I-GDF-4 Motor Pipeline Stop Valve ye-Gas Flow Meter
Ingcaciso yeMveliso
Ivalve yokumisa imibhobho ye-GDF-4 yivalve enokuthembeka okuphezulu, ubomi benkonzo ende kunye ne-micro-motor drive. Umgangatho oyintloko wokuphunyezwa koyilo yi-GB / T 20173-2013 "I-Oil kunye ne-Natural Gas Industry Pipeline Transmission System Pipeline Valves", kunye nomgangatho woyilo lwe-flange yi-GB / T 9113-2010 "I-Integral Steel Pipe Flange".
Iimpawu zeMveliso
1. I-valve yokuvula ngokukhawuleza kunye nokuvala ngokukhawuleza, kwaye ixesha lokuvala ngu-≤2s;
2. Uluhlu olubanzi loxinzelelo lokusebenza, uxinzelelo oluphezulu lokusebenza lunokufikelela kwi-0.8MPa;
3. Ukulahlekelwa kwengcinezelo encinci;
4. Ukutywinwa kakuhle, ukusebenza okuzinzileyo nokuthembekileyo;
5. Uyilo olukhethekileyo lwesakhiwo sokuvula ivalve kunye nokunciphisa uxinzelelo kunokuqonda ukuvuleka kwevalve ngomthwalo ophantsi kunye nokusetyenziswa kwamandla aphantsi kwindawo yoxinzelelo oluphezulu, okwandisa ukuthembeka komsebenzi wevalve;
6. Umzimba wevalve wenziwe nge-alloy ye-aluminium ephothiweyo, enobunzima obulula kwaye ilungile kwi-corrosion resistance, kwaye inokumelana noxinzelelo lwe-1.6MPa; Ulwakhiwo lulonke luyamelana nempembelelo, ukungcangcazela, ubushushu obuphezulu kunye obuphantsi, isitshizi setyuwa, njl.
7. I-motor kunye ne-gearbox zenzelwe njengesakhiwo esitywinwe ngokupheleleyo, inqanaba lokukhusela ngu-≥ IP65, kwaye i-motor kunye ne-gearbox ayinakho uqhagamshelwano kunye ne-transmission medium, kwaye ukusebenza kobungqina bokuqhuma kulungile. Kuphuculwe kakhulu ukuthembeka kwevalvu kunye nobomi benkonzo;
8. Isixhobo sokulawula sinamandla, kwaye sinokuvalwa ngokuthe ngqo emva kokuvula kunye nokuvalwa kwendawo, kwaye kunokuziswa kwindawo yokutshintsha;
9. Emva kokuba i-valve ivuliwe kwaye ivalwe endaweni, indlela yokuhamba ivalwe ngokuzenzekelayo ukuqinisekisa ukuba i-valve ayiyi kungasebenzi ngenxa yamandla angaphandle xa ikwimeko ezinzile;
10. I-micro-motor icutshungulwe ngokucokisekileyo, i-commutator ifakwe ngegolide, kwaye iibrashi zenziwe ngeentsimbi ezixabisekileyo, eziphucula kakhulu ukuxhathisa kwe-corrosion kunye nokuzinza kwe-micro-motor ngokwayo, ukuqinisekisa ukusebenza okuthembekileyo kwexesha elide. ivalve yemoto;
11. Ulwalathiso lokungenisa umoya lunokulungiswa.
