安全閥在系統(tǒng)中起安全保護(hù)作用。當(dāng)系統(tǒng)壓力超過(guò)規(guī)定值時(shí)，安全閥打開(kāi)，將系統(tǒng)中的一部分氣體/流體排入大氣/管道外，使系統(tǒng)壓力不超過(guò)允許值，從而保證系統(tǒng)不因壓力過(guò)高而發(fā)生事故。


安全閥結(jié)構(gòu)主要有兩大類(lèi)：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(chēng)為先導(dǎo)式安全閥，由主安全閥和輔助閥組成。當(dāng)管道內(nèi)介質(zhì)壓力超過(guò)規(guī)定壓力值時(shí)，輔助閥先開(kāi)啟，介質(zhì)沿著導(dǎo)管進(jìn)入主安全閥，并將主安全閥打開(kāi)，使增高的介質(zhì)壓力降低。

按結(jié)構(gòu)分
按其整體結(jié)構(gòu)及加載機(jī)構(gòu)的不同可以分為重錘杠桿式、彈簧式和脈沖式三種。
1.重錘杠桿式安全閥
重錘杠桿式安全閥是利用重錘和杠桿來(lái)平衡作用在閥瓣上的力。根據(jù)杠桿原理，它可以使用質(zhì)量較小的重錘通過(guò)杠桿的增大作用獲得較大的作用力，并通過(guò)移動(dòng)重錘的位置(或變換重錘的質(zhì)量)來(lái)調(diào)整安全閥的開(kāi)啟壓力。
重錘杠桿式安全閥結(jié)構(gòu)簡(jiǎn)單，調(diào)整容易而又比較準(zhǔn)確，所加的載荷不會(huì)因閥瓣的升高而有較大的增加，適用于溫度較高的場(chǎng)合，過(guò)去用得比較普遍，特別是用在鍋爐和溫度較高的壓力容器上。但重錘杠桿式安全閥結(jié)構(gòu)比較笨重，加載機(jī)構(gòu)容易振動(dòng)，并常因振動(dòng)而產(chǎn)生泄漏；其回座壓力較低，開(kāi)啟后不易關(guān)閉及保持嚴(yán)密。
2.彈簧微啟式安全閥
彈簧微啟式安全閥是利用壓縮彈簧的力來(lái)平衡作用在閥瓣上的力。螺旋圈形彈簧的壓縮量可以通過(guò)轉(zhuǎn)動(dòng)它上面的調(diào)整螺母來(lái)調(diào)節(jié)，利用這種結(jié)構(gòu)就可以根據(jù)需要校正安全閥的開(kāi)啟(整定)壓力。彈簧微啟式安全閥結(jié)構(gòu)輕便緊湊，靈敏度也比較高，安裝位置不受限制，而且因?yàn)閷?duì)振動(dòng)的敏感性小，所以可用于移動(dòng)式的壓力容器上。這種安全閥的缺點(diǎn)是所加的載荷會(huì)隨著閥的開(kāi)啟而發(fā)生變化，即隨著閥瓣的升高，彈簧的壓縮量增大，作用在閥瓣上的力也跟著增加。這對(duì)安全閥的迅速開(kāi)啟是不利的。另外，閥上的彈簧會(huì)由于長(zhǎng)期受高溫的影響而使彈力減小。用于溫度較高的容器上時(shí)，常常要考慮彈簧的隔熱或散熱問(wèn)題，從而使結(jié)構(gòu)變得復(fù)雜起來(lái)。
3.脈沖式安全閥
脈沖式安全閥由主閥和輔閥構(gòu)成，通過(guò)輔閥的脈沖作用帶動(dòng)主閥動(dòng)作、其結(jié)構(gòu)復(fù)雜，通常只適用于安全泄放量很大的鍋爐和壓力容器。

鍛壓機(jī)床
鍛壓機(jī)床是金屬和機(jī)械冷加工用的設(shè)備，他只改變金屬的外形狀。鍛壓機(jī)床包括卷板機(jī)，剪板機(jī)，沖床，壓力機(jī)，液壓機(jī)，油壓機(jī)，折彎?rùn)C(jī)等。

液壓機(jī)是一種以液體為工作介質(zhì)，根據(jù)帕斯卡原理制成的用于傳遞能量以實(shí)現(xiàn)各種工藝的機(jī)器。液壓機(jī)一般由本機(jī)（主機(jī)）、動(dòng)力系統(tǒng)及液壓控制系統(tǒng)三部分組成。液壓機(jī)分類(lèi)有閥門(mén)液壓機(jī)，液體液壓機(jī)，工程液壓機(jī)。

液壓機(jī)（又名：油壓機(jī)）液壓機(jī)是一種利用液體靜壓力來(lái)加工金屬、塑料、橡膠、木材、粉末等制品的機(jī)械。它常用于壓制工藝和壓制成形工藝，如：鍛壓、沖壓、冷擠、校直、彎曲、翻邊、薄板拉深、粉末冶金、壓裝等等。
它的原理是利用帕斯卡定律制成的利用液體壓強(qiáng)傳動(dòng)的機(jī)械，種類(lèi)很多。當(dāng)然，用途也根據(jù)需要是多種多樣的。如按傳遞壓強(qiáng)的液體種類(lèi)來(lái)分，有油壓機(jī)和水壓機(jī)兩大類(lèi)。

溢流閥一般有兩種結(jié)構(gòu)：1、直動(dòng)型溢流閥 。2、先導(dǎo)式溢流閥。
對(duì)溢流閥的主要要求：調(diào)壓范圍大，調(diào)壓偏差小，壓力振擺小，動(dòng)作靈敏，過(guò)載能力大，噪聲小。
先導(dǎo)型溢流閥的導(dǎo)閥部分結(jié)構(gòu)尺寸較小，調(diào)壓彈簧不必很強(qiáng)，因此壓力調(diào)整比較輕便。但因先導(dǎo)型溢流閥要在先導(dǎo)閥和主閥都動(dòng)作后才能起控制作用，因此反應(yīng)不如直動(dòng)型溢流閥靈敏。
與三節(jié)同心結(jié)構(gòu)相比，二節(jié)同心結(jié)構(gòu)的特點(diǎn)是：①主閥芯僅與閥套和主閥座有同心度要求，免去了與閥蓋的配合，故結(jié)構(gòu)簡(jiǎn)單，加工和裝配方便。②過(guò)流面積大，在相同流量的情況下，主閥開(kāi)啟高度小；或者在相同開(kāi)啟高度的情況下，其通流能力大，因此，可做得體積小、重量輕。③主閥芯與閥套可以通用化，便于組織批量生產(chǎn)。
