Ivalve yebhola njengohlobo oluqhelekileyo lwevalve, inoluhlu olubanzi lwezicelo kwiindawo ezininzi. Ke, zeziphi iintlobo zeevalvu zebhola? Eli nqaku liza kukunika intshayelelo eneenkcukacha kwiintlobo ezahlukeneyo zeevalvu zebhola ukukunceda uqonde ngcono kwaye ukhethe iimveliso zevalve yebhola.
1. Isishwankathelo seevalvu zebhola
I-valve yebhola yibhola njengeendawo zokuvula kunye nokuvala i-valve, isakhiwo sayo esilula, ukusebenza okulula, ukusebenza kakuhle kokutywinwa, kusetyenziswe ngokubanzi kwi-petroleum, imichiza, igesi yendalo, unyango lwamanzi kunye nezinye iindawo zoshishino. Iivalve zebhola zinokukhethwa ngokweemfuno ezahlukeneyo kunye neemeko zesicelo.
Ababini, uhlobo kunye neempawu zevalve yebhola yaseChina
1. Ukuhlelwa ngokwemathiriyeli:
(1) I-valve yebhola ye-Carbon steel: ubukhulu becala yenziwe nge-carbon steel material, enokumelana noxinzelelo oluphezulu, amandla alungileyo, ukuxhatshazwa kokugqoka kunye nezinye iimpawu, ezifanelekileyo kwintsimi yoshishino jikelele yenkqubo yokulawula umbhobho.
(2) I-valve yebhola yensimbi engenasici: yenziwe ngezinto zensimbi ezingenasici, ezinokumelana ne-corrosion efanelekileyo, ilungele imidiya ephazamisayo kunye neemfuno zokucoceka kwizihlandlo eziphezulu.

2. Ngohlobo loqhagamshelwano:
(1) Ivalve yebhola enemisonto: uqhagamshelo olunentambo, kulula ukuyifaka, ilungele imibhobho edayamitha encinci kunye nezixhobo.
(2) Ivalve yebhola yeflange: ngoqhagamshelo lweflange, ukusebenza kakuhle kokutywina, ilungele imibhobho emikhulu yobukhulu kunye nezixhobo.
(3) I-valve yebhola ye-Welding: Ngokudibanisa i-welding, ngamandla amakhulu kunye nokusebenza kokutywinwa, okufanelekileyo kubushushu obuphezulu, uxinzelelo oluphezulu kunye nezinye izihlandlo ezikhethekileyo.
3. Ukuhlelwa ngokwesakhiwo:
(1) Ivalve yebhola edadayo: uqhagamshelo oludadayo phakathi kwebhola kunye nesiqu sevalve, kunye nokusebenza kakuhle kokutywina kunye nokunganyangeki.
(2) I-valve yebhola esisigxina: uxhulumaniso olusisigxina phakathi kwebhola kunye ne-valve stem, ukusebenza okuzinzileyo, okufanelekileyo kuxinzelelo oluphezulu, ukushisa okuphezulu kunye nezinye iziganeko ezikhethekileyo.
(3) I-valve yebhola yombane: Ngesixhobo sombane sokuqhuba i-valve yebhola yokuvula nokuvala, ukufezekisa ulawulo olukude kunye nokusebenza ngokuzenzekelayo.
(4) I-valve yebhola ye-pneumatic: Ngesixhobo se-pneumatic ukuqhuba i-valve yebhola yokuvula nokuvala, ukufezekisa ulawulo olukude kunye nokusebenza ngokuzenzekelayo.
4. Ukuhlelwa ngokwemigaqo yokusebenza:
(1) Ivalve yebhola eyenziwe ngesandla: Ngokusebenzisa isikhondo sevalve ngesandla, ibhola ihla inyuka ilawule ukucinywa kwesiphakathi.
(2) Ivalve yebhola yombane: amandla avuliwe, ngenjini yokuqhubela isikhondo sevalve, ukuphumeza intshukumo yebhola enyukayo nasezantsi, ukulawula nokuvala imidiya.
(3) Ivalve yebhola yepneumatic: ngomthombo womoya ukuqhuba isilinda, ukufikelela phezulu nasezantsi intshukumo yesikhondo sevalve, lawula ibhola uyivule nayivale.
Iii. Ukuqukumbela
Kukho iintlobo ezininziiivalve zebhola eTshayina, kunye nokukhethwa kwevalve yebhola echanekileyo kufuneka kuthathelwe ingqalelo ngokweemeko ezithile kunye neemfuno. Ukuqonda iintlobo ezahlukeneyo zeevalve zebhola kunceda ukukhetha ngcono iimveliso ezifanelekileyo, ukuze ufezekise umphumo wokusetyenziswa. Ndiyathemba ukuba eli nqaku lingakunika ireferensi eluncedo xa ukhetha ivalve yebhola.
