1. Mfundo yosindikiza ya Taikevalavu ya mpira woyandama
Gawo lotsegula ndi lotseka la Taike Floating Ball Valve ndi gawo lomwe lili ndi dzenje lolingana ndi kukula kwa chitoliro chapakati.Mpando wosindikizira wopangidwa ndi PTFE umayikidwa pamapeto olowera ndi kumapeto, omwe ali mu valve yachitsulo.Mu thupi, pamene bowo mu bwalo likudutsana ndi njira ya payipi, valavu imakhala yotseguka;pamene kudzera dzenje mu gawolo ndi perpendicular kwa payipi njira, valavu ali chatsekedwa boma.Valavu imatembenuka kuchoka kutseguka kupita kutsekedwa, kapena kuchoka kutsekedwa kupita kutseguka, mpirawo umatembenukira 90 °.
Pamene valavu ya mpira ili pamalo otsekedwa, kupanikizika kwapakati pamapeto olowera kumagwira mpirawo, kumapanga mphamvu yokankhira mpirawo, kotero kuti mpirawo umakankhira mwamphamvu mpando wosindikizira pamapeto, ndipo kupsinjika maganizo kumapangidwa. Pamwamba pampando wosindikizira kuti apange malo olumikizirana Mphamvu pagawo lililonse la malo olumikizirana amatchedwa kukakamiza kwapadera q kwa chisindikizo cha valve.Pamene kupanikizika kwapadera kumeneku kuli kwakukulu kuposa kukakamizidwa kwapadera kofunikira pa chisindikizo, valavu imapeza chisindikizo chogwira mtima.Njira yosindikizira yamtunduwu yomwe sidalira mphamvu yakunja, imasindikizidwa ndi kupanikizika kwapakatikati, imatchedwa kusindikiza kwapakatikati.
Kuyenera ananena kuti miyambo mavavu mongama valve a globe, ma valve pachipata, pakativalavu butterfly, ndi ma plug valves amadalira mphamvu yakunja kuti agwire pampando wa valve kuti apeze chisindikizo chodalirika.Chisindikizo chopezedwa ndi mphamvu yakunja chimatchedwa chisindikizo chokakamiza.Mphamvu yosindikizira yokakamiza yomwe ikugwiritsidwa ntchito kunja ndi yosawerengeka komanso yosadziwika bwino, zomwe sizikugwirizana ndi kugwiritsa ntchito valve kwa nthawi yaitali.Mfundo yosindikiza ya Taike mpira valve ndi mphamvu yomwe imagwira pampando wosindikiza, yomwe imapangidwa ndi kukakamizidwa kwa sing'anga.Mphamvu imeneyi ndi yokhazikika, imatha kulamuliridwa, ndipo imatsimikiziridwa ndi mapangidwe.
2. Taike zoyandama mpira valavu kapangidwe makhalidwe
(1) Pofuna kuonetsetsa kuti gawolo likhoza kupanga mphamvu ya sing'anga pamene gawolo liri lotsekedwa, gawolo liyenera kukhala pafupi ndi mpando wosindikizira pamene valavu yasonkhanitsidwa pasadakhale, ndipo kusokoneza kumafunika kuti apange Pre-mangirira chiŵerengero kuthamanga, izi chisanadze kumangitsa chiŵerengero kuthamanga Ndi 0.1 nthawi ntchito mphamvu ndi osachepera 2MPa.Kupeza kwa chiŵerengero cha preload ichi kumatsimikiziridwa kwathunthu ndi miyeso ya geometric ya mapangidwe.Ngati kutalika kwaulele pambuyo pa kuphatikizika kwa gawolo ndi mipando yotsekera ndi kutulutsa ndi A;pambuyo pa matupi a valve kumanzere ndi kumanja ataphatikizidwa, mkati mwake muli chigawocho ndipo m'lifupi mwa mpando wosindikizira ndi B, ndiye kuti kukakamizidwa kofunikira kumapangidwa pambuyo pa msonkhano.Ngati phindu ndi C, liyenera kukwaniritsa: AB=C.Mtengo wa C uwu uyenera kutsimikiziridwa ndi miyeso ya geometrical ya magawo omwe akonzedwa.Zingaganizidwe kuti kusokoneza uku C ndikovuta kudziwa ndikutsimikizira.Kukula kwa mtengo wosokoneza kumatsimikizira mwachindunji ntchito yosindikiza ndi torque yogwiritsira ntchito valve.
(2) Ziyenera kuwonetsedwa makamaka kuti valavu ya mpira woyandama wam'nyumba inali yovuta kuwongolera chifukwa cha kusokoneza panthawi ya msonkhano, ndipo nthawi zambiri inkasinthidwa ndi ma gaskets.Opanga ambiri adatchulapo gasket iyi ngati chosinthira chowongolera m'bukuli.Mwanjira iyi, pali kusiyana kwina pakati pa ndege zolumikizira za matupi akuluakulu ndi othandizira ma valve panthawi ya msonkhano.Kukhalapo kwa kusiyana kwina kumeneku kumapangitsa kuti ma bolt asungunuke chifukwa cha kusinthasintha kwapakati komanso kutentha komwe kumagwiritsidwa ntchito, komanso kuchuluka kwa mapaipi akunja, ndikupangitsa kuti valavu ikhale kunja.kutayikira.
(3) Pamene valavu ili mu malo otsekedwa, mphamvu yapakati pamapeto olowera imagwira ntchito pamtunda, zomwe zidzachititsa kuti pakatikati pa geometric sphere, pakhale kukhudzana kwambiri ndi mpando wa valve. kutulutsa ndikuwonjezera kupsinjika pagulu losindikiza, potero kupeza kudalirika.Chisindikizo;ndipo mphamvu yowonjezereka ya mpando wa valve pamapeto olowera pokhudzana ndi mpirawo idzachepetsedwa, zomwe zidzakhudza ntchito yosindikiza ya mpando wosindikizira wolowera.Mtundu uwu wa valavu ya mpira ndi valavu ya mpira yomwe imasuntha pang'ono pakati pa geometric pakati pa malo ogwirira ntchito, omwe amatchedwa valavu yoyandama.Valavu yoyandama ya mpira imasindikizidwa ndi mpando wosindikizira kumapeto, ndipo sizikudziwika ngati mpando wa valve pamapeto olowera uli ndi ntchito yosindikiza.
(4) Taike yoyandama valavu ya mpira ndi mbali ziwiri, ndiye kuti, njira ziwiri zapakati zotuluka zimatha kusindikizidwa.
(5) Mpando wosindikiza pomwe mabwalo amalumikizidwa amapangidwa ndi zida za polima.Magawo akamazungulira, magetsi osasunthika amatha kupangidwa.Ngati palibe mapangidwe apadera a anti-static, magetsi osasunthika atha kuwunjikana pamagawo.
(6) Kwa valavu yokhala ndi mipando iwiri yosindikizira, valavu ya valve imatha kudziunjikira pakati.Sing'anga ina imatha kuwonjezeka mosadziwika bwino chifukwa cha kusintha kwa kutentha komwe kumazungulira komanso magwiridwe antchito, kuwononga malire a valve.Chidwi chiyenera kuperekedwa.
