一、耐熱鋼楔式閘閥簡單介紹
我公司閘閥是zui常用的截斷閥之一，主要用來接通或截斷管路中的介質(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。
二、耐熱鋼楔式閘閥優(yōu)點：
（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)閘閥時不改變其流動方向，因而流動阻力較小。
（2）啟閉較省力。啟閉時閘板運動方向與介質(zhì)流動方向相垂直。與截止閥相比，閘閥的啟閉較為省力。
（3）介質(zhì)流動方向一般不受限制。介質(zhì)可從閘閥兩側(cè)任意方向流過，均能達到接通或截斷的目的。便于安裝，適用于介質(zhì)的流動方向可能改變的管路中。
