Mndandanda wa Gulugufe

Chiyambi:

Valavu ya gulugufeKodi kuchokera ku banja la mavavu lotchedwamavuvu. Pogwiritsa ntchito, valavu imatsegulidwa kwathunthu kapena kutsekedwa pomwe disc imazungulira kotala. "Gulugufe" ndi disc dick yokhazikika pa ndodo. Valavu ikatsekedwa, disc imatembenuka kuti isadutseko m'njira. Valavu ikatsegulidwa kwathunthu, disc imazungulira kotala kuti iloketse gawo lopanda madzi. Valatiyo ikhoza kutsegulidwanso mosiyanasiyana kuti isayende bwino.

Pali mitundu yosiyanasiyana ya maamala a gulugufe, aliyense amazolowera zovuta zosiyanasiyana komanso kugwiritsa ntchito mosiyanasiyana. Valve wa zero-wozunzika wa zero, omwe amagwiritsa ntchito kusintha kwa mphira, ali ndi mawonekedwe otsika kwambiri. Valavu yamphamvu kwambiri ya Gulu Lalikulu, yomwe imagwiritsidwa ntchito panjira zapamwamba pang'ono, imayamba kulowa pakati pa mpando wa disse ndi chidindo cha thupi, ndi mzere wachigawo). Izi zimapangitsa kuti cam achitepo kanthu kuti akweze mpando kuchokera ku chisindikizo chochepa kwambiri kuposa momwe adapangira zojambula za zero zopangidwa ndipo amachepetsa chizolowezi chake chovala. Valavu yabwinobwino kwambiri pazinthu zapamwamba kwambiri ndi gulu lankhondo lachitatu lankhondo. Mu valavu iyi yolumikizira mpandowo imatha, yomwe imagwira poyerekeza ndi disc ndi mpando. Pankhani ya maulendo atatu ovulala pampando amapangidwa ndi chitsulo kuti ithe kupangidwa motero kuti ikwaniritse kuwira pang'ono polumikizana ndi disc.

Mitundu

1. Ma Varric Gulugufe- Mtundu uwu wa valavu imakhala ndi mpando wa mphira wolimba wokhala ndi disc.
2. Ma Valovely-Eccentric Gulugufe(Mavalidwe apamwamba a gulugufe kapena mavalo a gulugufe awiri) - mtundu wina wa zinthu zomwe zimagwiritsidwa ntchito pampando ndi disc.
3. Ma Valove Altly-Eccentric Gulugufe(mavalo a gulugufe otakasuka) - mipando yake imakhazikika kapena kapangidwe ka mipando yolimba yazitsulo.

Mavalo a Wafe Arth

AWalwerfflyyapangidwa kuti isunge chisindikizo chotsutsana ndi kupanikizika kwa bi-njira kuti mupewe njira iliyonse yomwe idapangidwira kuti atuluke. Zimakwaniritsa izi ndi chisindikizo choyenera chokwanira; Ie, gasket, o-mphete, molondola makina, ndipo valavu yathyathyathya kumtunda ndi pansi.

Lug-forth Waller valavu

Mavavu a Lugtakhala ndi zopindika mbali zonse za thupi la valavu. Izi zimawathandiza kuti aikidwe mu kachitidwe kaziwiri pogwiritsa ntchito ma bolo awiri a ma bolts ndipo palibe mtedza. Valavuyo imayikidwa pakati pa ma flanges awiri pogwiritsa ntchito ma balts osiyana siyana. Zokhazikitsa izi zimaloleza mbali ya masipu kuti isasunthidwe popanda kusokoneza mbali inayo.

Nyengo ya Lug-Choyimira Gulu Logwiritsa Ntchito Mu Ntchito Yakufa Yamuyaya nthawi zambiri imakhala ndi njira yochepetsera. Mwachitsanzo, valavu ya gulugufe wambiri yomwe ili ndi ma flanges awiri ali ndi ma ppa 1,000. Valavu yomweyo idakwezedwa ndi utoto umodzi, mu ntchito yakufa, ili ndi mtundu wa 520 wa ppa (75 wa ppi). Ma Vanive Optleck amalephera kugwiritsa ntchito mankhwala ndi ma sol sol sol ndipo amatha kuthana ndi kutentha mpaka 200 ° C, komwe kumapangitsa kuti ikhale yankho losinthasintha.

Gwiritsani ntchito makampani

Mu mankhwala opangira mankhwala, mankhwala, ndi mafakitale azakudya, valavu ya gulugufe imagwiritsidwa ntchito posokoneza maluwa (cholimba, madzi, mpweya) munjira. Mavavu omwe amagwiritsidwa ntchito mu mafakitalewa amapangidwa molingana ndi malangizo a CGMP (omwe ali bwino). Mavalo a gulugufe m'malo mwake amasintha ma valve a mpira, makamaka petroleum, chifukwa chotsika mtengo komanso kusakaniza kuyikapo, koma mapaipi okhala ndi ma ngulufeserffly sangathe kuyeretsa.
