Forged Stainless Steel A182 F316L Trunnion Mounted Ball Valve

Vavu yachitsulo yopangidwa ndi chitsulo ndi valavu yofunikira yomwe imagwiritsidwa ntchito kwambiri pamapaipi amakampani, omwe amagwiritsidwa ntchito kwambiri m'magawo monga petrochemicals, gasi, ndi mphamvu.

Choyamba, mavavu opangidwa ndi zitsulo zopangira zitsulo amakwaniritsa kutsekeka kwamadzimadzi ndikuwongolera kuzungulira kwa gawolo. Chigawo, monga chigawo chapakati cha valavu, chimasintha kutsegula ndi kutseka kwa njira yamadzimadzi kupyolera mu kasinthasintha. Chigawochi chikazungulira kuti chigwirizane ndi mpando wa valve, chimatha kukwaniritsa kutsekedwa kwamadzimadzi ndi kusindikiza. Chigawochi chikazungulira mpaka pomwe sichikukhudzana ndi mpando wa valve, njirayo imatha kutsegulidwa mokwanira kuti ikwaniritse kutuluka kwamadzimadzi. Mfundo yogwiritsira ntchito kasinthasintha uku ingapereke ntchito yodalirika kwambiri yosindikiza komanso kuyendetsa bwino.

Kachiwiri, ma valve opangidwa ndi chitsulo opangidwa ndi chitsulo amakhala ndi kuthamanga kwambiri komanso kukana dzimbiri. Chifukwa cha kufalikira kwake mu machitidwe a mapaipi a mafakitale, ma valve opangidwa ndi zitsulo zopangira zitsulo amafunika kupirira kuthamanga kwambiri ndi kutentha. Choncho, amapangidwa ndi chitsulo champhamvu kwambiri, monga carbon steel, alloy steel, etc., kuti atsimikizire kukana kwake. Pakadali pano, valavu yachitsulo yopangidwa ndi chitsulo imatenga chithandizo chapadera cha anti-corrosion panthawi yopanga, zomwe zimapangitsa kuti zisawonongeke komanso zimagwirizana ndi mitundu yosiyanasiyana ya asidi, alkali ndi zowononga.

Kuphatikiza apo, ma valve opangidwa ndi zitsulo zonyezimira ali ndi mawonekedwe akusintha mwachangu komanso kusindikiza kolimba. Chifukwa cha kusinthasintha kwa gawoli, ma valve opangidwa ndi zitsulo zopangira zitsulo amatha kukwaniritsa ntchito yosinthira mwachangu komanso kuthamanga kwachangu. Pakadali pano, valavu yachitsulo yopangidwa ndi chitsulo imatenga mawonekedwe osindikizira awiri, kuonetsetsa kuti valavu itsekedwa mwamphamvu komanso kupewa kutayikira. Makhalidwe akusintha mwachangu ndi kusindikiza kolimba kumapangitsa mavavu opangidwa ndi zitsulo zachitsulo kukhala oyenera pamikhalidwe yokhala ndi zofunika kwambiri pakuwongolera kuyenda ndi kutayikira kwa mpweya.

Ma valve opangidwa ndi zitsulo zachitsulo amakhala ndi mawonekedwe osavuta komanso osavuta kukonza. Zimapangidwa ndi zigawo zing'onozing'ono, zokhala ndi mawonekedwe ophweka komanso ophweka, kuchepetsa mwayi wolephera ndi kukonza ndalama. Pakalipano, mpira wa valavu yachitsulo yopangidwa ndi zitsulo ukhoza kupasuka kuti ikhale yosavuta kukonza ndi kukonza ntchito.

Mwachidule, ma valve opangidwa ndi chitsulo opangidwa ndi zitsulo amakwaniritsa kutsekeka kwamadzimadzi ndikuwongolera kuzungulira kwa gawolo, ndipo amakhala ndi kukana kwamphamvu komanso kukana dzimbiri. Ilinso ndi mawonekedwe akusintha mwachangu ndi kusindikiza kolimba, koyenera pamikhalidwe yokhala ndi zofunika kwambiri pakuwongolera kuyenda komanso kutulutsa mpweya. Pakalipano, ma valve opangidwa ndi zitsulo zonyezimira amakhala ndi mawonekedwe osavuta komanso osavuta kukonza, omwe angapereke zotsatira zodalirika zogwiritsira ntchito komanso kugwira ntchito kwa nthawi yaitali.

Mapangidwe akuluakulu ndi awa:

- Madigiri 90 oyika ndi kutseka mawonekedwe

- Mapangidwe amoto ndi anti-static

- Tsinde la valve yoletsa kuphulika

- Kusindikiza kawiri pakatikati pa tsinde la valve

Magawo atatu olumikizira zitsulo zopanga zitsulo zokhazikika amagawaniza thupi la valavu kukhala magawo atatu motsatira gawo lomwe limayenderana ndi njira ya valve pamipando iwiri ya valve. Vavu yonseyo ndi yofanana pakatikati pa tsinde la valavu, ndipo imagwiritsidwa ntchito makamaka podula, kugawa, ndikusintha komwe kumayendera sing'anga mumapaipi. Mapangidwe ake akuluakulu a pivot amatsimikizira malo olondola apakati a gawoli pansi pa kupanikizika kwakukulu, kuonetsetsa kuti valve ikugwira ntchito bwino; Mpando wa valve wokhazikika umatenga mawonekedwe a kasupe, omwe amakankhira mpando wa valve kupita kumalo, kuonetsetsa kuti ntchito yabwino yosindikizira ikugwira ntchito polowera ndi kutuluka; Pogwiritsa ntchito valavu yowonongeka, chipinda chapakati cha thupi la valve chikhoza kutulutsa kunja; Pivot imagwiritsa ntchito chitetezo cha anti blowout, kuteteza bwino kutayikira; Mapiritsi otsika otsika amachepetsa torque pang'onopang'ono, kumathandizira kutsegula ndi kutseka kwa valve; Kulumikizana kogwira mtima pakati pa tsinde la valavu ndi thupi la valavu kumatsimikizira kugwira ntchito kwapamwamba kwa chipangizo cha anti-static grounding. Ili ndi ubwino wa ntchito zabwino kwambiri, kudalirika kwakukulu, kugwiritsa ntchito kwakukulu, ndi mtengo wololera.
