[0031] Touch screen control: The touch screen is an all-in-one touch screen. The relevant control points and parameters are set in the touch screen to realize automatic control of the automatic gas distribution device and achieve the purpose of detecting product gas.
[0032] 1. Set the operating pressure of the compressed air. The automatic air distribution device can only be started when the compressed air pressure is higher than the set pressure. During use, if the compressed air pressure is lower than the set pressure, the automatic air distribution device will automatically stop distributing air.
[0033] 2. Set the operating pressure of liquefied petroleum gas. The automatic gas distribution device can only be started when the liquefied petroleum gas pressure is higher than the set pressure. During use, if the liquefied petroleum gas pressure is lower than the set pressure, the automatic gas distribution device will automatically stop distributing gas.
[0034] 3. Set the operating pressure of the upper limit pressure. When the upper limit pressure is reached, the air solenoid valve and the liquefied petroleum gas solenoid valve will automatically close and stop gas distribution.
[0035] 4. Set the operating pressure of the lower limit pressure. When the lower limit pressure is reached, the air solenoid valve and the liquefied petroleum gas solenoid valve will automatically open and start gas distribution.
[0036] 5. Gas source underpressure alarm: When the compressed air is lower than the set operating pressure, the touch screen pops up "Please check the compressed air underpressure", which will be automatically released when the set operating pressure is exceeded. When the liquefied petroleum gas is lower than the set operating pressure, the touch screen pops up "Please check the liquefied petroleum gas underpressure", which will be automatically released when the set operating pressure is exceeded.
[0037] 6. Three-color indicator light: when the compressed air and liquefied petroleum gas are lower than the operating pressure, the red light flashes; when gas distribution starts, the green light flashes; when gas distribution stops, the yellow light flashes.
[0038] Main features of this application:
[0039] People-oriented: The automatic gas distribution device controlled by the touch screen will automatically operate the gas distribution when the gas source pressure is higher than the set operating pressure. It will automatically stop and alarm when it is lower than the set operating pressure. There is no need for relevant personnel to monitor or maintenance personnel to check for faults, saving human resources.
[0040] Efficient and fast: The automatic gas distribution device controlled by the touch screen starts automatic operation with one button, and automatically alarms when the air and liquefied gas are underpressure. There is no need to check for faults. Replacing the gas source will eliminate the fault and continue operation.
[0041] Safe and reliable: The automatic gas distribution device controlled by the touch screen converts the high-pressure gas source into medium-pressure gas output through decompression and pressure setting, increasing the safety of gas use.
[0042] Energy saving and environmental protection: The automatic gas distribution device controlled by the touch screen saves users 85% of investment costs and 80% of gas costs. Air and liquefied petroleum gas are mixed for use, which reduces the use of liquefied petroleum gas and emissions, contributing to the country's energy reserves.
[0043] The touch screen controlled automatic gas distribution device is a device that can simulate the conversion of compressed air and liquefied petroleum gas into natural gas or artificial gas. At present, it is mainly used in the production lines of household and commercial gas combustion appliances and laboratory testing products: In view of the fact that natural gas and artificial gas are not yet widely popular, or natural gas and artificial gas are already available in the area, but the account opening fee is too high, resulting in large investment project costs, the advantage of using this touch screen controlled gas distribution device is that it saves 85% of the investment cost compared to opening an account for natural gas or artificial gas pipelines. When used in the production line of household and commercial gas combustion appliances, when testing natural gas products, the ratio of compressed air is 45% and liquefied petroleum gas is 55%. After mixing in the mixing tank, it is output to the production line testing product. When testing artificial gas products, the ratio of compressed air is 35% and that of liquefied petroleum gas is 65%. After mixing in a mixing tank, the gases are output to the production line for testing. When used in laboratory testing of household and commercial gas combustion appliances, the ratio of compressed air is 45% and that of liquefied petroleum gas is 55%. When testing artificial gas products, the ratio of compressed air is 35% and that of liquefied petroleum gas is 65%. The laboratory uses a mixed simulated gas to test gas combustion appliances. After preheating for 15 minutes, the gas is converted to (methane or standard artificial gas) for testing and sampling. The gas combustion appliances are sampled after being preheated with a simulated gas mixture of compressed air and liquefied petroleum gas. The entire process can save 80% of gas costs compared to using (methane or standard artificial gas) throughout the process.
