Zhongfa Valve ndi katswiri wopanga magawo agulugufe ndi ma valve agulugufe, omwe adakhazikitsidwa mu 2006, ndikupereka zida zama valve ndi zida za agulugufe kumayiko opitilira 20 padziko lapansi, kenako, Zhongfa Valve ikhazikitsa tsatanetsatane wa zida za agulugufe.
Valavu yagulugufe imakhala ndi zigawo zotsatirazi, dzina la gulugufe ndi thupi la valavu, valavu Disc, shaft ya valve, mpando wa valve, kusindikiza pamwamba, ndi actuator ya opaleshoni, tsopano, tidzayambitsa magawo a gulugufewa mmodzimmodzi.
# 1 Zigawo za valavu ya gulugufe - Thupi la vavu
Timakambirana za thupi la valve pokhudzana ndi kugwirizana ndi zinthu
1. Nthawi zambiri, molingana ndi njira zosiyanasiyana zolumikizirana, mavavu agulugufe ali ndi mtundu wa flange, mtundu wa wafer, ndi mtundu wa lug, ndipo masitayelo oyandikira akuwonetsedwa pachithunzichi.Pamtundu uliwonse wamalumikizidwe, pali kusiyana kobisika molingana ndi makulidwe osiyanasiyana, monga valavu yagulugufe yawafer, Valve ya Zhongfa ili ndi makulidwe awa wamba.
2. Malingana ndi zinthuzo, zodziwika bwino ndi thupi lachitsulo cha ductile, thupi la chitsulo cha carbon, thupi lachitsulo chosapanga dzimbiri, thupi la mkuwa, ndi thupi lachitsulo cha super duplex.
#2Zigawo za valve butterfly--Valve Diski
Mawonekedwe a diski ya valve amasiyananso, pini disk, pinless disc, disc ndi rabara, Disc ndi Nylon, Electroplated Disc, ndi zina zotero, Kawirikawiri, diski ya valve imasankhidwa malinga ndi momwe ntchito ikugwirira ntchito ndi sing'anga.
Kwa chimbale chopanda pinless, Pali shaft yodutsa ndi shaft iwiri, chimbale chopanda pini chidzachepetsa mwayi wotuluka, kwa Diski yokhala ndi pini, ndizotheka kuti piniyo yatha kapena kudzimbirira pakapita nthawi yayitali, media kuchokera pa pini pa chimbale kuti kutayikira shaft dzenje.Tikufuna kusankha chimbale chopanda pinless cha kasitomala wathu.
# 3 Zigawo za valavu ya butterfly--Vavu Spindle
The gulugufe valavu spindle amatchedwanso tsinde, ntchito kufala, chikugwirizana ndi actuator kapena chogwirira, zotsatirazi mwachindunji amayendetsa valavu mbale kasinthasintha, kuti tikwaniritse valavu gulugufe lophimba kapena kusintha udindo.
1. Kuchokera kuzinthu: Zida za spindle nthawi zambiri zimapangidwa ndi chitsulo chosapanga dzimbiri ndi carbon steel, ndipo code yake ndi: zitsulo zosapanga dzimbiri (2cr13, 304, 316, 316L), carbon steel (35, 45, Q235).
2. Kuchokera pamawonekedwe: valavu yagulugufe kupyola mutsinde (kumanzere) ndi vavu ya gulugufe iwiri theka la shaft (kumanja).
a: Pankhani ya mtengo: shaft iwiri ndi yokwera mtengo kuposa yodutsa.
b: Pankhani ya ntchito: theka-shaft iwiri imatha kuchita zambiri kuposa DN300, ndipo shaft imatha kuchita DN800.
c: Kusinthasintha kwa zoyikapo: zoyikamo kudzera mu shaft zitha kugwiritsidwa ntchito pamavavu agulugufe omangidwa ndi chiwongola dzanja chochepa.Mavavu agulugufe awiri okha a semi-shaft angagwiritsidwe ntchito, ndipo kuchuluka kwa zidutswa ndizokwera.
d: Msonkhano: kupyola-shaft popanda pini ndiyo njira yoyambira pamapangidwe, mapangidwe osavuta, kukonza shaft, zovuta zopanga shaft ziwiri, zomwe zimagawidwa kumtunda wapamwamba, ndi shaft yotsika.
