Hydraulic pumping check valve technical requirements

Hydraulic pumping check valve purposes:

The liquid-operated extraction check valve is installed in the extraction horizontal pipeline leading from the low-pressure gas-conducting pipe in the steam turbine, mainly to prevent over-speeding of the steam turbine due to steam or accidents in the extraction pipe.

Hydraulic pumping check valve

Hydraulic pumping check valve features:

1, the valve plate with a large bevel angle, shorten the opening and closing stroke, hydraulic aids to achieve fast opening and closing, three-dimensional eccentric seal structure, open the seal that is separated, close the contact is sealed, open and close light and flexible. (≤ DN250 using cut-off type)

2, the valve plate by the thrust, reaching the deadline, the purpose of checking.

3, fast closing time up to 0.5 ~ 1 second, emergency cut off safe and reliable.

Hydraulic pumping check valve technical requirements:

1. Hydraulic source interface: RC1 / 2

2. Hydraulic cylinder operating pressure: 2.0 MPa,

3. Emergency cut off time; 0.5-1 seconds

4. Connecting flange: JB / T79-94 GB / 9113.2000

5. Structure length: GB 12221-89

6. Power supply voltage: AC220-DC24V
