Ubona "umanyano lokwenyani" kunye "nomanyano oluphindwe kabini" kubathengisi abahlukeneyo. Oku kudala amathandabuzo. Ngaba uodola ivalvu efanelekileyo, esebenza ngokupheleleyo elindelekileyo kubathengi bakho ngalo lonke ixesha?

Akukho mahluko. Igama elithi “umanyano lokwenyani” kunye nelithi “umanyano oluphindwe kabini” ngamagama amabini oyilo olufanayo: ivalvu enamacandelo amathathu eneentonga ezimbini zomanyano. Olu yilo lukuvumela ukuba ususe umzimba wevalvu ephakathi ngokupheleleyo ngaphandle kokunqumla umbhobho.

Ndihlala ndithetha ngale ncoko neqabane lam uBudi e-Indonesia. Eli gama linokudida kuba iindawo ezahlukeneyo okanye abavelisi banokukhetha igama elinye kunelinye. Kodwa kumphathi wokuthenga onjengaye, ukuhambelana kubalulekile ukuze kuthintelwe iimpazamo. Ukuqonda ukuba la magama athetha ivalvu efanayo egqwesileyo kwenza kube lula inkqubo yoku-odola. Iqinisekisa ukuba abathengi bakhe bahlala befumana imveliso efanelekileyo nesemgangathweni abayifunayo kwiiprojekthi zabo.

Kuthetha ukuthini umanyano lokwenyani?

Uva igama elithi “umanyano lokwenyani” kwaye livakala ngathi lolobuchwephesha okanye liyinkimbinkimbi. Usenokuliphepha, ucinga ukuba yinto ekhethekileyo endaweni yevalvu yokusebenza njengoko injalo ngokwenene.

“Umanyano lokwenyani” lithetha ukuba ivalvu inikayinyaniIsebenza kakuhle. Inemiqhagamshelo yomanyano kuzo zombini iziphelo, ivumela umzimba oyintloko ukuba ususwe ngokupheleleyo kumbhobho ukuze ulungiswe okanye utshintshwe ngaphandle koxinzelelo kumbhobho.

Igama eliphambili apha lithi “inyaniso.” Lithetha isisombululo esipheleleyo nesifanelekileyo sokugcinwa.ivalvu yomanyano lokwenyaniihlala iindibano enamacandelo amathathu: iziphelo ezimbini zokudibanisa (ezibizwa ngokuba zii-tailpieces) kunye nomzimba wevalvu ephakathi. Ii-tailpieces zincamatheliswe kumbhobho. Umzimba ophakathi, obamba indlela yebhola kunye nezitywino, ubanjwa phakathi kwazo ngamantongomane amabini amakhulu. Xa ukhulula la mantongomane, umzimba ungaphakanyiswa ngqo. Oku kwahlukile kwivalvu "yomanyano olunye" ekhupha inxalenye kuphela kwaye inokubangela ezinye iingxaki. Uyilo "lokwenyani" yinto esiyakhayo kwaPntek kuba ibonisa ifilosofi yethu: ukudala intsebenziswano yexesha elide, ephumelela kumacala omabini ngokubonelela ngeemveliso ezisindisa abathengi bethu ixesha nemali kulo lonke ubomi benkqubo. Luyilo lolona luchwephesha noluthembekileyo olufumanekayo.

Kuthetha ukuthini umanyano oluphindwe kabini?

Uyayiqonda "imanyano yokwenyani," kodwa emva koko ubona imveliso idweliswe njenge "manyano oluphindwe kabini." Uzibuza ukuba ngaba le yinguqulelo entsha, engcono, okanye yinto eyahlukileyo ngokupheleleyo, ebangela ukuthandabuza.

Igama elithi “Double union” lichaza into efanayo nevalvu yokwenyani yomanyano. Lithetha nje ukuba ivalvu inonxibelelwano lomanyanoMbini(okanye amacala amabini), nto leyo eyenza ukuba isuswe ngokupheleleyo.

