Zonke iintlobo zevalvu esetyenziswa ngokuxhaphakileyo iindlela zogcino zesivalo esincinci seyunivesithi sabuza: isaziso sokuthenga ivalve yosapho esetyenziswa ngokuqhelekileyo

Zonke iintlobo zevalvu esetyenziswa ngokuqhelekileyo iindlela zogcino ezisixhenxe ivalufa iyunivesiti wabuza: usapho ezisetyenziswa rhoqo isaziso sokuthenga isivalo Ivalve kwimveliso yoshishino, ubomi kuzo zonke iinkalo zobomi zisetyenziswa kakhulu, ngumbhobho wamanzi asekhaya, umbhobho wolwelo lwamashishini isixhobo esiyimfuneko. Mncinane njengombhobho wamanzi wekhaya, omkhulu njengeDama leeGorges eziThathu, iplanti yamandla enyukliya yaseQinshan, kunye nesiphekepheke sothotho lweShenzhou kunye neSikhululo saMajukujuku saMazwe ngaMazwe, izivalo zidlala indima ebalulekileyo embindini. Ngoko ukusetyenziswa kwevalve kufuneka kuhlawulelwe ingqalelo ekugcinweni, ivalve ekusetyenzisweni kwenkqubo, kufuneka ihlale icocekile, intambo yokuhambisa kufuneka ithanjiswe rhoqo, ifunyenwe iphoso, kufuneka iyeke ngokukhawuleza ukusebenzisa, fumana unobangela wempazamo. I-Valve kwimveliso yemizi-mveliso, ubomi kuzo zonke iinkalo zobomi busetyenziswa kakhulu, ngumbhobho wamanzi wasekhaya, umbhobho wolwelo lwamashishini isixhobo esiyimfuneko. Mncinane njengombhobho wamanzi wekhaya, omkhulu njengeDama leeGorges eziThathu, iplanti yamandla enyukliya yaseQinshan, kunye nesiphekepheke sothotho lweShenzhou kunye neSikhululo saMajukujuku saMazwe ngaMazwe, izivalo zidlala indima ebalulekileyo embindini. Ngoko i-valve kufuneka inikele ingqalelo ekugcinweni, ukuthetha ngokulondolozwa, ngaba uyazi ukuba ungayigcina njani ivalve? Iindlela ezisixhenxe zokugcinwa kwevalve zezi zilandelayo: 1, ivalve kwinkqubo yokusetyenziswa, kufuneka ihlale icocekile, intambo yokuhambisa kufuneka ithanjiswe rhoqo, ifunyenwe impazamo, kufuneka iyeke kwangoko ukusebenzisa, fumana unobangela wempazamo. I-2, ukupakisha iibholithi zedlala kufuneka ziqiniswe ngokulinganayo, akufanele zicinezelwe kwimo egoso, ukuze ugweme umonakalo wokuthintela ukunyakaza kwesiqu okanye kubangele ukuvuza. 3. Xa ufaka, i-valve inokufakwa ngokuthe ngqo kumbhobho ngokwendlela yokudibanisa. NGOKUBANZI, IYA KUFAKWA kuyo nayiphi na indawo yombhobho, kodwa kufuneka kube lula ukusebenza ukugcinwa, ingqalelo ukuhamba kwe-globe medium valve kufuneka ibe phantsi kwe-longitudinal valve disc ukuya phezulu, i-valve yokukhangela i-valve ingaba kuphela. ifakwe ngokuthe tye. I-4, ivalve yebhabhathane, ivalve yebhola, ivalve yeglowubhu, ivalve yesango, ivuleke ngokupheleleyo okanye ivalwe ngokupheleleyo, ungavumeli ukulungelelanisa ukuhamba, ukuze ugweme ukukhukuliseka komhlaba, ukukhawuleza ukunxiba. Ivalve yesango kunye nevalve yeglowubhu yomsonto ephezulu inesixhobo sokutywina esiguqulweyo, kwaye ivili lesandla lijikelwe kwindawo ephezulu ukuze liqinise, elinokuthi lithintele imidiya ekuvuzeni ekupakisheni. I-5, i-valve ye-butterfly, i-valve yebhola, i-valve yeglobhu, i-valve yesango ivule kwaye ivale ukusetyenziswa kwe-handwheel, ungasebenzisi i-levers okanye ezinye izixhobo, ukuze ungonakalisi iindawo zevalve. Jika ivili lesandla ngasekunene ukuvala, ngokuphendululekileyo ukuze uvule. 