Mangaphi amanyathelo okhuseleko owaziyo xa ufaka iivalvu? Amanqaku okuqwalaselwa ekusetyenzisweni kwevalve ye-fluorine efakwe kwiplastiki ye-anticorrosive Xa ivalve ifakwe, ukuze kuthintelwe isinyithi, isanti kunye namanye amaqumrhu angaphandle ukuba angangeni kwivalve kwaye wonakalise umphezulu wokutywina, kuyimfuneko ukuseta isihluzo kunye nevalve yokugungxula; Ukuze kugcinwe ukuhlanjululwa komoya ocinezelweyo, phambi kwevalve kufuneka ubeke i-oil-water separator, okanye i-air filter; Ukujonga imeko yokusebenza yevalve ngexesha lokusebenza, kuyimfuneko ukuseta isixhobo kwaye ujonge i-valve; Ukuze kugcinwe ukushisa okusebenzayo, faka i-insulation ngaphandle kwevalve; Ukufakwa kwe-valve ye-post-valve, i-valve yokukhulula okanye i-valve yokukhangela ...... iyadingeka Xa i-valve ifakwe, ukwenzela ukukhusela isinyithi, isanti kunye nezinye imizimba yangaphandle ekuhlaseleni i-valve kwaye yonakalise indawo yokutywina, kuyimfuneko. ukuseta isihluzo kunye nevalve yokugungxula; Ukuze kugcinwe ukuhlanjululwa komoya ocinezelweyo, phambi kwevalve kufuneka ubeke i-oil-water separator, okanye i-air filter; Ukujonga imeko yokusebenza yevalve ngexesha lokusebenza, kuyimfuneko ukuseta isixhobo kwaye ujonge i-valve; Ukuze kugcinwe ukushisa okusebenzayo, faka i-insulation ngaphandle kwevalve; Ufakelo emva kwevalve, kufuneka umise ivalve yokhuseleko okanye ivalve yokukhangela; Ukuqwalasela ukusebenza okuqhubekayo kwe-valve, ekulungele ingozi, ukumisela inkqubo ehambelanayo okanye inkqubo yokudlula. 1. Izixhobo ezikhuselayo zokukhusela i-valve yokutshekisha: Ukuthintela ukuvuza kwee-valve zokutshekisha okanye ukubuya kweendaba emva kokungaphumeleli, okubangelwa ukuthotywa komgangatho wemveliso kunye neengozi, i-valve enye okanye ezimbini ezinqamlekileyo zisetwa ngaphambi nangemva kwe-valve yokukhangela. Ukuba iivalve ezimbini zokuvala zibonelelwe, ivalve yokutshekisha inokususwa ngokulula kwinkonzo. Izixhobo zokukhusela i-valve ye-2 yokhuseleko: ngaphambi nangemva kwendlela yokufakela ngokuqhelekileyo ayisetyenzisi i-valve yebhloko, kuphela kwiimeko zomntu ngamnye, zingasetyenziswa. Ukuba amandla aphakathi aqulethe amasuntswana aqinileyo, achaphazela ivalve yokhuseleko ayinakuvalwa emva kokusuka, ukufaka ivalve yesango etywiniweyo ngaphambi nangemva kwevalve yokhuseleko, ivalve yesango kufuneka ibekwimeko evuleke ngokupheleleyo, ivalve yesango. kunye nevalve yokhuseleko ixhotyiswe ngokuthe ngqo ngevalve yokuhlola i-DN20 emoyeni. Xa isiqabu se-wax kunye nezinye imidiya kwiqondo lobushushu begumbi lemeko eqinileyo, okanye ukunciphisa uxinzelelo lwegesi kunye nolwelo olulula oluphakathi lobushushu obungaphantsi kwe-0 degrees Celsius, ivalve yokhuseleko ifuna ubushushu bomphunga. Ivalve yokhuseleko kumajelo eendaba ezonakalisayo, ngokuxhomekeke ekuxhathiseni umhlwa kwevalve, cinga ukongeza ifilimu ekwaziyo ukumelana nokudubula kwindawo yevalve. Ivalve yokhuseleko lwerhasi ngokuqhelekileyo ibonelelwa ngevalve edlulayo ngokobungakanani bayo, njenge-vent manual. 