Li-valve tsa serurubele li sebelisoa haholo phepelong ea metsi, ho hloekisa metsi a litšila le kalafong ea lik'hemik'hale. Hobane li na le moralo o bonolo, sebelisa lisebelisoa hantle, li nyane, ebile li theko e tlase.
Ho kenya li-valve ka mokhoa o nepahetseng ho tiisa ts'ebetso e nepahetseng le bophelo bo bolelele. Pele o kenya valve ea serurubele, mokhoa oa ho kenya o tlameha ho utloisisoa.Nakong ea ho kenya, uena ea ratehang o boetse o tlameha ho latela mehato ea tšireletso.
1. Mokhoa oa ho kenya valve ea serurubele holim'a phala?
a)Lisebelisoa tse hlokahalang
Ho kenya valve ea serurubele ho hloka lisebelisoa tse fapaneng ho thusa.
- Li-wrenches li tiisa liboutu.
-Li-wrenches tsa torque li hlahloba hore na ho kenngoa ho ka har'a sebaka se loketseng sa torque.
-Li-Screwdrivers li sireletsa likarolo tse nyane.
-Lipeipi li etsa libaka tsa ho kenya li-valve tsa serurubele.
-Liatlana tsa tšireletso le likhalase li thibela likotsi tse ka bang teng.
-Boemo le sekoti: Netefatsa hore valve ea serurubele e kentsoe ka tsela e nepahetseng.
b) Thepa e hlokahalang
-Ho hlokahala lisebelisoa tse khethehileng bakeng sa ho kenya.
- Li-gaskets li tiisa valve ea serurubele le flange hantle.
-Bolts le linate li sireletsa valve ea serurubele ho pipe.
- Lisebelisoa tsa ho hloekisa li tlosa lithōle ho tloha liphaephe le li-valve tse entsoeng nakong ea ho kenya.
2. Mehato ea ho Itokisa
Ho hlahloba Valofo ea Butterfly
-Ho hlahloba valve ea serurubele pele u kenya ke mohato oa bohlokoa. Moetsi o hlahloba valve e 'ngoe le e' ngoe ea serurubele pele e romeloa. Leha ho le joalo, mathata a ntse a ka hlaha.
-Hlahloba valve ea serurubele bakeng sa tšenyo leha e le efe e bonahalang kapa likoli.
-Etsa bonnete ba hore disc ea valve e potoloha ka bolokolohi 'me ha e khomarele.
- Netefatsa hore setulo sa valve se ntse se le teng.
-Sheba hore boholo ba valve le khatello ea eona li lumellana le lintlha tsa phaephe.
Lokisetsa Sisteme ea Pipeline
Feela joalokaha ho le bohlokoa ho hlahloba valve ea serurubele ke ho hlahloba phaephe.
- Hloekisa lipeipi ho tlosa mafome, litšila le litšila.
-Sheba ho tsamaisana ha liphaephe tse kopanyang.
-Etsa bonnete ba hore li-flange li boreleli ebile li bataletse ntle le li-burrs.
- Netefatsa hore phaephe e ka tšehetsa boima ba valve ea serurubele, haholo-holo bakeng sa li-valve tse kholo. Haeba ho se joalo, sebelisa bracket e khethehileng.
3. Ts'ebetso ea ho kenya
a) Ho beha Valve ea Butterfly
Beha belofo ea serurubele ka nepo pompong.
The valve disc e bulehile hanyenyane ho qoba ho e senya kapa setulo ha se petetsa. Haeba ho hlokahala, sebelisa flange e khethehileng e etselitsoeng li-valve tsa mofuta oa serurubele. Sesepa sa valve se bulehile hanyenyane ho qoba ho senya diski ea valve kapa setulo sa valve ha u petetsa setulo sa valve.
Sheba mokhoa
Netefatsa hore valve ea serurubele e kentsoe ka tsela e nepahetseng.
Li-valve tsa serurubele sa Centerline hangata ke li-valve tsa serurubele tse mabili. Li-valve tsa serurubele sa Eccentric hangata ha li na tsela ntle le haeba ho hlokahala ka tsela e 'ngoe.Taelo ea phallo ea seaplane e lokela ho ts'oana le motsu holim'a 'mele oa valve, e le ho netefatsa phello ea tiiso ea setulo sa valve.
Ho lokisa valve ea serurubele
Kenya liboutu ka masoba a flange a belofo ea serurubele le phaephe. Etsa bonnete ba hore belofo ea serurubele e tsamaea le phaephe.Ebe u li tiisa ka ho lekana.
Ho tiisa liboutu ka naleli kapa naleli ea sefapano (ke hore, diagonal) ka mokhoa o tšoanang ho ka aba khatello ka ho lekana.
Sebelisa torque wrench ho fihlela torque e boletsoeng bakeng sa bolt ka 'ngoe.
Qoba ho tiisa ho feta tekano, ho seng joalo e tla senya valve kapa flange.
Hokela sesebelisoa se thusang sa actuator actuator
Kopanya phepelo ea motlakase hloohong ea motlakase. Hape, hokela mohloli oa moea hloohong ea moea.
Tlhokomeliso: The actuator ka boeona (sebapa, lisebelisoa tsa liboko, hlooho ea motlakase, hlooho ea pneumatic) e fetotsoe le ho lokisoa bakeng sa valve ea serurubele pele e romelloa.
Tlhahlobo ea ho qetela
-Sheba hore na valve ea serurubele le pipeline li na le matšoao a ho se tsamaisane kapa ho senyeha.
- Netefatsa hore valve e sebetsa hantle ka ho bula le ho koala valve ka makhetlo a 'maloa. Ebang disc ea valve e ka potoloha ka bolokolohi ntle le tšitiso leha e le efe kapa khanyetso e feteletseng.
-Sheba libaka tsohle tsa khokahano bakeng sa ho lutla. U ka etsa tlhahlobo ea ho lutla ka ho hatella phaephe eohle.
-Etsa liphetoho tse hlokahalang ho netefatsa ts'ebetso e nepahetseng.
Ho rarolla mathata a tloaelehileng
Belofo ea serurubele ha e bulehe kapa ha e koalehe hantle: Sheba hore na ha ho na lintho tse thibileng peipi. Hape, hlahloba matla a motlakase a actuator le khatello ea moea.
Ho dutla kgokelong: Sheba hore na bokahodimo ba phaepe ha bo a lekana. Hape, hlahloba hore na liboutu li tiisitsoe ka tsela e sa lekanang kapa li hlephile.
Ho kenya le tlhokomelo e nepahetseng ho netefatsa hore valve ea serurubele e sebetsa ka katleho mesebetsing e fapaneng. Ts'ebetso ea ho kenya valve ea serurubele e kenyelletsa mehato e mengata ea bohlokoa. Ho hloekisa pele ho ho kenya, ho lumellana hantle, ho lokisa le ho hlahloba ho qetela ho netefatsa ts'ebetso e nepahetseng. Ithute ka hloko 'me u latele mehato ena pele u qala ho kenya. Ho etsa joalo ho ka thibela mathata le likotsi.
Etsoe ho na le maele a khale a Sechaena a reng "ho leotsa thipa ha ho liehe ho rema patsi."
