How to adjust the gas tank valve in order to make the gas stove safe and efficient work? In addition, the market more types of gas tank valve, how to choose? Gas tank valve only decompression effect is not regulated . Regulating pressure is by adjusting the gas tank and gas stove gas switch size adjustment. Gas tank valve selection of well-known brands or through the safety or quality certification company's products will be more insurance. Downward gas tank valve will make the gas tank gas pressure increases, in theory, will make the water heater more powerful and make hot water. However, under normal circumstances, only when the pressure of the gas tank is not enough, the method can be taken. Otherwise, the outlet pressure will be too high to affect the safe use. Pressure relief valve on the gas tank is generally no regulatory role, its role is to make the liquefied gas tank gasified into gas decompression, through the pipeline, open to the gas stove burning. In order to make the gas stove completely burn the gas, the size of the air inlet on the burner should be adjusted. The main components of the gas are propane and butane. Generally, if there is enough oxygen, the flame is blue gas. Propane content starts to use more, as the use of time, propane content decreased, Ding finished content increased, because the carbon four components of the combustion of carbon than the three component combustion requires more air, so at this time may be Appear yellow flame, it is necessary to adjust the air conditioning, so that more air into the combustion to help; and gas molecules will be a small amount of heat decomposition of carbon particles, carbon particles at high temperatures burning light, yellow fire. At this point increase the amount of air intake, and sometimes the flame is still yellow, as Ze choose gas tank valve, of course, to choose a quality assurance of the. Downward gas tank valve will make the gas tank gas pressure increases, in theory, will make the water heater more powerful and make hot water. However, under normal circumstances, only when the pressure of the gas tank is insufficient, the method can be taken. Otherwise, the outlet pressure will be too high to affect the safe use.
