Ukusebenza kokutywinwa kwe-aenye ivalve yebhola yomanyano x9201-t emhlopheibhekisa kwisakhono sesivalo sevalvu ukuthintela ukuvuza okuphakathi, kwaye yeyona nto ibalulekileyo yesalathiso sobugcisa bevalve.Ukuvuza kwemidiya kunokubangela ilahleko yezinto, ungcoliseko lokusingqongileyo kunye neengozi.Kwimithombo yeendaba ezinokutsha, eziqhumayo, ezinetyhefu okanye ezine-radioactive, ukusebenza kokutywinwa kwevalve engavumelekanga ukuba ivuze kubhekiselele kwisakhono sesitywina sevalve ukuthintela ukuvuza kwemidiya, eyona nto ibalulekileyo isalathiso sobuchule bokusebenza kwesivalo.Ukuvuza kwemidiya kunokubangela ilahleko yezinto, ungcoliseko lokusingqongileyo kunye neengozi.Kwimidiya enokutsha, eqhumayo, eyityhefu okanye ene-radioactive, ukuvuza akuvumelekanga, ngoko ke ivalve kufuneka ibe nokusebenza okuthembekileyo kokutywinwa.
Itekhnoloji yokutywinwa kweValve yenze uphuhliso olukhulu ukusuka ekuzalweni kwayo ukuza kuthi ga ngoku.Ukuza kuthi ga ngoku, itekhnoloji yokutywina yevalve ifakwe ikakhulu kwimiba emibini, eyile, ukutywinwa okumileyo kunye nokutywinwa okuguquguqukayo.Ukutywinwa okungatshintshiyo Ukutywinwa okungatshintshiyo kubhekiselele ekwenziweni kwetywina phakathi kwamacandelo amabini angatshintshiyo.Eyona ndlela yokutywina kukusebenzisa iigaskets.Kukho iintlobo ezininzi zeegaskets, ezi zilandelayo zisetyenziswa ngokuqhelekileyo.
① Iwasha eflethi: iwasha esicaba phakathi kwamalungu amabini angatshintshiyo.Ngokubanzi zahlulwe zibe ziiwasha ezisicaba zeplastiki, iiwasha ezisicaba zerabha, iiwasha ezisicaba zesinyithi kunye neewasha ezisicaba ezihlanganisiweyo ngokwezixhobo ezisetyenzisiweyo.
②I-O-ring: iwasha ene-O-ring cross section.Ngenxa yokuba imilo yayo ye-cross-sectional i-O-shaped, inomphumela othile wokuziqinisa, ngoko ke umphumo wokutywina ungcono kune-gasket flat.
③ Iwasha: Iwasha esonga enye imathiriyeli kwenye imathiriyeli.Ezo gaskets ngokubanzi zine-elasticity entle kwaye zinokuphucula isiphumo sokutywinwa.
④ Iwasha enemilo eyodwa: iwasha enemilo engaqhelekanga.Kubandakanywa iiwasha ezimbhoxo, iiwasha zedayimani, iziwasha zegiya, iiwasha ezinamahova, njalo njalo.
⑤ Iiwasha zamaza: iiwasha zamaza.Olu hlobo lwe-gasket ludla ngokuqulunqwa ngezinto zetsimbi kunye nezinto ezingezona zetsimbi, kwaye zineempawu zamandla amancinci kunye nefuthe elihle lokutywinwa.
⑥ Umatshini wokuhlamba wokuqengqeleka: Ibhanti yentsimbi ebhityileyo kunye nebhanti engeyiyo eyentsimbi ziqhagamshelwe ngokusondeleyo ukwenza umatshini wokuhlamba.Le gasket ine-elasticity elungileyo kunye nokusebenza kakuhle kokutywinwa.Ukutywinwa okuguquguqukayo Ukutywinwa okuguquguqukayo luhlobo lwengxaki yokutywina ngexesha lentshukumo enxulumene nevalve.Ayivumeli ukuhamba okuphakathi ukuvuza kunye nokuhamba kwe-valve stem.Eyona ndlela yokutywina kukusebenzisa ibhokisi yokuhlohla.Kukho iindidi ezimbini ezisisiseko zokupakisha iibhokisi: uhlobo lwedlala kunye nohlobo lwentongomane yoxinzelelo.Uhlobo lwedlala ngoku lolona hlobo lusetyenziswa kakhulu.Ngokuqhelekileyo, i-gland inokwahlulwa ibe luhlobo oludibeneyo kunye nodidi oludibeneyo.Nangona ifom nganye yahlukile, ngokusisiseko iqulethe uxinzelelo lwebholithi.Iintlobo zamandongomane okucinezela zidla ngokusetyenziswa kwiivalvu ezincinci.Ngenxa yobukhulu bayo obuncinci, amandla oxinzelelo anqunyelwe.Kwibhokisi yokupakisha, ngenxa yokuba ukupakisha kuhambelana ngqo ne-valve stem, zonke iimfuno zokupakisha zitywinwa kakuhle, i-coefficient ephantsi ye-friction, iguquguqukayo kuxinzelelo kunye nobushushu be-medium, kunye nokumelana nokubola.Okwangoku, iifayili ezisetyenziswa ngokuqhelekileyo ziyi-rubber O-shaped
Umsesane, ukupakisha okuphothiweyo kwe-PTFE, ukupakisha kwe-asbestos kunye nokupakisha kweplastiki yokubumba.Uhlobo ngalunye lokupakisha lunemiqathango yalo esebenzayo kunye nobubanzi, obunokukhethwa ngokweemfuno ezithile.
