進口低溫減壓閥,(德國OLES奧萊斯閥門)
【進口低溫減壓閥】詳細說明:
主要在低溫貯槽上內(nèi)部壓力改變而起保護作用,它也可以在低溫下氣體的壓力降低控制。該閥結(jié)構(gòu)緊湊、體積小、重量輕。調(diào)節(jié)靈敏,穩(wěn)定性好。 此類主要用于液氮、液氮、液氬介質(zhì)系統(tǒng)上,具有調(diào)壓穩(wěn)定、密封可靠及耐壓等優(yōu)點。,也叫低溫調(diào)壓閥,低溫壓力調(diào)節(jié)閥,低溫減壓穩(wěn)壓閥,是指采用經(jīng)深冷處理的低溫不銹鋼材料,在低溫貯槽上用于將低溫液體(液氧,液氮,液氬,液化天然氣,LO2、LN2、LAR、LNG等)的壓力保持在某一規(guī)定范圍內(nèi),也就是將閥前進口的高壓力減到并穩(wěn)定在閥后出口所需要的壓力值的閥門。是低溫管道上*的閥門之一
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.
【進口低溫減壓閥】特征:
1、結(jié)構(gòu)緊湊、體積小、重量輕。調(diào)節(jié)靈敏,穩(wěn)定性好。
2、帶可調(diào)裝置,壓力調(diào)節(jié)方便
3、閥門經(jīng)低溫深冷處理,可耐-196℃低溫
4、墊片具有在常溫下、低溫狀態(tài)及溫度變化下能可靠密封性和復(fù)原性,密封性能好
【進口低溫減壓閥】安裝說明:
1:閥門或管件法蘭蓋板不能隨意拆開,除非已經(jīng)準(zhǔn)備和管路連接,否則ptte法蘭面可能因為溫差、異物刮傷或扭曲變形而影響密封性能,如因檢測需求移動蓋板,也必須在檢測后迅速將蓋板復(fù)位,以保護ptfe法蘭面。
2:如果在系統(tǒng)使用中,如在較低的溫度下發(fā)生泄漏,應(yīng)首先將系統(tǒng)溫度降低至室溫后,再查明原因,進行維修工作。
3:不允許在冷門用管道上進行任何高溫焊接工作,以免造成閥門*損害。
4;安裝時,法蘭螺母應(yīng)當(dāng)按照對角線方向一次均勻旋緊,并配以適當(dāng)力拒:
(1) 若法蘭密封面發(fā)生泄漏,并且泄漏位置螺母已經(jīng)緊鎖,此時應(yīng)當(dāng)放松泄漏位置螺母半圈,再將其對側(cè)以同樣力拒再次鎖緊。
(2) 若上述方法仍未止漏時,應(yīng)該檢查ptfe法蘭面是否有凹凸壓痕、劃傷,屆時可用細紗布、砂紙予以整平,重新連接。
5閥門與管件應(yīng)存放于干燥通風(fēng)的室內(nèi),嚴禁堆疊放置。
6手動操作時,不允許借助其他杠桿加力強行開、關(guān)閥門。
