Technical Field

[0001] The utility model belongs to the technical field of water supply, and specifically relates to a non-negative pressure compensator. Background Art

[0002] Water supply is a concept involving many aspects, including water supply system, water supply equipment, etc.

[0003] Among them, water supply equipment includes water supply pipes. When water consumption suddenly increases, there is an imbalance between water pumping and water inflow from the pipe network, system leakage, insufficient water supply from high-level water tanks or water towers, negative pressure is likely to occur in the water supply pipes. The appearance of negative pressure can easily lead to water quality damage, equipment damage, water supply interruption, etc. At this time, a non-negative pressure compensator is needed;

[0004] Among them, the non-negative pressure compensator is to realize the function of no negative pressure in the water supply pipe. The non-negative pressure compensator includes a flow stabilizing compensator, also known as a flow stabilizing tank. At present, the rise of tourism in small towns has led to a large difference in water supply demand between holidays and daily towns. During daily water supply in towns, the water supply demand is small and generally there will be no negative pressure in the pipe. At this time, the non-negative pressure compensator will not be used for a long time, and the water in the flow stabilizing tank will breed bacteria if it is not used for a long time.

[0005] In order to solve the above problems, a negative pressure-free compensator is proposed in the present application. Utility Model Content

[0011] The swirl pot is provided with an auxiliary component for knowing whether the water in the swirl pot is full.

[0012] The top of the turbulence tank is connected to a water inlet pipe, on which a first solenoid valve is arranged. The water inlet pipe is arranged to fill water into the turbulence tank. The first solenoid valve is arranged to facilitate control of whether the water inlet pipe is unobstructed.

[0013] There are multiple nozzles, and the multiple nozzles are divided into four groups, and every two groups of nozzles are respectively installed on corresponding delivery pipes. By providing multiple nozzles, it is helpful to flush the inner wall of the simmering tank more intensively.

[0014] The disinfection box is connected with a liquid adding pipe, and a sealing cover is threadedly connected to the liquid adding pipe. By arranging the liquid adding pipe and the sealing cover, it is convenient to add liquid into the disinfection box.

One end of the water pipe 505 located in the disinfection box 503 is close to the inner bottom wall of the disinfection box 503. The output end of the water pump 504 is connected to a manifold 506. Both ends of the manifold 506 away from the water pump 504 are connected to delivery pipes 507. Both delivery pipes 507 are equipped with nozzles 508. First, the second solenoid valve 4 is used to drain the water from the water outlet pipe 3. The inner wall of the simmering tank 2 is blocked, and then the water pump 504 is started to input the disinfectant in the disinfection box 503 into the manifold 506 through the water pipe 505, and then the manifold 506 inputs it into the delivery pipe 507, and finally sprays it to the inner wall of the simmering tank 2 through the nozzle 508, which is used to flush and disinfect the inner wall of the simmering tank 2.

[0039] Reference Figure 1 and Figure 3In order to fully rinse the inner wall of the simmering pot 2 and minimize the residual disinfectant, it is necessary to fill the simmering pot 2 with water multiple times. For this purpose, an auxiliary component 6 is provided on the simmering pot 2 to know whether the water in the simmering pot 2 is full. The auxiliary component 6 includes a U-shaped tube 601 connected to the simmering pot 2 and an alarm 607 installed on the simmering pot 2. A fourth solenoid valve 602 is provided on the U-shaped tube 601. A contact switch 606 is provided in the U-shaped tube 601. A filter screen 603 is installed in the U-shaped tube 601. A float 604 is placed on the top of the filter screen 603. The float 604 is located directly below the contact switch 606. The contact The switch 606 is electrically connected to the alarm 607. The drain pipe 501 is blocked by starting the third solenoid valve 502. As clean water is flushed into the simmering pot 2 through the water inlet pipe 201, the simmering pot 2 is gradually filled. After that, the water gradually enters the U-shaped tube 601. The water passes through the filter 603, causing the float 604 to gradually float up. Finally, it touches the contact switch 606, which controls the alarm 607 to sound, thereby reminding the staff to stop injecting water. Then, the third solenoid valve 502 is started again to unblock the drain pipe 501. By filling the simmering pot 2 with water and discharging it multiple times, the effect of flushing the simmering pot 2 is achieved.

The circuit connection method of the two can be reasonably set according to actual conditions, and the signal transmission method of the two is the existing technology.

[0043] Working principle:

[0044] The negative pressure-free compensator first uses the second electromagnetic valve 4 to block the water outlet pipe 3, and then starts the water pump 504 to input the disinfectant in the disinfection box 503 into the manifold 506 through the water delivery pipe 505, and then the manifold 506 inputs it into the delivery pipe 507, and finally sprays it to the inner wall of the simmering tank 2 through the nozzle 508, which is used to flush and disinfect the inner wall of the simmering tank 2. At the same time, the third electromagnetic valve 502 is started to make the drain pipe 501 unobstructed. At this time, the waste liquid in the simmering tank 2 is gradually discharged into the water outlet pipe 3, and then discharged into the drain pipe 501, and finally discharged from the drain pipe 501, thereby achieving the effect of disinfecting and sterilizing the simmering tank 2. Afterwards, water is injected into the simmering tank 2 through the water inlet pipe 201, and the disinfectant in the simmering tank 2 is flushed clean with water, thereby avoiding the residue of disinfectant in the simmering tank 2 as much as possible, thereby achieving the effect of facilitating the injection of clean water into the simmering tank 2, and avoiding the water that breeds bacteria from flushing into the water supply pipe as much as possible.

[0045] The negative pressure-free compensator blocks the drain pipe 501 by starting the third solenoid valve 502. As clean water rushes into the turret tank 2 through the water inlet pipe 201, the turret tank 2 is gradually filled. After that, the water gradually enters the U-shaped tube 601. The water passes through the filter screen 603, causing the float 604 to gradually float up. Finally, it touches the contact switch 606, which controls the alarm 607 to sound, thereby reminding the staff to stop injecting water, and then start the third solenoid valve 502 to unblock the drain pipe 501. By filling the turret tank 2 with water and discharging it multiple times, the effect of flushing the turret tank 2 is achieved.
