Chinhu chinonyanya kukosha pakushanda nePVC pombi uye fittings ndiyo saizi yezita.A 1" fitting ichakwana pa 1" pombi, zvisinei nekuti imwe iri schedule 40 kana 80. Saka, nepo 1" socket fitting ine kuvhura kwakafara kupfuura 1" mhiri, inokwana pa 1" pombi nokuti OD yepombi iyoyo yakakurawo kupfuura 1".
Panogona kusvika nguva yaunoda kushandisa PVC inokwana ine isiri-PVC pombi.Saizi yezita, mune iyi kesi, haina kukosha seOD yepombi yauri kushandisa.Chero bedzi iyo OD yepombi yakafanana neyemukati dhayamita (ID) yekukodzera iyo iri kupinda mairi, ivo vanozoenderana.Nekudaro, 1 "yakakodzera uye 1" kabhoni simbi pombi inogona kusapindirana neimwe neimwe nekuda kwekuti ine saizi yezita.Iva nechokwadi chekuita tsvakurudzo yako usati washandisa mari pane zvikamu zvingave zvisingaenderani kune mumwe nemumwe!
Pasina chero zvinonamira, pombi yePVC uye mafittings anokwana pamwe chete zvakanaka.Ivo havazove, zvisinei, kuva vasina mvura.Kana iwe uchizove nechero mvura inopfuura nepapombi yako, iwe uchada kuona kuti hapazove nekudonha.Pane nzira dzakasiyana siyana dzekuita izvi, uye nzira yaunosarudza ichaenderana nezvauri kubatanidza.
PVC pombi pachayo haina kazhinji ine threaded magumo.Ichi ndicho chikonzero chimwe chete chekuti maPVC mafittings akawanda ane magumo anotsvedza."Kutsvedza" muPVC hazvireve kuti kubatana kuchatsvedza, asi kuti iyo yekuisa ichatsvedza pamusoro pepombi.Kana uchiisa pombi mune inotsvedza inokodzera, iyo yekubatanidza inogona kuita seyakasimba, asi kutakura chero mvura midhiya, inoda kuvharwa.PVC simende inovhara pombi kuburikidza nekemikari reaction inosunga purasitiki yeimwe chikamu kune imwe.Kuti uwane chisimbiso chakavimbiswa pane inotsvedza, iwe uchada ese PVC primer uye PVC simende.Iyo primer inopfavisa mukati mekukodzera, ichigadzirira kuti ibatane, nepo simenti ichichengeta zvidimbu zviviri zvakanamatirana zvakasimba.
Threaded fittings inoda kuiswa chisimbiso zvakasiyana.Chikonzero chikuru chinoita kuti vanhu vashandise zvidimbu zvakakanyiwa ndezvekuti zvibviswe kana zvichidikanwa.PVC simende zvisungo pombi pamwe chete, saka kana ikashandiswa pamajoini akarukwa, ichaita chisimbiso, asi tambo dzinoshaya basa.Nzira yakanaka yekusimbisa majoini ane thread uye arambe achishanda ndeye kushandisa PTFE thread seal tepi.Ingoiputira patambo dzechirume nguva shoma uye inochengeta kubatana kwakavharwa uye nekuzorwa.Uye kana iwe uchida kudzoka kune iyo joint kuti igadziriswe, zvigadziridzo zvicharamba zvichikwanisa kusunungura.
Kazhinji vatengi vedu vanotibvunza kuti, "Ndechipi musiyano pakati pefenicha yegiredhi fittings uye yenguva dzose fittings?"Mhinduro iri nyore: yedu fenicha giredhi fittings haina mugadziri anodhinda kana bar kodhi.Iwo akachena machena kana nhema asina chakadhindwa paari.Izvi zvinoita kuti zvive zvakanaka kune zvikumbiro apo pombi ichaonekwa, ingave iri yefenicha kana kwete.Saizi yacho yakafanana neyakajairwa saizi yakakodzera.Semuyenzaniso, 1" giredhi rekukwana fenicha uye 1" yenguva dzose inokwana zvese zvichakwana papombi 1. Zvakare, zvinogara zvakangofanana nezvimwe zvese zvePVC.
Inotevera rondedzero yemamwe anonyanya kushandiswa PVC fittings aripo.Yese yekupinda ine tsananguro yekukodzera pamwe nekugona kushandiswa uye mashandisiro ayo.Kuti uwane rumwe ruzivo nezve chero cheizvi zvigadziriso, shanyira avo akasiyana chigadzirwa mapeji.Zvakakosha kuyeuka kuti imwe neimwe yekukodzera ine huwandu husingaverengeki hwekudzokororwa uye kushandiswa, saka chengeta izvo mupfungwa paunenge uchitenga zvekushandisa.
PVC tees inokodzera ine migumo mitatu;maviri mumutsara wakatwasuka uye imwe parutivi pakona ye90-degree.Tee dzinobvumira mutsetse kuti upatsanurwe kuita mitsetse miviri yakasiyana ine 90-degree connection.Zvakare, ma tee anogona kubatanidza mitsetse miviri mumutsara mumwe mukuru.Ivo zvakare vanowanzoshandiswa kune PVC zvimiro.Tee ndeyekukodzera kwakasiyana-siyana izvo zvimwe zvezvinonyanya kushandiswa zvikamu mupombi dzemvura.Mazhinji ma tee ane slip socket ends, asi ma threaded versions aripo.
