1. I-COMMPACT BALL VALVE X9002 kufuneka igcinwe kwigumbi elomileyo nelingena umoya, kwaye zombini iziphelo zepaseji mazivalwe.
2. Iivalvu ezigcinwe ixesha elide kufuneka zihlolwe rhoqo ukuze zisuse ukungcola kwaye zisebenzise ioli echasene ne-rust kwindawo yokucubungula.
3. Emva kofakelo, ukuhlolwa rhoqo kufuneka kwenziwe, izinto zokuhlola eziphambili:
(1) Nxiba umgangatho wokutywina.
(2) Ukunxitywa kwemisonto ye-trapezoidal ye-valve stem kunye ne-valve stem nut.
(3) Ingaba ukupakisha kuphelelwe yisikhathi kwaye akuvumelekile, ukuba konakaliswe, kufuneka kutshintshwe ngexesha.
(4) Emva kokuba ivalve igqitywe kwaye idityanisiwe, uvavanyo lomsebenzi wokutywina kufuneka lwenziwe.
Umsebenzi wokulungisa ngexesha lokutofa kwegrisi yevalvu
Ukugcinwa kwe-valve ngaphambi nangemva kwenkqubo ye-welding kudlala indima ebalulekileyo ekuveliseni nasekusebenzeni kwe-valve.Ukugcinwa okuchanekileyo, okucwangcisiweyo kunye nokusebenzayo kuya kukhusela i-valve, yenza i-valve isebenze ngokuqhelekileyo kwaye yandise ukusetyenziswa kwe-valve.ubomi.Ukugcinwa kwevalve kunokubonakala kulula, kodwa akunjalo.Kukho iinkalo ezininzi zomsebenzi ezingahoywayo.
1. Xa ivalve ifaka igrisi, ingxaki yomthamo wegrisi isoloko ingahoywa.Emva kokuba umpu wegrisi ufakwe i-refueled, umqhubi ukhetha ivalve kunye nemowudi yokudityaniswa kwenaliti yegrisi, aze enze umsebenzi wokutofa igrisi.Kukho iimeko ezimbini: kwelinye icala, inani lenaliti yegrisi lincinci, kwaye inaliti yegrisi ayanelanga, kwaye umphezulu wokutywina unxiba ngokukhawuleza ngenxa yokunqongophala kwe-lubricant.Kwelinye icala, inaliti yamafutha amaninzi ibangela inkcitho.Isizathu sikukuba akukho kubalwa komthamo wokutywina wevalve eyahlukileyo ngokodidi lwevalvu.Umthamo wokutywina unokubalwa ngokusekelwe kubungakanani bevalve kunye nohlobo, kwaye ke isixa esifanelekileyo segrisi sinokutofwa.
2. Xa i-valve ifakwe igrisi, ingxaki yoxinzelelo ihlala ingahoywa.Ngexesha lokutofa kwamafutha, uxinzelelo lwenaliti yamafutha lutshintsha rhoqo kwiincopho kunye neentlambo.Ukuba uxinzelelo lusezantsi kakhulu, itywina liyavuza okanye aliphumeleli, uxinzelelo luphezulu kakhulu, indawo yokutofa igrisi ivaliwe, igrisi esesitywinweni iqinisiwe, okanye iringi yokutywina itshixiwe ngebhola yevalve kunye nepleyiti yevalvu.Ngokuqhelekileyo, xa uxinzelelo lwenaliti yegrisi lusezantsi kakhulu, igrisi etofwayo ikholisa ukuqukuqela ukuya kumazantsi omgodi wevalvu, oqhele ukwenzeka kwiivalvu zesango ezincinci.Ukuba uxinzelelo lwenaliti yegrisi luphezulu kakhulu, kwelinye icala, jonga umbhobho wenaliti yegrisi, ukuba umngxuma wegrisi uvalekile, yibuyisele endaweni yawo;kwelinye icala, ukuba igrisi iqinisiwe, sebenzisa ulwelo lokucoca ukuthambisa ngokuphindaphindiweyo igrisi yokutywina engaphumelelanga kwaye utofe igrisi entsha ukuyibuyisela..Ukongeza, uhlobo lwetywina kunye nezinto zokutywina nazo zichaphazela uxinzelelo lwenaliti yegrisi.Iindlela zokutywina ezahlukeneyo zineexinzelelo ezahlukeneyo zokutofa igrisi.Ngokubanzi, uxinzelelo lwenaliti yegrisi yamatywina aqinileyo kufuneka ibe lelona tywina libhetyebhetye.
