In the automatic water filling device of cooling pond, described electromagnetic valve upper inlet end is provided with bolt, and described water source interface place is provided with screw thread, and described bolt and screw thread bore can match.Bolt thread cooperates fastening effective.
In the automatic water filling device of cooling pond, described bolt and hickey go out to be provided with rubber layer.Rubber layer is set, improves sealing joint property.
In the automatic water filling device of cooling pond, described hydraulic pressure sensor is arranged on the same side position of water source interface.Same side position is convenient to cabling.
In the automatic water filling device of cooling pond, the pressure meter that is used to detect the pond depth of water is set outside the described cooling pond.Observe the water retention capacity in the pond, can judge the whether operate as normal of this device.
In the automatic water filling device of cooling pond, described signal processor is A/D converter.Controller output analog signal, therefore the electromagnetic valve receiving digital signals need change into data signal with analog signal.
Compared with prior art, the automatic water filling device of this cooling pond has the following advantages:
1, detect through hydraulic pressure sensor, controller control realizes automatic water filling, saves time conveniently, for the workman has reduced workload.
2, in the pond outer setting pressure meter, be convenient to the workman and observe the water retention capacity in the cooling pond, avoid causing the not enough situation of retaining because of device damage.
