Tsananguro yakazara uye ruzivo rwekutsanangura magedhi mavharuvhu

1.Tsanangudzo yevhavha yegedhi Imhando yevhavha iyo inoshandiswa zvakanyanya mupombi. Inonyanya kutamba basa rekubatanidza nekucheka pakati. Haina kukodzera kudzora kuyerera kwepakati, asi inogona kutonga kuyerera zvichienderana nekukwira nekudonha kwedzinde (semuenzaniso moto-kurwisa elastic chigaro chegedhi vharafu ine kuvhura uye kuvhara chiyero). Kuenzaniswa nemamwe mavharuvhu, mavharuvhu egedhi ane huwandu hwakasiyana hwekushandiswa kwekumanikidza, tembiricha, caliber uye zvimwe zvinodiwa. 2. Gate Valve Structure Gedhi mavharuvhu anogona kukamurwa kuva wedge mhando, imwe gedhi mhando, elastic gedhi mhando, kaviri gedhi mhando uye parallel gedhi mhando maererano yavo mukati maumbirwo. Zvinoenderana nemusiyano wetsigiro yetsinde, inogona kukamurwa kuita yakavhurika stem gedhi vharafu uye yakasviba stem gedhi vharafu. 3. Muviri wevharuvhu uye mumhanyi Chimiro chemuviri wevharuvhu wegedhi chinotarisa kubatana pakati pemuviri wevharuvhu nepombi, muviri wevharuvhu uye chivharo chevharuvhu. Panyaya yenzira dzekugadzira, kune kukanda, kuforoma, kuforoma, kukanda uye kupinza, uye pombi plate welding. Muviri wevharuvhu wekugadzira wakakura kuita hombe, ukuwo muviri wekukanda vharafu wakakura zvishoma nezvishoma kuita diki caliber. Chero mhando yemuviri wevharuvhu wegedhi unogona kugadzirwa kana kukandwa, zvichienderana nezvinodiwa nemushandisi uye nzira yekugadzira ndeyemugadziri. Nzira yekuyerera yegedhi revhavha yemuviri inogona kukamurwa kuita marudzi maviri: yakazara-dhayamita mhando uye yakaderedzwa-dhayamita mhando. Iyo dhayamita yezita rekuyerera inongofanana nedhayamita yezita revharuvhu, uye dhayamita diki yenzira yekuyerera kupfuura dhayamita yezita revharuvhu inonzi yakaderera dhayamita rudzi. Kune marudzi maviri ezvimiro zve shrinkage: yunifomu shrinkage uye shrinkage yakafanana. Iyo tapered chiteshi ndeye isiri-uniform dhayamita kuderedza. The aperture of the inlet end of this type of valve is basically yakafanana nedhayamita yezita, uyezve zvishoma nezvishoma inoderedza kusvika padiki pachigaro. Zvakanakira kushandisa shrinkage runner (ingave conical chubhu isiri-uniform shrinkage kana yunifomu shrinkage) yakaenzana saizi yevharuvhu, iyo inogona kuderedza saizi yegedhi, kuvhura uye kuvhara simba uye nguva. Izvo zvisingabatsiri ndezvekuti kuyerera kwekudzivirira kunowedzera, kudonha kwesimba uye kushandiswa kwesimba kunowedzera, saka shrinkage gomba harifanire kunge rakakura. Kune tapered chubhu dhayamita kuderedzwa, chiyero chemukati dhayamita yechigaro kusvika kune zita rekuti dhayamita kazhinji 0.8-0.95. Mavharuvhu ekudzikisa ane dhayamita yezita asingasviki 250mm kazhinji ane chigaro chemukati dhayamita rimwe giya rakaderera pane dhayamita yezita; Mavharuvhu ekudzikisa ane dhayamita yezita akaenzana kana kupfuura 300 mm kazhinji ane chigaro chemukati dhayamita magiya maviri akaderera pane dhayamita yezita. 