產(chǎn)品概述
結(jié)構(gòu)特點(diǎn)和用途
本系列減壓閥屬于先導(dǎo)式活塞減壓閥。由主閥和導(dǎo)閥兩部分組成，主閥主要由閥座、閥瓣、活塞、缸套、彈簧零件組成。導(dǎo)閥主要由閥座、閥瓣膜片、彈簧、調(diào)節(jié)彈簧等件組成。本產(chǎn)品在普通減壓閥基礎(chǔ)上作了很大改進(jìn)，加大了活塞面積，改變了節(jié)流結(jié)構(gòu)，改變了密封形式，加大了過(guò)流面積等等，從而在提高蒸汽管路、流量、壽命等方面大大改善了性能。本產(chǎn)品主要用于蒸汽管路，適用于流量變化大，進(jìn)口壓力變化大的蒸汽管路。
