Ivalve yesihlalo sentsimbi ikhethwe kwindawo enzima enje ngamasuntswana aqinileyo, abrasive, ubushushu obuphezulu okanye udidi loxinzelelo oluphezulu okanye nabani na okwimeko ekhankanyiweyo edityanisiweyo, umbhobho oqhelekileyo onjengekhemikhali yamalahle, ipulp & nephepha kunye nendawo yokucoca ioyile ekrwada njl.njl. Ivalve yesihlalo sentsimbi ibonisa ukusebenza kakuhle kokutywinwa, inkonzo yexesha elide, i-torque ephantsi kunye nelahleko yoxinzelelo oluncinci ngokuthelekisa kwinkonzo ekhankanywe ngasentla.Ivalve jikelele njengeglowubhu kunye nevalve yesango ayikwazanga ukumelana nemeko enjalo yokusebenza, ngoko ke ivalve yesihlalo sentsimbi ikhula ngakumbi kwiimfuno zenkonzo eqatha.
- I-ARAN ephezulu yentsimbi ehleli ivelufa yebhola ifaka itywina yentsimbi ukuya kwintsimbi phakathi kwezihlalo kunye nebhola yendibano yevalve.
- ● Ngokwemeko yokusebenza eyahlukileyo, i-QL isebenzise ibhola ephucukileyo kunye nesihlalo sobuchule bokugquma ubulukhuni, umgangatho oqhelekileyo uya kuba ngaphezu kwe-HRC 60, kwaye ubuninzi buya kuba ngaphezu kwe-HRC 74. I-STL6, i-Ni 60, i-STL egqunyiweyo, njl njl.
- ● I-HVOF ekhethwayo (isantya esiphezulu se-oxygen-fuel) ubuchule bokugquma imathiriyeli chromium carbide CRC, tungsten carbide TCC/Cr3C2, istellite hard ejongene neNi60 enobulukhuni 68-74 HRC kunye nokwaleka 02-0.25mm.I-nickel-based alloy thermal spray welding technology iteknoloji yokwaleka ngokubanzi imalunga ne-0.5 ~ 1.0mm, ukuqina kunokufikelela kwi-HRC55 ~ 65, kwaye amandla okubopha malunga ne-400MPa.Ezi zinto zinobushushu obuphezulu kunye nobunzima boxinzelelo oluphezulu, ukubola kunye nokumelana nobude.

- ● Ivalve yentsimbi yokutywina isitulo sebhola ifuna umatshini ogqwesileyo kunye nokusila ibhola ukuze kuqinisekiswe ukutywinwa okuqinisekileyo kovavanyo lokuvuza kweqamza eliqinile.
- ● I-Butterfly spring okanye i-spring elayishiwe uyilo kuyilo lokutywinwa kwesitulo susa ivalve yebhola exinaniswa kubushushu obuphezulu.
- ● Ivalve yebhola edadayo yesihlalo sentsimbi inesakhiwo sokutywina emva kwesiphelo sokungena kwebhola, kwaye sitywina esiyindlela enye enecala lokuhamba likumzimba wevalvu.Ukuba abathengi baneemfuno ezikhethekileyo, isakhiwo sokutywinwa kwendlela ezimbini sinokuveliswa.
- ● Ivalve yesihlalo sebhola yentsimbi enyuswe ngetrunnion iqhele ukuba nesakhiwo sokutywina isihlalo ekupheleni kwendawo yokungena yebhola.Izihlalo ezibini zinokuzinqumla ngokuzimeleyo i-medium kwi-inlet kunye ne-outlet ekupheleni ukufezekisa umsebenzi webhloko kabini.Xa ivalve yebhola ivaliwe, nokuba zombini iziphelo zokungena kunye nokuphuma kwevalve zixinzelelwe ngaxeshanye, umgodi ophakathi wevalve kunye neepaseji kuzo zombini iziphelo zinokuvaleka ukusuka komnye nomnye, kwaye okuphakathi okuseleyo ngaphakathi. umngxuma ophakathi unokukhutshwa ngeevalvu zokukhulula.
- Ibhola NDE khangela, ukuchaneka CNC ibhola machining & ukugaya
- Ukugqitywa kweBhola ngaphezulu kwe-Ra 0.2, Ukujikeleza kweBhola kungaphantsi kwe-0.02mm
- ● Ubushushu obuphantsi bohlobo lwentsimbi yesitulo ivalve yesihlalo, ubushushu obuphakathi bufikelela -196 ℃, umzimba wevalve kunye namalungu angaphakathi aphathwa ngu-196 design degree ulwelo lwenitrogen yobushushu obuphantsi konyango lwe-cryogenic, kunye nevalve yokwandisa i-stem bonnet ukuqinisekisa ukuba ivalve isetyenziswa. kwinkonzo yobushushu obuphantsi kakhulu, izinga lokuvuza kwevalvu ngu-zero.
- ● Uhlobo lobushushu obuphezulu, ubushushu obuphakathi buphezulu njenge-540 ℃, i-valve yomzimba kunye namalungu angaphakathi enziwe ngentsimbi ye-alloy ekhethekileyo yokumelana nobushushu emva konyango olukhethekileyo, kwaye i-valve stem iyandiswa kunye ne-bellow yokuchitha ubushushu ukuqinisekisa ukusetyenziswa okuqhelekileyo kwiindawo eziphezulu. inkonzo yobushushu, kunye nokusebenza kwevalve kukuvuza kwe-zero.
- I-ARAN yentsimbi ehleli iivalvu zeBhola yentsimbi isetyenziswa ikakhulu kwiimeko zenkonzo eziqatha ezinjengomhlwa ophezulu kunye nolwelo lwenkqubo yokhukuliseko olunamasuntswana aqinileyo namaqondo obushushu aphezulu okanye uxinzelelo oluphezulu, iimeko ezinjalo ivalve yebhola ethambileyo ehleliyo ayinako ukuqina ngenxa yomahluko wezinto zokuhlala.Ngesicelo sombuzo, ulwazi lwevalvu ephakathi kunye nobushushu bubaluleke kakhulu kwi-QL injineli yokuthengisa ukukhetha uhlobo oluchanekileyo lwemodeli.
