Tswb Kos Lub Pob Valve Yog Dab Tsi?
Lub tswb ntsuas tswb (ACV) yog ib lub pob tshwj xeeb tsim los pab cov dej tiv thaiv hluav taws kub: tiv thaiv rov qab dej thiab ua kom lub zog. Feem ntau siv nyob rau hauv cov dej ntws ntub dej hluav taws xob cov nroj tsuag, qhov twg pipes nyob twj ywm hauv kev kub ntxhov, cov acv ua kom pom kev siv hluav taws xob thiab cov neeg tuaj yeem ceev lossis cov neeg tuaj yeem pab pawg ceev. Nws cov qauv ua ke cov ntsiab cai ntawm daim tshev valve (tiv thaiv rov qab cov natural) nrog kev tiv thaiv kev nyab xeeb, kev lag luam hauv cov lag luam, thiab vaj tse.
Cov Acv muaj ob peb ntu tseem ceeb:
- Lub cev lub cev: muab faib ua sab saud (sab nraud sab) thiab qis dua (dej rau sab)
- Clapper Assembly: A hinged disc that opens when water pressure in the supply side exceeds system-side pressure, allowing flow.
- Chaw nres nkoj Tswb: txuas rau lub tswb ntaus ntawv (piv txwv li, dej tsav tsheb gong lossis siab hloov) ntawm nruab nrab Chamber.
- Retard Chamber: ib qho me me pas dej uas qeeb qeeb qeeb tiv thaiv kom tiv thaiv cov tswb cuav lossis cov rauj hluav taws xob.
Kev phais:
- Nyob rau hauv ib txwm mob, cov npuaj taw tseem kaw, tswj cov txheej txheem siab thiab thaiv cov thaub qab.
- Thaum cov kais tsuag dej uas muaj dej ntws tawm, cov dej ntws tawm ntawm cov khoom xa mus rau sab kab ke, nqa cov npuaj.
- Dej nkag mus rau hauv nruab nrab Chamber, nias lub tswb. Cov chiv no yog:
- Ib lub tshuab kho tshuab (xws li dej, uas siv cov dej ntws kom tig lub rauj tawm tsam lub tswb).
- Lub tswb hluav taws xob (piv txwv li, siab hloov xa cov teeb liab rau lub tswb hluav taws xob tswj vaj huam sib luag).
- Lub chanard charaig ib ntus tuav cov dej ntau dhau thaum lub sij hawm me ntsis kev hloov pauv, tso nws los ntawm qhov chaw nres nkoj ntws tsis muaj suab nrov.
1. Backflow Kev Tiv Thaiv
ACV kom cov dej ntws tawm tsuas yog rau cov kais tsuag dej, tiv thaiv kev tiv thaiv kev ua paug (piv txwv li, cov khib nyiab lossis khib nyiab hauv cov kab ke). Qhov no ua kom haum nrog cov kav dej kav dej uas xav tau cov khoom siv tiv thaiv backflow.
2. Kev ua kom muaj zog
Los ntawm kev tshawb nrhiav dej txav, ACV muab cov ntawv ceeb toom tam sim ntawd, ua kom cov lus teb sai sai thiab kev khiav tawm hluav taws xob sai sai. Cov tshuab hluav taws xob (zoo li cov tub rog (zoo li GONS) yog audible txawm tias thaum lub zog hluav taws xob, thaum hluav taws xob tswb ua ke nrog kev ua tshuab tshuab.
3. Kev qhia txog lub tswb nrov
Lub limtiam Retard tawm ntawm kev hloov pauv hloov pauv, txo kev kub ntxhov ntawm lub tswb los ntawm 90% hauv kev sim. Qhov kev txhim kho cov txheej txheem kev ntseeg tau thiab zam kev tsis tsim nyog tau xa tawm tsis tas.
4. Kev Tu Siab
ACV pab kom cov txheej txheem zoo siab, kom cov kais dej tawm kom zoo thaum cov hluav taws kub. Nws cov qauv siv minimizes lub siab ua kom qis, txawm tias nyob hauv cov tsev loj nrog cov piping sib txuas.
