Amavalvu ebholaziyizingxenye ezibalulekile ezinhlelweni zokulawula uketshezi, ezinikeza ukuvalwa okuthembekile kanye nokulawulwa kokugeleza. Phakathi kwemiklamo eyahlukahlukene,amavalvu ebhola anentamboZivelele ngokufakwa kwazo okulula kanye nokuguquguquka kwazo. Lesi sihloko siyachazaiyini ivalvu yebhola, yayoukuhlukaniswa, izinhlelo zokusebenza, futhiizitayela zemakethe, kugxilwe kakhulu kumamodeli adumile afana ne-I-valve yebhola enezingcezu ezimbili, I-valve yebhola yethusi engu-2 intshi, futhiI-valve yebhola engu-2in.
Iyini i-Ball Valve
Ivalvu yebhola isebenzisa ibhola eliyimbobo, elijikelezayo elinembobo ukulawula ukugeleza koketshezi. Lapho imbobo yebhola ihambisana nepayipi, uketshezi lugeleza ngokukhululeka; ukujika kwamadigri angu-90 kuvimbela ukugeleza ngokuphelele. Amavalvu ebhola anemicu anezixhumi zesikulufo (izintambo ze-NPT noma ze-BSP), okwenza zilungele izinhlelo zokucindezela eziphansi kuya kweziphakathi kumapayipi, i-HVAC, kanye nezindawo zezimboni.
Izingxenye ezibalulekile zifaka:
- Ibhola: Insimbi engagqwali, Insimbi yekhabhoni (A105N, WCB), ithusi, noma i-PVC.
- Izihlalo: I-PTFE noma irabha yokuvala.
- Isiqu: Ixhuma isibambo nebhola.
- Umzimba: Ngokuvamile kwenziwa ngethusi, insimbi engagqwali, noma insimbi eyenziwe ngobumba.
Ukuhlukaniswa kweAmavalvu Ebhola
Amavalvu ebhola ahlukaniswe ngokwedizayini, izinto zokwakha, usayizi, kanye nohlobo lokuxhuma. Ngezansi kunezinhlobo ezivamile ezihambisana namavalvu ebhola anezintambo:
1. Ngesakhiwo
- Ama-valve ebhola amabili: Umklamo womzimba onezingxenye ezimbili (umzimba + isivalo sokugcina) ukuze kube lula ukuwunakekela. Usetshenziswa kabanzi ezinhlelweni zamanzi zasemakhaya.
- I-Valve Yebhola Eyizingxenye Ezi-3: Ihlukaniswa ngokuphelele ukuze ihlanzwe noma ilungiswe, okuvamile ezisetshenziswa ezimbonini.
2. Ngosayizi
- I-valve yebhola engu-2 intshi: Ivalvu ephakathi nendawo efanelekela amapayipi amanzi, igesi, noma uwoyela.I-valve yebhola yethusi engu-2 intshiithandwa ngenxa yokumelana kwayo nokugqwala.
- I-valve yebhola engu-2in: Uhlobo oluncane lwezindawo ezixineneyo, oluvame ukusetshenziswa ezintweni zikagesi noma ezinhlelweni ezincane.
3. Ngokwezinto Ezibalulekile
- Amavalvu Ebhola Lethusi: Ishibhile futhi ayigqwali.Ama-valve amabili ebhola lethusifuthiI-valve yebhola yethusi engu-2inziyizinto eziyisisekelo ekufakeni amapayipi.
- Amavalvu Ebhola Lensimbi Engagqwali: Kwezindawo ezinomfutho ophezulu noma ezigqwalisayo.
4. Ngokuxhumeka
- I-Threaded Ball Valve: Ifaka imicu yezikulufo (i-NPT, i-BSP) yokufaka engavuzi. Izibonelo zifaka phakathiI-valve yebhola enezintambo ezimbilikanye no-tivalvu yebhola yentambo.
- I-Flanged Ball Valve: Kwamapayipi ezimboni asebenza kanzima.
