5 Mapoinzi Akakosha ekuchengeta mupfungwa nezvekugadzwa kwevharuvhu. 1 Direction uye chinzvimbo Mavharuvhu mazhinji anotungamira Semuenzaniso, globe valve, throttle valve, pressure yekudzikisa vharafu, cheki vharafu, nezvimwewo, kana yakaiswa mureverse, inokanganisa mashandisiro ekushandisa uye hupenyu (senge throttle valve), kana kwete. shanda zvachose (sekumanikidza kuderedza vharafu), uye kunyange kukonzera njodzi (senge cheki vharafu). Mavharuvhu akazara ane mavara anotungamira pamuviri. Kana zvisina kudaro, inofanira kunyatsozivikanwa maererano nemutemo wekushanda kwevhavha. Kamuri yevharuvhu yakatenderedza vharuvhu yepasirese ndeye asymmetrical, fluid kuti irege kubva pasi kuenda kumusoro kuburikidza nevharuvhu chiteshi, saka kupikisa kwemvura kudiki (kunotemerwa nechimiro), yakavhurika basa-inoponesa (nekuda kwepakati kudzvanywa kumusoro) , yakavharwa mushure mepakati pekumanikidza kurongedza, nyore kugadzirisa, ichi ndicho chikonzero valve yeglobe isingagoni kuisa chokwadi. Mamwe mavharuvhu ane maitiro awo. Chinzvimbo chekuisa vharafu chinofanira kunge chiri nyore kushanda Kunyange kana kuiswa kwakaoma kwechinguva, zvakakosha kufunga nezvebasa renguva refu remushandisi. Zvirinani vharafu handwheel uye kurongeka kwechipfuva (kazhinji 1.2 metres kubva pauriri hwekushanda), kuitira kuti kuvhura nekuvhara kwevhavha kusashanda zvishoma. Floor valve handwheel inofanira kunge yakatarisa kumusoro uye kwete kurereka kudzivirira kushanda kusina kunaka. Ivhavha yemuchina wemadziro zvinoenderana nemidziyo, uye mushandisi anofanirawo kusiiwa akamira. Kuti udzivise kushanda kwedenga, kunyanya asidhi uye alkali, toxic media, zvikasadaro haina kuchengetedzeka. The gedhi harifaniri inverted (ndiko kuti, handwheel iri pasi), zvikasadaro svikiro achachengetwa mubutiro nzvimbo kwenguva yakareba, nyore corrode hunde, uye zvimwe muitiro zvinodiwa taboo. Izvo zvakanyanya kusagadzikana kutsiva kurongedza panguva imwe chete. Vhura STEM GATE VALVES, USAISE pasi pevhu, zvikasadaro nekuda kwekunyorova kwehunde yakafumurwa. Simudza cheki vharafu, kuisirwa kuve nechokwadi kuti vharafu disc vertical, kuitira kuti kusimudza kuchinjike. Swing cheki vharafu, kana yaiswa kuti ive nechokwadi chekuti pini nhanho, kuitira kuti iite inoshanduka. Ivhavha yekudzikisa pressure ichaiswa yakatwasuka pane horizontal pombi, uye haizorerekera kune chero nzira. 2 Basa rekuvaka Kuisa uye kuvaka kunofanira kungwarira, usarove valve yakagadzirwa nebrittle zvinhu. Pamberi pekugadzika Mhando dzese dzevharuvhu uye zvirevo zvichanyatsotariswa kuti zvinoenderana nezvinodiwa zvekugadzira. (TARIRA kana ZVINOGONA KUSHANDISA MUZVINHU ZVINODIWA maererano nemuenzaniso wevharuvhu nemirayiridzo yefekitari, uye ita mvura kana mhepo miedzo yemhepo kana zvichidiwa.) Mukuwedzera, inofanirawo kuongororwa kana kurongedza kwacho kwakasimba, kana gland bolt ine kukwana kugadzirisa mvumo, uye kutarisa kana hunde uye dhisiki inonzwika, kana paine yakanamatira uye skew chiitiko. Iyo yekuisa chisimbiso pamusoro pevhavha disc inofanira kuvharwa zvakasimba, uye kunaka kweshinda kunofanirwa kuongororwa kune mavharuvhu ane threaded. Mavharuvhu asina kukodzera HAACHAPIWA uye achaiswa akapatsanurwa kana kumakwa. *** Zvimedu muvharuvhu. Nzira yekuisa Paunenge uchisimudza vharafu, tambo haifanire kusungirirwa kune HANDWHEEL KANA STEM KUTI UDZIVIRIRE KUNYANYA KUTI ZVIKAMU ZVINO. INOFANIRA KUSUNGAMIRIRWA KUFUNGA. Mutsara uyo valve yakabatanidzwa inofanira kucheneswa. Mhepo yakadzvanywa inogona kushandiswa kuridza iron oxide filings, jecha, welding slag uye mamwe maturu. Aya marara, kwete nyore nyore kukwenya chisimbiso pamusoro pevhavha, iyo yakakura particles yemarara (yakadai sewelding slag), asiwo inogona kuvhara vharafu duku, kuitira kuti kukundikana kwayo. Paunenge uchiisa SCREW VALVE, KUSIMIRA KUSVIRA (WIRE NEAluminium mafuta OR PTFE RAW material belt) inofanira kuputirwa patambo yepombi, usapinda mukati mevhavha, kuitira kuti udzivise vhoriyamu yekuyeuka kwevhavha, inokanganisa kuyerera kwepakati. Paunenge uchiisa flange mavharuvhu, teerera kuomesa mabhaudhi symmetrically uye zvakaenzana. Ivhavha yevhavha uye pombi flange inofanira kufanana, kujekesa kunonzwisisika, kuti vharafu irege kubudisa kudzvinyirira kwakanyanya, kunyange kutsemuka. Kune brittle zvinhu uye kwete simba rakakwirira revhavha, kunyanya kukoshesa kunofanira kubhadharwa. Ivhavha inosungirirwa nepombi ichave yakasvibiswa kutanga, ipapo chikamu chakavharwa chichavhurwa zvakakwana, uye ipapo welded yakafa. 