Paipa Hau Tere-Kati Hiko Orbital Ball Valve DN50
Tauwāhi Tāuta
Ka taea te whakauru i te paera poroporo ki runga i te paipa hau
Hua Painga:
hautakirere poroporo paipaKo nga ahuatanga me nga painga
1. He puhoi puhoi me te kati tere, a ko te wa kati he iti iho i te rite ranei ki te 2s;
2. Kaore he mate pehanga i te wa e whakamahia ana;
3. He pai te hiri, he mahi pumau me te pono.
4. He hoahoa hanganga ara o roto me waho motuhake, te tuunga tika me te hiri pono; whakaiti i te taipana timata takirere, a ka taea e mohio whakatuwhera takirere i roto i te taiao pehanga tiketike, kawenga iti me te iti te kohi mana;
5. Ko te tinana takirere he mea hanga ki te whakarewa konumohe whakarewa, he maamaa te taumaha, he pai ki te aukati i te waikura, ka taea te tu atu i te pehanga ingoa o 1.6MPa; he ātete te hanganga whānui ki te ohorere, te wiri, te teitei me te iti o te pāmahana, te rehu tote, me etahi atu, ka taea te urutau ki nga momo taiao o waho.
6. Ko te motuka me te pouaka taputapu kua hangaia kia tino hirihia, me te taumata tiaki o ≥ IP65, me te motuka me te pouaka taputapu kaore he hononga ki te reo whakawhiti, me te pai o te mahi pahū. Kua tino pai ake te pono o te takirere me te oranga ratonga;
7. He kaha te kaha o te kaitahuri, a ka taea te aukati tika i muri i te whakatuwheratanga me te kati i te waahi, ka taea ranei te kawe mai ki te whakawhiti waahi;
8. I muri i te whakatuwheratanga me te kati o te paera, ka maukati aunoa te miihini o te nekehanga kia kore ai e pakaru te hiko na te kaha o waho i te wa e noho pai ana;
9. He pai te tukatuka o te miihini miihini, he mea whakakikoruatia te commutator, he mea hanga te paraihe ki te whakarewa utu nui, e tino pai ake ai te aukati me te pumau o te miihini miihini ano, me te whakarite i te mahi pono mo te wa roa. te motuka motuka;
10. Ka taea te whakatika i te ahunga o te hau.
Tohutohu Mo te Whakamahi
1. Me whakanoho te paera ki te taha whakapae, a me whakauru te paera ki runga i te pipeline ma te hononga piriti flange paerewa. I mua i te whakaurunga, me horoi te para rino, te waikura, te puehu me etahi atu mea i te atanga whakaurunga kia kore ai e rakurakuhia te peera me te pakaru ka pakaru mai;
2. Ko te waahanga whakawhiti o te valve ka taea te huri i te 180 ° kia rite ki nga whakaritenga a te kiritaki, a ka taea te whakamahi i muri i te whakarereketanga.
3. Ko nga waea whero me te pango ko nga waea motuka, ka hono te waea whero ki te hiko kino, ka hono te waea pango ki te hiko pai hei whakatuwhera i te waahi;
4. Ka taea te whakauru i te valve ki te tuwhera me te kati i roto i te waahi tohu whakaputa, a ka tūtohu kia whakamahia te tohu whakawhiti; ko te raina ma ko te tuwhera i roto i te waahi tohu tohu urupare, he poto te waahi i te wa e tuwhera ana te waahi, a ka tuwhera te toenga o te whiu; ko te raina kikorangi ko te raina tohu urupare katia-i roto i te tuunga, he poto te waahi ka kati i te waahi. , Ko te toenga o te haerenga he ara iahiko tuwhera;
5. Me noho te paera i roto i te ahua kati i mua i te whakaurunga, ka tino whakakorehia te whakamahi i raro i te ahua o te kaha o te kaha o te hau, o te pupuhi ranei o te hau, a ka tino kore e kitea te pakaru me te ahi tuwhera;
6. Ko te ahua o tenei hua he papa ingoa.
