The ma valve a mpirandi chipata chotsegula ndi chotseka.Mayendedwe a chipata ndi perpendicular kwa malangizo a madzimadzi.Valve yachipata imatha kutsegulidwa kwathunthu ndikutsekedwa kwathunthu, ndipo singasinthidwe 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 kuvala, monga kukwera kwa 1Cr13, STL6, chitsulo chosapanga dzimbiri, etc.Malinga ndi zipata zosiyanasiyana, valavu yachipata imagawidwa kukhala valavu yolimba yachipata ndi valavu ya chipata chotanuka.

Kutsegula ndi kutseka gawo lama valve a mpirandi chipata, ndi kayendedwe ka chipata ndi perpendicular kwa malangizo a madzimadzi.Valve yachipata imatha kutsegulidwa kwathunthu ndikutsekedwa kwathunthu, ndipo singasinthidwe kapena kugwedezeka.Chipatacho chili ndi malo awiri osindikizira.Malo awiri osindikizira a valve mode omwe amagwiritsidwa ntchito kwambiri 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 pakona 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 valavu yatsekedwa, chipata chiyenera kukakamizika kutsutsana ndi mpando wa valve ndi mphamvu yakunja kuti zitsimikizidwe zolimba za malo osindikizira.Chipata cha valavu yachipata chimayenda mofanana ndi tsinde la valve, lomwe limatchedwa valavu ya chipata chokwera, chomwe chimadziwikanso kuti valavu yachipata chokwera.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 valve 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 ma valve ena a zipata, nati ya tsinde imayikidwa pachipata, ndipo kuzungulira kwa gudumu lamanja kumapangitsa kuti tsinde la valve lizizungulira, zomwe zimapangitsa kuti chipata chikwere.Vavu yamtunduwu imatchedwa valavu yachipata chozungulira, kapena valavu yachipata chakuda.
