派(pai)克漢尼汾公司進入中國(guo)市場的(de)時間(jian)不久,但由(you)于高(gao)性(xing)價比的(de)產品和優質的(de)售前售后服務,在中國(guo)很多大(da)型項目上已(yi)經展露頭角,產品以其高(gao)品質、高(gao)性(xing)能、高(gao)科技等全面的(de)進入中國(guo)工業的(de)各個領域,從(cong)航空航天領域、到CRH項目、到冶金鋼鐵及鋁(lv)業都可(ke)以看到Parker的(de)身影。 派克減壓閥是靠閥內流道對(dui)水(shui)(shui)流的(de)局部(bu)阻力降低水(shui)(shui)壓,水(shui)(shui)壓降的(de)范圍由(you)連接閥瓣的(de)薄膜或活 塞兩側的進(jin)出口水(shui)壓(ya)(ya)差(cha)自動調節。定比(bi)減壓(ya)(ya)原理是利用閥體中浮動活塞的水(shui)壓(ya)(ya)比(bi)控制,進(jin)出口 端(duan)減(jian)壓比與進出口側活塞面積比成反比。這種減(jian)壓閥工作(zuo)平穩無(wu)振動;閥體內無(wu)彈(dan)簧,故無(wu)彈(dan) 簧(huang)銹蝕(shi)、金屬(shu)疲勞失效之慮;密封性能良好不滲漏(lou),因而(er)既減(jian)動壓(水流動時)又減(jian)靜壓(流 量為0時);特別(bie)是在減壓的同(tong)時不影(ying)響水(shui)流(liu)量。 進口派克減壓閥運行操作注意事(shi)項: 1.要避免存留臟物、雜(za)物進(jin)入(ru)減(jian)(jian)壓(ya)(ya)閥(fa)(fa)減(jian)(jian)壓(ya)(ya)保障(zhang)系(xi)(xi)統(tong)。新建或(huo)者改造工(gong)(gong)程的(de)(de)減(jian)(jian)壓(ya)(ya)系(xi)(xi)統(tong)管網,很可能(neng)遺留沙粒、麻絲、雜(za)物。投運前,一(yi)(yi)般(ban)都應(ying)進(jin)行水沖洗(xi),滿(man)足清(qing)潔(jie)要求(qiu)后,后裝(zhuang)上減(jian)(jian)壓(ya)(ya)閥(fa)(fa)和(he)過(guo)濾(lv)(lv)器(qi)(qi)(qi)濾(lv)(lv)芯(xin),這樣才能(neng)避免雜(za)物流入(ru)減(jian)(jian)壓(ya)(ya)閥(fa)(fa),杜絕減(jian)(jian)壓(ya)(ya)閥(fa)(fa)卡芯(xin)現象。在(zai)系(xi)(xi)統(tong)進(jin)入(ru)工(gong)(gong)作(zuo)后,保障(zhang)減(jian)(jian)壓(ya)(ya)系(xi)(xi)統(tong)的(de)(de)水流暢通與否,與設置在(zai)系(xi)(xi)統(tong)上的(de)(de)過(guo)濾(lv)(lv)器(qi)(qi)(qi)流通能(neng)力(li)關系(xi)(xi)密(mi)切,如濾(lv)(lv)芯(xin)被雜(za)物嚴重吸附,則會(hui)影響減(jian)(jian)壓(ya)(ya)閥(fa)(fa)的(de)(de)工(gong)(gong)作(zuo),為此必需(xu)對過(guo)濾(lv)(lv)器(qi)(qi)(qi)進(jin)行定期檢(jian)查,及時清(qing)除污穢。實踐表明這項工(gong)(gong)作(zuo)2至3個月必須進(jin)行一(yi)(yi)次,有(you)些可調式(彈簧式、薄膜式)減(jian)(jian)壓(ya)(ya)閥(fa)(fa),其主閥(fa)(fa)或(huo)者導閥(fa)(fa)自身設置過(guo)濾(lv)(lv)器(qi)(qi)(qi),同樣需(xu)要定期拆洗(xi)濾(lv)(lv)芯(xin)。 2.1用1備(bei)的減(jian)(jian)壓(ya)(ya)閥(fa)(fa)組(zu)應定期輪換工(gong)作。