Ivhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhuvhu,iro rinonyanya kuita basa pakucheka pombi.
Theglobe valvendiyo vharuvhu inoshandiswa zvakanyanya, uye zvakare ndiyo yakanyatsokodzera fomu yekupuruzira.Nemhaka yekuti ine maitiro akanaka ekugadzirisa, uye kana ichienzaniswa nemamwe marudzi ekugadzirisa mavharuvhu, kuparadzirwa kwekupfeka kwakakomberedza chigaro chevharuvhu yekumira nekuda kwekukukurwa kunowedzera kufanana.
Ivhavhavha yeglobhu ivharuvhu yekumanikidza-kuvharisa.Naizvozvo, nzira yekusarudza nemazvo vharafu yevharuvhu inofanirwa kuisa kumanikidza kune yakafara flap kana yakavharwa, kuitira kuti pasave nekudonha kunoitika pakati penzvimbo mbiri dzekuvharira.Sezvo simba rekuisa chisimbiso revharuvhu yepasi uye kudzvanywa kwepakati kuri paaxis imwechete, uye nzira dzakapesana, simba rekuvhara haringogone kukwidziridzwa chete, asi rinokunda kudzvanywa kwepakati, saka simba rekusimbisa rinodiwa nepasirese. vharafu yevhavha yakakura kudarika iyo yevhavha yegedhi.
Kunyanya kukoshesa kunofanira kubhadharwa pakusarudzwa kwevhavha yeglobe.Ivharuvhu ine mhete yekuvharisa yakafuratira haigone kushandiswa kune tsvina midhiya kana midhiya ine zvimedu zvakasimba.Mune iyi svikiro, inonyanya kukodzera kushandisa tapered seal surface kuti uvhare.
Kazhinji, mavharuvhu akachekwa anokurudzirwa kupuruzira, kudzora, uye yakakwirira-kudzvanywa pombi masisitimu;mavharuvhu akachekwa anogona kusarudzirwa maviri-chinzvimbo kugadziridzwa, chiedza uye diki chimiro chinodiwa, hapana chakasimba chinodiwa pakureba kwechimiro, yakaderera kudzvanywa kucheka-kure (diki kudzvanywa musiyano), uye yakakwirira-tembiricha midhiya.;Mumatope, iyo yepakati ine zvimedu zvemuviri mumwechete, kupfeka kusagadzikana, shrinkage yedhayamita, chiito chekukurumidza (multi-turn kana kuvhura uye kuvhara), uye simba rekushanda rakaderera, edza kusasarudza valve yekumisa;kana ichida kuita chisimbiso chakanaka, kudzvanywa kwepamusoro-kubvisa (kuremerwa kwakasiyana)), ruzha rwakaderera, cavitation uye vaporization, diki diki rekudonha kumhepo, abrasive media, yakadzika tembiricha uye kutonhora kwakanyanya, unogona kushandisa yakakosha dhizaini. chimiro chevharuvhu yepasi .
Chimwe chinhu chakakosha chevharuvhu yeglobe ndechekuti chisimbiso chevharuvhu hunde inogona kutsiviwa nemvuto pachinzvimbo chekurongedza kuti iite bellows globe valve.Iyo bellows globe valve inokodzera kupisa, kuputika, muchetura, uye yakachena midhiya, uye inogona zvakare kusangana nezvinodiwa zvevacuum system.
Nekudaro, iyo globe valve inewo zvikanganiso zvayo, zvinonyanya kukonzerwa nemukati chimiro chemuviri wevharuvhu.Mugomba remuviri wevharuvhu, yepakati inoshanduka kubva pakuyerera yakatwasuka kuenda kumusoro kana kudzika yakatwasuka kuyerera, uyezve kuenda kune yakachinjika kuyerera, izvo zvinoguma nekurasikirwa kwekumanikidza, kunyanya mumagetsi emagetsi.Rudzi urwu rwekurasikirwa kwekumanikidzwa kunofanirwa kukwezva kutarisa kwakakwana.
