Wɔ neutral medium ho no, ɛsɛ sɛ wɔpaw rose solenoid valve a wɔde kɔbere a wɔde afra mu sɛ valve shell raw material no nso. Sɛ ɛnte saa a, rust particles bɛhwe ase afi valve shell no mu, titiriw wɔ mmeae a adeyɛ no ntaa mma. Wontumi mfa kɔbere nyɛ ammonia valve no.
2. Nneɛma a ɛwɔ hɔ a ɛyɛ hyew na ɛpae: Ɛsɛ sɛ wɔpaw nneɛma a ɛwɔ relative explosion-adanse grade. Nsuo ntumi nkɔ mu, nsuo a ɛwɔ mu-Adanseɛ ne mfuturo-Adanseɛ nneɛma a wɔde yɛ adwuma no, ɛsɛ sɛ wɔde yɛ abɔnten so anaa mmeaeɛ a wusiw ne mfuturo wɔ.
3. Ɛsɛ sɛ solenoid valve no mu nhyɛso a wɔfrɛ no no boro adwumayɛ nhyɛso a ɛsen biara wɔ paipu no mu.
Nneɛma a wɔde di dwuma:
1. Nsɛm ho amanneɛbɔ su .
1) Wɔpaw solenoid valve ahorow ahorow ma gas, nsu anaa afrafra tebea;
2) Wɔ nneɛma a ɛwɔ media temperature soronko ho no, anyɛ saa a Ross electromagnetic coil no bɛhyew na wɔde sealing material no abɔ akwakoraa, a ɛbɛsɛe ɔsom nkwa no kɛse;
3) Medium viscosity no taa yɛ 50cst. Sɛ ɛboro saa boɔ yi so a, sɛ paipu no ntwemu yɛ kɛseɛ sene 15mm a, wɔde-dwumadi Ross solenoid valve no nyinaa di dwuma; Sɛ paipu no ntwemu nnu 15mm a, wɔde ross solenoid valve a ɛyɛ viscosity a ɛkorɔn no di dwuma.
4) Sɛ media ahotew no nkɔ soro a, ɛsɛ sɛ wɔde backwash filter valve no hyɛ solenoid valve no anim. Sɛ nhyɛso no sua a, wobetumi apaw direct acting diaphragm solenoid valve no;
5) Sɛ media no kyerɛ kwan na ɛmma kwan a ɛkɔ akyi a, ɛsɛ sɛ ɛde abien-kwan a ɛkɔ so di dwuma;
6) Ɛsɛ sɛ wɔpaw ɔhyew a ɛwɔ mfinimfini wɔ solenoid valve a wɔma ho kwan no mu.
2. Pipeline parameters .
1) Sɛnea media akwankyerɛ ne pipeline connection mode no ahwehwɛde ahorow te no, wɔpaw gate valve port ne model no;
2) wɔpaw nominal pipe diameter no sɛnea flow rate ne KV value a ɛwɔ gate valve no mu te, na wobetumi apaw mu ntwemu a ɛwɔ paipu koro no ara mu nso;
3) Adwumayɛ nhyɛsoɔ nsonsonoeɛ: Sɛ adwumayɛ nhyɛsoɔ nsonsonoeɛ a ɛsua koraa no boro 0.04MPa a, wɔbɛtumi apaw indirect pilot type; Sɛ adwumayɛ nhyɛso nsonsonoe a ɛba fam koraa no bɛn anaasɛ ɛba fam sen zero a, ɛsɛ sɛ wɔpaw direct acting type anaa step-a ɛnam-anamɔn so direct type no so.
3. Nneɛma a atwa yɛn ho ahyia tebea .
1) ɛsɛ sɛ nneɛma a atwa yɛn ho ahyia no hyew a ɛsen biara ne nea ɛba fam koraa no wɔ baabi a wɔma ho kwan no;
2) Wɔ tebea a mframa a ɛyɛ nwini no mu yɛ den na nsu a ɛtɔ gu osutɔ mu no, nsu no-adanse ne nsu-adanse Ross solenoid valve no yɛ nea wɔapaw;
3) Wɔ nneɛma a atwa yɛn ho ahyia no mu no, mpɛn pii no, wosow, wosow ne nkɛntɛnso wɔ hɔ, enti ɛsɛ sɛ yɛpaw ahorow soronko, te sɛ po so ross solenoid valve;
4) wɔ tebea a ɛyɛ corrosive anaasɛ ɛyɛ hyew na ɛpae mu no, ɛsɛ sɛ wɔpɛ corrosion-resistant type no sɛnea ahobammɔ ho ahwehwɛde ahorow te;
5) Sɛ beaeɛ a atwa yɛn ho ahyia no sua a, ɛsɛ sɛ wɔpaw-dwumadi Ross solenoid valve no nyinaa, ɛfiri sɛ wɔyi bypass ne manual valve mmiɛnsa no firi mu, na ɛyɛ mmerɛ ma on{2}}line maintenance.
4. Electrogenic tebea .
1) Wɔpaw AC ne DC ROSS solenoid valve ahorow no sɛnea tumi no su te. Sɛ yɛbɛka no ɔkwan biara so a, AC ahoɔden a wɔde ma no yɛ nea ɛfata sɛ wɔde di dwuma;
2) ɛsɛ sɛ wɔpɛ AC 220 V. DC24 V sɛnea ɛbɛyɛ yiye biara;
3) Mpɛn pii no, ahoɔden a ɛsakra no voltage no yɛ +% 10%. - 15% ma AC ne ± 10% ma DC. Sɛ deviation wɔ hɔ a, ɛsɛ sɛ wɔyɛ voltage stabilization measures;
4) Ɛsɛ sɛ wɔpaw rated voltage ne tumi a wɔde di dwuma no sɛnea tumi a ɛwɔ hɔ mfiase no te. Ɛho hia sɛ wɔde wɔn adwene si VA bo a ɛkorɔn no so bere a wɔrefi AC ase no, na ɛsɛ sɛ wɔpɛ akwankyerɛ a ɛnyɛ tẽẽ a ɛkyerɛ ROSS solenoid valve no bere a tumi no nnɔɔso no.
5. Control a ɛyɛ pɛpɛɛpɛ .
1) Mpɛn pii no, solenoid valve no wɔ afã abien pɛ: ON ne OFF, enti ɛsɛ sɛ wɔpaw multi position solenoid valve bere a control no pɛpɛɛpɛyɛ no yɛ kɛse na parameters no gyina;
2) Action time: Ɛkyerɛ anyinam ahoɔden sɛnkyerɛnne a ɛwɔ so anaasɛ ɛdum kɔ valve titiriw no so .