6. Ngaphambi kokufakela, kuyimfuneko ukujonga ngokucophelela ukunyanzeliswa kophawu lwe-valve, nokuba ububanzi buhlangabezana neemfuno zokusetyenziswa, ukuphelisa iziphene ezibangelwa yinkqubo yokuthutha, kunye nokuphelisa ukungcola kwe-valve. Iivalve ezi-7, ukugcinwa kwexesha elide, kufuneka zihlolwe rhoqo, kuba ukuvuza kwendawo yokucubungula kufuneka kucoceke, ukungcola, ukugcinwa kunye nokuphela xa ivalve yebhola kufuneka ivalwe kwindawo evulekileyo, ivalve yebhabhathane, ivalve yesango, ivalve yeglowubhu, itshekhi ivalve, iziphelo zetshaneli kufuneka zivaliwe kwaye zivaliwe, zigcinwe ngokucocekileyo kwindawo eyomileyo yangaphakathi kunye nomoya, musa ukufumba okanye kumoya ovulekileyo. Ivalve yeyunivesithi encinci yabuza: isaziso sokuthengwa kwevalve yosapho xa ukhetha ukujonga ivalve ngembonakalo, umphezulu kufuneka ube ngaphandle kwetrakoma; Umphezulu we-Electroplating kufuneka ube yi-luster efanayo, kufuneka ubeke ingqalelo ukuba kukho ukuxobulwa, ukuqhekeka, ukuculwa, ukutyhila ezantsi, ukuxobula, amabala amnyama kunye neziphene ezicacileyo zomgodi; Umphezulu wokutshiza kufuneka ulunge, ugudiswe kwaye ufane, ngaphandle kweziphene ezifana nokuxhoma okuhamba kunye nokuvela ngaphantsi. Iivalve zoluntu ziqhele ukusetyenziswa ziintsapho eziqhelekileyo ngendlela yeevalvu zesango, iivalve zebhola, iivalve ezinxantathu, njl., ngokuqhelekileyo zenziwe ngentsimbi okanye ubhedu. Ngenxa yeempawu ezilungileyo zomatshini we-alloy yobhedu, ineenzuzo zokungabi lula ukugqwala kunye nokuxhathisa okuqinileyo, ngoko ivalve yobhedu iye yatshintsha ngokuthe ngcembe ivalve yentsimbi Xa kuthengwa ivalve yokuhlola ebonakalayo, umphezulu kufuneka ukhululeke kwi-trachoma; Umphezulu we-Electroplating kufuneka ube yi-luster efanayo, kufuneka ubeke ingqalelo ukuba kukho ukuxobulwa, ukuqhekeka, ukuculwa, ukutyhila ezantsi, ukuxobula, amabala amnyama kunye neziphene ezicacileyo zomgodi; Umphezulu wokutshiza kufuneka ulunge, ugudiswe kwaye ufane, ngaphandle kweziphene ezifana nokuxhoma okuhamba kunye nokuvela ngaphantsi. Iivalve zoluntu ziqhele ukusetyenziswa ziintsapho eziqhelekileyo ngendlela yeevalvu zesango, iivalve zebhola, iivalve ezinxantathu, njl., ngokuqhelekileyo zenziwe ngentsimbi okanye ubhedu. Ngenxa yezinto ezilungileyo zomatshini we-alloy yobhedu, ineenzuzo zokungabi lula ukugqwala kunye nokumelana nokuqina kwe-corrosion, ngoko ivalve