Description

Technical Field

[0001] The present invention relates to the technical field of pipeline exhaust, and in particular to a pipeline exhaust device. Background Art

[0002] Water pipes are pipes used to transport water or other liquids and are widely used in various fields, such as water supply pipes in water supply systems in factories or communities, heating pipes in heating systems, etc.

[0003] In the process of injecting water or liquid into the pipeline, a large amount of gas will enter the pipeline along with the water or liquid. When the gas in the pipeline gradually increases, the pressure in the pipeline also gradually increases, which in turn creates resistance to the water flow in the pipeline and reduces the flow rate of the water. At the same time, the long-term presence of gas in the pipeline will also cause corrosion of the inner wall of the pipeline due to microbial growth, oxidation and other reasons. In addition, if there is too much gas in the pipeline, the water in the pipeline will generate a lot of noise during the flow. In order to reduce the gas in the pipeline, an exhaust valve is generally set at the end of the manifold in the pipeline, or an exhaust valve is built into the boiler in the heating system, but these exhaust valves can only remove a small amount of gas, and cannot remove a large amount of gas entering the pipeline.

[0039] The second gas precipitation member 7 enters from the second exhaust pipe 6 and passes through the three-way pipe 4 and the water outlet pipe 5 in sequence.

[0040] In this embodiment, the pipeline exhaust device 100 includes a water inlet pipeline, a first exhaust pipeline 1, and a first gas precipitation member 3, wherein the first exhaust pipeline 1 is connected to one side of the air inlet pipeline, and the first exhaust pipeline 1 is provided with an exhaust valve 2 on the side away from the air inlet pipeline. Then, when water fills the entire pipeline, excess gas will be discharged to the outside of the pipeline along the exhaust valve 2. It should be noted that the exhaust valve 2 is a prior art and this application will not go into details here.

[0041] At the same time, the pipeline exhaust device 100 also includes a three-way pipeline 4, a second exhaust pipeline 6 and a second gas precipitation member 7, wherein the three-way pipeline 4 has a first connecting port, a second connecting port and a third connecting port, that is, the first connecting port of the three-way pipeline 4 is connected to the first exhaust pipeline 1, the second connecting port of the three-way pipeline 4 is connected to the water outlet pipeline 5, and the third connecting port of the three-way pipeline 4 is connected to the second exhaust pipeline 6, that is, the three-way pipeline 4 plays a connecting role between the first exhaust pipeline 1, the second exhaust pipeline 6 and the water outlet pipeline 5 to ensure that water can smoothly flow into the water outlet pipeline 5 through the first exhaust pipeline 1 and the three-way pipeline 4, and the gas discharged from the water outlet pipeline 5 can be discharged to the outside of the pipeline through the exhaust valve 2. At the same time, the second gas precipitation member 7 enters the water outlet pipeline 5 from the second exhaust pipeline 6, so that the gas in the water outlet pipeline 5 can be pushed out of the gas outlet pipeline. Furthermore, by providing a first gas separation member 3 on the first exhaust pipe 1 and a second gas separation member 7 on the second exhaust pipe 6, the gas in the pipe can be better discharged, thereby increasing the flow rate of the water flow in the pipe and reducing the noise generated during the water flow.

[0042] In one embodiment, see Figure 2 and Figure 3 The first gas precipitation member 3 includes a tube body 31 and a nozzle block 32, the tube body 31 forms a flow cavity 311 with an inlet 312 and an outlet 313, the nozzle block 32 is installed on the outer peripheral wall of the tube body 31 and is connected to the flow cavity 311, the tube body 31 is arranged in the first exhaust pipe 1, the inlet 312 is connected to the water inlet pipe, the water flows into the flow cavity 311 through the inlet 312, and is discharged into the first exhaust pipe 1 through the outlet 313 and the nozzle block 32.

