Inkqubo yokukhenkcisa, inkqubo yamanzi okupholisa, inkqubo yamanzi ekhenkcisa kunye nemibhobho yenkqubo yokunyibilikisa amanzi, iiflange, iivalvu, iimpompo zolwelo kunye nezikhongozeli, njl.njl., kuxinzelelo oluhlala lutshintsha kunye nobushushu ixesha elide, yi-refrigerant, i-refrigerant, amanzi, umoya kunye nezinye izinto ezibolayo, ulwakhiwo lwayo kunye nezinto ziya kwenzeka kumanqanaba ahlukeneyo okuncitshiswa okanye ukuguquguquka, ukuya kuthi ga kwinqanaba lokuba umda wobungakanani bengozi unokwenzeka.
1. Ukulungiswa kokuguqulwa kwendawo yombhobho
Ukuze kupheliswe ukuguquka kwendawo, kuyimfuneko ukufumanisa isizathu kwisakhiwo kunye nokusebenza. Njengombhobho wokukhupha umoya eludongeni lokugcina ubushushu ngokuqokelelwa komthwalo weqhwa obangelwa kukuguquka kakhulu, kufuneka kuqiniswe umsebenzi wokunyibilikisa. Ukuba umbhobho mde kakhulu, ukuguquka okubangelwa kukushiyana kwesithuba sebracket okanye ihanger, ibracket okanye ihanger kufuneka kwandiswe. Ukuba ukuguquka akukukhulu, akuchaphazeli ukusetyenziswa okuqhubekayo, kunokulinda uhlengahlengiso kuze kulungiswe, kodwa kufuneka kuqiniswe umsebenzi wokuhlola nokulungisa. Ukuba umbhobho ugobile kakhulu, inxalenye egobileyo yombhobho inokunqunyulwa emva kokuba ifriji ekwimbhobho ikhutshiwe kwaye ibekwe kwi-corrector ukuze ilungelelaniswe. Uxinzelelo kufuneka lulingane kwaye lucothe, ungabetheki nge-sledgehammer, kwaye umbhobho othe tye uqhagamshelwe kumbhobho wokukhupha umoya.
2. Ukulungiswa kwemingxunya yemibhobho kunye nemingxuma yayo
Ukuba izixhobo azikho nkulu, ngokuqhelekileyo sebenzisa indlela yokulungisa i-welding. Ukuba igesi ivuza, ukuvuza kwe-welding akufanele kube ngaphezu kwezihlandlo ezi-2, okanye kufuneka kutshintshwe ukuze kujongwane nombhobho. Xa uthungela indawo yokuvuza, akuvumelekanga ukusebenza kwindawo engqongileyo nge-refrigerant etyebileyo.
3. Ukulungiswa kweFlange
1) Jonga umthwalo wangaphambili weebholiti ekuqhagamshelweni kweflange, ukuba zikhululekile, qinisa iinati ngokulinganayo ngespanner ukuze wenze amandla afanayo, kodwa akufuneki ziqine kakhulu. Ukuba iibholiti zikhubazekile okanye zibole kakhulu, kufuneka kutshintshwe iibholiti ezintsha.
2) I-asbestos gasket ekuqhagamshelweni kweflange ibolile okanye itshile, nto leyo ebangela ukuba ingabi namandla okuvala, kwaye kufuneka itshintshwe nge-gasket entsha. Ngaphambi kokutshintsha i-gasket entsha, i-gasket yokuqala kufuneka ikhuhlwe kwaye icocwe ngeparafini ukujonga ukuba umgca wokuvala iflange ubolile okanye wonakele. Ukuba akukho ngxaki ingatshintshwa nge-gasket entsha, ukuqina kwe-flange bolts okulinganayo kunokubakho. Ukuba umphezulu wokuvala weflange uchaphazeleka kakhulu kukubola okanye umonakalo womgca wokuvala, ungayitshintsha i-flange entsha okanye uyilungise kwaye uyifake kwi-gasket entsha ukuthintela ukusetyenziswa kokuvuza.
3) Umthungo wokuwelda awuqinanga, kufuneka ulungiswe nge-welded.
4) Ukuba ukuwelda kubangela ukuba iflange igobe kwaye ayihlangabezani neemfuno zokuhlanganiswa, kufuneka ijikwe kwaye icutshungulwe okanye itshintshwe.
5) Kwinkqubo yokufakela, ukuba umgca ophakathi weeflanges ezimbini awufani, umphezulu womphezulu woqhagamshelwano awufani, umbhobho kufuneka unqunyulwe uze uphinde udityaniswe.
4. Ukulungiswa kweevalvu
1) Ukutshintshwa kwepakethi. Eyona ndima iphambili yokupakisha kukuthintela ukuvuza okuncinci kunye nokuphuma kwe-axial kwi-valve stem. Kwimeko yokuvuza okuncinci, i-packing gland ingaqina, njengoko ukuvuza akunakukhutshwa, kufuneka ithathe indawo yokupakisha. Ukutshintshwa kwe-valve stem kufuneka kukrwelwe kude kube sekupheleni, kunye ne-packing pin ukuya kwi-packing endala, uze ulungele ukukrwela i-packing entsha ngokulandelelana, uze uqinise i-gland.
2) Lungisa i-spool. Kwiiprojekthi zokupholisa umoya kunye nezokukhenkceza, apho ububanzi obukhulu bevalvu buxhomekeke kumaleko we-alloy e-pasteurized okanye i-fluorine plastic seal. Umva we-spool ukwanomaleko we-alloy e-pasteurized, ukuze xa i-valve stem ikhutshiwe iye kwindawo esezantsi, ikwazi ukuvala izinto ngaphandle kokuvuza ngaphandle ecaleni kwe-valve stem.
Xa ivalvu iqhekekile, qala ngokulungelelanisa isiqu sevalvu ukuze siphume, uze emva koko utshintshe i-spool ye-alloy ephekiweyo, kwaye kwangaxeshanye, isihlalo sevalvu naso masigaywe, ukuze i-spool kunye nesihlalo sevalvu ziqine.
Kwi-spool yentsimbi encinci okanye ye-brass valve, i-seal yale valve ixhomekeke kumgca woqhagamshelwano lwesinyithi ukuze ifumane, okubizwa ngokuba yi-line seal. Ngenxa yokuba yi-line seal, ngoko ke isihlalo se-valve kunye ne-spool kufuneka zigaywe ngononophelo ukuze kufunyanwe isiphumo sokuvala esanelisayo.
Ukulungiswa kwevalvu kugqityiwe, kufuneka kuhambelane neemfuno ezifanelekileyo zovavanyo lokungena komoya.
Inkqubo yokukhenkcisa ekulungisweni kwevalvu yokhuseleko nayo ifana kakhulu nale ingasentla, kodwa ngenxa ye-alloy ethambileyo efakwe i-pasteurized, edla ngokubangelwa kukucinezeleka kakhulu kunye nokusebenza kwevalvu yokhuseleko emva kwexesha elithile, kunzima ukubuyela kwindawo yokuqala, ngoko ke xa uxinzelelo luhla luye kuxinzelelo lokuvala, ukuvala akuqini. Ukuze koyiswe esi siphene, ezinye iimveliso zitshintshwe nge-alloy ye-nickel-chromium-titanium (hard), okanye nge-polytetrafluoroethylene endaweni yoko.
