錐形封(feng)頭(tou)是(shi)殼體(ti)表(biao)面(mian)為錐面(mian)的(de)封(feng)頭(tou)。錐體(ti)的(de)主體(ti)部分在內壓(ya)作用下，zui大薄膜應力發生在大端。它有什么(me)特(te)點？用途呢(ni)？聽(ting)聽(ting)錐形封(feng)頭(tou)廠家怎么(me)說吧！

?錐(zhui)形(xing)封(feng)(feng)頭(tou)(tou)(tou)在焊(han)接上分為對焊(han)封(feng)(feng)頭(tou)(tou)(tou)，承插焊(han)封(feng)(feng)頭(tou)(tou)(tou)。用于(yu)各種容器(qi)設(she)備(bei)，如儲罐(guan)、換熱器(qi)、塔、反應(ying)釜、鍋爐和分離設(she)備(bei)等。錐(zhui)形(xing)封(feng)(feng)頭(tou)(tou)(tou)直徑(jing)較(jiao)(jiao)小(xiao)的半球形(xing)封(feng)(feng)頭(tou)(tou)(tou)可整(zheng) 體壓制成型，但(dan)直徑(jing)較(jiao)(jiao)大(da)(da)的由于(yu)其 探度(du)較(jiao)(jiao)大(da)(da)，整(zheng)體壓制有困難，故需 采(cai)用數塊大(da)(da)小(xiao)相同(tong)的梯(ti)形(xing)球瓣和 頂部中心的一塊圓形(xing)球面板(ban)(球 冠)組焊(han)而成。

?錐形(xing)(xing)封頭的特點是可使介質通(tong)過時均勻改變速度，便于卸凈(jing)粘稠液體和含(han)固體顆粒物料，但(dan)力(li)學性能較差，在與圓(yuan)筒或(huo)接(jie)管連接(jie)處因形(xing)(xing)狀(zhuang)突變產生(sheng)的不連續應力(li)較大。為(wei)了降低(di)不連續應力(li)，可在錐殼的大端或(huo)小端采用圓(yuan)弧過渡的有折邊結(jie)構(gou)(gou)或(huo)局(ju)部增厚結(jie)構(gou)(gou)。錐形(xing)(xing)封頭廠(chang)家

?錐(zhui)(zhui)形封頭(tou)(tou)的(de)用途：錐(zhui)(zhui)形封頭(tou)(tou)錐(zhui)(zhui)體(ti)的(de)主(zhu)體(ti)部分在內壓作用下，zui大(da)薄(bo)膜應(ying)力(li)發生在大(da)端(duan)。錐(zhui)(zhui)體(ti)和(he)圓筒部分連接處，由于幾何(he)不連續性，曲率半(ban)徑突變，貴州(zhou)大(da)型錐(zhui)(zhui)體(ti)封頭(tou)(tou)，因此該處會產生較(jiao)大(da)的(de)橫向推(tui)力(li)，引起較(jiao)大(da)邊(bian)緣應(ying)力(li)，容易發生彎(wan)曲，故需加(jia)強。

按照錐形封(feng)頭(tou)(tou)半(ban)(ban)頂角a的(de)大(da)小不同，制作成不同結構的(de)錐形封(feng)頭(tou)(tou):當a≤30°時，錐形封(feng)頭(tou)(tou)的(de)大(da)小端均可(ke)無折(zhe)邊，錐形封(feng)頭(tou)(tou)與(yu)筒體(ti)可(ke)直接(jie)相連，當錐形封(feng)頭(tou)(tou)半(ban)(ban)頂角30 有折(zhe)邊的(de)封(feng)頭(tou)(tou)結構;當錐形封(feng)頭(tou)(tou)半(ban)(ban)頂角45° 。錐形封(feng)頭(tou)(tou)廣泛應用于許(xu)多化(hua)工設(she)備的(de)底蓋，便于收集(ji)與(yu)卸除(chu)這些(xie)設(she)備中的(de)固(gu)體(ti)物(wu)料。避(bi)免(mian)沉淀堆(dui)積。此(ci)外，有些(xie)塔設(she)備上(shang)、下部分(fen)的(de)直徑(jing)不等(deng)，也常用錐形殼(ke)體(ti)將直徑(jing)不等(deng)的(de)兩(liang)段塔體(ti)連接(jie)起來，這時的(de)錐形殼(ke)體(ti)稱為變徑(jing)段。