4. Kufamba kwemavharuvhu egedhi Kana gedhi revhavha richivhara, nzvimbo yekuvhara inogona kuvharwa chete nepakati pekumanikidza, kureva, chete nepakati pekumanikidza kudzvanya chisimbiso chepamusoro chegedhi kune chigaro kune rumwe rutivi. chengetedza nzvimbo yekuisa chisimbiso, iyo inozvisimbisa. Mazhinji mavharuvhu emagedhi anomanikidzwa kuvhara, ndiko kuti, kana vharuvhu ichivhara, gedhi rinofanira kumanikidzwa pachigaro nechisimba chekunze kuti ive nechokwadi chekuisa chisimbiso. Motion mode: Gedhi regedhi vharafu rinofamba mumutsara wakatwasuka nedzinde, inozivikanwawo seyakavhurika bar gedhi vharafu. Kazhinji pane trapezoidal tambo padanda rekusimudza. Kuburikidza nenati iri pamusoro pevharuvhu uye girovha yegirovha pamutumbi wevharuvhu, iyo inotenderera inofamba inoshandurwa kuita mutsara wekufamba, kureva kuti, torque yekushandisa inoshandurwa kuita yekusundira kwekushanda. Paunenge uchivhura valve, apo gedhi rinosimudza kukwirira kwakaenzana ne1: 1 nguva yevhavhavhavha, nzira yekuyerera yakazaruka zvachose, asi kana ichimhanya, nzvimbo iyi haigoni kuongororwa. Mukushandiswa kunoshanda, iyo vertex yevhavha stem inoshandiswa sechiratidzo, ndiko kuti, nzvimbo yevhavha tsinde isingafambi inoshandiswa senzvimbo yayo yakazara yakazaruka. Kuti utarise chiitiko chekuvhara chekuchinja kwekushisa, vharafu inowanzovhurwa kune vertex chinzvimbo uye inodzoserwa kune 1/2-1 kutendeuka senzvimbo yevhavha yakazaruka zvizere. Nokudaro, nzvimbo yakazara yakazaruka yevhavha inotarirwa nenzvimbo yegedhi (kureva sitiroko). Mamwe magedhi evharuvhu stem nzungu akaiswa pagedhi ndiro. Handwheel rotation inoita kuti dzinde ritenderere, izvo zvinosimudza ndiro yegedhi. Iri rudzi rwevharuvhu inonzi rotary stem gedhi vharafu kana rima stem gedhi vharafu. 5. Mabhenefiti ekuita kwegedhi mavharuvhu 1. Valve fluid kupikisa idiki, nekuti gedhi revhavha muviri wakatwasuka-kuburikidza, kuyerera kwepakati hakuchinji nzira, saka kuyerera kunopesana kudiki pane mamwe mavharuvhu; 2. Kuita chisimbiso kuri nani pane vharuvhu yeglobhu, uye kuvhura nekuvhara kunoponesa vashandi kupfuura vharuvhu yeglobhu. 3. Yakasiyana-siyana yekushandiswa, kuwedzera kune steam, mafuta uye mamwe midhiya, asiwo yakakodzera kune yepakati ine granular solids uye yakakwirira viscosity, yakakodzerawo kushandiswa sevhavha yemhepo uye yakaderera vacuum system mavharuvhu; 4. Gedhi vharafu ivharuvhu ine kaviri kuyerera kutungamira, iyo isingaganhurirwe nekuyerera kwepakati. Naizvozvo, vharafu yegedhi inokodzera mapaipi apo yepakati inogona kushandura mafambiro ekuyerera, uye zvakare iri nyore kuisa. 6. Kukanganisa kwekushanda kwegedhi revhavha 1. High design dimension uye nguva yakareba yekutanga nekuvhara. Pakuvhura, zvinodikanwa kusimudza ndiro yevhavha kusvika kumusoro kwekamuri yevhavha, uye kana ichivhara, zvakakosha kudonhedzera mahwendefa ose evhavha muchigaro chevhavha, saka kuvhura uye kuvhara kwevhavha yevhavha yakakura. uye nguva yakareba. 