FESTO減壓閥LR-1/8-D-MINI-MPA性能要點(diǎn)
活塞式減壓閥:
該類(lèi)型的減壓閥集兩種閥―導(dǎo)閥和主閥―于一體
。導(dǎo)閥的設(shè)計(jì)與直接作用式減壓閥類(lèi)似。來(lái)自
型的減壓閥,與直接作用式減壓閥相比,在相
同的管道尺寸下,容量和確度(+/-5%)更
導(dǎo)閥的排氣壓力作用在活塞上,使活塞打開(kāi)主
計(jì)就會(huì)利用入口壓力打開(kāi)主閥。因此,這種類(lèi)
閥。如果主閥較大,無(wú)法直接打開(kāi)時(shí),這種設(shè)
高。與直接作用式減壓閥相同的是,減壓閥內(nèi)
部感知壓力,無(wú)須外部安裝傳感線(xiàn)。
消防給水系統(tǒng)中費(fèi)斯托比例減壓閥不宜設(shè)置旁
通管。 在江銀大廈消火栓系統(tǒng)減壓閥施工中初
放水試驗(yàn)測(cè)試壓力則又顯示正常而后檢查時(shí)發(fā)
現(xiàn)是由于設(shè)于旁通管上的閥門(mén)膠襯老化導(dǎo)致滲
期安裝了旁通管在使用約一年半后季檢時(shí)發(fā)現(xiàn)
閥后壓力表與閥前壓力表數(shù)值相同打開(kāi)試驗(yàn)閥
漏而出現(xiàn)靜壓失常動(dòng)、壓正常的現(xiàn)象。 所以為
消防給水系統(tǒng)的供水性。
