Likopo tse Ncha tse cheselitsoeng tsa Balofo ea Likotoana tse peli bakeng sa Mocheso o Phahameng, Tikoloho ea Khatello e Phahameng
1. Selelekela
Li-valve ke lisebelisoa tsa bohlokoa tse sebelisoang ho laola phallo ea mokelikeli, khatello le tataiso ea phallo lits'ebetsong tsa phallo ea mokelikeli. Li sebelisoa haholo ho petroleum, lik'hemik'hale, matla a motlakase, metallurgy le liindasteri tse ling. Libakeng tse phahameng tsa mocheso le khatello e phahameng, li-valve li hlokeha hore li be le litlhoko tse thata, eseng feela tse hlokang hore li be le ts'ebetso e ntle ea ho tiisa, empa hape li hloka hore li be le mocheso o phahameng le khatello ea khatello. E le valve e sebetsang ka mokhoa o phahameng oa indasteri, valve e nang le li-welded tse peli e 'nile ea sebelisoa haholo tšimong ea mocheso o phahameng le khatello e phahameng ka lebaka la moralo oa eona o ikhethang oa sebopeho le ts'ebetso e phahameng.
2. Litšobotsi tsa sebopeho sa li-valve tse nang le li-valve tse peli tse cheselitsoeng
2.1. Sebopeho se bonolo: The welded likotoana tse peli tsa bolo ea valve e entsoe haholo ka 'mele oa valve, bolo, setulo sa valve, kutu ea valve, selikalikoe sa ho tiisa le likarolo tse ling. E na le sebopeho se bonolo, boima bo bobebe, 'me ho bonolo ho kenya le ho hlokomela.
2.2. Ts'ebetso e ntle ea ho tiisa: Bolo le setulo sa valve li amohela ho tiisa sefahleho, ka sebaka se seholo sa ho tiisa le ts'ebetso e ntle ea ho tiisa, e ka finyellang litlhoko tsa ho tiisa tlas'a mocheso o phahameng le maemo a khatello e phahameng.
2.3. Lebelo le potlakileng la ho bula le ho koala: Valofo e cheselitsoeng ka likotoana tse peli tsa bolo e nka 90 ° ho potoloha ha bolo ho fihlela ho bula le ho koala, ka lebelo la ho bula le ho koala kapele le ts'ebetso e bonolo.
2.4. Ho hanyetsa phallo e nyane: Mocha oa bolo o entsoe ka bophara bo felletseng, ho hanyetsa phallo e nyane, matla a phallo e kholo, mme o ka fokotsa tšebeliso ea matla ea sistimi.
2.5. Mocheso o motle oa ho hanyetsa le khatello ea khatello: Valofo e entsoeng ka li-welded tse peli e entsoe ka thepa e khethehileng, e na le mocheso o babatsehang le ho hanyetsa khatello, 'me e loketse mocheso o phahameng le maemo a khatello e phahameng.
2.6. Mefuta e fapaneng ea ho khanna: tataiso, motlakase, pneumatic, hydraulic le mekhoa e meng ea ho khanna e ka khethoa ho latela litlhoko tsa 'nete.
3. Linyeoe tsa ts'ebeliso ea li-valve tse nang le li-valve tse peli tse cheselitsoeng mocheso o phahameng le maemo a khatello e phahameng
3.1. Indasteri ea peterole
Sebakeng sa ho hloekisoa sa khoebo ea petrochemical, mocheso o mahareng o phahame joalo ka 400 ℃ mme khatello e fihla ho 10MPa. Sesebediswa sena, belofo e cheselitsoeng ka likotoana tse peli tsa bolo e sebelisoa e le sesebelisoa sa bohlokoa ho laola phallo ea mokelikeli le khatello. Ka mor'a lilemo tse ngata tsa ts'ebetso, valve ea bolo e bontšitse ts'ebetso e ntle ea ho tiisa le mocheso le khatello ea khatello, ho netefatsa ts'ebetso e tsitsitseng ea sesebelisoa.
