閥門應(yīng)用場所及調(diào)控數(shù)據(jù)你知道多少?

  使用場合:

  Usage scenario:

  閥門廣泛應(yīng)用于流體輸送系統(tǒng)中,用于控制空氣、水、蒸汽、各種腐蝕性介質(zhì)、泥漿、油品、液態(tài)金屬和放射性介質(zhì)等各種類型流體的流動。

  Valves are widely used in fluid transportation systems to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metals, and radioactive media.

  具體應(yīng)用包括但不限于截斷類(如閘閥、截止閥等)、止回類(用于阻止介質(zhì)倒流)、調(diào)節(jié)類(調(diào)節(jié)介質(zhì)的壓力和流量)、安全類(在介質(zhì)壓力超過規(guī)定值時排放多余的介質(zhì))以及分配類(改變介質(zhì)流向)等。

  Specific applications include but are not limited to shut-off valves (such as gate valves, globe valves, etc.), check valves (used to prevent medium backflow), regulating valves (regulating the pressure and flow rate of the medium), safety valves (discharging excess medium when the medium pressure exceeds the specified value), and distribution valves (changing the flow direction of the medium).

  高壓安全閥廣泛適用于石油、化工、電力、冶金、航空等各個領(lǐng)域的高壓設(shè)備中,如鍋爐、壓縮機、管道、容器等,保護設(shè)備免受過壓,防止發(fā)生爆炸等危險事故。

  High pressure safety valves are widely used in high-pressure equipment in various fields such as petroleum, chemical, power, metallurgy, aviation, etc., such as boilers, compressors, pipelines, containers, etc., to protect equipment from overpressure and prevent dangerous accidents such as explosions.

  閥門的選擇不僅基于其壓力范圍,還考慮工作溫度、介質(zhì)特性以及特定的工業(yè)應(yīng)用要求。例如,高溫閥工作溫度≥450℃,中溫閥120℃≤工作溫度<450℃,常溫閥-40℃≤工作溫度<120℃,低溫閥-100℃≤工作溫度<40℃,超低溫閥工作溫度<-100℃。此外,閥門的材質(zhì)也是選擇的關(guān)鍵因素,包括鑄鐵、鑄鋼、不銹鋼(201、304、316等)、鉻鉬鋼、鉻鉬釩鋼、雙相鋼、塑料等。

  The selection of valves is not only based on their pressure range, but also takes into account working temperature, medium characteristics, and specific industrial application requirements. For example, high-temperature valves have a working temperature of ≥ 450 ℃, medium temperature valves have a working temperature of 120 ℃ ≤<450 ℃, normal temperature valves have a working temperature of -40 ℃ ≤<120 ℃, low-temperature valves have a working temperature of -100 ℃ ≤<40 ℃, and ultra-low temperature valves have a working temperature of<-100 ℃. In addition, the material of the valve is also a key factor in the selection, including cast iron, cast steel, stainless steel (201, 304, 316, etc.), chromium molybdenum steel, chromium molybdenum vanadium steel, duplex steel, plastic, etc.
