1. Kodi Vavu Yachipata Ndi Chiyani?
Vavu yachipata ndi valavu yomwe imagwiritsidwa ntchito KUTSEGULA ndi KUZImitsa kutuluka kwa madzi mupaipi.Amatsegula kapena kutseka valavu pokweza chipata kuti alole kapena kuletsa kutuluka kwa madzi.Ziyenera kutsindika kuti valve yachipata sichingagwiritsidwe ntchito poyendetsa kayendetsedwe ka kayendetsedwe kake, koma ndi yoyenera pa ntchito zomwe zimafuna kutuluka kwathunthu kapena kutsekedwa kwathunthu.

2.Gate Valve Kapangidwe kake
Ma valve a zipata nthawi zambiri amakhala ndi zigawo zingapo zofunika:
1) Thupi la valve: Gawo lofunika kwambiri la valve yachipata.Zinthuzo nthawi zambiri zimapangidwa ndi chitsulo cha ductile, WCB, SS, ndi zina.
2) Chipata: gawo lowongolera, lomwe lingakhale mbale yokhala ndi mphira kapena mbale yoyera yachitsulo.
3) Tsinde la valavu: lomwe limagwiritsidwa ntchito kukweza chipata, chopangidwa ndi F6A (yabodza ss 420), Inconel600.
4) Boneti: chipolopolo pamwamba pa thupi la valve, chomwe pamodzi ndi thupi la valve chimapanga chipolopolo chonse cha valve.
5) Mpando wa valve: malo osindikizira pomwe mbale ya pachipata imalumikizana ndi thupi la valve.
3. Kodi Mitundu Yosiyanasiyana ya Mavavu a Zipata Ndi Chiyani?
Kutengera mtundu wa tsinde la valve, imatha kugawidwa kukhala valavu yachipata chosakwera komanso valavu yachipata chokwera.
1)Valve yachipata chosatuluka:Pamwamba pa tsinde la valve ya valavu yobisika ya chipata sichimatambasula ndi gudumu lamanja.Chipinda cha pakhomo chimayenda mmwamba kapena pansi pa tsinde la valve kuti chitsegule kapena kutseka chipata.Ndi mbale ya valve yokha ya valavu yonse yachipata yomwe imakhala ndi kayendetsedwe ka kayendetsedwe kake.
2)Rising stem gate valve (OS&Y chipata valavu):Pamwamba pa tsinde la tsinde lokwera la valve likuwonekera pamwamba pa gudumu lamanja.Pamene valve yachipata imatsegulidwa kapena kutsekedwa, tsinde la valve ndi mbale ya chipata zimakwezedwa kapena kutsitsa pamodzi.
4. Kodi Valve Yachipata Imagwira Ntchito Motani?
Kugwira ntchito kwa valve pachipata ndikosavuta ndipo kumaphatikizapo izi:
1) Malo otseguka: Pamene valve yachipata ili pamalo otseguka, mbale ya pakhomo imakwezedwa kwathunthu ndipo madzi amatha kuyenda bwino kudzera mumsewu wa thupi la valve.
2) Malo otsekedwa: Pamene valve iyenera kutsekedwa, chipata chimasunthidwa pansi.Imaponderezedwa ndi mpando wa valve ndikukhudzana ndi kusindikiza pamwamba pa thupi la valve, kuteteza kutuluka kwa madzi.
5. Kodi Valoti Yachipata Amagwiritsidwa Ntchito Bwanji?
Ma valve a zipata ali ndi ntchito zosiyanasiyana ndipo angagwiritsidwe ntchito m'mafakitale ndi malo osiyanasiyana, monga:
1) Kuchiza kwamadzi: Ma valve ofewa osindikizira amagwiritsidwa ntchito kwambiri pochiza madzi ndi madzi oyipa.
2) Makampani amafuta ndi gasi: Ma valve osindikizira olimba amagwiritsidwa ntchito pamakampani amafuta ndi gasi.
3) Kukonzekera kwa Chemical: Mavavu achitsulo chosapanga dzimbiri ndi oyenera kuwongolera kutuluka kwa mankhwala ndi zakumwa zowononga pakukonza mankhwala.
4) HVAC Systems: Ma valve a zipata amagwiritsidwa ntchito potenthetsa, mpweya wabwino komanso mpweya (HVAC).
Ndiye, Kodi Ma Vavu Achipata Angagwiritsidwe Ntchito Pogwedeza?
Monga tawonera pamwambapa, yankho ndi AYI!Cholinga choyambirira cha valavu yachipata ndi kutsegulidwa kwathunthu ndi kutsekedwa kwathunthu.Ngati agwiritsidwa ntchito mokakamiza kuti asinthe kayendetsedwe kake, kuyenda kolakwika, chipwirikiti ndi zochitika zina zidzachitika, ndipo zidzayambitsa cavitation ndi kuvala mosavuta.
6. Ubwino Wa Chipata Vavu
1) Kuthamanga kwathunthu: Kutsegula kwathunthu, chipatacho chimakhala chofanana ndi pamwamba pa chitoliro, kupereka kutuluka kosasunthika komanso kutsika kochepa.
2) 0 Kutaya: Pamene mbale ya pachipata ikakumana ndi mpando wa valve, chisindikizo cholimba chimapangidwa kuti chiteteze madzi kuti asadutse mu valve.Malo osindikizira pachipata ndi mpando wa valve nthawi zambiri amapangidwa ndi zinthu monga zitsulo kapena zotanuka elastomer kuti akwaniritse kusindikiza kwamadzi ndi kusindikiza mpweya ndi zero kutayikira.
3) Kusindikiza kwapawiri: Ma valve a zipata amatha kusindikiza, kuwapangitsa kukhala osinthasintha m'mapaipi omwe amatha kusintha.
4) Kukonza kosavuta: Palibe chifukwa chochotseratu valve pachipata.Mukungoyenera kutsegula chivundikiro cha valve kuti muwonetsere bwino momwe mkati mwapangidwira.
7. Kuipa Kwa Mavavu Achipata
1) Poyerekeza ndi ma valve ena okhala ndi mawonekedwe osavuta (monga ma valve a butterfly), thupi la valve limagwiritsa ntchito zipangizo zambiri ndipo mtengo wake ndi wapamwamba.
2) Kutalika kwakukulu kwa valve yachipata kuyenera kukhala kochepa, kawirikawiri DN≤1600.Vavu yagulugufe imatha kufika DN3000.
3) Valve yachipata imatenga nthawi yayitali kuti itsegule ndi kutseka.Ngati ikufunika kutsegulidwa mwamsanga, ikhoza kugwiritsidwa ntchito ndi makina oyendetsa mpweya.
