I. Nnyinasosɛm a Wɔde Paw NneɛmaNwansena Valves

1. Structure type a wɔpaw

Mfinimfini ntontom valve (mfinimfini line type) .:Valve dua ne butterfly disc no yɛ nea ɛwɔ mfinimfini, na ne nhyehyɛe yɛ mmerɛw na ɛho ka sua. Nsɔano no gyina rɔba a ɛyɛ mmerɛw so. Ɛfata ma mmere a ɔhyew ne nhyɛso a ɛfata na ahwehwɛde a emu yɛ den biara nni mu.

Nwansena valve biako a ɛyɛ nwonwa:Wɔde valve dua no fi ntontom diski no mfinimfini, na ɛtew akasakasa a ɛda nneɛma a wɔde kata so ntam bere a ɛreyɛ adwuma no so na ɛtrɛw ne nkwa nna mu. Ɛyɛ papa ma nhyɛso a ɛwɔ mfinimfini ne nea ɛba fam a ɛhwehwɛ sɛ wɔtaa bue na wɔto mu.

Double eccentric butterfly valve (nwansena valve a ɛyɛ adwuma yiye):Wɔde valve dua no fi butterfly disc ne sealing surface center no nyinaa so, na ɛma wotumi yɛ adwuma a frictionless. Mpɛn pii no, wɔde dade anaasɛ nneɛma a wɔde afrafra nsɔano na ɛyɛ adwuma. Ɛyɛ papa ma ɔhyew a ɛkɔ soro, nhyɛso kɛse, nea ɛporɔw, anaa nneɛma nketenkete.

Nwansena valve a ɛyɛ nwonwa abiɛsa:Sɛ ɛka dual eccentricity ne beveled conical sealing pair bom a, ɛma ɛyɛ zero friction ne zero leakage, a ɛwɔ ɔhyew a ɛkorɔn ne nhyɛso a ɛkorɔn a ɛko tia. Ɛyɛ papa ma adwumayɛ tebea a emu yɛ den (sɛ nhwɛso no, nsuonwini, ngo/mframa, nsɛm ho amanneɛbɔ a ɛyɛ hyew kɛse).

2. Drive mode a wɔpaw

Akwankyerɛ:ma diameters nketewa (DN≤200), nhyɛso a ɛba fam, anaasɛ adwumayɛ tebea horow a wɔntaa nyɛ.

Worm gear a wɔde di dwuma:Ɛfata ma medium to large diameter applications a ɛhwehwɛ sɛ wɔyɛ adwuma a wɔmmɔ mmɔden biara anaasɛ wɔyɛ flow regulation.

Mframa/Ɛlektrik ahoɔden:Remote control, automation systems, anaasɛ ahwehwɛde ahorow a ɛfa ogya a wɔde to mu ntɛmntɛm (sɛ nhwɛso no, ogya alarm nhyehyɛe, ntɛmpɛ a wɔde to mu).

3. Nneɛma ne nneɛma a wɔde hyɛ mu

Nsɔano a ɛyɛ mmerɛw (rɔba, PTFE, ne nea ɛkeka ho): nsɔano pa, nanso ɔhyew ne nhyɛso a ɛko tia anohyeto (mpɛn pii no ≤120°C, PN≤1.6MPa). Ɛfata ma nsu, mframa ne mmerɛw corrosion media.

Dade nsɔano (dade a ɛnyɛ den, carbide a wɔde semɛnte ayɛ): Ɔhyew a ɛkɔ soro (ɛkɔ 600°C), nhyɛso kɛse, ne nsɔano ne nsɛe, nanso nsɔano adwumayɛ no sua kakra sen nsɔano a ɛyɛ mmerɛw. Ɛfata ma nsɛm ho amanneɛbɔ a ɛyɛ hyew kɛse wɔ dade, anyinam ahoɔden mfiri, ne petrochemicals mu.

Nipadua mu nneɛma: Dade a wɔagu, carbon dade, dade a ɛnyɛ den, dade a wɔde afrafra, anaa plastic/rɔba a wɔde akata so a egyina sɛnea ade no betumi asɛe so.

