Ntchito zothirira ndi ntchito yotenga nthawi yambiri yomwe ingakhale yokwera mtengo mwachangu. Njira yabwino yosungira ndalama pa ntchito yothirira ndikugwiritsa ntchito chitoliro cha PVC pa chitoliro cha nthambi, kapena chitoliro pakati pa valavu pa chitoliro chachikulu cha madzi ndi chothirira madzi. Ngakhale chitoliro cha PVC chimagwira ntchito bwino ngati chinthu chopingasa, mtundu wa chitoliro cha PVC chomwe chikufunika umasiyana malinga ndi ntchito. Posankha mapaipi oti mugwiritse ntchito pantchito yanu, ndikofunikira kuonetsetsa kuti mukuganizira zinthu zakunja monga kuthamanga kwa madzi ndi kuwala kwa dzuwa. Kusankha mtundu wolakwika kungayambitse kukonza kowonjezera komanso kosafunikira. Nkhani ya blog ya sabata ino ikufotokoza mitundu yodziwika bwino ya mapaipi othirira a PVC. Konzekerani kusunga nthawi, madzi ndi ndalama!

Ndondomeko 40 ndi Ndondomeko 80 ya Chitoliro cha PVC Chitoliro cha PVC
Posankha mapaipi othirira a PVC, mapaipi onse a Schedule 40 ndi Schedule 80 ndi mitundu yodziwika bwino ya mapaipi a PVC othirira. Amalimbana ndi kupsinjika kofanana, kotero ngati mungasankhe Schedule 40, simudzadandaula za kusokonezeka pafupipafupi. Chitoliro cha Schedule 80 chili ndi makoma okhuthala ndipo motero chimakhala cholimba bwino, kotero mungafune kugwiritsa ntchito chitoliro cha Schedule 80 ngati mukumanga makina apamwamba.

Kaya mungasankhe mtundu wanji wa chitoliro cha PVC, ndikofunikira kuti chitolirocho chisawonekere ku dzuwa pang'ono momwe mungathere. Ngakhale mitundu ina ya PVC imalimbana ndi dzuwa kuposa ina, chitoliro chilichonse cha PVC chomwe chimawonedwa ndi dzuwa kwa nthawi yayitali chingathe kusweka mwachangu. Pali njira zingapo zodzitetezera ku dzuwa pamakina anu othirira. Utoto wa latex wakunja 3-4 umapereka chitetezo chokwanira ku dzuwa. Muthanso kugwiritsa ntchito chitoliro cha thovu. Makina apansi panthaka safuna chitetezo ku dzuwa. Pomaliza, kuthamanga kwa madzi si vuto lalikulu pankhani ya mapaipi a nthambi. Kusintha kwa kuthamanga kwa mphamvu zambiri mumakina othirira kumachitika pamzere waukulu. Pambuyo pake, mudzafunika chitoliro cha PVC chokha chokhala ndi PSI yofanana ndi kuthamanga kwa makina.

kuyala mapaipi

Ngati mwasankha njira yolowera pansi pa nthaka, onetsetsani kuti mwaika mapaipiwo pansi pa kuya kwa mainchesi osachepera 10.Mapaipi a PVCNdi zofooka ndipo zimatha kusweka kapena kusweka mosavuta ndi fosholo. Komanso, chitoliro cha PVC chosakwiriridwa chimakhala chozama mokwanira kuti nthawi yozizira ikwere pamwamba pa nthaka. Ndibwinonso kuyika chitoliro cha thovu pamakina onse apamwamba komanso pansi pa nthaka. Chitolirochi chimateteza mapaipi omwe ali pamwamba pa nthaka ku dzuwa ndipo chimateteza ku kuzizira m'nyengo yozizira.

Ngati mwasankha kugwiritsa ntchito chitoliro cha PVC pa nthambi yanu yothirira, onetsetsani kuti mwagwiritsa ntchito chitoliro chokhala ndi makulidwe osachepera 3/4″. Nthambi ya 1/2″ ikhoza kutsekeka mosavuta. Ngati mwasankha kugwiritsa ntchito zolumikizira, mitundu yodziwika bwino ya zolumikizira za PVC idzagwira ntchito bwino. Zolumikizira za socket zokhala ndi primer/simenti zimatha kugwira bwino, komanso zolumikizira za ulusi (chitsulo ndi PVC). Muthanso kugwiritsa ntchito zolumikizira zokakamiza, zomwe zimatseka pamalo pake pogwiritsa ntchito zotsekera ndi mano osinthasintha. Ngati mugwiritsa ntchito zolumikizira zokakamiza, onetsetsani kuti mwasankha cholumikizira chokhala ndi chosindikizira chapamwamba kwambiri.

Chitoliro cha Polyethylene ndi Chitoliro cha PEX PEX
Chitoliro cha polyethylene ndi chitoliro cha PEX ndi zipangizo zabwino kwambiri zogwiritsira ntchito nthambi zothirira. Zipangizozi zimagwira ntchito bwino kwambiri pansi pa nthaka; kusinthasintha kwake kumawapangitsa kukhala abwino kugwiritsa ntchito pafupi ndi dothi la miyala kapena miyala ikuluikulu. Chitoliro cha polyethylene ndi chitoliro cha PEX chimagwiranso ntchito bwino m'malo ozizira. Sizifunikira chotenthetsera china chilichonse kuti zisalowe m'malo ozizira. Mukasankha kugwiritsa ntchito chimodzi kapena china, kumbukirani kuti chitoliro cha PEX kwenikweni ndi mtundu wolimba pang'ono wa chitoliro cha polyethylene. Komabe, mtengo wokwera wa chitoliro cha PEX umapangitsa kuti chisagwiritsidwe ntchito pa ntchito zazikulu zothirira. Mapaipi a polyethylene nawonso amatha kusweka kuposa mapaipi a PVC. Kenako muyenera kusankha chitoliro chokhala ndi PSI rating 20-40 kuposa kupanikizika kosasinthasintha. Ngati makinawa akugwiritsidwa ntchito kwambiri, ndibwino kugwiritsa ntchito mulingo wapamwamba wa PSI kuti muwonetsetse kuti palibe zosokoneza zomwe zikuchitika.

Chitoliro cha polyethylene ndi chitoliro cha PEX ziyenera kugwiritsidwa ntchito m'malo osungiramo zinthu pansi pa nthaka.Mapaipi a PVC,Muyenera kubisa mapaipi a zinthuzi m'madzi osachepera mainchesi 10 kuti mupewe kufoshola ndi kuwonongeka nthawi yozizira. Kubisa mapaipi a polyethylene ndi PEX kumafuna mapulawu apadera, koma makina ambiri amtunduwu amatha kukumba mpaka mainchesi 10.

Chitoliro cha polyethylene ndi chitoliro cha PEX zitha kumangiriridwa ku mzere waukulu. Kuphatikiza apo, palinso zolumikizira zokankhira. Ma saddles akukhala njira yotchuka kwambiri yolumikizira polyethylene ndi machubu a PEX ku zothira madzi. Ngati mwasankha kugwiritsa ntchito chitoliro chomwe chimafuna kubowola, onetsetsani kuti mwayeretsa mapaipi bwino musanawamangirire ku chilichonse kuti muchotse pulasitiki yochulukirapo.
