Ubungakanani kunye nomthamo wokuqukuqela

Ukukhetha ubungakanani obufanelekileyo

Ukulinganisa Ububanzi bombhobho

Ukukhetha ubungakanani obuchanekileyo boMLILO we-HYDRANT VALVE kuqala ngokulinganisa ngokuchanekileyo i-diameter yombhobho. Ndihlala ndincoma ukusebenzisa iindlela eziqhelekileyo zokuqinisekisa ukuchaneka. Ngokomzekelo, iI-DN (I-Diameter Nominal)inkqubo ilinganisa i-diameter yangaphakathi kwiimilimitha, ngelixa iI-NPS (Ubungakanani boMbhobho oQelekileyo)inkqubo isebenzisa i-intshi ngokusekelwe kwidayamitha yangaphandle. Enye indlela ethembekileyo ibandakanya umlinganiselo wesangqa sombhobho kunye nokwahlulahlula ngo-π (pi). Ngokomzekelo, i-circumference ye-12.57 intshi ihambelana ne-4-intshi ububanzi. Le theyibhile ingezantsi ishwankathela ezi ndlela:

Imilinganiselo echanekileyo iqinisekisa ukuba i-valve ingena ngokungenamthungo kwisistim, ukuphepha ukulungiswa kweendleko kamva.

Ukubala iiMfuno zokuHamba

Emva kokumisela ubungakanani bombhobho, ndibala iimfuno zokuhamba ukuze ndikhethe i-valve ehlangabezana neemfuno zenkqubo. Iinjineli zihlala zisebenzisa i-flow coefficient (Cv) formula:

Cv = Q * sqrt(SG / P)

Apha, i-Q imele izinga lokuhamba kwiigaloni ngomzuzu (GPM), i-SG yi-gravity ethile ye-fluid, kunye ne-P yi-pressure drop in pounds per square inch (psi). Ivalve enexabiso leCv elilingana okanye elingaphezulu kwexabiso elibaliweyo liqinisekisa ukusebenza kakuhle. Olu balo lunceda ukugcina ukusebenza kakuhle kunye nokuthintela uxinzelelo lwenkqubo.

Ezi ziqinisekiso ziqinisekisa ukukwazi kwevalve ukwenza phantsi koxinzelelo kunye nokuthobela imigangatho yokhuseleko. Ukuhlolwa rhoqo kunye novavanyo luqinisekisa ukuba i-valve ihlala isebenza kwaye ilungele iimeko zikaxakeka.

Ingcebiso: Ngalo lonke ixesha qinisekisa ukuba i-valve ihlangabezana nemigangatho yoshishino kunye nemimiselo yendawo ukuqinisekisa ukuba inkqubo ekhuselekileyo nethobelayo.

Ukukhetha i-valve yeHydranti yoMlilo eyiyo kufuna uqwalaselo ngononophelo lwemiba emininzi ebalulekileyo. Ukuphinda:

1. Uhlobo lweValve kunye nobukhulu: Qinisekisa uhlobo lwevalvu kunye nobukhulu bulungelelaniswa neemfuno zesixokelelwano sakho ukuze usebenze ngokugqibeleleyo.
2. Izinto eziphathekayo kunye noKuhlala ixesha elide: Khetha izixhobo ezimelana neemeko zokusingqongileyo kwaye uqinisekise ukuthembeka kwexesha elide.
3. Amanqaku oxinzelelo: Tshatisa iklasi yoxinzelelo lwevalvu kunye neemeko zokusebenza zesixokelelwano sakho.
4. Ukuhambelana: Qinisekisa ukuba isivalo sidibana ngokungenamthungo kunye neziseko ezingundoqo ezikhoyo.
5. UkuLula kweSondlo: Khetha iivalvu ezinoyilo olusebenziseka lula kunye neemfuno zokugcinwa kancinci.
6. Ukuthobela: Qinisekisa ukuthotyelwa kwemigangatho yoshishino kunye nemimiselo yendawo.

Ukubonisana neengcali okanye abavelisi abathembekileyo bayenza lula le nkqubo. Iingcali zinokukukhokela ekukhetheni iivalvu ezilungiselelwe iimfuno zenkqubo yakho, ziqinisekisa ukhuseleko kunye nokusebenza kakuhle. Ukuqonda kwabo malunga nokuhambelana kwezinto, iiklasi zoxinzelelo, kunye neentlobo zokudibanisa zinceda ukuphepha iimpazamo ezibiza kakhulu. Ngokubeka phambili le miba, unokukhetha ngokuzithemba i-valve ehambisa ukusebenza okuthembekileyo ngexesha likaxakeka.

FAQ

Yintoni eyona nto ibalulekileyo xa ukhetha ivalve yombhobho womlilo?

Eyona nto ibaluleke kakhuluukuhambelana nenkqubo yakho. Ndihlala ndiqinisekisa ukuba ivalve ihambelana nobungakanani bombhobho, iimfuno zoxinzelelo, kunye nohlobo lokudibanisa. Oku kuqinisekisa ukuhlanganiswa okungenamthungo kunye nokusebenza okuthembekileyo ngexesha likaxakeka.

Kufuneka zigcinwe kangaphi iivalvu zesixhobo sokucima umlilo?

Ndincoma ukuhlola nokugcina iivalve zombhobho womlilo ubuncinane kanye ngonyaka. Ukuhlolwa rhoqo ukuvuza, ukubola, kunye nokunxiba kuqinisekisa ukuba ivalve ihlala isebenza kwaye ilungele iimeko zikaxakeka.

Ngaba ndingasebenzisa isivalo esifanayo kumashishini kunye neenkqubo zokuhlala?

Hayi, iinkqubo zoshishino kunye neendawo zokuhlala zineemfuno ezahlukeneyo. Iinkqubo zoshishino zifuna iivalve ezinamandla zoxinzelelo oluphezulu kunye nomthamo, ngelixa iinkqubo zokuhlala zibeka phambili ukukhululeka kokusetyenziswa kunye nokuphumelela kweendleko. Ndihlala ndikhetha iivalve ngokusekelwe kwisicelo esithile.

Kutheni ukukhetha imathiriyeli kubalulekile kwiivalvu zombhobho womlilo?

Izinto eziphathekayo zichaphazela ukuqina, ukuxhathisa ukubola, kunye nokusebenza. Ngokomzekelo, insimbi engenasici isebenza kakuhle kwiinkqubo zoxinzelelo oluphezulu, ngelixa ubhedu okanye ubhedu lufanelekile ukusetyenziswa ngokubanzi. Ndihlala ndikhetha imathiriyeli ehambelana neemfuno zemo engqongileyo nezokusebenza kwenkqubo.

Ngaba zonke iivalvu zesixhobo sokucima umlilo ziyahambelana nemigangatho yokhuseleko?

Ayizizo zonke iivalvu ezihlangabezana nemigangatho yokhuseleko. Ndihlala ndiqinisekisa ukuba ivalve ihambelana ne-API, i-JIS, okanye imigangatho ye-BS kwaye ithobela iikhowudi zokhuseleko lomlilo zendawo. Oku kuqinisekisa ukuthembeka kunye nokuthotyelwa komthetho.

Ingcebiso: Soloko udibana neengcali okanye abavelisi abathembekileyo ukuqinisekisa ukuba ivalve ihlangabezana nazo zonke iziqinisekiso eziyimfuneko.
