Ubona "inyunyana yangempela" kanye "nenyunyana ephindwe kabili" evela kubaphakeli abahlukene. Lokhu kudala ukungabaza. Ingabe u-oda i-valve efanele, esebenza ngokugcwele amakhasimende akho ayilindele njalo?

Akukho mehluko. Igama elithi “umanyano weqiniso” kanye nelithi “umanyano ophindwe kabili” amagama amabili omklamo ofanayo: ivalvu enezingcezu ezintathu enamantongomane amabili e-union. Lo mklamo ukuvumela ukuthi ususe umzimba wevalvu ephakathi ngokuphelele ngaphandle kokunquma ipayipi.

Ngivame ukuba nale ngxoxo nomlingani wami uBudi e-Indonesia. Amagama angadida ngoba izifunda ezahlukene noma abakhiqizi bangase bakhethe igama elilodwa kunelinye. Kodwa kumphathi wokuthenga onjengaye, ukungaguquguquki kubalulekile ukuze kugwenywe amaphutha. Ukuqonda ukuthi la magama asho i-valve efanayo ephakeme kwenza kube lula inqubo yoku-oda. Kuqinisekisa ukuthi amakhasimende akhe ahlala ethola umkhiqizo ofaneleka kahle, osezingeni eliphezulu abawudingayo kumaphrojekthi abo.

Kusho ukuthini ukuhlangana kweqiniso?

Uzwa igama elithi “ubumbano lweqiniso” futhi lizwakala njengobuchwepheshe noma liyinkimbinkimbi. Ungase uligweme, ucabange ukuthi liyinto ekhethekile esikhundleni se-valve esebenzayo njengoba linjalo ngempela.

“Ubumbano lweqiniso” kusho ukuthi i-valve inikezaiqinisoukusebenziseka. Inezixhumanisi zokuxhumanisa kuzo zombili izinhlangothi, okuvumela umzimba oyinhloko ukuthi ususwe ngokuphelele epayipini ukuze kulungiswe noma kushintshwe ngaphandle kokucindezela ipayipi.

Igama eliyinhloko lapha lithi “iqiniso.” Lisho ikhambi eliphelele nelifanele lokulungisa.i-valve yomanyano yangempelakuhlale kuyi-ukuhlanganiswa kwezingcezu ezintathu: iziphetho ezimbili zokuxhumanisa (ezibizwa ngokuthi izingcezu zangemuva) kanye nomzimba wevalvu ephakathi. Izingcezu zangemuva zinamathiselwe epayipini. Umzimba ophakathi, obamba indlela yebhola kanye nezivalo, ubanjwa phakathi kwawo ngamantongomane amabili amakhulu. Uma ukhulula la mantongomane, umzimba ungaphakanyiswa uqonde ngaphandle. Lokhu kuhlukile kuvalvu "yomunye union" ekhipha ingxenye kuphela futhi engabangela ezinye izinkinga. Umklamo "weqiniso" yilokho esikwakhayo kwa-Pntek ngoba ubonisa ifilosofi yethu: ukudala ukubambisana kwesikhathi eside, okuwina wonke umuntu ngokuhlinzeka ngemikhiqizo esindisa isikhathi nemali kumakhasimende ethu kuyo yonke impilo yesistimu. Umklamo ochwepheshile nothembekile kakhulu otholakalayo.

Kusho ukuthini ukuhlangana kabili?

Uyakuqonda “ubumbano lweqiniso,” kodwa bese ubona umkhiqizo obhalwe “njengobumbano oluphindwe kabili.” Uyazibuza ukuthi ngabe lokhu kuyinguqulo entsha, engcono, noma okunye ngokuphelele, okubangela ukungabaza.

Igama elithi “Double union” limane nje lichaza into efanayo nevalvu yangempela yomanyano. Lisho ukuthi ivalvu inoxhumano lomanyano kuezimbili(noma kabili) izinhlangothi, okwenza kube lula ukususa ngokuphelele.

