Vavu yachipata imatanthawuza valavu yomwe membala wotseka (chipata) amayenda molunjika pakatikati pa ndimeyo.Valve yachipata ingagwiritsidwe ntchito potsegula ndi kutsekedwa kwathunthu mu payipi, ndipo singagwiritsidwe ntchito kusintha ndi kugwedeza.Valve yachipata ndi mtundu wa valve womwe umagwiritsidwa ntchito mosiyanasiyana.Nthawi zambiri, zida zodulira za DN50 zimasankhidwa kuti zigwiritsidwe ntchito, ndipo nthawi zina ma valve a pachipata amagwiritsidwanso ntchito pazida zodulira ndi ma diameter ang'onoang'ono.Valve yachipata imagwiritsidwa ntchito ngati sing'anga-odulidwa, ndipo kutuluka konse kumakhala kolunjika pamene kutsegulidwa kwathunthu.Panthawiyi, kutaya kwapakati kwapakati kumakhala kochepa.Ma valve a zipata nthawi zambiri amakhala oyenera kugwira ntchito zomwe siziyenera kutsegulidwa ndi kutsekedwa kawirikawiri ndikusunga chipata chotseguka kapena kutsekedwa kwathunthu.Sikoyenera kugwiritsidwa ntchito ngati malamulo kapena kupondereza.Kwa sing'anga yothamanga kwambiri, chipata chingayambitse kugwedezeka kwa chipata chikatsegulidwa pang'ono, ndipo kugwedezeka kungathe kuwononga malo osindikizira a chipata ndi mpando wa valve, ndipo kugwedezeka kumapangitsa kuti chipata chiwonongeke. wapakati.
Kuchokera ku mawonekedwe apangidwe, kusiyana kwakukulu ndi mawonekedwe a chinthu chosindikizira chomwe chimagwiritsidwa ntchito.Malinga ndi mawonekedwe a zinthu zosindikizira, mavavu a pachipata nthawi zambiri amagawidwa m'mitundu ingapo, monga: valavu yachipata cha wedge, valavu yachipata chofananira, valavu yachipata chapawiri, valavu yachipata cha wedge, ndi zina zotero. ndi mavavu ofanana pachipata.
Chipatacho chili ndi malo awiri osindikizira.Malo awiri osindikizira omwe amagwiritsidwa ntchito kwambiri pa wedge gate valve amapanga wedge.Ngodya ya wedge imasiyanasiyana ndi magawo a valve, nthawi zambiri madigiri 5.Chipata cha valavu ya chipata cha wedge chingapangidwe chonse, chotchedwa chipata cholimba;Itha kupangidwanso kukhala chipata chomwe chingapangitse kupindika pang'ono kuti chiwongolere kupanga kwake ndikupangitsa kupatuka kwa kosindikiza kosindikiza kosindikiza.Mbaleyo imatchedwa chipata chotanuka.
Pamene valve yachipata yatsekedwa, malo osindikizira angangodalira kupanikizika kwapakati kuti asindikize, ndiko kuti, kudalira kupanikizika kwapakati kuti akanikizire kusindikiza pamwamba pa chipata ku mpando wa valve kumbali ina kuti atsimikizire kusindikizidwa kwa kusindikiza pamwamba, komwe kumadzisindikizira.Ma valve ambiri a zipata amatenga kusindikiza kokakamiza, ndiko kuti, pamene valavu yatsekedwa, chipata chiyenera kukakamizika motsutsana ndi mpando ndi mphamvu yakunja kuti zitsimikizire kuti malo osindikizira ali olimba.
Valve yachipata cha valavu yachipata imayenda mozungulira ndi tsinde la valve, lomwe limatchedwa valavu yokweza tsinde (yomwe imatchedwanso valavu yokwera).Nthawi zambiri pa ndodo yonyamulira pamakhala ulusi wa trapezoidal, kudzera mu mtedza pamwamba pa valavu ndi poyambira pa valavu, kusuntha kozungulira kumasinthidwa kukhala kusuntha kwa mzere, ndiko kuti, torque yogwiritsira ntchito imasinthidwa kukhala mayendedwe opangira.
Pamene valavu imatsegulidwa, pamene kutalika kwa chipata kuli kofanana ndi 1: 1 nthawi ya valavu ya valve, ndime yamadzimadzi imatsekedwa kwathunthu, 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.Kuti muganizire zochitika zotsekera chifukwa cha kusintha kwa kutentha, nthawi zambiri zimatsegulidwa ku malo apamwamba, ndiyeno mmbuyo 1/2 ~ 1 kutembenuka, monga malo a valve yotseguka.Choncho, malo otseguka a valve amatsimikiziridwa ndi malo a chipata (ndiko kuti, sitiroko).
Nortech ndi m'modzi mwa otsogola opanga ma valve ku China omwe ali ndi chiphaso cha ISO9001.
