Title:
GAS PRESSURE ADJUSTMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/067991
Kind Code:
A1
Abstract:
Provided is a gas pressure adjustment device capable of stable pressure adjustment while suppressing blasting and ensuring quick response characteristics. The gas pressure adjustment device is provided with: a main pilot governor 21 which is connected to a downstream pipe 13 via a main pilot loop 20, and which controls the operation of a main valve 11 on the basis of a predetermined reference operation control pressure Ps; and a sub-pilot governor 31 which is connected to the downstream pipe 13 via a sub-pilot loop 30 of a separate system from the main pilot loop 20, and which controls an open/close operation of the main valve 11 on the basis of a predetermined pressure Pss higher than the reference operation control pressure Ps. Accordingly, stable gas pressure adjustment can be implemented while ensuring quick response.
