Zhongfa Valve ndi kampani yopanga zida za ma valve a gulugufe ndi ma valve a gulugufe, yomwe idakhazikitsidwa mu 2006, ikupereka zida za ma valve ndi ma valve a gulugufe kumayiko oposa 20 padziko lonse lapansi, kenako, Zhongfa Valve idzayambitsa njira yodziwitsira mwatsatanetsatane zida za ma valve a gulugufe.
Valavu ya gulugufe imakhala ndi zigawo zotsatirazi, mayina a ziwalo za gulugufe ndi thupi la valavu, diski ya valavu, shaft ya valavu, mpando wa valavu, malo otsekera, ndi choyendetsera ntchito, tsopano, tikuwonetsani zigawo za valavu ya gulugufe izi chimodzi ndi chimodzi.
# 1 Zigawo za valavu ya gulugufe - Thupi la valavu
Timakambirana za thupi la valavu pankhani yolumikizira ndi zinthu
1. Kawirikawiri, malinga ndi njira zosiyanasiyana zolumikizira, mavavu a gulugufe ali ndi mtundu wa flange, mtundu wa wafer, ndi mtundu wa lug, ndipo mitundu yoyerekeza ikuwonetsedwa pachithunzichi. Pa mtundu uliwonse wa kulumikizana, pali kusiyana kochepa malinga ndi mawonekedwe osiyanasiyana, monga valavu ya gulugufe ya wafer, Zhongfa Valve ili ndi mawonekedwe ofanana awa.
2. Malinga ndi zinthuzo, zomwe zimafala kwambiri ndi thupi lachitsulo chosungunuka, thupi lachitsulo cha kaboni, thupi lachitsulo chosapanga dzimbiri, thupi la mkuwa, ndi thupi lachitsulo chapamwamba kwambiri.
# 2Zigawo za valavu ya gulugufe--Chimbale cha Vavu
Kalembedwe ka diski ya valavu kamasiyananso, diski ya pin, diski yopanda pin, diski yokhala ndi rabara, diski yokhala ndi nayiloni, diski yopangidwa ndi electroplated, ndi zina zotero. Kawirikawiri, diski ya valavu imasankhidwa malinga ndi momwe ntchito ikuyendera komanso pakati.
Pa diski yopanda pin, pali through shaft ndi double half shaft, diski yopanda pin imachepetsa chiopsezo cha kutayikira kwa madzi, pa diski yokhala ndi pin, mwina pin yatha kapena yachita dzimbiri patatha nthawi yayitali, media kuchokera pa pin pa diski yomwe imatuluka dzenje la shaft. Tikufuna kusankha diski yopanda pin kwa kasitomala wathu.
# 3 Zigawo za valavu ya gulugufe -- Chopindira cha Valuvu
Chopondera cha valavu ya gulugufe chomwe chimatchedwanso tsinde, chimagwiritsidwa ntchito potumiza, chimalumikizidwa ku actuator kapena chogwirira, zotsatirazi zimayendetsa mwachindunji kuzungulira kwa mbale ya valavu, kuti zikwaniritse kusintha kwa valavu ya gulugufe kapena udindo wosintha.
1. Kuchokera kuzinthu: Zipangizo za spindle nthawi zambiri zimapangidwa ndi chitsulo chosapanga dzimbiri ndi chitsulo cha kaboni, ndipo code yake ndi: chitsulo chosapanga dzimbiri (2cr13, 304, 316, 316L), chitsulo cha kaboni (35, 45, Q235).
2. Kuchokera ku kalembedwe: valavu ya gulugufe kudzera mu shaft (kumanzere) ndi valavu ya gulugufe yokhala ndi theka la shaft (kumanja).
a: Ponena za mtengo: shaft ya theka lachiwiri ndi yokwera mtengo kuposa shaft yodutsa.
b: Ponena za kagwiritsidwe ntchito: double half-shaft imatha kuchita zoposa DN300, ndipo through-shaft imatha kuchita DN800.
c: Zolumikizira zimagwiritsidwa ntchito mosiyanasiyana: zolumikizira kudzera mu shaft zitha kugwiritsidwa ntchito pa ma valvu a gulugufe opindidwa okhala ndi chiwongolero chochepa cha zinyalala. Ma valvu a gulugufe awiri okha ndi omwe angagwiritsidwe ntchito, ndipo chiwongolero cha zinyalala ndi chachikulu.
d: Kupanga: through-shaft yopanda pini ndiyo njira yoyambira pakupanga, kapangidwe kosavuta, kukonza shaft, mavuto awiri opanga theka la shaft, nthawi zambiri amagawidwa m'magulu a shaft yapamwamba, ndi shaft yotsika.