4. Nhyɛso ne ɔhyew a ɛwɔ hɔ:

Wɔtaa de ntontom valves a wɔatoto mu brɛoo di dwuma ma PN10 ~ PN16, a ɔhyew yɛ ≤120°C. Nwansena a wɔde dade a wɔatoto mu abiɛsa a ɛyɛ nwonwa betumi adu PN100 so, na ne hyew yɛ ≥600°C.

5. Kar Ho Su Ahorow

Sɛ ɛho hia sɛ wɔyɛ nsuo a ɛsen ho nhyehyɛeɛ a, paw ntontom valve a ɛwɔ linear anaa ɔha mu nkyekyɛmu a ɛyɛ pɛ nsuo su (sɛ nhwɛsoɔ, V-shaped disc).

6. Installation space ne flow akwankyerɛ:Butterfly valve no wɔ nhyehyɛe a ɛyɛ ketewaa bi, na ɛma ɛfata ma nsu afiri a baabi sua. Mpɛn pii no, anohyeto biara nni hɔ a ɛkyerɛ sɛnea ɛsen no, nanso wɔ ntontom valve ahorow a ɛyɛ soronko abiɛsa ho no, ɛsɛ sɛ wɔkyerɛ ɔkwan a wɔfa so sen no.

II. Mmere a Ɛfa Ho

. Sɛ wopɛ pɔmpɛ outlets ne flow regulation: paw worm gear anaa anyinam ahoɔden control butterfly valves.

2. Petrochemical ne natural gas pipelines: Wɔpaw butterfly valves abiɛsa a wɔde dade atoto mu a ɛyɛ nwonwa sɛnea ɛbɛyɛ a ɛbɛko atia nhyɛso kɛse na wɔasiw nsu a ɛtwetwe ano. Nneɛma a ɛporɔw (sɛ nhwɛso no, acid/alkali): Wɔde ntontom valve a wɔde fluorine ayɛ anaasɛ alloy valve a ɛko tia nsɛe na edi dwuma.

3. Wɔ anyinam ahoɔden adwumayɛbea, nsu a ɛkyinkyini nhyehyɛe, ne mframa a wɔde fi mu a wɔde yi sulfurization: medium anaa abien eccentric rɔba-lined ntontom valves. Wɔ nsuo afiri a wɔde fa nsuo mu (sɛ nhwɛsoɔ no, mfiri a ɛboa nhyehyɛeɛ a ɛwɔ anyinam ahoɔden mfiri mu): ntontom valve mmiɛnsa a wɔde dadeɛ a wɔatoto mu a ɛyɛ nwonwa.

4. HVAC (Heating, Ventilation, and Air Conditioning) nsuo a ɛyɛ nwini ne nsuo a ɛyɛ hyeɛ a wɔde di akɔneaba: ntontom valve a wɔatoto mu brɛoo a wɔde hwɛ nsuo a ɛsen anaa wɔtwa.

5. Wɔ po so mfiridwuma ne po mu nsu nhama ho: duplex stainless dade ntontom valves a ɛko tia nsɛe anaasɛ rɔba-lined butterfly valves.

6. Aduan ne aduruyɛ mu ntontom valves (dade a ɛnyɛ den a wɔayɛ no fɛfɛɛfɛ, nneɛma a wɔde hyɛ mu ntɛmntɛm) di ahwehwɛde ahorow a ɛnyɛ sterile ho dwuma.

7. Mfutuma ne nneɛma nketenkete a ɛwɔ adwumayɛ tebea titiriw mu: Wɔkamfo kyerɛ sɛ wɔmfa ntontom valve a wɔatoto mu denneennen a ɛmma ɛnsɛe (sɛ nhwɛso no, wɔ mine powder a wɔde fa mu).

Vacuum nhyehyɛe: Vacuum soronkonwansena valvehwɛ hu sɛ nsɔano adwumayɛ.
