Description

一种用于风管阀的叶片
技术领域
本发明涉及风管阀技术领域，特别是一种适用于风管阀、密封性能好的叶片。
背景技术
风管阀在现代建筑中普遍使用，大量安装在通风、空调及消防排烟通风系统的送、回风管路上，平时呈开启或关闭状态，遇到检修或者火灾引起环境温度异常时能够关闭或开启，起到阻断空气流通的作用。其中，漏风量是风管阀一个重要的参数，同时也是目前风管阀3C认证考察的重要性能。目前市场上的风管阀采用的叶片结构，关闭后叶片与叶片之间存在缝隙，密封性不好，在测试中发现漏风量大，无法满足3C认证的要求。
发明内容
本发明的目的是针对现有风管阀存在的关闭后漏风量大、存在安全隐患的不足之处，提供一种密封性好的用于风管阀的叶片。
本发明是通过如下方式完成的：一种用于风管阀的叶片，该用于风管阀的叶片包括叶片本体和簧片，簧片上设有一条折痕，簧片上折痕的一侧为簧片的固定端，簧片上折痕的另一侧为簧片的自由端，簧片的固定端与簧片的自由端之间成一夹角，簧片的固定端固定在叶片本体上。
在所述的一种用于风管阀的叶片中，所述的夹角范围为120°至170°。
在所述的一种用于风管阀的叶片中，所述的簧片采用弹性材料制成。
在所述的一种用于风管阀的叶片中，所述簧片的固定端采用铆接、焊接、粘接中的一种。
在所述的一种用于风管阀的叶片中，所述的焊接采用点焊或缝焊。
在所述的一种用于风管阀的叶片中，所述叶片本体上设有若干根加强筋。
在所述的一种用于风管阀的叶片中，所述叶片本体上的加强筋呈拱形或三角形结构。
在所述的一种用于风管阀的叶片中，所述叶片本体上设有两根加强筋，两根加强筋同向或异向设置。
本发明的叶片本体上设有弹性材料制成的簧片，簧片与相邻叶片或风管阀外壳相接触，用于叶片与叶片、叶片与风管阀外壳之间的密封，提高风管阀的性能。采用本发明的风管阀，其漏风量大大减少，能够满足当前的检测、认证要求，提高安全性能。
本发明与现有的风管阀叶片相比，具有结构巧妙、密封性好、安全性能高的特点。
