[0002] As the lifeline of a city, the stability and efficiency of the water supply system are of paramount importance. In the daily maintenance of water supply pipelines, it is especially important to quickly and accurately investigate and repair problems such as reduced water pressure in residents' homes caused by hidden leaks or air blockages.

[0003] When checking for low water pressure in traditional water supply pipes, maintenance personnel usually use a flexible hose pressure gauge to measure the pressure. However, due to the variety of specifications of water supply pipes, conventional flexible hose pressure gauges often have fixed connectors and lack adapters, making them unsuitable for different specifications of water supply pipes and reducing their applicability. In addition, conventional flexible hose pressure gauges cannot effectively vent air, which makes the measured pressure values ​​easily affected, and they are also inconvenient to operate.

[0004] Therefore, we provide a novel water supply and exhaust pressure measuring device. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned technical problems by providing a novel water supply and venting pressure measuring device that can adapt to water supply pipes of different specifications and effectively vent air.

[0014] 1.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Example: A novel water supply and exhaust pressure measuring device, such as Figures 1-4 As shown, the device includes a pressure gauge 1, a pressure buffer tube 2 installed at the lower end of the pressure gauge 1, a quick-opening ball valve 3 installed at the lower end of the pressure buffer tube 2, an L-shaped connecting pipe installed at the lower end of the quick-opening ball valve 3, a tee connector 4 connected to the quick-opening ball valve 3 through the L-shaped connecting pipe, a connecting pipe 5 installed at one end of the tee connector 4, an automatic air vent valve 6 installed at the upper end of the connecting pipe 5, a corrugated hose 7 installed at the other end of the tee connector 4, and a multi-functional adapter 8 connected to the end of the corrugated hose 7 away from the tee connector 4.

[0026] All components inside the exhaust pressure testing device are connected and secured by threaded connections. Sealing PTFE tape is wrapped around the connection points of two components to further prevent water leakage. All components are designed to be through-through to ensure water flow and detection.

[0027] Pressure gauge 1 uses a high-precision digital pressure gauge, which can display the pressure value in real time and effectively observe whether the pressure inside the water supply pipe meets the standard.

[0028] The pressure buffer pipe 2 adopts a spiral coil design, which can effectively buffer water pressure fluctuations.

[0029] The quick-opening ball valve 3 has a handle on its outer surface. By rotating the handle, the quick-opening ball valve 3 can be quickly opened and closed, making it easy to operate.

[0030] The automatic air vent valve 6 has a float ball at its vent position. The float ball can control the opening and closing of the vent port of the automatic air vent valve 6. The automatic air vent valve 6 is located at the top of the device.

[0031] The external end of the multi-functional adapter 8 includes multiple external thread interfaces of different specifications, which can be used to connect water supply pipes of different diameters.

