I-Zhongfa Valve ingumkhiqizi ochwepheshe wezingxenye zamavalvu ebhabhathane namavalvu ebhabhathane, eyasungulwa ngo-2006, ihlinzeka ngamavalvu nemikhiqizo yezingxenye zamavalvu ebhabhathane emazweni angaphezu kuka-20 emhlabeni, ngokulandelayo, i-Zhongfa Valve izokwethula isethulo esiningiliziwe sezingxenye zamavalvu ebhabhathane.
I-valve ye-butterfly inezingxenye ezilandelayo, amagama ezingxenye ze-butterfly yi-body valve, i-valve Disc, i-valve shaft, isihlalo se-valve, indawo yokuvala, kanye ne-operation actuator, manje, sizokwethula lezi zingxenye ze-butterfly valve ngayinye ngayinye.
#1 Izingxenye zevalvu yebhabhathane -- Umzimba wevalvu
Sixoxa ngomzimba we-valve maqondana nokuxhumana nezinto zokwakha
1. Ngokuvamile, ngokwezindlela ezahlukene zokuxhuma, amavalvu ebhabhathane anohlobo lweflange, uhlobo lwe-wafer, kanye nohlobo lwe-lug, futhi izitayela ezilinganiselwe ziboniswe esithombeni. Kuhlobo ngalunye lokuxhuma, kunomehluko omncane ngokwezinhlobo ezahlukene zesikhunta, njenge-valve yebhabhathane ye-wafer, i-Zhongfa Valve inezinhlobo ezilandelayo zesikhunta.
2. Ngokusho kwezinto ezibonakalayo, ezivamile umzimba wensimbi othambile, umzimba wensimbi yekhabhoni, umzimba wensimbi engagqwali, umzimba wethusi, kanye nomzimba wensimbi ophindwe kabili.
# 2Izingxenye zevalvu yebhabhathane--Idiski Yevalvu
Isitayela sediski yevalvu siyahlukahluka, idiski yephini, idiski engenaphini, idiski enerabha, iDiski eneNylon, iDiski Ene-Electroplated, njalo njalo. Ngokuvamile, idiski yevalvu ikhethwa ngokuya ngezimo zokusebenza kanye nendawo.
Kwidiski engenaphini, kukhona umgodi odlulayo kanye nomgodi ophindwe kabili, idiski engenaphini izonciphisa ingozi yokuvuza, kwiDiski enephini, kungenzeka ukuthi iphini isigugile noma igqwalile ngemva kwesikhathi eside, imidiya evela kwiphini ekwidiski evula umgodi. Singathanda ukukhetha idiski engenaphini yeklayenti lethu.
# 3 Izingxenye zevalvu yebhabhathane--I-Spindle yeValve
I-spindle ye-butterfly valve ebizwa nangokuthi isiqu, isetshenziselwa ukudlulisa, ixhunywe ku-actuator noma isibambo, okulandelayo kuqhuba ngqo ukujikeleza kwepuleti le-valve, ukuze kufezwe indima yokushintsha noma yokulungisa i-butterfly valve.
1. Kusukela ezintweni: Izinto ze-spindle ngokuvamile zenziwe ngensimbi engagqwali kanye nensimbi yekhabhoni, futhi ikhodi yayo ithi: insimbi engagqwali (2cr13, 304, 316, 316L), insimbi yekhabhoni (35, 45, Q235).
2. Kusukela kwisitayela: ivalvu yevemvane edlula emgodleni (kwesobunxele) kanye nevalvu yevemvane ephindwe kabili emgodleni (kwesokudla).
a: Ngokuphathelene nentengo: i-double half-shaft ibiza kakhulu kune-through-shaft.
b: Ngokusetshenziswa: i-double half-shaft ingenza okungaphezu kwe-DN300, kanti i-through-shaft ingenza i-DN800.
c: Ukuguquguquka kwezinto ezifakwayo: izinto ezifakwa nge-shaft zingasetshenziswa kuma-valve e-butterfly aphiniwe anesilinganiso esiphansi se-scrap. Kungasetshenziswa ama-valve e-butterfly aphindwe kabili kuphela, futhi izinga le-scrap liphezulu.
d: Ukuhlanganiswa: i-through-shaft engenaphini iyindlela eyisisekelo ekwakhiweni, ukwakheka okulula, ukucutshungulwa kwe-shaft, ubunzima bokukhiqiza i-half-shaft ephindwe kabili, ngokuvamile ihlukaniswe ibe yi-upper shaft, kanye ne-lower shaft.
