4.Ukwakhiwa ebusika, uvavanyo loxinzelelo lwamanzi kwiqondo lokushisa elingaphantsi kwe-zero.

Isiphumo: Ngenxa yokuba iqondo lokushisa lingaphantsi kwe-zero, umbhobho uya kukhenkceza ngokukhawuleza ngexesha lovavanyo lwe-hydraulic, olunokubangela ukuba umbhobho ube ngumkhenkce kwaye uqhekeke.

Amanyathelo: Zama ukwenza uvavanyo loxinzelelo lwamanzi phambi kokwakhiwa ebusika, kwaye ususe amanzi kumbhobho kunye nevalve emva kovavanyo loxinzelelo, kungenjalo isivalo sinokurusa, kwaye ubungozi bunokukhokelela kwintanda yomkhenkce.

I-5.I-flange kunye ne-gasket yokudibanisa kombhobho ayinamandla ngokwaneleyo, kwaye iibholiti zokudibanisa zifutshane okanye zincinci ububanzi. I-Rubber pad isetyenziselwa umbhobho wokushisa, i-double pad okanye i-pad ethambekele isetyenziselwa umbhobho wamanzi abandayo, kunye ne-flange pad iqhekeza kumbhobho.

Iziphumo: i-flange joint ayiqinanga, kwaye yonakaliswe, isiganeko sokuvuza. I-gasket ye-flange ephuma kumbhobho iya kwandisa ukumelana nokuhamba.

Imilinganiselo: Iiflange zemibhobho kunye neegaskets kufuneka zihlangabezane neemfuno zoyilo lwemibhobho yoxinzelelo lokusebenza.

Iigaskets zeflange zokufudumeza kunye nemibhobho yokubonelela ngamanzi ashushu kufuneka ibe yi-rubber asbestos gaskets; I-flange gasket yonikezelo lwamanzi kunye nombhobho wokuhambisa amanzi kufuneka ibe yi-rubber gasket.

Umgca we-flange awuyi kuqhuma kwi-tube, kwaye isangqa sangaphandle kufuneka sijikelezwe kwi-bolt hole ye-flange. Akukho pad ethotyiweyo okanye iigaskets ezininzi ziya kubekwa embindini weflange. Ububanzi bebholiti edibanisa i-flange kufuneka ibe ngaphantsi kwe-2mm xa kuthelekiswa ne-aperture ye-flange. Ubude be-nut ephumayo yentonga ye-bolt kufuneka ibe yi-1/2 yobunzima be-nut.

6. Ugutyulo lwamanzi amdaka, amanzi emvula, imibhobho yecondensate ayenzi uvavanyo lwamanzi oluvaliweyo luya kufihlwa.

Iziphumo: Isenokuvuza, kwaye ibangele ilahleko yabasebenzisi. Ukugcina kunzima.

Imilinganiselo: Uvavanyo lwamanzi avaliweyo kufuneka luhlolwe kwaye lwamkelwe ngokungqongqo ngokweenkcukacha. Ukungcwatywa ngaphantsi komhlaba, kwisilingi, phakathi kwemibhobho kunye namanye amdaka afihliweyo, amanzi emvula, imibhobho ye-condensate, njl., Ukuqinisekisa ukuba akukho kuvuza.

7. Ukuvula nokuvalwa kwevalve ngesandla, amandla agqithisileyo
Iziphumo: umonakalo wevalve ekhanyayo, unzima uya kukhokelela kwiingozi zokhuseleko

Amanyathelo:

