Ubona “inyunyana yeqiniso” kanye “nenyunyana ephindwe kabili” kubahlinzeki abahlukene. Lokhu kudala ukungabaza. Ingabe uyala i-valve efanele, esebenza ngokugcwele elindelwe amakhasimende akho ngaso sonke isikhathi?

Awukho umehluko. “Inyunyana yeqiniso” kanye “nenyunyana ekabili” amagama amabili omklamo ofanayo: ivalvu eneziqephu ezintathu ezinamantongomane amabili enyunyana. Lo mklamo ikuvumela ukuthi ususe umzimba we-valve emaphakathi ngokuphelele ngaphandle kokusika ipayipi.

Ngiba nale ngxoxo kaningi nozakwethu u-Budi e-Indonesia. Amagama angadida ngoba izifunda ezihlukene noma abakhiqizi bangase bakhethe igama elilodwa kunelinye. Kodwa kumphathi wokuthenga njengaye, ukungaguquguquki kuyisihluthulelo sokugwema amaphutha. Ukuqonda ukuthi la magama asho ukuthi ivalvu efanayo ephezulu yenza inqubo yoku-oda ibe lula. Iqinisekisa ukuthi amaklayenti akhe ahlala ethola umkhiqizo osebenzisekayo, osezingeni eliphezulu awudingayo kumaphrojekthi awo.

Kusho ukuthini ukuhlangana kweqiniso?

Uzwa igama elithi "inyunyana yeqiniso" futhi lizwakala liyinkimbinkimbi noma liyinkimbinkimbi. Ungase uyigweme, ucabange ukuthi yinto ekhethekile esikhundleni se-valve ye-workhorse eyikho ngempela.

"Inyunyana yeqiniso" isho i-valve enikezwayoiqinisoukusebenza kahle. Inokuxhumana kwezinyunyana kuzo zombili iziphetho, okuvumela umzimba omkhulu ukuthi ususwe ngokuphelele epayipini ukuze lilungiswe noma lishintshwe ngaphandle kokugcizelela ipayipi.

Igama eliyinhloko lapha lithi “iqiniso.” Isho isixazululo esiphelele nesilungile sokunakekela. Ai-valve ye-union yeqinisonjalo aumhlangano weziqephu ezintathu: iziphetho ezimbili zokuxhuma (ezibizwa ngokuthi ama-tailpiece) kanye nomzimba we-valve ophakathi. Iziqephu zangemuva zinamathiselwe epayipini. Umzimba ophakathi, ophethe indlela yebhola kanye nezimpawu, ubanjwe phakathi kwawo ngamantongomane amabili amakhulu. Uma uqaqa lamantongomane, umzimba ungaphakanyiswa uphumele ngaphandle. Lokhu kuhlukile ku-valve “yenyunyana eyodwa” enikeza kuphela ukususwa ingxenye futhi engabangela ezinye izinkinga. Umklamo “weqiniso” yilokho esiwakhayo thina kwa-Pntek ngoba ubonisa ifilosofi yethu: dala ukusebenzisana kwesikhathi eside, okuphumelelayo ngokunikeza imikhiqizo ezongela amakhasimende ethu isikhathi nemali kuyo yonke impilo yesistimu. Iwumklamo osezingeni eliphezulu nothembekile otholakalayo.

Kusho ukuthini ukubumbana kabili?

Uyaqonda “inyunyana yeqiniso,” kodwa bese ubona umkhiqizo usohlwini “njengenyunyana ekabili.” Uyazibuza ukuthi ingabe lena inguqulo entsha, engcono, noma enye into ngokuphelele, ebangela ukungabaza.

“Inyunyana ekabili” yigama elichaza kakhudlwana lento efanayo nevalvu yenyunyana yangempela. Kusho ukuthi i-valve inokuxhumana kwenyunyanaezimbili(noma kabili) izinhlangothi, okwenza isuse ngokuphelele.

