Description

Technical Field

[0001] This utility model relates to the field of raw water transmission pipeline technology, and in particular to an intelligent water pressure monitoring and regulation device for raw water transmission pipelines. Background Technology

[0002] Water transmission pipelines are an important component of urban water supply systems. Their function is to transport raw water from water sources to water treatment plants, or purified water from water treatment plants to the distribution network, without undertaking water distribution along the pipeline route. Based on the water transmission method, they can be divided into gravity transmission and pressure transmission. The engineering route selection of water transmission pipelines needs to comprehensively consider factors such as layout rationality and obstacle avoidance. When using water transmission pipelines to transport raw water, the water pressure in the pipelines needs to be monitored and regulated.

[0003] As shown in the reference case "A water supply equipment with water pressure regulation function" announcement number "CN221741438U", by setting up a water pressure regulator and a water pump, the water pressure can be automatically adjusted. When there is a problem with the water pressure, it can adjust itself in a timely manner, reasonably increase or decrease the pressure, and control the water pressure at an appropriate level, which improves the operating efficiency of the device, saves labor costs, and the sterilization device can sterilize and disinfect the water, thus protecting the health of residents to a certain extent.

[0004] According to the above reference materials, the water in the water supply pipe of the above device enters the flow stabilizing box through the inlet. The negative pressure release device is used to eliminate the negative pressure generated during the water supply process. The water pressure regulator automatically controls the pressure of the water pump through the connector, allowing the water pump to pressurize the pressure tank to reach a suitable pressure. The pressure pump in the middle of the base plate is used to pressurize the water supply pipe. However, when the raw water is being transported, impurities and particles in the raw water can easily clog the valve core, affecting the use of the water pressure monitoring and regulation device. It is also inconvenient to clean impurities in the raw water pipeline, reducing the effectiveness of the water pressure monitoring and regulation device. Utility Model Content

[0005] Therefore, it is necessary to provide an intelligent water pressure monitoring and regulation device for raw water transmission pipelines to address the problem of inconvenience in cleaning impurities in the pipelines.

[0006] The device includes two pipes, with a flow regulating valve installed between them. A pressure sensor is installed at the top of one of the pipes, and a filter mechanism is installed at one end of the other pipe. The filter mechanism includes an installation pipe located at one end of the other pipe. Two filter plates are installed on the inner wall of the installation pipe, and a connecting rod is fixedly connected to one end of each of the two filter plates. Installation components are provided at both ends of the installation pipe.

[0007] In one embodiment, the filtering mechanism further includes connecting pipes disposed at both ends of the inner wall of the mounting pipe, wherein one of the connecting pipes is snapped into one end of the inner wall of the mounting pipe, and the other connecting pipe is fixedly connected to the other end of the inner wall of the mounting pipe.

[0008] In one embodiment, one end of one of the connecting tubes is fixedly connected to two retaining rings.

[0009] In one embodiment, two slots are provided at one end of the inner wall of the mounting tube, and the fixing ring is engaged with the inner wall of the slots.

[0010] In one embodiment, pull plates are fixedly connected to both sides of the connecting rod.

[0011] In one embodiment, one end of another of the pipes is fitted with an airbag-type pressure tank.

[0012] In one embodiment, the mounting assembly includes flanges fixedly connected to both ends of the mounting pipe and the pipeline, and a plurality of evenly arranged fixing bolts are provided between the two flanges.

Pull plates on both sides of the connecting rod allow the filter plates to be disassembled for cleaning. The fixing ring and the slot can be used to install one of the connecting pipes, limit the movement of the filter plates, filter impurities in the raw water, and improve the monitoring accuracy of the water pressure monitoring and regulation device.

[0029] The following is combined Figures 1-4 This invention describes an intelligent water pressure monitoring and regulation device for raw water transmission pipelines.

[0030] In one embodiment, the intelligent water pressure monitoring and regulation device for the raw water transmission pipeline includes two pipes 100, with a flow regulating valve 200 installed between the two pipes 100. A pressure sensor 300 is installed at the top of one pipe 100, and a filter mechanism 400 is provided at one end of the other pipe 100. The filter mechanism 400 includes an installation pipe 410 located at one end of the other pipe 100. Two filter plates 420 are installed on the inner wall of the installation pipe 410, and a connecting rod 430 is fixedly connected to one end of each of the two filter plates 420. Installation components 490 are provided at both ends of the installation pipe 410.