大部分高層建筑(zhu)生活給(gei)(gei)水(shui)減(jian)(jian)壓(ya)(ya)閥(fa)(fa)減(jian)(jian)壓(ya)(ya)保障系統(tong),是以給(gei)(gei)水(shui)豎(shu)向分區(qu)(qu)設(she)置(zhi)的,一(yi)(yi)般設(she)在每(mei)一(yi)(yi)給(gei)(gei)水(shui)分區(qu)(qu)總管(guan)上(shang)。考(kao)慮(lv)到眾多用戶的用水(shui)可靠安全(quan)性(住宅每(mei)一(yi)(yi)分區(qu)(qu)有幾(ji)十戶至(zhi)上(shang)百戶,公共建筑(zhu)如賓(bin)館、飯店,每(mei)一(yi)(yi)分區(qu)(qu)有幾(ji)十套(tao)(tao)客房……),設(she)計時(shi)減(jian)(jian)壓(ya)(ya)閥(fa)(fa)應兩(liang)套(tao)(tao)并列安裝(1用1備(bei))。減(jian)(jian)壓(ya)(ya)通(tong)(tong)(tong)路(lu)兩(liang)側都(dou)輔以閘閥(fa)(fa)或蝶(die)閥(fa)(fa),可啟閉任一(yi)(yi)減(jian)(jian)壓(ya)(ya)通(tong)(tong)(tong)道,為使(shi)并列的兩(liang)套(tao)(tao)減(jian)(jian)壓(ya)(ya)閥(fa)(fa)通(tong)(tong)(tong)道能(neng)正(zheng)常工(gong)作,常規一(yi)(yi)個(ge)月(yue)輪流交換一(yi)(yi)次,擱置(zhi)時(shi)間過長減(jian)(jian)壓(ya)(ya)通(tong)(tong)(tong)道死水(shui)結垢,減(jian)(jian)壓(ya)(ya)元(yuan)件閥(fa)(fa)芯會卡住失效。 3.應(ying)(ying)及時(shi)排(pai)除管(guan)道中(zhong)的積氣。當空(kong)氣進(jin)(jin)入(ru)減(jian)壓(ya)(ya)管(guan)網或管(guan)網內(nei)隨壓(ya)(ya)力變(bian)(bian)化時(shi)氣體(ti)從水(shui)(shui)(shui)(shui)中(zhong)析出(chu)(chu),這(zhe)(zhe)(zhe)時(shi)區域內(nei)用(yong)戶的水(shui)(shui)(shui)(shui)壓(ya)(ya)極不穩定;處在(zai)(zai)供水(shui)(shui)(shui)(shui)不利點(dian)用(yong)水(shui)(shui)(shui)(shui)器(qi)更是壓(ya)(ya)力變(bian)(bian)化急驟,有(you)(you)時(shi)呈現(xian)(xian)虛假的峰值壓(ya)(ya)力,有(you)(you)時(shi)還會(hui)抽吸斷水(shui)(shui)(shui)(shui),還有(you)(you)管(guan)網會(hui)伴(ban)隨撞擊(ji)聲。產生這(zhe)(zhe)(zhe)種(zhong)現(xian)(xian)象,會(hui)影響(xiang)燃氣熱(re)水(shui)(shui)(shui)(shui)器(qi)、電熱(re)水(shui)(shui)(shui)(shui)器(qi)等(deng)穩定工作,嚴重時(shi)會(hui)被(bei)毀(hui)壞;對各(ge)種(zhong)盥洗器(qi)具的進(jin)(jin)水(shui)(shui)(shui)(shui)連接管(guan)破(po)壞力也很大,因(yin)此(ci)爆(bao)管(guan)的事件(jian)屢有(you)(you)發生;有(you)(you)些水(shui)(shui)(shui)(shui)表無法(fa)正確計量,出(chu)(chu)現(xian)(xian)用(yong)戶不用(yong)水(shui)(shui)(shui)(shui),水(shui)(shui)(shui)(shui)表也會(hui)不斷地轉動。