Ukusetshenziswa kwama-Threaded Ball Valve
Ama-valve ebhola anezintambo asetshenziswa kabanzi ngenxa yobulula nokuqina kwawo:
1. Ukufakwa Kwamapayipi Ezindlu
- Ivalvu Yamanzi engu-2 intshi: Ilawula ukutholakala kwamanzi emakhaya.
- Amavalvu ebhola lethusi ama-2: Isetshenziswa ezinhlelweni zokushisa noma ompompi bangaphandle.
2. Izinhlelo Zezimboni
- Ama-valve ebhola amabili: Uphatha uketshezi ezindaweni zokucubungula amakhemikhali noma zokuhlanza uwoyela.
- Ivalvu Enentambo: Ixhuma amapayipi emoyeni ocindezelwe noma emigqeni yomusi.
3. Ukusetshenziswa Kwezentengiselwano
- I-valve yebhola engu-2in: Ilawula ukugeleza kwamanzi ezindaweni zokudlela noma emahhotela.
- Amavalvu Amabhola Ama-2: Kulungele izinhlelo zokunisela noma amanethiwekhi okucima umlilo.
Umbono Wemakethe Wama-Ball Valve
Imakethe yama-ball valve omhlaba wonke kulindeleke ukuthi ikhule kancane kancane, iqhutshwa yi:
1. Ukuthuthukiswa Kwengqalasizinda: Isidingo esikhulayo sezitshalo zokuhlanza amanzi kanye namapayipi kawoyela/igesi.
2. Okuthandwayo ngama-Brass Valve: II-valve yebhola yethusi engu-2 intshifuthiAma-valve amabili ebhola lethusizibusa izimakethe zezindlu ngenxa yokusebenzisa kahle izindleko.
3. Ukuzenzekela Kwezimboni: Ama-valve asebenza kahle kakhulu afanaI-valve yebhola enezintambo ezimbilizibalulekile ezinhlelweni zokukhiqiza ezihlakaniphile.
4. Umkhuba Wokuzinza: Izinto ezingamelani nokugqwala (isb., insimbi engagqwali, ithusi) zandisa isikhathi sokuphila kwevalvu, zinciphisa imfucuza.
Amavalvu ebhola anentambo, ikakhulukaziI-valve yebhola yethusi engu-2infuthiI-valve yebhola engu-2 intshiamamodeli, azohlala ethandwa ngenxa yokulula kwawo ukufakwa kanye nokuzivumelanisa nezimo.
Indlela Yokukhetha I-Threaded Ball Valve Efanele
1. Uhlobo LoketsheziSebenzisa ithusi emanzini/igesi kanye nensimbi engagqwali yamakhemikhali.
2. Isilinganiso Sokucindezela: Qinisekisa ukuthi ivalvu iyahlangabezana nezidingo zokucindezela kwesistimu.
3. Usayizi: AIvalvu yamanzi engu-2 intshiifanele amapayipi ajwayelekile, kuyilaphoI-valve yebhola engu-2inifanelana nezilungiselelo ezincane.
4. Izitifiketi: Bheka ukuhambisana kwe-NSF, ANSI, noma i-ISO.
Isiphetho
Amavalvu ebhola anentambo, njengeI-valve yebhola enezingcezu ezimbili, I-valve yebhola yethusi engu-2 intshi, futhii-valve yebhola yentambo, zibalulekile kakhulu ezinhlelweni zokulawula uketshezi zesimanje. Ukuguquguquka kwazo, ukuqina kwazo, kanye nokulula kokufakwa kwazo kuzenza zilungele ukusetshenziswa kwezindlu, ezentengiselwano, kanye nezimboni. Njengoba ingqalasizinda kanye nokwenza izinto ngokuzenzakalela kuthuthuka, isidingo samavalvu asebenzayo nathembekile—ikakhulukaziI-valve yebhola yethusi engu-2infuthiI-valve yebhola enezintambo ezimbili—izoqhubeka nokuphakama.
Ngokuqonda izinhlobo zazo, ukusetshenziswa kwazo, kanye nemikhuba yemakethe, amabhizinisi kanye nabanini bezindlu bangathuthukisa izinhlelo zabo ukuze zisebenze kahle futhi zihlale isikhathi eside.
