Malinga ndi ntchito ndi kugwiritsa ntchitovalve pachipatandivalavu ya butterfly, valavu yachipata imakhala ndi mphamvu zochepa zothamanga komanso ntchito yabwino yosindikiza.Chifukwa njira yolowera ya mbale ya valve ya pachipata ndi sing'angayo ili pa ngodya yowongoka, ngati valavu ya pachipata siinasinthidwe pamalo ake pa mbale ya valve, kukwapula kwa sing'anga pa mbale ya valve kumapangitsa kuti mbale ya valve igwedezeke., N'zosavuta kuwononga chisindikizo cha valve yachipata.
Vavu yagulugufe, yomwe imadziwikanso kutivalve yotseka, ndi mtundu wa valve yowongolera yokhala ndi mawonekedwe osavuta.Valavu ya butterfly yomwe ingagwiritsidwe ntchito poyang'anira paipi yapaipi yotsika kwambiri imatanthawuza kuti membala wotseka (disiki kapena mbale yagulugufe) ndi chimbale, chomwe chimazungulira kuzungulira shaft ya valve kuti ikwaniritse kutsegula ndi kutseka.Valavu yomwe ingagwiritsidwe ntchito kuwongolera kutuluka kwamitundu yosiyanasiyana yamadzimadzi monga mpweya, madzi, nthunzi, zotengera zosiyanasiyana zowononga, matope, mafuta, zitsulo zamadzimadzi ndi ma radio radio.Zimagwira makamaka kudula ndi kugwedeza paipi.Vavu ya gulugufe kutsegulira ndi kutseka gawo ndimbale yagulugufe yooneka ngati disc, yomwe imazungulira kuzungulira kwake mu thupi la valve kuti ikwaniritse cholinga chotsegula ndi kutseka kapena kusintha.
Gulugufe mbale imayendetsedwa ndi tsinde la valve.Ngati itembenuza 90 °, imatha kumaliza kutsegula ndi kutseka kumodzi.Posintha mbali yowonongeka ya diski, kutuluka kwa sing'anga kumatha kuwongoleredwa.
Malo ogwirira ntchito ndi sing'anga: Vavu ya butterfly ndi yoyenera kutumizira madzi owononga komanso osawononga m'makina opangira uinjiniya monga wopanga, gasi wamalasha, gasi wachilengedwe, gasi wamafuta am'mizinda, mpweya wotentha ndi wozizira, kusungunula kwamankhwala komanso kuteteza chilengedwe. , nyumbamadzi ndi ngalande, etc. Pa payipi ya sing'anga, amagwiritsidwa ntchito kusintha ndi kudula kutuluka kwa sing'anga.
Thevalve pachipatandi chitseko chotsegula ndi chotseka, kayendetsedwe ka kayendetsedwe ka chipata ndi perpendicular kwa kayendedwe ka madzimadzi, ndipo valavu yachipata imatha kutsegulidwa kwathunthu ndikutsekedwa kwathunthu.Kuti apititse patsogolo kupanga kwake ndikupanga kupatuka kwa mawonekedwe osindikizira panthawi yokonza, chipata ichi chimatchedwa chipata chotanuka.
Pamene valve yachipata imatsekedwa, malo osindikizira amatha kudalira kupanikizika kwapakatikati kuti asindikize, ndiko kuti, kungodalira kupanikizika kwapakati kuti akanikizire kusindikiza pamwamba pa chipata ku mpando wa valve kumbali ina kuti atsimikizire kusindikiza kwa malo osindikizira, omwe ndi odzisindikiza okha.Ma valve ambiri a pakhomo amatsekedwa mwamphamvu, ndiko kuti, pamene valve yatsekedwa, chipata chiyenera kukakamizidwa kumenyana ndi mpando wa valve ndi mphamvu yakunja kuti zitsimikizire kuti malo osindikizira ali olimba.
Njira yoyendetsera: Chipata cha valve yachipata chimayenda molunjika ndi tsinde la valve, lomwe limatchedwanso avalavu yokwera pachipata.Nthawi zambiri, pali ulusi wa trapezoidal pa ndodo yokweza.Kupyolera mu nati pamwamba pa valavu ndi groove yotsogolera pa thupi la valavu, kusuntha kwa rotary kumasinthidwa kukhala kusuntha kwa mzere, ndiko kuti, torque yogwiritsira ntchito imasinthidwa kukhala yoyendetsa.Pamene valavu imatsegulidwa, pamene kutalika kwa chipata kumakhala kofanana ndi 1: 1 nthawi ya valavu, njira yamadzimadzi imakhala yosasunthika, koma malowa sangathe kuyang'aniridwa panthawi ya ntchito.Pogwiritsidwa ntchito kwenikweni, nsonga ya tsinde la valve imagwiritsidwa ntchito ngati chizindikiro, ndiko kuti, malo omwe sangathe kutsegulidwa, monga malo ake otseguka.Pofuna kuganizira zochitika zotsekera chifukwa cha kusintha kwa kutentha, nthawi zambiri zimatsegulidwa ku malo apamwamba, ndiyeno kubwerera ku 1 / 2-1 kutembenuka, monga malo a valve yotseguka.Choncho, malo otseguka a valve amatsimikiziridwa molingana ndi malo a chipata (ie sitiroko).Mtedza wa tsinde lachipata umayikidwa pachipata, ndipo kuzungulira kwa gudumu lamanja kumayendetsa tsinde la valve kuti lizizungulira, ndipo chipata chimakwezedwa.Vavu yamtunduwu imatchedwaValve ya chipata cha rotary or valavu yachipata chobisika.
