Amanyathelo okukhusela xa ufaka iivalve Ukusebenza rhoqo kwe-fluorine lined anticorrosive valves

 
Xa i-valve ifakwe, umsebenzisi akufanele aqonde kuphela indlela yokufakela kwayo, kuba i-valve ifakwe xa ukhuseleko lubaluleke kakhulu. Ukuba awuyikunyamekela ngexesha lofakelo, kulula ukwenza umonakalo okanye ukuvuza kwevalve, okuya kubangela ingxaki enkulu. Ngoko indlela yokukhusela xa ufaka i-valve? I-Xiaobian elandelayo iya kwazisa ngokuthe ngqo amanyathelo okukhusela okufakwa kwevalve.
Khangela ukhuseleko lwevalvu
UKUBA KUTHINTELE ukuvuza kwe-valve yokukhangela okanye ukubuya kweendaba emva kokungaphumeleli, okubangelwa ukuhla komgangatho wemveliso, izingozi kunye nezinye iziphumo ezibi, enye okanye ezimbini i-valve yokuqhawula i-valve ibekwe ngaphambi nangemva kwe-valve yokukhangela. Ukuba iivalve ezimbini zokuvala zibonelelwe, ivalve yokukhangela inokususwa ngokulula kwinkonzo.
Amaziko okukhusela ivalvu yokhuseleko
Indlela yokufakela ngaphambi nangemva kokuba ngokubanzi musa ukuseta i-valve yokwahlula, kuphela kwiimeko zomntu ngamnye, ingasetyenziswa. 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 umthwebeba kunye nezinye eendaba kwiqondo lobushushu begumbi kwimeko eqinileyo, okanye ukunciphisa uxinzelelo gasification kwaye ukuze ulwelo ukukhanya eliphakathi lobushushu ngaphantsi 0 degrees Celsius, ivelufa yokhuseleko kufuneka ubushushu umphunga. Ivalve yokhuseleko kumajelo eendaba ezonakalisayo, ngokuxhomekeke ekuxhathiseni umhlwa kwevalve, cinga ukongeza ifilimu ekwaziyo ukumelana nokudubula kwindawo yevalve. Ivalve yokhuseleko lwegesi ngokuqhelekileyo ibonelelwa ngevalve yokudlula ngokobungakanani bayo, njenge-vent manual.
Izixhobo ezikhuselayo zevalve yokunciphisa uxinzelelo
Amaziko ofakelo lwevalvu yokunciphisa uxinzelelo ngokubanzi aneendlela ezintathu. 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 wokucoca ufakwe phambi kwe-valve 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.
Izixhobo zokukhusela umgibe
Kukho iintlobo ezimbini zeemigibe ezinombhobho we-bypass kwaye akukho mbhobho odlulayo kwicala lomgibe, 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.
Ukusebenza rhoqo kwevalve ye-anticorrosive ene-fluorine
I-1, i-fluorine efakwe kwivalve yeplastiki ye-valve ephakathi kobushushu: Iintlobo ezahlukeneyo zenkampani yethu ye-fluorine ifakwe kwiivalvu zeplastiki, ukusetyenziswa kweplastiki ye-fluorine yi-F46 (FEP), ukusetyenziswa kobushushu obuphakathi akunakudlula i-150 ℃ (ubushushu obuphakathi bunokuba yi-150 ℃ ixesha elifutshane ixesha elide, ubushushu bokusetyenziswa kwexesha elide kufuneka ilawulwe kwi-120 ℃), ngaphandle koko, i-valve components lining F46 ilula ukuthambisa, i-deformation, ebangela 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, ukuhluka koxinzelelo kufuneka kulawulwe 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 ihambisane 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.