# 4 Zigawo za valavu ya gulugufe --Mpando wa Valuvu
Mpando wa rabara wa valavu ya gulugufe yofewa ungagawidwe m'magulu awiri: mpando wa rabara yolimba kumbuyo ndi mpando wa rabara yofewa kumbuyo, ndipo mpando wa valavu ya gulugufe yolimba kwambiri ndi chisindikizo choyenera komanso chisindikizo cha magawo ambiri.
Kusiyana pakati pa mpando wa rabara wolimba kumbuyo ndi mpando wa rabara wofewa kumbuyo wa valavu ya gulugufe: mpando wolimba kumbuyo umakanikizidwa pa thupi la valavu ndi zinthu zopukutira, zomwe sizingasinthidwe zokha ndipo zimafuna flange yapadera ya valavu ya gulugufe; mpando wofewa kumbuyo umapangidwa ndi chitsanzo, chomwe chingasinthidwe chokha ndipo chingagwiritsidwe ntchito ndi flange yomwe si yapadera pa valavu ya gulugufe.
Ponena za moyo wa utumiki wa mpando wa rabara, moyo wa utumiki wa mpando wofewa wakumbuyo ndi wautali kuposa wa mpando wolimba wakumbuyo, womwe ndi kapangidwe kake ka mbali yayikulu. Njira yogwirira ntchito ya valve nthawi yayitali, shaft ya mpando wa valve imawonongeka. Shaft ya mpando wa valve imatuluka madzi atatha kutuluka mwachindunji kunja kwa thupi la valve. Koma kumbuyo kofewa sikuoneka pamenepa.
# 5 Zigawo za ma valavu a gulugufe -- Malo otsekera
Pali kutseka kofewa ndi kutseka kolimba,Kusankha zipangizo zofewa zotsekera:
1、Rabala (kuphatikiza mphira ya butadiene, mphira ya EPDM, ndi zina zotero), yomwe imagwiritsidwa ntchito kwambiri m'mapaipi otsika mphamvu pamwamba pa mafuta ndi madzi.
2、Pulasitiki (PTFE, nayiloni, ndi zina zotero), zambiri zogwiritsira ntchito zowononga zomwe zili munjira.
Njira yogwirira ntchito: chogwirira, turbo, magetsi, pneumatic, hydraulic
Kusankha zipangizo zomatira zolimba:
1, aloyi wa mkuwa (wa mavavu otsika mphamvu)
2, Chrome zosapanga dzimbiri (za mavavu wamba opanikizika kwambiri komanso apakatikati)
3, Stellite alloy (ya mavavu otentha kwambiri komanso opanikizika kwambiri komanso mavavu amphamvu owononga)
4, ma alloys ochokera ku nickel (opangira zinthu zowononga)
# 6 Zigawo za valavu ya gulugufe -- Choyambitsa Ntchito
Ma valve a gulugufe nthawi zambiri amagwiritsidwa ntchito m'njira zotsatirazi, Hand Lever, Worm Gear, Pneumatic Actuator.
Zogwirizira m'manja nthawi zambiri zimapangidwa ndi zolimba, zotsukidwa ndi mankhwala, komanso zopakidwa ufa. Chogwirizira m'manja nthawi zambiri chimakhala ndi chogwirira ndi chogwirizira cholumikizana, ndipo chimagwiritsidwa ntchito pa DN40-DN250.
Zida za nyongolotsi ndizoyenera ma valve akuluakulu a gulugufe. Bokosi la nyongolotsi nthawi zambiri limagwiritsidwa ntchito pa kukula kwakukulu kuposa DN250, pakadali mabokosi a turbine a magawo awiri ndi atatu.
Ma actuator a pneumatic amagawidwa m'magulu awiri, ma actuator a pneumatic omwe amagwira ntchito kamodzi ndi awiri omwe amagwira ntchito kawiri.
Ma actuator amagetsi amatha kugawidwa m'mitundu yosiyanasiyana yozungulira ndi mitundu ina yozungulira. Mitundu yosiyanasiyana yozungulira imazungulira kuposa 360° kuti mutsegule ndi kutseka valavu pomwe mtundu wina wozungulira nthawi zambiri umazungulira 90° kuti mutsegule ndi kutseka valavu yonse.
Kenako, tiyeni tiwone momwe tingakhazikitsire zida za valavu ya gulugufe pamodzi