Le yeyona ngongoma ixhaphakileyo yokudideka, kodwa impendulo ilula kakhulu. Cinga "ngomanyano oluphindwe kabini" njengenkcazo echanekileyo kunye "nomanyano lokwenyani" njengegama lobuchwephesha lenzuzo eliyibonelelayo. Zisetyenziswa ukuthetha into enye. Kufana nokubiza imoto ngokuthi "imoto" okanye "isithuthi." Amagama ahlukeneyo, into efanayo. Ngoko ke, ukuze kucace mhlophe:

Umanyano Lwenene = Umanyano oluphindwe kabini

Kutheni la magama omabini ekho? Idla ngokuxhomekeke kwimikhwa yengingqi okanye ukhetho lomenzi wentengiso. Abanye bakhetha "umanyano oluphindwe kabini" kuba luchaza ngokwasemzimbeni la magama mabini. Abanye, njengathi kwaPntek, badla ngokusebenzisa "umanyano lokwenyani" kuba lugxininisa inzuzo yokubaukusebenziseka kweneneNokuba ubona liphi igama, ukuba ivalvu inomzimba oneziqwenga ezintathu kunye neenati ezimbini ezinkulu kumacala omabini, ujonge uyilo olufanayo olugqwesileyo. Yinto uBudi ayidingayo ukuze anike izisombululo ezithembekileyo kubathengi bakhe abahlukeneyo eIndonesia.

Yeyiphi ivalvu yebhola engcono kakhulu?

Ufuna ukugcina nokuthengisa ivalvu yebhola "eyona ilungileyo". Kodwa ukunika ukhetho olubiza kakhulu lomsebenzi olula kunokulahlekelwa yintengiso, ngelixa ivalvu engabizi kakhulu kumgca obalulekileyo inokungaphumeleli.

Ivalvu yebhola "eyona ilungileyo" yileyo ihambelana ngokuchanekileyo neemfuno zesicelo. Ukuze isebenze kakuhle kwaye ibe nexabiso elide, ivalvu yomanyano yokwenyani yeyona ilungileyo. Kwizicelo ezilula nezingabizi kakhulu, ivalvu encinci idla ngokwanela.

“Olona lubalaseleyo” luxhomekeke kwizinto eziza kuqala kumsebenzi. Iivalvu ezimbini zebhola zePVC ezixhaphakileyo zeziincinci (inxalenye enye)kunye nomanyano lokwenyani (oluneziqwenga ezintathu). Ingcali yokuthenga efana noBudi kufuneka iqonde urhwebo ukuze ikhokele abathengi bayo ngokufanelekileyo.

Yintoni umahluko phakathi kwe-single union kunye ne-double union ball valves?

Ubona ivalvu "ye-single union" engabizi kakhulu kwaye ucinga ukuba yimvumelwano elungileyo. Kodwa oku kunokubangela iintloko ezibuhlungu kumfaki ngexesha lomsebenzi wokuqala wokulungisa.

Ivalvu enye ye-union ine-union nut enye, ngoko ke icala elinye kuphela elisuswayo. I-union ephindwe kabini inee-nuts ezimbini, nto leyo eyenza umzimba wonke wevalvu ususwe ngaphandle kokugoba okanye ukucinezela umbhobho odibeneyo.

Umahluko kwindlela esebenza ngayo mkhulu kakhulu, yiyo loo nto iingcali zihlala zikhetha uyilo lwe-double union. Makhe sicinge ngenkqubo yokulungisa yokwenyani.

Ingxaki Ngomanyano Olungatshatanga

Ukususaivalvu yomanyano olunye, uqala ngokuyikhulula inati enye. Elinye icala levalvu lisancamathiselwe kumbhobho ngokusisigxina. Ngoku, kufuneka utsale imibhobho ngokwasemzimbeni uze uyigobe ukuze umzimba wevalvu uphume. Oku kubeka uxinzelelo olukhulu kwiindawo ezikufutshane kunye nezixhobo. Kunokubangela ukuvuza okutsha kwenye indawo kwinkqubo. Kuguqula ukulungiswa okulula kube ngumsebenzi onobungozi. Luyilo olusombulula isiqingatha sengxaki kuphela.

Inzuzo yoManyano oluBini

Ngevalvu yomanyano oluphindwe kabini (i-true union), le nkqubo ilula kwaye ikhuselekile. Ukhulula zombini iinati. Umzimba ophakathi, oqulethe zonke iindawo ezisebenzayo, uphakamisa ngqo phezulu nangaphandle. Akukho xinzelelo kwimibhobho okanye kwizixhobo. Ungazitshintsha izitywini okanye umzimba wonke ngemizuzu embalwa, uzibuyisele ngaphakathi, kwaye uziqinise iinati. Le yeyona sisombululo sobuchwephesha sokudibanisa okulungisekayo.

Isiphelo

I-“True union” kunye ne-“double union” zichaza uyilo olufanayo lwevalvu oluphezulu. Ukuze kubekho ukusebenza kakuhle kunye neziphumo zobungcali, uqhagamshelo lwe-double union luhlala lulungile kwaye lukhetho olufanelekileyo.
