球墨铸铁井盖的特点

作者: -1    发布时间: 2018-06-15    次浏览

井盖是我们熟知的地面设备,它分布于街头的大街小巷、人行道、机动车道,只要有下水道就会有它的存在,它遮盖住道路的井口,以防行人或者物体不慎跌落进入井口,发生危险。井盖虽然不起眼,但是在道路上发挥着巨大的作用,所以井盖的设计也在不断进步。球墨铸铁井盖是井盖中的一种,它是球墨铸铁制作的一种新型井盖,相比较于传统井盖,具有以下几种优势:

Well cover is a well known ground equipment. It is distributed in streets, sidewalks, and motorized lanes in the streets. As long as there is a sewer, it will exist. It covers the wellhead of the road so as to prevent pedestrians or objects falling into the wellhead inadvertently. Although the well cover is unremarkable, it plays a huge role on the road, so the design of the well cover is also improving. The ductile iron manhole cover is one of the manhole covers. It is a new type of well cover made of ductile iron. Compared with the traditional manhole cover, it has the following advantages:


球墨铸铁井盖


1、韧性好 冲击值与中碳钢材详尽,是灰铁材料的10倍以上。

The toughness value is 10 times higher than that of medium carbon steel.

2、抗腐蚀性强 喷水腐蚀试验,九十天的腐蚀量仅为钢管的1/40,是灰铁管的1/10。使用寿命是灰铁管的2倍,是普通钢管的5倍。

The corrosion resistance of spray corrosion test, the corrosion amount of ninety days is only 1/40 of the steel pipe, 1/10 pipe is grey. Life is 2 times of gray iron, is 5 times of ordinary steel

3、塑性好 延伸率≥7/100,与高碳钢材相近,而灰铁材料延伸率为零。

The plastic elongation is more than or equal to 7/100, which is similar to that of high carbon steel, while the elongation of gray iron material is zero.

4、强度高 抗拉强度ób≥420MPa,屈服强度ós≥300MPa,与低碳钢材相同,是灰铁材料的三倍。墨铸铁的强度和铸钢的强度是可比的,球墨铸铁具有更高的屈服强度,其屈服强度最低为40k,而铸钢的屈服强度只有36k。在大部分市政应用领域,如:水、盐水、蒸汽等,球墨铸铁的耐腐蚀性和抗氧化性都超过铸钢,主要应用领域:市政道路,高速公路,通信,电力,自来水,小区,学校等各种园区。

The tensile strength is B higher than 420MPa, and the yield strength is more than s 300MPa, which is three times the same as that of low carbon steel. The strength of spheroidal graphite cast iron is comparable with the strength of cast steel. Spheroidal graphite cast iron has higher yield strength, its yield strength is lowest 40K, and the yield strength of cast steel is only 36K. In most of the municipal applications, such as water, brine, steam, and so on, the corrosion resistance and oxidation resistance of ductile iron exceed the cast steel. The main applications are municipal roads, freeways, communications, electricity, tap water, residential areas, schools and other parks.

5、较好的防盗与安全性能 球墨铸铁井盖篦子的抗拉强度及耐压性能与钢相似,因此又名铸钢。相比传统灰口铸铁其延伸率大大提高,具有良好的韧性,不易破坏,具有比普通铸铁井盖较好的防盗性能,整体性能更大大优于普通铸铁井盖。

Better anti-theft and safety performance. The tensile strength and pressure resistance of the grate of the ductile iron well cover are similar to those of steel, so it is also known as cast steel. Compared with the traditional gray cast iron, its elongation is greatly improved, it has good toughness, not easy to destroy, and has better anti-theft performance than ordinary cast iron well cover, and the overall performance is much better than that of ordinary cast iron well cover.

6、无噪音 由于采用防止噪音的专利构造,井盖过车时无声音,不再扰民。

No noise due to the use of noise prevention patent structure, the well cover when passing the car without noise, no nuisance.
