Iivalvu zeBhola ezineFlanged vs. Threaded: Isikhokelo soKhetho

Ukhetho phakathi kweivalvu yebhola ejikeleziweyokunyeivalvu yebhola eneentambosisigqibo sobunjineli esisisiseko esidlulela ngaphaya kohlobo lonxibelelwano nje kuphela. Sichaphazela ngokuthe ngqo ukuthembeka, ukhuseleko, umjikelo wolondolozo, kunye neendleko zizonke zenkqubo yakho yokuhambisa imibhobho. Nangona iindleko kunye nokulula kudla ngokuba zizinto zokuqala eziqhubayo, ukuqonda okunzulu iimpawu zokusebenza kubalulekile ekukhetheni okufanelekileyo.

Esi sikhokelo sidlula ngaphaya kothelekiso olusisiseko ukuze sinike isakhelo esineenkcukacha zohlalutyo, sikuncede ucacise uqhagamshelo olufanelekileyo lwevalvu kwiimfuno zakho ezithile zoxinzelelo, ulondolozo, kunye nokusebenza.

Ifilosofi yoYilo oluPhambili: Ehlala ihleli vs. Enokulungiseka

Umahluko usekelwe kumjikelo wobomi obucwangcisiweyo kunye nokusebenza kakuhle kwenkqubo.

Iivalvu zeBhola eziQokelelweyo: Isisombululo esiQokelelweyo nesiSigxina

Aivalvu yebhola eneentamboisebenzisa imisonto yeNational Pipe Taper (NPT) ukukrufula ngqo kwipayipi. Uyilo lwemisonto olunciphileyo lwenza i-wedge esuka kwisinyithi ukuya kwisinyithi ethi, ngoncedo lwesitywini, ithintele ukuvuza. Le filosofi yoyilo ithanda i-compact, engabizi kakhulu, kwayeukufakelwa okusisigxina kakhuluapho kungalindelwanga ukuba kuqhekeke khona.

Iivalvu zeBhola eziFlanged: Isisombululo esiSebenza ngokuPhezulu nesiSebenzayo

Aivalvu yebhola ejikeleziweyoineeflanges ezenziwe ngomatshini ezibotshelelwe kwiiflanges zepayipi ezifanayo, kunye negasket ecinezelweyo phakathi kwazo ukwenza isitywino. Olu yilo lwenzelweiinkqubo ezisemgangathweni ophezulu, ezilungisekayo, nezinemodyuliIvumela ukufakwa, ukususwa, kunye nokuhlolwa okulula ngaphandle kokutshintsha inkqubo, nto leyo eyenza ukuba ibe yeyona isemgangathweni kwizicelo ezibalulekileyo.

Uthelekiso loHlalutyo: Ukusebenza phantsi koxinzelelo

Uluhlu olulula lwezinto ezilungileyo nezingalunganga alwanelanga. Nantsi inkcazo-manani yezinto ezibalulekileyo zokusebenza ezisekelwe kwidatha.

1. Uxinzelelo kunye noBume bobushushu

• Uqhagamshelo olunemisonto: Le misonto ngokwayo yindawo enokubangela ukusilela phantsi koxinzelelo. Inokuqhekeka ngenxa yoxinzelelo kwaye inokuvuza phantsi komjikelo omkhulu wobushushu. Ifanelekile kakhulu kwiUvavanyo lweKlasi 800 nangaphantsi, ngesiqhelo kwizicelo eziphantsi200-300 PSI.
• Uqhagamshelo oluFingileyo: Uqhagamshelo olunebholiti lusasaza umthwalo ngokulinganayo, kwaye isitywina segasket esijongene ubuso ngobuso siqinile kakhulu. Yenzelwe iiklasi zoxinzelelo ezimiselweyo (i-ANSI Class 150, 300, 600, 900, 1500, 2500), iivalvu ezijijekileyo ziphatha ngokuthembekileyo uxinzelelo oludlula i-1000 PSI kunye nolwelo olushushu kakhulu.

2. Ukufakelwa, Ukugcinwa, kunye neendleko ezipheleleyo zobunini (TCO)

Ivalvu Enemisonto TCO:

• Ufakelo:Ukufakwa kokuqala ngokukhawuleza; kufuna isitywini kunye nendlela efanelekileyo yokuluka.
• Ulondolozo:Eyona ngxaki iphambili. Ukuqhaqha kudla ngokufuna umva ivalvu kumbhobho, into engenakwenzeka ngenxa yokugqwala okanye ukulungelelaniswa kwenkqubo, nto leyo enyanzelisa ukunqunyulwa kwemibhobho okubiza kakhulu.
• I-TCO:Iindleko zokuqala eziphantsi, kodwa zinokubangela iindleko zokulungisa ezinde ixesha elide.

