进口低温减压阀,(德国OLES奥莱斯阀门)
【进口低温减压阀】详细说明:
主要在低温贮槽上内部压力改变而起保护作用,它也可以在低温下气体的压力降低控制。该阀结构紧凑、体积小、重量轻。调节灵敏,稳定性好。 此类主要用于液氮、液氮、液氩介质系统上,具有调压稳定、密封可靠及耐压等优点。,也叫低温调压阀,低温压力调节阀,低温减压稳压阀,是指采用经深冷处理的低温不锈钢材料,在低温贮槽上用于将低温液体(液氧,液氮,液氩,液化天然气,LO2、LN2、LAR、LNG等)的压力保持在某一规定范围内,也就是将阀前进口的高压力减到并稳定在阀后出口所需要的压力值的阀门。是低温管道上*的阀门之一
Mainly in the low temperature tank internal pressure changes to play a protective role, it can also be controlled at low temperature gas pressure reduction. The valve has compact structure, small volume and light weight. Adjustment is sensitive and stable. This kind of special purpose is mainly used in liquid nitrogen, liquid nitrogen, liquid argon medium system, with the advantages of stable pressure regulation, reliable sealing and pressure resistance. It is also called cryogenic pressure regulating valve, cryogenic pressure regulating valve and cryogenic pressure reducing pressure stabilizing valve. It refers to the cryogenic stainless steel material used in cryogenic tanks to keep the pressure of cryogenic liquids (liquid oxygen, liquid nitrogen, liquid argon, liquefied natural gas, LO2, LN2, LAR, LNG, etc.) within a specified range, that is, to say, to keep the pressure of cryogenic liquids (liquid oxygen, liquid nitrogen, liquid argon, liquefied natural gas, The high pressure at the front outlet of the valve reduces to and stabilizes the valve at the required pressure at the back outlet. It is one of the indispensable valves in cryogenic pipelines.

【进口低温减压阀】安装说明:
1:阀门或管件法兰盖板不能随意拆开,除非已经准备和管路连接,否则ptte法兰面可能因为温差、异物刮伤或扭曲变形而影响密封性能,如因检测需求移动盖板,也必须在检测后迅速将盖板复位,以保护ptfe法兰面。
2:如果在系统使用中,如在较低的温度下发生泄漏,应首先将系统温度降低至室温后,再查明原因,进行维修工作。
3:不允许在冷门用管道上进行任何高温焊接工作,以免造成阀门*损害。
4;安装时,法兰螺母应当按照对角线方向一次均匀旋紧,并配以适当力拒:
(1) 若法兰密封面发生泄漏,并且泄漏位置螺母已经紧锁,此时应当放松泄漏位置螺母半圈,再将其对侧以同样力拒再次锁紧。
(2) 若上述方法仍未止漏时,应该检查ptfe法兰面是否有凹凸压痕、划伤,届时可用细纱布、砂纸予以整平,重新连接。
5阀门与管件应存放于干燥通风的室内,严禁堆叠放置。
6手动操作时,不允许借助其他杠杆加力强行开、关阀门。