# 4 izingxenye ze-Butterfly valve--Isihlalo se-Valve
Isihlalo senjoloba se-soft seal butterfly valve singahlukaniswa sibe yisihlalo senjoloba esiqinile ngemuva kanye nesihlalo senjoloba esithambile emuva, kanti isihlalo se-hard seal butterfly valve ikakhulukazi siyisivalo esifanele kanye nesivalo esinamazinga amaningi.
Umehluko phakathi kwesihlalo serabha esiqinile nesinqe esithambile sevalvu yebhabhathane: isihlalo esiqinile sicindezelwa emzimbeni wevalvu ngezinto ezisusayo, ezingenakuguqulwa zodwa futhi zidinga iflange ekhethekile yevalvu yebhabhathane; isihlalo esithambile esinqe esithambile senziwe yimodeli, engashintshwa yodwa futhi ingasetshenziswa neflange engeyona ekhethekile yevalvu yebhabhathane.
Ngokuphathelene nokuphila kwesevisi yesihlalo senjoloba, impilo yesevisi yesihlalo sangemuva esithambile yinde kuneyesihlalo sangemuva esiqinile, okuyisakhiwo esikhulu esibanzi. Inqubo yokusebenza yesikhathi eside ye-valve ukuguga komgodi wesihlalo se-valve. Ukuphela komgodi wesihlalo se-valve ukuvuza ngemva kokuvuza kwamanzi esihlalo sangemuva esiqinile ngqo ngaphandle kwesenzakalo sokuvuza komzimba we-valve. Kodwa umhlane othambile awubonakali kulesi simo.
# 5 Izingxenye ze-Butterfly valve -- Indawo yokuvala
kukhona ukuvala okuthambile kanye nokuvala okuqinile,Ukukhetha izinto zokuvala ezithambile:
1、Irabha (kufaka phakathi irabha ye-butadiene, irabha ye-EPDM, njll.), esetshenziswa kakhulu kumapayipi anomfutho ophansi phezu kwamafutha namanzi.
2、Ipulasitiki (i-PTFE, i-nylon, njll.), okwengeziwe kwemidiya egqwalisayo esendleleni.
Imodi yokusebenza: isibambo, i-turbo, kagesi, umoya, i-hydraulic
Ukukhethwa kwezinto zokuvala eziqinile:
1, i-Copper alloy (yama-valve aphansi kwengcindezi)
2, insimbi engagqwali ye-Chrome (yama-valve avamile okucindezela okuphezulu nokuphakathi)
3, i-Stellite alloy (yezinga lokushisa eliphezulu kanye nama-valve anomfutho ophezulu kanye nama-valve aqinile agqwalisayo)
4, Ama-alloy asekelwe ku-nickel (wezinto ezilimazayo)
# 6 Izingxenye ze-Butterfly valve -- I-Operation Actuator
Amavalvu e-Butterfly avame ukusebenza ku-， Hand Lever， Worm Gear， Pneumatic Actuator.
Izibambo zesandla zivame ukwenziwa ngezibambo eziqinile, eziphathwe ngamakhemikhali, futhi ezimbozwe ngempuphu. Isibambo sesandla ngokuvamile sinesibambo kanye nesibambo esixhumene, sifanelekile ku-DN40-DN250.
Igiya lezibungu lifanelekela ama-valve amakhulu ezibungu. Igiya lezibungu livame ukusetshenziswa ngobukhulu obukhulu kune-DN250, kusenamabhokisi e-turbine anezigaba ezimbili kanye nezigaba ezintathu.
Ama-actuator omoya ahlukaniswe ngezigaba ezimbili, ama-actuator omoya asebenza kanye kanye nama-actuator asebenza kabili.
Ama-actuator kagesi angahlukaniswa ngezinhlobo zokujika okuningi kanye nezinhlobo zokujika kancane. Uhlobo lokujika okuningi lujika ngaphezu kuka-360° ukuvula nokuvala ivalvu kuyilapho uhlobo lokujika kancane lujika ngokuvamile ngama-90° ukuvula nokuvala ivalvu ngokugcwele.
Okulandelayo, ake sibheke ukuthi ungazihlanganisa kanjani izingxenye ze-butterfly valve
