Description

一种适用于空气的对夹双瓣止回阀
技术领域
本发明涉及一种适用于空气的对夹双瓣止回阀，属于机械零件制备技术领域。
背景技术
止回阀用于安装在管路系统中，主要作用是为了防止介质倒流，止回阀是一种依靠介质压力开启和闭合的自动阀门。适用于空气流动的止回阀在闭合过程中两片阀瓣的夹角为180°，此种止回阀在使用过程中从全开状态到全关状态，扭簧的行程为180°，因此当气流通过止回阀时阻力损失较大，且当气流较小时止回阀使用造成许多不便。
发明内容
本发明的目的是为了解决现有技术中止回阀的两片阀瓣间夹角为180°，从关闭到打开扭簧的扭程大，气流损失较大的问题，提供了一种结构简单，设计紧凑的适用于空气的对夹双瓣止回阀。
本发明采用如下技术方案：一种适用于空气的对夹双瓣止回阀，包括阀体，所述阀体的中部设置有阀杆，所述阀杆上套设有第一扭簧组和第二扭簧组，所述第一扭簧组的一端与阀杆相连接，所述第一扭簧组的另一端固定于第一阀瓣上，所述第二扭簧组的一端与阀杆相连接，所述第二扭簧组的另一端固定于第二阀瓣上，所述第一阀瓣和第二阀瓣间的夹角为120～150°。
进一步的，所述第一阀瓣和第二阀瓣与阀体接触的边缘处分别设置有密封圈。
进一步的，所述第一扭簧组和第二扭簧组的长度为第一阀瓣和第二阀瓣长度的0.5～0.9倍。
进一步的，所述第一扭簧组和第二扭簧组分别包括至少2个弹簧。
本发明结构简单，设计紧凑，第一阀瓣和第二阀瓣之间的夹角为120°，在第一扭簧组和第二扭簧组的辅助下进行止回阀的关闭，第一扭簧组和第二扭簧组的的扭程更小，关阀速度快，只需较小的压差即能完全打开。
附图说明
图1为本发明的结构示意图。
附图标记：阀体1、阀杆2、第一扭簧组3、第二扭簧组4、第一阀瓣5、第二阀瓣6、密封圈7。
具体实施方式
下面将结合附图对本发明作进一步的描述。
如图1所示，一种适用于空气的对夹双瓣止回阀，包括阀体1，阀体1的中部设置有阀杆2，阀杆2上套设有第一扭簧组3和第二扭簧组4，第一扭簧组3的一端与阀杆2相连接，第一扭簧组3的另一端固定于第一阀瓣5上，第二扭簧组4的一端与阀杆2相连接，第二扭簧组4的另一端固定于第二阀瓣6上，第一阀瓣5和第二阀瓣6间的夹角为120°，第一阀瓣5和第二阀瓣6与阀体1接触的边缘处分别设置有密封圈7，第一扭簧组3和第二扭簧组4分别包括2个弹簧，第一扭簧组3和第二扭簧组4的长度为第一阀瓣和第二阀瓣长度的0.5～0.9倍。
工作原理与方法：将阀体1安装于鼓风机后的管路中，当鼓风机运转后，有气流通过止回阀，气压差增大，第一扭簧组3和第二扭簧组4处于压紧状态第一阀瓣5和第二阀瓣6在气流压差的作用下打开，形成畅通的通路。本发明中第一阀瓣5和第二阀瓣6间的夹角为120°，在打开过程中两个扭簧组的弹力减小，在较小的压差下即能实现完全打开，同时也减少了气流在流经对夹双瓣止回阀时所产生的能量损耗。当鼓风机关闭后，无气流通过，第一扭簧组3和第二扭簧组4处于松弛状态第一阀瓣5和第二阀瓣6在无压差的作用下与阀体1接触，第一阀瓣5和第二阀瓣6之间保持120°的夹角，止回阀处于闭合状态，防止气体倒灌至鼓风机。