3 Dziviriro Matanho Mamwe mavharuvhu anofanirwawo kuve nekudzivirirwa kwekunze, kunova kuchengetedza kupisa uye kuchengetedza kutonhora. Iyo insulation layer dzimwe nguva inosanganiswa nemitsetse yemhepo inopisa. Ndeupi rudzi rwevhavha runofanira kupisa kana kutonhora, maererano nezvinodiwa zvekugadzira. In musimboti, apo svikiro svikiro kuderedza tembiricha yakawandisa, kuchakanganisa kugadzirwa kunyatsoshanda kana chando vharafu, unofanira kuramba ichidziya, kunyange kusanganisa kupisa; Ipo vharafu isina kushama, inopesana nekugadzirwa kana kukonzera chando uye zvimwe zvakashata zviitiko, unofanirwa kugara uchitonhora. Insulation zvinhu ndeye asbestos, slag wool, girazi mvere, perlite, diatomite, vermiculite, nezvimwewo; Zvinhu zvinotonhora ndezve cork, perlite, foam, plastiki uye zvichingodaro. 4 Bypass uye mita Mamwe mavharuvhu, kuwedzera kune anodiwa ekudzivirira zvivakwa, zvakare ane bypass uye chiridzwa. Kupfuura kwakaiswa. Zviri nyore kugadzirisa musungo. Mamwe mavharuvhu, akaiswawo bypass. Kuiswa kwebypass kunoenderana nemamiriro evharuvhu, kukosha, uye zvinodiwa zvekugadzira. 5 Kurongedza kutsiva Stock vharafu, kumwe kurongedza kwave kusina kunaka, uye zvimwe hazvienderane nekushandiswa kwemidhiya, inoda kutsiva kurongedza. Fekitori yevhavha haigone kufunga nezve kushandiswa kwezviuru zvemhando dzakasiyana dzemidhiya, bhokisi rekurongedza rinogara rakazadzwa neyakajairwa mudzi, asi kana rashandiswa, rinofanira kurega kurongedza mukati kuti rigadzirise. Paunenge uchitsiva kurongedza, dzvanya mukati denderedzwa nekutenderera. Imwe neimwe mhete seam kusvika 45 madhigirii yakakodzera, mhete uye mhete yakazaruka 180 madhigirii. Kureba kwekurongedza kunofanirwa kufunga nezve nzira yekuti gland ienderere mberi nekudzvanya, uye zvino zvakafanira kurega chikamu chezasi chegland chichitsikirira kamuri yekurongedzera kusvika pakadzika kwakakodzera, iyo inogona kunge iri 10-20% yehupamhi hwese. kurongedza chamber. Pamavharuvhu anodaidzira, iyo yejoin Angle i30 madhigirii. Musono pakati pemhete nemhete inodzika 120 madhigirii. Pamusoro pekurongedza, asi zvakare zvinoenderana nemamiriro chaiwo, kushandiswa kwerabha O-ring (rabha remasikirwo rinopesana ne60 madhigirii Celsius asina simba alkali, butadiene rabha rinopesana ne80 madhigirii emafuta ekristaro, Fluorine rabha rinopesana nemhando dzakasiyana dzekuora. midhiya iri pazasi pe150 madhigirii celsius) matatu akaturikidzana polytetrafluoron mhete (inoshingirira kune zvinoodza media zviri pasi pe200 madhigirii celsius) mhete yendiro yenaironi (inodzivirirwa kusvika 120 madhigirii Celsius ammonia, alkali) nezvimwe zvinogadzira filler. Mutsara weTEflon raw material tepi unogona kuvandudza chisimbiso mhedzisiro uye kuderedza electrochemical corrosion yevhavha hunde. Paunenge uchidzvanya chirungiso, shandura dzinde panguva imwe chete kuti urambe wakatenderedza zvakaenzana, uye kudzivirira kufa zvakanyanya, simbisa gland kumanikidza zvakaenzana, haigone kurereka. Zvakakosha kuchengeta pfungwa idzi mupfungwa pamusoro pekuisa valve! Unhu hwekuisa valve hunobata zvakananga kushandiswa, saka kunyatsoteerera kunofanira kubhadharwa kwairi. (a) valve yekuisa kutungamira uye chinzvimbo Mavharuvhu mazhinji ane gwara, senge globe valve, throttle valve, pressure yekudzikisa vharafu, cheki vharafu, nezvimwewo, kana ikaiswa reverse, inokanganisa kushandiswa kwemhedzisiro uye hupenyu (senge throttle vharafu), kana kusashanda zvachose (sekumanikidza kuderedza vharafu), uye kunyange kukonzera njodzi (yakadai sevhavhavhavha). General valve, pane chiratidzo chekutungamira pamutumbi wevharuvhu; Kana zvisina kudaro, inofanira kunyatsozivikanwa maererano nemutemo wekushanda kwevhavha.
