2)水箱升降气缸5和密封气缸15固定安装在气缸顶板2下部，水箱升降气缸5的活塞杆与水箱6相连，水箱6与水缸8用连接水管7连通；2) The water tank lifting cylinder 5 and the sealing cylinder 15 are fixedly installed on the lower part of the cylinder top plate 2, the piston rod of the water tank lifting cylinder 5 is connected to the water tank 6, and the water tank 6 and the water tank 8 are communicated with the connecting water pipe 7;

4)气密仪1设置在气缸顶板2上，用检测进气管16与密封压头14相连通。4) The air tightness instrument 1 is arranged on the top plate 2 of the cylinder, and communicates with the sealing pressure head 14 through the detection intake pipe 16 .
它在使用时的工作原理如下：It works as follows when used:
先用干检方式检测被测工件的气密性是否优良，有没有漏气；如果被测工件的气密性不好，有漏气，再进一步采用水检方式来检测确定被测工件的具体泄漏点。First use the dry inspection method to detect whether the airtightness of the workpiece under test is good or not, and whether there is any air leakage; leak point.
干检时使水缸8内处于无水状态，将被测工件13置于水缸8底部，扳动干检阀9使压力气源通过密封气缸气管11进入密封气缸15的上部，从而向下推动气缸活塞，使与活塞杆相连的密封压头14随即下降，压紧并密封工件的容积口；再按动气密仪1的按钮开关，使气源通过检测进气管16和密封压头14对被测工件13的容积空腔充气、检测，容积空腔无泄漏时则气密仪1显示“合格”字样并亮起绿灯；这时再反向扳动干检阀9使压力气源通过密封气缸气管11进入密封气缸15的下部，从而向上推动气缸活塞，使密封压头14松开取出工件，换上另一被测工件重复以上操作进行检测。如果当一个工件被检测结果显示出“不合格”时，就采用水检方式查找漏点以便修复。During the dry inspection, make the water tank 8 in an anhydrous state, place the workpiece 13 under test at the bottom of the water tank 8, and pull the dry inspection valve 9 so that the pressure air source enters the upper part of the sealed cylinder 15 through the air pipe 11 of the sealed cylinder, thereby downward Push the cylinder piston, so that the sealing head 14 connected with the piston rod will drop immediately, press and seal the volume port of the workpiece; The volume cavity of the workpiece 13 to be tested is inflated and tested. When there is no leakage in the volume cavity, the air tightness instrument 1 displays the word "qualified" and lights up the green light; Cylinder air pipe 11 enters the lower part of sealing cylinder 15, thereby pushing up the cylinder piston, so that the sealing pressure head 14 is loosened to take out the workpiece, replace it with another workpiece to be tested and repeat the above operations for detection. If a workpiece is detected as "unqualified", the water inspection method is used to find the leak point for repair.
水检时，扳动水检阀10使压力气源通过水箱升降气缸气管12进入水箱升降气缸5的下部，从而向上推动活塞使水箱6随活塞杆的回缩而上升到箱底略高于水缸8的口部位置，此时水箱6内的水因落差通过连接水管7流入水缸8内而淹没被检测工件，随后按动气密仪1的按钮开关使气源通过检测进气管16和密封压头14再次对被测工件的容积空腔充气，气体必然经过被测工件的泄漏点冒出肉眼可观察到的气泡，从而找准泄漏点并作好标记；再反向扳动水检阀10，使水箱6顶部略低于水缸8的缸底，此时水缸8内的水因落差快速流回水箱6内，水缸8内处于无水状态，水检完成。During the water inspection, pull the water inspection valve 10 so that the pressure air source enters the lower part of the water tank lifting cylinder 5 through the water tank lifting cylinder air pipe 12, thereby pushing the piston upward to make the water tank 6 rise to the bottom of the tank with the retraction of the piston rod slightly higher than the water tank 8, at this time, the water in the water tank 6 flows into the water tank 8 through the connecting water pipe 7 to submerge the workpiece to be detected due to the drop, and then press the button switch of the air tightness instrument 1 to make the air source pass through the detection inlet pipe 16 and the sealing pressure The head 14 inflates the volume cavity of the measured workpiece again, and the gas must pass through the leakage point of the measured workpiece to produce bubbles that can be observed by the naked eye, so as to locate the leak point and make a mark; then reversely turn the water detection valve 10 , the top of the water tank 6 is slightly lower than the bottom of the water tank 8, and now the water in the water tank 8 flows back in the water tank 6 because of the drop, and the water tank 8 is in an anhydrous state, and the water inspection is completed.
