Rising Stem Soft Seling Groove Gate Valve

Vavu yachipata imagwiritsidwa ntchito kwambiri podula zida zokhala ndi DN ≥ 50mm, ndipo nthawi zina ma valve a pachipata amagwiritsidwanso ntchito podula zida zokhala ndi ma diameter ang'onoang'ono.

Kutsegula ndi kutseka kwa valve ya chipata ndi chipata, ndipo kayendetsedwe ka kayendetsedwe ka chipata ndi perpendicular kwa kayendedwe ka madzi.Valve yachipata imatha kutsegulidwa kwathunthu ndikutsekedwa kwathunthu, ndipo singasinthidwe kapena kugwedezeka.Chipatacho chili ndi malo awiri osindikizira.Malo awiri osindikizira a valve yachipata omwe amagwiritsidwa ntchito kwambiri amapanga mawonekedwe a wedge.Ngongole ya wedge imasiyanasiyana ndi magawo a valve, nthawi zambiri 50, ndi 2 ° 52' pamene kutentha kwapakati sikuli kwakukulu.Chipata cha valavu ya chipata cha wedge chikhoza kupangidwa chonse, chomwe chimatchedwa chipata cholimba;imathanso kupangidwa kukhala chipata chomwe chingatulutse pang'ono pang'onopang'ono kuti chiwongolere kupanga kwake ndikulipiritsa kupatuka kwa ngodya yosindikizira pamwamba pakukonza.Mbaleyo imatchedwa chipata chotanuka.Valve yachipata ndiye chida chachikulu chowongolera kuthamanga kapena kutumiza kuchuluka kwa ufa, zinthu zambewu, zinthu za granular ndi kachidutswa kakang'ono.Amagwiritsidwa ntchito kwambiri muzitsulo, migodi, zomangira, tirigu, makampani opanga mankhwala ndi mafakitale ena kuti athetse kusintha kwa kayendedwe kake kapena kudulidwa mwamsanga.

Mavavu a pachipata amatanthauza makamaka mitundu ya ma valve otsekera pachipata chachitsulo, omwe amatha kugawidwa m'mavavu a pachipata, ma valve ofananira pachipata, ndi ma valve olowera pachipata malinga ndi kasinthidwe ka malo osindikizira.Vavu yachipata ikhoza kugawidwa kukhala: mtundu wa chipata chimodzi, mtundu wa chipata chachiwiri ndi mtundu wa chipata chotanuka;valavu yachipata chofanana ikhoza kugawidwa mumtundu umodzi wa chipata ndi mtundu wa chipata chachiwiri.Malingana ndi malo a ulusi wa tsinde la valve, akhoza kugawidwa m'mitundu iwiri: valavu yachipata cha tsinde ndi valavu yosakwera.

Pamene valve yachipata yatsekedwa, malo osindikizira amatha kusindikizidwa kokha ndi kupanikizika kwapakati, ndiko kuti, kudalira kupanikizika kwapakati kuti akanikizire kusindikiza pamwamba pa mbale ya pachipata ku mpando wa valve kumbali ina kuti atsimikizire kusindikizidwa kwa kusindikiza pamwamba, komwe kumadzisindikizira.Ambiri a valve pachipata amakakamizidwa chisindikizo, ndiko kuti, pamene valavu yatsekedwa, chipata chiyenera kukanikizidwa ku mpando wa valve ndi mphamvu yakunja, kuti zitsimikizire kusindikiza pamwamba.

Chipata cha valavu yachipata chimayenda molunjika ndi tsinde la valve, lomwe limatchedwa valavu yokweza tsinde (yotchedwanso valavu yokwera).Kawirikawiri pali ulusi wa trapezoidal pa chokweza, ndipo kupyolera mu mtedza pamwamba pa valve ndi groove yotsogolera pa thupi la valve, kayendetsedwe kameneka kamasintha kukhala mzere wowongoka, ndiko kuti, torque yogwiritsira ntchito imasinthidwa. mu ntchito yokakamiza.

Pamene valavu imatsegulidwa, pamene kutalika kwa chipata cha chipata kumakhala kofanana ndi 1: 1 nthawi ya valavu, kutuluka kwamadzimadzi kumatsekedwa 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 tsinde la valve sikuyenda limatengedwa ngati malo ake otseguka.Kuti muganizire zochitika zotsekera chifukwa cha kusintha kwa kutentha, nthawi zambiri zimatsegulidwa ku malo apamwamba, ndiyeno mutembenuzire 1 / 2-1 kutembenuka, monga malo otseguka a valve.Choncho, malo otseguka a valve amatsimikiziridwa ndi malo a chipata (ndiko kuti, sitiroko).

M'ma valve ena a zipata, mtedza wa tsinde umayikidwa pachipata, ndipo kuzungulira kwa gudumu lamanja kumayendetsa tsinde la valve kuti lizizungulira, ndipo mbale ya pachipata imakwezedwa.Vavu yamtunduwu imatchedwa valavu ya rotary stem gate kapena valavu yachipata chakuda.
