        具有国内领先水平的、石化行业催化装置关键国产化特种阀门——超高温快速液动蝶阀，最近在浙江石化阀门有限公司自主研发成功，电磁阀并获得了国家2项发明专利和2项实用新型专利。 据该公司总工程师李保升介绍，超高温快速液动蝶阀是催化装置的关键国产化特种阀门，其使用工况和制造难度远超于普通阀门，隔膜阀多年来一直依赖进口。国内也有几家阀门厂试图开发该产品，疏水阀但他们采用三偏心结构，无法克服蝶板由于高温热膨胀而产生的卡阻现象，存在安全隐患，均以失败告终。

 为此，浙江石化阀门公司经过反复研究和多次试验，旋塞阀终于研制成功。该产品的主要创新点有：一是五连杆偏摆传动机构，二是快速关闭功能设计，三是流量调节精度的保证，并合理选材，不仅结构新颖独特，而且经济适用。柱塞阀经全国20多家大型石化企业应用，效果良好，前景广阔。

          With the leading domestic level, the petrochemical industry, the key catalytic device made of special valves - ultra high speed fluid moving butterfly, Zhejiang Petrochemical Valve Co., Ltd. recently independently developed and received two national invention patents and two Instrumentation Ball Valves practical new patent. According to the company's chief engineer Safety Relief Valves Li Bao-sheng introduced ultra-high speed hydraulic valve is the key catalytic device made of special valves, the use of conditions and difficult to manufacture far more than in the ordinary valve, has been imported. There areNeedle & Gauge Valves also a few attempts to develop the product valve factory, they use three eccentric structure, can not overcome the butterfly plate Youyu high temperature thermal expansion of the card produced the phenomenon of resistance, there is potential safety problems, failed. To this end, Zhejiang PetrochemicalInstrument Manifolds Valve Company after repeated research and numerous experiments, and finally developed. The main innovation of the product are: First, the swing transmission five-link, the second is theBalance Valves rapid shut-down design, the three flow control accuracy is guaranteed, and a reasonable selection, new and unique in structure, but also affordable. The country more than 20 large petrochemical enterprise applications, good results, prospects are bright.
