    • PURPOSE:To prevent release of compressed air in a vessel with discharge of a drain, by connecting a drain discharge valve to the bottom part of the air accumulator vessel and pneumatically providing a lock valve in series to said discharge valve. CONSTITUTION:A drain discharge valve 6 is connected to the bottom part of a vessel 1 of air accumulator, and a lock valve 8 is pneumatically arranged in series to the discharge valve, then a branch pipe 9 divided from an air supply pipe 3 is connected to said lock valve 8. Further a drain release pipe 7 is connected to said lock valve 8. Further there are provided in the vessel 1 an air filler pipe 2 from an air compressor air supply pipe 3, feeding compressed air to air equipments, and a safety valve 4. The lock valve 8 is operated by pressure from the pipe 9 in such a manner that it is in an open state when pressure in the vessel 1 is of a normal valve while it is closed when the pressure is abnormally lowered. In this way, a pressure drop in the air vessel 1 can be automatically held to within a specified value.
    • 目的:为了防止排放排水管容器中的压缩空气释放,通过将排放排放阀连接到空气蓄能器容器的底部,并气动地提供与所述排放阀串联的锁止阀。 构成:排泄阀6连接到储气器的容器1的底部,并且与排气阀串联地设置有锁定阀8,然后将与供气管3分开的分支管9连接 另外,排水排放管7与所述锁定阀8连接。此外,在容器1中设置有空气压缩机空气供给管3的空气填充管2,将压缩空气供给到空气设备,以及 安全阀4.锁定阀8通过管9的压力操作,使得当容器1中的压力为普通阀时处于打开状态,同时在压力异常降低时关闭。 以这种方式,可以将空气容器1中的压降自动保持在规定值内。
