Valve handwheels ni gaw, bungli galaw ai arung arai ni hta lang ai bungli galaw ai arung arai ni rai nna, valve ni hpe lata hte gram lajang na matu hte bungli galaw na matu, pipeline system amyu myu hta law law lang lang lang ai. Raitim, aten galu-lang ai shaloi, valve handwheel ni hta, valve a bungli galaw ai lam hte bungli galaw ai lam hpe hkra machyi shangun ai, n bung ai manghkang nkau mi nga chye ai.
Ndai laika buk hta, ndai ahkyak ai daw hpe grau chye na na matu hte gram lajang na matu, valve handwheels ni a matu byin chye ai manghkang ni hte hparan ladat ni hpe tsun dan na re.
1. Valve Lata hte seng nna byin chye ai manghkang ni
- Lata leng ni hpe shinggrup na matu yak ai .
Mai byin ai lam ni: Ndai lam gaw, valve kata kaw pat da ai, valve stem n-gun yawm mat ai, sau n kaja ai, shing nrai, seal ring asak kaba mat ai majaw byin chye ai. Valve hpe aten na na n gram lajang ai rai yang, valve stem hte valve seat lapran na shingjawng ai lam grau law wa nna, n kaja ai hku bungli galaw lu na re.
- Lata leng n-gun yawm mat ai (sh) hkrat sum mat ai
Byin mai ai lam ni: Lata n-gang hte valve stem lapran na matut mahkai lam gaw n-gun yawm mat ai (sh) n-gun yawm mat ai, shing nrai, n-gun jat ai shaloi atsawm n-gun n-jaw ai. Lang ai aten law wa ai hte maren, matut mahkai ai daw hpe n-gun yawm mat ai majaw, n-gun yawm mat ai (sh) hkrat sum mat na pyi rai na re.
- Lata leng hten mat ai (sh) hten za mat ai
Byin mai ai lam ni: Lata lang ai arung arai gaw n-gun n rawng ai majaw (sh) shinggan kaw na hkra ai majaw, shi a hkrang gaw daw mat chye ai. Grai law hkra galaw ai (sh) n kaja ai hku lang ai gaw, lata hte galaw ai n-gang hpe mung lawan ladan hkra machyi shangun chye ai.
- Valve lata lang ai n-gang gaw valve hpe hkrak hkrak n mai gram lajang ai .
Mai byin ai lam ni: Ndai lam gaw, valve seal ring hkrat sum ai majaw, valve dung shara ntsa hta nhprang arai ni hpawng nga ai majaw, shing nrai, valve kata na daw ni hkrat sum mat ai majaw byin chye ai.
2. Valve Handwheels ni a matu byin chye ai manghkang ni hpe hparan ladat ni
- Lata leng hpe shinggrup ai hta yak hkak ai lam ni hpe hparan ladat ni
Valve kata hpe jasan jaseng ai: Shawng nnan, valve kata kaw n-gun n rawng ai (sh) n san seng ai lam nga ai kun ngu ai hpe jep yu u. N san seng ai lam nga yang, laksan jasan jaseng ai tsi lang nna, valve kata hpe jasan jaseng nna, valve stem hte valve seat hpe sau bang hkra galaw mai ai.
Valve stem hpe sau bang ai: Valve stem hpe ayan sau bang nna, n-gun shayawm nna, hkrak hkrak bungli galaw lu na matu, gingdan ai sau (sh) sau hpe lang ra ai.
- Lata leng ni htum mat ai (sh) hkrat sum mat ai hpe hparan ladat ni
Matut mahkai ai shara hpe jep yu u: Lata shingnip hte valve stem lapran na matut mahkai ai shara ni hpe ayan jep yu nna, matut mahkai ai lam ngang kang hkra galaw u. Looseness hpe mu yang, htap htuk ai arung arai ni hpe lang nna n-gun ja hkra galaw u.
Hten za mat sai daw ni hpe galai u: Lata leng matut mahkai ai arung arai ni grai hten mat yang, lata leng hpe ngang ngang jum da lu na matu, matut mahkai ai arung arai nnan ni hpe galai ra ai.
- Hten za mat ai (sh) hten za mat ai lata leng ni hpe hparan ladat ni
N-gun ja ai-arung arai ni hpe lata la u: Aten galu lang ai valve handwheel ni a matu, n-gun ja ai alloy arung arai ni hpe lata na matu hpaji jaw da ai, dai gaw handwheel a ngang grin ai lam hte hkra machyi ai lam hpe hkam sharang lu na matu re.
Grai law hkra galaw ai hpe koi ga: Lata n-gang hpe grai n hkra hkra, lang ai shaloi, atik anang shinggrup ai (sh) grai n-gun dat ai hpe koi nga u.
- Valve handwheel gaw valve hpe hkrak hkrak n mai gram lajang ai manghkang hpe hparan na
Sealing ring hpe jep yu u: Valve sealing ring gaw hkrat sum mat sai kun, asak kaba sai kun ngu ai hpe jep yu u. Manghkang nga ai hpe mu yang aten dep galai kau u.
Valve dung shara hpe jasan jaseng u: Valve dung shara hte valve core ntsa hta awu asin (sh) n san seng ai arung arai ni hpawng de wa nna, sealing effect hpe hkra machyi shangun chye ai. Valve seat hpe n-gun n rawng hkra san seng hkra galaw ra ai.
Gadun dawk
Valve handwheel a shingra tara hku bungli galaw ai lam gaw, valve hpe jai lang ai akyu hte, hpaga lam hta galaw shapraw ai lam a akyu ara hte hkrak matut mahkai nga ai. Dai hpe ayan jep yu ai, gram lajang ai hte hkrak hkra galaw ai hku nna, valve handwheel a byin chye ai manghkang ni hpe atsawm sha koi lu na re.
Teng sha jai lang ai shaloi, lang ai ni gaw bungli galaw ai shara hte valve handwheel hpe lang ai aten hte maren, htap htuk ai arung arai ni hte hkrang ni hpe lata la nna, dai hpe hpaji masa hku nna gram lajang ai lam galaw ra ai, dai hku nna, dai arung arai ni hpe shim lum hkra galaw ra ai.
