全自动封胶机常遇到的问题是胶阀问题，下面为大家列出胶阀使用时经常发生的问题的有效方法。
The problem that automatic sealing machine often encounters is the problem of rubber valves. The following is an effective way to solve the problem that often occurs in the use of rubber valves.
1. 胶阀滴漏
1. Rubber valve drip leakage
此种情形经常发生予胶阀关毕以后。95%的此种情形是因为使用的针头口径太小所致。太小的针头会影响液体的流动造成背压, 结果导致胶阀关毕后不久形成滴漏的现象. 过小的针头也会影响胶阀开始使用时的排气泡动作.只要更换较大的针头即可这种问题。锥形斜式针头产生的背压少, 液体流动顺畅。液体内空气在胶阀关毕后会产生滴漏现象, 好是预先排除液体内空气,，或改用不容易含气泡的胶.或先将胶离心脱泡后在使用。
This often happens after the rubber valve is closed. 95% of the cases were due to the small caliber of the needle used. Too small needles can affect the flow of liquid and cause back pressure, resulting in drip leakage shortly after the closure of the rubber valve. Too small needles can also affect the action of exhausting bubbles when the rubber valve starts to use. This problem can be solved by replacing larger needles. Conical oblique needle produces the least back pressure and the smoothest flow of liquid. The air in the liquid will drip after the rubber valve is closed. It is better to exclude the air in the liquid beforehand, or change to a rubber which is not easy to contain bubbles, or to defoam the rubber centrifugally before using it.
2. 出胶大小不一致
2. The size of the glue is not the same.
当出胶不一致时主要为储存流体的压力筒或空气压力不稳定所产生。进气压力调压表应设定于比厂内低压力低1015psi.，压力筒使用的压力应介于调压表中间以上的压力, 应避免使用压力介于压力表之中低压力部分。胶阀控制压力应少60psi以上以确保出胶稳定。后应检查出胶时间.若小于15/1000秒会造成出胶不稳定.，出胶时间愈长出胶愈稳定。
When the gum is discharged inconsistently, it is mainly caused by unstable pressure cylinder or air pressure for storing fluid. The intake pressure regulator should be set at 10 to 15 psi below the lowest pressure in the factory. The pressure used in the pressure cylinder should be above the middle of the pressure regulator, and the pressure between the middle and low pressure parts of the pressure gauge should be avoided. The control pressure of the rubber valve should be at least 60 psi to ensure the stability of the rubber tapping. Finally, check out the gel time. If less than 15/1000 seconds will cause unstable gel production. The longer the gel production time, the more stable the gel production.

3. 流速太慢
3. Flow velocity is too slow
流速若太慢应将管路从1/4” 改为3/8”。管路若无需要应愈短愈好。除了改管子,还要改出胶口和气压,这样完全加快流速。
If the flow rate is too slow, the pipeline should be changed from 1/4"to 3/8". The shorter the pipeline is, the better. In addition to pipe modification, the rubber outlet and air pressure should also be changed to completely accelerate the flow rate.
4. 流体内的气泡
4. Bubbles in Fluid
过大的流体压力若加上过短的开阀时间则有可能将空气渗入液体内. 方法为降低流体压力并使用锥形斜式针头。
Excessive fluid pressure and too short valve opening time may infiltrate air into the liquid. The solution is to reduce fluid pressure and use tapered oblique needle.
5. 瞬间胶在胶阀` 接头` 及管路上堵塞
5. Instantaneous glue blockage in rubber valve `joint'and pipeline
此种情形主要因过多的湿气或重复使用过的瞬间胶. 应确保使用新鲜的瞬间胶. 将管路以未含湿气的Aceton丙酮彻底清洗过. 使用的空气应确定完干燥且于厂内空压与胶阀系统间加装过滤器. ( 以上方法如仍然无效, 则应使用氮气. ) 。
This situation is mainly due to excessive moisture or reused instantaneous glue. Fresh instantaneous glue should be ensured. Pipelines should be thoroughly cleaned with non-humid Aceton acetone. The air used should be determined to be dry and filters should be installed between the plant air pressure and the rubber valve system. (If the above methods are still ineffective, nitrogen should be used.) 。
