1. Gate valve lata leng hkrang hpe sawk sagawn ai
Manual galaw ai lam a madung daw hku nna, .chyinghka valve lata lengshi a hkrang masa a majaw valve hpaw ai hte pat ai atsam hte magam bungli prat hpe hkrak hkrak hkra machyi shangun ai. Madung daw ni gaw:
| Daw ni | Magam bungli hpe sang lang dan ai |
| Lata leng hkum hkrang | Torque gaw shinggyim masha a shingjawng ai lam hku nna byin pru wa ai rai nna, diameter design gaw bungli galaw ai torque a kaba ai hpe hkrak sha hkra machyi shangun ai (diameter kaba wa yang, shakut shaja ai lam n law wa ai) |
| Valve stem matut mahkai ladat | Trapezoidal thread pair (hpaw da ai n-gang amyu) shing nrai, n-gang -in (nsin sin ai n-gang amyu) hpe hkap la nna, shinggrup ai shamu shamawt ai lam kaw nna linear shamu shamawt ai lam de galai shai wa ai hpe lu la na matu |
| Laknak pat ai jak | Buckle (sh) shara jahkrat ai pin hpe n kaja hkra galaw na matu |
2. Madung jak hpaji a npawt tara ni
1. Thread shapoi ai ladat
Trapezoidal shingnip lahkawng hkrang shapraw ai: 30℃shingnip angle trapezoidal shingnip hpe lang nna, jak rung n-gun kaba ai (70%-90% du hkra) lu la na matu
Torque htawt sit ai ladat: T=F×r=2πηW×p
(T: lata leng a n-gun, F: bungli galaw ai n-gun, r: lata leng a radius, W: chyinghka n-gun, p: n-gang n-gun, η: jak rung n-gun)
2. Hkrun lam hte tinang hkum hpe-hkap pat da ai akyu
Static friction coefficient (n-gang kaw nna magri du hkra) μ≈0.1-0.15, hpaw ngut ai hpang shi a shawng na shara de shi hkrai shi n bai wa na hpe kam shangun ai.
Tinang hkum hpe-hkap pat da ai masa: n-gang n-gang n-gang < arctanμ, law malawng gaw 5℃hta n-pu (sh) maren sha re ai hku galaw da ai
3. Arung arai hpaji hpe jai lang ai lam
| Stress amyu | Laksan manu jahpu | ninghkap ladat ni |
| Shapraw ai myit ru myit tsang lam | 80-120 MPa | ASTM A276 304 n-hprang n-gang hpe lang u |
| Shear n-gun | 45-65 MPa | N-gang npawt nhpang radius a hkrang hpe grau kaja hkra galaw u |
| Bending stress | < 50% of material yield strength | Valve stem diameter hte lata leng hpe madi shadaw ai shara ni a jahpan hpe jat ya u |
3. Laksan jai lang ai lam ni hpe sawk sagawn ai
1. Wan sau hpaga lam
Bungli galaw ai masa: n-gun kaba ai (API 20000psi), nbung katsi ai ( 425℃hta n-pu (sh) maren sha )
laksan hkrang shapraw ai lam:
Nsin sin ai rod hkrang gaw, n-gun n rawng ai hte n-gun n rawng ai hpe pat shingdang na matu
500mm hta grau kaba ai (sh) maren sha re ai diameter hpe jat ai lata leng (diameter) gaw bungli galaw ai n-gun hpe shayawm na matu
2. Mare kata na gas masa
Hkamja lam a matu ra kadawn ai lam ni:
Torque hpe shadawn sharam ai jak hte hpaw da ai ( 200N·m hta n law ai (sh) maren sha re)
Hpraw/hpraw ai sadi jaw kumla gaw kayin hkawm ai lam a matu
4. Magam bungli galaw ai lam hte gram lajang ai shara ni
1. Standard bungli galaw ladat ni
Hkum tsup ai-hpaw ai shara hpe kam ai: Ntsa de kayin ngut ai hpang, thermal jat wa ai hte jamming n byin hkra 1/2 kayin ai hpe bai nhtang wa u
N kaja ai hku hparan ai lam:
Jamming galaw ai shaloi, grai law ai torque hpe n mai galaw ai (400N hta n law ai (sh) maren sha re ngu tsun shadut da ai)
NLGI grade 2 lithium- hpe madung tawn nna sau bang na matu shata mali hta kalang gram lajang ai tsi htu ai
2.Common manghkang hparan ai lam
| Mara byin ai lam | Hpaji masa hku nna ninghkap ai lam ni |
| Lata leng n shamu shamawt ai | Valve npawt nhpang n-gang lahkawng a n-gun yawm mat ai hpe jep yu u (0.3mm hta n-pu (sh) maren sha ahkang jaw da ai shara) |
| Hpaw ai hte pat ai torque akajawng sha jat wa ai . | Valve n-gup kata na scale hpe jasan jaseng u (sh) packing seal 2 hpe galai kau u. |