3.2. Indasteri ea matla
Sistimi ea metsi a fepelo ea boiler ea semela sa motlakase oa mocheso, mocheso o mahareng ke 320 ℃ mme khatello ke 25MPa. Tsamaisong ena, valve e nang le li-welded tse peli e sebelisoa e le sesebelisoa sa ho khaola le ho laola. Ts'ebetsong ea sebele, valve ea bolo e bontša litšobotsi tsa ho bula ka potlako le ho koala lebelo, ts'ebetso e ntle ea ho tiisa, le mocheso o babatsehang le ho hanyetsa khatello, ho fana ka tiiso e matla bakeng sa ts'ebetso e sireletsehileng le e tsitsitseng ea limela tsa matla a mocheso.
3.3. Indasteri ea metallurgic
Mocheng o chesang oa tlhahiso ea khoebo ea tšepe, mocheso o mahareng ke 600 ℃ 'me khatello ke 15MPa. Moleng ona oa tlhahiso, valve e cheselitsoeng ka likotoana tse peli e sebelisoa e le sesebelisoa sa taolo e mahareng. Valve ea bolo e bonts'a ts'ebetso e ntle tlas'a mocheso o phahameng le tikoloho ea khatello e phahameng, ho finyella litlhoko tsa tlhahiso ea mohala oa tlhahiso.
4. Litlhokomelo bakeng sa ts'ebeliso ea li-valve tse nang le likotoana tse peli tse cheselitsoeng mochesong o phahameng le maemo a khatello e phahameng.
4.1. Khetha lisebelisoa tse loketseng: Ho ea ka mocheso oa sebele oa ho sebetsa le khatello, khetha lisebelisoa tse nang le mocheso o motle haholo le ho hanyetsa khatello ho netefatsa bophelo ba tšebeletso ea valve ea bolo ka mocheso o phahameng le maemo a phahameng a khatello.
4.2. Moralo o tiileng oa ho tiisa: Moralo oa ho tiisa ke senotlolo sa li-valve tse nang le likotoana tse peli tsa bolo. Lisebelisoa tse loketseng tsa ho tiisa li lokela ho khethoa ho netefatsa ts'ebetso ea tiiso ea valve ea bolo ka mocheso o phahameng le maemo a khatello e phahameng.
4.3. Ntlafatsa mokhoa oa ho khanna: Ho latela litlhoko tsa 'nete, khetha mokhoa o nepahetseng oa ho khanna ho ntlafatsa ts'ebetso ea ts'ebetso le boits'oaro ba valve ea bolo.
4.4. Ho hlahlojoa le ho hlokomeloa kamehla: Tlas'a mocheso o phahameng le tikoloho ea khatello e phahameng, ts'ebetso ea ho tiisa le mocheso le khatello ea khatello ea valve ea bolo e ameha habonolo. Ka hona, valve ea bolo e lokela ho hlahlojoa le ho hlokomeloa kamehla ho netefatsa hore e sebetsa ka mokhoa o tloaelehileng.
4.5. Basebelisi ba literene: Matlafatsa koetliso ea basebetsi, ntlafatsa tsebo ea bona ea ho sebetsa, le ho fokotsa ho hlōleha ha valve ea bolo ho bakoang ke ts'ebetso e sa lokelang.
Valve e entsoeng ka likotoana tse peli e na le ts'ebetso e ntle ea ts'ebetso tlas'a mocheso o phahameng le tikoloho ea khatello e phahameng, e fana ka tiiso e matla bakeng sa peterole, lik'hemik'hale, matla a motlakase, metallurgy le liindasteri tse ling. Ts'ebetsong ea 'nete, lisebelisoa tse nepahetseng li lokela ho khethoa ho latela maemo a sebele a ho sebetsa, moralo o tiileng oa ho tiisa, mokhoa o ntlafalitsoeng oa ho khanna, tlhahlobo le tlhokomelo ea kamehla, le koetliso ea opareitara e lokela ho matlafatsoa ho netefatsa ts'ebetso e bolokehileng le e tsitsitseng ea valve ea bolo tlas'a mocheso o phahameng le o phahameng. tikoloho ea khatello. Ka tsoelo-pele e tsoelang pele ea theknoloji ea indasteri, valve e nang le li-welded tse peli e tla phetha karolo ea bohlokoa masimong a mangata.
