Description

Water hammer elimination device for high-rise water pipe

The invention relates to a water hammer elimination device for high-rise water-lifting pipes, in particular to a water-hammer elimination device equipped with electric three-way ball valves for high-rise water-lifting pipes and pumping pipes.

At present, the land in the city is limited, the cost is expensive, and the population is concentrated. Therefore, the buildings are all developing towards high floors, and the relevant water supply pipeline equipment must be more considered.

In general high-rise water supply pipeline equipment, refer to the first and second diagrams. Basically, a high-rise building must be equipped with a reservoir 90 on the bottom floor, while a water supply pool 91 is installed on the top floor of a high-rise building. 90 is connected to two sets of pumping pipes 92 that are used alternately. Each of the two sets of pumping pipes 92 contains at least a pump 93, a check valve 94 and a control valve 95, and is connected to the high-rise pumping pipe 96 with a three-way joint 98. A single pump 93 pumps water through a single set of pumping pipe 92 and control valve 95, and then through the bottom entrance of the high-rise water lift pipe 96 up to the water supply pool 91, and then through the water distribution pipe 97 to supply the residents on each floor respectively. .

The above-mentioned single set of pumping pipeline 92 controlled to start the pump 93 and the control valve 95 to pump the water flow (refer to the solid arrow shown in the first figure) upwards through the pumping pipe 96 into the feed pool 91, when the feed pool 91 When the set water level is reached, the pump will be automatically controlled to turn off 93 At this time, the water flow inside the lifting pipe 96 at a height of tens of meters is impacted downward due to the influence of gravity, but the water hammer absorber 99 cannot fully absorb the water hammer force effectively, so that the water flow (see the dotted arrow shown in the first figure) is still It will impact the check valve 94 downwards, causing severe collisions and noise, and cause the pumping pipe 92 and the water lift pipe 96 to vibrate strongly, thereby rubbing the pipe wall of the building, causing more severe noise, and easily damaging the pipe and its components. Therefore, how to solve the above-mentioned problems is the subject of urgent research for this industry.

The main purpose of the present invention is to use the electric three-way ball valve combination to control the first pump and the second pump connected with the pumping pipeline in an alternating manner.
