Mu gawo la ma valve a mafakitale,mavavu a gulugufe ozungulira ozunguliraali ndi udindo wofunika chifukwa cha kusinthasintha kwawo komanso kugwira ntchito bwino. Nkhaniyi ikufuna kuwunikira kufunika ndi makhalidwe a valavu yapaderayi, makamaka pankhani yosamalira madzi. Kuphatikiza apo, tikambirana momwe mavalavu agulugufe akuluakulu ozungulira omwe amapangidwa ndi fakitale amapereka zabwino zosayerekezeka pamtengo ndi mtundu.
Choyamba, tiyeni tifufuze mfundo zoyambira za ma valve a gulugufe ozungulira. Odziwika ndi kapangidwe kake kosavuta koma kogwira mtima, valve iyi imakhala ndi diski yomwe ili pakati pa malekezero awiri a flange. Kutseka kolimba pakati pa diski ndi thupi kumatsimikizira kuti palibe kutuluka kwa madzi, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito komwe kumafuna kutsekedwa kwathunthu. Kuphatikiza apo, kapangidwe kake kakang'ono komanso kulemera kwake kopepuka kumathandiza kuyika ndi kukonza mosavuta.
Chimodzi mwa zinthu zabwino kwambiri za valavu ya gulugufe yozungulira yokhala ndi flange ndi diski yake ya mpando wa rabara. Mkati mwa rabara iyi nthawi zambiri imapangidwa ndi EPDM kapena NBR ndipo imagwira ntchito yofunika kwambiri kuti isunge bwino. Kutanuka ndi kukhala nthawi yayitali kwa rabara kumapangitsa kuti igwire bwino ntchito ndipo imaletsa kutuluka kwa madzi ngakhale pamene ikupanikizika kwambiri. Kuphatikiza apo, mavalavu a gulugufe a mpando wa rabara amakhala ogwirizana bwino ndi zinthu zosiyanasiyana monga madzi, ma acid ndi alkali, zomwe zimapangitsa kuti ikhale chisankho choyamba pa njira zosiyanasiyana zoyeretsera madzi.
Ponena za kuyeretsa madzi,valavu ya gulugufe yolimba– mavalavu a gulugufe ozungulira omwe ali ndi flange akuwoneka kuti ndi chuma chamtengo wapatali kumakampaniwa. Pamene kufunika kosamalira bwino madzi kukupitirira kukula, valavu iyi yakhala yankho lodalirika. Imagwiritsidwa ntchito kwambiri popereka madzi, kukonza zimbudzi, kuchotsa mchere m'madzi ndi madera ena. Kutha kwake kulamulira bwino kayendedwe ka madzi ndikuwonetsetsa kuti kuthamanga kwa madzi kutsika pang'ono kumapangitsa kuti ikhale gawo lofunikira kwambiri m'malo oyeretsera madzi.
Tiyeni tikambirane za ubwino wogula ma valve akuluakulu a butterfly concentric kudzera mu malonda a fakitale mwachindunji. Chimodzi mwa ubwino wofunikira kwambiri ndi kutsika mtengo komwe kumapereka. Mwa kuchotsa munthu wapakati ndikuchita zinthu mwachindunji ndi wopanga, makasitomala amatha kusunga ndalama zambiri. Kuphatikiza apo, malonda a fakitale mwachindunji amalola njira zosintha, zomwe zimathandiza makasitomala kusintha valavuyo kuti igwirizane ndi zosowa zawo. Izi zimatsimikizira kuti valavuyo ikukwaniritsa bwino zosowa za makampani oyeretsera madzi, zomwe zimapangitsa kuti ikhale yogwira ntchito bwino komanso yogwira ntchito bwino.
Kuphatikiza apo, malonda a fakitale mwachindunji amatsimikizira kuti zinthu zili bwino kwambiri. Opanga odziwika bwino amatsatira njira zowongolera khalidwe ndipo amagwiritsa ntchito ukadaulo wapamwamba popanga ma valve omwe amakwaniritsa miyezo yapadziko lonse lapansi. Kuphatikiza apo, amapereka chithandizo chokwanira chaukadaulo ndi ntchito yogulitsa pambuyo pogulitsa, kuonetsetsa kuti makasitomala amalandira thandizo losayerekezeka nthawi yonse ya valavu. Kuphatikiza kosayerekezeka kumeneku kwa kugwiritsa ntchito bwino ndalama komanso khalidwe kumapangitsa ma valve a butterfly akuluakulu ozungulira mafakitale kukhala njira yokongola kwa mabizinesi omwe amagwira ntchito yoyeretsa madzi.
Mwachidule, ma valve a gulugufe ozungulira, makamaka akakhala ndi mipando ya rabara, amakhala gawo lofunika kwambiri pa ntchito yokonza madzi. Kutha kwake kupereka chisindikizo cholimba, kulamulira kuyenda kwa madzi ndikuchepetsa kutsika kwa kuthamanga kwa madzi kumapangitsa kuti ikhale chisankho chabwino kwambiri pamakampani awa. Kuphatikiza zinthuzi ndi malonda a fakitale mwachindunji kumathandiza mabizinesi kupeza ma valve otsika mtengo komanso apamwamba omwe amakwaniritsa zosowa zawo zapadera. Mwa kuyika ndalama mu ma valve awa, makampani amatha kuonetsetsa kuti ntchito zokonza madzi zikuyenda bwino komanso mosasokoneza, zomwe pamapeto pake zimathandiza kuti tsogolo likhale losatha komanso lopanda chilengedwe.
Valavu ya TWS, yomwe imadziwikanso kuti Tianjin Tanggu Water Seal Valve Co., Ltd, ndi valavu yolimba ya mpando yothandizira mabizinesi apamwamba kwambiri, zinthu zake ndi valavu ya gulugufe yolimba ya mpando, valavu ya gulugufe yolimba, valavu ya gulugufe yozungulira iwiri, valavu ya gulugufe yozungulira iwiri,valavu yolinganiza, valavu yowunikira mbale ziwiri ya wafer,Y-Strainndi zina zotero.
