Description

Technical Field

[0001] The present application relates to the technical field of secondary water supply, and in particular to an automatic damping pipe network superimposed water supply device. Background Art

[0002] Secondary water supply refers to the form in which units or individuals store and pressurize urban public water supply or self-built facilities water supply, and then supply it to users or for their own use through pipelines. Secondary water supply is mainly established to compensate for the lack of pressure in municipal water supply pipelines and to ensure water supply for people living and working in high-rise areas.

[0003] Most of the current secondary water supply equipment for municipal pipe networks uses split-chamber differential compensation non-negative pressure water supply equipment, that is, a constant pressure chamber at one end and a high pressure chamber at the other end, and the purpose of compensation is achieved through the energy storage of the high pressure chamber. However, in actual application, the so-called constant pressure chamber is actually a pipe that directly penetrates through the tank body and is connected to the main water inlet pipe of the equipment. The high pressure chamber is an empty tank body and does not play a pressure buffering role at all.

[0004] With respect to the above-mentioned related technologies, the inventors believe that in the existing chamber-type differential compensation non-negative pressure water supply equipment, the gas in the high-pressure chamber will enter the user's pipeline network together with the compensation water, making the user's pipeline network unstable. Summary of the invention

[0005] In order to improve the problem of unstable pressure in the user's water supply network, the present application provides an automatic damping network superimposed water supply equipment.

[0019] Optionally, the bypass water inlet pipe is sequentially connected with a backflow suppression valve and a bypass water inlet end inspection valve.

[0020] By adopting the above technical solution, the backflow suppression valve set up can prevent the water in the automatic damping pressure stabilizing regulating tank from flowing back into the municipal water pipe.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-2 This application is described in further detail.

[0034] The present application embodiment discloses an automatic damping pipe network superimposed water supply device. Figure 1 An automatic damping pipe network superimposed water supply device includes a water supply unit 1 for supplying water to users and a municipal water pipe 2 connected to the water supply unit 1. The water transported by the municipal water pipe 2 is pressurized by the water supply unit 1 before being supplied to the user, ensuring that the water received by the user end is always under a certain pressure, avoiding unstable pressure during water use.

[0035] Reference Figure 1 and Figure 2The water supply unit 1 includes an equipment water inlet main pipe 11, an equipment water outlet main pipe 12 and a booster device 13 connected and arranged therebetween. The equipment water inlet main pipe 11 is connected to the municipal water pipe 2, and the equipment water outlet main pipe 12 is connected to the user end. The booster device 13 is provided with multiple groups between the equipment water inlet main pipe 11 and the equipment water outlet main pipe 12. The booster device 13 includes a pump water inlet inspection valve 131, a booster pump group 132 and a pump water outlet inspection valve 133. The pump water inlet inspection valve 131, the booster pump group 132 and the pump water outlet inspection valve 133 are interconnected through a pipeline. The pump water inlet inspection valve 131 is connected to the equipment water inlet main pipe 11, the pump water outlet inspection valve 133 is connected to the equipment water outlet main pipe 12, and the booster pump group 132 is connected to the pump water inlet inspection valve 131 and the pump outlet Between the water inspection valve 133, in the process of supplying water to users, the water transported in the municipal water pipe 2 enters the water supply unit 1 through the equipment water inlet main pipe 11, and then passes through the pump water inlet inspection valve 131, the booster pump group 132 and the pump water outlet inspection valve 133 in sequence, and is finally supplied to users by the equipment water outlet main pipe 12. The booster pump group 132 arranged inside the water supply unit 1 can play a role of boosting, so that the user end can receive the supplied water with a certain pressure, and can prevent the pressure from being unstable during the water delivery process; when the booster pump group 132 fails, the pump water inlet inspection valve 131 and the pump water outlet inspection valve 133 can cut off the pipeline between the equipment water inlet main pipe 11 and the equipment water outlet main pipe 12, so as to facilitate the staff to inspect and maintain the booster pump group 132.

[0036] Furthermore, a water outlet check valve 134 is provided between the booster pump group 132 and the pump water outlet inspection valve 133. The water outlet check valve 134 can prevent the water in the equipment water outlet main pipe 12 from flowing back through the booster pump group 132, thereby avoiding damage to the booster pump group 132.

[0037] Reference Figure 1 and Figure 2 An electric regulating valve 21 is connected to the municipal water pipe 2. During the water supply process, the electric regulating valve 21 can automatically control the opening and closing of the electric regulating valve 21 according to the water pressure in the municipal water pipe 2. An electric front-end inspection valve 22 and an electric rear-end inspection valve 23 are symmetrically connected at both ends of the electric regulating valve 21. Since the electric regulating valve 21 is a precision component of electric control, it is particularly prone to failure after long-term use. When a failure occurs, the staff can close the electric front-end inspection valve 22 and the electric rear-end inspection valve 23 at the same time, and then remove the electric regulating valve 21 from the municipal water pipe 2 for easy inspection and maintenance.

[0038] An automatic damping pressure stabilizing regulating tank 3 is connected in parallel to the municipal water pipe 2, and the automatic damping pressure stabilizing regulating tank 3 is connected in parallel with the electric front-end inspection valve 22, the electric regulating valve 21 and the electric rear-end inspection valve 23, and a bypass water inlet pipe 4 and a bypass water outlet pipe 5 are connected to the automatic damping pressure stabilizing regulating tank 3. During operation, water in the municipal water pipe 2 can enter the automatic damping pressure stabilizing regulating tank 3 through the bypass water inlet pipe 4, and then flow out from the bypass water outlet pipe 5 and flow back into the bypass water outlet pipe 5. To the municipal water pipe 2, the electric front-end inspection valve 22, the electric regulating valve 21 and the electric rear-end inspection valve 23 are located between the bypass water inlet pipe 4 and the bypass water outlet pipe 5; an energy releaser is arranged inside the automatic damping and voltage-stabilizing regulating tank 3. When the pressure in the municipal water pipe 2 is insufficient, the opening and closing size of the electric regulating valve 21 on the municipal water pipe 2 is adjusted, and the automatic damping and voltage-stabilizing regulating tank 3 will use the energy releaser to merge the water inside it and the municipal water pipe 2 into the water supply unit 1.

