I-Zhongfa Valve ngumvelisi ochwephesha weendawo zevalvu yebhabhathane kunye neevalvu zebhabhathane, eyasekwa ngo-2006, ibonelela ngeemveliso zeevalvu kunye neemveliso zeenxalenye zevalvu yebhabhathane kumazwe angaphezu kwama-20 emhlabeni, ngokulandelayo, i-Zhongfa Valve iza kuqalisa ukwazisa ngokweenkcukacha iindawo zevalvu yebhabhathane.
Ivalvu yebhabhathane inala macandelo alandelayo, amagama eendawo zebhabhathane ngumzimba wevalvu, iDisiki yevalvu, umngxuma wevalvu, isihlalo sevalvu, umphezulu wokutywina, kunye ne-actuator yokusebenza, ngoku, siza kwazisa la macandelo evalvu yebhabhathane nganye nganye.
# 1 Iindawo zevalvu yebhabhathane--Umzimba wevalvu
Sixoxa ngomzimba wevalvu ngokubhekiselele kuqhagamshelo kunye nezinto ezisetyenziswayo
1. Ngokubanzi, ngokweendlela ezahlukeneyo zokudibanisa, iivalvu zebhabhathane zinohlobo lweflange, uhlobo lwewafer, kunye nohlobo lwelug, kwaye iindlela eziqikelelweyo ziboniswe kumfanekiso. Kuhlobo ngalunye lokudibanisa, kukho umahluko omncinci ngokweemold ezahlukeneyo, njengakwivalvu yebhabhathane yewafer, iZhongfa Valve ineemold ezilandelayo eziqhelekileyo.
2. Ngokwezinto eziphathekayo, ezixhaphakileyo ngumzimba wesinyithi othambileyo, umzimba wesinyithi sekhabhoni, umzimba wesinyithi esingenasici, umzimba wobhedu, kunye nomzimba wesinyithi ophindwe kabini.
# 2Iindawo zevalvu yebhabhathane--Idiski yeValve
Indlela yediski yevalvu nayo iyahluka, idiski yepin, idiski engenazipin, idiski enerabha, iDisk eneNylon, iDiski eneElectroplated, njalo njalo, Ngokwesiqhelo, idiski yevalvu ikhethwa ngokweemeko zokusebenza kunye nomgangatho.
Kwidiski engenazikhonkwane, kukho umngxuma odlulayo kunye nomngxuma ophindwe kabini, idiski engenazikhonkwane iya kunciphisa umngcipheko wamathuba okuvuza, kwiDiski enezikhonkwane, kusenokwenzeka ukuba iphini igugile okanye igqwalile emva kwexesha elide, imidiya evela kwiphini kwidiski leyo ivula umngxuma. Singathanda ukukhetha idiski engenazikhonkwane kumthengi wethu.
# 3 Iindawo zevalvu yebhabhathane--I-Valve Spindle
I-spindle ye-butterfly valve ekwabizwa ngokuba yi-stem, isetyenziselwa ukudlulisa, iqhagamshelwe kwi-actuator okanye kwi-handle, oku kulandelayo kuqhuba ngqo ukujikeleza kwe-valve plate, ukuze kufezekiswe utshintsho lwe-butterfly valve okanye indima yohlengahlengiso.
1. Kwizinto ezisetyenzisiweyo: Izinto ezidityanisiweyo zenziwe ngentsimbi engagqwaliyo kunye nentsimbi yekhabhoni, kwaye ikhowudi yazo yile: intsimbi engagqwaliyo (2cr13, 304, 316, 316L), intsimbi yekhabhoni (35, 45, Q235).
2. Ukusuka kwisitayile: ivalvu yebhabhathane edlula kwishafti (ekhohlo) kunye nevalvu yebhabhathane ephindwe kabini ishafti (ekunene).
a: Ngokwexabiso: i-double half-shaft ibiza kakhulu kune-through-shaft.
b: Ngokuphathelele ukusetyenziswa: i-double half-shaft inokwenza okungaphezulu kwe-DN300, kwaye i-through-shaft ingenza i-DN800.
c: Ukuguquguquka kwezinto ezifakelwayo: izixhobo ezisebenzisa i-through-shaft zingasetyenziswa kwiivalvu zebhabhathane ezifakwe i-pined ezinesantya esiphantsi sokukrazula. Kusetyenziswa iivalvu zebhabhathane eziphindwe kabini kuphela, kwaye isantya sokukrazula siphezulu.
d: Ukuhlanganisa: i-through-shaft ngaphandle kwe-pin yindlela esisiseko kuyilo, uyilo olulula, ukucutshungulwa kwe-shaft, ubunzima bokuvelisa i-half-shaft ephindwe kabini, ngokubanzi yahlulwe kwi-shaft ephezulu, kunye ne-shaft esezantsi.
