Ivalvu yokusika ikwabizwa ngokuba yivalvu yokusika. Yeyona valve isetyenziswa kakhulu. Isizathu sokuba ithandwe kukuba ukungqubana phakathi kweendawo zokuvala ngexesha lenkqubo yokuvula nokuvala kuncinci, ihlala ixesha elide, ukuphakama kokuvula akukukhulu, ukwenziwa kwayo kulula, kwaye ukugcinwa kwayo kulula. Ayifanelekanga kuphela kuxinzelelo oluphakathi noluphantsi, kodwa ikwafanelekile nakuxinzelelo oluphezulu.
Umgaqo wokuvala wevalvu yeglobhu kukuxhomekeka kuxinzelelo lwesiqu sevalvu ukwenza umphezulu wokutywina wediski kunye nomphezulu wokutywina wesihlalo sevalvu zilingane kakuhle ukuthintela ukuba i-medium ingahambi.
Ivalvu yokuvala ivumela kuphela i-medium ukuba ihambe kwicala elinye kwaye ibhekisa kwicala elinye xa ifakiwe. Ubude besakhiwo sevalvu yokuvala bude kunobo bevalvu yesango, kwaye ukumelana kolwelo kukhulu, kwaye ukuthembeka kokutywina akunamandla ngexesha lokusebenza ixesha elide.
Kukho iintlobo ezintathu zeevalvu zeglobhu: iivalvu zeglobhu ezithe tye, iivalvu zeglobhu ezikwi-engile yasekunene kunye neevalvu zeglobhu ezigobileyo ezihamba ngqo.
Eyona nzuzo icacileyo kukuba ngexesha lenkqubo yokuvula nokuvala, ukungqubana phakathi kwediski nomphezulu wokuvala umzimba wevalvu kuncinci kunokwevalvu yesango, ngoko ke ayigugi. Ukuphakama kokuvula ngokubanzi yi-1/4 kuphela yobubanzi bendlela yesihlalo sevalvu, ngoko ke incinci kakhulu kunevalvu yesango. Ngokwesiqhelo kukho umphezulu omnye wokuvala emzimbeni wevalvu kunye neflaphu yevalvu, ngoko ke inkqubo yokuvelisa ilungile kwaye kulula ukuyigcina.
Uxinzelelo oluqhelekileyo okanye inqanaba loxinzelelo lwevalvu yokumisa: PN1.0-16.0MPa, ANSI CLASS150-900, JIS 10-20K, ububanzi okanye i-caliber eqhelekileyo: DN10~500, NPS 1/2~36″, indlela yokudibanisa ivalvu yokumisa: iflange, i-Butt welding, umsonto, njl.njl., ubushushu obufanelekileyo: -196℃~700℃, imo yokuqhuba ivalvu yokumisa: ngesandla, i-bevel gear drive, i-pneumatic, electric, hydraulic, i-gas-liquid linkage, i-electro-hydraulic linkage, izinto zomzimba wevalvu: WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8 (304), CF3 (304L), CF8M (316), CF3M (316L), Ti. Izixhobo ezahlukeneyo zisetyenziselwa ivalvu yokumisa, enokusetyenziselwa amanzi, umphunga, ioyile, i-nitric acid, i-acetic acid, kunye ne-oxidizing media. , iUrea kunye nezinye izixhobo zokusasaza.
INortech ngomnye wabavelisi beevalvu zoshishino abaphambili eTshayina abanesiqinisekiso somgangatho se-ISO9001.
Iimveliso eziphambili:Ivalvu yebhabhathane,Ivalvu yeBhola,Ivalvu yeSango,Jonga iValve,IGlobe Vavlve,Ii-Y-Strainers,Isixhobo sombane,Ii-Acurators ze-Pneumatic.
