Mavavu a globe ndi ma valve a pachipata ndi ma valve awiri omwe amagwiritsidwa ntchito kwambiri. Zotsatirazi ndikuyambitsa mwatsatanetsatane kusiyana pakati pa ma valve a globe ndi ma valve a zipata.
1. Mfundo zogwirira ntchito ndizosiyana. Vavu yapadziko lonse lapansi ndi mtundu wa tsinde wokwera, ndipo gudumu lamanja limazungulira ndikunyamuka ndi tsinde la valve. Valve yachipata ndi kuzungulira kwa handwheel, ndipo tsinde la valve limakwera. Mtengo wothamanga ndi wosiyana. Valve yachipata imafuna kutsegulidwa kwathunthu, koma valavu yapadziko lonse lapansi siyitero. Valve yachipata ilibe njira yolowera ndi njira yolowera, ndipo valavu yapadziko lonse lapansi ili ndi zolowera ndi zotuluka! Vavu yolowera kunja ndi valavu ya globe ndi ma valve otseka ndipo ndi ma valve awiri omwe amapezeka kwambiri.
2. Kuchokera pamawonekedwe, valavu yachipata ndi yaifupi komanso yayitali kuposa valavu ya globe, makamaka valavu ya tsinde yokwera imafuna malo apamwamba. Kusindikiza pamwamba pa valavu ya pachipata kumakhala ndi mphamvu yodzisindikiza yokha, ndipo chigawo chake cha valve chimagwirizanitsa kwambiri ndi mpando wosindikizira wa valve ndi kuthamanga kwapakati kuti akwaniritse zolimba komanso kuti asatayike. Malo otsetsereka a valve pachipata cha wedge nthawi zambiri amakhala madigiri 3-6. Pamene kutsekedwa kokakamiza kukuchulukirachulukira kapena kutentha kumasintha kwambiri, pakati pa valve ndi kosavuta kukakamira. Chifukwa chake, mavavu okwera kwambiri komanso othamanga kwambiri achitapo kanthu kuti ma valve core asamamatire mu kapangidwe kake. Pamene valavu yachipata imatsegulidwa ndi kutsekedwa, chigawo cha valve ndi malo osindikizira mpando wa valve nthawi zonse amalumikizana ndi kupakana wina ndi mzake, kotero kuti kusindikiza pamwamba kumakhala kosavuta kuvala, makamaka pamene valve ili pafupi kutseka, kusiyana kwapakati pakati pa kutsogolo ndi kumbuyo kwa valve core ndi kwakukulu, ndipo kuvala kwa malo osindikizira kumakhala koopsa kwambiri.
3. Poyerekeza ndi valavu ya globe yotumizidwa kunja, ubwino waukulu wa valavu yachipata ndikuti kukana kwamadzimadzi kumakhala kochepa. Kuthamanga kwa mpweya wothamanga wa valve wamba yachipata ndi pafupifupi 0.08 ~ 0.12, pamene kukana kwa valve wamba wamba ndi pafupifupi 3.5 ~ 4.5. Mphamvu yotsegula ndi yotseka ndi yaying'ono, ndipo sing'anga imatha kuyenda mbali ziwiri. Zoyipa zake ndizovuta, kukula kwake kwakukulu, komanso kuvala kosavuta kwa malo osindikizira. Malo osindikizira a valve yapadziko lonse ayenera kutsekedwa ndi mphamvu yokakamiza kuti akwaniritse kusindikiza. Pansi pamtundu womwewo, kupanikizika kogwira ntchito ndi chipangizo chomwecho choyendetsa galimoto, torque yoyendetsa ya valve yapadziko lonse ndi 2.5 ~ 3.5 nthawi ya valve yachipata. Mfundoyi iyenera kutsatiridwa pamene mukukonzekera makina oyendetsa magetsi a valve yamagetsi yotumizidwa kunja.
Chachinayi, malo osindikizira a valavu ya globe amangolumikizana wina ndi mzake atatsekedwa kwathunthu. Kutsetsereka kwachibale pakati pa chitsulo chotsekedwa chotsekedwa ndi malo osindikizira ndi ochepa kwambiri, kotero kuvala kwa malo osindikizira kumakhala kochepa kwambiri. Kuvala kwa globe valve kusindikiza pamwamba kumayamba chifukwa cha kukhalapo kwa zinyalala pakati pa pachimake cha valve ndi malo osindikizira, kapena kukwapula kothamanga kwambiri kwa sing'anga chifukwa cha kutseka kotayirira. Mukayika valavu yapadziko lonse lapansi, sing'angayo imatha kulowa kuchokera pansi pamtima wa valve komanso kuchokera pamwamba. Ubwino wa sing'anga yolowera kuchokera pansi pa chivundikiro cha valve ndikuti kulongedza sikukupanikizika pamene valavu yatsekedwa, yomwe imatha kupititsa patsogolo moyo wautumiki wa kulongedza ndikulowetsa kulongedza pamene payipi kutsogolo kwa valve ili pansi. kupanikizika. Kuipa kwa sing'anga yomwe imalowa kuchokera pansi pa valve core ndikuti mphamvu yoyendetsa galimoto ya valve ndi yaikulu, pafupifupi 1.05 ~ 1.08 nthawi ya kumtunda, mphamvu ya axial pa tsinde la valve ndi yaikulu, ndipo tsinde la valve ndi lalikulu. zosavuta kupindika. Pachifukwa ichi, sing'anga yolowera kuchokera pansi nthawi zambiri imakhala yoyenera kwa mavavu ang'onoang'ono ang'onoang'ono, ndipo mphamvu ya sing'anga yomwe ikugwira ntchito pachimake cha valve pamene valavu yatsekedwa imakhala yochepa kuposa 350Kg. Mavavu amagetsi ochokera kunja amagwiritsa ntchito njira yolowera kuchokera pamwamba. Kuipa kwa sing'anga yolowera kuchokera pamwamba kumangotsutsana ndi njira yolowera kuchokera pansi.
5. Poyerekeza ndi ma valve a zipata, ubwino wa ma valve a globe ndi mawonekedwe ophweka, ntchito yabwino yosindikiza, kupanga ndi kukonza kosavuta; kuipa ndi lalikulu madzi kukana ndi lalikulu kutsegula ndi kutseka mphamvu. Mavavu a zipata ndi ma valve a globe ndi ma valve otseguka komanso otsekedwa kwathunthu. Amagwiritsidwa ntchito podula kapena kulumikiza sing'anga ndipo sizoyenera kugwiritsidwa ntchito ngati ma valve oyendetsa kunja. Mitundu yogwiritsira ntchito ma valve a globe ndi ma valve a zipata zimatsimikiziridwa ndi makhalidwe awo. M'mayendedwe ang'onoang'ono, pamene kutsekedwa kwabwinoko kumafunika, ma valve a globe amagwiritsidwa ntchito nthawi zambiri; m'mapaipi a nthunzi ndi mapaipi operekera madzi m'mimba mwake, mavavu a pachipata amagwiritsidwa ntchito chifukwa kukana kwamadzimadzi kumafunika kukhala kochepa.
