虹吸式坐便器技術現狀

虹(hong)(hong)吸(xi)(xi)(xi)(xi)(xi)式(shi)(shi)坐(zuo)(zuo)(zuo)(zuo)(zuo)便(bian)器(qi)(qi)(qi)排(pai)(pai)(pai)水(shui)(shui)原理：在(zai)水(shui)(shui)箱(xiang)放水(shui)(shui)后，靠水(shui)(shui)自(zi)身(shen)的(de)(de)(de)重力作用(yong)(yong)，水(shui)(shui)流瞬(shun)(shun)間到達坐(zuo)(zuo)(zuo)(zuo)(zuo)便(bian)器(qi)(qi)(qi)的(de)(de)(de)水(shui)(shui)圈和洗凈面，使(shi)水(shui)(shui)流旋(xuan)轉起來(lai)形(xing)成旋(xuan)渦，同時也使(shi)污物(wu)旋(xuan)轉并將(jiang)其打碎，隨著水(shui)(shui)位的(de)(de)(de)升高(gao)，瞬(shun)(shun)間將(jiang)排(pai)(pai)(pai)污管(guan)(guan)道(dao)(dao)內填(tian)充滿。再(zai)通(tong)過大(da)氣壓和水(shui)(shui)的(de)(de)(de)勢能差使(shi)坐(zuo)(zuo)(zuo)(zuo)(zuo)便(bian)器(qi)(qi)(qi)瞬(shun)(shun)間產(chan)生(sheng)自(zi)然(ran)虹(hong)(hong)吸(xi)(xi)(xi)(xi)(xi)作用(yong)(yong)，將(jiang)污物(wu)排(pai)(pai)(pai)入(吸(xi)(xi)(xi)(xi)(xi)入)S型(xing)(xing)管(guan)(guan)道(dao)(dao)中，用(yong)(yong)后續水(shui)(shui)沖(chong)出(chu)坐(zuo)(zuo)(zuo)(zuo)(zuo)便(bian)器(qi)(qi)(qi)而(er)排(pai)(pai)(pai)到下水(shui)(shui)管(guan)(guan)中。由(you)此可見(jian)，虹(hong)(hong)吸(xi)(xi)(xi)(xi)(xi)式(shi)(shi)坐(zuo)(zuo)(zuo)(zuo)(zuo)便(bian)器(qi)(qi)(qi)實際上是(shi)(shi)一個排(pai)(pai)(pai)水(shui)(shui)凈化機構，它的(de)(de)(de)這種作用(yong)(yong)是(shi)(shi)客觀(guan)(guan)存在(zai)的(de)(de)(de)。只要(yao)滿足以上條(tiao)件，這種自(zi)然(ran)虹(hong)(hong)吸(xi)(xi)(xi)(xi)(xi)作用(yong)(yong)就會產(chan)生(sheng)。S管(guan)(guan)道(dao)(dao)是(shi)(shi)虹(hong)(hong)吸(xi)(xi)(xi)(xi)(xi)式(shi)(shi)坐(zuo)(zuo)(zuo)(zuo)(zuo)便(bian)器(qi)(qi)(qi)產(chan)生(sheng)自(zi)然(ran)虹(hong)(hong)吸(xi)(xi)(xi)(xi)(xi)作用(yong)(yong)的(de)(de)(de)關鍵部(bu)件。由(you)于其結(jie)(jie)構的(de)(de)(de)性，該(gai)坐(zuo)(zuo)(zuo)(zuo)(zuo)便(bian)器(qi)(qi)(qi)的(de)(de)(de)安裝尺(chi)距(坑距)一般為200mm，305mm，400mm。虹(hong)(hong)吸(xi)(xi)(xi)(xi)(xi)式(shi)(shi)坐(zuo)(zuo)(zuo)(zuo)(zuo)便(bian)器(qi)(qi)(qi)按外觀(guan)(guan)可分(fen)為，分(fen)體式(shi)(shi)、連體式(shi)(shi)，管(guan)(guan)道(dao)(dao)有外露型(xing)(xing)和隱藏(zang)型(xing)(xing)。管(guan)(guan)道(dao)(dao)外露型(xing)(xing)的(de)(de)(de)虹(hong)(hong)吸(xi)(xi)(xi)(xi)(xi)式(shi)(shi)坐(zuo)(zuo)(zuo)(zuo)(zuo)便(bian)器(qi)(qi)(qi)(分(fen)體式(shi)(shi)坐(zuo)(zuo)(zuo)(zuo)(zuo)便(bian))目(mu)前在(zai)市(shi)場(chang)上占(zhan)主流，原因是(shi)(shi)這種坐(zuo)(zuo)(zuo)(zuo)(zuo)便(bian)器(qi)(qi)(qi)比較適(shi)合(he)采(cai)用(yong)(yong)一次(ci)成形(xing)組合(he)立式(shi)(