Dɛn ne akwan titiriw a wɔfa so de gate valve ahorow no si hɔ na wɔhwɛ so?

Sɛ́ nnwinnade titiriw a wɔde hwɛ nsu a ɛsen wɔ mfiridwuma mu nsu afiri nhyehyɛe mu no, sɛnea wɔde si hɔ ne sɛnea wosiesie .Gate valve ahorow .no fa nhyehyɛe no dwumadi a ɛyɛ pintinn ne ahobammɔ ho. Nneɛma atitiriw a edidi so yi yɛ akwan titiriw a wɔfa so yɛ adwuma:

1. Installation phase: Nea edi kan no, yɛ nhwehwɛmu ne pre-treatment de si so dua sɛ .Gate valve .Model, pressure rating, material, ne adwumayɛ tebea no hyia, na akwantu mu ɔsɛe biara nni hɔ. Siesie efĩ a ɛwɔ afiri no mu no, na yɛ mframa a ɛbɔ ne adeyɛ ho sɔhwɛ ahorow ma adwumayɛ tebea horow a ɛho hia. Nea ɛto so abien no, hwɛ akwankyerɛ ne gyinabea, fa si hɔ sɛnea agyan akwankyerɛ kyerɛ no. Ɛsɛ sɛ vertical valve stem no gyina fam, na ɛsɛ sɛ inclination a ɛkɔ soro no yɛ ≤ 15 °. Fa baabi a wode nsa ntwa anaa actuator bedi dwuma (≥ 300mm). Sɛ ɛka bom na ɛsiesie a, ɛsɛ sɛ flange nkitahodi no ne bolt ntokuru no hyia na wɔkyekyere no pɛpɛɛpɛ wɔ akwan horow so; Fa argon arc welding di dwuma sɛ nnyinaso ma welding nkitahodi na fa nkakrankakra ma ɛnnwo. Awiei koraa no, yɛ debugging ne acceptance, bue na to mpɛn 3-5, hwɛ sɛ ɛyɛ stable, na hwɛ sɛ leaks ne samina nsu anaa pressure gauge.

2. Nsiesiei Fa: Ɛsɛ sɛ da biara da nhwehwɛmu hwɛ sɛ gate valve leaks ne valve stem coatings wɔ hɔ, kyerɛw dodow ne bere a wobue ne bere a wɔto mu, na ntɛm ara siesie nneɛma a ɛnteɛ biara. Sɛ yɛhwɛ srade ne nsɔano a, fa srade a ɛyɛ hyew kɛse gu valve no dua no so ɔsram biara, to gate valve no mu ma nsu no nkɔ mu ansa na woagyae bere tenten, na hwɛ seal strip a ɛwɔ soft seal gate valves no mu daa. Ɛsɛ sɛ wɔyɛ nsiesie daa pɛnkoro wɔ asram 6-12 biara mu ma adwumayɛ tebea a ɛfata ne pɛnkoro asram 3 biara ma adwumayɛ tebea a ɛyɛ mmerɛw anaasɛ ɛyɛ hyew kɛse. Sɛ sealing surface no hyɛ a, valve stem no bent, anaasɛ packing leakage no boro standard no so, ɛsɛ sɛ wɔsesa. Sɛ yɛhwɛ ɔhaw ahorow a, sɛ emu nsu bi retu a, wobetumi de bolts no ayɛ den anaasɛ wobetumi de sealant ahyɛ mu. Sɛ ɛyɛ den a, wobetumi de valve seat no asi ananmu; Fa valve no dua no gu ade a ɛma wo ho yɛ hare mu anaasɛ paapae mu na sɛ ɛkyere so a, hohoro mu. Wɔ adwumayɛ tebea soronko mu no, fa ntrɛwmu nkwaa hyehyɛ mu wɔ tebea horow a ɔhyew a ɛkɔ soro wom mu na fa nneɛma a ɛko tia ɔhyew kɛse di dwuma; Wɔyɛ ɔhyew a ɛba fam ayaresa wɔ tebea horow a ɔhyew a ɛba fam wom mu, na wɔpaw valve dua a wɔatrɛw mu; Media a ɛporɔw a wɔde nneɛma a ɛko tia corrosion ayɛ, a wɔsɔ hwɛ daa sɛ ebia pH bo yɛ den anaa.

Akwankyerɛ a ɛfa afiri a wɔde kwati ho: Di nsuo a ɛsen fa nsuo kwan so agyiraeɛhyɛdeɛ a ɛwɔ .Gate valve .; ; Valve dua no mu ntini a ɛyɛ den ≤ Ra0.8 μ m; Fa valve nipadua no kyekyere anaasɛ bɔ nitrogen ho ban ansa na welding. Standardized installation ne nyansahu mu nsiesie betumi atrɛw ɔsom nkwa a gate valves so akɔ soro bɛboro 50% na ɛtew huammɔdi dodow so. Wɔkamfo kyerɛ sɛ wɔnyɛ mmara na wɔtete wɔn a wɔyɛ adwuma no sɛnea nhoma no kyerɛ no.