[0039] Reference Figure 1 and Figure 2 A backflow suppression valve 41 and a bypass water inlet end inspection valve 42 are connected to the bypass water inlet pipe 4 in sequence, and a bypass water outlet pipe 5 valve and a pressure regulating valve 52 are connected to the bypass water outlet pipe 5 in sequence. The set backflow suppression valve 41 can prevent the water in the automatic damping pressure stabilizing regulating tank 3 from flowing back into the municipal water pipe 2. When the automatic damping pressure stabilizing regulating tank 3 needs to be overhauled as a whole, the staff can close the bypass water inlet pipe 4 inspection valve to overhaul the automatic damping pressure stabilizing regulating tank 3; the set bypass water outlet pipe 5 valve can control the on-off of the bypass water outlet pipe 5, and is used in conjunction with the bypass water inlet pipe 4 inspection valve to overhaul the automatic damping pressure stabilizing regulating tank 3. The set pressure regulating valve 52 can regulate the water pressure flowing from the bypass water outlet pipe 5 to the municipal water pipe 2.

[0040] The municipal water pipe 2 is respectively connected with an inlet side pressure transmitter 7 and an outlet side pressure transmitter 8. The inlet side pressure transmitter 7 is located at the front end of the bypass inlet pipe 4, and the outlet side pressure transmitter 8 is located at the rear end of the bypass outlet pipe 5. The inlet side pressure transmitter 7 and the outlet side pressure transmitter 8 can monitor the water pressure on the municipal water pipe 2 in real time, making it convenient for the staff to adjust and control.

[0041] Reference Figure 1 and Figure 2The energy releaser includes a membrane structure 31 arranged inside the automatic damping and voltage-stabilizing regulating tank 3 and an inflating device 32 arranged on the outer wall of the automatic damping and voltage-stabilizing regulating tank 3. The membrane structure 31 is made of rubber material, and the membrane structure 31 is a cylindrical cavity with a hollow interior. The interior of the membrane structure 31 is respectively connected with the bypass water inlet pipe 4 and the bypass water outlet pipe 5. Therefore, the interior of the membrane structure 31 can be filled with water transported in the municipal water pipe 2; the membrane structure 31 and the inner wall of the automatic damping and voltage-stabilizing regulating tank 3 do not contact each other, and can form an energy storage space 33 for storing gas. The inflating device 32 can fill the energy storage space 33 with high-pressure gas. When the water pressure of the municipal water pipe 2 is insufficient, under the action of the high-pressure gas in the automatic damping and voltage-stabilizing regulating tank 3, the gas inside the membrane structure 31 can flow into the municipal water pipe 2 to make up for the problem of insufficient pressure in the municipal water pipe 2.

[0042] Furthermore, an inspection hole 34 connected to the interior of the automatic damping and voltage-stabilizing regulating tank 3 is opened on the side wall, and a cover plate is detachably fixedly connected to the inspection hole 34. During the water supply process, if the membrane structure 31 leaks or the gas filling in the energy storage space 33 fails, the inspection hole 34 can facilitate the staff to inspect the interior of the automatic damping and voltage-stabilizing regulating tank 3.

[0043] Reference Figure 1 and Figure 2 A high-energy reflux pipe 6 is connected to the equipment water outlet main pipe 12, and one end of the high-energy reflux pipe 6 away from the water supply unit 1 is connected to the bypass water outlet pipe 5. When the internal pressure of the municipal water pipe 2 is insufficient, a part of the water pressurized by the water supply unit 1 flows into the bypass water outlet pipe 5 through the high-energy reflux pipe 6, thereby increasing the pressure of the water flowing out from the automatic damping pressure stabilizing regulating tank 3; an energy switching valve 61 is connected to the high-energy reflux pipe 6, which can control the on and off of the high-energy reflux pipe 6. When the pressure of the municipal water pipe 2 is insufficient, the energy switching valve 61 can be controlled to open, otherwise it is not necessary.

[0044] The working process of an automatic damping pipe network superimposed water supply device in the embodiment of the present application is as follows: when the water pressure and water volume of the municipal water pipe 2 are sufficient, the electric regulating valve 21 is in a fully open state, and the water supply unit 1 mainly supplies water from the municipal water pipe 2. Finally, the water required by the user is superimposed by the water supply unit 1 and supplied to the user. At the same time, the municipal water pipe 2 box is connected in parallel in the automatic damping pressure stabilizing regulating tank 3 before and after the electric regulating valve 21 to fill and store water; when the water volume of the municipal water pipe 2 is less than that of the user, the electric regulating valve 21 is turned on and the water is turned off. When the water volume is low, the electric regulating valve 21 will automatically adjust the opening of the electric regulating valve 21 according to the pressure. At the same time, the automatic damping and voltage-stabilizing regulating tank 3 will automatically pressurize the water in the automatic damping and voltage-stabilizing regulating tank 3 through the energy releaser to supply water to the user; when the pressure of the municipal tap water is lower than the minimum service allowable pressure lower limit, the electric regulating valve 21 is closed and the water supply unit 1 stops running; when the water pressure in the municipal water pipe 2 returns to normal, the water supply unit 1 automatically starts running and supplies water to the user again.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
