TECHNICAL FIELD

[0001] The utility model relates to water conservancy pressure stabilizing equipment technical field, specifically a device for cooling tower balanced water supply. BACKGROUND

[0002] Cooling tower is the water and air flow contact after cold and hot exchange produces steam, steam volatilization takes away heat reaches evaporation heat dissipation, convection heat transfer and radiation heat transfer etc. The principle of industrial or refrigeration air conditioning produces waste heat to reduce water temperature evaporation heat dissipation device. But due to the same set of water pipeline water inlet and outlet between each cooling tower, water body enters the pressure difference of different cooling tower, leading to the water inflow imbalance, some tower water, some water even no water phenomenon, influence cooling tower heat dissipation effect. The conventional method is to set valve at the water inlet of different cooling tower, through the control opening of different cooling tower valve makes the water quantity in each cooling tower keep balanced. This way needs manual according to the change of water pressure to control the opening of valve, operation is more cumbersome. SUMMARY

[0003] To solve the above technical problem, the utility model provides a device for cooling tower balanced water supply.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical scheme and advantages of the utility model more clear, the following will clearly and completely describe the technical scheme of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the range of the utility model.

[0020] The specific embodiments of the present application will be described below with reference to the accompanying drawings:

[0021] As Figures 1-6 As shown in the drawings, a device for cooling tower water balance includes an outer tank 1 and a buffer mechanism 2, the inner part of the outer tank 1 is provided with a detachable buffer mechanism 2, the side of the outer tank 1 is provided with a water outlet pipe 11, and the water outlet pipe 11 is in communication with the cooling tower. The buffer mechanism 2 includes a straight pipe 21 and a storage tank 22, a plurality of drainage holes 213 are arranged on the length direction of the straight pipe 21, and the straight pipe 21 is located in the inner part of the outer tank 1. The top end of the straight pipe 21 extends out of the outer tank 1 and is in communication with the storage tank 22, and the bottom of the straight pipe 21 extends out of the bottom surface of the outer tank 1 and is in communication with the external water pipe through a third flange (212). The water flow flows into the buffer mechanism 2 through the straight pipe 21, then flows into the outer tank 1 from the drainage holes 213, and finally flows into the cooling tower through the water outlet pipe 11. When the water pressure of the water flow flowing into the straight pipe 21 is too large, the liquid level in the straight pipe 21 is higher than that in the outer tank 1, a water column is formed in the straight pipe 21, the water column forms resistance to the water inlet process of the straight pipe 21, and the water inlet amount of the straight pipe 21 is reduced. At this time, the water pressure in the outer tank 1 does not change, so the water amount flowing into the cooling tower remains balanced. When the water inlet amount of the straight pipe 21 increases sharply in a short time, the storage tank 22 can be used to store the sharply increased water amount, prevent the water pressure in the outer tank 1 from sharply increasing, and ensure that the water outlet amount of the outer tank 1 remains constant.

[0022] The outer tank 1 includes a connecting pipe 12 and a tank body 13 in communication with each other, the top of the tank body 13 is provided with the storage tank 22, and the inner diameter of the tank body 13 is greater than that of the connecting pipe 12. The tank body 13 can prevent the liquid level in the outer tank 1 from rising too fast, and improve the liquid level adjusting capacity of the whole lifting device. The top surface of the tank body 13 is provided with a one-way valve 132. When the liquid level in the outer tank 1 exceeds the water outlet pipe 11, the water flow entering the cooling tower from the outer tank 1 will form a vortex and carry away the air in the outer tank 1, so that the air pressure in the outer tank 1 is weakened, the water body enters the outer tank 1 faster, the water outlet amount of the outer tank 1 is changed, and it is not conducive to maintaining the stability of the water outlet amount of the outer tank 1. When the air pressure in the outer tank 1 decreases, the one-way valve 132 can supplement the air outside to the outer tank 1, so that the air pressure in the outer tank 1 is consistent with the outside, thereby maintaining the stable water outlet amount of the outer tank 1.

[0023] The bottom end of the connecting pipe 12 is provided with a first flange 121, and the bottom of the straight pipe 21 is provided with a second flange 211 matched with the first flange 121. The detachable outer tank 1 and the straight pipe 21 facilitate maintenance or replacement of parts. The first flange 121 and the second flange 211 are provided with a sealing ring 122, which improves the sealing performance of the assembly of the straight pipe 21 and the outer tank 1, thereby preventing water leakage. The top of the straight pipe 21 is provided with a positioning ring 214, and the outer tank 1 is provided with a convex groove 131 matched with the positioning ring 214; the top surface of the positioning ring 214 and the convex groove 131 are provided with a sealing gasket 215. The positioning ring 214 helps to quickly determine the relative position of the straight pipe 21 and the outer tank 1, and the sealing gasket 215 can prevent water from leaking out of the assembly gap between the outer tank 1 and the straight pipe 21. The end of the straight pipe 21 close to the storage tank 22 is detachably connected to the storage tank 22 through a fourth flange 23. The detachable straight pipe 21 and the storage tank 22 facilitate maintenance and assembly of parts, and also allow replacement of storage tanks 22 of different capacities to change the water regulating capacity of the device to adapt to actual use conditions.

[0024] The working principle of the specific embodiment of the utility model is as follows: water flow from the outside enters the slow pressure mechanism 2 from the bottom of the straight pipe 21, flows into the outer tank 1 through the drain hole 213, and finally flows into the cooling tower through the water outlet pipe 11. When the water supply pressure suddenly increases, the liquid level in the straight pipe 21 is higher than the liquid level in the outer tank 1, so that the water outlet capacity of the outer tank 1 remains stable.