Leli yiphuzu elivame kakhulu lokudideka, kodwa impendulo ilula kakhulu. Cabanga ngokuthi “ukuhlangana okuphindwe kabili” njengencazelo engokoqobo kanye nokuthi “ukuhlangana kweqiniso” njengegama lobuchwepheshe lenzuzo elikunikezayo. Asetshenziswa ukusho into efanayo. Kufana nokubiza imoto ngokuthi “imoto” noma “imoto.” Amagama ahlukene, into efanayo. Ngakho-ke, ukuze kucace ngokuphelele:

Ubumbano Lweqiniso = Inyunyana Ephindwe Kabili

Kungani amagama womabili ekhona? Ngokuvamile kuncike emikhubeni yesifunda noma ekukhetheni komkhiqizi ukumaketha. Abanye bakhetha "ukuhlangana okuphindwe kabili" ngoba kuchaza ngokoqobo la magama amabili. Abanye, njengathi kwa-Pntek, bavame ukusebenzisa "ukuhlangana kweqiniso" ngoba kugcizelela inzuzo yokuthiukusebenziseka kwangempela. Kungakhathaliseki ukuthi ubona liphi igama, uma ivalvu inomzimba onezingcezu ezintathu onamantongomane amabili amakhulu nhlangothi zombili, ubheka umklamo ofanayo ongcono kakhulu. Yilokho uBudi akudingayo ukuze anikeze izixazululo ezinokwethenjelwa kumakhasimende akhe ahlukahlukene e-Indonesia.

Yiluphi uhlobo lwe-ball valve olungcono kakhulu?

Ufuna ukugcina nokuthengisa ivalvu “engcono kakhulu” yebhola. Kodwa ukunikeza inketho ebiza kakhulu yomsebenzi olula kungalahlekelwa ukuthengiswa, kuyilapho ivalvu eshibhile emgqeni obalulekile ingahluleka.

Ivalvu yebhola "engcono kakhulu" yileyo efanelana kahle nezidingo zohlelo lokusebenza. Ukuze isetshenziswe kahle futhi ibe nenani lesikhathi eside, ivalvu yokuhlanganisa yangempela ingcono kakhulu. Ngezinhlelo zokusebenza ezilula nezingabizi kakhulu, ivalvu encane ivame ukwanele.

“Okuhle kakhulu” kuncike ezintweni eziza kuqala emsebenzini. Amavalvu amabili ebhola le-PVC avame kakhulu yilawaincane (ingxenye eyodwa)kanye nenyunyana yangempela (izingxenye ezintathu). Isazi sokuthenga njengoBudi sidinga ukuqonda ukuguquguquka ukuze siqondise amakhasimende aso ngendlela efanele.

Uyini umehluko phakathi kwamavalvu ebhola le-single union namavalvu ebhola le-double union?

Ubona ivalvu “eyi-single union” eshibhile bese ucabanga ukuthi kuyisivumelwano esihle. Kodwa lokhu kungaholela ezinkingeni ezinkulu kumfaki ngesikhathi somsebenzi wokuqala wokulungisa.

Ivalvu eyodwa ye-union ine-union nut eyodwa, ngakho-ke uhlangothi olulodwa kuphela olungasuswa. I-union ephindwe kabili inama-nuts amabili, okwenza umzimba wonke we-valve ususwe ngaphandle kokugoba noma ukucindezela ipayipi elixhunyiwe.

Umehluko ekulungiseni kahle mkhulu kakhulu, yingakho ochwepheshe cishe njalo bekhetha umklamo we-double union. Ake sicabange ngenqubo yokulungisa yangempela.

Inkinga Ngobunye Bomuntu Oyedwa

Ukususa i-ivalvu yomanyano olulodwa, uqala ngokukhumula i-nut eyodwa. Olunye uhlangothi lwe-valve lusanamathele unomphela epayipini. Manje, kufanele udonse amapayipi bese uwagoba ukuze umzimba we-valve uphume. Lokhu kubeka ingcindezi enkulu emajoyintini nasezintweni eziseduze. Kungabangela kalula ukuvuza okusha kwenye indawo ohlelweni. Kuguqula ukulungiswa okulula kube umsebenzi oyingozi. Kuyidizayini exazulula ingxenye yenkinga kuphela.

Inzuzo Yokuhlanganiswa Okubili

Ngevalvu yokuhlanganisa kabili (i-true union), inqubo ilula futhi iphephile. Ukhulula amantongomane womabili. Umzimba ophakathi, oqukethe zonke izingxenye ezisebenzayo, uphakamisa uqonde phezulu nangaphandle. Akukho ukucindezeleka kumapayipi noma kuma-fitting. Ungashintsha izivalo noma umzimba wonke ngemizuzu, uwubuyisele ngaphakathi, bese uqinisa amantongomane. Lesi yisisombululo sobungcweti kuphela sokuxhuma okulungisekayo.

Isiphetho

I-“True union” kanye ne-“double union” zichaza umklamo ofanayo we-valve osezingeni eliphezulu. Ukuze kube lula ukusebenza kanye nemiphumela yobungcweti, uxhumano lwe-double union luhlala luyisinqumo esifanele nesingcono kakhulu.
