Nezvekuumbwa kweplate yeshavishavi yevharuvhu yeshavishavi hombe-dhayamita, AWWA C504 (American Water Supply Engineering Association Standard) inotaura kuti ndiro yeshavishavi haifaniri kuva nembabvu dzakachinjika, uye ukobvu hwayo hahufanire kunge hwakakura kudarika 2.25 times the diameter of the butterfly plate vharafu hunde.
Mvura inopinda mukati uye mvura-kunze kwepureti ye butterfly inofanira kugadziriswa.
Zvisungo zvemukati hazvigone kubuda kunze kweplate ye butterfly, kuitira kuti usawedzera nzvimbo yakatarisana nemvura.
2.2 Rubber chisimbiso
Mvura inopinda mukati uye mvura-kunze kwepureti ye butterfly inofanira kugadziriswa.

2.2 Rubber chisimbiso
Dzimwe nguva hupenyu hwebasa rerubha butterfly valve ipfupi, iyo inobatana nemhando yerubha uye hupamhi hwechisimbiso chepamusoro.Mhete yekuisa chisimbiso yerubha-yakavharwa butterfly valve inofanira kugadzirwa yemhando yepamusoro yerubha zvinhu, uye iyo nzira yemitemo inofanirwa kuteverwa panguva yekumanikidza kuumbwa.Iyo tembiricha yevulcanization haifanirwe kuwedzererwa, uye nguva inogona kupfupikiswa, zvikasadaro zvinokonzeresa kuti mhete yekuisa chisimbiso ichembera uye iparare.Iyo yesimbi yekuisa chisimbiso pamusoro inofananidzwa nerubha sealing ring inofanira kuva nehupamhi hwakakwana, kana zvisina kudaro rubber sealing ring haisi nyore kuiswa.Mukuwedzera, chimiro uye kushivirira kwechinzvimbo, symmetry, kunyatsojeka, kutsvedzerera, uye elasticity yemhete yekuisa chisimbiso chevhavhavha uye bhodhoro ndiro zvinokanganisawo hupenyu hwebasa rerubha chisimbiso mhete.
2.2 Kuomarara
Kuoma inyaya inokosha mukugadzirwa kwevhavhavhavhavha, iyo yakabatana nezvinhu zvakadai semapuleti e butterfly, shafts yevhavha uye zvibatanidza.
Kuoma inyaya inokosha mukugadzirwa kwevhavhavhavhavha, iyo yakabatana nezvinhu zvakadai semapuleti e butterfly, shafts yevhavha uye zvibatanidza.
(1) Saizi yevhavha shaft Saizi yevhavha inotsanangurwa muAWWA C504.Kana saizi yevhavha shaft isingaenderane nezvinodiwa, panogona kunge pasina kusimba kwakakwana, reverse seal leakage, uye hombe yekuvhura torque.Kuoma kweshaft kwakabatana ne1 / EI, kureva kuti, kuvandudza kuoma uye kuderedza dambudziko rekugadzirisa, tinofanira kutanga nekuwedzera EI.E ndiyo modulus ye elasticity.Kazhinji, kusiyana kwesimbi hakusi kukuru, uye zvinhu zvakasarudzwa hazvina simba pakuoma.Ini inguva ye inertia uye ine hukama nehukuru hwechikamu che shaft.Saizi yevhavha shaft inowanzoverengerwa zvichienderana nekubatanidzwa kwekukotama uye torsion.Izvo hazvisi chete zvine hukama ne torque, asi zvakare zvinonyanya hukama neiyo nguva yekukotama.Kunyanya, nguva yekukotama yevharuvhu yakakura-dhayamita yakakura kupfuura torque.
(2) Shaft hole coordination Shanduro yekare yeAWWA C504 inotaura kuti shaft yevharuvhu yevharuvhu ndeye shaft yakatwasuka.Mushure meiyo 1980 vhezheni, yakatsanangurwa kuti yaigona kuitwa kuita maviri mapfupi shaft.Zvinoenderana neAWWA C504 uye GB12238, kureba kwakamisikidzwa kweshaft uye gomba kunofanirwa kuve 1.5d.Iyo gap (C kukosha) pakati pemucheto wemuviri wevharuvhu uye kuguma kwekutsigira kwebhoti butterfly mune axial dimension yeJapan butterfly valve inotsanangurwa, iyo inowanzoenderana nehukuru hwedhayamita, iri pakati pe25 ne45mm. , iyo yekudzikisa chinhambwe pakati pechitsigiro cheshaft (C kukosha), nekudaro kuderedza nguva yekukotama uye deformation ye shaft.
(3) Butterfly plate structure Chimiro chebhoti yebhoti ine hukama hwakananga nekuoma, saka kunze kwechimiro cheplate flat, inowanzoitwa muhari yehari kana truss shape.Muchidimbu, ndeyekuwedzera nguva ye inertia yechikamu kuti uwedzere kuoma.
(4) Chimiro chemuviri wevhavha Panewo matambudziko ekuoma mukugadzirwa kweguru-diameter butterfly valve body.Kazhinji, kune mbabvu dzemhete uye mbabvu dzemuchinjikwa.Kutaura zvazviri, mbabvu dzemuchinjikwa dzinongowedzera kugadzikana uye hazvifaniri kunge zvakanyanyisa.Iwo makuru ndiwo mbabvu dzemhete.Kana iwe uchikwanisa kuwedzera ∩-yakaita mbabvu, zvichave zvakanyanya kubatsira kune kuomarara, asi pane dambudziko rekushomeka kwekugadzira.
2.3 Mabhengi ekuzvizora
Yakawanda kana yese yepakati yekumanikidza pane butterfly ndiro (reverse) inopfuudzwa kune inotakura kuburikidza neshaft, saka kutakura kunoita basa rakakosha.Mamwe mavharuvhu eshavishavi ekunze akareruka uye anoshanda, uye mavharuvhu madiki-caliber anogona kushandurwa nemunwe mumwe, nepo mamwe mavharuvhu emumba anorema.Pamusoro peiyo coaxiality, symmetry, kurongeka kwekugadzirisa, kupedzisa uye kunaka kwekurongedza, zvakanyanya Chinhu chakakosha ndiko lubricity yechinhu che sleeve.Iyo AWWA C504 yakajairwa inokurudzira kuti shaft sleeve kana kutakura yakaiswa mumuviri wevharuvhu kunofanirwa kunge kuri kuzvigadzika zvinhu, uye shaft sleeve ine dambudziko rekudzikisa friction uye lubrication, uye ngura haibvumidzwe.Pasina shaft sleeve, kunyange kana shaft yevhavha iri simbi isina tsvina, muviri wevhavha une ngura uye matambudziko ekunamatira.Kushandiswa kwebushings kunogonawo kuwedzera kuoma.
