復式萬向鉸鏈波紋補償器

　　波(bo)紋(wen)管是(shi)構(gou)成波(bo)紋(wen)補(bu)償器最(zui)主要元(yuan)件(jian)。波(bo)紋(wen)管通過(guo)附(fu)加的拉桿(gan)、鉸(jiao)鏈等附(fu)件(jian)與波(bo)紋(wen)管元(yuan)件(jian)相互組(zu)合即(ji)可以組(zu)成各(ge)種功能的補(bu)償器。波(bo)紋(wen)補(bu)償器組(zu)合分為軸向波(bo)紋(wen)補(bu)償器、角(jiao)向型波(bo)紋(wen)補(bu)償器、復式拉桿(gan)補(bu)償器等。

　一，產品簡介及用(yong)途

　　在(zai)考(kao)慮(lv)(lv)管(guan)道熱補(bu)(bu)(bu)(bu)償(chang)時(shi)，應(ying)充分(fen)考(kao)慮(lv)(lv)利(li)用(yong)(yong)管(guan)道的自(zi)然彎曲來吸(xi)收(shou)熱力管(guan)道的溫(wen)度變形，自(zi)然補(bu)(bu)(bu)(bu)償(chang)每段(duan)臂長(chang)一(yi)般不宜大(da)于 20。當自(zi)然補(bu)(bu)(bu)(bu)償(chang)不能滿足管(guan)道的溫(wen)度變形時(shi)，則需要(yao)采用(yong)(yong)補(bu)(bu)(bu)(bu)償(chang)器進(jin)行熱力補(bu)(bu)(bu)(bu)償(chang)。波(bo)紋補(bu)(bu)(bu)(bu)償(chang)器作為熱網管(guan)道的關鍵(jian)組件，在(zai)熱網的使用(yong)(yong)量也越來越大(da)，特(te)別是角向型補(bu)(bu)(bu)(bu)償(chang)器具有補(bu)(bu)(bu)(bu)償(chang)量大(da)，補(bu)(bu)(bu)(bu)償(chang)距(ju)離(li)長(chang)等特(te)點，在(zai)對高(gao)溫(wen)介質的管(guan)道上進(jin)行熱力補(bu)(bu)(bu)(bu)償(chang)時(shi)具有優勢，能節省安裝空(kong)間，簡化補(bu)(bu)(bu)(bu)償(chang)器的安裝。

　　復(fu)式萬向(xiang)鉸鏈膨(peng)脹節包(bao)(bao)括(kuo)兩(liang)個型膨(peng)脹節、中(zhong)(zhong)間(jian)(jian)接(jie)(jie)(jie)(jie)(jie)管和中(zhong)(zhong)間(jian)(jian)連(lian)(lian)(lian)(lian)(lian)接(jie)(jie)(jie)(jie)(jie)板(ban)(ban)等結(jie)構件組(zu)成的撓性裝置;型膨(peng)脹節包(bao)(bao)括(kuo)端管、波紋管、立(li)板(ban)(ban)、鉸鏈板(ban)(ban)、銷軸、環(huan)和連(lian)(lian)(lian)(lian)(lian)接(jie)(jie)(jie)(jie)(jie)板(ban)(ban)支(zhi)(zhi)座(zuo)(zuo)(zuo);中(zhong)(zhong)間(jian)(jian)連(lian)(lian)(lian)(lian)(lian)接(jie)(jie)(jie)(jie)(jie)板(ban)(ban)兩(liang)端通(tong)過連(lian)(lian)(lian)(lian)(lian)接(jie)(jie)(jie)(jie)(jie)板(ban)(ban)銷軸與(yu)(yu)環(huan)連(lian)(lian)(lian)(lian)(lian)接(jie)(jie)(jie)(jie)(jie)在一起;連(lian)(lian)(lian)(lian)(lian)接(jie)(jie)(jie)(jie)(jie)板(ban)(ban)支(zhi)(zhi)座(zuo)(zuo)(zuo)包(bao)(bao)括(kuo)連(lian)(lian)(lian)(lian)(lian)接(jie)(jie)(jie)(jie)(jie)支(zhi)(zhi)承、支(zhi)(zhi)承板(ban)(ban)和卡(ka)板(ban)(ban);連(lian)(lian)(lian)(lian)(lian)接(jie)(jie)(jie)(jie)(jie)支(zhi)(zhi)承固(gu)定(ding)連(lian)(lian)(lian)(lian)(lian)接(jie)(jie)(jie)(jie)(jie)在中(zhong)(zhong)間(jian)(jian)接(jie)(jie)(jie)(jie)(jie)管外(wai)壁中(zhong)(zhong)間(jian)(jian)位(wei)(wei)置，支(zhi)(zhi)承板(ban)(ban)固(gu)定(ding)連(lian)(lian)(lian)(lian)(lian)接(jie)(jie)(jie)(jie)(jie)在連(lian)(lian)(lian)(lian)(lian)接(jie)(jie)(jie)(jie)(jie)支(zhi)(zhi)承外(wai)端面;卡(ka)板(ban)(ban)固(gu)定(ding)連(lian)(lian)(lian)(lian)(lian)接(jie)(jie)(jie)(jie)(jie)在支(zhi)(zhi)承板(ban)(ban)上(shang);中(zhong)(zhong)間(jian)(jian)連(lian)(lian)(lian)(lian)(lian)接(jie)(jie)(jie)(jie)(jie)板(ban)(ban)軸向(xiang)貫(guan)穿卡(ka)板(ban)(ban)上(shang)的通(tong)孔，并(bing)與(yu)(yu)卡(ka)板(ban)(ban)上(shang)的通(tong)孔間(jian)(jian)隙配(pei)合(he)，構成浮動連(lian)(lian)(lian)(lian)(lian)接(jie)(jie)(jie)(jie)(jie)結(jie)構;進一步改進在于：連(lian)(lian)(lian)(lian)(lian)接(jie)(jie)(jie)(jie)(jie)板(ban)(ban)支(zhi)(zhi)座(zuo)(zuo)(zuo)上(shang)卡(ka)板(ban)(ban)側邊還(huan)設有限(xian)(xian)位(wei)(wei)塊;中(zhong)(zhong)間(jian)(jian)連(lian)(lian)(lian)(lian)(lian)接(jie)(jie)(jie)(jie)(jie)板(ban)(ban)卡(ka)合(he)在限(xian)(xian)位(wei)(wei)塊上(shang)開(kai)口槽內(nei)，與(yu)(yu)開(kai)口槽間(jian)(jian)隙配(pei)合(he)。