shi)澆(jiao)注(zhu)工藝，但這種坐(zuo)(zuo)(zuo)(zuo)(zuo)便(bian)器(qi)(qi)(qi)在(zai)使(shi)用(yong)(yong)中不(bu)易清(qing)潔(jie)；而(er)管(guan)(guan)道(dao)(dao)隱藏(zang)型(xing)(xing)的(de)(de)(de)虹(hong)(hong)吸(xi)(xi)(xi)(xi)(xi)式(shi)(shi)坐(zuo)(zuo)(zuo)(zuo)(zuo)便(bian)器(qi)(qi)(qi)一般采(cai)用(yong)(yong)地攤多塊澆(jiao)注(zhu)粘(zhan)接成形(xing)，這種坐(zuo)(zuo)(zuo)(zuo)(zuo)便(bian)器(qi)(qi)(qi)在(zai)使(shi)用(yong)(yong)中容易進(jin)(jin)行清(qing)潔(jie)，外形(xing)美觀(guan)(guan)，目(mu)前這種坐(zuo)(zuo)(zuo)(zuo)(zuo)便(bian)器(qi)(qi)(qi)在(zai)市(shi)場(chang)上以全(quan)包(bao)連體占(zhan)主流。來(lai)，虹(hong)(hong)吸(xi)(xi)(xi)(xi)(xi)式(shi)(shi)坐(zuo)(zuo)(zuo)(zuo)(zuo)便(bian)器(qi)(qi)(qi)不(bu)斷改進(jin)(jin)和發展，其結(jie)(jie)構形(xing)式(shi)(shi)從(cong)單一的(de)(de)(de)普通(tong)虹(hong)(hong)吸(xi)(xi)(xi)(xi)(xi)式(shi)(shi)己經衍生(sheng)出(chu)噴(pen)射(she)虹(hong)(hong)吸(xi)(xi)(xi)(xi)(xi)式(shi)(shi)和旋(xuan)渦虹(hong)(hong)吸(xi)(xi)(xi)(xi)(xi)式(shi)(shi)。

普通(tong)虹吸式(shi)(shi)坐(zuo)便器產(chan)(chan)(chan)生得較早，生產(chan)(chan)(chan)歷(li)史較長(chang)，結構(gou)也比較常見，目前(qian)在市場(chang)上的(de)型(xing)號、種(zhong)類(lei)也比較多。它是(shi)新型(xing)虹吸式(shi)(shi)坐(zuo)便器的(de)基礎(chu)。20世紀(ji)七、八十年代，坐(zuo)便器的(de)品種(zhong)少，成(cheng)(cheng)(cheng)(cheng)形(xing)生產(chan)(chan)(chan)工藝方式(shi)(shi)落后，為(wei)(wei)地(di)攤(tan)(tan)單面(mian)吸漿多塊(kuai)粘接(jie)(jie)成(cheng)(cheng)(cheng)(cheng)形(xing)生產(chan)(chan)(chan)，包括排(pai)污(wu)管道也是(shi)粘接(jie)(jie)的(de)。占地(di)面(mian)積大，生產(chan)(chan)(chan)效率低，產(chan)(chan)(chan)品質量(liang)(liang)差，排(pai)水(shui)(shui)(shui)(shui)(shui)(shui)功能也不理想。近20年來，隨(sui)著衛(wei)生陶瓷行(xing)業的(de)發(fa)展(zhan)和模型(xing)制作工藝技術的(de)不斷(duan)進(jin)步，無(wu)論是(shi)該產(chan)(chan)(chan)品的(de)結構(gou)還是(shi)成(cheng)(cheng)(cheng)(cheng)形(xing)生產(chan)(chan)(chan)工藝方式(shi)(shi)都發(fa)生了(le)巨大變化，即使(shi)是(shi)現(xian)在的(de)地(di)攤(tan)(tan)成(cheng)(cheng)(cheng)(cheng)形(xing)，該產(chan)(chan)(chan)品也可以是(shi)整體一(yi)次成(cheng)(cheng)(cheng)(cheng)形(xing)或兩塊(kuai)粘接(jie)(jie)成(cheng)(cheng)(cheng)(cheng)形(xing)，且產(chan)(chan)(chan)量(liang)(liang)提(ti)高一(yi)倍；大多數企業現(xian)在廣泛采用(yong)組合立(li)式(shi)(shi)澆注一(yi)次成(cheng)(cheng)(cheng)(cheng)形(xing)機械化生產(chan)(chan)(chan)，產(chan)(chan)(chan)量(liang)(liang)提(ti)高近2倍，坐(zuo)便器的(de)排(pai)污(wu)功能和節水(shui)(shui)(shui)(shui)(shui)(shui)功能也不斷(duan)提(ti)高。