[0031] It should be noted that the intelligent water pressure monitoring and regulation device consists of a flow regulating valve 200, a pressure sensor 300, a turbine flow meter, a high-pressure limiting valve, and a control system. When monitoring and regulating the water pressure in the raw water transmission pipeline, the flow regulating valve 200, through the control system, drives the valve to change the cross-sectional area between the valve core and valve seat, controlling the flow rate, temperature, pressure, and other process parameters of the medium in pipeline 100, thus achieving automated regulation. The pressure sensor 300, through a diaphragm at its bottom, detects a slight displacement proportional to the water pressure when water pressure directly acts on the diaphragm, causing a change in the sensor's resistance. This change is detected by electronic circuitry and converted into a standard electrical signal output to monitor the water pressure in the raw water transmission pipeline. Another... The airbag-type pressure tank 480 at one end of pipe 100 allows some working medium to enter the airbag when the system pressure is higher than the pre-charged gas pressure. When the system pressure drops and the pressure of the medium in the system is lower than the gas pressure between the airbag and the tank, the water in the airbag is squeezed out by the gas and replenished into the system, causing the system pressure to rise until the pressure of the working medium in the system is equal to the gas pressure between the airbag and the tank. At this point, the water in the airbag is no longer replenished to the external system, maintaining the water pressure balance in the raw water pipeline. The filter mechanism 400 is installed at one end of one of the pipes 100 and can filter impurities and particulate matter in the raw water, reducing the impact of impurities in the raw water on the use of the flow regulating valve 200 and the pressure sensor 300, without affecting the normal use of the intelligent water pressure monitoring and regulation device.

[0032] like Figure 2 and Figure 3 As shown, the filter mechanism 400 also includes connecting pipes 440 disposed at both ends of the inner wall of the installation pipe 410. One connecting pipe 440 is snapped into one end of the inner wall of the installation pipe 410, and the other connecting pipe 440 is fixedly connected to the other end of the inner wall of the installation pipe 410. One end of one connecting pipe 440 is fixedly connected to two fixing rings 450. One end of the inner wall of the installation pipe 410 is provided with two slots 460. The fixing rings 450 are snapped into the inner wall of the slots 460. Pull plates 470 are fixedly connected to both sides of the connecting rod 430. An airbag-type pressure tank 480 is installed at one end of the other pipe 100.

[0033] In this embodiment, when filtering impurities in the raw water, the connecting pipes 440 at both ends of the installation pipe 410 can be inserted into the inner wall of the pipe 100. The two filter plates 420 and the connecting rod 430 can be engaged with the other end of the inner wall of the installation pipe 410. One of the connecting pipes 440 is engaged in the slot 460 through the fixing ring 450, which can limit the filter plate 420. During installation, one of the connecting pipes 440 will squeeze the fixing ring 450, causing the fixing ring 450 to deform. One of the connecting pipes 440 can move to a suitable position and be embedded in the slot 460, which can filter impurities and particulate matter in the raw water and improve the performance of the water pressure monitoring and regulation device.

[0034] like Figure 4 As shown, the mounting assembly 490 includes flanges 491 fixedly connected to both ends of the mounting pipe 410 and the pipe 100. A plurality of evenly arranged fixing bolts 492 are provided between the two flanges 491. Sealing rings 493 are provided on both sides of the mounting pipe 410, and one of the sealing rings 493 is provided between the other pipe 100 and the mounting pipe 410.

[0035] In this embodiment, when monitoring and adjusting the water pressure of the raw water pipeline, the installation pipe 410 is aligned with the flange 491 at one end of one of the pipes 100 through the flange 491 at one end, and the installation pipe 410 is installed by fixing bolts 492. The sealing rings 493 at both ends of the installation pipe 410 can improve the sealing between the installation pipe 410 and the pipe 100, improve the filtration effect of the device on the raw water, and improve the monitoring accuracy of the water pressure monitoring device.

[0036] Working principle: The installation pipe 410 is connected to the flange 491 of one of the pipes 100 via a flange 491 at one end, and then fixed with multiple fixing bolts 492. One end of one connecting pipe 440 is inserted into the other pipe 100. Two filter plates 420 are engaged with the connecting rod 430 and snapped into the installation pipe 410. The other connecting pipe 440 uses two fixing rings 450 to fit into the slots 460 to limit the position of the filter plates 420. The two filter plates 420 can filter impurities in the raw water, preventing... To prevent impurities in the raw water from damaging the flow regulating valve 200 and pressure sensor 300, the flow regulating valve 200 and pressure sensor 300 can monitor and regulate the water pressure in the raw water pipeline. When the water pressure in the pipeline is greater than the pressure of the pre-filled gas, some working medium will enter the air bladder of the air bladder 480. When the pressure in the pipeline drops and the pressure of the medium in the pipeline is lower than the gas pressure between the bladder and the tank, the water in the air bladder will be squeezed out by the gas and replenished into the system to maintain the water pressure balance in the raw water pipeline.

[0037] It should be noted that the flow regulating valve 200, pressure sensor 300, and airbag pressure tank 480 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs, and the specific power supply method can be selected according to the situation, which will not be elaborated here.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
