Pipe dhayamita De, DN, d ф Zvinoreva
De, DN, d, ф Inomiririra inomiririra huwandu hwe
De - yekunze dhayamita yePPR, PE pombi uye polypropylene pombi
DN - Nominal dhayamita ye polyethylene (PVC) pombi, pombi yesimbi yakakandwa, simbi yepurasitiki inoumba pombi uye galvanized simbi pombi.
D -- zita dhayamita yepombi yekongiri
ф-- Iyo yezita dhayamita yepombi yesimbi isina musono ndeye ф 100:108 X 4
Musiyano pakati pepombi dhayamita DE uye DN
1. DN inoreva dhayamita rezita repombi, risiri iro dhayamita rekunze kana dhayamita yemukati (inofanirwa kunge iine hukama nezvikamu zvechirungu padanho rekutanga rekugadzirwa kweinjiniya yepombi, uye inowanzo shandiswa kutsanangura mapaipi esimbi). Hukama hwayo hunoenderana nemayunitsi echirungu hwakadai:
4/8 inch: DN15;
6/8 inch: DN20;
1 inch pipe: 1 inch: DN25;
Masendimita maviri pombi: 1 uye 1/4 inch: DN32;
Inch hafu pombi: 1 uye 1/2 inch: DN40;
Masendimita maviri pombi: 2 inch: DN50;
Masendimita matatu pombi: 3 inch: DN80 (yakanyorwawo seDN75 munzvimbo dzakawanda);
Pombi ina masendimita: 4 inch: DN100;
2. De inonyanya kureva dhayamita yekunze yepombi (kazhinji inotarwa neDe, iyo inofanirwa kuiswa muchimiro chekunze dhayamita X rusvingo ukobvu)
Inonyanya kushandiswa kutsanangura: seamless simbi mapaipi, PVC uye mamwe epurasitiki pombi, uye dzimwe pombi zvinoda yakajeka rusvingo ukobvu.
Kutora galvanized welded simbi pombi semuenzaniso, DN uye De yekumaka nzira dzinotevera:
DN20 De25X2.5mm
DN25 De32X3mm
DN32 De40X4mm
DN40 De50X4mm
Isu takajaira kushandisa DN kumaka mapombi esimbi, uye kashoma kushandisa De kumaka mapaipi pasina kubatanidza ukobvu hwemadziro;
Asi kutara pombi dzepurasitiki ndeimwe nyaya; Izvo zvakare zvine chekuita neiyo indasitiri maitiro. Mukuita kwekuvaka chaiko, iyo 20, 25, 32 nemamwe mapaipi atinodaidza anongoreva De, kwete DN.
Zvinoenderana nechiitiko chinoshanda pane saiti:
a. Nzira dzekubatanidza dzezvinhu zviviri zvepombi hazvisi chimwe chinhu kunze kwekusevha tambo yekubatanidza uye flange yekubatanidza.
b. Pombi yesimbi yakabatidzwa uye pombi yePPR inogona kubatanidzwa nenzira mbiri dziri pamusoro, asi shinda yescrew iri nyore kune mapaipi madiki pane makumi mashanu, uye flange inovimbika kune mapaipi akakura kupfuura makumi mashanu.
c. Kana mapaipi maviri esimbi akagadzirwa nezvinhu zvakasiyana akabatana, kana galvanic cell reaction ichaitika ichatariswa, zvikasadaro mwero wekuora wepombi dzesimbi dzinoshanda uchawedzera. Zviri nani kushandisa maflange ekubatanidza, uye kushandisa rubber gasket insulation zvinhu kuparadzanisa masimbi maviri, kusanganisira mabhaudhi, ane gaskets kudzivirira kubata.
Musiyano uripo pakati peDN, De naDg
DN Zita dhayamita
De kunze dhayamita
Dg dhayamita gongo. Dg dhayamita gong inogadzirwa muChina, ine maChinese maitiro, asi haichashandiswi
a. Nzira dzekumaka dzakasiyana dzepombi dzakasiyana:
1. Pamvura gasi kutapurirana simbi pombi (galvanized kana asina galvanized), akakandwa simbi pombi uye mamwe mapaipi, pombi dhayamita inofanira kuratidzwa nezita dhayamita DN (zvakadai DN15, DN50);
2. Seamless simbi mutopota, welded simbi nyere (yakatwasuka musono kana spiral musono), nyere yemhangura, Stainless simbi nyere uye dzimwe nyere, pombi dhayamita inofanira kuva D × Wall ukobvu (zvakadai D108 × 4, D159 × 4.5, etc.) ;
3. Kune yakasimbiswa kongiri (kana kongiri) pombi, ivhu pombi, asidhi inopikisa ceramic pombi, liner pombi uye mamwe mapaipi, iyo dhayamita yepombi inofanira kuratidzwa nepakati dhayamita d (senge d230, d380, nezvimwewo);
4. Pamapaipi epurasitiki, iyo dhayamita yepombi inofanira kuratidzwa maererano neyakagadzirwa chiyero;
5. Kana iyo dhayamita yezita reDN inoshandiswa kumiririra dhayamita yepombi mukugadzira, panofanira kuva netafura yekuenzanisa pakati pezita reDN dhayamita uye zvinoenderana nechigadzirwa.
b. Hukama hweDN, De uye Dg:
De ndiyo dhayamita yemadziro ekunze kwepombi
DN iDe minus hafu yeukobvu hwepombi madziro
Dg haisati yashandiswa
1 Pipe dhayamita ichave mumm.
2 Kureva kwedhayamita yepombi kunoenderana nezvinotevera:
1 Pamvura gasi kutapurirana simbi pombi (galvanized kana asina galvanized), cast iron pombi uye dzimwe pombi, pombi dhayamita inofanira kuratidzwa nezita dhayamita DN;
2 Seamless simbi pombi, welded simbi pombi (yakatwasuka musono kana spiral musono), mhangura pombi, Stainless simbi pombi uye dzimwe pombi, pombi dhayamita inofanira kuva kunze dhayamita × Wall ukobvu;
3 Papombi dzekongiri dzakasimbiswa (kana kongiri), pombi dzevhu, pombi dzedongo dzisingachinji asidhi, pombi dzemapaipi nedzimwe pombi, dhayamita yepombi inofanira kuratidzwa nedhayamita yemukati d;
4 Kune mapaipi epurasitiki, iyo dhayamita yepombi inofanira kuratidzwa maererano neyakagadzirwa chiyero;
5 Kana iyo dhayamita yezita DN ichishandiswa kumiririra dhayamita yepombi mudhizaini, tafura yekuenzanisa pakati pezita redhiyamita DN uye zvinoenderana nechigadzirwa chinopihwa.
Unplasticized polyvinyl chloride mapaipi ekuvaka drainage - de (zita rekunze dhayamita) kune yakatarwa × E (zita remadziro ukobvu) zvinoreva (GB 5836.1-92).
Polypropylene (PP) mapaipi ekupa mvura × E inomirira (zita rekunze dhayamita × Ukobvu hwemadziro)
