, the bellows and bourdon tubes are another forms of measuring elements, which are usually used in regulators with automatic control systems. These are more reliable and accurate compare to the manual types. However, this may have some setbacks too. For example, using this will also require you to have some types of auxiliary devices in order to supplement them. Moreover, the diaphragm is another form of this measuring element that is universally being used.
