Device.Cold and hot exchange is carried out after being contacted using water with air flow and produces steam, heat is taken away in steam volatilization, and cooling tower utilizes steaming
Diverging heat, convection heat transfer' heat-transfer by convection and radiation turn the principles such as heat, to disperse caused waste heat in industrial or refrigeration air-conditioner, to reduce water temperature
Evaporating radiator.Due to cooling tower in use, its cooling water meeting evaporating loss, if cooling tower supplies water not
Foot, the meeting prediction occurring report of cold equipment or shutdown, therefore need to carry out moisturizing to cooling tower in time, to ensure the normal fortune of system
OK.
Cooling tower automatic water supplement at present more uses mechanical float ball water compensating valve to realize automatic water supplement control, surpasses when the water surface declines
When crossing preset value, ball-cock assembly is opened, and piston upper chamber chamber pressure reduces, and piston forms pressure difference up and down, in this differential pressure action lower Disc
Opening is supplied water；When water level rises to preset height, ball float valve closure, piston upper chamber chamber pressure constantly increase causes flap
Closing stops supplying water.And so on automatic controlling liquid level realizes automatic water-supply function in setting height.But when cooling tower is arranged on
A high position, tap water pressure are not enough to cooling tower moisturizing, it is necessary to using water pump pressurization moisturizing, due to water in cooling tower water accumulating disc
Position difference of height is small, is difficult to stably control water pump start and stop using cooling tower water pond water level control, generally require separately to set water supply tank and
Fluid level control device etc. is realized, sometimes by condition bad realization now, not only investment increase, is also brought not to installation maintenance
Just.
Therefore it provides it is a kind of small suitable for water level difference of height in cooling tower water accumulating disc, and cost of investment is low, and it is easy to reality
The cooling tower water replanishing device of now accurate quick moisturizing, has been a good problem to study.

Lean on, be convenient for installation and maintenance, suitable for various occasions；Flexible arrangement, do not limited by height；Complete constant pressure water compensation apparatus, construction
When need to only connect water power exterior tubing can, it is convenient and swift.
Brief description of the drawings
Fig. 1 is constructional device figure of the present utility model；
It is in figure：Cooling tower 1, ball-cock assembly 2, suction small pump 3, pressure switch 4, diaphragm pressure tank 5, electrical control cabinet 6,
Soft fitting 7, butterfly valve 8, ball valve 9.
Embodiment
Below in conjunction with the accompanying drawings, the utility model is described further：
As shown in figure 1, cooling tower level pressure automatic water-replenishing device, including cooling tower 1, cooling tower 1 pass through medium water conduit 10
Medium water source is connected, is provided with the ball-cock assembly 2 in WATER AS FLOW MEDIUM in described cooling tower 1, while be provided with the low water of WATER AS FLOW MEDIUM
Bit line L and high-water line H；Medium water conduit ball valve 9 is provided with described medium water conduit 10 and including the He of diaphragm pressure tank 5
The water replanishing device sucked including small pump 3；
Described water replanishing device includes the suction small pump 3 being arranged on medium water conduit 10, and is arranged on suction and mends
The soft fitting 7 and butterfly valve 8 of the both sides of water pump 3；Described suction small pump 3 connects electrical control cabinet 6, electrical control cabinet 6 while connection position
Pressure switch 4 between diaphragm pressure tank 5 and suction small pump 3；
Described suction small pump 3, soft fitting 7 and butterfly valve 8 is provided with two sets of pipe-line systems parallel with one another, mutual conduct
It is standby.
There is water replanishing device ball-cock assembly 2 in the cooling tower 1；When the water level decreasing of cooling tower 1 is to L, ball-cock assembly 2 is with water level
Decline main valve and open feedwater, when water level rises to H, ball-cock assembly 2 is closed as water level rises main valve stops feedwater.
The small pump 3, a preparation and a use, WATER AS FLOW MEDIUM pass sequentially through soft fitting 7, butterfly valve 8 and suction small pump 3 and flow into cooling
In tower 1.
The pressure switch 4, between suction small pump 3 and diaphragm pressure tank 5.Pressure switch 4 and small pump 3
Control is connected with electrical control cabinet 6.Pressure switch 4 will directly display the pressure of cooling tower 1, when its pressure is less than setting minimum pressure
When, pressure switch 4 will transmit a signal to small pump 3, the start-up operation moisturizing of small pump 3；When its pressure is more than, maximum pressure is set
When, pressure switch 4 will transmit a signal to small pump 3, and small pump 3 stops moisturizing.
The diaphragm pressure tank 5, after small pump 3 is stopped, the pressure of cooling tower 1 is mended by diaphragm type pressurized tank 5
Repay, when the pressure of cooling tower 1 declines, the gas in diaphragm type pressurized tank 5 is wanted to expand naturally, and the water in tank body is in gas pressure
Fill into automatically in cooling tower 1 down；When in diaphragm type pressurized tank 5 water reduce to a certain extent, by small pump 3 come realize supercharging,