　　鉸鏈型補償器(qi)一般以兩個(ge)或三個(ge)作為一組使用(yong)，用(yong)于吸(xi)收(shou)單(dan)平(ping)面(mian)(mian)管系(xi)中一個(ge)或多個(ge)方面(mian)(mian)的(de)橫向位移。在系(xi)統中每(mei)一個(ge)補償器(qi)受它的(de)鉸鏈所制約，產生鈍角位移。在管系(xi)中每(mei)對鉸鏈式(shi)補償器(qi)互相配合，能夠形成(cheng)單(dan)平(ping)面(mian)(mian)管系(xi)中的(de)擺動式(shi)以吸(xi)收(shou)橫向位移。

　　每對鉸(jiao)鏈(lian)式(shi)補償器(qi)所(suo)能吸收的橫向位移與其鉸(jiao)鏈(lian)銷軸之間的距離成(cheng)正比。因此，為了使補償器(qi)充分發揮效(xiao)用，應盡量加大這一距離。

　　角向(xiang)型波紋補償器中的鉸鏈組(zu)件主要(yao)用(yong)于承(cheng)受(shou)管(guan)道(dao)因(yin)內壓力(li)(li)(li)(li)(li)產(chan)生的推力(li)(li)(li)(li)(li)，也可(ke)用(yong)于承(cheng)擔管(guan)道(dao)和設備的重(zhong)(zhong)量、風載或類(lei)似的外力(li)(li)(li)(li)(li)。不僅能夠(gou)吸收任(ren)一(yi)平面內的橫(heng)向(xiang)位移，而且能承(cheng)受(shou)波紋管(guan)壓力(li)(li)(li)(li)(li)推力(li)(li)(li)(li)(li)。另外，也可(ke)以用(yong)來承(cheng)受(shou)管(guan)道(dao)和設備的重(zhong)(zhong)量、風載。

　　六，安裝方(fang)法與(yu)使用(yong)案例

　　角向型(xing)波紋補償器(J型(xing))

　　這類波(bo)紋補償(chang)器(qi)(qi)結構緊(jin)湊、應用(yong)靈活、安裝(zhuang)方便、對(dui)支座(zuo)無壓力(li)推(tui)力(li)作(zuo)用(yong)。由于單式角向(xiang)波(bo)紋補償(chang)器(qi)(qi)只能作(zuo)角偏轉,因(yin)此均為(wei)二(er)個以上(shang)配套使用(yong)。

　　用一(yi)對角(jiao)向(xiang)(xiang)型波紋(wen)補償器吸收(shou)橫向(xiang)(xiang)位(wei)(wei)移(yi)時,角(jiao)位(wei)(wei)移(yi)量一(yi)定,其所能(neng)吸收(shou)的橫向(xiang)(xiang)位(wei)(wei)移(yi)量與兩(liang)波紋(wen)補償器之(zhi)間(jian)的距離成正比,應盡(jin)可(ke)能(neng)地(di)加大兩(liang)波紋(wen)補償器之(zhi)間(jian)的距離,可(ke)以更有效發揮其補償作用。

　　在(zai)此(ci)以角向型波(bo)紋補償器為例(li),說明其應(ying)用的場合(he),見圖(tu)10～圖(tu)13。
