椭圆封头

椭(tuo)圆(yuan)(yuan)(yuan)封(feng)(feng)(feng)头(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)又名为(wei)(wei)(wei)椭(tuo)圆(yuan)(yuan)(yuan)形(xing)(xing)(xing)(xing)封(feng)(feng)(feng)头(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)、椭(tuo)圆(yuan)(yuan)(yuan)封(feng)(feng)(feng)头(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)即为(wei)(wei)(wei)由(you)旋(xuan)(xuan)转椭(tuo)圆(yuan)(yuan)(yuan)球(qiu)面(mian)和圆(yuan)(yuan)(yuan)筒形(xing)(xing)(xing)(xing)直(zhi)(zhi)段两(liang)部(bu)分组(zu)成的(de)(de)(de)封(feng)(feng)(feng)头(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)。 其作用(yong)就(jiu)是(shi)1.管道到头(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)了,不准备(bei)现延(yan)伸了,就(jiu)用(yong)封(feng)(feng)(feng)头(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)焊到管子上(shang)(shang),做(zuo)为(wei)(wei)(wei)一个(ge)(ge)末(mo)端(duan)来使用(yong)。2.用(yong)在压(ya)(ya)力容器(qi)上(shang)(shang),上(shang)(shang)下各有一个(ge)(ge)封(feng)(feng)(feng)头(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou),中间是(shi)一个(ge)(ge)直(zhi)(zhi)管段,做(zuo)为(wei)(wei)(wei)压(ya)(ya)力容器(qi)的(de)(de)(de)罐子用(yong)。 旋(xuan)(xuan)转椭(tuo)圆(yuan)(yuan)(yuan)球(qiu)面(mian)母线的(de)(de)(de)长、短(duan)轴之比为(wei)(wei)(wei)2.0的(de)(de)(de)椭(tuo)圆(yuan)(yuan)(yuan)形(xing)(xing)(xing)(xing)封(feng)(feng)(feng)头(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou),习惯上(shang)(shang)称为(wei)(wei)(wei)标准椭(tuo)圆(yuan)(yuan)(yuan)形(xing)(xing)(xing)(xing)封(feng)(feng)(feng)头(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)。 椭(tuo)圆(yuan)(yuan)(yuan)封(feng)(feng)(feng)头(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)的(de)(de)(de)力学(xue)性(xing)能(neng)仅次于半球(qiu)封(feng)(feng)(feng)头(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou),但优于碟形(xing)(xing)(xing)(xing)封(feng)(feng)(feng)头(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)。由(you)于椭(tuo)圆(yuan)(yuan)(yuan)封(feng)(feng)(feng)头(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)的(de)(de)(de)深(shen)度介于半球(qiu)形(xing)(xing)(xing)(xing)和碟形(xing)(xing)(xing)(xing)封(feng)(feng)(feng)头(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)之间,对冲压(ya)(ya)设备(bei)及模具的(de)(de)(de)要求、制(zhi)(zhi)造难(nan)度亦介于两(liang)者之间,即比半球(qiu)封(feng)(feng)(feng)头(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)容易(yi),比碟形(xing)(xing)(xing)(xing)封(feng)(feng)(feng)头(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)困难(nan)。近年来由(you)于采用(yong)旋(xuan)(xuan)压(ya)(ya)制(zhi)(zhi)造工(gong)艺,为(wei)(wei)(wei)制(zhi)(zhi)造大直(zhi)(zhi)径椭(tuo)圆(yuan)(yuan)(yuan)形(xing)(xing)(xing)(xing)封(feng)(feng)(feng)头(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)带来了方便(bian)。 椭(tuo)圆(yuan)(yuan)(yuan)封(feng)(feng)(feng)头(tou)(tou)(tou)(tou)(tou)(tou)(tou)(tou)因综合性(xing)能(neng)较好,被(bei)广泛用(yong)于中低(di)压(ya)(ya)容器(qi)。
