| 摘要 | PURPOSE:To prevent abnormal increase in pressure in a gas holder, by providing a valve in an inlet pipe of the gas holder, and controlling an opening/closing operation of the valve according to a signal from a pressure detecting device for detecting pressure in the inlet pipe across the valve. CONSTITUTION:When a piston 2 reaches an upper position of a gas holder 1, a position sensor 7 detects the piston 2 and supplies a signal to a control device 8'. Then, the control device 8' supplies a valve closing signal to a valve 6 to close the valve 6. When pressure in a main pipe 10 becomes higher than that in the gas holder 1, the control device 8' receives a signal from a pressure sensor 9 and supplies a valve opening signal to the valve 6 to open the valve 6. In the case that the piston 2 is located at a lower position of the gas holder 1, the control device 8' receives a signal from the position sensor 7 and supplies a valve opening signal to the valve 6. Accordingly, even if the control device 8' receives a signal from the pressure sensor 9, the valve 6 is maintained open. | ||||||
