the equipment for calibration of liquefied gas bot

1, Features This equipment designed for calibration cylinder valve used, its structure is advanced, reasonable, equipment, compact, high efficiency and good working conditions, is the ideal equipment maintenance cylinder valve.2, technical parameters 1. Check valve seat disc Number: 4 2. Check tank size (L × W × H): 550 × 300 × 250 mm 3. Check Air Pressure: 2.1 Mpa 4. Hour check valve a few: 40 5. Weight: 110 kg 6. Overall dimensions (L × W × H): 600 × 450 × 1100 mm3, equipment, structure and use The equipment consists of sink, frame, shaft, switch plates, valves and other parts of the composition. In the air before the first four-pass valve on the valve seat, the hand-tightened, and then open the inlet valve, a gradual step-up to 2.1Mpa, no significant leakage, the rotation transfer plate, will be followed by sinking into the water valve test and try to close the air inlet valve exhausted, and open a valve will be more than air into the trial to do, the pressure back to zero after the next step removable valve operations (if you want to test stem leakage does not leak, it would take the bottle special plug valve for export alone dead, open the valve, again leak, but at this time should stay at a valve designed to release gas, and not to export blocked).