普通(tong)虹吸式(shi)(shi)排(pai)水(shui)(shui)(shui)(shui)(shui)(shui)水(shui)(shui)(shui)(shui)(shui)(shui)路走向為(wei)(wei)：水(shui)(shui)(shui)(shui)(shui)(shui)箱放(fang)水(shui)(shui)(shui)(shui)(shui)(shui)、便器進(jin)水(shui)(shui)(shui)(shui)(shui)(shui)口(kou)、進(jin)水(shui)(shui)(shui)(shui)(shui)(shui)橫(heng)道、水(shui)(shui)(shui)(shui)(shui)(shui)圈(quan)、布水(shui)(shui)(shui)(shui)(shui)(shui)眼(yan)、洗凈面(mian)、S型(xing)管道、排(pai)污(wu)口(kou)。

坐(zuo)便器(qi)(qi)的(de)(de)作用是將(jiang)便器(qi)(qi)洗凈面壁的(de)(de)污(wu)物(wu)(wu)沖刷干(gan)凈；將(jiang)固體污(wu)物(wu)(wu)打碎，盡快將(jiang)便器(qi)(qi)內的(de)(de)污(wu)物(wu)(wu)排(pai)(pai)出。要達到(dao)以(yi)上目的(de)(de)，排(pai)(pai)水(shui)(shui)(shui)(shui)水(shui)(shui)(shui)(shui)流(liu)(liu)   旋(xuan)轉(zhuan)起來(lai)，這是大多數坐(zuo)便器(qi)(qi)水(shui)(shui)(shui)(shui)流(liu)(liu)設(she)計為旋(xuan)轉(zhuan)式的(de)(de)主(zhu)要原因(布(bu)(bu)(bu)水(shui)(shui)(shui)(shui)眼旋(xuan)轉(zhuan)比直(zhi)沖沖刷效果好(hao))。虹吸(xi)式坐(zuo)便器(qi)(qi)的(de)(de)布(bu)(bu)(bu)水(shui)(shui)(shui)(shui)眼設(she)計也遵循(xun)這一規律(lv)，這是虹吸(xi)式坐(zuo)便器(qi)(qi)的(de)(de)顯著特(te)點。布(bu)(bu)(bu)水(shui)(shui)(shui)(shui)眼設(she)計成   角(jiao)度和斜度，一般角(jiao)度為300~450。排(pai)(pai)水(shui)(shui)(shui)(shui)時從(cong)布(bu)(bu)(bu)水(shui)(shui)(shui)(shui)眼流(liu)(liu)出的(de)(de)水(shui)(shui)(shui)(shui)在對(dui)內壁沖刷的(de)(de)同時，也推(tui)動(dong)水(shui)(shui)(shui)(shui)封水(shui)(shui)(shui)(shui)，以(yi)使(shi)水(shui)(shui)(shui)(shui)流(liu)(liu)旋(xuan)轉(zhuan)(逆時針或順時針)起來(lai)形成旋(xuan)渦(wo)。普通(tong)虹吸(xi)式坐(zuo)便器(qi)(qi)在布(bu)(bu)(bu)水(shui)(shui)(shui)(shui)眼設(she)計上還要有大孔—長形孔(尺寸為15mmx60mm)或數量若干(gan)的(de)(de)大孔(直(zhi)徑(jing)為15一18mm)。大孔通(tong)常在正面中間部位，個(ge)別孔分布(bu)(bu)(bu)在兩(liang)側，目的(de)(de)是對(dui)準污(wu)物(wu)(wu)加大沖力，加強旋(xuan)轉(zhuan)，使(shi)其盡早產生虹吸(xi)作用，同時將(jiang)污(wu)物(wu)(wu)打碎，將(jiang)其推(tui)向S型(xing)管道和排(pai)(pai)污(wu)口，排(pai)(pai)入下水(shui)(shui)(shui)(shui)管道。有旋(xuan)渦(wo)旋(xuan)轉(zhuan)的(de)(de)水(shui)(shui)(shui)(shui)流(liu)(liu)對(dui)排(pai)(pai)出質量較(jiao)(jiao)輕的(de)(de)檢測介質，如直(zhi)徑(jing)為19mm的(de)(de)聚(ju)丙(bing)烯測試球(qiu)體、煙絲、鋸末或乒乓球(qiu)等(deng)漂浮物(wu)(wu)較(jiao)(jiao)為有利(li)。但(dan)這種排(pai)(pai)水(shui)(shui)(shui)(shui)結構(gou)和布(bu)(bu)(bu)水(shui)(shui)(shui)(shui)眼的(de)(de)設(she)計對(dui)排(pai)(pai)出質量較(jiao)(jiao)重(zhong)的(de)(de)污(wu)物(wu)(wu)效果欠佳(jia)。