3. Xa i-valve ifakwe igrisi, nikela ingqalelo kwingxaki yevalve kwindawo yokutshintsha.Ivalve yebhola ngokuqhelekileyo ikwindawo evulekileyo ngexesha lolondolozo.Kwiimeko ezikhethekileyo, kukhethwe ukuba kuvalwe ukugcinwa.Ezinye iivalvu azikwazi ukuphathwa njengeendawo ezivulekileyo.Ivalve yesango kufuneka ivalwe ngexesha lolondolozo ukuqinisekisa ukuba igrisi izalise igroove yokutywina ecaleni kweringi yokutywina.Ukuba ivuliwe, igrisi yokutywina iya kuwela ngokuthe ngqo kumjelo wokuhamba okanye i-valve cavity, ibangele inkunkuma.
4. Xa i-valve ifakwe igrisi, ingxaki yefuthe le-grease injection idla ngokungahoywa.Ngexesha lomsebenzi wokutofa igrisi, uxinzelelo, umthamo wenaliti yegrisi, kunye nendawo yokutshintsha zonke ziqhelekile.Nangona kunjalo, ukwenzela ukuba kuqinisekiswe umphumo we-valve grease injection, ngamanye amaxesha kuyimfuneko ukuvula okanye ukuvala i-valve ukujonga umphumo we-lubrication ukuqinisekisa ukuba umphezulu webhola ye-valve okanye isango lixutywe ngokulinganayo.
5. Xa utofa igrisi, nikela ingqalelo kwingxaki ye-valve body drainage kunye ne-plug pressure relief.Emva kovavanyo loxinzelelo lwevalvu, irhasi kunye nokufuma kumngxunya wevalve yecango evaliweyo kuya kwanda kuxinzelelo ngenxa yokwanda kobushushu obuphakathi.Xa igrisi itofwa, ugutyulo kunye noxinzelelo kufuneka lukhutshwe ukuze kube lula ukuqhubeka kakuhle kwenaliti yegrisi.Emva kokuba igrisi ifakwe, umoya kunye nomswakama kwindawo evaliweyo zitshintshwa ngokupheleleyo.Ukunciphisa uxinzelelo lwevalvu ngexesha, nto leyo eqinisekisa ukhuseleko lwevalve.Emva kwenaliti yegrisi, qiniseka ukuba uqinise umsele kunye neplagi yokukhulula uxinzelelo ukukhusela iingozi.
6. Xa ufaka igrisi, nikela ingqalelo kwingxaki yokukhutshwa kwegrisi efanayo.Ngexesha lokutofa okuqhelekileyo kwegrisi, indawo yokuphuma igrisi ekufutshane nezibuko lokutofa igrisi iya kuphuma kuqala, iye kwindawo esezantsi, emva koko iye kwindawo ephezulu emva kweyokugqibela, emva koko ikhuphe igrisi ngokulandelelanayo.Ukuba ayilandeli imigaqo okanye ayivelisi amanqatha, ingqina ukuba kukho ukuvaleka, kwaye uyicacise ngexesha.
