Thevalve pachipatandi chipata chotsegula ndi chotseka.Mayendedwe a chipata ndi perpendicular kwa malangizo a madzimadzi.Valve yachipata imatha kutsegulidwa kwathunthu ndikutsekedwa kwathunthu, ndipo sichingasinthidwe kapena kugwedezeka.Valve yachipata imasindikizidwa ndi kukhudzana pakati pa mpando wa valve ndi mbale ya pachipata.Kawirikawiri, malo osindikizira adzakhala akuyang'ana ndi zipangizo zachitsulo kuti awonjezere kukana, monga 1Cr13, STL6, zitsulo zosapanga dzimbiri, etc.Malinga ndi zipata zosiyanasiyana, valavu yachipata imagawidwa kukhala valavu yolimba yachipata ndi valve yotsekemera.

Kutsegula ndi kutseka kwa valve ya chipata ndi chipata, ndipo kayendetsedwe ka kayendetsedwe ka chipata ndi perpendicular kwa kayendedwe ka madzi.Thevalve pachipatazitha kutsegulidwa kwathunthu ndikutsekedwa kwathunthu, ndipo sizingasinthidwe kapena kugwedezeka.Chipatacho chili ndi malo awiri osindikizira.Malo awiri osindikizira a ma valve omwe amagwiritsidwa ntchito kawirikawiri amapanga mawonekedwe a wedge.Ngodya ya wedge imasiyanasiyana ndi magawo a valve, nthawi zambiri 5 °, ndi 2 ° 52' pamene kutentha kwapakati sikuli kwakukulu.Chipata cha valavu ya chipata cha wedge chingapangidwe chonse, chotchedwa chipata cholimba;imathanso kupangidwa kukhala chipata chomwe chingathe kutulutsa pang'ono pang'onopang'ono kuti apititse patsogolo luso lake ndikupanga kupatuka kwa kusindikiza pamwamba pa ngodya panthawi yokonza.Mbaleyo imatchedwa chipata chotanuka.Pamene valve yachipata imatsekedwa, malo osindikizira amatha kusindikizidwa kokha ndi kupanikizika kwapakati, ndiko kuti, kudalira kupanikizika kwapakati kuti akanikizire kusindikiza pamwamba pa chipata ku mpando wa valve kumbali ina kuti atsimikizire kusindikizidwa kwa kusindikiza. pamwamba, komwe ndi kudzisindikiza.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.Chipata cha valavu yachipata chimayenda motsatira tsinde la valve, chomwe chimatchedwa valavu ya chipata chokwera, chomwe chimadziwikanso kuti valavu yokwera.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 kuli 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 zomwe zimachitika 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, ndiko kuti, sitiroko.Kwa enama valve pachipata, mtedza wa tsinde umayikidwa pachipata, ndipo kusinthasintha kwa gudumu lamanja kumayendetsa tsinde la valve kuti lizizungulira, zomwe zimapangitsa kuti chipata chikwere.Vavu yamtunduwu imatchedwa valavu yachipata chozungulira, kapena valavu yachipata chakuda.