3. Izixhobo zokukhusela iivalve zokunciphisa uxinzelelo: ngokuqhelekileyo kukho iintlobo ezintathu zeendawo zokufakela iivalve zokunciphisa uxinzelelo. Iigeyiji zoxinzelelo zifakwe ngaphambi nangemva kwevalve yokunciphisa ukuququzelela ukubonwa koxinzelelo ngaphambi nangemva kwevalve. Kukho i-valve ekhuselekileyo yokhuseleko evalelekileyo emva kwevalve ukukhusela ukungaphumeleli kwe-valve yokunciphisa uxinzelelo, i-valve emva koxinzelelo lugqithise uxinzelelo oluqhelekileyo xa ugxuma, kuquka i-valve emva kwenkqubo. Umbhobho we-drain ufakwe phambi kwevalve ukunqumla i-valve, umsebenzi oyintloko kukukhupha umlambo, abanye basebenzisa umgibe. Umsebenzi oyintloko wombhobho we-bypass kuxa ukusilela kwevalve yokunciphisa uxinzelelo, vala ivalve yokunciphisa uxinzelelo ngaphambi nangemva kwevalve yokunqunyulwa, vula ivalve ye-bypass, lungisa ngesandla ukuhamba, udlale indima yethutyana yokujikeleza, ukuze ulungise Ivalve yokunciphisa uxinzelelo okanye buyisela ivalve yokunciphisa uxinzelelo. 4. Izixhobo ezikhuselayo zomgibe: kukho iintlobo ezimbini zombhobho we-bypass kunye nombhobho we-bypass kumda womgibe, ukubuyiswa kwe-condensate kunye ne-condensate hayi intlawulo yokubuyisela, ukukhutshwa kunye nezinye iimfuno ezikhethekileyo zomgibe, zingafakwa ngokufanayo. Isicupho esinevalve yokudlula sisetyenziswa ikakhulu ukukhupha isixa esikhulu samanzi ajiyileyo xa umbhobho uqalisa ukusebenza. Xa UKHONZA UMTHETHO, AKUFANELEKILEYO UKUKHIPHA I-CONNDENSATE NGOMbhobho we-BYPASS, onokubangela ukuba umphunga ubaleke kwiNKQUBO YAMANZI YOKUBUYELA. Kwiimeko eziqhelekileyo, musa ukufaka umbhobho we-bypass. Kuphela xa ubushushu bokufudumala bufunwa ngokungqongqo, izixhobo ezishushu zokuvelisa ngokuqhubekayo kufuneka zixhotywe ngombhobho we-bypass. Amanqaku okuqwalaselwa ekusetyenzisweni kwevalve ye-fluorine yeplastiki ye-anti-corrosive Fluorine efakwe kwi-valve yeplastiki ye-anti-corrosion kwi-petroleum, ishishini lemichiza, iyeza, isinyithi, amandla ombane kunye namanye amashishini oqhagamshelwano lwe-asidi kunye ne-alkali kunye nezinye izixhobo ezomeleleyo zeendaba ezonakalisayo ibe sesona sicelo singcono, kodwa indlela yokukhetha okulungileyo, ukusetyenziswa kakuhle kwevalve yeplastiki ene-fluorine, ngokutsho kubasebenzisi bethu kwiminyaka yamava esicelo sentsimi, Ezi zilumkiso zilandelayo kufuneka zibekwe phambili ekusebenziseni ubushushu obuphakathi, uxinzelelo, umahluko woxinzelelo kunye nezinye iimeko xa ivalve ye-fluorine efakwe kwi-anti-corrosion valve ikhethiwe: 1, i-fluorine efakwe kwivalve yeplastiki yobushushu obuphakathi: Iindidi ezahlukeneyo zenkampani yethu yeevalvu zeplastiki ezinefluorine, ukusetyenziswa kweplastiki yefluorine yi-F46 (FEP), ukusetyenziswa kobushushu obuphakathi akunakudlula i-150 ℃ (ubushushu obuphakathi bunokuba yi-150 ℃ ixesha elifutshane, ixesha elide