Epayipini lepayipi lokufakwa kwamapayipi amaphampu kanye nokunye ukuklama noma ukuthenga sivame ukuhlangana ne-DN, amayintshi ", Φ namanye amayunithi, kunabangane abaningi (ikakhulukazi abaningi abasha embonini yezicathulo) kulokhu kudidekile, abakwazi ukuhlukanisa imodeli, namuhla thina izofingqa isifinyezo samayunithi amathathu okuhlaziya okuqondile kwesifunda.
1.DN
“DN” abangani abaningi ngephutha bacabanga ukuthi ububanzi bangaphakathi, ngempela i-DN kanye nobubanzi obungaphakathi bokusondelene, kodwa obuseduze kuphela, incazelo yalo yangempela ipayipi, ipayipi, izifakelo ezinobubanzi obuncane, ububanzi obuncane (Nominal Diameter), eyaziwa nangokuthi I-diameter emaphakathi engaphandle (I-Mean Outside Diameter), empeleni, icishe ibe yi-avareji ububanzi obungaphandle.
Kuvelu ye-DN yasekhaya ngokuyisisekelo ivame kakhulu, kodwa epayipini, ukufakwa kwamapayipi nama-valve kungamela ingxenye kuphela, kungani kuyingxenye yakho?Ngoba ohlelweni lwamapayipi asekhaya, kungaba nezinhlobo ezimbili zobubanzi bangaphandle epayipini elifanayo elimakwe nge-DN (Φ ububanzi obungaphandle bepayipi noma ipayipi, sizokuchaza kamuva), njenge-DN100, kukhona uchungechunge lwe-I kanye nochungechunge lwe-II (futhi iwusizo ukumaka uchungechunge oluthi A nochungechunge B), I series kanye no-A lwe-DN100 luyi-Φ114.3, kuyilapho uchungechunge lwe-II no-B lwe-DN100 luyi-Φ108.Uma ungacacisi ububanzi bangaphandle bepayipi Φ ngemva kwe-DN lapho wethula uhlelo nemininingwane, udinga ukucacisa ukuthi uchungechunge lwe-I (A series) noma II (B series) uma umaka nge-DN, ukuze kucacile ekuthengeni nasekuphenyeni, futhi ungakwazi ukwazi ukuthi hlobo luni lwepayipi noma ukufaka ububanzi obungaphandle obufunayo ngaphandle kokuxhumana nokuqinisekisa.
2. Amayintshi
I-Inch” iyiyunithi yombuso, esetshenziswa kakhulu eMelika naseYurophu, nayo iyiyunithi, yebo, inepayipi lePipe neTube, namuhla sizonaba ngesigaba sePipe yamapayipi nokufakwa, kamuva sizokwethula, Ipayipi lepayipi kanye neThubhu. iphayiphi umehluko othize.
Epayipini lepayipi, i-intshi ayifani neyunithi ye-DN ukuhlukanisa ububanzi obungaphandle bezinhlobo ezimbili zamapayipi, iyiyunithi ecacile, njengokuthi 4″ okushiwo ngokucacile ukuthi ububanzi obungaphandle obungu-114.3, futhi u-10″ ngu-Φ273, inqobo nje uma ipayipi noma ukufakwa okuchazwe ngama-intshi kungaziwa ngokucacile ngaphandle kokuqinisekiswa kwepayipi elidingekayo usayizi we-diameter yangaphandle.
3. Ububanzi Φ
Uphawu lobubanzi ngu-“Φ”, okungelohlamvu lwesiGreki, olubizwa ngokuthi “fai”, futhi linobudlelwano obuseduze kakhulu nalezi ezimbili ezidlule, ngoba lungangena esikhundleni salezi zingxenye ezimbili ezingenhla, kanye nepayipi noma ipayipi lisebenzisa u-Φ iyona ecace kakhulu, futhi iyona eqondile kakhulu ngaphandle kokuguqulwa, njenge-Φ219, Φ508, Φ1020, njll. Le ndlela yokuhlonza futhi ibanzi kakhulu.
