不锈钢球阀厂家为您详细分析：铜球阀和不锈钢球阀的区别在哪里？
The stainless steel ball valve manufacturer makes a detailed analysis for you: What is the difference between copper ball valve and stainless steel ball valve?
铜球阀和不锈钢球阀有一下五点区别：
There are five differences between copper ball valve and stainless steel ball valve:
1、材质不同：它们采用的材质完全不同，铜球阀采用的材料主要以铜组成。，不锈钢球阀采用的是不锈钢。
1. Different materials: they are made of completely different materials. The copper ball valve is mainly made of copper., Stainless steel ball valve is made of stainless steel.
2、耐腐蚀性不同：铜球阀耐腐蚀性比不锈钢球阀好，开关操作顺畅省力，耐久不漏。不锈钢不会产生腐蚀、点蚀、锈蚀或磨损以及耐高温。一般不锈钢的贵点了。
2. Different corrosion resistance: the corrosion resistance of copper ball valve is better than that of stainless steel ball valve. The switch operation is smooth, labor-saving and durable. Stainless steel will not produce corrosion, pitting, rust or wear and is resistant to high temperatures. Generally, stainless steel is more expensive.
3、温度不同：按相同压力环境下，如果介质温度不超过80度，则用不锈钢球阀就可以了，如果温度超过80度则必需要用铜球阀。
3. Different temperatures: under the same pressure environment, if the medium temperature does not exceed 80 degrees, stainless steel ball valves can be used; if the temperature exceeds 80 degrees, copper ball valves must be used.
4、不同：铜球阀造价材料比较贵，不锈钢球阀造价材料比铜球阀便宜。
4. Price difference: copper ball valve is more expensive, while stainless steel ball valve is cheaper than copper ball valve.
5、适用物质不同：不锈钢球阀可用于控制空气、水、蒸汽、各种腐蚀性介质、泥浆、油品、液态金和放射性介质等各种类型流体的流动；铜球阀适用于水、溶剂、酸和天然气等一般工作介质，而且还适用于工作条件恶劣的介质，如氧气、过氧化氢、甲烷和乙烯等。
5. Applicable substances are different: stainless steel ball valves can be used to control the flow of air, water, steam, various corrosive media, mud, oil, liquid gold, radioactive media and other types of fluids; Copper ball valves are suitable for general working media such as water, solvent, acid and natural gas, and also for media with poor working conditions, such as oxygen, hydrogen peroxide, methane and ethylene.
不锈钢球阀
Stainless steel ball valve
不锈钢球阀只需要用旋转90度的操作和很小的转动力矩就能关闭严密。完全平等的阀体内腔为介质提供了阻力很小、直通的流道。球阀的主要特点是本身结构紧凑，易于操作和维修，不锈钢球阀可用于控制空气、水、蒸汽、各种腐蚀性介质、泥浆、油品、液态金属和放射性介质等各种类型流体的流动。球阀阀体可以是整体的，也可以是组合式的。本类阀门在管道中一般应当水平安装。
