產(chǎn)品詳情
低溫閘閥
產(chǎn)品型號(hào):DZ40Y
產(chǎn)品口徑:DN15-600
產(chǎn)品壓力:0.6~10.0Mpa
產(chǎn)品材質(zhì):低溫鋼、合金鋼等
1.低溫閘閥簡(jiǎn)介
閘閥是最常用的截?cái)嚅y之一,主要用來(lái)接通或截?cái)喙苈分械慕橘|(zhì),不適用于調(diào)節(jié)介質(zhì)流量。閘閥適用的壓力、溫度及口徑范圍很大,尤其適用于中、大口徑的管道。
閘閥的主要優(yōu)點(diǎn):
(1)流體阻力小。閘閥閘體內(nèi)部介質(zhì)通道是直通的,介質(zhì)流經(jīng)閘閥時(shí)不改變其流動(dòng)方向,因而流動(dòng)阻力較小。
(2)啟閉較省力。啟閉時(shí)閘板運(yùn)動(dòng)方向與介質(zhì)流動(dòng)方向相垂直。與截止閥相比,閘閥的啟閉較為省力。
(3)介質(zhì)流動(dòng)方向一般不受限制。介質(zhì)可從閘閥兩側(cè)任意方向流過(guò),均能達(dá)到接通或截?cái)嗟哪康?。便于安裝,適用于介質(zhì)的流動(dòng)方向可能改變的管路中。
