产品特点:阀(fa)(fa)(fa)(fa)门采(cai)用(yong)三偏(pian)心结(jie)构,阀(fa)(fa)(fa)(fa)门在(zai)开(kai)启(qi)时(shi)(shi)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)副(fu)之间(jian)能(neng)快速脱离,减少(shao)了密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)副(fu)之间(jian)的(de)(de)(de)(de)(de)(de)相对摩擦。阀(fa)(fa)(fa)(fa)门在(zai)关闭时(shi)(shi),具(ju)有越(yue)关越(yue)紧及密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)圈(quan)(quan)磨损补偿的(de)(de)(de)(de)(de)(de)功(gong)能(neng);凸起的(de)(de)(de)(de)(de)(de)、锥形(xing)阀(fa)(fa)(fa)(fa)座避免实心颗粒淤积(ji)影(ying)响密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)。阀(fa)(fa)(fa)(fa)座密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)面采(cai)用(yong)堆(dui)焊硬质合(he)金于(yu)阀(fa)(fa)(fa)(fa)体(ti)(ti)上,能(neng)够有效(xiao)防止(zhi)锈蚀等情况(kuang);采(cai)用(yong)多层(ceng)次金属硬密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)蝶阀(fa)(fa)(fa)(fa),阀(fa)(fa)(fa)(fa)体(ti)(ti)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)层(ceng)为软硬层(ceng)叠式(shi)金属片制成(cheng)的(de)(de)(de)(de)(de)(de)弹(dan)(dan)性(xing)(xing)(xing)(xing)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)圈(quan)(quan)形(xing)成(cheng)迷(mi)宫式(shi)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng),具(ju)有金属硬密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)和(he)弹(dan)(dan)性(xing)(xing)(xing)(xing)软密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)的(de)(de)(de)(de)(de)(de)双(shuang)重优点。在(zai)阀(fa)(fa)(fa)(fa)门内腔(qiang)有积(ji)尘的(de)(de)(de)(de)(de)(de)情况(kuang)下,阀(fa)(fa)(fa)(fa)门关闭时(shi)(shi),密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)副(fu)之间(jian)形(xing)成(cheng)的(de)(de)(de)(de)(de)(de)剪刀口可以将积(ji)尘消除而不会影(ying)响密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng);阀(fa)(fa)(fa)(fa)瓣密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng),沿(yan)着圆周(zhou)均(jun)匀压缩(suo),产生(sheng)(sheng)焊接般的(de)(de)(de)(de)(de)(de)效(xiao)果,使得密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)环弯曲,作(zuo)用(yong)犹如(ru)弹(dan)(dan)簧一(yi)般。弹(dan)(dan)性(xing)(xing)(xing)(xing)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)确(que)保液体(ti)(ti)或(huo)气体(ti)(ti)“零(ling)泄漏”。密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)的(de)(de)(de)(de)(de)(de)弹(dan)(dan)性(xing)(xing)(xing)(xing)使得阀(fa)(fa)(fa)(fa)瓣在(zai)热循环运动中能(neng)够保持关闭的(de)(de)(de)(de)(de)(de)气密(mi)(mi)(mi)(mi)(mi)性(xing)(xing)(xing)(xing)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng);关闭期间(jian)的(de)(de)(de)(de)(de)(de)扭矩产生(sheng)(sheng)阀(fa)(fa)(fa)(fa)座力(li)(li),并(bing)均(jun)匀一(yi)致(zhi)的(de)(de)(de)(de)(de)(de)作(zuo)用(yong)在(zai)整个(ge)圆周(zhou)周(zhou)围。弹(dan)(dan)性(xing)(xing)(xing)(xing)密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)弯曲并(bing)充满活(huo)力(li)(li),保持了阀(fa)(fa)(fa)(fa)座的(de)(de)(de)(de)(de)(de)形(xing)状。压缩(suo)力(li)(li)沿(yan)着周(zhou)长均(jun)匀作(zuo)用(yong),使得阀(fa)(fa)(fa)(fa)门能(neng)够实现双(shuang)向紧密(mi)(mi)(mi)(mi)(mi)关闭。密(mi)(mi)(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)(feng)的(de)(de)(de)(de)(de)(de)弹(dan)(dan)性(xing)(xing)(xing)(xing)使得阀(fa)(fa)(fa)(fa)门阀(fa)(fa)(fa)(fa)体(ti)(ti)和(he)阀(fa)(fa)(fa)(fa)瓣能(neng)够接触(chu)或(huo)扩张,避免了由于(yu)温(wen)度波动而产生(sheng)(sheng)堵塞的(de)(de)(de)(de)(de)(de)危(wei)险(xian)。
