I-Zhongfa Valve ngumvelisi ochwepheshile wamalungu evalve yebhabhathane kunye neevalvu zebhabhathane, esekwe ngo-2006, ebonelela ngeevalvu kunye neemveliso zevalve yebhabhathane kumazwe angaphezu kwama-20 kwihlabathi, ngokulandelayo, iZhongfa Valve iya kusungula isingeniso esineenkcukacha samalungu evalve yebhabhathane.
Ivalve yebhabhathane inala malungu alandelayo, igama lamalungu ebhabhathane ngumzimba wevalvu, iDiskhi yevalve, ishafti yevalvu, isitulo sevalvu, indawo yokutywina, kunye ne actuator yokusebenza, ngoku, siyakwazisa la malungu evalve yebhabhathane nganye nganye.
# 1 Amalungu evalvu yebhabhathane--Umzimba wevalvu
Sixoxa ngomzimba we-valve malunga nokudibanisa kunye nezinto eziphathekayo
1. Ngokuqhelekileyo, ngokweendlela ezahlukeneyo zokudibanisa, iivalve zebhabhathane zinohlobo lwe-flange, uhlobo lwe-wafer, kunye nohlobo lwe-lug, kwaye izitayela eziqikelelweyo ziboniswa kumfanekiso.Kuhlobo ngalunye loqhagamshelo, kukho iiyantlukwano ezifihlakeleyo ngokwemibumbo eyahlukeneyo, njengevalve yebhabhathane lebhabhathane, iValve yaseZhongfa inomngundo oqhelekileyo olandelayo.
2. Ngokwezinto eziphathekayo, eziqhelekileyo ziyi-ductile iron body, i-carbon steel body, i-stainless steel body, i-brass body, kunye ne-super duplex yensimbi.
#2Amalungu evalvu yebhabhathane--I-Valve Disc
Isitayela se-disc ye-valve iyahluka, i-disc ye-pin, i-disc ye-pinless, i-disc ene-rubber, i-Disc ene-Nylon, i-Electroplated Disc, njalo njalo, Ngokuqhelekileyo, i-disc ye-valve ikhethwe ngokwemiqathango yokusebenza kunye nephakathi.
Kwidiskhi engenaphini, kukho i-shaft edlulayo kunye ne-half half shaft, i-disc ngaphandle kwe-pin iyakunciphisa umngcipheko wamathuba okuvuza, kwi-Disc ene-pin, kunokwenzeka ukuba i-pin igugile okanye igqwalile emva kwexesha elide. media ukusuka isikhonkwane kwi disc ukuba ukuvuza umngxuma shaft.Singathanda ukukhetha icwecwe lecwecwe lomthengi wethu.
# 3 Amalungu evalvu yebhabhathane--Ivalve Spindle
Ivalve yebhabhathane yokuphotha ikwabizwa ngokuba sisikhondo, isetyenziselwa ukusasaza, iqhagamshelwe kwi-actuator okanye umqheba, oku kulandelayo kuqhuba ngokuthe ngqo ukujikeleza kwepleyiti yevalve, ukuze kufezekiswe iswitshi yevalve yebhabhathane okanye indima yohlengahlengiso.
1. Ukususela kwizinto eziphathekayo: Isixhobo se-spindle ngokuqhelekileyo senziwe ngensimbi engenasici kunye ne-carbon steel, kwaye ikhowudi yayo yile: insimbi engenasici (2cr13, 304, 316, 316L), i-carbon steel (35, 45, Q235).
2. Ukusuka kwisitayile: ivalve yebhabhathane kwishaft (ekhohlo) kunye nevalve yebhabhathane ephindwe kabini kwishafti (ekunene).
a: Ngokwexabiso: i-half-shaft ephindwe kabini ibiza kakhulu kune-shaft-shaft.
b: Ngokwemigaqo yokusetyenziswa: i-half-half-shaft ingenza ngaphezu kwe-DN300, kunye ne-shaft-shaft ingenza i-DN800.
c: Ufakelo oluguquguqukayo: izifakelo ze- through-shaft zingasetyenziswa kwiivalvu zebhabhathane eziphiniweyo ezinesantya esiphantsi sokulahlwa.Kuphela iivalve zebhabhathane eziphindwe kabini ze-semi-shaft ezinokusetyenziswa, kwaye izinga lokulahlwa liphezulu.
d: INdibano: i-shaft-shaft ngaphandle kwephini yindlela esisiseko kuyilo, uyilo olulula, ukusetyenzwa kwe-shaft, ubunzima bokuvelisa i-half-half-shaft, ngokubanzi yahlulahlulwe kwi-shaft ephezulu, kunye ne-shaft ephantsi.
