特点

Characteristics

1、防尘圈加三道“O”型密封圈设计，密封可靠，可在线更换。

2、闸板与铝青铜轴承为镶嵌设计，自润滑好、强度高，可在长久使用易损更换铝青铜轴承，无需整体更换闸板。

3、闸板包胶、耐腐蚀、密封性好。

4、表面处理先进，采用无害环氧树脂静电粉末涂装，耐腐蚀，无污染，可用于饮水管路。

5、阀体采用无闸槽设计，通道平滑，不会造成杂物淤积，更适用于污水工况。

6、整体密封可靠，高压密封在1.5倍公称压力，低压密封0.02MPa下零泄漏。

1.The seal is designed with dustproof ring plus three "O"-seal rings, reliable sealing, on-line replaceable.

2.Both gate and aluminum bronze bearing are in inlaid design, good self ubrication, high strength and can have the aluminum bronzebearing replaced without need to replace the gate integrally, after a long time use.

3.Rubber wrapped gate, anti-corrosion, good tightness.

4.Advanced surface treatment, coated with non-toxic epoxy resign static powder, anti-corrosion, pollution-free, can be used drinkingwater pipeline.

5.The body is designed without gate slot, the smooth passage will not get impurities filing up, more applicable for sewage working condition.

6.The integral seal works reliably.For the high pressure seal, leaving zero leakage under 1.5 times nominal pressure and, for the low

pressure one, under 0.02MPa.
