GDF-4 Lub cev muaj zog Pipeline Nres Valve rau Gas Flow Meter

Qauv No.: GDF-4

Lus piav qhia luv luv:

GDF-4 pipeline shut-off valve yog lub valve siv rau cov kav dej xa hluav taws xob los tswj qhov nruab nrab ntawm kev sib kis. Nws tuaj yeem ntsia tau rau ntawm cov kav dej roj raws li cov khoom siv ywj pheej, thiab tuaj yeem tswj tau qhov kev tawm ntawm cov roj tau ntseeg tau; Nws kuj tseem tuaj yeem siv ua ke nrog lub ntsuas dej ntws kom paub txog kev ua haujlwm ntawm kev ntsuas cov kav dej thiab kev tswj xyuas kev tawm.

Khoom nta

1. Nws yog qhov qhib qeeb thiab nrawm nrawm, thiab lub sijhawm kaw yog ≤2s;

2. Ntau yam ntawm kev ua haujlwm siab, qhov siab tshaj plaws ua haujlwm siab tuaj yeem ncav cuag 0.8MPa;

3. Kev poob siab me me;

4. Zoo sealing, ruaj khov thiab txhim khu kev qha kev ua tau zoo;

5. Cov qauv tsim tshwj xeeb ntawm lub valve qhib thiab lub siab nyem tuaj yeem paub txog lub valve qhib nrog qis load thiab qis zog noj nyob rau hauv ib puag ncig siab, uas txhim khu kev ntseeg siab ntawm valve ua haujlwm;

6. Lub cev valve yog ua los ntawm cam khwb cia txhuas alloy, uas yog lub teeb nyob rau hauv hnyav thiab zoo nyob rau hauv corrosion kuj, thiab muaj peev xwm tiv taus lub nominal siab ntawm 1.6MPa; tag nrho cov qauv yog resistant rau kev cuam tshuam, kev co, siab thiab tsis kub, ntsev tsuag, thiab lwm yam, thiab tuaj yeem hloov mus rau ntau qhov chaw sab nraum zoov;

7. Lub cev muaj zog thiab gearbox yog tsim los ua cov qauv kaw tag nrho, qib kev tiv thaiv yog ≥ IP65, thiab lub cev muaj zog thiab lub gearbox tsis muaj kev sib cuag nrog lub nruab nrab kis tau tus mob, thiab kev ua haujlwm tawg tau zoo. Zoo heev txhim kho valve kev ntseeg tau thiab kev pab lub neej;

8. Cov txheej txheem tswj hwm muaj zog, thiab nws tuaj yeem raug thaiv ncaj qha tom qab qhib thiab kaw nyob rau hauv qhov chaw, thiab tseem tuaj yeem coj mus rau txoj haujlwm hloov;

9. Tom qab lub valve qhib thiab kaw nyob rau hauv qhov chaw, lub zog mechanism yog cia li kaw kom ntseeg tau tias lub valve yuav tsis malfunction vim yog sab nraud quab yuam thaum nws nyob rau hauv ib tug ruaj khov lub xeev;

10. Lub micro-lub cev muaj zog ua haujlwm zoo, lub commutator yog kub-plated, thiab cov txhuam hniav yog ua los ntawm cov hlau zoo, uas zoo heev txhim kho corrosion thiab stability ntawm lub micro-motor nws tus kheej, kom ntseeg tau lub sij hawm ntev kev lag luam txhim khu kev qha ntawm lub lub cev muaj zog valve;

11. Cov kev taw qhia huab cua tuaj yeem hloov kho.
