Mfundo yogwirira ntchito ndi kukonza ndi kukonza njira ya pneumatic butterfly valve

Vavu ya butterfly ya pneumaticamapangidwa ndi mpweya actuator ndi valavu butterfly. Vavu yagulugufe ya pneumatic imagwiritsa ntchito mbale yagulugufe yozungulira yomwe imazungulira ndi tsinde la valavu potsegula ndi kutseka, kuti azindikire zomwe zikuchitika. Valve ya pneumatic imagwiritsidwa ntchito makamaka ngati valavu yotseka, ndipo imatha kupangidwanso kuti ikhale ndi ntchito yosinthira kapena gawo la valve ndi kusintha. Pakalipano, valavu ya butterfly imagwiritsidwa ntchito pamagetsi otsika komanso aakulu Imagwiritsidwa ntchito kwambiri pa mapaipi apakati.

Mfundo yogwirira ntchito yavalavu ya butterfly ya pneumatic

Mbale yagulugufe ya valavu ya gulugufe imayikidwa m'mimba mwake momwe payipi imayendera. Mu cylindrical channel of the butterfly valve body, mbale yagulugufe yooneka ngati diski imazungulira mozungulira, ndipo mbali yozungulira ili pakati pa 0.°-90°. Pamene kuzungulira kufika 90°, valavu ili yotseguka kwathunthu. Valve ya gulugufe ndi yophweka popanga, yaying'ono kukula kwake ndi kulemera kwake, ndipo imakhala ndi magawo ochepa chabe. Komanso, imatha kutsegulidwa mwachangu ndikutsekedwa ndikungozungulira 90°, ndipo ntchitoyo ndi yosavuta. Pa nthawi yomweyi, valve ili ndi makhalidwe abwino olamulira madzimadzi. Pamene valavu ya gulugufe ili pa malo otseguka, makulidwe a gulugufe ndi kukana kokha pamene sing'anga imayenda kupyolera mu thupi la valavu, kotero kuti kutsika kwapakati kopangidwa ndi valavu kumakhala kochepa kwambiri, kotero kumakhala ndi makhalidwe abwino oyendetsa. Mavavu agulugufe ali ndi mitundu iwiri yosindikiza: chisindikizo chotanuka ndi chisindikizo chachitsulo. Kwa mavavu osindikizira zotanuka, mphete yosindikizira imatha kuikidwa pa thupi la valavu kapena kumangirizidwa pamphepete mwa mbale yagulugufe.

Valve ya butterfly ya pneumatickukonza ndi kukonza zolakwika

1. Dongosolo loyang'anira silinda ndi kukonza

Nthawi zambiri chitani ntchito yabwino yoyeretsa pamwamba pa silinda ndikuthira mafuta pa circlip ya shaft ya silinda. Tsegulani chivundikiro chomaliza cha silinda nthawi zonse pakatha miyezi isanu ndi umodzi kuti muwone ngati pali ma sundries ndi chinyezi mu silinda, komanso momwe mafuta alili. Ngati mafuta opaka mafuta akusowa kapena auma, m'pofunika kugawanitsa silinda kuti muthe kukonza bwino ndikuyeretsa musanawonjezere mafuta opaka mafuta.

2. Kuyendera thupi la valve

Miyezi iliyonse ya 6, yang'anani ngati mawonekedwe a valavu ndi abwino, ngati pali kutayikira pa flange yokwera, ngati kuli koyenera, fufuzani ngati chisindikizo cha valavu chili chabwino, palibe kuvala, ngati mbale ya valve ndi yosinthika, komanso ngati pali nkhani yachilendo yomwe yatsekedwa mu valve.

Njira zophatikizira ma cylinder block ndi njira zolumikizirana ndi zodzitetezera:

