概述 弹性座封闸阀采用特种橡胶全包裹整体式弹性阀瓣，可在压力下产生微量的弹性变形，利用其与闸座的自适应性补偿作用，达到良好的密封效果。克服了它们传统闸阀密封不良，内件阀瓣易锈蚀，橡胶弹性疲乏易老化，且操作费力，维修不便等缺陷。可广泛用于洪水、石化、冶金、船舶、食品医药及能源系统等流体管路上作为调节和截流装置使用。 |
Overview Flexible seat seal gate valve is fully wrapped by special rubber.Pro-vided with integral flexible valve core,it is away from water leakage or rusting compared with ordinary gate valve,and the ubiquitous problems of bad seal,elasticity fat igue,aging of ruber and abrasion and rusting of sealing surface.lt makes full u se of the compensation function of micro distortion produced by flexible seal to actualize good sealing effect.This valve is widely used in fluid pipeline in the fields of water supply,petrochemicals,metallurgy,shipping,foodstuff, pharmaceuticals and en-ergy sources,functioned to adjust and cut off flow.

特点 1、整体包胶：阀芯采用高性能橡胶和最新的硫化技术进行整体包裹，贴合紧密牢固，几何尺寸精确，密封可靠，使用寿命长，操作轻快，维修简单便利。 2、重量轻：阀体球墨铸铁材料，重量较一般闸阀减轻25%，安装维修方便；阀门最大打开高度较一般闸阀低60mm~280mm，可安装有空间限制的场合。 3、平底式阀座：底部采用与管道相同的平底式阀座设计，不会产生杂物堆积，流道畅通无阻且密封可靠。 4、耐蚀性能：阀门内腔采用无毒环氧树脂粉末途装，内件采铜合金和不锈钢可防止腐蚀和生锈，不但可用于饮水、食品等系统，而且可用于污水或地下等系统中。 5、三“O”密封：阀杆上密封处采用O型圈密封，摩擦阻力小，开关轻巧不漏水。 |
Features Fully Rubber Wrapped:valve core fully wrapped by high perfor-mance rubber and latest vulcanization technology closely and firmly to effect accurate geometrical dimensions,dependable seal and long ser-vice life. Lightweight:valve gody made of spheroidal graphite cast iron mate-rial,25% lighter compared with ordinary gate valve,easy installation and servicing;maximum opening height 60mm~280mm lower than or-dinary gate valves,they may be mounted in spacerestricted locations. Flat-bottomed Valve Seat:design of flat-bottomed valve seat,which is the same as that of pipeline,will not result in sundries deposited,thus to effect smooth flow channel and reliable seal. Corrosion-resisting Performance:the chamber of valve is coated by nontoxic epoxy resin powder,and the internal parts are made of copper alloy and stainless steel to avoid corrosion and rusting.This product is not only applicable for drinking water and foodstuff system,but also applicable for sewage and underground system.
３＂Ｏ＂Seals:The upper seal of valve stem uses O-ring for small abra-sion resistance,handy open-close and leak-tightness. |