為(wei)杜絕(jue)這(zhe)(zhe)(zhe)類事故(gu),應(ying)(ying)檢查屋頂(ding)水(shui)(shui)(shui)(shui)箱(xiang)生活給水(shui)(shui)(shui)(shui)總管(guan)的蓄水(shui)(shui)(shui)(shui)高程(cheng)是否滿足,如不滿足水(shui)(shui)(shui)(shui)箱(xiang)出(chu)(chu)水(shui)(shui)(shui)(shui)口處會(hui)產生水(shui)(shui)(shui)(shui)旋,吸入(ru)空(kong)氣。排(pai)除這(zhe)(zhe)(zhe)一(yi)故(gu)障可(ke)(ke)調(diao)整水(shui)(shui)(shui)(shui)箱(xiang)內(nei)液位(wei)(wei)控(kong)制器(qi)的低水(shui)(shui)(shui)(shui)位(wei)(wei)高程(cheng),經(jing)驗表明一(yi)般低水(shui)(shui)(shui)(shui)位(wei)(wei)距出(chu)(chu)水(shui)(shui)(shui)(shui)口應(ying)(ying)不小于0.3m。也可(ke)(ke)反復開啟(qi)設(she)置(zhi)在(zai)(zai)分區、減(jian)壓(ya)(ya)系統兩側的壓(ya)(ya)力表放氣旋塞,把已進(jin)(jin)入(ru)管(guan)網內(nei)的空(kong)氣徐徐排(pai)出(chu)(chu)。如采取上述措施后,在(zai)(zai)分區總管(guan)末梢以(yi)下的一(yi)些用(yong)水(shui)(shui)(shui)(shui)器(qi)還出(chu)(chu)現(xian)(xian)上述現(xian)(xian)象,可(ke)(ke)以(yi)在(zai)(zai)這(zhe)(zhe)(zhe)些部(bu)位(wei)(wei)增設(she)自動排(pai)氣裝置(zhi)。 4.注(zhu)意(yi)(yi)減(jian)壓(ya)(ya)閥(fa)(fa)的減(jian)壓(ya)(ya)保障系統。無論選用(yong)比例式還是可調(diao)式減(jian)壓(ya)(ya)閥(fa)(fa),其減(jian)壓(ya)(ya)比P1∶P2不宜選擇過大,一般應控制在(zai)5∶1之內。超過這個范圍易(yi)產(chan)生氣(qi)蝕現象,損壞閥(fa)(fa)件,產(chan)生嘯叫噪音。有些活塞式減(jian)壓(ya)(ya)閥(fa)(fa),制造(zao)廠在(zai)其閥(fa)(fa)體(ti)上(shang)加工一個直徑1.5mm左右的小孔,其功能是讓(rang)閥(fa)(fa)芯運動(dong)時起到透吸氣(qi)作用(yong),維護管理時應注(zhu)意(yi)(yi)千萬不要將小孔塞住,否(fou)則影響減(jian)壓(ya)(ya)閥(fa)(fa)的正常運行。 5.加(jia)強(qiang)減壓閥(fa)保障(zhang)系統的(de)管理xun視,要注意觀察減(jian)壓(ya)(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)(fa)(fa)本身(shen)的(de)(de)工作(zuo)動態。閥(fa)(fa)(fa)(fa)(fa)前、閥(fa)(fa)(fa)(fa)(fa)后壓(ya)(ya)(ya)(ya)(ya)力數值(zhi)接近(jin),表明減(jian)壓(ya)(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)(fa)(fa)本身(shen)已(yi)存(cun)在(zai)故(gu)障。即活(huo)(huo)塞(sai)(sai)式(shi)減(jian)壓(ya)(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)(fa)(fa)的(de)(de)閥(fa)(fa)(fa)(fa)(fa)芯與閥(fa)(fa)(fa)(fa)(fa)體間的(de)(de)平面密(mi)封橡膠件(jian)損壞(huai)(huai);薄膜式(shi)可(ke)調型減(jian)壓(ya)(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)(fa)(fa)主閥(fa)(fa)(fa)(fa)(fa)膜片有(you)裂痕(hen)和O型圈損壞(huai)(huai),及(ji)導閥(fa)(fa)(fa)(fa)(fa)連通管堵塞(sai)(sai),造成減(jian)壓(ya)(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)(fa)(fa)減(jian)壓(ya)(ya)(ya)(ya)(ya)作(zuo)用(yong)削弱或者失效。