Li-valve tse bontšitsoeng setšoantšong ha li na khanyetso e tlaseli-valve tsa ho hlahloba tse sekamisitsoeng ka hamore ea boimae hlahisitsoe ke Jinbin Valve, ka boholo bo tlohang ho DN250 ho isa ho DN700. 'Mele oa valve o entsoe ka tšepe ea carbon ea WCB, o hlomelitsoe ka li-counterweights le li-cylinder tsa hydraulic, 'me o lekantsoe bakeng sa khatello ea ho sebetsa ea PN16, PN20 le PN25.

Valve ena ea mofuta oa silindara ea counterweight le hydraulic e thibelang butle e thibelang butle e sebelisa sebopeho sa mekhahlelo e 'meli sa ho bula le ho koala. Ha pompo ea metsi e ntse e sebetsa, khatello e mahareng e sutumelletsa disc ea serurubele ho buleha; counterweight e phahamisa hammoho le disc ho leka-lekanya boima ba poleiti ea serurubele, e fokotsa haholo khanyetso ea phallo ea metsi. Ho sa le joalo, medium e phallela ka har'a silindara ea hydraulic ho boloka khatello. Nakong ea ho koaloa ha pompo, tlas'a matla a kopaneng a boima ba 'mele, khatello e khahlanong le boima le khatello ea phallo e khutlelang morao, disc ea serurubele e koala ka potlako 80% ~ 90% ea tsela ea phallo ho thibela phallo e ngata ea morao. Ho otloa ha 10% ~ 20% e setseng ho koaloa butle ka ho damping ea silindara ea hydraulic. Valve ea nale e nolofalletsa ho lokisa ka nepo nako ea ho koala butle, e felisang matla a tšusumetso ea phallo e khutlelang morao mohato ka mohato 'me ka ho feletseng e thibela maqhubu a ho tšoha ha hammer ea metsi.

Melemo ea Kopo ea Motheo

1. Tlosa hamore ea metsi 'me u sireletse lisebelisoa

Ho kwala ka mekhahlelo ho fokolisa hamore ea metsi e nang le khatello e phahameng e hlahisoang ha pompo e koaloa, ho thibela ho phatloha ha phaephe le tšenyo ea ho khutlela morao ha pompo, 'me ho fokotsa litšenyehelo tsa tlhokomelo ea phaephe haholo.

2.Khanyetso ea phallo e tlase haholo bakeng sa ho boloka matla

Boima ba counterweight bo leka-lekanya boima ba poleiti ea serurubele bakeng sa phallo e bulehileng e sa sitisoeng. Tahlehelo ea hlooho ea eona e ka tlase ho feta 40% ho feta ea li-valve tsa ho hlahloba swing tse tloaelehileng, e fanang ka matla a nako e telele le poloko ea litšenyehelo.

3.Tshebetso ea ho tiisa e tšoarellang le e tšepahalang

E na le sebopeho sa ho kwala diski ya serurubele e nang le mebala e mmedi bakeng sa ho kwala ka thata. Mmele wa valve o manehilwe ka pente e thibelang ho bola ya epoxy, e loketseng metswako e mengata ho kenyeletswa metsi a hlwekileng, dikgwerekgwere le metsi a potolohang.

4. Phetoho e tenyetsehang e nang le ts'ebeliso e pharaletseng

Sistimi e ikemetseng ea ho damping ea hydraulic e lumella ho lokisoa ha nako ea ho koala butle ha ho hlokahala. E feta li-valve tsa ho hlahloba tse khutsitseng tse tletseng selemo ka moeli o moholo bakeng sa liteishene tsa pompo tse bophara bo boholo (DN300 le ho feta).

Li-valve tsa tlhahlobo tse tloaelehileng li koaloa ka botlalo hang-hang, e leng se bakang hamore e matla ea metsi habonolo. Tšusumetso e etsahalang khafetsa e khutsufatsa bophelo ba tšebeletso ea lipompo tsa metsi, liphaephe le li-flange. Mefuta e jereng ka selemo e sebetsa feela bakeng sa boholo ba liboto tse nyane, tse haelloang ke matla a ho sutumelletsa le a ho boloka mesamo bakeng sa bophara bo boholo.

Valve ena, e entsoeng ka mokhoa o ikhethileng bakeng sa lipompo tsa ho phunya, e kopanya mesebetsi e meraro: ho se khutlise, ho hatelloa ha hamore ea metsi le ho hanyetsa phallo e tlase. E nkela sebaka sa motsoako oa valve e tloaelehileng ea ho hlahloba hammoho le sesebelisoa sa buffer, e fokotsa li-fitting tsa liphaephe. ​​Litsamaisong tsa phallo e kholo joalo ka phepelo ea metsi ea masepala, metsi a potolohang a lifeme tsa motlakase, phepelo ea metsi le drainage ea lik'hemik'hale, le liteishene tsa lipompo tsa likhoerekhoere, e sireletsa polokeho ea ts'ebetso ea liphaephe ka botsitso, e atolosa bophelo ba ts'ebeletso ea sete ea lisebelisoa ka kakaretso, 'me e fana ka ts'ebetso e ntle ea litšenyehelo ts'ebetsong le tlhokomelong e felletseng.
