2014/12/16-國标法蘭閘閥使用說明書

一、 概述
閘閥是最常用的截斷閥,主要用來接通或截斷管路中的介質,不适用于調節介質流量。該閥用于工業管道上,通過閘闆的開啟和關閉,控制介質的流動和阻斷。可應用于石油、化工、電力等各種工況的管路上,切斷或接通管路介質。适用介質:水、油品、蒸汽等。
二、 特點
1. 流體阻力小 閥體内部介質通道是直通的,介質流經閥門時不改變其流動方向,因而流動阻力較小;
2. 啟閉省力 啟閉時閘闆運動方向與介質方向相垂直。與截止閥相比,該閥比較省力;
3. 介質流動方向不受限制 介質可從閘閥兩側任意方向流過,均通達到接通或截斷的目的,便于安裝适用于介質的流動方向可通改變的管路中。
4. 密封良好 本閥為強制雙向密封,通過轉動手輪使閥杆帶動閘闆上下移動,閘闆密封面與閥座緊緊壓在一起達到良好的密封效果。
