AUTOMATIC GAS DISTRIBUTING DEVICE, FOR SUPPLYING A PIPE WITH GAS FROM AN ALTERNATIVE GAS SOURCE, CONTROLLED BY THE DIRECT APPLICATION OF HIGH GAS PRESSURE OF THE SOURCE

摘要

An automatic gas distributing device for delivering gas at a constant predetermined pressure from one of a plurality of high pressure vessels (1, 2) arranged in a ring connection. The device has flow paths (9, 10) corresponding to the high pressure vessels (1, 2), and is controlled by the direct application of the pressures of the gas contained in the associate vessels (1, 2) to the relevant stop valves (27-32). The device automatically set a high pressure vessel having a lower gas pressure than other vessels in operation, and interrupts the high pressure vessel in operation when the gas pressure of the vessel is reduced below a control pressure, and actuate the succeeding vessel.
