Manual valve hpe shara kaw galaw ai ladat hpe hpaw shadan dan ai
Manual valve hpe hpaw nna pat ai:
1. Manual valve hpe grau nna lang ai valve re. Shi a lata n-gang (sh) lata hpe shinggrup da ai n-gun hte ra kadawn ai pat da ai n-gun hpe myit sawn sumru let, shinggyim masha ni a n-gun hte maren galaw da ai. Dai majaw, galu ai lever (sh) galu ai wrench hpe lang nna shamu shamawt na matu n mai galaw ai. Nkau mi gaw wrench lang chye ai majaw, n-gun grai n lang na matu sadi ra ai, n rai yang, sealing ntsa hpe hkra machyi na matu loi ai, shing nrai, lata n-gang hte lata hpe daw kau na matu loi ai.
2. Valve hpe hpaw nna pat ai shaloi, n-gun n hkrat ai sha, ngang grin nga ra ai. Hkrun lam hpaw nna pat ai high-pressure valve ni a daw nkau mi gaw ndai hkrat sum ai n-gun gaw general valve ni hte n mai bung ai ngu sawn la ma ai.
3. Hpa majaw nga yang, n hpaw shi yang, shawng -katsi nna, hka lim mat ai hpe shaw kau ra ai. Hpaw ai shaloi, hka n-gun n rawng hkra mai byin ai daram n-gun n rawng hkra galaw ra ai.
4. Valve hpe tup hkrak hpaw ngut ai hpang, n-gun n rawng hkra, n-gun n rawng hkra, n-gang ni hpe ngang ngang jum da na matu, lata n-gang hpe npu de shinggrup ra ai. Rising stem valve ni a matu, hpaw ai shaloi ntsa dead center hpe n hkra hkra, valve stem shara ni hpe hkum tsup hkra hpaw ai hte hkum tsup ai hku pat da ai hpe dum ra ai. Bai nna, hkum tsup hkra pat da ai shaloi, n kaja ai kun ngu ai hpe jep yu na matu mung shim lum ai. Valve stem hkrat mat ai rai yang, shing nrai, valve core seal lapran hta nlung kaba ni bang mat yang, valve stem hpe tup hkrak pat kau ai shaloi, dai shara gaw galai mat na re.
5. Pipeline hpe shawng lang ai shaloi, kata na nhprang arai ni law law nga ai. Valve hpe loi mi hpaw nna, medium a high-speed flow hpe lang nna kashin kau mai ai, dai hpang, shim lum ai hku pat kau mai ai (sealing surface hpe ngam ai awu asin ni hpe n hkra hkra, lawan ai hku n rai, n-gun ja ai hku n galaw ai ), bai hpaw nna, ndai hku kalang lang bai galaw nna, n san seng ai hpe hka ja kau nna, normal work de shang wa mai ai.
6. Kaja wa hpaw da ai valve a matu, sealing ntsa kaw n san seng ai lam ni nga chye ai. Dai hpe pat kau ai shaloi, lawu na- tsun da ai ladat hpe lang nna, san seng hkra hka shin kau nna, formal hku nna ngang ngang pat da u.
7. Lata leng hte lata n-gang ni hkrat sum mat ai (sh) sum mat ai rai yang, kalang ta n-gun rawng ai shingnip hte n mai galai ai, valve stem hpe hkra machyi ai, hpaw ai hte pat ai n-gun n rawng ai majaw, galaw shapraw ai shaloi accident byin wa na hpe koi lu na matu.
8. Media nkau mi gaw valve hpe pat kau ngut ai hpang katsi mat nna valve hpe shinggrup kau ai. Operator wa gaw, sealing ntsa hta n-gun n rawng hkra, aten dep bai pat kau ra ai. N rai yang, dai medium gaw hka htung ni hku nna lawan ai hku lwi wa nna, loi loi hte htum mat na re. Sealing galaw ai ntsa.
9. Operation galaw ai shaloi, operation galaw ai shaloi grai shakut ra ai hpe mu yang, hpa majaw byin ai hpe sawk sagawn ra ai. Packing grai n-gun ja ai rai yang, atsawm sha hpaw mai ai. Valve stem skew byin mat yang, gram lajang na matu, magam gun ni hpe tsun dan ra ai. Rai sa, pat da ai masa hta, pat da ai daw gaw katsi nna jat wa ai majaw, hpaw na matu yak hkak wa ai; ndai aten hta hpaw ra ai rai yang, valve n-gang ntsa na n-gun hpe yeng seng kau lu na matu, valve shingnip hpe shinggrup ai daw mi kaw nna langai lang shinggrup ai de hpaw kau nna, dai hpang lata n-gang hpe shamu shamawt mai ai.
