GDF-4 Motor Pipeline Taofi Valve mo Meter Flow
Fa'amatalaga o oloa
GDF-4 pipeline stop valve o se valve e maualuga le faʻatuatuaina, umi o le ola tautua ma le micro-motor drive. O le faʻataʻitaʻiga autu o le faʻatinoga o le GB / T 20173-2013 "Suauu ma le Natural Gas Alamanuia Pipeline Transmission System Pipeline Valves", ma le faʻataʻitaʻiga mamanu flange o GB / T 9113-2010 "Integral Steel Pipe Flange".
Oloa Fa'ailoga
1. O se valve faʻagesegese ma tapuni vave, ma o le taimi tapuni e ≤2s;
2. O le tele o galuega mamafa, o le maualuga o le mamafa o galuega e mafai ona oʻo atu i le 0.8MPa;
3. Laititi omiga gau;
4. Fa'amaufa'ailoga lelei, mautu ma fa'atuatuaina fa'atinoga;
5. O le fausaga faʻapitoa faʻapitoa o le tatalaina o le valve ma le faʻamalosia o le mamafa e mafai ona iloa ai le tatalaina o le valve ma le maualalo o le mamafa ma le maualalo o le eletise i le siosiomaga maualuga, lea e faʻaleleia ai le faʻatuatuaina o le faʻaogaina o le valve;
6. O le tino valve e faia i le alumini alumini, lea e mama i le mamafa ma lelei i le faʻafefeteina, ma e mafai ona tatalia le mamafa o le 1.6MPa; o le fausaga atoa e teteʻe i aʻafiaga, vibration, maualuga ma maualalo le vevela, masima masima, ma isi, ma e mafai ona faʻafetaui i siosiomaga lavelave eseese i fafo;
7. O le afi ma le atigipusa ua mamanuina e avea o se fausaga faʻamaufaʻailoga atoatoa, o le puipuiga o le maualuga o le ≥ IP65, ma le afi ma le pusa e leai se fesoʻotaʻiga ma le faʻasalalauga, ma e lelei le faʻatinoina o le pa. Faʻaleleia atili le faʻamaoni valve ma le ola tautua;
8. E malosi le masini faʻapitoa, ma e mafai ona poloka saʻo pe a maeʻa le tatalaina ma le tapunia, ma e mafai foi ona aumai i le suiga o le tulaga;
9. A maeʻa ona tatalaina le valve ma tapuni i le nofoaga, e otometi lava ona loka le masini e faʻamautinoa ai o le a le faʻaleagaina le valve ona o le malosi mai fafo pe a i ai i se tulaga mautu;
10. O le micro-motor e lelei ona faʻaogaina, o le commutator o loʻo faʻapipiʻiina auro, ma o pulumu o loʻo faia i uʻamea taua, lea e faʻaleleia atili ai le faʻafefeteina ma le mautu o le micro-motor lava ia, faʻamautinoa le faʻatinoina o le faʻatuatuaina mo se taimi umi. afi afi;
11. E mafai ona fetuutuunai le itu ea intake.