[0043] In this embodiment, the first gas precipitation member 3 includes a tube body 31 and a nozzle block 32, the tube body 31 forms a flow cavity 311 having an inlet 312 and an outlet 313, and the nozzle block 32 is installed on the outer peripheral wall of the tube body 31, and the nozzle block 32 is connected to the flow cavity 311. At the same time, the tube body 31 is arranged in the first exhaust pipe 1, and the inlet 312 of the tube body 31 is connected to the water inlet pipe, that is, the water flow can enter the flow cavity 311 through the inlet 312, and be discharged into the first exhaust pipe 1 through the outlet 313 of the tube body 31 and the nozzle block 32, and then, the flow velocity of the water is increased, so that the air in the water can be smoothly discharged to the outside through the exhaust valve 2, so that the gas in the pipeline can be better removed, thereby increasing the flow velocity of the water flow in the pipeline and reducing the noise generated during the water flow.

[0044] In one embodiment, see Figure 2 and Figure 3 The tube body 31 includes a first section 314 and a second section 315, the first section 314 is vertically connected to the second section 315, the inlet 312 is arranged on a side of the first section 314 away from the second section 315, the outlet 313 is arranged on a side of the second section 315 away from the first section 314, the nozzle block 32 is arranged in the first section 314, and the opening direction of the nozzle block 32 and the opening direction of the outlet 313 are both arranged in the direction of the exhaust valve 2.

[0045] In this embodiment, the tube body 31 includes a first section 314 and a second section 315, the first section 314 is vertically connected to the second section 315, the inlet 312 is arranged on the side of the first section 314 away from the second section 315, and the outlet 313 is arranged on the side of the second section 315 away from the first section 314, and the nozzle block 32 is arranged on the first section 314, and then the water from the water inlet sequentially passes through the outlet 313 and the nozzle block 32 into the first exhaust pipe 1, so that after increasing the water flow rate, the air in the water can be smoothly discharged from the exhaust valve 2. At the same time, the opening direction of the nozzle block 32 and the opening direction of the outlet 313 are both arranged in the direction of the exhaust valve 2 arranged in the first exhaust pipe 1, so that the gas in the first exhaust pipe 1 can be smoothly discharged from the exhaust valve 2 to the outside.

[0046] In one embodiment, see Figure 2 and Figure 3 There are multiple nozzle blocks 32, and along the length direction of the first section 314, the multiple nozzle blocks 32 are spaced apart on the outer wall of the first section 314. In this way, by setting up multiple nozzle blocks 32, while increasing the water flow, the water pressure can also be partially reduced to allow the air in the water to precipitate and be discharged along the exhaust valve 2 of the first exhaust pipe 1.

[0047] In one embodiment, see Figure 2 and Figure 3 The nozzle block 32 is gradually reduced in size on a side close to the first section 314 and away from the first section 314 . This arrangement can ensure that the speed at which water flows out of the nozzle block 32 can be increased.

It should be noted that the second exhaust pipe 6, the three-way pipe 4 and the water outlet pipe 5 are all circular pipes.

[0049] In one embodiment, see Figure 2 The diameter of the second gas precipitation member 7 is slightly larger than the inner diameter of the water outlet pipe 5, so that the water in the water outlet pipe 5 can be squeezed out.

It should be noted that the inlet valve 8 and the outlet valve 9 are both existing technologies, and this application will not be repeated in detail here.

[0052] In one embodiment, see Figure 1The pipeline exhaust device 100 also includes two opening and closing valves 10, one of which is arranged between the first exhaust pipeline 1 and the three-way pipeline 4 to close or connect the first exhaust pipeline 1 and the three-way pipeline 4, and the other opening and closing valve 10 is arranged on the second exhaust pipeline 6 close to the exhaust valve 2. When the second gas precipitation member 7 is placed in the water outlet pipeline 5, one of the opening and closing valves 10 and the water outlet valve 9 need to be closed, and the opening and closing valve 10 on the second exhaust pipeline 6 needs to be opened to ensure that there is no water flow in the water outlet pipeline 5 at this time, so that the second gas precipitation member 7 can be placed in the water outlet pipeline 5. Subsequently, one of the opening and closing valves 10, the water inlet valve 8 and the water outlet valve 9 are opened, and the opening and closing valve 10 on the second exhaust pipeline 6 is closed to fill the water outlet pipeline 5 with water, so that the excess gas can be discharged from the outside of the pipeline along the exhaust valve 2. It should be noted that the opening and closing valve 10 is a prior art, and this application will not be described in detail here.
