工作台1上设置检测装置2，检测装置2包括固定板21和盲板22。如图4至图6中任一附图所示，固定板21固定在工作台1下端面上，盲板22密封固定在固定板21的下端面上，盲板22上开设检测腔221，检测腔221的开口位于盲板22的下端面上，即检测腔221的开口端面为盲板22的下端面，工艺阀杆3沿竖直方向延伸，自上而下滑动穿设在固定板21上，且其前端位于盲板22的检测腔221内，固定板21上开设与外界连通的至少两个流体通道211，本实施例中，流体通道211设置两个，附图4至6中仅示出一个流体通道211，其中一条流体通道211设置排气阀(图中未示出)，另一条流体通道211连接检测流体的流体源，通过低压泵将检测流体泵入检测腔221内。
受第一驱动器41的驱动，检测腔221的开口端面向下移动并抵接在下 方流水线上待检测阀体13的中腔的开口处，待检测阀体13的中腔的开口处为固定法兰131，法兰面与检测腔221的开口端面密封抵接，检测腔221连通待检测阀体13的中腔，检测腔221的开口尺寸等于或者略小于中腔的开口尺寸。按照待检测阀体13和待检测闸板12的不同规格，可以更换与之匹配的盲板22，盲板22的规格可以根据检测腔221的开口尺寸定义。
如图4至图6中任一附图所示，工作台1上端面上设置第二驱动器6，第二驱动器6的驱动端连接工艺阀杆3，第二驱动器6带动工艺阀杆3沿竖直方向往复运动，本实施例中，第二驱动器6采用油缸，位于检测腔221内的工艺阀杆3前端设置固定座31，固定座31两侧设置左右对称的固定部，每一个固定部上固定一个待检测闸板12，固定座31可以为不同规格，即根据待检测闸板12与待检测阀体13规格的不同，可以更换与之匹配的固定座31以便于检测。
如图3所示，工作台1上还设置至少两个限位组件7，本实施例中，限位组件7设置两个，对称分布在工艺阀杆3两侧，任一限位组件7包括第三驱动器71和限位部72，第三驱动器71采用油缸或气缸，限位部72通过连杆固定在第三驱动器71的驱动端，连杆穿设在工作台1上，限位部72位于工作台1下方，受第三驱动器71的驱动，限位部72沿竖直方向上下运动。限位部72采用勾爪，如图2所示，勾爪整体呈梯形结构，勾爪适于勾设在待检测阀体13的开口处法兰131上，将待检测阀体13与检测装置2固定牢固。
本实施例中，还设置第四驱动组件8，以驱动任一限位组件7沿水平方向移动，便于勾爪对法兰131进行夹持，如图3所示，工艺阀杆3两侧的工作台1上分别设置一组第二导向组件9，第二导向组件9与限位组件7对应设置，任一组第二导向组件9包括至少一个第二导轨91，在工作台1上沿水平方向布置，至少一个第二滑块92，滑动设置在第二导轨91上，工艺阀杆3两侧的工作台1上开设对称的长腰孔(图中未示出)，本实施例中， 任一组第二导向组件9中设置两个第二导轨91，两个第二导轨91对称分布在长腰孔两侧，第二滑块92两侧分别滑动设置在两个第二导轨91中，第三驱动器71固定在第二滑块92上，且连杆穿过长腰孔设置。

位于流水线20一侧还设置控制器30，控制器30与第一驱动器41、第二驱动器6、第三驱动器71、第四驱动器以及流体通道的排气阀、输送检测流体的低压泵(图中未示出)、实施保压的高压泵(图中未示出)均电连接。控制器30上还具有指示灯和蜂鸣器等常规设置。
本实施例提供的闸阀检测设备的工作过程为：
工作人员根据待检测阀体13及待检测闸板12的规格预先安装好合适规格的盲板22及工艺阀杆3上的固定座31。当待检测阀体13随流水线20输送至工作台1下方的设定位置，将两片待检测闸板12对称安装在固定座31上，选择预设好的泵验程序(泵验程序依据规格、磅级设定好压力值和保压时间)。
图4至图6依次示意出工艺阀杆3带动待检测闸板12的移动过程，通过控制器30开启第一驱动器41，带动工作台1向下移动，直至检测腔221的开口端面与待检测阀体13的法兰131面抵接，然后启动第二驱动器6，推动工艺阀杆3，带动待检测闸板12继续向待检测阀体13的中腔内部行进，两片待检测闸板12之间形成配合槽，配合槽沿待检测阀体13中腔内壁上 的凸起的导轨筋132移动，将待检测闸板12抵接在阀座133的座圈密封面上。
启动第三驱动器71，将勾爪向下移动至法兰131所在水平面下方，然后启动第四驱动器，第四驱动器推动驱动盘81做旋转运动，带动连接杆82，连接杆82拉动第二滑块92朝向工艺阀杆3运动，同时使下方勾爪水平移动至法兰131下方，再次启动第三驱动器71，带动勾爪向上移动，两侧勾爪同步限位勾紧待检测阀体13。
然后通过流体通道注入检测流体进行密封性检测：
1、低压气密封试验(检测流体为气体)：通过流体通道211向中腔充气，自动增压至试验压力，保压，操作人员向两边密封面喷肥皂水，观测有无气泡逸出，保压时间达到之后，工人按卸压按钮，设备卸压。进入下一程序高压水密封试验。
2、高压水密封试验(检测流体为液体)：由其一流体通道211充水到中腔，另一流体通道211自动开启排气阀，直到空气完全排尽，腔内注满水后，将排气阀关闭，低压水泵自动停止，启动高压泵，当试验介质达到测试所需压力值时，高压泵自动停止，系统自动进入保压计时状态，保压计时结束时，保压计时结束指示灯点亮，同时蜂鸣器鸣响提示。
最后卸压排水，试验结束。工艺阀杆3拉回待检测闸板12，松开勾爪，径向移动到位，工作台1上行至初始位置。泵验人员操作流水线20完成按钮，待检测阀体13及待检测闸板12随托盘自动流向下一工序。
作为实施例1的第一个可替换的实施方式，可以不设置限位组件7、第四驱动组件8和第二导向组件9，仅通过第一驱动器41和第二驱动器6分别驱动盲板22和待检测闸板12抵压在待检测阀体13上，待检测阀体13在流水线20上固定牢固即可。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方 式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本发明创造的保护范围之中。
