I-GDF-4 Motor Pipeline Stop Valve ye-Gas Flow Meter

Inombolo yoMzekelo: GDF-4

Inkcazelo emfutshane:

Ivalve yokuvalwa kombhobho we-GDF-4 sisivalo esisetyenziswa kwimibhobho yerhasi ukulawula ukucinywa kwendawo yothumelo. Inokufakwa kumbhobho wegesi njengenxalenye ezimeleyo, kwaye inokulawula ngokuzenzekelayo ukukhutshwa kwegesi ngokuthembekileyo; ingasetyenziselwa kunye nemitha yokuhamba ukuze iqonde ukuhlanganiswa okusebenzayo kwemitha yegesi yombhobho kunye nokulawula ukucima.

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.