On-site valve ni a matu sadi maja ra ai lam ni:
1. 200℃jan ai nbung katsi ai lam , hpa majaw nga yang, nbung katsi ai aten hta nbung katsi ai aten hta nga ai, nbung katsi ai aten hta nbung katsi ai shara rawt wa ai, bolt hpe jat wa na matu katsi ai, gap jat wa ai majaw, bai shinggrup ra ai, dai hpe "thermal tightening" ngu shamying ma ai. Operator wa gaw ndai bungli hpe myit maju jung ra ai. N rai yang, hka lim ai lam loi loi hte byin wa na re.
2. Nbung laru katsi ai aten hta hka valve hpe aten galu pat da ai rai yang, valve a hpang kaw shinggyin tawn da ai hka hpe shaw kau ra ai. Steam valve gaw steam hpe jahkring kau ai hpang, hka lim mat ai hka hpe mung shaw kau ra ai. Valve a lawu daw gaw wire plug zawn rai nna, hka pru na matu hpaw mai ai.
3. Non-metal valve ni, nkau mi gaw ngang kang nna n-gun n rawng ai, nkau mi gaw n-gun n rawng ai. Operation galaw ai shaloi, hpaw ai hte pat ai n-gun grai n kaba ai, grau nna n-gun n rawng ai. Object bumps ni hpe koi na matu mung sadi ra ai.
4. Valve nnan hpe lang ai shaloi, packing hpe grai n-gun n-jaw hkra, n-gun n-jaw hkra, valve stem hpe grai n-gun n-jaw hkra, lawan ai hku n-gun yawm mat hkra, hpaw hpaw pat na matu grai n-gun ja hkra n-gun dat ra ai.
Kapaw ai hpe pat shingdang ai valve lata leng hpe gara hku hkrak galaw na
Valve handwheel gaw chyinghka a matu ra kadawn ai arung arai langai mi re. Valve handwheel hpe hkrak hkra galaw ai ladat hpe chye da ai gaw, valve a prat hpe grau galu hkra galaw ya lu ai. Valve handwheel hpe hkrak hkra galaw ai ladat N galaw shi yang, valve hpe pat da ai kun, hpaw da ai kun ngu ai hpe jep yu ra ai. Kaja wa nga yang, valve handwheel hpe ahkying masa hku shinggrup ai gaw, valve hpe hpaw ai maga de rai nna, counterclockwise hku shinggrup ai gaw, valve hpe hpaw ai maga de rai nga ai. Valve hpe shinggrup ai maga de hkan nna hpaw nna pat ai. bungli galaw ai. Valve hpe grau kaja hkra pat da lu na matu, valve a npawt hte valve a dung shara lapran na matut mahkai lam hpe elastic rubber hte galaw ai. Dai majaw, valve hpe hpaw ai shaloi, n-gun hpe ngang grin hkra galaw ra ai, n-gun grai lang ai majaw, valve hpe pat da ai shara (sh) valve a lata n-gang hpe hkra machyi shangun chye ai. Valve handwheel a kaba ai hpe mung, shinggyim masha ni hte maren galaw da ai majaw, valve handwheel a diameter gaw 320mm hta n-pu rai nna, marai langai sha galaw mai ai ngu masat da ai. 320mm hta grau kaba ai (sh) dai hte maren sha re ai valve handwheel gaw masha lahkawng hpe galaw shangun lu ai (sh) F wrench zawn re ai arung arai ni hpe lang nna valve hpe hpaw nna pat na matu ahkang jaw lu ai. . Raitim, lever hte kaga arung arai ni hpe lang nna diaphragm valve hpe hpaw nna pat na matu pat hkum da ai. Gate valve hte globe valve zawn re ai valve ni a matu, jahtum du hkra pat da ai (sh) hpaw dat ai shaloi, 1/4 kaw nna 1/2 du hkra shinggrup nna, thread ni hpe grau n-gun ja hkra galaw ra ai, shing rai yang, valve hpe grai n-gun ja hkra galaw nna, valve hpe n hkra hkra galaw ra ai. Bypass valve ni lawm ai valve ni, ga shadawn:,,, hte kaga valve ni hpe lang ai. Hpaw ai shaloi, bypass valve hpe shawng hpaw nna, shang wa ai hte pru wa ai lapran na pressure shai hkat ai hpe rap ra hkra galaw nna, hpaw ai torque hpe shayawm kau nna, valve hpe asan sha hpaw lu na matu galaw ra ai.
