Description
技术领域technical field

背景技术Background technique
对于单体滤瓶的密封性检测方法有很多，最为常见的是一种浸水式检测方法，这种检测方式只需要将待检测的容器放置在水里，如果有气泡产生，则说明密封性不好，如果没有，则判定为密封性合格。There are many testing methods for the airtightness of single filter bottles, the most common is a water immersion testing method, this testing method only needs to place the container to be tested in water, if there are bubbles, it means that the airtightness is not good Well, if not, it is determined that the sealing is qualified.
上述的检测方式虽然操作简便，但是存在一些问题，首先单体滤瓶过滤系统体积有大有小，如果需要检测较大的单体滤瓶过滤系统就需要更大的容器，同时为了将单体滤瓶淹没，会浪费更多的水。Although the above-mentioned detection method is easy to operate, there are some problems. First, the volume of the monomer filter bottle filtration system is large or small. If a larger monomer filter bottle filtration system needs to be detected, a larger container is required. The filter bottle floods, and more water is wasted.
而且如果在检测过程中单体滤瓶过滤系统内进水，不仅会污染滤芯，还有可能将滤芯损坏，所以单体滤瓶过滤系统不宜采用这种检测方式。Moreover, if water enters the single filter bottle filtration system during the detection process, it will not only pollute the filter element, but may also damage the filter element, so this detection method is not suitable for the single filter bottle filtration system.
最后在判定气密性的时候，由于浸泡的时间和气泡是否可见都将影响最终的检测结构，主观因素影响较大。Finally, when judging the airtightness, since the soaking time and whether the bubbles are visible will affect the final detection structure, subjective factors have a greater influence.

本发明所述的单体滤瓶过滤系统的密封性检测装置在判断单体滤瓶的密封性时采用了气密性检测仪6进行判定，如果仿型腔1内气压发生变化，说明单体滤瓶过滤系统2的密封性不合格，不合格警报灯8会亮起来，如果仿型腔1内气压没有发生变化，那么说明单体滤瓶过滤系统2的密封性合格，合格显示灯7亮起来。The sealing detection device of the monomer filter bottle filtration system according to the present invention adopts the air tightness detector 6 to judge when judging the tightness of the monomer filter bottle. If the air pressure in the imitation cavity 1 changes, it means that the monomer If the airtightness of the filter bottle filtration system 2 is unqualified, the unqualified alarm light 8 will light up. If the air pressure in the imitation cavity 1 does not change, it means that the airtightness of the single filter bottle filtration system 2 is qualified, and the qualified indicator light 7 is on stand up.
作为较佳实施例，所述仿型腔1形状与所述单体滤瓶过滤系统2相同，所述仿型腔1体积大于所述单体滤瓶过滤系统2。仿型腔1要足以容纳单体滤瓶过滤系统2，两者的形状可以相同，也可以不同。As a preferred embodiment, the profile cavity 1 has the same shape as the unit filter bottle filtration system 2 , and the volume of the profile cavity 1 is larger than the unit filter bottle filter system 2 . The imitation mold cavity 1 should be enough to accommodate the single filter bottle filtration system 2, and the shapes of the two can be the same or different.
一种单体滤瓶过滤系统的密封性检测方法，包括上述一种单体滤瓶过滤系统的密封性检测装置全部内容，包括以下几个步骤：A sealing detection method for a single filter bottle filtration system, including the entire content of the above-mentioned sealing detection device for a single filter bottle filtration system, including the following steps:
(1)设定所述真空计11与所述气密性检测仪6的平衡压力和保压时间；(1) setting the balance pressure and the holding time of the vacuum gauge 11 and the air tightness detector 6;
(2)将待检测的所述单体滤瓶过滤系统2的进出口堵住，放置在所述仿型腔1内；(2) Block the inlet and outlet of the monomer filter bottle filtration system 2 to be detected, and place it in the imitation cavity 1;
(3)覆盖所述密封板4，开启所述真空泵9抽取所述仿型腔1内的空气；(3) Cover the sealing plate 4, turn on the vacuum pump 9 to extract the air in the profiling cavity 1;
(4)当所述真空计11检测负压达到平衡压力后，所述真空泵9停止工作，所述真空阀10关闭，进入保压状态；(4) After the vacuum gauge 11 detects that the negative pressure reaches the equilibrium pressure, the vacuum pump 9 stops working, the vacuum valve 10 is closed, and enters the pressure maintaining state;
(5)保压时间结束若所述合格显示灯7闪烁，则所述单体滤瓶过滤系统2无漏气现象，及判定合格；保压时间内若所述不合格报警灯8闪烁，则所述单体滤瓶过滤系统2有漏气现象，及判定为不合格。(5) If the qualified display light 7 flickers at the end of the pressure holding time, the unit filter bottle filtration system 2 has no air leakage, and is judged to be qualified; if the unqualified alarm light 8 flickers during the pressure holding time, then The unit filter bottle filtration system 2 has an air leakage phenomenon, and is judged as unqualified.
使用上述的检测装置进行气密性检测时，真空计11与气密性检测仪6设定的平衡压力根据实际需求而定，仿型腔1内不一定非要抽成真空，只要保证仿型腔1与单体滤瓶过滤系统2内形成足够的压力差即可。When using the above-mentioned detection device for air tightness testing, the balance pressure set by the vacuum gauge 11 and the air tightness detector 6 depends on actual needs. It is sufficient to form a sufficient pressure difference between the cavity 1 and the filter system 2 of the single filter bottle.
作为较佳实施例，所述步骤(4)中的保压时间为5分钟。保压时间不宜过长，这样会使得检测效率下降，保压时间也不宜过短，时间过短仿型腔内难以形成压力变化，会影响检测结果。As a preferred embodiment, the dwell time in the step (4) is 5 minutes. The pressure holding time should not be too long, which will reduce the detection efficiency, and the pressure holding time should not be too short. If the time is too short, it is difficult to form pressure changes in the imitation cavity, which will affect the detection results.
综上所述，本发明所述的单体滤瓶过滤系统的密封性检测装置具有负压检测气密性，不会造成水资源的浪费。In summary, the airtightness detection device of the single filter bottle filtration system of the present invention has negative pressure detection airtightness, and will not cause waste of water resources.
而且本发明所述的单体滤瓶过滤系统的密封性检测装置能够保护单体滤瓶过滤系统2的滤芯，不会对待检测产品造成损伤。Moreover, the leak detection device of the single filter bottle filtration system of the present invention can protect the filter element of the single filter bottle filtration system 2 and will not cause damage to the product to be tested.
本发明所述的单体滤瓶过滤系统的密封性检测装置及检测方法最终有气密性检测仪6判定检测结构，减少了主观因素和人为操作问题对检测结果造成的影响，检测结果更加准确。The airtightness detection device and detection method of the single filter bottle filtration system of the present invention finally have an airtightness detector 6 judgment detection structure, which reduces the influence of subjective factors and human operation problems on the detection results, and the detection results are more accurate. .
