GDF-4 Motor Pipeline Stop Valve mo te Rere Hau
Whakaahuatanga Hua
GDF-4 pipeline mutu takirere ko te takirere ki te ti'aturiraa teitei, te ora ratonga roa me te puku moroiti-moto. Ko te paerewa whakatinanatanga hoahoa matua ko GB / T 20173-2013 "Oil and Natural Gas Industry Pipeline Transmission System Pipeline Valves", me te paerewa hoahoa flange ko GB / T 9113-2010 "Integral Steel Pipe Flange".
Nga waahanga hua
1. He puhoi puhoi me te kati tere, a ko te wa kati ko ≤2s;
2. Te whanuitanga o te pehanga mahi, ko te kaha o te kaha o te mahi ka tae ki te 0.8MPa;
3. Te mate pehanga iti;
4. He pai te hiri, he mahi pumau me te pono;
5. Ko te hoahoa hanganga motuhake o te whakatuwheratanga o te valve me te awhina i te pehanga ka taea te mohio ki te whakatuwheratanga o te valve me te iti o te kawenga me te iti o te kaha o te kaha i roto i te taiao teitei, e whakanui ana i te pono o te mahi valve;
6. Ko te tinana takirere he mea hanga ki te whakarewa konumohe whakarewa, he maamaa te taumaha me te pai ki te aukati waikura, ka taea te tu atu i te pehanga ingoa o 1.6MPa; ko te hanganga katoa he atete ki te paanga, 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;
7. Ko te motuka me te pouaka miihini kua hangaia hei hanganga kua oti te hiri, ko te taumata whakamarumaru ko ≥ IP65, a, ko te motuka me te pouaka miihini kaore he hononga ki te reo whakawhiti, a he pai te mahi pahū-pahū. Kua tino pai ake te pono o te takirere me te oranga ratonga;
8. He kaha te tikanga whakahaere, a ka taea te aukati tika i muri i te whakatuwheratanga me te kati i te waahi, ka taea hoki te kawe ki te whakawhiti waahi;
9. I muri i te whakatuwheratanga me te kati i te waahi, ka maukati aunoa te mahinga o te nekehanga kia kore ai e pakaru te hiko na te kaha o waho i te wa e noho pai ana;
10. He pai te tukatuka o te miihini miihini, he whakakikorua ki te koura te commutator, he mea hanga nga paraihe ki nga konganuku 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. motuka motuka;
11. Ka taea te whakatika i te ahunga whakauru hau.
