一、进口微压气体减压阀概述
进口微压气体减压阀,(Micro pressure gas reducing valve)也叫微压气体调压阀,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,使被调节介质的力与执行机构的输出力平衡,以达到气体减压稳压的阀门。进口微压气体减压阀主要用于控制阀前压力小于0.2MPa,阀后最低可用5KP千帕的场合,适用于各种工业炉燃烧系统控制两种燃料气体混合比流量或用于氢冷发电机组密封油系统中,同时,还可用于各种工业气体的减压、稳压或泄压的自动控制。
Micro pressure gas reducing valve, also known as micro pressure gas reducing valve, is an energy-saving product that does not require external energy. It compares the pressure changes of the medium in the process pipeline with the signal to balance the force of the regulated medium with the output force of the actuator, in order to achieve gas pressure reduction and stabilization. The imported micro pressure gas pressure reducing valve is mainly used in situations where the pressure in front of the valve is less than 0.2MPa and the minimum usable pressure behind the valve is 5KP kilopascals. It is suitable for controlling the mixing ratio flow rate of two types of fuel gases in various industrial furnace combustion systems or for sealing oil systems in hydrogen cooled generator sets. At the same time, it can also be used for automatic control of pressure reduction, stabilization, or relief of various industrial gases.
二、进口微压气体减压阀产品特征
1、进口微压气体减压阀调节弹簧设计在薄膜执行机构上方,利于现场调试。
2、进口微压气体减压阀无填料,阀杆上、下活动是不存在摩擦,上密封绝对可靠。
3、执行机构敏感元件极为灵敏,极微小的压力变化会被感测出来。
4、阀体为四通形式,因而K、B型可通用一种阀体。
5、进口微压气体减压阀平衡型结构,不受阀前压力影响。
