反拱形爆破片分類：
反(fan)(fan)拱(gong)鱷齒(chi)型(xing)爆(bao)(bao)破(po)(po)片（YE）結(jie)構特點：反(fan)(fan)拱(gong)形(xing)(xing)爆(bao)(bao)破(po)(po)片，凸面處(chu)于壓(ya)力系統高壓(ya)側。反(fan)(fan)拱(gong)鱷齒(chi)型(xing)爆(bao)(bao)破(po)(po)片所受壓(ya)力達到其爆(bao)(bao)破(po)(po)壓(ya)力時，拱(gong)形(xing)(xing)爆(bao)(bao)破(po)(po)片首(shou)先失(shi)穩反(fan)(fan)轉，接著被(bei)(bei)其后的齒(chi)圈(quan)沿(yan)周邊處(chu)剪開，被(bei)(bei)剪開的部(bu)分由擋架(jia)拖住，以免(mian)飛出(chu)。爆(bao)(bao)破(po)(po)片失(shi)穩翻轉時因觸及(ji)環形(xing)(xing)鱷齒(chi)而(er)破(po)(po)裂的反(fan)(fan)拱(gong)形(xing)(xing)爆(bao)(bao)破(po)(po)片。
這種爆(bao)(bao)破(po)(po)片(pian)特點是適(shi)用(yong)于(yu)更低的(de)壓力下，爆(bao)(bao)破(po)(po)片(pian)厚(hou)度比帶刀(dao)型爆(bao)(bao)破(po)(po)片(pian)薄，拱面更容易受到損傷。
反拱刀架型爆破(po)片（YD）結構特點：反拱形爆破(po)片，凸面處于壓力系統高壓側。爆破(po)片為單層膜片，與帶有刀架的夾持器相配，膜片失穩(wen)翻轉(zhuan)后靠夾持器上(shang)刀架使爆破(po)片破(po)裂泄放。
反拱開(kai)縫(feng)爆(bao)破(po)(po)片(pian)（YF）結構特點：反拱形爆(bao)破(po)(po)片(pian)，凸(tu)面(mian)處于壓力系統高壓側(ce)。反拱開(kai)縫(feng)爆(bao)破(po)(po)片(pian)，根據歐拉定(ding)理，由(you)開(kai)縫(feng)的(de)承壓膜(mo)設定(ding)壓力，密(mi)封(feng)膜(mo)起到密(mi)封(feng)作用，到達設定(ding)壓力，爆(bao)破(po)(po)片(pian)翻(fan)轉，密(mi)封(feng)膜(mo)被割開(kai)即泄(xie)放壓力。
反(fan)拱(gong)(gong)帶槽型爆破片(pian)(pian)(pian)（YC）結構(gou)特點：反(fan)拱(gong)(gong)形爆破片(pian)(pian)(pian)，凸面處于壓力系(xi)統高壓側。爆破片(pian)(pian)(pian)上(shang)加工(gong)有減弱槽的反(fan)拱(gong)(gong)形爆破片(pian)(pian)(pian)。
反(fan)拱帶槽型爆(bao)破(po)片(pian)(pian)不僅具備反(fan)拱帶刀(dao)型爆(bao)破(po)片(pian)(pian)的(de)優點，而(er)且無需致(zhi)破(po)刀(dao)架，爆(bao)破(po)后排放面(mian)積很大。這(zhe)種爆(bao)破(po)片(pian)(pian)的(de) 顯著特點是，爆(bao)破(po)后不產生碎片(pian)(pian)，適(shi)用(yong)(yong)(yong)于(yu)排放介質(zhi)為易燃易爆(bao)的(de)場(chang)合(he)(he)。反(fan)拱帶槽型爆(bao)破(po)片(pian)(pian)即(ji)使(shi)是爆(bao)破(po)片(pian)(pian)拱形爆(bao)破(po)片(pian)(pian)的(de)厚度(du)較大（因而(er)適(shi)用(yong)(yong)(yong)于(yu)爆(bao)破(po)壓(ya)力更高的(de)場(chang)合(he)(he)），只(zhi)要在(zai)制造時控制適(shi)當的(de)槽深，也可以保證(zheng)拱形爆(bao)破(po)片(pian)(pian)失穩(wen)反(fan)轉后立即(ji)致(zhi)破(po)，適(shi)用(yong)(yong)(yong)壓(ya)力范(fan)圍比較廣。
