Iimpazamo eziqhelekileyo kwaye zibangele uhlalutyo lweevali zonyango lwamanzi

Emva kokuba ivalve iye yasebenza kwinethiwekhi ye-pipeline kangangexesha elithile, kuya kwenzeka ngeentsilelo ezahlukeneyo. Inani lezizathu zokusilela kwevalve inxulumene nenani leenxalenye ezenza ivalve. Ukuba kukho iinxalenye ezininzi, kuya kubakho ukusilela okuqhelekileyo; Ukufakwa, ukusebenza ngendlela yokusebenza, kunye nesondlo zinxulumene nomnye. Ngokubanzi, ukusilela okuqhelekileyo kweevalve ezingekhombane zinokwenziwa malunga nezigaba zine zilandelayo.

1. Iivalveumzimba wonakalisiwe kwaye uqhekezwe

Izizathu zomonakalo womzimba weValve kunye ne-Rupture: Ukucukucezwa kokuhlekisa kweivalveizixhobo; indawo yokuhlala isiseko; utshintsho olukhulu kwi-Pipe Network yoxinzelelo lwenethiwekhi okanye umahluko wobushushu ubushushu; I-Hammer yamanzi; Umsebenzi ongafanelekanga wokuvala iivila, njl.

Isizathu sangaphandle kufuneka sisuswe ngexesha kwaye uhlobo olufanayo lwe-valve okanye ivalve kufuneka itshintshwe.

2. Ukusilela kokuhambisa

Ukusilela kokuhambisa kuhlala kubonakala njengezitya, ukusebenza okuqinileyo, okanye i-valdes engalunganga.

Izizathu zezi: Iivalveirhabaxa emva kokuba ivaliwe ixesha elide; Intambo ye-valve stem okanye i-stem net yonakaliswa kukufakelwa okungafanelekanga kunye nokusebenza; Isango linamathele emzimbeni wevali, ngomcimbi wangaphandle; IivalveIsikhephe se-stemp kwaye i-valve stene wire yocingo lingasebenzi, likhululwe; Ukupakisha kucinezelwa ngokuqinileyo kwaye i-valve sup itshixiwe; I-valve stem ityhalelwe ekufeni okanye inamalungu aliyo.

Ngexesha lolondolozo, indawo yokuhambisa kufuneka inyibilike. Ngoncedo lomngxunya, kunye nokupeyiphu kancinci, into entle yokutsaleka kunye nejeki inokupheliswa; Misa amanzi ukuze ugcine okanye utshintshe ivalve.

I-3. Ukuvula ivalve engalunganga kunye nokuvala

Ukuvulwa okubi nokuvalwa kweivalveibonakaliswa yinyani yokuba ivalve ayinakuvulwa okanye ivaliwe, kunye neivalveAyikwazi ukusebenza ngokwesiqhelo.

Izizathu zezi: Iivalveisiqu siphilisiwe; Isango linamathele okanye lirhatyaze xa isango livaliwe ixesha elide; Isango liyawa; into yangaphandle ibambekile kumhlaba wokutywina okanye ukutywina i-roove; Inxalenye yokuhambisa inxitywe kwaye ivaliwe.

Xa udibana nale meko ingentla, unokulungisa kwaye unciphise iindawo zokuhambisa; vula kwaye uvale ivalve ephindaphindiweyo kwaye wothuke izinto zangaphandle ngamanzi; okanye faka ivalve.

4. Iivalveiyavuza

Ukuvuza kweveli kubonakaliswa njenge: Ukuvuza kwe-valve stem gore; ukuvuza kwe-gland; ukuvuza kwe-rande yerabha yeflethi.

Izizathu eziqhelekileyo zezi: I-valve stem (i-chall ye-vall) inxitywe, ifakwe kwaye ifakwe ngaphandle, imingxunya kunye nokuthululwa kubonakala kumhlaba wokutywina; Itywina liyaluphala kwaye livuza; I-Gland Bolts kunye ne-Bolts uqhagamshelo lweFlanges zikhululekile.

Ngexesha lolondolozo, i-wiprium ephathekayo inokongezwa kwaye itshintshwe; Amandongomane amatsha anokutshintshwa ukuze asebenzise isikhundla sezibuko ezikhawulezayo.

Nokuba loluphi uhlobo lokungaphumeleli, ukuba alulungiswa kwaye lulondolozwe ekuhambeni kwexesha, lunokubangela ubutyebi bamanzi, kwaye kongezeleleke ngakumbi, kubangela ukuba inkqubo ikhubazekile. Ke ngoko, abasebenzi bokulungisa i-valve kufuneka balwazi unobangela wokusilela kwe-veli, bakwazi ukuhlengahlengisa i-valve kwaye ngokuchanileyo, ukujongana nokusilela ngendlela engxamisekileyo, kunye nokuqinisekisa ukusebenza kwesiqhelo kwinethiwekhi yombhobho wamayeza.
