Ubona “i-valve ye-union” kanye “ne-valve yebhola” esohlwini, kodwa ingabe ahlukile? Ukukhetha okungalungile kusho ukuthi kungase kudingeke unqamule i-valve ekahle ngokuhamba kwesikhathi ukuze nje usevise iphampu.
I-valve yebhola ichaza indlela yokuvala (ibhola). Inyunyana ichaza uhlobo lokuxhuma oluvumela ukususwa (amantongomane enhlangano). Awahlukani; i-valve eguquguqukayo kakhulu i-ai-valve yebhola lenyunyana yeqiniso, ehlanganisa zombili izici.
Leli elinye lamaphuzu avamile okudideka engiwabonayo, futhi kuwumehluko obalulekile kunoma yimuphi uchwepheshe. Ngivame ukuxoxa ngalokhu nozakwethu u-Budi e-Indonesia, ngoba amakhasimende akhe adinga izixazululo ezingezona nje ezisebenzayo kodwa futhi eziphumelelayo ukuzinakekela ngokuhamba kwesikhathi. Iqiniso liwukuthi, la magama achaza izinto ezimbili ezihlukene: eyodwa iyakutshelaKanjanii-valve iyasebenza, kanti enye iyakutshelaukuthi ixhuma kanjaniepayipini. Ukuqonda lo mehluko kuyisihluthulelo sokuklama uhlelo oluhlakaniphile, olusebenzisekayo.
Uyini umehluko phakathi kwe-valve yebhola kanye ne-valve yebhola lenyunyana?
Ufake i-valve yebhola ejwayelekile, uyinamathisele unomphela emugqeni. Ngemva konyaka, uphawu luyehluleka, futhi uyabona ukuthi okuwukuphela kwendlela ongakhetha ngayo ukusika yonke i-valve bese uqala kabusha.
I-valve yebhola ejwayelekile iyiyunithi eyodwa, efakwe unomphela. I-valve yebhola ye-union yeqiniso inamantongomane axhumanisa akuvumela ukuthi ukhiphe umzimba we-valve emaphakathi ngaphandle kokusika ipayipi, okwenza ukugcinwa noma ukushintshwa kube lula.
Lona umehluko obaluleke kakhulu wokuhlela isikhathi eside. Cabanga ngakho ngokwegama elithi “unomphela” uma liqhathaniswa nelithi “okusebenzisekayo.” Ivalvu yebhola elijwayelekile, elihlangene lishiselwa nge-solvent ngqo epayipini. Uma isingenile, isingene kahle. Lokhu kuhle emigqeni elula, engabalulekile. Ai-valve yebhola lenyunyana yeqinisoNokho, iklanyelwe ikusasa. U-solvent-weld iziqephu ezimbili ezihlukene ezihlukene epayipini, futhi umzimba we-valve oyinhloko uhlala phakathi kwazo. Iphethwe ngamantongomane amabili amakhulu enyunyana. Uma kwenzeka udinga ukufaka izigxivizo zevalvu noma umzimba wonke, umane ukhulule amantongomane bese uwakhipha. Kungakho thina kwa-Pntek silwela umklamo wangempela wezinyunyana; kuguqula ukulungisa okukhulu kube umsebenzi olula wemizuzu emi-5.
I-Standard vs. True Union Ball Valve
| Isici | Ivalvu Yebhola Ejwayelekile (Ehlangene). | I-True Union Ball Valve |
|---|---|---|
| Ukufakwa | Permanent (i-solvent-welded) | Kuyasebenziseka (amantongomane e-union) |
| Isondlo | Idinga ukusika ipayipi | Umzimba ukhishwa ukuze ulungiswe kalula |
| Izindleko Zokuqala | Phansi | Phezulu |
| Inani Lesikhathi Eside | Okuphansi (ukulungisa kubiza) | Okuphakeme (konga isikhathi nomsebenzi) |
Iyini i-valve yenyunyana?
Ubona igama elithi “valve yenyunyana” bese ucabanga ukuthi yisigaba esihluke ngokuphelele, njengevalvu yesango noma ivalvu yokuhlola. Lokhu kungabaza kungakugcina ekukhetheni inketho esebenzayo kakhulu.
I-valve yenyunyana ayilona uhlobo lomshini, kodwa uhlobo lokuxhuma. Yinoma iyiphi i-valve esebenzisa ukufakwa kwenyunyana (amantongomane anentambo) ukuxhuma umzimba wevalvu emaphethelweni epayipi, okuvumela ukususwa kalula.
"Inyunyana" ngokwayo iyingxenye yobunjiniyela obuhle kakhulu. Iqukethe izingxenye ezintathu eziyinhloko: izingcezu ezimbili ezingemuva ezixhumeka epayipini (kungaba nge-solvent weld noma imicu), kanye nenadi elinentambo eliwadonsa ndawonye ukuze enze uphawu. A “i-valve yenhlangano” imane yakha lesi sici ekwakhiweni kwevalvu. Ngakho, ungaba nevalvu yebhola lenyunyana yangempela, ivalve yokuhlola inyunyana yangempela, noma ivalve ye-diaphragm ye-union yangempela. Injongo ihlala ifana:ukusebenza kahle. Ikuvumela ukuthi uhlukanise futhi ususe ucezu lwemishini ngaphandle kokucindezela lonke uhlelo noma, okubaluleke kakhulu, ngaphandle kokusika ipayipi lakho. Le ndlela yokulinganisa iyisisekelo somklamo wesimanje, osebenza kahle wamapayipi kanye nengxenye eyinhloko yefilosofi ethi "win-win" engibelana ngayo nozakwethu abafana no-Budi. Igcina amakhasimende akhe isikhathi nemali empilweni yohlelo.
