Valavu yamagetsi yamagetsi yamagetsi imatha kutsekedwa mwamphamvu kokha ndi kuzungulira kwa digirii 90 ndi torque yaying'ono yozungulira. Mphuno yamkati yofanana kwathunthu ya thupi la valve imapereka kukana pang'ono ndi njira yowongoka kwa sing'anga.
Kawirikawiri amaonedwa kuti valavu ya mpira ndiyo yabwino kwambiri kutsegulira ndi kutseka mwachindunji, koma chitukuko chaposachedwa chapanga valavu ya mpira kuti igwedezeke ndi kuyendetsa. Mbali yaikulu ya valavu mpira ndi kapangidwe kake yaying'ono, ntchito yosavuta ndi kukonza, oyenera madzi, zosungunulira, asidi ndi gasi zachilengedwe ndi zina zonse ntchito TV, komanso oyenera zinthu osauka ntchito TV, monga mpweya, hydrogen peroxide, methane ndi ethylene. Thupi la valve la valve ya mpira likhoza kukhala lophatikizana kapena lophatikizidwa.
Mpira valavu wakhala chimagwiritsidwa ntchito mafuta, mankhwala, liquefied gasi, madzi ndi ngalande, chakudya, mankhwala, mphamvu m'badwo, papermaking, zomangamanga m'tawuni, mchere, boiler nthunzi dongosolo, tauni, mphamvu atomiki, ndege, roketi ndi madipatimenti ena, komanso moyo wa tsiku ndi tsiku wa anthu.
Vavu yamagetsi ya pulasitiki yamagetsi imapangidwa kuchokera ku valavu ya pulagi. Lili ndi kasinthasintha yemweyo 90 madigiri kukweza kanthu, kusiyana ndi kuti tambala thupi ndi mpira, ndi zozungulira kudzera dzenje kapena njira kudzera olamulira ake. Chiŵerengero cha malo ozungulira ku doko la tchanelo chiyenera kukhala chakuti pamene mpira ukuzungulira madigiri 90, cholowera ndi chotulukira chiyenera kukhala chozungulira, kuti athetse kutuluka.
Valavu yamagetsi yamagetsi yamagetsi imatha kutsekedwa mwamphamvu kokha ndi kuzungulira kwa digirii 90 ndi torque yaying'ono yozungulira. Mphuno yamkati yofanana kwathunthu ya thupi la valve imapereka kukana pang'ono ndi njira yowongoka kwa sing'anga.
Kawirikawiri amaonedwa kuti valavu ya mpira ndiyo yabwino kwambiri kutsegulira ndi kutseka mwachindunji, koma chitukuko chaposachedwa chapanga valavu ya mpira kuti igwedezeke ndi kuyendetsa. Mbali yaikulu ya valavu mpira ndi kapangidwe kake yaying'ono, ntchito yosavuta ndi kukonza, oyenera madzi, zosungunulira, asidi ndi gasi zachilengedwe ndi zina zonse ntchito TV, komanso oyenera zinthu osauka ntchito TV, monga mpweya, hydrogen peroxide, methane ndi ethylene.
Thupi la valve la valve ya mpira likhoza kukhala lophatikizana kapena lophatikizidwa. Mfundo yogwirira ntchito ndi ntchito yothandiza ya valavu yamagetsi ya pulasitiki yogwiritsira ntchito valavu ya mpira ndikupangitsa kuti valavu ikhale yosatsekedwa kapena yotsekedwa pozungulira valavu.
Mpira valavu lophimba kuwala, ang'onoang'ono, akhoza kukhala awiri lalikulu, kusindikiza odalirika, dongosolo losavuta, kukonza yabwino, kusindikiza pamwamba ndi ozungulira padziko nthawi zambiri chatsekedwa, sikophweka kukokoloka ndi sing'anga, chimagwiritsidwa ntchito m'mafakitale osiyanasiyana.
Valve yamagetsi yamagetsi yamagetsi ndi valavu ya pulagi ndi ya mtundu womwewo wa valavu, gawo lake lotseka ndilo mpira, ndipo mpirawo umazungulira pakati pa mzere wapakati wa thupi la valve kuti mutsegule ndi kutseka valavu. Vavu ya mpira imagwiritsidwa ntchito kwambiri podula, kugawa ndikusintha mayendedwe apakati pamapaipi. Valve yamagetsi yamagetsi yamagetsi ndi mtundu watsopano wa valve womwe umagwiritsidwa ntchito kwambiri m'zaka zaposachedwa.
Ili ndi zabwino izi:
1. Kukaniza kwakung'ono kwamadzimadzi, mphamvu yake yotsutsa ndi yofanana ndi kutalika kwa gawo la chitoliro.
2. Mapangidwe osavuta, voliyumu yaying'ono ndi kulemera kopepuka.
3. Ndi yolimba komanso yodalirika. Pakadali pano, zinthu zosindikizira za valve ya mpira zimapangidwa ndi pulasitiki yokhala ndi ntchito yabwino yosindikiza, ndipo zimagwiritsidwa ntchito kwambiri mu vacuum system.
4. Kuchita bwino, kutsegula mofulumira ndi kutseka, kuchokera ku kutsegula kwathunthu mpaka kutseka kwathunthu kwa 90 ° kuzungulira, koyenera kuwongolera kutali.
5. Kukonzekera kosavuta, kapangidwe kosavuta ka valve ya mpira, mphete yosindikizira yosunthika, disassembly yosavuta ndi kusintha.
6. Pamene valavu yatsegulidwa kapena kutsekedwa kwathunthu, malo osindikizira a mpira ndi mpando wa valve amasiyanitsidwa ndi sing'anga, ndipo sing'angayo sichidzayambitsa kukokoloka kwa valve yosindikiza pamwamba.
7. Mitundu yosiyanasiyana ya ntchito, m'mimba mwake kuchokera ku ang'onoang'ono mpaka mamilimita angapo, mpaka mamita angapo, kuchokera ku vacuum yapamwamba kupita ku kuthamanga kwambiri kungagwiritsidwe ntchito.
Vavu ya mpira imagwiritsidwa ntchito makamaka kulumikiza kapena kutsekereza sing'anga yamapaipi, makamaka m'magawo omwe amafunikira kutsegula ndi kutseka mwachangu, monga kutsitsa mwadzidzidzi. Chifukwa cha mawonekedwe ake osavuta, magawo ochepa, kulemera kwake ndi ntchito yabwino yosindikiza, imagwiritsidwa ntchito kwambiri
