据我市采用浙江省玉坏防腐阀门厂生产的YH柱塞阀门的企业反映,该阀门防漏、节能效果良好。我们对该厂的情况和产品进行了考查。 浙江省玉坏防腐阀门厂引进国外技术,结合国内情况加以改进,设计了YH柱塞式阀门,已形成了公称直径15～200mm,压力1.6、2.5、4.0MPa的系列产品。阀门的结构长度、法兰连接尺寸、公称直径与公称压力均按JB792-65部标。合肥通用机械研究所对阀门进行了寿命试验并提出了报告,开启次数试至3600-3680次(JB792-65规定为3000次)渗漏均为零。此产品获得了浙江省计经委、省对外经济贸易厅和省进出口商品检验局联合颁发的“浙江省出口商品质量保证企业合格证”。
According to the city of Zhejiang Yalu anti-corrosion valve factory production YH plunger valve business reflects the valve leak-proof, energy-saving effect is good. We examined the condition of the plant and the product. Zhejiang Yu-bad anti-corrosion valve factory introduction of foreign technology, combined with domestic conditions to be improved, designed YH plunger valve, has formed a nominal diameter of 15 ~ 200mm, pressure 1.6,2.5,4.0 MPa series. Valve structure length, flange connection size, nominal diameter and nominal pressure according to JB792-65 department standard. Hefei General Machinery Research Institute of the valve life test and made a report, the number of open trials to 3600-3680 times (JB792-65 provisions of 3000) leakage are zero. This product won the Zhejiang Provincial Economic Commission, the Provincial Department of Foreign Trade and Economic Cooperation and the Provincial Import and Export Commodity Inspection Bureau jointly issued the “Zhejiang Province export commodities quality assurance business certification.”
