Jonga umfanekiso oMkhulu
Ngaba ukhe uzibuze ukuba zenziwa njani iivalvu zeshishini?Inkqubo yombhobho ayigqibekanga ngaphandle kweevalve.Kuba ukhuseleko kunye nobomi benkonzo zezona zinto zixhalabisayo kwinkqubo yombhobho, kubalulekile ukuba abavelisi beevalvu banikezele ngeevalvu ezikumgangatho ophezulu.
Yintoni imfihlelo emva kweevalvu eziphezulu zokusebenza?Yintoni ebenza babe ngcono ekusebenzeni?Ngaba zizixhobo?Ngaba oomatshini bokulinganisa babalulekile kangako?Inyaniso kukuba, yonke le miba.Ngaphambi kokuba uqonde iinkcukacha ezimfutshane zevalvu yeshishini, umntu kufuneka azi ngakumbi malunga nokuba zenziwa njani iivalvu.
Eli nqaku liza kuxubusha ukuveliswa kweevalvu zoshishino ukusuka ekuqaleni ukuya ekupheleni.Oku kuya kubonelela abafundi ngolwazi malunga nokuveliswa kwevalvu kunye nokulungiswa.
1. Umyalelo kunye noYilo
Okokuqala, umthengi kufuneka abeke iodolo, nokuba yivalve elungiselelweyo okanye into efunyenwe kuludwe lweziyilo zevalvu esele zikhona.Kwimeko yokwenziwa ngokwezifiso, inkampani ibonisa uyilo kumthengi.Emva kokuvunywa kokugqibela, ummeli wentengiso ubeka umyalelo.Umthengi ukwabonelela ngedipozithi echazwe kwangaphambili kwinkampani.
2. Uluhlu lwempahla
Nje ukuba ukufakwa kwee-odolo kunye noyilo kuqalisile, isebe lemveliso liya kukhangela imathiriyeli ekrwada yesiqu, i-spool, umzimba kunye nebhonethi.Ukuba akukho mathiriyeli yaneleyo, isebe lemveliso liya kuzithenga ezi mathiriyeli kubaboneleli.
3. Ukuzalisa uluhlu lokutshekisha
Nje ukuba izixhobo zonke zikhona, iqela lokuvelisa lihamba ngaphaya koluhlu kwakhona ukuqinisekisa ukuba yonke into igqityiwe.Kukwangelo xesha apho ukwamkelwa koyilo lokugqibela loyilo lwenzeka.Ukongeza, iqela lokuqinisekisa umgangatho lijonga izinto ngokucokisekileyo.Oku kukuqinisekisa ukuba imathiriyeli ekrwada yeyomgangatho ogqwesileyo.
4. Inkqubo yeMveliso
Oku kuquka uninzi lwemisebenzi ephathelele kwinkqubo yokwenziwa kweevalvu zemizi-mveliso.Icandelo ngalinye eliphambili lenziwa ngokwalo.Amaxesha amaninzi, kukho uluhlu lokukhangela olubandakanya onke amagama eendawo ezisecaleni kunye nokuba yeyiphi imathiriyeli enokusetyenziswa kwisixhobo ngasinye.
Kungesi sihlandlo apho inkokeli yeqela ibonelela ngomda wexesha lokwenziwa kokwenyani, ukusuka ekuqaleni komsebenzi ukuya kumhla wokugqiba.Kwakhona, inkokeli ihlala isenza isicwangciso esineenkcukacha zokusebenza.
Kuxoxiwe ngezantsi iindlela ezimbini eziqhelekileyo zendlela iivalvu zenziwa ngayo.
#1: Indlela yokuphosa
Indlela yokuphosa ingashwankathelwa ngokujonga lo mfanekiso ungezantsi.Qaphela ukuba oku akusiyo inkqubo epheleleyo.
● Umzimba
Isixhobo sokuqala esakhiwe ngaphambili sicociwe.Inkqubo yokuguqula yenziwa emva kokucoca.Ukuguqula yindlela yokususa izinto ezingaphezulu ngokusika usebenzisa i-lathe okanye umatshini wokuguqula.Kubandakanya ukudibanisa umzimba owenziwe ngaphambili kwintaba kunye nomatshini wokujika.Lo matshini ujikeleza ngesantya esiphezulu.Ngelixa ijikeleza, i-cutter-point-point cutter inqumla umzimba ngendlela oyifunayo kunye neyodwa.Ngaphandle koko, ukujika kunokwenza i-grooves, imingxuma, phakathi kwabanye.
Isinyathelo esilandelayo kukongeza isinyithi se-plating, ngokuqhelekileyo, ubhedu kumacandelo ahlukeneyo omzimba.I-Copper plating iqinisekisa ukutywinwa okupheleleyo nokufanelekileyo komzimba.
Inyathelo elilandelayo kukumenyezwa komzimba.Emva koko, amagcisa enza imisonto evumela ukuncamathelwa kweendawo ezithile zevalve kwezinye izinto okanye imibhobho.Iivalvu zifuna imingxunya ukuze ukugqobhoza kwenzeke emva koku.Qaphela ukuba ivalve nganye inobukhulu obahlukeneyo bomngxuma, kuxhomekeke kwimfuno.Kulapho imimiselo nemigangatho ingena khona.
Amagcisa apeyinta iivalvu ngeTeflon okanye ezinye iindidi zeelastomer.Emva kokupeyinta, kubhaka.Iibhondi zeTeflon kunye nomzimba ngokubhaka.