# 4 Iindawo zevalvu yebhabhathane--Isihlalo seValve
Isihlalo serabha sevalvu yebhabhathane ethambileyo singahlulwahlulwa sibe sisihlalo serabha esiqinileyo kunye nesihlalo serabha esithambileyo, kwaye isihlalo sevalvu yebhabhathane elukhuni ikakhulu sisitywino esifanelekileyo kunye nesitywino esinamanqanaba amaninzi.
Umahluko phakathi kwesihlalo serabha esiqinileyo nesisihlalo serabha esithambileyo sevalvu yebhabhathane: isihlalo esiqinileyo sicinezelwa emzimbeni wevalvu ngee-abrasives, ezingenakutshintshwa zodwa kwaye zifuna iflange ekhethekileyo yevalvu yebhabhathane; isihlalo esithambileyo senziwe yimodeli, enokutshintshwa zodwa kwaye ingasetyenziswa neflange engeyonto ikhethekileyo kwivalvu yebhabhathane.
Ngokuphathelele ubomi benkonzo yesihlalo serabha, ubomi benkonzo yesihlalo esithambileyo esingasemva bude kunesesihlalo esiqinileyo esingasemva, esisakhiwo esikhulu esibanzi. Inkqubo yokusebenza kwexesha elide yevalvu, isiphelo sevalvu, ukuwohloka kwesiphelo sevalvu. Isiphelo sevalvu sesihlalo, ukuvuza emva kokuba amanzi esihlalo esiqinileyo esingasemva ephuma ngqo ngaphandle kwento yokuvuza komzimba wevalvu. Kodwa umqolo othambileyo awubonakali kule meko.
# 5 Iindawo zevalvu yebhabhathane--Umphezulu wokutywina
kukho ukutywina okuthambileyo kunye nokutywina okuqinileyo,Ukukhetha izinto zokutywina ezithambileyo:
1、Irabha (kubandakanya irabha ye-butadiene, irabha ye-EPDM, njl.njl.), isetyenziswa kakhulu kwimibhobho enoxinzelelo oluphantsi phezu kweoyile namanzi.
2、Iplastiki (i-PTFE, i-nylon, njl.njl.), engaphezulu kweendaba ezirhabaxa ezisendleleni.
Imo yokusebenza: isiphatho, i-turbo, umbane, umoya, i-hydraulic
Ukukhethwa kwezinto zokutywina eziqinileyo:
1, i-Copper alloy (yeevalvu eziphantsi koxinzelelo)
2, intsimbi engatyiwayo ye-Chrome (yeevalvu zoxinzelelo oluphezulu noluphakathi)
3, i-Stellite alloy (yeevalvu zobushushu obuphezulu kunye noxinzelelo oluphezulu kunye neevalvu ezinamandla ezirhabaxa)
4, ii-alloys ezisekelwe kwi-nickel (zeendaba ezirhabaxa)
# 6 Iinxalenye zevalvu yebhabhathane--Isixhobo sokuSebenza
Iivalvu zebhabhathane zihlala zisebenza kwezi zilandelayo, i-Hand Lever, i-Worm Gear, i-Pneumatic Actuator.
Izikhonkwane zesandla zihlala zenziwe ngokuqina, zicocwe ngamakhemikhali, kwaye zigqunywe ngomgubo. Isikhonkwane sesandla sidla ngokuba nesiphatho kunye nesikhonkwane esidibanisayo, sifanelekile kwi-DN40-DN250.
Isixhobo seempethu sifanelekile kwiivalvu ezinkulu zebhabhathane. Isixhobo seempethu sidla ngokusetyenziselwa ubukhulu obungaphezulu kwe-DN250, kusekho iibhokisi ze-turbine ezinamanqanaba amabini kunye namanqanaba amathathu.
Ii-actuators ze-pneumatic zahlulwe zibe ziindidi ezimbini, ii-actuators ze-pneumatic ezisebenza ngombane omnye kunye nee-actuators ze-pneumatic ezisebenza kabini.
Ii-actuator zombane zinokwahlulwa zibe ziintlobo ezijika-jika ezininzi kunye neentlobo ezijika-jika kancinci. Uhlobo olujika-jika kakhulu lujika ngaphezu kwama-360° ukuvula nokuvala ivalvu ngelixa uhlobo olujika-jika kancinci lujika ngokuqhelekileyo kuma-90° ukuvula nokuvala ngokupheleleyo ivalvu.
Okulandelayo, makhe sijonge indlela yokufaka iindawo zevalvu yebhabhathane kunye