7. Xa utofa igrisi, jonga kwakhona ingxaki yokugungxulwa kwedayamitha yevalvu kunye nesitulo seringi yokutywina.Ngokomzekelo, kwiivalve zebhola, ukuba kukho ukuphazamiseka kwendawo evulekileyo, umda wokuvula indawo ovulekileyo unokulungiswa ngaphakathi ukuze uqinisekise ukuba ububanzi buchanekile kwaye butshixiwe.Ukulungelelanisa isikhundla somda, akufanele ulandele indawo yokuvula okanye yokuvala kuphela, kodwa kufuneka uqwalasele indawo yonke.Ukuba indawo yokuvula i-flush kwaye indawo yokuvala ayikho, i-valve ayiyi kuvala ngokuqinileyo.Ngendlela efanayo, ukuba ulungelelwaniso lukhona, ukulungiswa okuhambelanayo kwendawo evulekileyo kufuneka kuqwalaselwe.Qinisekisa uhambo oluchanekileyo lwe-engile yevalvu.
8. Emva kokutofwa kwegrisi, indawo yokutofa igrisi kufuneka ivalwe.Kuphephe ukungena kokungcola okanye i-oxidation ye-lipids kwindawo yokutofa igrisi.I-anti-rust grease kufuneka ifakwe kwisigqubuthelo ukuphepha umhlwa.Ukuze isetyenziswe kumsebenzi olandelayo.
I-9.Nine, xa ujova igrisi, kuyimfuneko kwakhona ukuqwalasela unyango oluthile lweengxaki ezithile ekuthuthweni okulandelelanayo kweemveliso zeoli kwixesha elizayo.Ngenxa yeempawu ezahlukeneyo zedizili kunye nepetroli, kufuneka kuthathelwe ingqalelo ubungakanani be-scour kunye nokubola kwepetroli.Kwixesha elizayo lomsebenzi wevalve, xa udibana nokusebenza kwecandelo lepetroli, gcwalisa igrisi ngexesha lokuthintela ukunxiba.
10. Xa utofa igrisi, musa ukuyihoya inaliti yegrisi kwisiqu sevalvu.Kukho umkhono we-sliding okanye ukupakisha kwi-valve shaft, nayo kufuneka igcinwe i-lubricated ukunciphisa ukuxhatshazwa kwefriction ngexesha lokusebenza.Ukuba i-lubrication ayinakuqinisekiswa, i-torque iya kwanda ngexesha lokusebenza kombane kwaye iindawo zokugqoka ziya kuba nzima ngexesha lokusebenza ngesandla.
11. Ezinye iivalve zebhola ziphawulwe ngeentolo kumzimba wevalvu.Ukuba akukho kubhalwa kwe-FIOW yesiNgesi, isalathiso sesenzo sesihlalo sokutywina, esingasetyenziswanga njengesalathiso sokuhamba komzila we-medium, kunye nolwalathiso lwe-valve self-discharge luchasene.Ngokuqhelekileyo, i-valve yebhola etywiniweyo enezihlalo ezibini ine-bidirectional flow direction.
12. Xa ugcina i-valve, qaphela ukungena kwamanzi kwintloko yombane kunye nendlela yokuhambisa.Ingakumbi imvula engena ngexesha leemvula.Enye yeyokurusa isixhobo sothumelo okanye umkhono weshafti wothumelo, ukanti omnye kukukhenkceza ebusika.Yenza ukuba i-torque ibe nkulu kakhulu xa ivalve yombane isetyenziswa, kwaye umonakalo kwiindawo zothumelo ziya kubangela ukuba imotor yothulwe okanye *ukhuseleko lwetorque luya kukhubeka kwaye ukusebenza kombane akunakwenzeka.Amalungu othumelo wonakaliswe, kwaye umsebenzi wezandla awukwazi ukwenziwa.Emva kokuba *ukhuseleko lwetorque luvuliwe, ukusebenza kwezandla nako akunakutshintshwa.Ukusebenza okunyanzeliswayo kuya konakalisa iinxalenye ze-alloy zangaphakathi.