Leli yiphuzu elivame kakhulu lokudideka, kodwa impendulo ilula kakhulu. Cabanga ngokuthi “inyunyana ekabili” njengencazelo engokoqobo kanye “nenyunyana yeqiniso” njengegama lobuchwepheshe lenzuzo eyinikezayo. Asetshenziswa ukusho into efanayo. Kufana nokubiza imoto ngokuthi “imoto” noma “ngemoto.” Amagama ahlukene, into efanayo. Ngakho, ukuze kucace ngokuphelele:

Inyunyana Yeqiniso = I-Double Union

Kungani ekhona womabili amagama? Ivamise ukufika emikhubeni yesifunda noma ekukhetheni ukumaketha komkhiqizi. Abanye bakhetha “ukuhlangana kabili” ngoba kuchaza amantongomane amabili. Abanye, njengathi ePntek, bavame ukusebenzisa “inyunyana yeqiniso” ngoba igcizelela inzuzoukusebenza kweqiniso. Kungakhathaliseki ukuthi yiliphi igama olibonayo, uma i-valve inomzimba oneziqephu ezintathu namantongomane amabili amakhulu nhlangothi zombili, ubheka umklamo ofanayo ophezulu. Yilokho uBudi akudingayo ukuze anikeze izixazululo ezinokwethenjelwa kumakhasimende akhe ahlukahlukene e-Indonesia.

Iluphi uhlobo olungcono kakhulu lwe-valve yebhola?

Ufuna ukubeka futhi udayise i-valve yebhola “engcono kakhulu”. Kodwa ukunikeza inketho ebiza kakhulu yomsebenzi olula kungalahlekelwa ukudayiswa, kuyilapho i-valve eshibhile emgqeni obalulekile ingahluleka.

Ivalve yebhola “engcono kakhulu” yileyo ehambisana kahle nezidingo zohlelo lokusebenza. Ukuze uthole usizo kanye nenani lesikhathi eside, i-valve ye-union yangempela iyona engcono kakhulu. Ngezicelo ezilula, ezingabizi kakhulu, i-valve ehlangene ivame ukwanele.

“Okuhle kakhulu” kuncike ezintweni eziza kuqala emsebenzini. Ama-valve amabili ebhola e-PVC ajwayelekile kakhulukuhlangene (isiqephu esisodwa)kanye nobunye beqiniso (iziqephu ezintathu). Uchwepheshe wokuthenga ofana no-Budi udinga ukuqonda ukuhwebelana ukuze aqondise amakhasimende akhe ngendlela efanele.

Uyini umehluko phakathi kwe-single union kanye nama-valve amabhola e-double union?

Ubona ivalvu “yenyunyana eyodwa” eshibhile bese ucabanga ukuthi kuwukuvumelana okuhle. Kodwa lokhu kungaholela ekhanda elikhulu lomfaki ngesikhathi somsebenzi wokuqala wokulungisa.

Ivalvu yenyunyana eyodwa inenadi elilodwa lenyunyana, ngakho-ke uhlangothi olulodwa kuphela olukhiphekayo. I-double union inamantongomane amabili, okwenza wonke umzimba we-valve ukhiphe ngaphandle kokugoba noma ukucindezela ipayipi elixhunyiwe.

Umehluko ekusebenzeni mkhulu, yingakho ochwepheshe cishe njalo bekhetha umklamo wezinyunyana ezimbili. Ake sicabange ngenqubo yangempela yokulungisa.

Inkinga nge-Single Union

Ukususa ai-valve yenhlangano eyodwa,uqale ngokuqaqa inadi elilodwa. Olunye uhlangothi lwe-valve lusanamathele unomphela epayipini. Manje, kufanele udonse amapayipi ngokwawo bese uwagoba ukuze ukhiphe umzimba we-valve. Lokhu kubeka ingcindezi enkulu emalungeni nasezixhunyweni eziseduze. Ingabangela kalula ukuvuza okusha kwenye indawo ohlelweni. Ishintsha ukulungisa okulula kube ukusebenza okuyingozi. Kuwumklamo oxazulula ingxenye yenkinga kuphela.

Inzuzo ye-Double Union

Nge-valve yenyunyana ephindwe kabili (inyunyana yeqiniso), inqubo ilula futhi iphephile. Uqaqa amantongomane womabili. Umzimba ophakathi, oqukethe zonke izingxenye ezisebenzayo, uphakamisa uqonde phezulu nangaphandle. Kukhona ukucindezeleka okungu-zero kumapayipi noma okokufaka. Ungashintsha izimpawu noma umzimba wonke ngemizuzu, uwubuyisele phakathi, bese uqinisa amantongomane. Lesi ukuphela kwesixazululo sochwepheshe sokuxhumana okuseviswayo.

Isiphetho

“Inyunyana yeqiniso” kanye “nenyunyana ekabili” ichaza ukwakheka okufanayo kwamavalvu aphezulu. Ukuze uthole isevisi yangempela kanye nemiphumela yobungcweti, uxhumano lwenyunyana oluphindwe kabili luhlala luyisinqumo esilungile nesingcono kakhulu.
