產(chǎn)品詳情

用途Purpose

本閥門安裝于各種管路上,作為雙向閉路設(shè)備使用。廣泛應(yīng)用于自來水、污水處理、冶金石油、建筑、化工、電力等行業(yè)。

This valve is mounted on various pipelines and used as a dual-way closed instalaion for tap water, sewage treatment, metallurgy, petroleum,construction, chemical, electric power etc. trades.

 

特點

Characteristics

1、防塵圈加三道“O”型密封圈設(shè)計,密封可靠,可在線更換。

2、閘板與鋁青銅軸承為鑲嵌設(shè)計,自潤滑好、強度高,可在長久使用易損更換鋁青銅軸承,無需整體更換閘板。

3、閘板包膠、耐腐蝕、密封性好。

4、表面處理先進(jìn),采用無害環(huán)氧樹脂靜電粉末涂裝,耐腐蝕,無污染,可用于飲水管路。

5、閥體采用無閘槽設(shè)計,通道平滑,不會造成雜物淤積,更適用于污水工況。

6、整體密封可靠,高壓密封在1.5倍公稱壓力,低壓密封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.
