Ukusebenza kokuvalwa kwe-aI-valve yebhola lenyunyana eyodwa x9201-t emhlopheibhekisela ekhonweni lesivalo se-valve ukuvimbela ukuvuza okuphakathi, futhi iyinkomba yokusebenza kobuchwepheshe ebaluleke kakhulu yevalvu.Ukuvuza kwemidiya kungabangela ukulahleka kwempahla, ukungcoliswa kwemvelo ngisho nezingozi.Kwemithombo yezindaba evuthayo, eqhumayo, enobuthi noma ekhipha imisebe, ukusebenza kokuvala kwevalvu okungavunyelwe ukuvuza kubhekisela emandleni esivalo sevalvu ukuvimbela ukuvuza kwemidiya, okuyinkomba yokusebenza kobuchwepheshe ebaluleke kakhulu yevalvu.Ukuvuza kwemidiya kungabangela ukulahleka kwempahla, ukungcoliswa kwemvelo ngisho nezingozi.Ngemidiya evuthayo, eqhumayo, enobuthi noma enemisebe, ukuvuza akuvunyelwe, ngakho-ke i-valve kufanele ibe nokusebenza okuthembekile kokuvala.
Ubuchwepheshe bokuvalwa kwe-valve sebuthuthuke kakhulu kusukela ekuzalweni kwabo kuze kube manje.Kuze kube manje, ubuchwepheshe bokuvala ama-valve bufakwe ikakhulukazi ezicini ezimbili, okuwukuthi ukuvala uphawu okumile kanye nokuvala uphawu okuguquguqukayo.Ukuvalwa okungaguquki Ukuvalwa okungaguquki kubhekisela ekwakhekeni kophawu phakathi kwezingxenye ezimbili ezimile.Indlela eyinhloko yokuvala ukusebenzisa ama-gaskets.Kunezinhlobo eziningi zama-gaskets, ezilandelayo zivame ukusetshenziswa.
① Iwashi eliyisicaba: iwasha eyisicaba phakathi kwezingxenye ezimbili ezingashintshi.Ngokujwayelekile ihlukaniswe ngamawasha angamapulangwe ayipulastiki, amawasha ayisicaba erabha, amawasha ayinsimbi ayisicaba kanye namawasha ayinhlanganisela ayisicaba ngokuya ngezinto ezisetshenziswayo.
②I-O-ring: iwasha ene-O-ring cross section.Ngenxa yokuthi umumo wayo we-cross-sectional umise okwe-O, unomphumela othile wokuziqinisa, ngakho umphumela wokuvala ungcono kunowe-gasket eyisicaba.
③ Iwasha: Iwasha egoqa into eyodwa kwenye impahla.Ama-gasket anjalo ngokuvamile ane-elasticity enhle futhi angathuthukisa umphumela wokuvala.
④ Iwasha emise okukhethekile: iwasha enomumo ongajwayelekile.Kubandakanya amawasha okusaqanda, amawasha edayimane, amawasha egiya, amawasha amadovetail, njll. Lawa mawasha ngokuvamile anomphumela wokuziqinisa futhi asetshenziswa kakhulu kumavalvu omfutho ophezulu naphakathi nendawo.
⑤ Amawashi amaza: amawashi amaza.Lolu hlobo lwe-gasket luvame ukwakhiwa ngezinto zensimbi nezinto ezingezona ezensimbi, futhi lunezici zamandla amancane okucindezela kanye nomphumela omuhle wokuvala.
⑥ Umshini wokuwasha ogoqayo: Ibhande lensimbi elincanyana kanye nebhande elingelona elensimbi kuxhunywe eduze ukwenza umshini wokuwasha.Le gasket inokunwebeka okuhle nokusebenza kahle kokuvala.Ukuvala okunamandla Ukuvala uphawu okunamandla kuwuhlobo lwenkinga yokuvala ngesikhathi sokunyakaza okuhlobene kwevalvu.Ayivumeli ukugeleza okuphakathi ukuvuza ngokuhamba kwesiqu se-valve.Indlela eyinhloko yokuvala ukusebenzisa ibhokisi lokugxusha.Kunezinhlobo ezimbili eziyisisekelo zokugxusha amabhokisi: uhlobo lwendlala kanye nohlobo lwamantongomane okucindezela.Uhlobo lwegland okwamanje luyifomu elisetshenziswa kakhulu.Ngokuvamile, indlala ingahlukaniswa ibe uhlobo oluhlanganisiwe kanye nohlobo olubalulekile.Nakuba ifomu ngalinye lihlukile, ngokuyisisekelo liqukethe ukucindezela kwebhawodi.Izinhlobo zamantongomane okucindezela ngokuvamile zisetshenziselwa ama-valve amancane.Ngenxa yobukhulu bayo obuncane, amandla okucindezela alinganiselwe.Ebhokisini lokugxusha, ngenxa yokuthi ukupakisha kuthintana ngqo nesiqu se-valve, zonke izidingo zokupakisha ziwukubekwa uphawu okuhle, i-coefficient ephansi ye-friction, evumelana nezimo nokushisa kwe-medium, kanye nokumelana nokugqwala.Njengamanje, ama-filler asetshenziswa kakhulu anerabha emise okwe-O
Indandatho, ukupakisha okuboshwe nge-PTFE, ukupakisha kwe-asbestos kanye nokupakishwa kokubumba kwepulasitiki.Uhlobo ngalunye lokupakisha lunemibandela yalo esebenzayo kanye nobubanzi, olungakhethwa ngokwezidingo ezithile.
