不锈钢阀门应用领域以及市场前景

不锈钢阀门因其使用寿命长、不易生锈、绿色环保等*优势已经走进工业应用当中，已成为各行业管道领域必采购的阀门产品。

Stainless steel valves have entered the industrial application because of their long service life, rusty and green environmental protection. They have become the valve products that must be purchased in all sectors of the pipeline industry.

不锈钢阀门通常应用于工作介质具有一定腐蚀性的场合，如腐蚀性介质、食品、药品、油品、液态金属和放射性介质等化工产品，在这些领域任何一种阀用材料，耐工作介质腐蚀的能力都是相对有限的，并受到许多因素的影响。如果在制造过程中采用的加工工艺与热处理工艺得当，进而保证这种材料的耐腐蚀性能。至于在浓度>98%的浓硝酸介质中，无论采用什么样的热处理工艺，这种钢材都不具有耐腐蚀性能。因此，在根据工作介质的性质来选用阀门材料时，必须同时研究介质的浓度、温度以及材料的热处理工艺等诸因素对耐腐蚀性能的影响，以选择更好的钢料如316或者特氟龙涂层阀门。

Stainless steel valves are usually used for work with certain corrosive media occasions, such as corrosive medium, food, medicine, oil, metals and radioactive liquid media and other chemical products in these areas, any kind of valve materials, the ability of resistance to corrosion of the working medium is relatively limited, and is affected by many factors. If the processing technology and heat treatment process are used properly in the manufacturing process, the corrosion resistance of the material is ensured. As for the concentrated nitric acid medium with a concentration of >98%, no matter what kind of heat treatment is used, this kind of steel has no corrosion resistance. Therefore, in the selection of valve materials according to the nature of media work, factors must study media concentration, temperature and material of the heat treatment on the corrosion resistance of steel material, in order to choose the better such as 316 or Teflon coated valves.

随着石油化工业技术和规模的不断发展，对石化用不锈钢阀门的要求越来越高，除了继续提高常规阀门的质量，特别是对腐蚀性物料的不锈钢阀需求量越来越大，因此要努力开发耐腐蚀的技术，316不锈钢阀门具有耐腐蚀，高强度，轻便，使用寿命长等优异特征。

With the continuous development of oil industry and the scale of petrochemical technology, stainless steel valves have become increasingly demanding, in addition to continue to improve the quality of conventional valve, especially stainless steel valve demand for corrosive material is bigger, so strive to develop corrosion technology, 316 stainless steel valve has corrosion resistance, high strength. Light, long life and other excellent features.

社会在进步行业在增多，对于能够使用不锈钢阀门产品的行业也在增多，新的行业新的产品且也将慢慢取代铸铁或者铝阀，这就为不锈钢阀门产业带来新机遇，市场发展前景良好，不锈钢阀门已成为各行业领域必采购的阀门产品。

The society is in progress in the industry increased, to use stainless steel valve products also increased, new products and new industries will gradually replace cast iron or aluminum valve, which will bring new opportunities for the industry of stainless steel valves, stainless steel valves good market prospects, has become the industry field will purchase valve products.

闸门主要由三部分组成:

①主体活动部分，用以封闭或开放孔口，通称闸门，亦称门叶；

②埋固部分；

③起闭设备。

钢制闸门产品特点：重量轻，效果好，使用方便省力。

耐腐蚀:耐酸碱及耐大部分腐蚀性化学品及污水、海水等。

密封性好:采用橡胶软密封，密封效果好

力矩小:由于闸板重量轻，且闸板与道轨板之间摩擦阻力小，故操作力矩小。

寿命长:闸板与导轨之间装有防锁死结构使密封面磨损非常小。

维修方便:若经多年使用后出现泄漏现象，只需将闸板吊起，调换门框上橡胶密封圈即可，省时省力，维修成本低。

手动操作:采用螺杆式启闭操作，操作方便、轻巧、可靠。

电动操作:电动控制装置，操作轻巧、易实现自控和远控。

按钢制闸门启闭力计算方法计算。可采用电动单梁吊车（电动葫芦、手动葫芦）配抓落机构启闭。宽度在1.5m以内，且深度合适时，可采用手提操作。

动水启闭力（如放水闸门，事故闸门），启闭力按铸铁闸门启闭计算。

静水启闭力（当闸门检修，设有旁路放水系统）时，启闭力为门体自重，闭门力不考虑。

大型钢制闸门承受水压较大时，为降低启闭力，可在闸门上设放水阀（水位平衡装置），在打开闸门前先平衡两侧水位，此型在订货时应注明，其启闭力同上述。
