         对夹式止回阀是一种通用单向流体阀门。其重量轻衬里阀门，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， 疏水阀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。

 　　安装注意事项　　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 　　安装在垂直放置的管路中。电动执行器对于水平放置的管路，垂直放置对夹式止回阀 　　在对夹式止回阀和蝶阀之间使用一个伸缩管，电磁阀千万不要将其与其它阀门直接相连 　　在阀板操作半径范围内，避免加入管接头和阻塞物 　　不要在对夹式止回阀的前面或者后面安装一个变径管 　　在弯头附近安装对夹式止回阀时，特殊阀门要注意留有足够大的空间 　　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

        Wafer Check Valve is a universal one-way flow valve. Its light weight, small size, easy to install between flanges, Balance valves valve springs and within two semicircular board composition, with a spring pin fixed to the body deformation of the valve plate closed, fluid pressureSafety valves exerted by the spring to open deformation quickly, this can protect the damaged pipe from the water hammer. Installation Notes Should pay attention to put pipes onMud Valves the folder-type check valve in the direction of fluid flow through the line Installed in the vertical placement of the pipe. For the horizontal pipe, vertical placement of the clip-type check valve In the check valve and butterfly clipGauge Valves between the use of a telescopic tube, do not be directly connected with other valves Operation in the disc radius, to avoid the added fittings, and obstructions Do not check valve on the folderGlobe Valves in front of or behind the installation of a tapered tube In the elbow near the check valve installed on the folder, you should pay attention to leave enough space Exports in the pump check valve installed on the folder, at least out six times the diameter of the valve disc space to ensure that the final effect by the fluid