Ivalvu Ejijekileyo TCO:

• Ufakelo:Kunzima ngakumbi; kufuna ukhetho oluchanekileyo lwe-gasket, ulandelelwano lokuqinisa ibolt, kunye namaxabiso e-torque.
• Ulondolozo:Ayinakulinganiswa. Ivalvu ingavulwa ize iphakanyiswe ngqo ukuze ilungiswe, itshintshwe, okanye ihlolwe, nto leyo enciphisa ixesha lokungasebenzi kwenkqubo.
• I-TCO:Utyalo-mali lokuqala oluphezulu (iivalvu, iigasket, iibholiti), kodwa iindleko zokugcina ubomi bonke kunye nexesha lokungasebenzi ziphantsi kakhulu kwiinkqubo ezibalulekileyo.

3. Ukunyaniseka kwenkqubo kunye nokufaneleka kwesicelo

Iivalvu Ezinemisonto ze-Excel Kwi:

• Ubungakanani: Iipayipi ezincinci ezibophayo (**)

Iivalvu Ezinemisonto ze-Excel Kwi:

• Ubukhulu: Iipayipi ezincinci (iisentimitha ezimbini nangaphantsi).
• Izicelo: Imibhobho yamanzi yokuhlala, i-HVAC, imigca yamanzi/yomoya enoxinzelelo oluphantsi, izixhobo ze-OEM, kunye neenkqubo zokujova iikhemikhali apho indawo incinci khona.
• Indalo: Iinkqubo ezizinzileyo ezinomnyikimo omncinci kunye nokujikeleza kobushushu obuncinci.

Iivalvu ezijijekileyo zibalulekile kwezi zinto zilandelayo:

• Ubungakanani: 2 intshi nangaphezulu (eqhelekileyo), nangona isetyenziswa rhoqo ukuya kuthi ga kwi 1/2″ xa kusenziwa inkonzo ebalulekileyo.
• Izicelo: Ukuveliswa kweoyile negesi, ukucutshungulwa kweekhemikhali, ukuveliswa kombane, izixhobo zokukhusela umlilo, iinkqubo zomphunga, kunye nayo nayiphi na inkqubo enemidiya enobungozi.
• Okusingqongileyo: Iinkqubo ezinokungcangcazela okuphezulu, ukunyuka koxinzelelo, ukwanda kobushushu, okanye ezifuna ukuhlukaniswa rhoqo.

I-Decision Matrix: Ukukhetha uQhagamshelo oluLungileyo

Ngaphaya Kwezinto Ezisisiseko: Izinto Ezibalulekileyo Omele Uziqwalasele Xa Ukhetha

• Ukukhethwa kweGasket: Kwiivalvu ezijijekileyo, igasket iyinto ebalulekileyo esetyenziswayo. Izinto (umz., i-EPDM, i-PTFE, iGraphite) kufuneka zihambelane nolwelo, ubushushu kunye noxinzelelo.
• Ukufakwa Okufanelekileyo: Imisonto ye-NPT kufuneka ivalwe ngokufanelekileyo nge-thread compound okanye iteyipu. Amalungu adibeneyo kufuneka aboshwe ngebholiti kusetyenziswa ulandelelwano lwe-cross-pattern torque ukuqinisekisa ukuba i-gasket icinezelekile kwaye ithintele ukuvuza.
• Ukuhambelana kwezinto: Qinisekisa ukuba izinto zomzimba wevalvu (i-WCB, i-CF8M, njl.njl.) kunye ne-trim ziyahambelana nolwelo lwenkqubo yakho ukuze kuthintelwe ukugqwala kwe-galvanic okanye ukuwohloka kweekhemikhali.

Isiphelo: Umbuzo weFilosofi yeNkqubo

Ingxoxo exutyiweyo kunye nengxoxo exutyiweyo ayithethi ukuba yeyiphi engcono, kodwa yeyiphi efanelekileyo kwifilosofi yenkqubo yakho.

• Khetha ivalvu yebhola eneentambo ukuze ufumane izisombululo ezingabizi kakhulu, ezincinci, nezinokuhlala ixesha elide kwiinkonzo zoxinzelelo oluphantsi ukuya koluphakathi.
• Khetha ivalvu yebhola ejijekileyo xa ufuna usetyenziso oluphezulu, olubalulekileyo, okanye olufuna ukulungiswa apho ukuthembeka kwenkqubo, ukhuseleko, kunye nokuguquguquka kokusebenza kubaluleke kakhulu.

Kwi-NSW Valve, sinikezela okungaphezulu nje kweevalvu; sinikezela ngobuchule. Iqela lethu lobunjineli linokukunceda uqonde ezi zinto ukuze ucacise isisombululo sevalvu esifanelekileyo, ukuqinisekisa ukuthembeka nokusebenza kakuhle ukusuka kuyilo ukuya ekusebenzeni.
