产品简介

法兰全启式安全阀

详细介绍

一、法兰全启式安全阀参数：

产品名称：	全启式安全阀
产品型号：	A42Y、A44Y、A48Y
产品口径：	DN32~200
产品压力：	0.6~32.0Mpa
产品材质：	铸钢、不锈钢、合金钢等

二、法兰全启式安全阀概述：
安全阀的主要参数是排量，这个排量决定于阀座的口径和阀瓣的开启高度，由开启高度不同，又分为微启式和全启式两种。微启式是指阀瓣的开启高度为阀座喉径的1/40～l/20。全启式是指阀瓣的开启高度为阀座喉径的1/4。全启式安全阀：应用在蒸汽介质是一般有一个突然全开动作，此突开动作时的压力为整定压力（突跳压力）；应用在空气介质是，先打开与进口压力增加开高呈比例升高，然后再突然起跳全开，称二段式开启；一般不可用于液体介质。微启式安全阀：先打开与进口压力增加开高呈比例升高，压力下降时亦随进口压力下降开高呈比例下降，一般用于液体介质（或保护管道时用于可压缩气体）。
