z641气动法兰闸阀概述
下图的是具有气动执行机构（双层气缸，并带有缓冲机构）和手动及其保护机构（手动和可自锁的气动-手动转换装置）的低支架明杆闸阀。该阀由于采用双层气缸结构，其与单气缸式相比，提升力增大了一倍。这就从根本上解决了单气缸气动闸阀的某些阀体内楔死而打不开的弊病。

        下图的z641气动法兰闸阀是具有气动执行机构（双层气缸，并带有缓冲机构）和手动及其保护机构（手动和可自锁的气动-手动转换装置）的低支架明杆闸阀。该阀由于采用双层气缸结构，其与单气缸式相比，提升力增大了一倍。这就从根本上解决了单气缸气动闸阀的某些阀体内楔死而打不开的弊病。而且，由于该阀具备缓冲机构，能有效地减速轻了关闭阀门时，由于活塞下行冲击而造成的阀板车密封面和阀体密封面的磨损，同时，也能避免闸板卡死的现象。为了配合用户实现操作自动化，本公司除供应本系列产品之外，还可单独提供包括支架在内的气缸体，帮助用户对已有的种类繁多的手动闸阀进行改造，将双缸气动执行机构部分安装在手动闸阀的阀体大盖上，即可构成双缸式气动-手动两用闸阀。由于其技术*，性能可靠，操作切换和维修方便，已被石油、化工、冶金、电力、海运等部门作为输送气体、液体介质的管道开闭装置而广泛使用。
