一、風(fēng)機(jī)安全閥概述

風(fēng)機(jī)安全閥是我公司針對(duì)傳統(tǒng)安全閥存在的問(wèn)題，并結(jié)合風(fēng)機(jī)的特定工況和參數(shù)而研制開發(fā)的一種新型的閥門產(chǎn)品，它用于保護(hù)風(fēng)機(jī)及設(shè)備的安全，當(dāng)風(fēng)機(jī)及設(shè)備中的壓力異常升高到某一規(guī)定值（安全閥的開啟壓力）時(shí)，安全閥能夠自動(dòng)開啟并排放介質(zhì)，以防止壓力繼續(xù)升高，當(dāng)風(fēng)機(jī)及設(shè)備中的壓力降低到某一規(guī)定值（安全閥的回座壓力）時(shí)，安全閥自動(dòng)關(guān)閉。

    該產(chǎn)品獲得了國(guó)家。號(hào)為：ZL01 2 64819.1。

    與傳統(tǒng)安全閥比較，具有如下特點(diǎn)：

    1、由于風(fēng)機(jī)主要用于低壓空氣介質(zhì)，因此風(fēng)機(jī)安全閥取消了出口排放法蘭，而采用閥體四周均布的小孔直接排放介質(zhì)，同時(shí)將彈簧腔體直接設(shè)置在閥瓣背部，采用上述結(jié)構(gòu)后，閥門的結(jié)構(gòu)更為緊湊，介質(zhì)的排放更加通暢，而閥門的重量卻只有傳統(tǒng)安全閥的1/3～1/5。



    2、風(fēng)機(jī)安全閥在閥瓣與閥座間采用了壓力積聚槽的結(jié)構(gòu)設(shè)計(jì)，與傳統(tǒng)安全閥采用調(diào)節(jié)圈及定為螺釘?shù)慕Y(jié)構(gòu)相比較，結(jié)構(gòu)更加簡(jiǎn)單，閥門的使用也更加方便，而閥門的性能卻更加穩(wěn)定。



    3、傳統(tǒng)安全閥的zui低開啟壓力一般為0.1MPa，而用于風(fēng)機(jī)的安全閥，其開啟壓力往往要求低于0.1MPa，傳統(tǒng)安全閥即使改用剛度較小的彈簧，在低壓下也不能準(zhǔn)確、靈敏的動(dòng)作。而風(fēng)機(jī)安全閥設(shè)計(jì)的開啟壓力范圍為0.02～0.2MPa，因此風(fēng)機(jī)安全閥在低壓下能夠非常準(zhǔn)確、靈敏的動(dòng)作。

    4、風(fēng)機(jī)安全閥的彈簧通過(guò)閥桿作用在閥瓣上的力作用點(diǎn)與閥瓣密封面非常接近，而傳統(tǒng)安全閥力的作用點(diǎn)遠(yuǎn)離閥瓣密封平面，因此，與傳統(tǒng)安全閥相比，風(fēng)機(jī)安全閥的動(dòng)作性能更加穩(wěn)定可靠。

    5、傳統(tǒng)安全閥通過(guò)出口通道向一個(gè)方向排放介質(zhì)，因此介質(zhì)排放時(shí)容易引起系統(tǒng)的振動(dòng)，而風(fēng)機(jī)安全閥是通過(guò)閥體上周向均布的小孔向四周均勻排放介質(zhì)，因此，閥門動(dòng)作時(shí)平穩(wěn)無(wú)振動(dòng)。

    6、風(fēng)機(jī)安全閥沒(méi)有調(diào)節(jié)圈，使用非常簡(jiǎn)單，安全閥出廠時(shí)已按用戶要求的開啟壓力調(diào)試好，用戶直接將安全閥安裝在系統(tǒng)上即可使用。

二、風(fēng)機(jī)安全閥型號(hào)、材質(zhì)

2、安全閥公稱通徑的確定

    為了使風(fēng)機(jī)安全閥能有效地保護(hù)風(fēng)機(jī)設(shè)備的安全，安全閥在排放壓力下的排量應(yīng)該略大于風(fēng)機(jī)的排量。根據(jù)安全閥的排量表確定安全閥的公稱通徑。對(duì)于排量表未列出的開啟壓力及排放壓力數(shù)值，可通過(guò)插值法計(jì)算相應(yīng)的排量。可以采用多臺(tái)安全閥并聯(lián)使用來(lái)擴(kuò)大安全閥的排量。可以采用多臺(tái)安全閥并聯(lián)使用來(lái)擴(kuò)大安全閥的排量。

3、安全閥的彈簧壓力分級(jí)

    為了使安全閥具有良好的動(dòng)作性能，對(duì)于相同口徑不同開啟壓力的安全閥需要配置不同剛度的彈簧，我公司對(duì)一個(gè)系列的彈簧進(jìn)行了壓力分級(jí)，每一規(guī)格的彈簧只能在一定的開啟壓力范圍內(nèi)使用，由于每一規(guī)格的彈簧適用的壓力范圍非常有限，因此，用戶訂貨時(shí)除了需要告知閥門的型號(hào)、公稱通徑以外，還須告知安全閥的開啟壓力，以便制造廠正確的配置彈簧，保證安全閥具有良好的動(dòng)作性能。

4、安全閥的使用

    我公司安全閥出廠時(shí)已經(jīng)按訂貨合同中的開啟壓力試驗(yàn)、調(diào)試完畢，用戶可直接安裝使用。安全閥出廠時(shí)有鉛封，一般情況下用戶不要隨意拆卸安全閥，以免影響安全閥的性能。