Ivili lesandla okanye isibambo se-valve ye-manual yenzelwe ngokuhambelana nabasebenzi abaqhelekileyo, kuthathelwa ingqalelo amandla omgangatho wokutywina kunye namandla okuvala ayimfuneko. Ngoko awukwazi ukusebenzisa imilenze emide okanye izandla ezinde ukuhambisa ibhodi. Abo bajwayele ukusebenzisa i-wrenches kufuneka bahlawule ngokungqongqo ukuba bangasebenzisi amandla amaninzi, ngaphandle koko kulula ukulimaza indawo yokutywina, okanye ukuphula i-handwheel kunye nokusingatha. Vula kwaye uvale i-valve, amandla kufuneka agudileyo, angabi nempembelelo enamandla. Kwi-valve ye-steam, ngaphambi kokuvula, kufuneka ifudunyezwe kwangaphambili, kwaye i-condensate kufuneka ikhutshwe, kwaye xa ivula, kufuneka ihambe ngokukhawuleza ukuphepha ukwenzeka kwesando samanzi.

Xa i-valve ivuliwe ngokupheleleyo, i-handwheel kufuneka iguqulwe kancinane, ukwenzela ukuba intambo phakathi kwe-tight, ukuze ingakhululeki umonakalo. Kwiivalvu zesiqu esivulekileyo, khumbula ukuma kwesikhondo xa sivuleke ngokupheleleyo kwaye sivalwe ngokupheleleyo ukunqanda ukubetha iziko eliphezulu elifileyo xa livuleke ngokupheleleyo. Kwaye kulula ukujonga ukuba ukuvalwa ngokupheleleyo kuqhelekile. Ukuba i-disc iyawa, okanye i-debris enkulu ifakwe phakathi kwesitywina se-spool, indawo ye-valve stem kufuneka itshintshwe xa i-valve ivalwe ngokupheleleyo.

Xa umbhobho usetyenziswa okokuqala, kukho ukungcola okungaphezulu kwangaphakathi, ivalve inokuvulwa kancinci, isantya esiphezulu sokuhamba kwesixhobo singasetyenziselwa ukuyihlamba, kwaye emva koko ivalwe ngobunono (ayinakuvalwa ngokukhawuleza, ukuthintela intsalela. ukungcola ekulimazeni umphezulu wokutywina), kwaye emva koko wavula kwakhona, ngokuphindaphindiweyo amaxesha amaninzi, ukugungxula ukungcola, kwaye emva koko kufakwe kumsebenzi oqhelekileyo. Ngokuqhelekileyo uvule i-valve, indawo yokutywina inokubambelela kwizinto ezingcolileyo, kwaye kufuneka ihlanjwe ihlambuluke ngale ndlela ingentla xa ivaliwe, kwaye ivalwe ngokusemthethweni.

Ukuba i-handwheel okanye i-handwheel yonakalisiwe okanye ilahleka, kufuneka ifaniswe ngokukhawuleza, kwaye ayikwazi ukutshintshwa yi-flexible plate hand, ukwenzela ukuba ugweme umonakalo kwi-valve stem kunye nokusilela ukuvula nokuvala, okubangela iingozi kwimveliso. Eminye imidiya, emva kokuba ivalve ivaliwe ukupholisa, ukwenzela ukuba iindawo zevalve ziyancipha, umqhubi kufuneka aphinde avaliwe ngexesha elifanelekileyo, ukwenzela ukuba indawo yokutywina ingashiyi i-seam ecocekileyo, ngaphandle koko, i-medium ukusuka kwi-fine seam flow. ngesantya esiphezulu, kulula ukutshabalalisa indawo yokutywina.

Ukuba ufumanisa ukuba olu tyando lunzima kakhulu, hlalutya unobangela. Ukuba ukupakisha kuqinile kakhulu, kunokukhululeka ngokufanelekileyo, njenge-valve stem skew, kufuneka yazise abasebenzi ukuba balungise. Ezinye iivalve, kwimeko evaliweyo, inxalenye yokuvala yandiswa ngokushisa, okubangela ubunzima ekuvuleni; Ukuba kufuneka ivulwe ngeli xesha, ungakhulula intambo yesigqubuthelo sevalve isiqingatha ukujika ukuya kwelinye ithuba, susa uxinzelelo lwesiqu, kwaye emva koko tsala ivili lesandla.
