Ubomi benkonzo ende kunye nexesha lokugcinwa lingenalo liya kuxhomekeka kwezi zinto zilandelayo: iimeko eziqhelekileyo zokusebenza, ukugcina umlinganiselo wokushisa ohambelanayo / uxinzelelo, kunye nedatha ye-corrosion efanelekileyo.
Xa ivalve yebhola ivaliwe, kusekho ulwelo loxinzelelo kumzimba wevalvu.
Ngaphambi kokugcinwa: khulula uxinzelelo lombhobho, gcina ivalve kwindawo evulekileyo, qhawula amandla okanye umthombo womoya, kwaye uhlukanise i-actuator kwisibiyeli.
Ngaphambi kokuqhaqha kunye nokusebenza kokubola, uxinzelelo lwemibhobho ephuma phezulu nasezantsi yevalve yebhola kufuneka ihlolwe.
Ngexesha lokuqhawula kunye nokudibanisa kwakhona, kufuneka kuthathelwe ingqalelo ukuthintela umonakalo kwiindawo zokutywinwa kwamacandelo, ngokukodwa iindawo ezingenazo isinyithi.Izixhobo ezikhethekileyo kufuneka zisetyenziswe xa kususwa i-O-rings.
Iibholiti kwi-flange kufuneka ziqiniswe ngokulinganayo, ngokuthe ngcembe, kwaye ngokulinganayo.
I-arhente yokucoca kufuneka ihambelane nerubha yevalve yebhola, iplastiki, isinyithi, kunye nesixhobo sokusebenza (njengegesi).Xa i-medium yokusebenza igesi, iinxalenye zetsimbi zinokucocwa ngepetroli (GB484-89).Coca iindawo ezingezizo isinyithi ngamanzi acocekileyo okanye utywala.
Amalungu angenawo isinyithi kufuneka asuswe kwi-arhente yokucoca ngokukhawuleza, kwaye akufanele afakwe ixesha elide.
Emva kokucoca, kuyimfuneko ukuvuthisa i-agent yokucoca udonga (sula ngelaphu lesilika elingazange lifakwe kwi-arhente yokucoca) ukuze lihlanganise, kodwa akufanele libekwe ixesha elide, ngaphandle koko, liya kuhlwa kwaye ungcoliswe luthuli.
Amalungu amatsha nawo afanele acocwe ngaphambi kokuba adibane.
Ngethuba lenkqubo yokuhlanganisana, akufuneki kubekho i-debris yensimbi, i-fibers, i-oyile (ngaphandle kokusetyenziswa okuchaziweyo), uthuli kunye nezinye izinto ezingcolileyo, izinto zangaphandle, kunye nolunye ukungcola, ukunamathela okanye ukuhlala phezu kwendawo okanye ukungena kwindawo yangaphakathi.Tshixa isiqu kunye ne nut ukuba kukho ukuvuza okuncinci ekupakisheni.
A), ukudilizwa
Qaphela: Sukutshixa kakhulu, ngokuqhelekileyo i-1/4 ukuya kwi-1 ngaphezulu ukujika, ukuvuza kuya kuyeka.
Beka ivalve kwindawo evuleke-ngesiqingatha, gungxula, kwaye ususe izinto eziyingozi ezinokuthi zibekho ngaphakathi nangaphandle kwesivalo somzimba.
Vala i-valve yebhola, susa i-bolts yokudibanisa kunye namantongomane kwi-flanges kumacala omabini, uze ususe ngokupheleleyo i-valve kumbhobho.
Ukuqhawula isixhobo sokuqhuba ngokutshintshana - i-actuator, isibiyeli sokudibanisa, iwasha yokutshixa, i-stem nut, i-butterfly shrapnel, i-glam, i-sheet-resistant sheet, ukupakishwa kwesiqu.
Susa isigqubuthelo somzimba iibholiti zokudibanisa kunye namandongomane, yahlula isigqubuthelo sevalvu kumzimba wevalvu, kwaye ususe igasket yesivalo sevalve.
Qinisekisa ukuba ibhola ikwindawo evaliweyo, eyenza kube lula ukuyisusa emzimbeni, uze ususe isihlalo.
Tyhila isiqu sevalve ezantsi kumngxuma kumzimba wevalvu de sisuswe ngokupheleleyo, kwaye emva koko ukhuphe i-O-ring kunye nokupakishwa phantsi kwesikhondo sevalve.
B), hlanganisana kwakhona.
Qaphela: Nceda usebenze ngononophelo ukuze ungakrwala umphezulu wesiqu sevalve kunye nenxalenye yokutywina yebhokisi yokuhlohla yevalve yomzimba.
Ukucocwa kunye nokuhlolwa kweendawo ezichithwayo, kucetyiswa ngamandla ukuba utshintshe izitywina ezifana nezihlalo ze-valve, i-bonnet gaskets, njl.
Hlanganisa ngokulandelelana kwe-disassembly.
Gxininisa iibholiti zokudibanisa i-flange kunye ne-torque echaziweyo.
Qinisa i-stem nut ngetorque echaziweyo.
Emva kokufaka i-actuator, faka isignali ehambelanayo, kwaye uqhube i-valve core ukujikeleza ngokujikeleza i-valve stem, ukuze i-valve ifike kwindawo yokutshintsha.
Ukuba kunokwenzeka, nceda wenze uvavanyo lokutywinwa koxinzelelo kunye novavanyo lokusebenza kwivalve ngokwemigangatho efanelekileyo phambi kokuba uphinde ufakele umbhobho.
