1. Dakunw ka bololabɔcogo sɛgɛsɛgɛli .
I n’a fɔ bolola baarakɛcogo kolomayɔrɔ, .Gate valve main .A bɛ nɔ tilennen bila sumanw dabɔli ni u datugucogo ɲuman na ani baarakɛcogo la k’a sababu kɛ a jɔcogo ye. A yɔrɔ kolomaw ye:
| Yɔrɔw . | Baarakɛcogo ɲɛfɔli . |
| bolokɔni farikolo . | Torque bɛ sɔrɔ hadamaden ka wulili fɛ, wa a cɛmancɛ dilancogo bɛ nɔ bila baara girinya hakɛ la (ni a cɛmancɛ ka bon, a ka cɛsiri ka dɔgɔ) |
| Valve stem ɲɔgɔndan fɛɛrɛ . | Adopt trapezoidal thread pair (da wulilen suguya) walima a jɔlen-in thread (dibi bere suguya) walasa ka se ka fɛn caman tigɛli sɔrɔ ka bɔ jiginni lamagacogo la ka taa lamagacogo tilennen na |
| locking minɛn . | Buckle walima positionnement pin dilancogo walasa ka misopération bali . |
2. Core Mechanics Mechanics sariyakolow .
1. Thread transmission mechanics .
Trapezoidal thread pair design: ka baara kɛ ni 30 degre jiri angle trapezoidal ye walasa ka se ka masinw ka baarakɛcogo ɲuman sɔrɔ (ka se 70%-90%)
Formula torque de transfert : t{0}}f×R{=2πηW×p .
(T: Bololabaarakɛminɛn, F: Baarakɛcogo fanga, R: Bololabaarakɛminɛn, W: Dala doni, P: Filɛlikɛlan, η: masinko nafa)
2. Friction ani yɛrɛ-Locking effect .
Static Friction Coefficient (Steel to Bronze) μ≈0.1-0.15, k’a lajɛ ko a tɛna segin a cogo kɔrɔ la a yɛrɛma da wulilen kɔfɛ .
Yɛrɛ-Locking Condition: Thread lead angle < arctanμ, a ka c’a la, a bɛ dilan ka dɔgɔn walima a bɛ bɛn degere 5 ma .
3. Materiel mechanics (Mekanikiw) waleyali .
| Degun suguya . | typical value range . | countermeasures . |
| Extrusion stress . | 80-120 MPa . | Baara kɛ ni ASTM A276 304 inox ye . |
| shear stress . | 45-65 MPA . | Optimiser de la design de la fillet root root radius . |
| Kɔrɔtɔli degun . | < 50% of material yield strength | Aw bɛ dɔ fara sumanw jiribolo janya kan ani bolokɔniw dɛmɛyɔrɔw hakɛ . |
3. Sɛgɛsɛgɛli kɛra baarakɛcogo misaliw kan .
1. Petrokimika baarakɛlaw .
Baarakɛcogo : tansiyɔn jiginni (API 20000PSI), funteni caman ( a ka dɔgɔ walima a bɛ bɛn degere 425 ma ) .

2.Gɛlɛyaw ɲɛnabɔli min bɛ kɛ ɲɔgɔn fɛ .
| Fault fenomenon . | Teknikiw ka fɛɛrɛw . |
| Bololabaarakɛlaw ka wuluwulu . | Aw bɛ a lajɛ ni valve stem thread pair (a bɛ se ka kɛ 0,3mm ye min ka dɔgɔn walima ni a bɛ bɛn 0,3mm ma) . |
| Dakabanɔgɔ ni dadon torque barika bɛ bonya . | Aw bɛ balansi saniya sumanmugu kɔnɔ walima ka pake sigilan 2 falen . |
