KuyiniI-Ball Valve Encane
A ivalvu encane yebholaiyivalvu yokujika ngekota esebenzisa ibhola elingenalutho, elinezimbobo ukulawula ukugeleza koketshezi. Lapho isibambo sevalvu siphendulwa ngama-degree angu-90, ibhola liyajikeleza ukuze livumelanise imbobo yalo nepayipi (indawo evulekile) noma liyivimbe ngokuphelele (indawo evaliwe). Lawa mavalvu abonakala ngobukhulu bawo obuncane, ukwakheka okulula, kanye nokulula kokusebenza, okwenza afaneleke kakhulu ezindaweni ezixineneyo noma izinhlelo zokusebenza ezidinga ukulungiswa njalo.
Izinzuzo ezibalulekile zama-valve amancane ebhola zifaka:
- Ukuvalwa okuvimbela ukuvuzaukuze kusebenze kahle.
- Ukuvala okusheshayonge-torque encane kakhulu.
- Ukuguquguqukaekuphatheni uketshezi, amagesi, kanye nezinto ezilimazayo.
- Ukunakekelwa okuphansingenxa yokwakhiwa okulula.

Izinhlobo zama-Valve Amancane Ebhola
Amavalvu amancane ebhola atholakala ngemiklamo eyahlukene ukuze avumelane nezinhlelo ezithile. Nazi izinhlobo ezivame kakhulu:
1. I-Thread Ball Valve
A i-valve yebhola yentamboineziphetho ezinentambo (i-NPT, i-BSPP, noma i-BSPT) ukuze kube lula ukufaka emapayipini ngaphandle kokushisela. Lawa mavalvu asetshenziswa kabanzi ekufakweni kwamapayipi ezindaweni zokuhlala, ezinhlelweni zomoya ocindezelwe, kanye nasezinhlelweni zezimboni ezinomfutho ophansi.
2. I-Flange Ball Valve
Amavalvu ebhola le-Flangezineziphetho ezigobile zokuxhumanisa ngamabholidi, ezilungele izinhlelo ezinomfutho ophezulu noma ezinkulu. Zivame kakhulu ezimbonini zikawoyela negesi, zokwelashwa kwamanzi, kanye nezamakhemikhali.
3. Amavalvu Ebhola Lama-PC Ama-2 vs. Amavalvu Ebhola Lama-PC Ama-3
- Amavalvu ebhola ama-PC amabiliinezingxenye ezimbili zomzimba eziyinhloko, okunikeza ibhalansi phakathi kwezindleko kanye nokulungiselelwa.
- Amavalvu ebhola ama-PC amathathuinezingxenye ezintathu zomzimba ezihlukaniswayo, okwenza kube lula ukuqaqa ukuze kuhlanzwe noma kulungiswe ngaphandle kokususa ivalvu epayipini.
4. I-Floating Ball Valve
Phakathi kuivalvu yebhola elintantayo, ibhola libanjwa endaweni yalo ngokucindezelwa okuvela ezihlalweni zamavalvu. Lo mklamo ungabizi kakhulu futhi ufanelekela ukusetshenziswa kokucindezela okuphansi kuya kokuphakathi.

Ukukhetha Izinto Ezibalulekile Zama-Valve Amabhola Amancane
Izinto zevalvu zithinta ukuqina kwayo, ukumelana nokugqwala, kanye nokuhambisana noketshezi. Izinketho ezidumile zifaka:
1. I-Stainless Steel Ball Valve
Amavalvu ebhola lensimbi engagqwali(isb., i-SS304, i-SS316) iphumelela kakhulu ezindaweni ezigqwalisayo, njengokucubungula amakhemikhali, ukusetshenziswa kwasolwandle, noma izinhlelo zokudla.
2. I-Carbon Steel Ball Valve
Amavalvu ebhola lensimbi yekhabhoniziqinile futhi zingabizi, zilungele izinhlelo zokushisa okuphezulu kanye nokucindezela okuphezulu ezindaweni zokuhlanza uwoyela noma iziteshi zikagesi.
3. I-Forged Steel Ball Valve
Amavalvu ebhola lensimbi ahlanganisiweZenziwa ngokusebenzisa ubumba, okuholela ekubeni namandla aphezulu kanye nokumelana nezimo ezimbi kakhulu. Zivame ukusetshenziswa ezisetshenziswa ezimbonini ezisebenza kanzima.

Ukusetshenziswa kwama-Small Ball Valve
- Amapayipi kanye ne-HVAC: Ukulawula ukugeleza kwamanzi ezinhlelweni zokuhlala noma zezentengiselwano.
- Ukucubungula Amakhemikhali: Ukuphatha uketshezi olunamandla ngensimbi engagqwali noma amavalvu afakwe i-PTFE.
- Izimoto: Ukulawulwa kukaphethiloli kanye nokupholisa ezinhlelweni zenjini ezincane.
- Imithi: Ukuqinisekisa ukudluliswa koketshezi oluhlanzekile ngama-valve ebhola ahlanzekile.
- Ezolimo: Ukunisela kanye nokusatshalaliswa komanyolo.

Indlela Yokukhetha I-Valve Yebhola Elincane Elifanele
1. Izilinganiso Zokucindezela Nokushisa: Qinisekisa ukuthi ivalvu ihlangabezana nemikhawulo yokusebenza kwesistimu yakho.
2. Uhlobo Lokuxhumeka: Khetha iziphetho ezinentambo, ezigoqekile, noma ezihlanganisiwe ngokusekelwe ezidingweni zokufakwa.
3. Ukuhambisana kwezinto ezibonakalayo: Qondanisa umzimba wevalvu nezinto zokuvala nohlobo loketshezi (isb., izivalo ze-PTFE zamakhemikhali).
4. Usayizi weValve: Qinisekisa ukuthi usayizi wephothi (isb., ¼” kuya ku-2”) uhambisana nobukhulu bephayiphi yakho.
5. Izitifiketi: Funa izindinganiso zemboni ezifana ne-API, i-ANSI, noma i-ISO ukuze uqiniseke ngekhwalithi.

Imibuzo Evame Ukubuzwa Mayelana Nama-Small Ball Valve
U: Uyini umehluko phakathi kwevalvu yebhola elincane nevalvu yebhola ejwayelekile
A: Amavalvu ebhola amancanezincane ngobukhulu (ngokuvamile zingaphansi kobubanzi obungu-1”) futhi zenzelwe ukusetshenziswa okugeleza kancane noma okunembile, kanti ama-valve ebhola ajwayelekile anakekela izinhlelo ezinkulu.
Q: Ingabe ivalvu yebhola yensimbi engagqwali ingaphatha amanzi olwandle?
A: Yebo, amavalvu ensimbi engagqwali e-SS316 anikeza ukumelana okuhle kakhulu nokugqwala ezindaweni zasolwandle.
U: Kufanele ngikhethe nini ivalvu yebhola enama-PC amathathu kuneyama-PC amabili
A: Khetha i-I-valve yebhola yama-PC ama-3uma kudingeka ukulungiswa noma ukuhlanza njalo, njengoba kuvumela ukufinyelela kalula ezingxenyeni zangaphakathi.
