Ubona kubhalwe “i-union valve” kanye “ne-ball valve”, kodwa ingabe zihlukile? Ukukhetha okungalungile kusho ukuthi kungadingeka usike i-valve enhle kakhulu kamuva ukuze ulungise iphampu.
Ivalvu yebhola ichaza indlela yokuvala (ibhola). I-union ichaza uhlobo lokuxhumana oluvumela ukususwa (ama-union nuts). Azihlukani; ivalvu eguquguqukayo kakhulu yi-i-valve yebhola yomanyano weqiniso, okuhlanganisa zombili izici.
Lokhu kungenye yezinto ezivame kakhulu ukudideka engizibonayo, futhi kuwumehluko obalulekile kunoma yimuphi uchwepheshe. Ngivame ukuxoxa ngalokhu nomlingani wami uBudi e-Indonesia, ngoba amakhasimende akhe adinga izixazululo ezingasebenzi nje kuphela kodwa futhi ezisebenza kahle ukuze zigcinwe isikhathi eside. Iqiniso liwukuthi, la magama achaza izinto ezimbili ezahlukene: eyodwa ikutshela.Kanjaniivalvu iyasebenza, kanti enye ikutshelaukuthi ixhumana kanjanikupayipi. Ukuqonda lo mehluko kubalulekile ekuklameni uhlelo oluhlakaniphile nolulungisekayo.
Uyini umehluko phakathi kwevalvu yebhola nevalvu yebhola yomanyano?
Ufake i-valve yebhola ejwayelekile, uyinamathelisa unomphela entanjeni. Ngemva konyaka, uphawu luyaphela, bese uqaphela ukuthi okuwukuphela kwenketho yakho ukusika i-valve yonke bese uqala kabusha.
I-valve yebhola ejwayelekile iyiyunithi eyodwa, efakwe unomphela. I-valve yebhola yomanyano weqiniso inamantongomane anezintambo akuvumela ukuthi ususe umzimba we-valve ephakathi ngaphandle kokusika ipayipi, okwenza ukulungiswa noma ukushintshwa kube lula.
Lona umehluko obaluleke kakhulu wokuhlela isikhathi eside. Cabanga ngakho ngokuthi “okuhlala njalo” uma kuqhathaniswa nokuthi “okulungisekayo.” Ivalvu yebhola ejwayelekile, encane ifakwa ngqo epayipini. Uma isifakiwe, iyasebenza unomphela. Lokhu kulungile emigqeni elula, engabalulekile. Ai-valve yebhola yomanyano weqinisoNokho, yenzelwe ikusasa. Uhlanganisa izingcezu ezimbili zangemuva ezihlukene epayipini, bese umzimba wevalvu oyinhloko uhlala phakathi kwazo. Ubanjwe yizinhlayiya ezimbili ezinkulu ze-union. Uma kwenzeka udinga ukufaka izivalo zevalvu noma umzimba wonke, umane ukhulule izinhlayiya bese uziphakamisa. Yingakho thina kwa-Pntek silwela umklamo we-union wangempela; uguqula ukulungiswa okukhulu kube umsebenzi olula wemizuzu emi-5.
I-Valve Yebhola Elijwayelekile vs. I-True Union
| Isici | I-Ball Valve Ejwayelekile (Encane) | I-True Union Ball Valve |
|---|---|---|
| Ukufakwa | Ihlala njalo (ifakwe i-solvent-welded) | Ingalungiseka (ama-union nuts) |
| Ukulungiswa | Kudinga ukusika ipayipi | Ukususwa komzimba ukuze kube lula ukulungisa |
| Izindleko Zokuqala | Ngaphansi | Okuphakeme |
| Inani Lesikhathi Eside | Ukulungiswa okuphansi (okubizayo) | Okuphakeme (konga isikhathi kanye nomsebenzi) |
Iyini i-valve yokuhlanganisa?
Ubona igama elithi “i-union valve” bese ucabanga ukuthi liyisigaba esihluke ngokuphelele, njenge-gate valve noma i-check valve. Lokhu kungabaza kungakuvimbela ekukhetheni inketho ewusizo kakhulu.
I-valve yokuhlanganisa akuyona uhlobo lomshini, kodwa uhlobo lokuxhuma. Yinoma yiliphi i-valve esebenzisa izinto zokuhlanganisa (amantongomane anezintambo) ukuxhuma umzimba we-valve emaphethelweni epayipi, okuvumela ukususwa kalula.
“I-union” ngokwayo iyingcezu yobunjiniyela ehlakaniphile. Yakhiwe izingxenye ezintathu eziyinhloko: izingcezu ezimbili zangemuva ezixhumanisa nepayipi (kungaba nge-solvent weld noma ngentambo), kanye ne-nut enentambo ezidonsa ndawonye ukuze zenze uphawu.ivalvu yomanyano"Kumane kwakha lesi sici ekwakhiweni kwevalvu. Ngakho-ke, ungaba nevalvu yebhola le-union yangempela, ivalvu yokuhlola i-union yangempela, noma ivalvu ye-union diaphragm yangempela. Inhloso ihlala ifana:ukusebenziseka kahle. Ikuvumela ukuthi uhlukanise futhi ususe umshini ngaphandle kokucindezela uhlelo lonke noma, okubaluleke kakhulu, ngaphandle kokusika ipayipi lakho. Le ndlela yokulinganisa iyisisekelo somklamo wamapayipi wesimanje, ophumelelayo kanye nengxenye eyinhloko yefilosofi "yokuwina wonke umuntu" engiyabelana ngayo nabalingani abanjengoBudi. Isindisa isikhathi nemali kumakhasimende akhe phakathi nesikhathi sokuphila kohlelo.