# 4 Zigawo za valavu ya gulugufe--Mpando wa Vavu
Mpando wa mphira wa valavu yagulugufe wofewa ukhoza kugawidwa kukhala mpando wa rabara wolimba kumbuyo ndi mpando wa mphira wofewa, ndipo mpando wa valavu yagulugufe yolimba kwambiri ndi chisindikizo choyenera komanso chisindikizo chamitundu yambiri.
Kusiyanitsa pakati pa mpando wa mphira wolimba ndi mpando wofewa wa mphira wa gulugufe: mpando wokhotakhota umakanizidwa pa thupi la valve ndi ma abrasives, omwe sangalowe m'malo mwawokha ndipo amafuna flange yapadera ya valavu ya butterfly. ;mpando wofewa umapangidwa ndi chitsanzo, chomwe chingasinthidwe chokha ndipo chingagwiritsidwe ntchito ndi flange yomwe siili yapadera kwa valve butterfly.
Pankhani ya moyo wautumiki wapampando wa rabara, moyo wautumiki wampando wofewa wammbuyo ndi wautali kuposa wampando wakumbuyo wolimba, womwe ndi mawonekedwe akulu akulu.Vavu yogwira ntchito nthawi yayitali ya valve mpando shaft kumapeto kuvala.Valve mpando shaft kumapeto kutayikira pambuyo pa mpando wokhotakhota wamadzi kutsetsereka kwamadzi molunjika kunja kwa chodabwitsa cha valavu.Koma msana wofewa suwoneka ngati izi.
# 5 Zigawo za ma valve a butterfly--Kusindikiza pamwamba
pali kusindikiza kofewa ndi kusindikiza kolimba,Kusankhidwa kwa zinthu zofewa zosindikizira:
1, Labala (kuphatikiza mphira wa butadiene, labala wa EPDM, ndi zina), omwe amagwiritsidwa ntchito kwambiri pamapaipi otsika kwambiri pamafuta ndi madzi.
2, Pulasitiki (PTFE, nayiloni, etc.), zambiri kwa zowononga TV mu payipi.
Njira yogwiritsira ntchito: chogwirira, turbo, magetsi, pneumatic, hydraulic
Kusankhidwa kwa zida zosindikizira zolimba:
1, aloyi yamkuwa (kwa mavavu otsika)
2, Chrome zosapanga dzimbiri zitsulo (kwa mavavu wamba mkulu ndi sing'anga kuthamanga)
3, Stellite aloyi (kwa kutentha kwambiri ndi mavavu apamwamba ndi mavavu amphamvu owononga)
4, ma aloyi opangidwa ndi nickel (za media zowononga)
# 6 Zigawo za ma valve a butterfly--Othandizira Oyendetsa
Mavavu agulugufe nthawi zambiri amayendetsedwa motsatira, Hand Lever, Worm Gear, Pneumatic Actuator.
Zovala zam'manja nthawi zambiri zimapangidwa ndi zinthu zolimba, zopangidwa ndi mankhwala, komanso zokutira.Chingwe chamanja nthawi zambiri chimakhala ndi chogwirira ndi cholumikizira cholumikizira, Ndi choyenera DN40-DN250.
Zida za nyongolotsi ndizoyenera mavavu akuluakulu agulugufe.Bokosi la nyongolotsi nthawi zambiri limagwiritsa ntchito makulidwe akulu kuposa DN250, pakadali mabokosi a magawo awiri ndi atatu.
Othandizira pneumatic amagawidwa m'magulu awiri, osachita kamodzi komanso kawiri-kawiri pneumatic actuators.
Ma actuators amagetsi amatha kugawidwa m'mitundu yosiyanasiyana komanso mitundu yotembenukira pang'ono.Mitundu yotembenuza maulendo angapo imatembenuza kuposa 360 ° kuti mutsegule ndi kutseka valavu pamene gawo lotembenuzidwa limatembenuka kawirikawiri 90 ° kuti mutsegule ndi kutseka valavu.
Kenako, tiyeni tiwone momwe tingayikitsire magawo agulugufe pamodzi
