Self-styled refueling gun pressure sensing system

fuel transfer hand pump for kerosene, gasoline, diesel and other light oil filling operations. It has a separate body with the gun body of the sealed pressure of the working system, when the oil gun main valve to open high-speed oil flow through the return valve, due to the special structure of the valve assembly design will make pressure inside the system pressure.
temperature probe calibration When it is in normal working condition, its pressure-sensitive system will be through the pressure inside the tubing in the pipeline to continue to get gas to maintain the pressure-sensitive diaphragm up and down the basic pressure in a state of balance. When the filling surface rises and closes the ventilation port (at this time the container is full) pressure within the system will quickly increase the negative pressure, pressure sensor on both sides of the pressure loss on both sides of the pressure (upper negative pressure) The diaphragm will drive the switch card to the negative side of the movement of the bolt off the file, which in 0.3 seconds self-styled refueling gun to complete self-styled closure action.
