全焊接球閥產品概述

全焊接球閥是一種(zhong)(zhong)具(ju)有浮動閥(fa)座，采(cai)用(yong)鋼(gang)管整(zheng)(zheng)體(ti)(ti)(ti)焊(han)(han)接(jie)(jie)而(er)成(cheng)(cheng)，適用(yong)于(yu)(yu)使(shi)用(yong)溫(wen)度為(wei)0℃~180℃，工作(zuo)(zuo)介質(zhi)為(wei)水(shui)、蒸汽、燃(ran)氣的(de)焊(han)(han)接(jie)(jie)球閥(fa)，其閥(fa)體(ti)(ti)(ti)通常采(cai)用(yong)整(zheng)(zheng)體(ti)(ti)(ti)鍛造制作(zuo)(zuo)或(huo)模(mo)壓加工成(cheng)(cheng)型的(de)鋼(gang)管或(huo)板材(cai)卷(juan)制。該閥(fa)按體(ti)(ti)(ti)型分為(wei)橢圓(yuan)(yuan)(yuan)形(xing)(xing)、筒(tong)形(xing)(xing)及球形(xing)(xing)三種(zhong)(zhong)，橢圓(yuan)(yuan)(yuan)形(xing)(xing)的(de)閥(fa)體(ti)(ti)(ti)兩(liang)端圓(yuan)(yuan)(yuan)弧(hu)形(xing)(xing)采(cai)用(yong)工裝冷壓成(cheng)(cheng)形(xing)(xing)，兩(liang)邊(bian)(bian)圓(yuan)(yuan)(yuan)弧(hu)平(ping)滑過渡(du)，減(jian)少應(ying)力集中(zhong)，省略了中(zhong)法蘭(lan)，可(ke)以減(jian)輕閥(fa)門重(zhong)量(liang)，節省制造成(cheng)(cheng)本(ben)，筒(tong)形(xing)(xing)的(de)邊(bian)(bian)體(ti)(ti)(ti)為(wei)整(zheng)(zheng)體(ti)(ti)(ti)鍛件(jian)，強度高，相比圓(yuan)(yuan)(yuan)體(ti)(ti)(ti)能(neng)承受(shou)更大的(de)管道應(ying)力，適用(yong)于(yu)(yu)大口徑，球形(xing)(xing)的(de)閥(fa)體(ti)(ti)(ti)結構為(wei)兩(liang)個(ge)半(ban)圓(yuan)(yuan)(yuan)(弧(hu)形(xing)(xing))組成(cheng)(cheng)，重(zhong)量(liang)輕，可(ke)以減(jian)少材(cai)料成(cheng)(cheng)本(ben)，減(jian)輕管道重(zhong)量(liang)負(fu)荷(he)，主副(fu)閥(fa)體(ti)(ti)(ti)中(zhong)部焊(han)(han)縫離閥(fa)座位置較遠，焊(han)(han)接(jie)(jie)時，熱影響和(he)變形(xing)(xing)量(liang)對閥(fa)座周邊(bian)(bian)影響較小。本(ben)產品(pin)具(ju)有結構簡(jian)單(dan)、免維護和(he)使(shi)用(yong)時間長(chang)等特(te)點，可(ke)以廣泛用(yong)于(yu)(yu)城鎮供熱系(xi)統(tong)和(he)城市(shi)燃(ran)氣管道工程。
