Umgaqo wokusebenza
Ivalve yebhola ephantsi yobushushu isetyenziswa ngokubanzi kwimeko apho ubushushu obuphakathi bungaphantsi kwe -40 ℃, kwaye i-valve flap ivulwa ngokuzenzekelayo kwaye ivalwe ngokuxhomekeke ekuhambeni kwe-medium ngokwayo, ukwenzela ukuba kuthintelwe i-medium ukuba ingabuyeli ngasemva.
Iimbonakalo
1. Isakhiwo sokuvula umngxuma wokunciphisa uxinzelelo kwi-core valve yamkelwa;
2. I-gasket yenziwe ngezinto zokuzalisa i-ceramic kunye nokutywinwa okuzinzileyo;
3. Umzimba wevalvu ulula kwaye uncinci ngobukhulu.Ukuze kuncitshiswe ilahleko yobushushu bomzimba wevalve, ngakumbi ukuqinisekisa ukusetyenziswa kwevalve phantsi kobushushu obuphantsi kakhulu, umzimba wevalve uyilelwe ngokukodwa ukuba ube nobunzima obuncinci kunye nobukhulu obuncinci;
4. Ivalve ene-axis ende inevalve apho ulwelo olunobushushu obuphantsi buhamba khona.Yamkela ifom ye-valve ende, enokuthi iphephe umphumo wokushisa kwangaphandle kwaye igcine i-gland kwiqondo lokushisa eliqhelekileyo ukukhusela ukusebenza kwesitywina sokuvala ukuba kuncitshiswe.Obu ubude bobona bude bufunyenwe ngokubala kunye nokulinga.
Iinzuzo zesicelo
1. Ukuxhathisa ulwelo kuncinci.Ivalve yebhola ineyona ndlela incinci yokuxhathisa ulwelo phakathi kwazo zonke iivalvu.Nkqu nevalve yebhola encitshisiweyo inokumelana nolwelo oluncinci;
2. Ukutshintsha kuyakhawuleza kwaye kulula.Ngethuba nje i-valve stem ijikeleza i-90 °, i-valve yebhola igqiba ukuvuleka okupheleleyo okanye isenzo sokuvala ngokupheleleyo, kwaye kulula ukuqonda ukuvulwa nokuvala ngokukhawuleza;
3. Ukusebenza kakuhle kokutywinwa.Umsesane wokutywina wesihlalo sevalve yebhola ngokuqhelekileyo zenziwe ngezinto ezi-elastic ezifana ne-polytetrafluoroethylene, ekulula ukuqinisekisa ukutywinwa, kunye nokunyanzeliswa kokutywinwa kwe-valve yebhola kwandisa ngokunyuka koxinzelelo oluphakathi;
4. Isitywina somthi sithembekile.Xa ivalve yebhola ivulwa kwaye ivaliwe, isiqu sevalve sijikeleza kuphela, ngoko ke ukupakisha kwesiqu sevalve akukho lula ukuba konakaliswe, kwaye amandla okutywina okutywinwa okubuyela umva kwesiqu sevalve ayanda ngokunyuka koxinzelelo oluphakathi. ;
5. Ukuvulwa kunye nokuvalwa kwe-valve yebhola ijikeleza kuphela i-90 °, ngoko kulula ukuqonda ukulawula ngokuzenzekelayo kunye nokulawula kude.Ivalve yebhola inokuxhotyiswa ngezixhobo ze-pneumatic, izixhobo zombane, izixhobo ze-hydraulic, izixhobo zokudibanisa i-gas-liquid okanye izixhobo zokudibanisa i-electro-hydraulic;
6. Ishaneli yevalve yebhola ithe tyaba kwaye igudile, kwaye akulula ukufaka indawo ephakathi, kwaye umbhobho unokugqithiswa ebholeni.
Isondlo
1. Khangela ukuba ngaba kukho umkhenkce kumzimba wevalve, ukuba kunjalo, nceda ususe nawuphi na umkhenkce kumzimba wevalvu, uze usebenzise ivalve;
2. Sebenzisa i-manual okanye i-pneumatic grease gun ukuze ugcwalise isisombululo sokucoca i-valve, kwaye usebenzise i-valve emva kwemizuzu eyi-10-20 ukukhupha i-sewage kwi-valve discharge nozzle;
3. Khangela ukupakishwa kwe-valve stem, i-flange ephakathi kunye nezinye iindawo zokuvuza;
4. Ukuba kukho ukuvuza kwisiqu sevalve, nceda ujonge ukuba ivalve inesakhiwo se-valve stem grease injection, ukuba kunjalo, ngokucothayo tofa igrisi yokutywina yevalve kwaye uyeke ukuzalisa;
5. Unyango lwangaphakathi lokuvuza kwe-valve yebhola yebhola ephantsi ihlanjululwe, kwaye isisombululo esiphambili ngumsebenzi.Ukongeza igrisi yokutywina yindlela encedisayo;
6. Xa i-valve ivalwe ngokupheleleyo, ukuhlolwa kokuvuza kwangaphakathi kunye nonyango lwe-valve yebhola yebhola ephantsi kufuneka iqhutywe ngokusemandleni;
Ukusebenza kwevalve ebandayo kufuneka ivule kwaye ivale ngokupheleleyo, kwaye ivalve engenakuvulwa kwaye ivalwe kufuneka ihanjiswe kangangoko kunokwenzeka.