yobhedu ithathe indawo yevalve yentsimbi ngokuthe ngcembe. Umphezulu wevalve engunxantathu ngokusisiseko usebenzisa i-electroplating, indima yayo ayikona nje ukulawula ukuhamba kombhobho ophakathi, kodwa kunye nokudlala indima yokuhombisa. Ivalve engunxantathu idityaniswa ngokubanzi kunye nemibhobho kunye nombhobho wokungena wamanzi kumlomo wamanzi, unikezelo lwamanzi kwindlu yangasese, kwaye idityaniswe nemibhobho kunye nethumbu lokungena lamanzi ukulungiselela unikezelo lwamanzi lwesifudumezi samanzi. Iivalve zesango zisetyenziselwa ukudibanisa imibhobho kunye neemitha zamanzi. Ivalve yebhola yombhobho kunye noqhagamshelo lwesifudumezi-manzi. Ngenxa yokuba i-valve yebhola yokuvula kunye nokuvalwa kulungeleka ngakumbi kune-valve yesango, ininzi yemibhobho kunye nemitha yamanzi idibaniswe yi-valve yebhola. Ukuthengwa kwevalve yoluntu: Iindidi ezahlukeneyo zeevalvu zoluntu kufuneka zikhethwe ngokweemfuno ezahlukeneyo zabasebenzisi: 1. Jonga ngokubonakalayo ivalve xa uthenga, kwaye umphezulu kufuneka ungabina trakoma; Umphezulu we-Electroplating kufuneka ube yi-luster efanayo, kufuneka ubeke ingqalelo ukuba kukho ukuxobulwa, ukuqhekeka, ukuculwa, ukutyhila ezantsi, ukuxobula, amabala amnyama kunye neziphene ezicacileyo zomgodi; Umphezulu wokutshiza kufuneka ulunge, ugudiswe kwaye ufane, ngaphandle kweziphene ezifana nokuxhoma okuhamba kunye nokuvela ngaphantsi. Ezi ziphene ziya kuchaphazela ngqo ubomi benkonzo yevalve. 2. Umsonto wombhobho wevalve udityaniswe nombhobho, isiphene esibonakalayo njengophawu lweconcave, izinyo eliqhekekileyo libonwa kumphezulu womsonto xa ukhetha kwaye uthenge, ngakumbi abo kufuneka baqaphele isikrufu sombhobho wentambo kunye nesinxibelelanisi sivale. ubude obusebenzayo buya kuchaphazela ukuthembeka kokutywinwa, ubude obusebenzayo bentambo yombhobho kufuneka buqaphele xa ukhetha kwaye uthenge. Ngokubanzi i-DN15 intambo yombhobho we-cylinder ubude obusebenzayo malunga ne-10mm. 3. Iivalve zesango kunye neebhola zebhola zivame ukuphawulwa ngoxinzelelo lwegama kumzimba wevalve okanye umqheba, onokukhethwa ngokweemfuno zabo. 4. Xa utshintsha i-valve yesango ekhoyo okanye i-valve yebhola, qiniseka ukuba ubude bayo besakhiwo bucacile ukuze bungakwazi ukufakwa emva kokuthenga. 5. Intambo yombhobho wevalve engunxantathu ineentlobo ezimbini zentambo yangaphakathi kunye nentambo yangaphandle, ngokwemfuno yokukhetha; Yintoni ISAZISO NAKUNJALO Ivalve kanxantathu UKUBA KUKHO I-ALLOY YEZINC EKUKWENZIWA KWIMAKEKEZO NGOKU, LE IXABISO IVALI LIFUNA PHANTSI KUNEMVELISO JIKELELE, KODWA UKURULA KULULA KUYE KUBANGELE UKWAHLUKA. KUFANELE KUBE KUDLA NGOKUKWENZAKALANAYO KWITOLO LEZINTO EZISESIKWENI ZOKWAKHIWA, I-SUPERMARKET KHETHA AND UTHENGE, UMGANGATHO OWO WEMVELISO UNGAQINISEKISA ANGAPHEZULU.
