Thewafer dual plate check valveiriwo mhando yevhavhavha yekuongorora ine rotary actuation, asi iine disc kaviri uye inovhara pasi pechiito chechitubu. Iyo dhisiki inosundirwa yakavhurika nepasi-kumusoro fluid, vharafu ine chimiro chakareruka, iyo clamp inoiswa pakati pemaflange maviri, uye saizi diki uye huremu huremu hwakaderera.
Thewafer dual plate check valveine madhisiki maviri echitubu akaremerwa D-akaiswa parib shaft pamhiri pevharuvhu. Ichi chimiro chinopfupisa chinhambwe icho pakati pegiravhiti yedhisiki inofamba. Ichi chivakwa chinoderedzawo uremu hwe diski ne50% kana ichienzaniswa ne-single-disc swing-on check valve yehukuru hwakafanana. Kutenda kumutoro wechirimo, vharuvhu inobata nekukurumidza kusvika kumashure.
Iyo wafer dual plate yekutarisa vharafu yekaviri-lobe lightweight kuvaka inoita kuti chigaro chisimbiso uye kushanda kunyanye kuita.
The refu-ruoko chitubu chiito cheshavishavi maviricheki vharafuinobvumira dhisiki kuvhura uye kuvhara pasina kukwesha chigaro, uye chitubu chinoshanda chakazvimiririra kuvhara disc (DN150 uye pamusoro).
Ruzha rwerutsigiro rwakasungirirwa rweshavishavi rinoputika kaviricheki vharafuinoderedza kupokana uye inoderedza sando yemvura kana yabviswa kuburikidza nedhisiki rakasiyana (guru bore).
Kuenzaniswa neyakajairwaswing cheki mavharuvhu,wafer dual plate check valvekuvaka kunowanzo kusimba, kureruka, kudiki, kunoshanda, uye kudhura. Irivhavha rinosangana nechiyero che API 594, kune madhayamita akawanda, saizi yakatarisana nechiso yevharuvhu iyi ingori 1/4 yevharuvhu yakajairwa, uye uremu i15% ~ 20% yevharuvhu yakajairwa, saka ndizvo. zvakare yakachipa kupfuura swing cheki vharafu. Zvakare zvakareruka kuisa pakati peyakajairwa gaskets uye pombi flanges. Nekuti iri nyore kubata uye inoda chete seti imwe chete yekubatanidza mabhaudhi eflange, inochengetedzawo zvikamu panguva yekuisa, kuchengetedza mari yekuisa uye mari yekugadzirisa zuva nezuva.
Iyo kaviri-flap butterfly cheki vharafu inewo yakakosha yekuvaka maficha anoita iyi vharafu ive yepamusoro-inoshanda isina-impact cheki vharafu. Aya maficha anosanganisira pasina-yakachena kuvhurwa, yakazvimirira chitubu kuvakwa kweakawanda mavharuvhu, uye yakazvimirira disc rutsigiro masisitimu. Zvimwe zvezvinhu izvi hazviwanikwe nemavharuvhu ekutarisa. Iyo wafer mbiri yeplate yekutarisa valve inogona zvakare kugadzirwa nemalugs, maviri flanges uye muviri wakawedzera.
Kutanga, kuvhura nekuvhara nzira
Iyo kaviri-dhisiki yekuvaka ine maviri echitubu-akaremerwa madhisiki (semi-dhisiki) akamiswa kubva papini ine hinged iyo yakamira pakati. Kana iyo mvura inotanga kuyerera, dhisiki inovhura neine simba rinoita (F) rinoshanda pakati penzvimbo yekuisa chisimbiso. The counteractive spring support force (FS) inoshandiswa panzvimbo iri kunze kwepakati pechiso che disc, zvichiita kuti midzi ye disc itange kuvhura. Izvi zvinodzivirira kukakavara pamusoro pekuisa chisimbiso kunoitika kana dhisiki yakavhurwa mumavharuvhu akajairwa, achibvisa kusakara uye kubvaruka pazvikamu.
Kana chiyero chekuyerera chichiderera, chitubu che torsion chinongoerekana chaita, zvichiita kuti disc ivhare uye iende pedyo nechigaro chemuviri, kuderedza rwendo rwekufamba uye nguva yekuvhara. Kana iyo mvura inoyerera ichidzokera kumashure, disc zvishoma nezvishoma inofamba ichiswedera pedyo nechigaro chemuviri, uye mhinduro ine simba yevhavha inokurumidzira zvikuru, inoderedza mhedzisiro yenyundo yemvura uye kubudirira-isina kushanda.
Paunenge uchivhara, chiito chechikamu chesimba rechitubu chinokonzera kuti pamusoro pe diski kuvhara kutanga, kudzivirira kuruma uye kupesana pamudzi we disc, kuitira kuti valve inogona kuchengetedza kutendeseka kwechisimbiso kwenguva yakareba.
2. Yakazvimirira chitubu chimiro
Iyo yekuvakwa kwechirimo (DN150 uye pamusoro) inobvumira kuti torque yakakura ishandiswe kune yega disc uye disc inovhara yakazvimiririra sezvo kuyerera kwemaindasitiri kunochinja. Ongororo dzakaratidza kuti chiitiko ichi chakakonzera kuwedzera kwe25% muhupenyu hwevharuvhu uye kuderedzwa kwe50% munyundo yemvura.
Chikamu chega chega chechidimbu chechidimbu chine zvitubu zvaro zvinopa simba rekuvhara rakasununguka uye rinoiswa pasi pemakona mashoma e140 ° (fig. 3) panzvimbo ye 350 ° yechitubu chakajairika chine mabhuraketi maviri.
3. Yakazvimirira disc kusimisa chimiro
Iyo yakazvimirira hinge chimiro inoderedza friction ne66%, iyo inovandudza zvakanyanya reactivity yevhavha. Sleeve yekutsigira inopinzwa kubva kune hinge yekunze kuitira kuti hinge yekumusoro igone kutsigirwa yakazvimirira nerezasi sleeve panguva yekushanda kwevharuvhu. Izvi zvinobvumira ese madhisiki kuita nekukurumidza uye kuvhara panguva imwe chete, achiwana yakanakisa simba rekuita.
