进口自力式微压调节阀原理:是一种无需外来能源的节能型产品,利用工艺管道中介质的压力变化与信号进行比较,使被调节介质的压力与执行机构的输出力平衡,以达到稳定压力、差压值。进口自力式微压Self-micro-pressure regulating valve is a energy-efficient product without external energy, use of process piping in the media compared with the signal pressure, so that media pressure and actuator output force balance,In order to achieve stable pressure, differential pressure进口微压自动调节等场合微压阀,采用平衡单座阀,在运行中可任意对设定值进行调整等特点。因而适用于各种工业炉燃烧统燃料气体、石油在制品或油库贮罐保护气体与热处理保护气体的It is a balanced single seat valve, in the operation of any of the settings can be adjusted。Therefore applicable to all kinds of micro-pressure automatic adjustment of the Various industrial furnace combustion of fuel gas systems, oil storage tanks of petroleum products or gas and heat shielding gas protection.
