[0002] In the construction of spring water direct drinking projects, the design and installation of drinking water pipelines are of vital importance, especially the inlet pipe part. The inlet pipe refers to the connecting pipe section between the outdoor water supply network and the indoor water supply network, generally known as the household pipe. The drinking water pipeline needs to ensure the purity of the water quality, while also ensuring the safety and stability of the pipeline system.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. The present invention is further described in detail below in conjunction with the accompanying drawings.

[0026] A terminal exhaust device for drinking water pipeline in spring water direct drinking project construction, such as Figure 1-4 As shown, it includes an outdoor water supply pipe 01, a ball valve 02, an inlet pipe 03 and an exhaust pipe 04. The outdoor water supply pipe 01 is connected to the inlet pipe 03 through the ball valve 02. The exhaust pipe 04 is vertically installed on the outer surface of the inlet pipe 03. The exhaust valve is detachably installed on the exhaust pipe 04. The exhaust valve includes an air inlet inner tube 1 and an air outlet outer tube 2. The air outlet outer tube 2 is sleeved on the air inlet inner tube 1. The air outlet outer tube 2 is detachably installed on the exhaust pipe 04. The non-opening part of the air inlet inner tube 1 is fixedly connected to the isolation layer 3 through a plurality of connecting columns 4. The air inlet inner tube 1, the air outlet outer tube 2 and the isolation layer 3 are all axially penetrated with a floating plugging device. The impurity particles in the external gas reflux are isolated through the isolation layer 3. A filter cotton layer is provided in layer 3 to isolate impurities on the filter cotton layer to avoid contamination of drinking water. The exhaust valve can effectively balance the air pressure inside and outside the pipeline to ensure smooth water flow and avoid the impact of gas in the pipeline on the pipeline network. At the same time, through the setting of the isolation layer 3 and the filter surface layer, external impurities can be effectively prevented from entering the drinking water system, the quality and safety of drinking water can be guaranteed, and safe exhaust can be performed. The detachable setting of the exhaust valve facilitates repair and maintenance, thereby improving the reliability and service life of the system. A number of circular through holes are opened on the isolation layer 3 for easy ventilation. The entire device can be easily disassembled and decomposed, and the filter cotton layer in the isolation layer 3 can be quickly replaced.

[0027] The air outlet outer tube 2 includes an air outlet tube 21 and a cone 22. The cone 22 is detachably installed at the opening of the air outlet tube 21. One end of the air outlet tube 21 with the cone 22 installed is threadedly connected to the exhaust pipe 04. The other end of the air outlet tube 21 is provided with a plurality of air outlets. The air inlet inner tube 1 and the isolation layer 3 are both located between the air outlet tube 21 and the cone 22. The cone 22 is clamped to the air inlet inner tube 1. The cone 22 includes a first bottom surface and a second bottom surface. The area of ​​the first bottom surface is larger than that of the second bottom surface. The first bottom surface is threadedly connected to the opening of the air outlet tube 21. The cone 22 and the air outlet tube 21 are both penetrated by the guide rod 6. A circular groove is provided on the cone 22, and the circular groove is adapted to the air inlet tube 11. , it is connected with the air inlet cylinder 11 through the card slot, and the closed installation is completed to prevent the gas from leaking without the air inlet cylinder 11. A protruding circular inner wall is provided on the first bottom surface of the cone 22, and a thread is provided on the circular inner wall, which is threadedly connected with the inner wall of the air outlet cylinder 21, and a force groove is opened on the cone 22, which is convenient for the staff to have a good focus when twisting. The diameter of the isolation layer 3 is the same as the inner diameter of the air outlet cylinder 21. The isolation layer 3 is tightly connected with the air outlet cylinder 21 to prevent the external reflux gas from directly entering the drinking water pipeline without the isolation layer 3. The diameter of the first bottom surface of the cone 22 is directly the same as that of the air outlet cylinder 21. When the card connection is completed, the cone 22 is located at the end face of the opening of the air outlet cylinder 21.

[0028] The air intake inner cylinder 1 includes an air intake cylinder 11 and sound-absorbing cotton 12. The sound-absorbing cotton 12 covers the air intake cylinder 11 through a plurality of clamps 7. The non-opening part of the air intake cylinder 11 is fixedly connected to the isolation layer 3 through a plurality of connecting columns 4. The frustum 22 clamps the air intake cylinder 11. A plurality of through holes are opened on the side of the air intake cylinder 11. The through holes are square holes with a large filtering area and a large flow rate. When the gas passes through the air intake cylinder 11, the square through holes will guide and turn the wind flow and further slow down its speed, thereby effectively alleviating the impact and turbulence caused by the sudden change in flow rate, so that the gas can fully contact and pass through the sound-absorbing cotton 12, so that it can effectively absorb and reduce noise, complete silencing, and improve the exhaust time of the system. The air inlet cylinder 11 has a silent performance and one end is in a sealed state. When the gas enters the air inlet cylinder 11 at a high speed, it hits the sealed end of the air inlet cylinder 11 to complete the buffering, preventing the sound-absorbing cotton 12 from being subjected to severe impact and extending its service life. The isolation layer 3 is fixed by four connecting columns 4. The guide rod 6 passes through the air inlet cylinder 11. The clamp 7 adopts a PVC clamp 7. The number is preferably three, which respectively clamp the upper, middle and lower parts of the side of the air inlet cylinder 11. The air inlet cylinder 11 is installed in the groove of the cone 22 and the cone 22 is abutted. The air inlet cylinder 11, the connecting column 4 and the isolation layer 3 are perfectly accommodated in the cylinder space between the air outlet cylinder 21 and the cone 22.

[0029] The floating hole blocking device includes a floating ball 5 and a guide rod 6. The floating ball 5 can be detachably mounted on the guide rod 6. The guide rod 6 axially penetrates the air inlet inner tube 1, the air outlet outer tube 2 and the isolation layer 3. The floating ball 5 is located below the cone 22. The floating ball 5 is adapted to the opening of the cone 22. When the floating ball 5 is lifted by the water flow, it can be tightly combined with the cone 22 penetrated by the guide rod 6 to prevent water leakage and protect the exhaust valve. The guide rod 6 serves to limit the floating ball 5 and prevent it from running around. The guide rod 6 can slide up and down in the penetrated device. A disc is provided at the end of the guide rod 6 to prevent the floating ball 5 from excessively falling and provide a falling limit value for it. The floating ball 5 is threadedly connected to the guide rod 6, and the floating ball 5 is suspended in the exhaust pipe 04 through the guide rod 6.

[0030] Working principle: When the staff starts the liquid filling pump and opens the ball valve 02 to drain water, the air pressure in the pipe is greater than the external air pressure, and the gas enters the exhaust pipe 04 for exhaust before the water flow. The gas quickly enters the air intake tube 11 through the opening of the cone 22. The sealed end of the air intake tube 11 is for the gas to flow slowly. The square through hole on the air intake tube 11 guides the turning airflow, so that it passes through the sound-absorbing cotton 12 at a steady speed for silencing, and further passes through the isolation layer 3 to complete the exhaust. When the exhaust is completed, the external air pressure is greater than the internal air pressure for reflux. At this time, the impurity particles in the external gas are isolated by the isolation layer 3;

[0031] When water flows into the exhaust pipe 04, due to the existence of the floating ball 5, the water flow lifts up the floating ball 5, and the floating ball 5 finally closely contacts the opening of the second bottom surface of the cone 22 to prevent water leakage.

[0032] The above description is only a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes for application in other fields. However, any simple modification or equivalent change made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