# 4 Amalungu evalvu yebhabhathane--Isitulo seValve
Isihlalo serabha sevalve yebhabhathane ethambileyo sinokwahlulwa sibe sisitulo serabha esingasemva kunye nesihlalo serabha esithambileyo esingasemva, kwaye isihlalo sevalve yebhabhathane eqinile sitywina ngokufanelekileyo kunye nokutywinwa kwamanqanaba amaninzi.
Umahluko phakathi kwesihlalo serabha esinomqolo oqinileyo kunye nesihlalo serubha esithambileyo sevalve yebhabhathane: isihlalo esine-butterfly sicinezelwe kumzimba wevalve ngama-abrasives, angenakutshintshwa ngokwawo kwaye afune i-flange ekhethekileyo yevalve yebhabhathane. ;isihlalo esine-soft-backed senziwa yimodeli, enokuthi ithathelwe indawo ngokwayo kwaye ingasetyenziselwa i-flange engekho ekhethekileyo kwi-valve butterfly.
Ngokubhekiselele kubomi benkonzo yesihlalo serabha, ubomi benkonzo yesitulo sangasemva esithambileyo bude kunobo besitulo sangasemva esilukhuni, esisisakhiwo esikhulu esibanzi.Ivalve yexesha elide yokusebenza kwenkqubo yevalvu yesitulo sesitulo sokunxitywa kweshaft ekupheleni.Ukuvuza kweshafti yesihlalo sevalvu emva kokuvuza kwamanzi kwesitulo sangasemva esiqinileyo ukuya ngqo kumphandle wento evuzayo yomzimba wevalvu.Kodwa umqolo othambileyo awubonakali kule meko.
# 5 Amalungu evalvu yebhabhathane--Umphezulu wokutywina
kukho ukutywinwa okuthambileyo kunye nokutywinwa okuqinileyo,Ukukhethwa kwezinto ezithambileyo zokutywina:
I-1, Irabha (kubandakanywa irabha ye-butadiene, irabha ye-EPDM, njl.), isetyenziswa kakhulu kwimibhobho yoxinzelelo oluphantsi phezu kweoli kunye namanzi.
I-2, iPlastiki (i-PTFE, inayiloni, njl.), ngakumbi kumajelo eendaba ezonakalisayo kumbhobho.
Imowudi yokusebenza: ukubamba, i-turbo, umbane, i-pneumatic, i-hydraulic
Ukukhethwa kwezinto eziqinileyo zokutywina:
1, i-alloy yobhedu (yeevalvu zoxinzelelo oluphantsi)
2, Chrome steel stainless (kwivalufa eqhelekileyo eliphezulu naphakathi uxinzelelo)
3、 Ingxubevange yeStellite (yeqondo lobushushu eliphakamileyo kunye neevalvu zoxinzelelo oluphezulu kunye neevalvu ezomeleleyo ezidlekayo)
4, ii-alloys ezisekwe kwi-nickel (kwimithombo yeendaba ezonakalisayo)
# 6 Amalungu evalvu yebhabhathane--Isixhobo sokuSebenza
Iivalve zebhabhathane zidla ngokusebenza koku kulandelayo, Isixhobo sesandla, isiXhobo seNtshulube, Isixhobo sokusebenza somoya.
Iintambo zezandla zihlala zenziwe ngokungqongqo, ziphathwe ngamachiza, kwaye zigqunywe ngumgubo.I-lever yesandla ngokuqhelekileyo iqulethe i-handle kunye ne-interlocking lever, Ifanelekile kwi-DN40-DN250.
Isixhobo se-worms sifanelekile kwiivalve ezinkulu zebhabhathane.Ibhokisi yegiya yeentshulube idla ngokusetyenziselwa ubungakanani obukhulu kune-DN250, kusekho iibhokisi zeinjini ye turbine enamanqanaba amabini kunye namanqanaba amathathu.
Ii-activators ze-pneumatic zohlulwe zibe ziindidi ezimbini, i-single-acting kunye ne-double-acting pneumatic actuators.
Ii-actuator zombane zinokwahlulwa zibe ziindidi zokujika ezininzi kunye neentlobo ze-part-turn.Uhlobo lwe-Multi-turn lujika ngaphezu kwe-360 ° ukuvula nokuvala ivalve ngelixa uhlobo lwe-part-turn lujika ngokuqhelekileyo i-90 ° ukuvula nokuvala ngokupheleleyo ivalve.
Okulandelayo, makhe sijonge indlela yokufaka iinxalenye zevalve yebhabhathane kunye
