高溫閥門(mén)依靠介質(zhì)自身的壓力自動(dòng)開(kāi)啟閥門(mén),高溫閥門(mén)迅速排出一定數(shù)量的介質(zhì).高溫閥門(mén)當(dāng)容器內(nèi)的壓力降到允許值時(shí),高溫安全閥又自動(dòng)關(guān)閉,高溫安全閥使容器內(nèi)壓力始終低于允許壓力的上限,高溫閥門(mén)自動(dòng)防止因超壓而可能出現(xiàn)的事故,高溫閥門(mén)又被稱(chēng)為壓力容器的保護(hù)裝置.
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、高溫閥門(mén)材料
1. High temperature valve material
一般我們將工作溫度大于450攝氏度的閥門(mén)成為高溫閥門(mén).一般將工作溫度大于450攝氏度的閥門(mén)材料,稱(chēng)為高溫閥門(mén)材料.常見(jiàn)的高溫閥門(mén)材料有:ZG1Cr18Ni9Ti、Cr-Ni耐熱合金、CF8Ti(321)、CF10Ti(321H)、Cr-Mo系鑄鋼、CF8M、CK-20、ZG0Cr19Ni11Ti、CF3、CF3M、CF8、HK-30、HK-40、304、304H、WC6(介質(zhì)是水或蒸汽)、WC9(介質(zhì)是水或蒸汽)、C5(ZG1Cr5Mo)、310高鉻鎳不銹耐熱鋼、310H高鉻鎳不銹耐熱鋼等.
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、高壓閥門(mén)材料
2. High pressure valve material
那壓力超過(guò)多少就可以叫做高壓閥門(mén)呢?在閥門(mén)行業(yè)有一個(gè)基本的共識(shí),那就是壓力在10MPa到80MPa之間稱(chēng)作高壓閥門(mén).常見(jiàn)的高壓閥門(mén)材料有:碳鋼A105/WCB、1Cr13、2Cr13、3Cr13鉻不銹鋼、不銹鋼304、Cr18Ni12Mo2Ti、316、WC6、WC9、15CrMoG/15CrMoV、321、ZG15Gr1Mo1V、ZG20CrMoV、347、40Cr(鉻鋼)、1Cr5M0、F51、ZGCr5Mo、Cr17Ni2、F91、CF8、鉻鉬鋼、CF3、1Cr18Ni9Ti、12CrMoV、CF8M、PH15-7Mo沉淀硬化鋼、CF3M、Cr18Ni12Mo3Ti、合金鋼F5、F11、F22、低溫鋼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
