When the oil tank is carried out and unloaded, the pneumatic controller is used to open the improvement valve to quickly flow the oil and gas during the loading and uninstallation process of oil products, recycle recycling, maintain the pressure of oil tanks to balance, and effectively seal it during transportation.
