Isikhokelo seZitulo zeValve yeBhola: Isixhobo esiyimfihlo seSeal yakho

Isikhokelo seSihlalo seValve yeBhola: Imisebenzi, Izixhobo (iSihlalo sePTFE kunye nokunye) kunye noHlobo lobushushu | I-Ultimate Seal

Kwihlabathi leiivalvu zebhola, ukutywina okusebenzayo kubaluleke kakhulu. Eyona nto iphambili kulo msebenzi ubalulekileyo kukukho icandelo eliphambili:Isihlalo seValve yeBhola, idla ngokubizwa ngokuba yiIsihlalo seValveEli qhawe lingadunyiswanga lilo "qhawe lokwenene lokutywina" kwindibano yeBall Valve.

Yintoni kanye kanye iSihlalo seValve yeBhola

IIsihlalo seValve yeBholayinto ebalulekileyo yokutywina ngaphakathiivalvu yebholaisakhiwo. Ngokwesiqhelo yenziwe ngesinyithi okanye ngezinto ezingezizo zesinyithi, ifakwe ngaphakathi komzimba wevalvu. Indima yayo ephambili kukwenza ujongano oluqinileyo lokutywina ngebhola ejikelezayo. Ngokugcina olu nxibelelwano lusondeleyo,Isihlalo seValveivumela ivalvu ukuba ivale okanye ilawule ukuhamba kolwelo ngokuthembekileyo.

Ingozi Ezintathu Zesihlalo SeValve: Ngaphezulu Kokutywina Nje

YanamhlanjeIzihlalo zeValve yeBholazinezakhono ezimangalisayo ngaphaya kokutywinwa okusisiseko:

1. Ukutywina okuZilungelelanisayo (I-Shape-Shifter):Njengomqamelo we-memory foam ohambelana nentloko yakho, i-Valve Seat esemgangathweni ophezulu igcina ukuthamba kwayo kumanqanaba obushushu obugqithisileyo (ngokubhekiselele kwimigangatho ye-ASTM D1710, eqhelekileyo -196°C ukuya ku-+260°C). Oku kuthamba kwayo kuyivumela ukuba ihlawule ngokuzenzekelayo ukuguguleka okuncinci kumphezulu webhola, ukuqinisekisa ukuthembeka kokutywinwa kwexesha elide.

2. UMlawuli woLwelo (uMthinteli):Uyilo oluyilwe ngokukodwa, olufana ne-V-port Ball Valve Seats, lukhokela ngokukhutheleyo i-medium egelezayo. Olu hambo oluqondisiweyo lunceda ekukhangeleni iindawo zokutywina, luthintele ukuqokelelana kwenkunkuma okanye izinto ezincinci ezinokubangela umonakalo kwi-seal.

3. Ummeli weNgxakeko (Ukhuseleko loMlilo):Uyilo oluthile lweSihlalo seValve luneempawu ezikhuselekileyo emlilweni. Kwimeko yobushushu obugqithisileyo (njengomlilo), ezi zihlalo zenzelwe ukutsha okanye ukwenza i-carbonize. Olu maleko lwenziwe nge-carbonize emva koko lwenza uphawu lwesibini, olungxamisekileyo lwentsimbi ukuya kwisinyithi, oluthintela ukungaphumeleli okukhulu.

Isayensi Yokutywina: Indlela Isihlalo SeValve Esisebenza Ngayo

Ukutywina kwenzeka ngokucinezela ngqo ngokomzimba. Xa ibhola ijikeleza iye kwindawo evaliweyo, icinezela ngokuqinileyo nxamnyeIsihlalo seValve yeBholaOlu xinzelelo lutshintsha kancinci izinto zesihlalo, nto leyo eyenza umqobo oqinileyo nxamnye nombane. Iivalvu zebhola eziqhelekileyo zisebenzisa izihlalo ezimbini zeValve - esinye sikwindawo yokungena kunye nesinye kwicala lokuphuma. Kwimeko yokuvalwa, ezi zihlalo "ziyayibamba" ibhola ngokufanelekileyo, zikwazi ukumelana noxinzelelo olufikelela kwi-16MPa (ngeImigangatho ye-API 6DUyilo oluphuculweyo, olufana nezihlalo ze-V-port, lunokuphucula ngakumbi ukutywinwa ngokusebenzisa amandla okusika alawulwayo asebenza kwimidiya.

Ububanzi bobushushu beSihlalo seValve yeBhola: Izinto eziphathekayo

Imida yobushushu bokusebenza kwe-Isihlalo seValve yeBholazilawulwa ngokusisiseko bubume bezinto ezisetyenzisiweyo. Nantsi inkcazelo eneenkcukacha ngezixhobo zesihlalo esiqhelekileyo kunye nobude bobushushu bazo obubalulekileyo:

Ingqwalasela ebalulekileyo:Izixhobo ezidweliswe apha ngasentla zimele ukhetho oluqhelekileyo.Isihlalo seValve yeBholaukhetho kufuneka lusekelwe kwiiimeko ezithile zokusebenza(ubushushu, uxinzelelo, isantya esiphakathi, umjikelo, njl.njl.) wesicelo ngasinye. Kukho ezinye izinto ezikhethekileyo ezininzi ukuhlangabezana neemfuno ezizodwa ngaphaya kobushushu nje kuphela. Soloko unxibelelana nabavelisi beevalvu ukuze ufumane iingcebiso ezichanekileyo zezinto ezilungiselelwe inkqubo yakho. IlungeloIsihlalo seValvekubalulekile ukubaivalvu yebholaukusebenza kunye nobude bexesha.
