Description

technical field [0001] The invention relates to the related field of regulating equipment, in particular to a gravity self-regulating hydraulic pressure stabilizing device. Background technique [0002] The cooling tower system must realize the maximum cooling area utilization operation, which puts forward new requirements for the hardware conditions of the cooling tower. Especially in the cooling tower system during the low and medium load period, because the total operating load does not reach the maximum load of the cooling tower design, the traditional cooling tower is not suitable and the flow rate drops, and part of the cooling area cannot be effectively used. Inability to fully prioritize the use of cooling tower cooling area for operation. [0003] Why can't the area of ​​the cooling tower be fully utilized during low and medium load periods? The main reason is that the cooling tower system is composed of multiple independent cooling towers. When the actual operati...

Problems solved by technology

[0006] The traditional solution is to adjust the initial resistance by adjusting the valves on the water inlet branches. The result is still that the effect is difficult to guarantee. Even if the water resistance bodies of all the branch pipes are adjusted to be consistent, the effect cannot be guaranteed. Because the problem lies in which pipe comes out of the water first, it will cause the above problems

And when the water inlet valve is adjusted, the water outlet resistance on the entire pipeline will be greatly increased, which will increase the energy consumption of the circulation system.

[0007] According to the above situation, a small flow external water resistance adjustment device was invented, but the existing small flow external water resistance adjustment device 1. The volume is large; 2. It is arranged on the upper end of the cooling tower, protruding from the cooling tower, which is easy to cause lightning; 3. It is inconvenient to install and must be installed at the corner, which consumes manpower; 3. When there is a large amount of water, the water resistance is too large, and the energy consumption of the circulation system is high; 4. It cannot solve the problem of negative pressure at the outlet; if the outlet pipe is too long, the effect is not good; 5. 1. The inlet and outlet must be vertical and cannot be installed in horizontal pipes; 6. High installation requirements and poor adaptability (cannot be applied to built-in cooling towers); 7. High cost (in order to overcome the problems of pipeline vibration and wind resistance, high-cost material) is poor in economy, and a gravity self-adjusting hydraulic pressure stabilizing device is now designed to solve the above problems
