Nneɛma Titiriw a Ɛfa Pipeline Valve a Wɔde Sisi Ho Nsɛm Ho

I. Ahosiesie a wɔyɛ ansa na wɔde ahyɛ mu

1. Hwɛ valve specification model, pressure level, ne flow direction identification no mu hwɛ sɛ ɛne design ahwehwɛde ahorow no hyia.

2. Hwɛ sɛnea valve nipadua no mu tew no ho tew na yi nneɛma a ɛbɔ nneɛma a wɔde kyekyere nneɛma ho ban ne nneɛma a ɛyɛ ahɔho fi hɔ.

3. Butt welding nkitahodi valves hia sɛ wɔde grooves prefabricated, na flange nkitahodi valves hia sɛ wɔhwɛ mudi mu kura sealing soro.

II. Installation Akwankyerɛ a Wɔde Di Dwuma

1. Globe valve no nevertical lift check valve a wɔde hwɛ nneɛma soɛsɛ sɛ wɔde si hɔ katee wɔ ɔkwan a agyan a ɛwɔ valve no nipadua so no kyerɛ no so.

2. Wɔ nnyinasosɛm mu no, .non a ɛkɔ soro dua valve, nsuo type ntontom valve, na wobetumi de ball valves ahyɛ afã abien no nyinaa, nanso ɛsɛ sɛ wɔhwɛ yiye sɛnea ɛbɛyɛ a ɛbɛyɛ mmerɛw sɛ wɔde bedi dwuma.

3. Electric / pneumatic valves hia sɛ wɔkora baabi ma actuator adwumayɛ ne nsiesie.

III. Welding Installation Nsɛm a Wɔahyehyɛ

1. Ɛsɛ sɛ wɔma butt welding valve no bue fã bere a wɔreyɛ welding no na amma wɔasiw jamming a ɔhyew deformation de ba no ano.

2. Fa argon arc welding yɛ nnyinaso no, na hwɛ interlayer hyew no so sɛnea ɛbɛyɛ a ɛntra valve no hyew a wɔahyɛ no agyirae.

3. Sɛ wɔde welding wie a, ɛsɛ sɛ wɔsɔ valve no hwɛ sɛnea ɛyɛ adwuma de si so dua sɛ ebue na ɛto mu sɛnea ɛsɛ.

IV. Nneɛma Titiriw a Ɛfa Flange Nkitahodi Ho

1. Flange sealing surfaces no kɔ so yɛ parallel, na deviation a ɛsen biara a wɔma ho kwan no ntra 0.15% wɔ flange no akyi diameter.

2. Ɛsɛ sɛ wɔde gasket no si mfinimfini, ɛsɛ sɛ wɔkyekye bolts no den pɛpɛɛpɛ na ɛyɛ pɛ, na ɛsɛ sɛ wodu rated torque no ho mprɛnsa.

3. Ɛsɛ sɛ wɔkyekyere nhama a ɛka bom a ɛwɔ valve a ɛyɛ hyew kɛse no mu mprenu wɔ tebea a ɛyɛ hyew mu.

V. Nneɛma a Ɛyɛ Paara a Wɔhwɛ So

1. Ahoɔden sɔhwɛ ne nsɔano sɔhwɛ ho hia wɔ bere a wɔde ahyɛ mu akyi.

2. Sɛ wɔrehohoro nhyehyɛe no mu a, ɛsɛ sɛ wotwa regulating valve, flow meter ne nnwinnade afoforo no ho.

3. Hyɛ instɔlehyɛn kyerɛwtohɔ no ma, a data atitiriw te sɛ valve gyinabea nɔma, sɔhwɛ nhyɛso, adwumayɛ torque, ne nea ɛkeka ho ka ho.

Hyɛ no nsow: Ɛnsɛ sɛ wɔde valve no di dwuma sɛ beae a wɔde gyina nsu afiri no so. Valve akɛse hwehwɛ sɛ wɔde nneɛma a wɔde gyina so a ɛyɛ soronko. Sɛ wode si hɔ wie a, ɛsɛ sɛ valve no wɔ baabi a wɔato mu koraa na wɔbɔ ho ban na wɔakwati sɛ ɛrensɛe wɔ cross-operation mu.
