1,本阀门通路两端须堵塞，存在干燥通风的室内。如长期存放，应经常检查防锈蚀。2,安装前应将阀门清洗干净，并消除在运输过程中造成的缺陷。3,安装时必须仔细核对阀门上的标志和铭牌是否符合使用要求。4,本阀门安装在水平管道上，阀盖向上。

化工,医药对夹式止回阀是一种通用单向流体阀门。其重量轻，体积小，容易安装在法兰之间，阀门内部由两个半圆弹簧和板面组成，用销子固定在阀体上弹簧形变使阀板关闭，流体压力又使其开启弹簧的形变很快，这样能保护管道免受水锤破坏。1、放置管道时应注意使对夹式止回阀的通过方向与流体流向一致；2、安装在垂直放置的管路中。对于水平放置的管路，垂直放置对夹式止回阀；3、在对夹式止回阀和蝶阀之间使用一个伸缩管，千万不要将其与其它阀门直接相连；4、在阀板操作半径范围内，避免加入管接头和阻塞物；5、不要在对夹式止回阀的前面或者后面安装一个变径管；6、在弯头附近安装对夹式止回阀时，要注意留有足够大的空间；7、对夹式止回阀安装注意事项在水泵出口安装对夹式止回阀时，至少流出六倍阀门直径的空间以保证蝶板最终受到流体作用。