這對(dui)分區管網危害極(ji)大,特別是(shi)許(xu)多用(yong)水設備可(ke)能因超壓(ya)(ya)(ya)(ya)(ya)力而(er)出現爆管,必須及(ji)時(shi)修(xiu)復(fu)。比例式(shi)(活(huo)(huo)塞(sai)(sai)型)減(jian)壓(ya)(ya)(ya)(ya)(ya)閥(fa)(fa)(fa)(fa)(fa)閥(fa)(fa)(fa)(fa)(fa)體上(shang)的(de)(de)透吸(xi)氣小孔如出現滴漏不止(zhi),表明閥(fa)(fa)(fa)(fa)(fa)芯上(shang)幾(ji)檔(dang)O型密(mi)封圈已(yi)經(jing)磨損,要更換密(mi)封件(jian)。但(dan)在(zai)修(xiu)理拆裝減(jian)壓(ya)(ya)(ya)(ya)(ya)元件(jian)時(shi),要謹慎(shen)細心,調換內(nei)密(mi)封件(jian);清理雜(za)物時(shi),應因勢利導,不要用(yong)金(jin)屬棒、硬梗撬閥(fa)(fa)(fa)(fa)(fa)的(de)(de)活(huo)(huo)動部位,使(shi)用(yong)木榔頭和木柄(bing)敲擊震動,慢慢拆卸閥(fa)(fa)(fa)(fa)(fa)內(nei)部件(jian)。修(xiu)理完畢后重新(xin)安裝時(shi),一定要和閥(fa)(fa)(fa)(fa)(fa)門上(shang)的(de)(de)流向指示保持*。 6.注意檢查比例式(shi)減(jian)(jian)壓(ya)(ya)(ya)閥(fa)的(de)安(an)裝位(wei)置(zhi)(zhi)。高(gao)層內減(jian)(jian)壓(ya)(ya)(ya)閥(fa)設計安(an)裝的(de)位(wei)置(zhi)(zhi)不(bu)妥,會出現(xian)減(jian)(jian)壓(ya)(ya)(ya)閥(fa)閥(fa)后(hou)壓(ya)(ya)(ya)力忽高(gao)忽低,管(guan)(guan)網壓(ya)(ya)(ya)力嚴重偏離允許范圍,伴隨毀壞淋浴器(qi),水(shui)管(guan)(guan)爆裂和(he)損(sun)壞用戶(hu)水(shui)表等事(shi)故(gu)(gu)發(fa)生;有時也會水(shui)流不(bu)暢,分(fen)區(qu)內出現(xian)無(wu)規律的(de)斷(duan)水(shui)現(xian)象(xiang),影響(xiang)用戶(hu)用水(shui)。出現(xian)類似事(shi)故(gu)(gu),檢查整個(ge)減(jian)(jian)壓(ya)(ya)(ya)閥(fa)減(jian)(jian)壓(ya)(ya)(ya)分(fen)區(qu)給水(shui)系統,無(wu)疑點可找;拆卸減(jian)(jian)壓(ya)(ya)(ya)閥(fa)過濾(lv)器(qi)等元件并無(wu)異常;有些物業管(guan)(guan)理(li)單位(wei)甚至懷疑減(jian)(jian)壓(ya)(ya)(ya)閥(fa)的(de)技術性能(neng)(neng),多次(ci)調換新的(de)減(jian)(jian)壓(ya)(ya)(ya)閥(fa),也不(bu)能(neng)(neng)解(jie)決(jue)問題。這時可從檢查比例減(jian)(jian)壓(ya)(ya)(ya)閥(fa)設計安(an)裝位(wei)置(zhi)(zhi)是否合理(li)著手,認真檢查管(guan)(guan)網系統是否存在(zai)等位(wei)倒虹管(guan)(guan)現(xian)象(xiang),即(ji)分(fen)區(qu)的(de)輸出管(guan)(guan)路標高(gao)相近(jin)。