[0032] When inspecting for issues such as reduced water supply pipeline pressure, firstly, select the appropriate multi-functional adapter 8 based on the different pipe diameters of the water supply pipeline. Then, rotate the multi-functional adapter 8, and install and fix the corrugated hose 7 to the multi-functional adapter 8 based on the threaded connection of the components. Next, connect the outer end of the multi-functional adapter 8 to the water supply pipeline. At the same time, the handle on the quick-opening ball valve 3 is in the closed state. Therefore, the water flow inside the water supply pipeline will enter the tee connector 4 through the corrugated hose 7. Because the quick-opening ball valve 3 is in the closed state, the water flow inside the tee connector 4 will enter the automatic air release valve 6 along the connecting pipe 5. Before the water flow enters the automatic air release valve 6, due to the fact that the density of air is less than that of water, the air moves upward due to buoyancy, causing... The air must always be above the water flow, and the automatic air vent 6 is located at the highest point of the equipment. Air from the water supply pipe first enters the automatic air vent 6 through the connecting pipe 5. The air gradually accumulates at the upper part of the automatic air vent 6. Under the pressure of the air, the float inside the automatic air vent 6 moves downwards. During this movement, the vent on the automatic air vent 6 is open, and the air inside the automatic air vent 6 is discharged outwards along the vent. When all the air in the water supply pipe is discharged, water flows into the automatic air vent 6. As the water flows into the automatic air vent 6, the float rises under the buoyancy of the water. As the float rises, it blocks the vent on the automatic air vent 6. With the vent closed, liquid will not flow out of the automatic vent valve 6, thus venting the air from inside the water supply pipe. When the automatic vent valve 6 stops venting, the quick-opening ball valve 3 is opened by rotating the handle on its exterior. At this time, water will flow along the quick-opening ball valve 3 into the pressure buffer pipe 2, and then into the pressure gauge 1. The pressure value displayed on the pressure gauge 1 allows observation of the pressure inside the water supply pipe after venting. The use of the multi-functional adapter 8 enriches the device's diverse application scenarios and hierarchical functions, making the pressure measurement process more flexible and convenient, greatly improving the efficiency of on-site judgment and problem solving. Furthermore, the multi-functional adapter 8 offers a variety of specifications for quick adaptation. The ability to accommodate water supply pipes of different specifications significantly expands the applicability of the device. With the assistance of pressure gauge 1, pressure buffer pipe 2, quick-opening ball valve 3, and automatic air vent valve 6, maintenance personnel can easily purge air from the corrugated hose 7 using the automatic air vent valve 6. Pressure gauge 1 allows for precise observation of whether the pressure inside the water supply pipe has returned to normal, ensuring the accuracy of the pressure readings. Furthermore, the device is simple and convenient to operate, further improving the efficiency of on-site testing. Through the coordinated operation of all components, the device can quickly obtain firsthand pressure data. By comparing and analyzing multiple data points, it can accurately determine whether the problem is caused by air blockage or a hidden leak in the pipe, allowing for the immediate development and implementation of an effective emergency repair plan, greatly shortening repair time.This reduces the impact on users' lives and fundamentally ensures the safety and stability of the urban water supply system, providing urban residents with more reliable and convenient water supply services.

[0033] Working Principle: When inspecting for issues such as reduced water supply pipeline pressure, firstly, select the appropriate multi-functional adapter 8 according to the different pipe diameters of the water supply pipeline. Then, rotate the multi-functional adapter 8, and install and fix the corrugated hose 7 to the multi-functional adapter 8 based on the threaded connection of the components. Next, connect the outer end of the multi-functional adapter 8 to the water supply pipeline. At the same time, the handle on the quick-opening ball valve 3 is in the closed state. Therefore, the water flow inside the water supply pipeline will enter the tee connector 4 through the corrugated hose 7. Because the quick-opening ball valve 3 is in the closed state, the water flow inside the tee connector 4 will enter the automatic air vent valve 6 along the connecting pipe 5. Before the water flow enters the automatic air vent valve 6, due to the fact that the density of air is less than that of water, the air moves upward due to buoyancy, so that the air is always above the water flow. Furthermore, the automatic air vent valve 6 is located at the highest point of the equipment. The air inside the water supply pipeline will first enter the automatic air vent valve 6 through the connecting pipe 5, and then the air gradually accumulates at the upper end of the automatic air vent valve 6. Under the pressure of air, the float inside the automatic air vent valve 6 moves downwards. During this movement, the vent port on the automatic air vent valve 6 is open, and the air inside the valve 6 is discharged outwards along the vent port. When all the air inside the water supply pipe is discharged, water flows into the automatic air vent valve 6. As the water flows into the valve 6, the float inside rises under the buoyancy of the water. As the float rises, it blocks the vent port on the automatic air vent valve 6, closing it and preventing liquid from flowing out. This completes the discharge of air from the water supply pipe. When the automatic air vent valve 6 stops discharging air, the quick-opening ball valve 3 is opened by rotating the handle on its exterior. At this time, the water flows into the pressure buffer pipe 2 along the quick-opening ball valve 3 and then into the pressure gauge 1. The pressure value displayed on the pressure gauge 1 indicates the pressure inside the water supply pipe after the air discharge.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
