進(jìn)口不銹鋼減壓閥,(德國(guó)OLES奧萊斯閥門)
【進(jìn)口不銹鋼減壓閥】結(jié)構(gòu)特點(diǎn):
自力式不銹鋼減壓閥產(chǎn)品概述自力式不銹鋼減壓閥由兩種作用方式,*種為活塞式,第二種為薄膜式。不銹鋼減壓閥也是一種常用型減壓閥在鍋爐上、電站上用的偏多,屬于一種多功能減壓閥,利用彈簧彈性來進(jìn)行減壓。不銹鋼減壓閥在成本上是普通安全閥的2-3倍,所以不是由于介質(zhì)、溫度問題大家都不會(huì)選用這么好材質(zhì)的減壓閥。本減壓閥通過自動(dòng)調(diào)節(jié)閥瓣開度,實(shí)現(xiàn)對(duì)管道介質(zhì)減壓穩(wěn)壓的作用,保護(hù)閥后設(shè)備的正常運(yùn)行。
Self-powered stainless steel pressure relief valve product overview Self-powered stainless steel pressure relief valve from two ways of action, the first is piston type, the second is film type. Stainless steel pressure relief valve is also a common type of pressure relief valve used on boilers and power plants, belonging to a multi-functional pressure relief valve, using spring elasticity to reduce pressure. Stainless steel pressure relief valves are 2-3 times more expensive than ordinary safety valves, so it is not because of medium and temperature problems that nobody will choose such a good material pressure relief valves. By automatically adjusting the disc opening, the pressure relief valve realizes the function of pressure relief and stabilization for pipeline medium, and protects the normal operation of the equipment behind the valve.
自力式不銹鋼減壓閥操作須知說明:
(1)不許用裸手直接接觸閥體,否則可能造成燙傷。 注意 (1)在操作前,應(yīng)首先關(guān)閉減壓閥前截?cái)嚅y,并利用旁路去除全部異物和鐵銹,否則可能造成減壓閥故障,無法正常工作。 (2) 通過旁路管線的二次側(cè)壓力必須低于設(shè)定壓力。否則由于通過旁路管線的二次側(cè)壓力高于設(shè)定壓力,引起安全閥起跳。 (3) 當(dāng)調(diào)整壓力時(shí),慢慢地輕動(dòng)調(diào)整螺絲,不當(dāng)?shù)恼{(diào)整操作可能行成水擊或砰砰作響聲等,對(duì)減壓閥或其他設(shè)備造成損壞。 (4) 管線中的凝結(jié)水要*排除,當(dāng)長(zhǎng)時(shí)間不用時(shí),應(yīng)關(guān)閉減壓閥前后的截止閥。(管路中產(chǎn)生的鐵銹可能造成故障) (5) 對(duì)于帶手柄的型號(hào),確實(shí)需要進(jìn)行手動(dòng)操作時(shí),應(yīng)首先按下手柄,再進(jìn)行轉(zhuǎn)動(dòng)調(diào)整;此時(shí),不可用力過大或轉(zhuǎn)動(dòng)過快,以免損壞手柄
【進(jìn)口不銹鋼減壓閥】安裝說明:
(1)閥在氣體或低粘度液體介質(zhì)中使用時(shí),通常自力式壓力調(diào)節(jié)閥為直立安裝在水平管上,當(dāng)位置空間不允許時(shí)才倒裝。 (2)閥在蒸汽或高粘度液體介質(zhì)中使用時(shí),通常自力式壓力調(diào)節(jié)閥為倒立安裝在水平管上,冷凝器(蒸汽用自力式)應(yīng)高于調(diào)壓閥的執(zhí)行機(jī)構(gòu)而低于閥前后接管。使用前冷凝器應(yīng)灌滿冷水,以后約3個(gè)月灌水一次。 (3)取壓點(diǎn)應(yīng)取在調(diào)壓閥適當(dāng)位置,閥后調(diào)壓應(yīng)大于6倍管道直徑。 (4)為便于現(xiàn)場(chǎng)維修及操作,調(diào)壓閥四周應(yīng)留有適當(dāng)空間。 (5)當(dāng)介質(zhì)為潔凈氣體或液體時(shí),閥前過濾器可不安裝。 (6)調(diào)壓閥通徑過大(DN≥100時(shí)),應(yīng)有固定支架。 (7)當(dāng)確認(rèn)介質(zhì)很潔凈時(shí),過濾器可不安裝。 (8)位置實(shí)在不允許時(shí),傍通閥(手動(dòng))可以省略(我們不*)。 (9)閥組后根據(jù)需要用戶可選配止回閥、安全閥等 (10)自力式閥根據(jù)計(jì)算通徑可以小于管道直徑,而截止閥或切斷球閥、傍通閥、過濾器則不能小于管道直徑。
