Abstract
The invention relates to a water hammer eliminating device for a hydropower station fire pump. The water hammer eliminating device comprises an outer pipe and an inner pipe embedded in the outer pipe in a sleeved manner. The two ends of the outer pipe are provided with annular sealing plates so that an airtight air cavity can be jointly composed of the outer pipe, the inner pipe and the sealing plates. The outer surface of the inner pipe is sleeved with a cylindrical telescopic inner container. Multiple through holes are formed in the side wall of the inner pipe. One end of the outer pipe is provided with an electromagnetic valve controlling the inner pipe to be opened and closed. The outer pipe is provided with a pressure gauge for monitoring changes of air pressure of the air cavity. The water hammer eliminating device further comprises a PLC control system arranged on the outer side wall of the outer pipe, an alarm and a storage battery. The storage battery supplies electricity to the PLC control system, the alarm and the electromagnetic valve. The PLC control system monitors the value of the pressure gauge and controls running of the electromagnetic valve and the alarm. The water hammer eliminating device is simple in structure and convenient and safe to use.
Description
Technical field
The present invention relates to a kind of power station fire pump water hammer cancellation element.
Background technology
Fire pump start and stop moment exit of pump water pressure fluctuations are big, cause hydraulic pipeline high vibration, swing, ripple
Pipe serious distortion, there is potential safety hazard in equipment.
In water or other medium course of conveying, the stream when moment open and close valve or moment starting, stopping pump operation
, there is water hammer in amount, pressure jump in pipe, especially skyscraper is most commonly seen, and water hammer removes and produces noise and shake
Dynamic outer, affect the action of whole system when serious, threaten the safety of the person and equipment.
Content of the invention
The problem that the present invention is directed to above-mentioned prior art presence makes improvement, and that is, the technical problem to be solved is
A kind of power station fire pump water hammer cancellation element is provided, water hammer can be eliminated, and guarantee safety.
In order to solve above-mentioned technical problem, the technical scheme is that：A kind of power station fire pump water hammer eliminates dress
Put, including outer tube and the inner tube that is nested in outer tube, described outer tube two ends are provided with ring sealing plate so that outer tube, inner tube and
Shrouding collectively forms an airtight air cavity, and said inner tube outer surface is arranged with the flexible inner bag of tubular, and said inner tube side wall is provided with many
Individual through hole, one end of described outer tube is provided with the magnetic valve controlling inner tube to open and close, and described outer tube is provided with monitoring air cavity air pressure
The pressure gauge of change, also includes a PLC control system being arranged on outer tube lateral wall, alarm and battery, described electric power storage
Pond is PLC control system, alarm and solenoid valve, PLC control system monitor manometric numerical value and control magnetic valve and
The operating of alarm.
Further, the two ends of described outer tube are provided with flange.
Compared with prior art, the invention has the advantages that：This device can effectively eliminate and produce because of water hammer
The water attack high pressure wave of life, noise, vibration, especially can widely use in high-rise water system, and this equipment and method are pacified
Dress, debugging are convenient, using reliability, the requirement that when meeting the startup of valve snap switch box water pump moment, stopping, water hammer eliminates simultaneously.
The present invention will be further described in detail with reference to the accompanying drawings and detailed description.
Brief description
Fig. 1 is the organigram of the embodiment of the present invention.
In figure：1- outer tube, 11- air cavity, 2- inner tube, 21- through hole, 3- stretches inner bag, 4- shrouding, 5- flange, 6- magnetic valve,
7- pressure gauge, 8- alarm, 9- battery.
Specific embodiment
Embodiment one：As shown in figure 1, a kind of power station fire pump water hammer cancellation element, including outer tube 1 with nested outside
Inner tube 2 in pipe, described outer tube two ends are provided with ring sealing plate 4, so that outer tube, inner tube and shrouding collectively form an airtight gas
Chamber 11, said inner tube outer surface is arranged with the flexible inner bag 3 of tubular, and said inner tube side wall is provided with multiple through holes 21, described outer tube
One end be provided with control inner tube open and close magnetic valve 6, described outer tube is provided with monitoring air cavity air pressure change pressure gauge 7,
Also include a PLC control system being arranged on outer tube lateral wall, alarm 8 and battery 9, described battery controls for PLC
System, alarm and solenoid valve, PLC control system is monitored manometric numerical value and is controlled the fortune of magnetic valve and alarm
Turn.
In the present embodiment, the two ends of described outer tube are provided with flange 5.
During use, this device is arranged on fire hydrant by flange, opens solenoid valve, opens fire hydrant valve, water sprays
When going out, water overflows from interior pipe through-hole, heaves flexible inner bag, eliminates water hammer, once current are too urgent, air cavity internal gas pressure changes
Excessive, beyond pressure gauge pre-set threshold value, after PLC control system receives signal, control alarm equipment alarm, and control magnetic valve to adjust
Amount of restriction, operating personnel can adjust the valve of fire hydrant, it is to avoid hydraulic pressure drastically changes, and damages pipeline.
The foregoing is only presently preferred embodiments of the present invention, all impartial changes done according to scope of the present invention patent with
Modify, all should belong to the covering scope of the present invention.
