鋼波紋管的強度需要通過哪些途徑來實現?

波紋管(guan)截止閥,也叫波紋管(guan)密封截止閥,通過(guo)自動(dong)滾焊焊接,在(zai)流體介質(zhi)和大氣之間(jian)形成一個(ge)金屬屏障,確保閥桿零泄漏的設計。并且(qie)因(yin)為(wei)連接利便、可靠,在(zai)海內外得到應用。

側(ce)(ce)壁鼓脹是波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)子(zi)午向(xiang)剛(gang)度(du)不足的典型(xing)表現,從強度(du)角(jiao)度(du)來講,波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)產(chan)生的側(ce)(ce)壁鼓脹形式的子(zi)午向(xiang)屈服(fu)是由于子(zi)午向(xiang)應力(li)過大(da)所引起的,U型(xing)波(bo)(bo)(bo)紋(wen)(wen)(wen)截面較大(da)的子(zi)午向(xiang)應力(li)將會引起側(ce)(ce)壁鼓脹,任何波(bo)(bo)(bo)紋(wen)(wen)(wen)形狀的變(bian)化(hua)都會引起側(ce)(ce)壁間隙的減小,降(jiang)低波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)位移補償能力(li),對疲勞(lao)壽命(ming)也有可能產(chan)生一定(ding)的影響(xiang),顯(xian)然,嚴(yan)重的側(ce)(ce)壁鼓脹是不允許的,當波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)產(chan)生嚴(yan)重側(ce)(ce)壁鼓脹時,環板(ban)屈服(fu)區域(yu)大(da),變(bian)形量大(da),對波(bo)(bo)(bo)紋(wen)(wen)(wen)管(guan)位移補償和疲勞(lao)壽命(ming)都有一定(ding)的影響(xiang)。

鋼制波紋涵管

1929年,在(zai)波(bo)(bo)紋(wen)(wen)管(guan)的(de)布局進步行了(le)又一(yi)次技術革(ge)命,也徹(che)底解(jie)決了(le)不銹鋼金屬(shu)軟管(guan)因為曲折時填墊橡膠(jiao)帶或石棉繩的(de)凹槽發作不均勻改變(bian)而損失(shi)密封功能的(de)問題,然后拓荒了(le)波(bo)(bo)紋(wen)(wen)管(guan)開展的(de)寬(kuan)廣(guang)遠景。大家用鋼和銅鋅合金資(zi)料制(zhi)成了(le)全體波(bo)(bo)紋(wen)(wen)管(guan),就是用無(wu)縫(feng)的(de)或有焊縫(feng)的(de)管(guan)材制(zhi)成的(de)波(bo)(bo)紋(wen)(wen)管(guan),它依托波(bo)(bo)紋(wen)(wen)側壁的(de)彈性(xing)變(bian)形(xing)來堅(jian)持必定的(de)可(ke)壓縮性(xing)或可(ke)拉伸性(xing)一(yi)起,包管(guan)牢靠的(de)密封。

從20世紀50年(nian)代起,雙層(ceng)、三層(ceng)、多(duo)層(ceng)的(de)(de)波紋(wen)管(guan),特別(bie)是極薄壁不銹鋼材波紋(wen)管(guan)開展(zhan)得很快。為(wei)了滿意運用需求,大(da)家選用焊接(jie)、電鑄、機加(jia)、液壓和(he)機械旋(xuan)壓等各(ge)種工(gong)藝方法(fa)來制作波紋(wen)管(guan)。小公(gong)稱通(tong)徑(jing)為(wei)2毫米,更大(da)公(gong)稱通(tong)徑(jing)可(ke)達(da)400~500毫米,乃至有通(tong)徑(jing)為(wei)lO米的(de)(de)巨形波紋(wen)管(guan)。波紋(wen)數少l~2個(ge),多(duo)可(ke)達(da)接(jie)連幾(ji)百、幾(ji)千,乃至幾(ji)萬個(ge)。
