全焊接球閥產品概述

全焊接球閥是一(yi)種(zhong)具(ju)有浮動閥(fa)座，采用(yong)(yong)鋼管整(zheng)體(ti)焊接而成(cheng)，適(shi)用(yong)(yong)于使(shi)(shi)用(yong)(yong)溫度為(wei)(wei)0℃~180℃，工(gong)作介質為(wei)(wei)水、蒸汽(qi)、燃(ran)(ran)氣(qi)的(de)焊接球(qiu)閥(fa)，其閥(fa)體(ti)通常(chang)采用(yong)(yong)整(zheng)體(ti)鍛造制作或模(mo)壓加工(gong)成(cheng)型的(de)鋼管或板材(cai)卷制。該閥(fa)按(an)體(ti)型分為(wei)(wei)橢(tuo)圓(yuan)(yuan)形(xing)(xing)(xing)(xing)、筒(tong)形(xing)(xing)(xing)(xing)及球(qiu)形(xing)(xing)(xing)(xing)三種(zhong)，橢(tuo)圓(yuan)(yuan)形(xing)(xing)(xing)(xing)的(de)閥(fa)體(ti)兩端(duan)圓(yuan)(yuan)弧(hu)(hu)形(xing)(xing)(xing)(xing)采用(yong)(yong)工(gong)裝(zhuang)冷壓成(cheng)形(xing)(xing)(xing)(xing)，兩邊(bian)圓(yuan)(yuan)弧(hu)(hu)平滑過渡，減少(shao)應(ying)力(li)集中(zhong)，省略(lve)了中(zhong)法蘭(lan)，可以減輕(qing)(qing)閥(fa)門重(zhong)量(liang)，節省制造成(cheng)本，筒(tong)形(xing)(xing)(xing)(xing)的(de)邊(bian)體(ti)為(wei)(wei)整(zheng)體(ti)鍛件，強度高，相比圓(yuan)(yuan)體(ti)能承受更大(da)的(de)管道應(ying)力(li)，適(shi)用(yong)(yong)于大(da)口徑，球(qiu)形(xing)(xing)(xing)(xing)的(de)閥(fa)體(ti)結構為(wei)(wei)兩個(ge)半(ban)圓(yuan)(yuan)(弧(hu)(hu)形(xing)(xing)(xing)(xing))組成(cheng)，重(zhong)量(liang)輕(qing)(qing)，可以減少(shao)材(cai)料成(cheng)本，減輕(qing)(qing)管道重(zhong)量(liang)負(fu)荷，主副閥(fa)體(ti)中(zhong)部焊縫離(li)閥(fa)座位置(zhi)較遠，焊接時(shi)，熱影響和變形(xing)(xing)(xing)(xing)量(liang)對閥(fa)座周(zhou)邊(bian)影響較小(xiao)。本產(chan)品具(ju)有結構簡單(dan)、免維護和使(shi)(shi)用(yong)(yong)時(shi)間長(chang)等特點，可以廣泛用(yong)(yong)于城鎮供熱系統和城市燃(ran)(ran)氣(qi)管道工(gong)程(cheng)。
