Hydraulic Counter weight Flanged Butterfly Valve

DN 2250mm Flanged Butterfly Valve Hydraulic Counterweight For Hydropower Station

Basic parameter:

Hydraulic Control Slow-closing Butterfly Valve can be divided into Heavy Hammer Type and Accumulator Type.

The valve is made up by the valve noumenon, actuator, hydraulic station, and electric control case.

The valve noumenon is made up by valve body, disc, shaft, transmission shaft and sealing package, etc.

The heavy hammer type valve body adopts the horizontal structure; the shaft of the valve adopts the semi- shaft structure.

The accumulator type generally adopts horizontal type.The actuator is made up by the connection and transmission pieces such as hydraulic jar, rocking arm, support wallboard (heavy hammer type has heavy hammer, lever, locking oil cylinder, etc.) It is the main executive body of valve, which open and close the valve hydraulic.

The transmission hydraulic jar has quick-closing time adjusting valve, slow -closing time adjusting valve and angle adjusting valve.

The hydraulic pressure station is made up by oil pump assembly, hand operated pump, accumulator, electromagnetic valve, overflow valve, flow control valve, stop valve, hydraulic pressure integrated lump, oil tank, etc.

In automatic pressure maintaining heavy hammer type control system, the accumulator can be used as compensation of systematic pressure.

In automatic pressure maintaining heavy hammer type with locking system, the accumulator can be used as compensation of systematic pressure and unlock the locking oil cylinder.

In accumulator type control system, the two accumulators can device both as spare, offer initiative strength source for the fact that the valve is opened and closed.

The flow control valve is used to adjust the time of opening the valve.

The hand operated pump is used for the systematic debugging and opening and closing the valve under special operating mode.

The hydraulic systematic electromagnetic reversing valve is generally a obverse action type, which is when the electromagnetic valve connects with electricity, the butterfly valve opens while do not connect with electricity, the butterfly valve closed. Reaction type on the contrary, which is when the electromagnetic valve does not connect with electricity, the butterfly valve opens, while it connects with electricity, the butterfly valve closed. The obverse action type is normal while the reaction type should be noticed when you make orderings.
