GDF-1 Motorized Ball Valve Special for Gas Pipeline

Tauira Nama: GDF-1

Whakaahuatanga Poto:

GDF-1 hau pipeline takirere motuhake ko te takirere whakamahia i runga i pipeline hau ki te whakahaere i runga-atu o te reo tuku. Ka taea te whakauru ki runga i te paipa hau hei waahanga motuhake, ka taea te whakahaere aunoa i te kati o te hau ma te pono; ka taea hoki te whakamahi i te taha o te mita rere ki te mohio ki te whakauru mahi o te ine hau paipa me te mana whakahaere.

Hua Painga

Ko nga ahuatanga me nga painga o te paera poroporo hau
1. He nui te pehanga mahi, a ka taea te whakatuwhera me te kati i te paera i roto i te taiao mahi o 0.4MPa.
2. He poto te wa whakatuwheratanga me te kati kati, a ko te wa whakatuwhera me te kati kati he iti iho i te rite ranei ki te 50s i raro i te ngaohiko mahi rohe o 7.2V.
3. Karekau he mate pehanga, a, ko te hoahoa hangahanga mate kore-pehanga me te diameter takirere e rite ana ki te diameter putorino.
4. He pai te mahi hiri o te paera kati, a ko te hiri he mea hanga ki te rapa nitrile me te aukati teitei o te pāmahana (60 ℃) me te iti o te pāmahana (-25 ℃).
5. Ki te whakakā rohe, ka taea e ia te kite tika i te mana i roto i te tuunga o te paera whakawhiti.
6. He pai te rere o te valve on-off, kaore he wiri me te haruru iti.
7. Ko te motuka me te pouaka taputapu kua oti te hiri, a ko te taumata tiaki ko ≥IP65, e tino aukati ana i te whakaurunga o te reo whakawhiti, me te pai o te mahi pahū.
8. Ko te tinana valve he mea hanga ki te konumohe, ka taea te tu atu i te pehanga 1.6MPa, te aukati i te wiri me te wiri, me te urutau ki nga taiao uaua.
9. He anodized te mata o te tinana valve, he ataahua, he ma, he pai te mahi anti-corrosion.

Tohutohu Mo te Whakamahi

1. Ko te waea whero me te waea pango nga waea hiko, ka hono te waea pango ki te hiko pai, ka hono te waea whero ki te hiko kino hei whakatuwhera i te hiko.
2. Ko nga rarangi whakaputa tohu tohu-a-waa: 2 nga raina ma ko nga raina tohu tohu-tuwhera-tuwhera, he poto te waahi i te wa e tu ana te waahi; Ko nga raina kikorangi e 2 ko nga raina tohu tohu kati-kati i roto i te waahi, he poto te waahi i te wa e tu ana te waahi; (I muri i te whakatuwheratanga, i te kati ranei o te hiko, ka tukuna te mana hiko mo te 5s ki te whakarite i te pumau o te tohu tohu-i roto)
3. Ko te pouaka whakaheke o te valve ka taea te huri i nga nekehanga 180 i runga i te pai o te kaihoko ki te whakauru i te pouaka whakahaere, ka taea te whakamahi i te waahi i muri i te hurihanga.
4. Whakamahia nga tutaki flange paerewa hei hono i nga marere, nga paipa, me nga mita rere. I mua i te whakaurunga, me ata horoi te mata mutunga o te flange kia kore ai te para rino, te waikura, te puehu me etahi atu mea koi kei te mata o te pito kia kore e rakuraku te peera me te pakaru.
5. Me whakauru te valve ki roto i te pipeline, i te flowmeter ranei me te kati o te valve. Ka tino rahuitia te whakamahi i roto i te ahua o te pehanga nui, te rerenga hau ranei, me te kite i te rerenga me te ahi tuwhera.
6. Ko te ahua o tenei hua ka whakaratohia ki te papa ingoa.
