3DREP、3DREPE型-REXROTH比例閥力士樂減壓比例閥3DREPE型價格

REXROTH比例閥產(chǎn)品特點(diǎn)

由油缸、閥體兩部分組成。而節(jié)流孔板和高壓調(diào)節(jié)閥設(shè)計(jì)為一體，閥門開關(guān)排泄流量和降壓由液壓缸行程控制。能任意調(diào)整排泄壓力及流量，安全，方便。

比例減壓閥:壓降從50兆帕至于1.6兆帕，可以調(diào)節(jié)排泄壓力。

REXROTH比例閥工作原理

導(dǎo)閥的開啟都是利用頂部的調(diào)節(jié)螺栓順時針方向擰動，使彈簧縮產(chǎn)生的彈力，使導(dǎo)閥膜片向下凹陷，作用在導(dǎo)閥連桿上的力，使之向下位移打開導(dǎo)閥。當(dāng)導(dǎo)閥開啟后，上游進(jìn)汽管段A腔的蒸汽通過α通道(供汽調(diào)節(jié)通道)，經(jīng)過導(dǎo)閥進(jìn)入導(dǎo)閥環(huán)形汽腔，由β通道直接送到下面的活塞汽缸上腔。在A腔蒸汽不斷的供給下，壓力持續(xù)升高，推動活塞下行打開主閥，這時蒸汽*從A腔流至B腔。當(dāng)下游出口管段B腔負(fù)荷滿足的情況下，余多的蒸汽又使B腔內(nèi)的壓力不斷升高。不斷升高的壓力通過γ通道(壓力感應(yīng)通道)反饋到導(dǎo)閥膜片下腔，使導(dǎo)閥膜片向上突起，克服了上部調(diào)節(jié)彈簧的壓力，導(dǎo)閥被關(guān)小或關(guān)閉。從而，關(guān)小或關(guān)閉來自上游α通道的蒸汽源。當(dāng)活塞汽缸上腔壓力下降時，在下面復(fù)位彈簧的作用下，主閥被關(guān)小或關(guān)閉，這時B腔內(nèi)的壓力開始下降，這樣周而復(fù)始達(dá)到調(diào)壓的目的。

REXROTH比例閥安裝說明

1、在比例式減壓閥安裝前應(yīng)將管道沖洗干凈并在閥前加裝 Y 型由于管道內(nèi)細(xì)小的雜物都將會導(dǎo)致減壓閥關(guān)閉不嚴(yán)從而引起滲漏而失效導(dǎo)致閥后管網(wǎng)靜壓超高。 過濾器應(yīng)設(shè)置在總管上并去掉堵頭引出裝有閥門的排水管至污水池以便及時排污。

2、比例式減壓閥前后必須設(shè)置閘閥或蝶閥以便檢修時切斷水源。

3、比例式減壓閥宜垂直安裝。 其安裝說明書上說可垂直安裝也可水平安裝但當(dāng)水平安裝時由于重力作用會造成下部的偏心磨損因此宜垂直安裝并應(yīng)按閥體上所示箭頭方向安裝。 江銀大廈消火栓給水自動噴淋系統(tǒng)比例式減壓閥均采用垂直安裝減壓效果明顯功能正常。

4、在高層建筑消防給水中為保證供水的不間斷性減壓閥組宜設(shè)計(jì)為兩組同徑并聯(lián)其中一組工作一組備用。 且應(yīng)與前后管徑相同以便檢修更換時不影響供水。

5、消防給水系統(tǒng)中比例式減壓閥不宜設(shè)置旁通管。 在江銀大廈消火栓系統(tǒng)減壓閥施工中初期安裝了旁通管在使用約一年半后季檢時發(fā)現(xiàn)閥后壓力表與閥前壓力表數(shù)值相同打開試驗(yàn)閥放水試驗(yàn)測試壓力則又顯示正常而后檢查時發(fā)現(xiàn)是由于設(shè)于旁通管上的閥門膠襯老化導(dǎo)致滲漏而出現(xiàn)靜壓失常動、壓正常的現(xiàn)象。 所以為保證消防給水系統(tǒng)的供水可靠性，本人認(rèn)為不應(yīng)設(shè)置旁通管。

6、在比例式減壓閥前后宜裝設(shè)壓力表可直接用于觀察減壓閥前后壓力的變化監(jiān)察減壓閥的減壓效果和工作情況。

7、在高層建筑消火栓系統(tǒng)的比例式減壓閥后一般宜設(shè)置可曲撓橡膠接頭。 一方面為便于減壓閥安裝拆卸同時亦可起到伸縮節(jié)作用。
