I-GDF-4 Motor Pipeline Stop Valve Yemitha Yokugeleza Kwegesi

Inombolo yemodeli: GDF-4

Incazelo emfushane:

I-valve yokuvala ipayipi ye-GDF-4 iyivalvu esetshenziswa kumapayipi egesi ukulawula ukucisha kwendawo yokudlulisa. Ingafakwa epayipini legesi njengengxenye ezimele, futhi ingakwazi ukulawula ngokuzenzakalelayo ukuphuma kwegesi ngokuthembekile; ingasetshenziswa futhi ngokuhambisana nemitha yokugeleza ukuze ibone ukuhlanganiswa kokusebenza kwemitha yegesi yamapayipi kanye nokulawula ukucisha.

Incazelo Yomkhiqizo

I-valve yokumisa ipayipi ye-GDF-4 iyivalvu enokwethenjelwa okuphezulu, impilo ende yesevisi kanye ne-micro-motor drive. Izinga eliyinhloko lokuqaliswa kokuklama yi-GB/T 20173-2013 "Amapayipi Okuhambisa Amapayipi Embonini Kawoyela Negesi Yemvelo", futhi izinga lomklamo we-flange yi-GB/T 9113-2010 "I-Integral Steel Pipe Flange".

Izici Zomkhiqizo

1. I-valve evula kancane futhi evala ngokushesha, futhi isikhathi sokuvala singu-≤2s;

2. Uhlu olubanzi lwengcindezi yokusebenza, ingcindezi yokusebenza ephezulu ingafinyelela ku-0.8MPa;

3. Ukulahlekelwa kwengcindezi encane;

4. Ukubekwa uphawu okuhle, ukusebenza okuzinzile nokuthembekile;

5. Idizayini yesakhiwo esikhethekile sokuvula i-valve nokukhululeka kwengcindezi ingakwazi ukubona ukuvulwa kwe-valve ngomthwalo ophansi kanye nokusetshenziswa kwamandla aphansi endaweni yokucindezela okukhulu, okuthuthukisa ukuthembeka kokusebenza kwe-valve;

6. Umzimba we-valve wenziwe nge-cast aluminium alloy, enesisindo esincane futhi enhle ekumelana nokugqwala, futhi ingakwazi ukumelana nokucindezela okuzisholo okungu-1.6MPa; Isakhiwo sonke siyamelana nomthelela, ukudlidliza, izinga lokushisa eliphezulu neliphansi, isifutho sikasawoti, njll., futhi singakwazi ukuzivumelanisa nezimo ezihlukahlukene zangaphandle eziyinkimbinkimbi;

7. Injini kanye nebhokisi likagiya kuklanywe njengesakhiwo esivalwe ngokugcwele, izinga lokuvikela lithi ≥ IP65, futhi injini nebhokisi likagiya azixhumani nendawo yokudlulisela, nokusebenza kokuvikela ukuqhuma kuhle. Ukwethenjwa kwe-valve okuthuthukisiwe kakhulu nempilo yesevisi;

8. I-executive mechanism inamandla, futhi ingavinjelwa ngokuqondile ngemva kokuvula nokuvalwa kwendawo, futhi ingalethwa ekushintsheni isikhundla;

9. Ngemuva kokuthi i-valve ivuliwe futhi ivalwe endaweni, indlela yokunyakaza ikhiywa ngokuzenzakalelayo ukuze kuqinisekiswe ukuthi i-valve ngeke isebenze kabi ngenxa yamandla angaphandle lapho isesimweni esizinzile;

10. I-micro-motor icutshungulwa kahle, i-commutator ifakwe ngegolide, futhi amabhulashi enziwe ngezinsimbi eziyigugu, okuthuthukisa kakhulu ukumelana nokugqwala nokuzinza kwe-micro-motor ngokwayo, iqinisekisa ukusebenza okuthembekile kwesikhathi eside i-valve yemoto;

11. Isiqondiso somoya singashintshwa.
