Sab Nrauv sab nraum zoov hlau 2 Txoj kev hluav taws kub HiCant BS750

1. Tiv taus kev cuam tshuam thiab tsawg dua rau kev puas tsuaj, txo tus nqi kho

Qhov kev cuam tshuam nyuaj ntawm cov hlau khi yog 3 {{{- 5 zaug ntawm kev sib tsoo hauv tsheb, hnyav lub cuab yeej kev sib tsoo). Nws tsis tshua muaj feem yuav ua kom tawg lossis tawg. Tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam nrog cov tsheb neeg taug kev los kav (xws li cov zaus ntawm cov neeg zej zog lossis hloov cov cuab yeej siv kev puas tsuaj, thiab ntev txo cov nuj nqis.

2. High corrosion tsis kam thiab ntev kev pabcuam lub neej

Spheroidal graphite hlau nws tus kheej muaj qee yam tsis kam mus rau atmospheric corrosion thiab av hauv av. Yog tias nws undergoes anti {- kev kho corrosion xws li cov av hauv av thiab sab nraud, thiab cov khoom siv sab nrauv.

3. Kev seading kev ua tau zoo yog ruaj khov thiab kev ntseeg tau thaum muaj xwm txheej ceev yog siab.

Tus tub ntxhais muaj nuj nqi ntawm cov hluav taws kub hydrant yog "mov dej kub". Cov khoom siv ntawm cov hlau muaj qhov ruaj khov kho thiab kev ua kom yooj yim los tswj, uas tuaj yeem ua kom pom tau cov khoom nplaum thiab lub raj hluav taws xob txhua hnub (zam cov khoom pov tseg dej); Ntxiv mus, nyob rau hauv cov xwm txheej kub ntxhov xws li hluav taws kub, nws yuav tsis ua rau muaj kev tsis txaus siab vim tias cov khoom siv hluav taws kub tuaj yeem tau txais dej.

4. Kev yoog tau, yooj yim installation thiab txij nkawm

Cov txheej txheem casting ntawm cov hlau cooting yog paub tab, ua kom meej meej tsim muaj kev cuam tshuam ntawm ntau yam kev sib cuam tshuam (xws li DN100, thiab lwm yam ntawm diameters). Nws tuaj yeem hloov chaw rau cov raj hluav taws xob uas twb muaj lawm tua hluav taws thiab dej haus dej; Nyob rau tib lub sijhawm, cov pob hlau cov khoom muaj qhov hnyav hnyav (sib dua dua li cov hlau thiab yooj yim dua thaum cam cam khwb cia hlau hlau), thiab tsis muaj kev nyuaj ntawm kev tsim kho.
