Pulagi-mu valavu yowongolera kuthamanga kwa DLF08-00

Valve yachipata cha valavu yothandizira imatanthawuza valavu yachipata yomwe imatseka (chipata) ndikuyenda molunjika pamzere wapakati. Valve ya chitseko imagwiritsidwa ntchito kulumikiza mapaipi. Valve yachipata ndi valve yomwe imagwiritsidwa ntchito kwambiri. Nthawi zambiri amagwiritsidwa ntchito pazida zodulira ndi DN≥50 mm. Mavavu a pachipata ali ndi izi: ① Kutsekeka kwamadzi pang'ono. ② Mphamvu yakunja yofunikira kuti mutsegule ndi kutseka valve yothandizira mwachindunji ndi yaying'ono. (3) chitsogozo cha zinthucho sichimaletsedwa. (4) ikatsegulidwa kwathunthu, malo osindikizira sagwedezeka pang'ono ndi zinthu zogwirira ntchito kusiyana ndi valavu yodulidwa. ⑤ Chiwerengerocho ndi chophweka kwambiri ndipo njira yopangira ndi yabwino. Mavavu a pachipata alinso ndi zofooka zina: ① Kutalika kwake ndi digiri yotsegulira ndizokulirapo. Malo amkati ofunikira kuti asonkhanitse ndi okulirapo. ② Panthawi yotsegula ndi kutseka, pali mikangano pakati pa malo osindikizira, omwe ndi osavuta kuyambitsa mikangano. ③ Mavavu a pachipata nthawi zambiri amakhala ndi malo awiri osindikizira, omwe ndi ovuta kupanga, kukonza, kupera ndi kukonza. Ma valve a zipata amatha kugawidwa mu: (1) ma valve a zipata zofananira: malo osindikizira amafanana ndi tsinde, ndiye kuti, malo awiri osindikizira amafanana. Mu mavavu a zipata zofananira, kapangidwe kamene kamakhala ndi thrust wedge ndiyofala kwambiri, ndiko kuti, pali ma wedges awiri pakati pa zipata ziwiri. Vavu yachipata ichi ndi yoyenera mavavu a pachipata okhala ndi mainchesi ochepa (DN40-300mm) mumagetsi otsika. Palinso mbale ya masika pakati pa nkhosa ziwiri zamphongo, ndipo kasupe wa torsion amatha kuyambitsa mphamvu yolimba, yomwe imakhala yopindulitsa kusindikiza chisindikizo cha valve yamagetsi yamagetsi. (2) Valavu yachipata cha Wedge: malo osindikizira amapanga ngodya inayake yokhala ndi nsonga yowongoka, ndiko kuti, malo awiri osindikizira amapanga valavu ya chipata. Makona owoneka bwino a malo osindikizira nthawi zambiri amakhala 2 52', 3 30', 5, 8, 10, etc. Chinsinsi cha ngodyayo ndi kutentha kwa zinthu. Nthawi zambiri, kutentha kukakhala kokwera kwambiri, m'pamenenso mbali yowonera iyenera kukhala yochepetsera mwayi wokwatirana pamene kutentha kumasintha.