lokusetyenziswa kweqondo lokushisa kufuneka lilawulwe kwi-120 ℃), ngaphandle koko, i-valve components lining F46 kulula ukuthambisa, ukuguqulwa, okubangela ukuba ivalve ivalwe i-undead, ukuvuza okukhulu. Ukuba ubushushu bendawo esetyenziswayo bungaphantsi kwe-180℃ ixesha elifutshane, kwaye ubushushu bungaphantsi kwe-150℃ ixesha elide, kunokukhethwa olunye uhlobo lweplastiki yefluorine; I-PFA, kodwa ifakwe kwi-PFA fluorine iplastiki ibiza kakhulu kune-F46 ngexabiso. 2, musa ukuba noxinzelelo olubi. Ivalve yeplastiki enefluorine kufuneka ikuthintele ukusetyenziswa koxinzelelo olubi kumbhobho, ukuba kukho uxinzelelo olubi, kulula ukwenza ukuba umaleko weplastiki ofakwe kwifluorine kumngxuma wevalvu ufunxelwe ngaphandle (idrum ngaphandle), ukuxobula, okukhokelela ekuvulekeni kwevalvu kunye nokusilela kokuvala. . I-3, uxinzelelo, umahluko woxinzelelo kufuneka ulawulwe kuluhlu oluvumelekileyo. Ngokukodwa imifunduzo itywina ivalve yeplastiki elawulayo yefluorine, ivalve yeglowubhu. Ngenxa yokuba i-bellows yenziwe ngezinto ze-tetrafluoric, uxinzelelo kunye nokwahlukana koxinzelelo kukhulu, okunokuthi kube lula ukukhokelela ekugqabhukeni kweembhobho. I-Bellows itywina ivalve yokulawula iplastiki yefluorine, ukusetyenziswa koxinzelelo lwemeko, umahluko woxinzelelo mkhulu, unokutshintshwa ube yi-PTFE yokupakisha itywina. 4. Imeko ephakathi yevalve yeplastiki enomgca wefluorine kufuneka ingabi namasuntswana aqinileyo, iikristale, ukungcola, njl. njl., ukuze ingagugi isiseko sevalvu kunye nesihlalo sevalve esifakwe umaleko weplastiki yefluorine okanye i-PTFE bellows ekusebenzeni kokuvula nokuvala. I-medium ineengqungquthela ezinzima, iikristale, ukungcola, ukhetho, i-spool, isihlalo singasetyenziselwa i-Hastelloy. I-5, efakwe ivalve yokulawula iplastiki ye-fluorine kufuneka ihambelane nokuhamba okufunekayo (ixabiso le-Cv) ukhetho oluchanekileyo lwesayizi yevalve yedayamitha. Xa ukhetha, kufuneka ngokwemfuno yetrafikhi (i-Cv) kunye nezinye iiparamitha zobugcisa zibalwe ubungakanani bevalve kufuneka kukhethwe kunye nokuvulwa kwevalve, njengobungakanani bevalve enkulu kakhulu, ngokuqinisekileyo iya kwenza ivalve kwindawo yokuvula ixesha elide. ixesha ebalekayo, phantsi kwemeko kunokuba amancinane kunye noxinzelelo oluphakathi, ukuze kube lula ukwenza ivalve core kunye intonga ivelufa yimpembelelo eendaba kwaye wenze ivalve ingcangcazela, Intonga core ivelufa phakathi ixesha elide phantsi kwempembelelo, nokuba iyakwenza ukwaphuka kwesikhondo sevalve. Abasebenzisi ekukhethweni kwazo zonke iintlobo ze-fluorine ezifakwe kwi-valve zeplastiki, kufuneka zibe ngangokunokwenzeka ukuqonda, ukulawula ukusetyenziswa kweemeko zobugcisa, ukuze ukhethe, usebenzise kakuhle, uphucule ubomi benkonzo yevalve. Xa ingaphezu kobubanzi beemeko zobugcisa, kufuneka kucetywe kumenzi, kwaye amanyathelo okuphikisanayo ahambelanayo kufuneka athathwe ukuxazulula ingxaki ngokubonisana ngokubambisana.
