弹性座封闸阀The elastic valve seat seal
  Resilient seated gate valve is a gate opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. Dark bar elastic valve seat seal with the valve plastic deformation the overall compensation package to achieve a good seal, valve seal to overcome the generally poor, Water Leakage and rusty phenomenon, saving installation space more effectively. Elastic seat sealing soft sealing gate valve can be widely used for fluid pipelines of tap water, sewage, construction, petroleum, chemical industry, food, pharmaceutical, textile, electric power, shipbuilding, metallurgy, energy system as a regulator and the closure device.

应用范围：弹性座封闸阀特别适用于生活饮用水系统、食品医药行业、工业给排水及污水处理、天燃气与煤气等，软密封闸阀也可广泛用于自来水、污水、建筑、石油、化工、食品、医药、轻纺、电力、船舶、治金、能源系统等流体管线上。

Scope of application: flexible seat seal gate valve is especially suitable for drinking water system, food and pharmaceutical industry, industrial water supply and sewage treatment, natural gas and coal gas, soft sealing gate valve can be widely used for fluid pipelines of tap water, sewage, construction, petroleum, chemical industry, food, pharmaceutical, textile, electric power, shipbuilding, metallurgy, energy system and so on.

结构特点：平底式阀座永嘉阀门供应网公司软密封闸阀底部采用全流域直通式流道设计，等同于直管道，无滞流凹腔结构，流阻小，确保流体畅通，不易沉积杂物，也不会对介质造成二次污染。

Structure features: flat style seat Yongjia valve supply network company soft sealing gate valve at the bottom of the use of the whole basin straight channel design, equivalent to the straight pipe, no stagnant cavity structure, small flow resistance, to ensure that the fluid flow is not easy to deposit, debris, will not cause secondary pollution to the media two.

全包覆闸板闸板采用球铁QT500-7骨架整体包覆高性能橡胶，成熟的硫化技术和先进的硫化工艺，彻底将闸板铁芯与流体隔离。包覆紧密可靠，其结合强度符合DVGW要求，即使受到频繁的挤压应力橡胶也不会脱落。阀杆螺母与闸板两体式结构，保证足够自由度，启闭灵活并无卡阻现象。

Fully coated gate gate made of ductile iron QT500-7 framework covering high performance rubber, vulcanized mature technology and advanced vulcanization process, complete the gate core and fluid isolation. Coating is compact and reliable, its combination of strength meet the requirements of DVGW, even by the frequent extrusion stress rubber does not drop. The valve stem nut and the two type structure, ensure sufficient freedom, flexible opening and closing no jamming.
