Valve Materials Technical Terms - English and Chinese Comparison
Ferrous Valves
铁质阀门
Cast Iron Valves
铸铁阀门
Cast iron is an alloy of iron and carbon, and is the original metal that was used for valves before other materials such as stainless steel became popular. Valves of this type may also have other materials added such as nickel, chromium and silicon. This type of valve is mainly used in medium pressure applications since it has a good combination of strength and corrosion resistance. Cast iron is available in a variety of grades and has superior machinability when compared to other ferrous materials.
铸铁是铁和碳的合金，在其他材料如不锈钢流行之前，它是用于阀门的原始金属。这种类型的阀门也可以添加其他材料，如镍，铬和硅。凭借其强度和耐腐蚀性的良好组合，该类阀门主要用于中压应用。铸铁可用于各种等级，并且与其他铁质材料相比具有优良的加工性能。
Ductile Iron Valves
球墨铸铁阀门
Ductile iron is also an alloy of iron and carbon, but contains a greater quantity of carbon, making it stronger and more wear-resistant than cast iron. This type of valve is suitable for high pressure applications, particularly because it is able to withstand greater levels of pressure, temperature, and vibration. It has superior corrosion resistance, and is often used in applications where other materials would wear away quickly due to its toughness and durability.
球墨铸铁也是铁和碳的合金，但含有更多的碳，使其比铸铁更强壮，更耐磨。该类阀门适用于高压应用，特别是因为它能够承受更高的压力，温度和振动。它具有优良的耐腐蚀性，并且常用于其他材料会快速磨损的应用，因为它的韧性和耐久性。
Steel Valves
钢质阀门
Steel is an alloy of iron, carbon and other elements and is the main type of material used in the construction of pipe valves today. Steel has good strength and corrosion resistance, but it is a relatively heavy material and is more prone to wear than other materials. This type of valve is suitable for medium to high pressure applications, but it is not recommended for very high pressure or temperature applications due to its high weight.
钢是铁，碳和其他元素的合金，是当今用于管道阀门结构的主要材料。钢具有良好的强度和耐腐蚀性，但它是一种相对较重的材料，比其他材料更容易磨损。该类阀门适用于中到高压应用，但由于其较高的重量，不建议用于非常高压或高温应用。
Stainless Steel Valves
不锈钢阀门
Stainless steel is an alloy of iron and chromium, and is one of the most common materials used in the construction of valves. Stainless steel has excellent corrosion resistance and is often used in applications where other materials would corrode quickly. This type of valve is suitable for high pressure and temperature applications, and is often used in applications that require the ability to withstand high levels of vibration.
不锈钢是铁和铬的合金，是用于阀门结构的最常用材料之一。不锈钢具有优异的耐腐蚀性，经常用于其他材料容易腐蚀的应用中。该类阀门适用于高压和高温应用，常用于需要承受高振动水平的应用中。
Brass Valves
黄铜阀门
Brass is an alloy of copper and zinc, and is a relatively low-cost material with good corrosion resistance. In addition to this, brass has good machinability and is often used for components and applications that require high levels of precision. This type of valve is used in a variety of low and medium pressure applications, and is often used in low temperature applications due to its good corrosion and wear resistance.
黄铜是铜和锌的合金，是一种相对低成本的材料，具有良好的耐腐蚀性。此外，黄铜具有良好的加工性能，经常用于需要高精度的零部件和应用中。该类阀门用于各种低压和中压应用，并且因其良好的耐腐蚀性和耐磨性经常用于低温应用中。
Non-Ferrous Valves
非铁质阀门
Aluminum Valves
铝阀门
Aluminum is a lightweight metal with good corrosion resistance and is often used in the construction of valves for low and medium pressure applications. This material is relatively easy to work with and can be machined into complex shapes. Aluminum is often used in low temperature applications due to its excellent thermal and electrical conductivity.
铝是一种轻量级金属，具有良好的耐腐蚀性，经常用于低压和中压应用的阀门结构中。该材料相对易于加工，可以机加工成复杂的形状。由于其优异的热传导性和电导性，铝经常用于低温应用中。