5. Industry case ni hte hpaji hparat ningnan ni hpe .
Hpa majaw nga yang, n-gun madun ai lam galaw ai.
Ndai company gaw, lata hte galaw ai jak amyu myu hpe hpaji rawng ai hku galaw shapraw nna dut shabra ai company langai re. 2002 ning hta hpaw hpang wa ai rai nna, Hangzhou mare, Xiaoshan ginwang, Jinhua mare, Fenghuangshan kahtawng kaw ginjaw garan rung nga ai rai nna, Hangzhou Xiaoshan mungkan nbungli pa kaw nna mawdaw hte minit 30 daram sha hkawm ra ai shara kaw nga ai.
Anhte a company a madung galaw shapraw ai arung arai ni gaw, n-gun n rawng ai n-gang n-gang, welding n-gang, stamping n-gang, aluminum alloy n-gang ni rai nna, dai aten hta sha, n-gang a galu kaba ai, hkrang, nsam, ntsa lam hpe gram lajang ai, logo, etc. ni hpe mung, customer ni ra sharawng ai hku nna, gram lajang mai ai.
Laksan jai lang mai ai lam ni:
Anhte a lata hte lang ai jak ni gaw, valve, pump, reactor, mixer, hka chyinghka, generator zawn re ai arung arai law law hta grai law hkra jai lang nga ai. Shanhte a kam hpa mai ai bungli galaw ai lam gaw, application amyu myu hta n-gun n rawng ai sha bungli galaw lu hkra galaw ya nna, ahkyak ai jak ni a akyu rawng ai lam hte bungli galaw lu ai atsam hpe madi shadaw ya ai.
-Sumla hkrung galaw ai shara ni a Mungdaw-:
Ya aten na galaw shapraw ai arung arai ni hte hpring tsup ai anhte a company gaw, rawt jat galu kaba wa ai jak rung ni hte hpaji masa ni hpe gumrawng nga ai. CNC lathes, milling jak, htu jak, welding jak, polishing jak, coating jak ni hte kaga ni gaw, shingdaw n lu ai atsam hte hkrak ai lata leng ni hpe jaw ya lu ai arung arai ni a laknak ni hpe hpaw shabawn da ai.
6. Htawm hpang na rawt jat galu kaba lam hpe tau hkrau tsun dan ai
Hpaji rawng ai hku gram lajang ai lam: hpawng de da ai torque sensor + wireless shapoi ai module (2026 hta 30% jan shang wa na ngu sawn la ai)
Arung arai hpaji ningnan:
Carbon fiber hte galaw da ai lata leng (60% shayawm ai
Tinang hkum tinang - sau chya ya ai ceramic hte ka-up da ai sumri lahkawng
Hpaga lam hpe yu ai lam: API 6D-2024 madang nnan hpe hkan sa ai hte rau, ergonomic hkrang shapraw ai lam hte jak rung bungli galaw ai lam ni hpe
kaja dik htum galaw aichyinghka valve lata leng nihpaji masa shingjawng ai lam a madung shara tai wa na re. Mungkan ting na gat lawk gaw shaning shagu 2019 ning hta rawt jat wa na hpe myit mada da ai.
2025 kaw nna 2030 du hkra 6.8% rai na re.