Yiziphi izinhlobo ezintathu zama-valve?
Ubulokhu usebenzisa ama-ball valve kukho konke, kodwa uhlelo olulodwa ludinga ukulawulwa okuqondile kokugeleza. Uzama ukuvala kancane i-ball valve, kodwa kunzima ukuyilawula futhi uzwa umsindo ongajwayelekile.
Izinhlobo ezintathu eziyinhloko zama-valve ezisebenzayo yi-Shut-Off (On/Off), i-Throttling (Regulating), kanye ne-Non-Return (Backflow Prevention). Uhlobo ngalunye lwenzelwe umsebenzi ohlukile ngokuphelele, futhi ukusebenzisa olungalungile kungalimaza uhlelo lwakho.
Ukwazi izigaba eziyisisekelo kubalulekile ekukhetheni ithuluzi elifanele lomsebenzi. Ukusebenzisa ivalvu engalungile kuyiphutha elivamile kakhulu. Ivalvu yebhola iyi-ivalvu yokuvala; iklanyelwe ukuba ivuleke ngokuphelele noma ivalwe ngokuphelele. Ukuyisebenzisa ukuze i-throttle flow ingabangela ukuphazamiseka okulimaza ibhola nezihlalo, okubangela ukuthi yehluleke.
Kuchazwe Izigaba Zevalvu
| Uhlobo lwe-Valve | Umsebenzi Oyinhloko | Izibonelo Ezivamile | Ikesi Lokusetshenziswa Elingcono Kakhulu |
|---|---|---|---|
| Ukuvala (Kuvuliwe/Kuvaliwe) | Ukumisa ngokuphelele noma ukuvumela ukugeleza. | Ivalvu Yebhola, Ivalvu Yesango, Ivalvu Yebhabhathane | Ukuhlukanisa izingxenye noma imishini. |
| Ukugoqa (Ukulawula) | Ukulawula isivinini noma ukucindezela kokugeleza. | Ivalvu Yembulunga, Ivalvu Yenaliti | Ukubeka izinga lokugeleza eliqondile. |
| Ukungabuyi (Ukubuyela Emuva) | Ukuvumela ukugeleza ohlangothini olulodwa kuphela. | I-Check Valve, I-Foot Valve | Ukuvikela iphampu ekugelezeni kwamanzi emuva. |
Yiziphi izinhlobo ezine zama-ball valve?
Uyazi ngama-valve e-union angempela, kodwa ubona ezinye izinketho ezifana nokuthi “i-compact” noma “i-one-piece.” Awuqiniseki ukuthi yikuphi okungcono kakhulu kwezinye izinhlelo zokusebenza, futhi ungase ukhokhe kakhulu ngezici ongazidingi.
Izinhlobo ezine eziyinhloko zamavalvu ebhola zihlukaniswa ngokwakhiwa komzimba: Ucezu Olulodwa (oluvaliwe), Ucezu Olubili (umzimba onentambo), Ucezu Oluthathu (njengobumbano lwangempela), kanye no-Compact (umklamo olula, ongabizi, ngokuvamile oyingxenye eyodwa).
Nakuba indlela yangaphakathi yokusebenza ifana (ibhola elijikelezayo), indlela umzimba owakhiwe ngayo inquma izindleko kanye nokulungiselelwa kwawo. Ezweni le-PVC, sigxila kakhulu ekwakhiweni kwe-union enengxenye eyodwa/encane kanye nengxenye ezintathu/yeqiniso.
- Ucezu olulodwa /I-Compact Ball Valve:Umzimba wevalvu uyiyunithi eyodwa, evaliwe. Lona umklamo ongabizi kakhulu. Ulula, ulula, futhi uphelele ukusetshenziswa lapho ukulungiswa kungeyona inkinga futhi izindleko kuyimbangela eyinhloko.
- I-Two-Piece Ball Valve:Umzimba wenziwe ngezicucu ezimbili ezihlanganisa ibhola ndawonye, zibambe ibhola bese zivala ngaphakathi. Lokhu kuvumela ukulungiswa okuthile kodwa ngokuvamile kudinga ukulisusa emgqeni. Kuvame kakhulu kuma-valve ensimbi.
- Izingcezu Ezintathu (I-True Union) I-Ball Valve:Lona umklamo wekhwalithi ephezulu. Uqukethe izixhumi ezimbili zokugcina (izingcezu zangemuva) kanye nomzimba ophakathi. Lokhu kuvumela umzimba oyinhloko ukuthi ususwe ukuze ulungiswe noma ushintshwe ngaphandle kokuphazamisa ipayipi. Lona ukukhetha okuthembekile kakhulu futhi okungabizi kakhulu kwezicelo ezibalulekile esikhathini eside.
Kwa-Pntek, sigxile ekuhlinzekeni ngemikhiqizo esezingeni eliphezulu kanye ne-compact.ama-valve e-union yangempela, okunikeza ozakwethu abanjengoBudi izinketho ezifanele zanoma yisiphi isidingo samakhasimende.
Isiphetho
I-valve yebhola iyindlela yokusebenza; i-union iwuxhumano. I-union ball valve yangempela iyawahlanganisa, inikeza ukulawula okuphezulu kanye nokugcinwa okulula kwanoma yiluphi uhlelo lobuchwepheshe bamapayipi.
