The high-temperature valve automatically opens the valve based on the pressure of the medium itself, and quickly discharges a certain amount of medium. When the pressure inside the container drops to the allowable value, the high-temperature safety valve automatically closes. The high-temperature safety valve keeps the pressure inside the container below the upper limit of the allowable pressure, and the high-temperature valve automatically prevents accidents that may occur due to overpressure. The high-temperature valve is also known as the protective device of the pressure vessel

1、高温阀门材料

1. High temperature valve material

一般我们将工作温度大于450摄氏度的阀门成为高温阀门.一般将工作温度大于450摄氏度的阀门材料,称为高温阀门材料.常见的高温阀门材料有:ZG1Cr18Ni9Ti、Cr-Ni耐热合金、CF8Ti(321)、CF10Ti(321H)、Cr-Mo系铸钢、CF8M、CK-20、ZG0Cr19Ni11Ti、CF3、CF3M、CF8、HK-30、HK-40、304、304H、WC6(介质是水或蒸汽)、WC9(介质是水或蒸汽)、C5(ZG1Cr5Mo)、310高铬镍不锈耐热钢、310H高铬镍不锈耐热钢等.

Generally, valves with operating temperatures greater than 450 degrees Celsius are referred to as high-temperature valve materials. Common high-temperature valve materials include ZG1Cr18Ni9Ti, Cr Ni heat-resistant alloy, CF8Ti (321), CF10Ti (321H), Cr Mo cast steel, CF8M, CK-20, ZG0Cr19Ni11Ti, CF3, CF3M, CF8, HK-30, HK-40, 304, 304H, WC6 (medium is water or steam), WC9 (medium is water or steam) C5 (ZG1Cr5Mo), 310 high chromium nickel stainless and heat-resistant steel, 310H high chromium nickel stainless and heat-resistant steel, etc

2、高压阀门材料

2. High pressure valve material

那压力超过多少就可以叫做高压阀门呢?在阀门行业有一个基本的共识,那就是压力在10MPa到80MPa之间称作高压阀门.常见的高压阀门材料有:碳钢A105/WCB、1Cr13、2Cr13、3Cr13铬不锈钢、不锈钢304、Cr18Ni12Mo2Ti、316、WC6、WC9、15CrMoG/15CrMoV、321、ZG15Gr1Mo1V、ZG20CrMoV、347、40Cr(铬钢)、1Cr5M0、F51、ZGCr5Mo、Cr17Ni2、F91、CF8、铬钼钢、CF3、1Cr18Ni9Ti、12CrMoV、CF8M、PH15-7Mo沉淀硬化钢、CF3M、Cr18Ni12Mo3Ti、合金钢F5、F11、F22、低温钢LF2、LF3、LCB等.

How much pressure can it be called a high-pressure valve? There is a basic consensus in the valve industry that the pressure range is between 10MPa and 80MPa, which is called a high-pressure valve. Common high-pressure valve materials include: carbon steel A105/WCB, 1Cr13, 2Cr13, 3Cr13 chromium stainless steel, stainless steel 304, Cr18Ni12Mo2Ti, 316, WC6, WC9, 15CrMoG/15CrMoV, 321, ZG15Gr1Mo1V, ZG20CrMoV, 347, 40Cr (chromium steel), 1Cr5M0, F51, ZGCr5Mo, Cr17Ni2, F91, CF8, chromium molybdenum steel, CF3, 1Cr18 Ni9Ti, 12CrMoV, CF8M PH15-7Mo precipitation hardening steel, CF3M, Cr18Ni12Mo3Ti, alloy steel F5, F11, F22, low-temperature steel LF2, LF3, LCB, etc
