A41Y、A42Y、A44Y不銹鋼安全閥產品描述：
不銹鋼安全閥是受壓設備、容器或管路上的佳超壓保護裝置。當設備壓力升高達到預定值時，安全閥自動開啟，繼而全量排放，防止設備壓力繼續升高；當壓力降低到規定值時，安全閥及時自動關閉。A41Y、A42Y、A44Y不銹鋼安全閥是選用者為保護工程設備安全運行的理想的，科學的明智選擇。

A41Y、A42Y、A44Y不銹鋼安全閥閥門快訊：
〖冷凍機安全閥〗〖微啟式安全閥〗〖全啟式安全閥〗〖杠桿式安全閥〗〖先導式安全閥〗 〖脈沖式安全閥〗〖內裝式安全閥〗〖彈簧式安全閥〗〖主安全閥〗〖空壓機安全閥〗〖真空安全閥〗〖氧汽用安全閥〗〖鍋爐用安全閥〗〖安全益流閥〗〖安全回流閥〗〖防爆波安全閥〗〖高壓安全閥〗〖抗硫安全閥〗〖螺紋安全閥〗〖法蘭安全閥〗〖焊接安全閥〗〖雙聯式安全閥〗
安全閥是啟閉件受外力作用下處于常閉狀態，當設備或管道內的介質壓力升高超過規定值時，通過向系統外排放介質來防止管道或設備內介質壓力超過規定數值的特殊閥門。安全閥屬于自動閥類，主要用于鍋爐、壓力容器和管道上，控制壓力不超過規定值，對人身安全和設備運行起重要保護作用。注安全閥必須經過壓力試驗才能使用。
安全閥在系統中起安全保護作用。當系統壓力超過規定值時，安全閥打開，將系統中的一部分氣體/流體排入大氣/管道外，使系統壓力不超過允許值，從而保證系統不因壓力過高而發生事故。
公稱壓力：表示安全閥在常溫狀態下的高許用壓力，高溫設備用的安全閥不應考慮高溫下材料許用應力的降低。安全閥是按公稱壓力標準進行設計制造的。
開啟壓力：也叫額定壓力或整定壓力，是指安全閥閥瓣在運行條件下開始升起時的進口壓力，在該壓力下，開始有可測量的開啟高度，介質呈可由視覺或聽覺感知的連續排放態。
排放壓力：閥瓣達到規定開啟高度時的進口壓力。排放壓力的上限需服從國家有關標準或規范的要求。
超過壓力：排放壓力與開啟壓力之差，通常用開啟壓力的百分數來表示。
回座壓力：排放后閥瓣重新與閥座接觸，即開啟高度變為零時的進口壓力。
啟閉壓差：開啟壓力與回座壓力之差，通常用回座壓力與開啟壓力的百分比表示，只有當開啟壓力很低時采用二者壓力差來表示。
背壓力：安全閥出口處的壓力。
額定排放壓力：標準規定排放壓力的上限值。
密封試驗壓力：進行密封試驗的進口壓力，在該壓力下測量通過關閉件密封面的泄漏率。
開啟高度：閥瓣離開關閉位置的實際升程。
流道面積：指閥瓣進口端到關閉件密封面間流道的小截面積，用來計算無任何阻力影響時的理論排量。
流道直徑：對應用于流道面積的直徑。
簾面積：當閥瓣在閥座上方時，在其密封面之間形成的圓柱面形或圓錐面形通道面積。
排放面積：閥門排放時流體通道的小截面積。對于全啟示安全閥，排放面積等于流道面積；對于微啟式安全閥，排放面積等于簾面積。
理論排量：是流道截面積與安全閥流道面積相等的理想噴管的計算排量。
排量系數：實際排量與理論排量的比值。
額定排量系數：排量系數與減低系數（取0.9）的乘積。
額定排量：指實際排量中允許作為安全閥適用基準的那一部分。
當量計算排量：指壓力、溫度、介質性質等條件與額定排量的適用條件相同時，安全閥的計算排量。
頻跳：安全閥閥瓣迅速異常地來回運動，在運動中閥瓣接觸閥座。
顫振：安全閥閥瓣迅速異常地來回運動，在運動中閥瓣不接觸閥座。
安全閥結構主要有兩大類：彈簧式和杠桿式。彈簧式是指閥瓣與閥座的密封靠彈簧的作用力。杠桿式是靠杠桿和重錘的作用力。隨著大容量的需要，又有一種脈沖式安全閥，也稱為先導式安全閥，由主安全閥和輔助閥組成。當管道內介質壓力超過規定壓力值時，輔助閥先開啟，介質沿著導管進入主安全閥，并將主安全閥打開，使增高的介質壓力降低。
安全閥的排放量決定于閥座的口徑與閥瓣的開啟高度，也可分為兩種：微啟式開啟高度是閥座內徑的（1/20）～（1/40），全啟式是（1/3）～（1/4）。