Yiziphi izinhlobo ezintathu zama-valve?
Ubusebenzisa ama-valve ebhola kuyo yonke into, kodwa uhlelo lokusebenza olulodwa ludinga ukulawula ukugeleza okunembayo. Uzama ukuvala kancane i-valve yebhola, kodwa kunzima ukuyilawula futhi uzwa umsindo ongajwayelekile.
Izinhlobo ezintathu eziyinhloko ezisebenzayo zamavalvu yi-Shut-Off (On/Off), Throttling (Regulating), kanye Non-Return (Backflow Prevention). Uhlobo ngalunye lwenzelwe umsebenzi ohluke ngokuphelele, futhi ukusebenzisa ongalungile kungalimaza uhlelo lwakho.
Ukwazi izigaba eziyisisekelo kubalulekile ekukhetheni ithuluzi elifanele lomsebenzi. Ukusebenzisa i-valve engalungile kuyiphutha elivame kakhulu. I-valve yebhola ingu-ai-valve yokuvala; yakhelwe ukuthi ivuleke ngokugcwele noma ivalwe ngokugcwele. Ukuyisebenzisela ukugeleza kwe-throttle kungabangela isiyaluyalu esicekela phansi ibhola nezihlalo, kubangele ukuthi lehluleke.
Izigaba Zevalvu Zichaziwe
| Uhlobo Lwevalvu | Umsebenzi Oyinhloko | Izibonelo Ezivamile | Ikesi elingcono kakhulu lokusebenzisa |
|---|---|---|---|
| Vala (Vula/Vala) | Ukumisa ngokuphelele noma ukuvumela ukugeleza. | I-Ball Valve, i-Gate Valve, i-Butterfly Valve | Ukuhlukanisa izingxenye noma okokusebenza. |
| I-Throttling (Ukulawula) | Ukulawula isivinini noma ingcindezi yokugeleza. | I-Globe Valve, I-Valve Yenaliti | Ukusetha izinga lokugeleza elinembile. |
| Okungabuyi (Backflow) | Ukuvumela ukugeleza ohlangothini olulodwa kuphela. | Hlola i-Valve, i-Foot Valve | Ukuvikela iphampu ekugelezeni emuva. |
Yiziphi izinhlobo ezi-4 zamavalvu ebhola?
Uyazi ngama-valve eqiniso, kodwa ubona ezinye izinketho njengokuthi "compact" noma "isiqephu esisodwa." Awunaso isiqiniseko sokuthi yikuphi okungcono kakhulu ezinhlelweni zokusebenza ezahlukene, futhi kungenzeka ukuthi ukhokha ngokweqile izici ongazidingi.
Izinhlobo ezine eziyinhloko zamavalvu ebhola zihlukaniswa ngokwakhiwa komzimba: Ucezu Olulodwa (oluvaliwe), Ucezu Olubili (umzimba onentambo), Ucezu Oluthathu (njengenyunyana yeqiniso), kanye neCompact (umklamo olula, ukonga, ngokuvamile ucezu olulodwa).
Nakuba umshini wangaphakathi ufana (ibhola elijikelezayo), indlela umzimba owakhiwe ngayo ibeka izindleko zawo kanye nokusebenza kwawo. Emhlabeni we-PVC, sigxile kakhulu ekwakhiweni kocezu olulodwa/okuhlangene kanye nemiklamo emithathu/yenyunyana yeqiniso.
- Ucezu olulodwa /I-Compact Ball Valve:Umzimba we-valve uyiyunithi eyodwa, evaliwe. Lona umklamo owonga kakhulu. Ayisindi, ilula, futhi ilungele izinhlelo zokusebenza lapho ukunakekelwa kungeyona into ekhathazayo futhi izindleko ziwumshayeli oyinhloko.
- I-valve yebhola eneziqephu ezimbili:Umzimba wenziwe ngezingcezu ezimbili ezihlangana ndawonye, zicuphe ibhola futhi zivale ngaphakathi. Lokhu kuvumela ukulungiswa okuthile kodwa ngokuvamile kudinga ukuyisusa kulayini. Kuvame kakhulu kumavalvu ensimbi.
- Izingxenye ezintathu (I-True Union) I-Ball Valve:Lona umklamo we-premium. Iqukethe izixhumi ezimbili zokugcina (iziqephu ezingemuva) kanye nomzimba ophakathi. Lokhu kuvumela umzimba omkhulu ukuba ususwe ukuze ulungiswe noma ushintshwe ngaphandle kokuphazamisa ipayipi. Lokhu ukukhetha okuthembeke kakhulu futhi okungabizi kakhulu kwezinhlelo zokusebenza ezibucayi esikhathini eside.
Kwa-Pntek, sigxile ekunikezeni i-compact engcono kakhulu futhiama-valve eqiniso, ukunikeza ozakwethu abanjengoBudi izinketho ezifanele zanoma yisiphi isidingo samakhasimende.
Isiphetho
I-valve yebhola iwumshini; inyunyana iwukuxhumana. I-valve yebhola lenyunyana yangempela iyawahlanganisa, inikeze ukulawula okuphakeme nokugcinwa kalula kwanoma iyiphi isistimu yamapayipi ochwepheshe.
