其中，阀板4包括第一连接部401、工作部402和第一连接部403，第一连接部401与阀体1的内壁通过转轴10铰接，第一连接部403与连杆9的一端铰接，第一连接部403设置于工作部402远离进水口6的一侧，工作部402能够绕转轴10转动，工作部402能够封堵进水口6。第一连接部401设置于工作部402的一侧，工作部402绕转轴10转动能够开启和关闭进水口6，第一连接部403设置于工作部402上，使工作部402与活塞3相连带动工作部402运动。
在本具体实施方式中，工作部402为半圆形板状结构，第一连接部401和转轴10的数量均为两个，两个第一连接部401均与工作部402的直边面相连，两个第一连接部401之间具有间隙，第一连接部401设置为两个，避免了阀板4在翻转过程中出现偏转、歪斜的问题，提高雨淋报警阀的结构可靠性。
更具体地，控制腔8内设置缸筒11，活塞3可滑动地设置于缸筒11内，设置缸筒11，使得活塞3运动更顺畅，同时降低了阀体1的加工难度，活塞3与缸筒11的内壁相抵接，活塞3与缸筒11之间、缸筒11与阀体1的内壁之间均设置密封元件，避免泄露。
进一步地，进水口6与出水口7同轴设置，进水口6与出水口7同轴，直通式水流通道5减少水流弯道，降低了水利摩阻损失，压力损失小，可承受工作压力高，提高了适用性，缸筒11的轴线与进水口6的轴线相垂直，整体结构呈倒T字形，使用时可水平或直立安装。
为了加强阀板4封堵进水口6时的密封性，阀板4靠近进水口6的一侧设置密封垫12，阀板4封堵进水口6时，密封垫12与阀体1的内壁相抵接，在阀板4的压力作用下，密封垫12背阀板4和阀体1压紧，避免漏水。
在本具体实施方式中，密封垫12通过压盘13固定在阀板4上，压盘13与阀板4通过螺钉固定，压盘13的外径较进水口6的内径小，避免压 盘13和螺钉影响阀板4运动，确保阀板4能够封堵进水口6。
更进一步地，阀盖2上设置连通孔14，控制腔8通过连通孔14分别与消防主管道和泄流管道相连通，连通孔14与消防管道之间、连通孔14与泄流管道之间均设置控制阀，便于控制控制腔8的状态，避免水流混乱影响雨淋报警阀的正常工作。
本发明的雨淋报警阀，采用活塞3带动阀板4的结构，在不需通水的状态下，通过消防主管道向控制腔8内输入压力水，在水压作用下，活塞3顶紧与之相连的阀板4，使阀板4能够封堵进水口6，在雨淋报警阀工作时，控制腔8内的水经由泄流管道释放，水压减小后，阀板4在水流通道5内水力的推动下向上旋转，通过连杆9推动活塞3向上运动，进水口6打开后，水流通过水流通道5由出水口7流出，进行消防灭火，工作完成后，切断控制腔8与泄流管道之间的连通，继续通过消防主管道向控制腔8内通入压力水，在水压作用下，活塞向下移动，带动阀板4转动并封堵进水口6。同时，进水口6与出水口7同轴设置，直通式水流通道5减少水流弯道，降低了水利摩阻损失，压力损失小，可承受工作压力高，提高了适用性，缸筒11的轴线与进水口6的轴线相垂直，整体结构呈倒T字形，使用时可水平或直立安装，本发明的雨淋报警阀结构简单，采用活塞3带动阀板4的结构，提高了可靠性和耐压性。
本发明中应用了具体个例对本发明的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本发明的方法及其核心思想；同时，对于本领域的一般技术人员，依据本发明的思想，在具体实施方式及应用范围上均会有改变之处。综上所述，本说明书内容不应理解为对本发明的限制。
