| 目的 研发一种适合灌装腐蚀性溶液的灌装阀。 方法 打破金属灌装阀的传统设计理念,塑料灌装阀以高分子塑料为主体结构,利用塑料阀杆柔韧、 抗拉的特点, 当阀杆被向上拉起时, 灌装阀关闭,同时阀杆下端的阀芯和导向阀体形成线性密封;当阀杆被推动下移时,灌装阀打开。 另外灌装阀设置了弹簧,用于保障气路故障时灌装阀仍处于关闭状态,避免泄漏。 结果 塑料灌装阀不但能够抵抗强酸、强碱等液体的腐蚀,而且具有结构合理、安全可靠、成本低等优点。 结论 塑料灌装阀成功地解决了化工领域腐蚀性溶液灌装的难题。 |

| Objective To invent a filling valve for filling corrosive solution. Methods Breaking the traditional design concept of metal filling valve, plastic filling valve used polymer plastic as its main structure material, which utilized the flexible and tensile characteristics of plastic valve-stem. When the valve-stem was pulled up , the filling valve was closed. Simultaneously, at the end of the valve-stem the valve core and guiding valve-body formed hermetical loop-line. When the valve-stem was pushed down, the filling valve was opened. In addition, a spring was installed on top of the filling valve to ensure that the valve stay close in case of gas path fault, to avoid liquid leakage. Results Plastic filling valve was not only corrosion resistant to strong acid and strong alkali but also had many other merits such as reasonable structure, higher security, higher reliability and lower manufacturing cost. Conclusion Plastic filling valve successfully solved the problem of filling corrosive liquid in the field of chemical industry. |