Choyamba chotsani silinda ku thupi la valavu, choyamba chotsani chivundikiro pa malekezero onse a silinda, tcherani khutu ku njira ya pisitoni pochotsa pisitoni, kenaka mugwiritseni ntchito mphamvu yakunja kuti mutembenuzire tsinde la silinda mozungulira kuti pisitoni ithamangire kumbali yakunja, ndiyeno mutseke valavu Bowolo limatuluka mpweya pang'onopang'ono ndipo pisitoni ndi mpweya uyenera kuperekedwa pang'onopang'ono, koma pang'onopang'ono mpweya uyenera kuperekedwa. pisitoni idzatulutsa mwadzidzidzi, zomwe ndizowopsa! Kenaka chotsani circlip pa shaft ya silinda, ndipo tsinde la silinda likhoza kutsegulidwa kuchokera kumalekezero ena. tulutsani. Ndiye mutha kuyeretsa gawo lililonse ndikuwonjezera mafuta. Zigawo zomwe zimafunika kudzola ndi: khoma lamkati la silinda ndi mphete yosindikizira pisitoni, rack ndi mphete yakumbuyo, komanso shaft ya gear ndi mphete yosindikizira. Pambuyo popaka mafutawo, iyenera kukhazikitsidwa molingana ndi dongosolo la kugwetsa komanso kusinthana kwa magawowo. Pambuyo pake, iyenera kukhazikitsidwa molingana ndi dongosolo la kugwetsa ndi kusinthika kwa magawowo. Samalani malo a giya ndi choyikapo, ndipo onetsetsani kuti pisitoni imatsikira pamalo pomwe valavu yatseguka. Mphepete mwa kumtunda kwa shaft ya gear imafanana ndi chipika cha silinda mkati mwa malo amkati, ndipo poyambira pamwamba pa tsinde la gear ndi perpendicular kwa cylinder block pamene pisitoni imatambasulidwa kumalo akunja pamene valavu yatsekedwa.

Kuyika kwa thupi la cylinder ndi ma valve ndikuwongolera njira ndi njira zopewera:

Choyamba ikani valavu pamalo otsekedwa ndi mphamvu yakunja, ndiye kuti, tembenuzirani shaft ya valve molunjika mpaka mbale ya valve ikugwirizanitsa ndi mpando wa valve, ndipo nthawi yomweyo ikani silinda pamalo otsekedwa (ndiko kuti, valve yaing'ono pamwamba pa shaft ya cylinder The groove is perpendicular to the cylinder body (kwa valavu yomwe imazungulira valavu), ndiyeno valavu yozungulira valavu ikhoza kuyika valavu yozungulira kukhala ofanana kapena perpendicular kwa valavu thupi), ndiyeno fufuzani ngati wononga mabowo amagwirizana Large kupatuka, ngati pali kupatuka pang'ono, ingotembenuzirani yamphamvu chipika pang'ono, ndiyeno kumangitsa zomangira gulugufe debugging choyamba fufuzani ngati Chalk valavu anaika kwathunthu, solenoid valavu ndi mpweya wosakwanira, 0.±0.05MPA, musanagwiritse ntchito, onetsetsani kuti palibe zinyalala zomwe zayikidwa mu mbale ya valve mu thupi la valve Pakutumiza koyamba ndi ntchito, gwiritsani ntchito batani lachidziwitso cha valve solenoid (coil ya solenoid valve imazimitsidwa panthawi yogwiritsira ntchito, ndipo ntchito yamanja ndiyovomerezeka; pamene ntchito yoyendetsa magetsi ikuchitika, kupotoza kwamanja kumayikidwa ku 0 ndi kutsekedwa kwamanja; valavu, 1 ndi kutsegula valavu, ndiko kuti, valavu imatsegulidwa pamene mphamvu imatsegulidwa, ndipo valavu imatsekedwa pamene mphamvu yatha.

Zikapezeka kuti wopanga valavu ya butterfly ya pneumatic imachedwa pang'onopang'ono pamalo oyamba a valve yotsegulira panthawi yotumiza ndikugwira ntchito, koma imathamanga kwambiri ikangosuntha. Mwamsanga, pamenepa, valavu imatsekedwa mwamphamvu kwambiri, ingosinthani kugunda kwa silinda pang'ono (sinthani zomangira zosinthira silinda kumapeto kwa silinda pang'ono panthawi imodzi, pamene mukukonzekera, valavu iyenera kusunthidwa pamalo otseguka, ndiyeno gwero la mpweya lizimitsidwa Zimitsani ndikusintha), sinthani mpaka valavu ikhale yosavuta kutsegula ndi kutseka pamalo opanda lea. Ngati muffler ndi chosinthika, liwiro kusintha valavu akhoza kusintha. Ndikofunikira kusintha muffler kuti mutsegule koyenera kwa liwiro losinthira valavu. Ngati kusinthako kuli kochepa kwambiri, valavu ikhoza kugwira ntchito.
