弹性座封闸阀
Elastic seat seal gate valve
特点
• 重量轻：本体采用高级球墨铸铁制成，重量较传统闸阀重量减轻20%-30%,安装维修方便。
• 平底式闸座：传统的闸阀往往在通水洗管后即因外物诸如石头、木块、水泥、铁屑、杂物等淤积于阀底凹槽内，容易造成无法关闭紧密而形成漏水现象，弹性座封闸阀底部采用与水管机同的平底设计，不易造成杂物淤积，使流体畅通无阻。
• 整体包胶：闸板采用高品质的橡胶进行整体内、外包胶欧洲一流的橡胶硫化技术使得硫化后的闸板能够保证精确的几何尺寸且橡胶与墨球铸闸板接着牢靠，不易脱落及弹性记忆佳。
• 精铸阀体：阀体采用精密铸造，精确的几何尺寸使得阀体内部无需任何精加工，即可保证阀门的密封性。
• 嵌入式铜螺母：铜螺母与弹性闸板采用嵌入式接合，使二者紧密结合成为一体，不因水流动造成震动而产生松动或损坏现象。
• 耐腐蚀：阀体采用粉体环氧树脂涂装，可防止阔体的腐蚀及生锈，并可用于污水系统。
• 不易碎裂：以往传统铸铁闸阀常因外物击中，碰撞或重压而造成断裂等现象。由于本体改用球墨铸铁，此种情形已可大幅度减少。
• 三“O”型环密封圈：由于阀杆采用三“O”型环密封圈密封设计，可减少关闭时的摩擦阻力，大幅减少漏水现象及可以不停水施工更换密封圈。
• 有助生饮：由于阀体内部以无毒性环氧树脂涂装，阀门的内外表面均以橡胶完全披覆而不至于出现生锈或腐蚀现象可供生饮。
peculiarity
• Light weight: the body is made of high-grade ductile iron, the weight is 20%-30% less than the traditional gate valve weight, easy to install and maintain.
• Flat-bottom gate seat: The traditional gate valve often accumulates in the bottom groove of the valve due to foreign objects such as stones, wood blocks, cement, iron debris, debris, etc., which is easy to cause water leakage phenomenon, and the bottom of the elastic seat sealing gate valve is designed with the flat bottom of the pipe machine, which is not easy to cause debris deposition, so that the fluid is unimpeded.
• Integral coating: The ram uses high-quality rubber for integral internal and external rubber Europe's first-class rubber vulcanization technology enables the vulcanized ram to ensure accurate geometric size and rubber and ink ball cast ram to be reliable, not easy to fall off and good elastic memory.
• Precision casting valve body: The valve body adopts precision casting, the precise geometry makes the valve body without any finishing inside, which can ensure the sealing of the valve.
• Embedded copper nut: Copper nut and elastic ram adopt embedded joint, so that the two are closely integrated into one, and do not loose or damage due to vibration caused by water flow.
• Corrosion resistance: The valve body is coated with powder epoxy resin, which can prevent corrosion and rust of the broad body, and can be used in sewage systems.
• Not easy to break: in the past, traditional cast iron gate valves are often broken due to foreign objects hit, collision or heavy pressure. Due to the change of the body to ductile iron, this situation can be greatly reduced.
• Three "O" ring seal: Because the valve stem adopts three "O" ring seal seal design, it can reduce the friction resistance during closing, greatly reduce the leakage phenomenon and can replace the seal ring without stopping water construction.
• For drinking: Since the inside of the valve body is coated with non-toxic epoxy resin, the inner and outer surfaces of the valve are completely covered with rubber to avoid rust or corrosion.

Structural characteristics
For a long time, the general gate valve used in the market generally has water leakage or rust phenomenon. The elastic seat seal gate valve produced by the introduction of European high-tech rubber and valve manufacturing technology has overcome the defects of poor seal and rust of the general gate valve. The elastic seat seal gate valve uses the elastic disc to produce a small amount of elastic deformation compensation to achieve good sealing effect. The valve has the advantages of light switch, reliable seal, good elastic memory and long service life. It can be widely used in tap water, sewage, construction, petroleum, chemical industry, food, medicine, textile, electric power, shipbuilding, metallurgy, energy system and other fluid pipelines as regulating and intercepting devices.