2. Nekuda kwekukakavadzana pakati penzvimbo mbiri dzekuisa chisimbiso cheplate yevharuvhu uye chigaro chevharuvhu pakuvhura nekuvhara, nzvimbo yekuisa chisimbiso iri nyore kukwenya, iyo ine simba pakuita chisimbiso uye hupenyu hwebasa, uye hazvisi nyore. kuchengetedza. 7. Kuenzanisa kwekushanda kwemavhavha emagedhi ane maitiro akasiyana-siyana 1. Wedge type single gedhi valve A. Chimiro chiri nyore kudarika elastic gedhi valve. B. Pakupisa kwepamusoro, kushanda kwechisimbiso hakuna kunaka seye elastic gate valve kana double gedhi valve. C. Inokodzera kupisa kwepamusoro-soro zviri nyore kukoka. 2. Elastic gedhi vharuvhu A. Imhando yakakosha yewedge type single gedhi vharafu. Kuenzaniswa ne wedge gedhi vharafu, kuita chisimbiso kuri nani pakupisa kwakanyanya, uye gedhi harisi nyore kuvharwa mushure mekupisa. B. Inokodzera kupfutidza, tembiricha yemafuta zvigadzirwa neoiri uye gasi media, uye yekugara ichichinja zvikamu. C. Haikodzeri nyore kubika svikiro. 3. Mavharuvhu egedhi regedhi A. Kuisa chisimbiso kuri nani pane wedge gedhi vharafu. Kana iyo yekuyerereka yekona yekuisa chisimbiso pamusoro uye chigaro chakakodzera isina kunyatso kurongeka, ichine yakanaka yekuisa chisimbiso kuita. B. Mushure mekuvharwa kwechisimbiso chegedhi chasakara, simbi yesimbi iri pasi pepamusoro pepamusoro pe spherical surface inogona kuchinjwa uye kushandiswa pasina kutarisa uye kugaya nzvimbo yekuvhara. C. Inokodzera kupfutidza, tembiricha yemafuta zvigadzirwa nemafuta uye gasi media, uye yekugara ichichinja zvikamu. D. Haikodzeri nyore kubika svikiro. 4. Parallel gedhi mavharuvhu A. Kuisa chisimbiso kuita kwakaipisisa kupfuura mamwe mavharuvhu gedhi. B. Inokodzera zvepakati nepakati tembiricha uye kumanikidza. C. Kugadziriswa nekugadzirisa kwekuvhara pamusoro pegedhi uye chigaro zviri nyore kupfuura mamwe marudzi emavhavha emagedhi. 8. Kuchenjerera Kuiswa kweGedhi Valve 1. Usati waiswa, tarisa kamuri yevhavha uye chisimbiso chepamusoro. Hapana tsvina kana jecha rinobvumirwa kunamatira. 2. Mabhoti mune imwe neimwe yekubatanidza chikamu inofanira kusimbiswa zvakafanana. 3. Kutarisa nzvimbo yekuzadza kunoda compaction, kwete chete kuti uone kuiswa chisimbiso chekuzadza, asiwo kuve nechokwadi chokuti gedhi rinovhura nyore. 4. Usati waisa forged simbi gedhi mavharuvhu, vashandisi vanofanira kutarisa vharafu mhando, yekubatanidza saizi uye midhiya kuyerera nzira kuti vaone kuenderana nezvinodiwa vharafu. 5. Pakuisa mavharuvhu egedhi resimbi, vashandisi vanofanira kuchengetedza nzvimbo inodiwa yekutyaira kwevharuvhu. 6. Iyo wiring yechigadzirwa chekutyaira ichaitwa maererano nedhiyabhorosi yedunhu. 7. Forged steel gedhi mavharuvhu anofanira kuchengetedzwa nguva dzose. Hapana kudhumhana zvisina tsarukano uye extrusion inobvumidzwa kukanganisa kuiswa chisimbiso.
