Ngaba uyayiqonda imigudu emithandathu yofakelo lwevalvu?

I-valve sesona sixhobo sixhaphakileyo kumashishini ekhemikhali. Kubonakala kulula ukufaka iivalve, kodwa ukuba ayilandeli iteknoloji efanelekileyo, iya kubangela iingozi zokhuseleko. Namhlanje ndingathanda ukwabelana nawe ngamava malunga nofakelo lwevalvu.

1. Uvavanyo lwe-Hydrstatic kwiqondo lokushisa elibi ngexesha lokwakhiwa ebusika.
Iziphumo: ngenxa yokuba ityhubhu iqhwala ngokukhawuleza ngexesha lovavanyo lwe-hydraulic, ityhubhu iqhwa.
Imilinganiselo: zama ukwenza uvavanyo lwe-hydraulic ngaphambi kwesicelo sasebusika, kwaye emva kovavanyo loxinzelelo lokuvuthela amanzi, ngakumbi amanzi kwivalve kufuneka asuswe kumnatha, ngaphandle koko i-valve iya kuhlwa, inzima i-crack efriziwe. Iprojekthi kufuneka iqhutywe ebusika, phantsi kweqondo lokushisa elihle langaphakathi, kwaye amanzi kufuneka avuthelwe acoceke emva kovavanyo loxinzelelo.

I-2, inkqubo yepayipi yokuvavanya amandla e-hydraulic kunye novavanyo lokuqina, ukuhlolwa kokuvuza akwanele.
Iziphumo: ukuvuza kwenzeka emva kokusebenza, okuchaphazela ukusetyenziswa okuqhelekileyo.
Amanyathelo: Xa inkqubo yepayipi ivavanywa ngokweemfuno zokuyila kunye neenkcukacha zokwakha, ngaphezu kokurekhoda ixabiso loxinzelelo okanye ukuguqulwa komgangatho wamanzi ngexesha elichaziweyo, ngokukodwa ukujonga ngokucophelela ukuba kukho ingxaki yokuvuza.

3, Ipleyiti yevalvu yebhabhathane enepleyiti eqhelekileyo yevalve.
Iziphumo: butterfly valve flange ipleyiti kunye eqhelekileyo ipleyiti ivalve flange ubungakanani yahlukile, ezinye flange ububanzi yangaphakathi encinane, kunye disc butterfly valve enkulu, okubangela ukuba ayivuleki okanye ivuleke nzima kwaye wenze umonakalo ivelufa.
Imilinganiselo: ipleyiti yeflange kufuneka icutshungulwe ngokobungakanani bokwenene beflange yevalve yebhabhathane.

4. Indlela yokufaka ivalvu ayilunganga.
Umzekelo: ivalve yokukhangela amanzi (umphunga) ichasene nophawu, isikhondo sevalve ifakwe ezantsi, ivalve yokukhangela ethe tye efakelweyo ithathe ufakelo oluthe nkqo, ivalve yesango enyukayo okanyeivalve yebhabhathane ethambileyoisiphatho asivulanga, isithuba esivaliweyo, njl.
Iziphumo: ukusilela kwevalvu, ukugcinwa kweswitshi kunzima, kwaye i-valve shaft ijonge ezantsi ihlala ibangela ukuvuza kwamanzi.
Imilinganiselo: ngokungqongqo ngokwemiyalelo yofakelo lwevalve yofakelo, ivalve yesango evulekileyo ukugcina ivalve yesikhondo sobude bokuvula ubude, ivalve yebhabhathane ithathele ingqalelo ngokupheleleyo indawo yokujikelezisa umqheba, zonke iintlobo zesikhondo sevalve azinakuba ngaphantsi kwendawo ethe tye, siyeke phantsi. .

5. Iinkcukacha kunye neemodeli zevalve efakiweyo azihambelani neemfuno zoyilo.
Ngokomzekelo, uxinzelelo lwe-valve lungaphantsi koxinzelelo lovavanyo lwenkqubo; umbhobho wesebe lamanzi wokutya wamkelaivalve yesangoxa ububanzi bombhobho bungaphantsi okanye bulingana no-50mm; umbhobho wokufunxa impompo yomlilo wamkela ivalve yebhabhathane.
Iziphumo: kuchaphazela ukuvulwa okuqhelekileyo kunye nokuvalwa kwe-valve kunye nokulungelelanisa ukuchasana, uxinzelelo kunye neminye imisebenzi. Nokuba kubangele ukusebenza kwenkqubo, umonakalo wevalve unyanzelekile ukuba ulungise.
Imilinganiselo: Ziqhelanise nomda wokusetyenziswa kweevalvu ezahlukeneyo, kwaye ukhethe ukucaciswa kunye neemodeli zeevalvu ngokweemfuno zoyilo. Uxinzelelo oluncinci lwevalvu luya kuhlangabezana neemfuno zoxinzelelo lovavanyo lwenkqubo.

6. Ukuguqulwa kweValve
Iziphumo:khangela ivalve, i-valve yokunciphisa uxinzelelo kunye nezinye ii-valve zine-directionality, ukuba ifakwe i-inverted, i-valve ye-throttle iya kuchaphazela umphumo wenkonzo kunye nobomi; ivalve yokunciphisa uxinzelelo ayisebenzi konke konke, ivalve yokukhangela iya kubangela ingozi.
Imilinganiselo: ivalve jikelele, enophawu lwendlela kumzimba wevalvu; ukuba akunjalo, kufuneka ichongwe ngokuchanekileyo ngokomgaqo wokusebenza wevalve. Ivalve yesango akufanele iguqulwe (oko kukuthi, ivili lesandla phantsi), kungenjalo iya kwenza i-medium igcinwe kwindawo yebhoncover ixesha elide, kulula ukutshabalalisa i-valve stem, kwaye kunzima kakhulu ukubuyisela indawo yokugcwalisa. Iivalvu zesango lesikhondo ezinyukayo azifaki ngaphantsi komhlaba, kungenjalo zonakalisa isikhondo sevalve evelileyo ngenxa yokufuma.Ivalve yokujonga ujingi, ukufakela ukuqinisekisa ukuba i-pin shaft level, ukwenzela ukuba i-flexible.