● Isihlalo
Isihlalo siqhuba inkqubo efanayo nomzimba.Ekubeni isihlalo singaphakathi emzimbeni kwaye njengenxalenye yomsebenzi wayo wevalvu- ukutywinwa ngcono- ifuna ukulingana ngokugqibeleleyo kuncamathiselo yayo.Ngelixa umzimba uneTeflon kuphela, isihlalo njengesisongelo esongezelelweyo serabha ukuqinisekisa ukomelela okuqinileyo.
● Isiqu
Njengakwimeko yesiqu, akufuneki ukuba ibe nemveliso eninzi.Kunoko, ukusika ezi kwimilinganiselo efanelekileyo kubalulekile.
#2: Indlela yokwenziwa
Indlela yokwenziwa ingashwankathelwa kule nkqubo ingezantsi.Ngokufanayo, le nkqubo ingezantsi igxininisa kuphela ukuba yintoni na indlela eyenziwe ngayo.
● Ukusika Nokwakha
Emva kokukhethwa kwezinto eziphathekayo, inkqubo elandelayo kukunqumla ubude kunye nobubanzi obufunekayo.Inyathelo elilandelayo kukulungisa indawo nganye ngokuyifudumeza ngokuyinxenye ukuya kwinqanaba elithile.
● Ukucheba
Inyathelo elilandelayo kukucheba.Apha kulapho izinto ezigqithisileyo okanye i-burr isuswa khona.Emva koko, umzimba uyadanyaza ukuze uwubumbe ngendlela efanelekileyo.
● Ukudubula kwesanti
Ukuqhunyiswa kwesanti linyathelo elilandelayo.Oku kwenza ivalve igudiswe kwaye icoceke.Ubungakanani besanti esetyenzisiweyo buxhomekeke kwiimfuno zabathengi okanye imigangatho.Iivalvu zihlelwa ekuqaleni ukuze kususwe ezo zineziphene.
● Oomatshini
Ukutshiza kwandisa ngakumbi ubungakanani kunye neemilo zemisonto, imingxuma kunye nezinto ezithandwayo, kwakhona, kuxhomekeke kuyilo kunye neemfuno zomthengi.
● Unyango Lwendalo
Ivalve ingena kunyango lomphezulu isebenzisa iiasidi ezithile kunye nezinto ezithandwayo.
5. INdibano
INdibano sisigaba apho amagcisa ancamathisela onke amacandelo evalvu enye kwenye.Amaxesha amaninzi, indibano yenziwa ngesandla.Kulo nqanaba apho amagcisa anikezela iinombolo zokuvelisa iivalve kunye nokutyunjwa ngokwemigaqo elandelwayo njenge-DIN okanye i-API kunye nezinto ezithandwayo.
6. Uvavanyo loxinzelelo
Kwinqanaba lovavanyo loxinzelelo, iivalvu kufuneka zenze uvavanyo lokwenene loxinzelelo lokuvuza.Kwezinye iimeko, umoya kunye noxinzelelo lwe-bar ye-6-8 ugcwalisa i-valve evaliweyo ngenani elithile leeyure.Inokuqala ukusuka kwiiyure ezi-2 ukuya ngosuku, kuxhomekeke kubungakanani bevalvu.
Ukuba kukho ukuvuza emva kwexesha, ukulungiswa kwevalvu kwenzeka.Ngaphandle koko, i-valve iya kudlulela kwisigaba esilandelayo.
Kwezinye iimeko, ukuvuza kufunyenwe ngoxinzelelo lwamanzi.Ukuba i-valve ayivuzi njengoko umthamo wamanzi unyuka, uphumelela uvavanyo.Oku kuthetha ukuba i-valve inokumelana noxinzelelo olukhulayo.Ukuba kukho ukuvuza okuthile, ivalve ibuyela kwindawo yokugcina impahla.Amagcisa aya kukhangela ukuvuza kwamanzi phambi kokuba enze enye iseti yovavanyo loxinzelelo kule bhetshi yeevalvu.
7. Ukuhlolwa kunye noLawulo loMgangatho
Ngeli xesha, abasebenzi be-QA baya kuhlola iivalve ngokucokisekileyo malunga nokuvuza kunye nezinye iimpazamo zokuvelisa.
Jonga le vidiyo ukuze ubone indlela ivalve yebhola eyenziwe ngayo.
Isishwankathelo
Inkqubo yokwenziwa kwevalvu yeshishini ngumzamo onzima.Akunjalo nje indalo elula yevalve.Izinto ezininzi zinegalelo ekusebenzeni kwayo: ukuthengwa kwempahla ekrwada, umatshini, unyango lobushushu, i-welding, indibano.Iivalvu kufuneka zivavanywe ngokungqongqo ukuqinisekisa ukusebenza ngokufanelekileyo phambi kokuba abavelisi bazinikezele kumthengi.
Omnye unokubuza, yintoni eyenza ivalve yomgangatho ophezulu?Enye yezinto ezigqibayo zokwazi iivalve ezikumgangatho ophezulu kuvavanyo lwexesha.Iivalvu zenkonzo ende zithetha ukuba zisemgangathweni olungileyo.
Ngakolunye uhlangothi, xa i-valve ibonisa ukuvuza kwangaphakathi, amathuba okuba, iindlela zokuvelisa ezisetyenzisiweyo azikho kwimigangatho efunekayo.Ngokuqhelekileyo, iivalve ezingcono zingahlala ukuya kwiminyaka emi-5 ngelixa ezomgangatho ophantsi zinokuhlala iminyaka emi-3 kuphela.
