Description

Technical Field

[0001] This utility model relates to the field of gas pipe technology, specifically to a gas pipe odorization device. Background Technology

[0002] Gas, as a clean and efficient energy source, is used in residential life, industrial production, and commercial services. Because gas is colorless and odorless, leaks are difficult to detect and can cause safety accidents. Therefore, it is necessary to add odorant liquid with a special odor to the gas through an odorizing device so that users can detect leaks in time.

[0003] Traditional gas pipeline odorization devices consist of a storage tank, a delivery pipeline, a metering pump, and a control valve. During use, the metering pump delivers the odorizing liquid from the storage tank to the gas pipeline at a set flow rate through the control valve, where it mixes with the gas. However, the continuous operation of the metering pump can lead to unstable odorizing liquid addition, making it impossible to adjust in real time according to changes in gas flow rate, resulting in either over- or under-odorization.

[0004] To address the problems of traditional odorizing devices, existing technologies have been improved by combining flow sensors with intelligent control systems to adjust the amount of odorant added in real time based on the gas flow rate. However, in actual use, due to the unreasonable design of the odorant injection structure, the odorant is only injected from a fixed position in the pipeline, making it difficult to diffuse to the entire pipeline cross-section. This results in uneven distribution of the odorant within the gas pipeline and difficulty in fully mixing with the gas. Therefore, a gas pipeline odorizing device is proposed to solve the above problems. Utility Model Content

[0042] See attached document Figure 1 Appendix Figure 2 and attached Figure 4 An embodiment of this utility model provides a gas pipe odorization device, including a detection pipe 1 and a storage tank 2. The detection pipe 1 is provided with a mixing mechanism 3, which is used to increase the contact area between the odor liquid and natural gas. The top of the detection pipe 1 is fixedly connected to a storage tank 4. The top of the storage tank 4 is connected to a filling pipe 5. The filling pipe 5 is provided with a filtering mechanism 10, which is used to filter impurities and crystals in the odor liquid. The top of the filling pipe 5 is threadedly connected to a pipe cap 6. The bottom of the pipe cap 6 is provided with a self-sealing mechanism 7, which is used to prevent the odor liquid from leaking. The top of the storage tank 2 is connected to a conduit 8. The left side of the conduit 8 is provided with a filling mechanism 9, which is used to add odor liquid into the storage tank 4. The inner wall of the pipe cap 6 is fixedly connected with multiple sealing rings 11.

[0043] The mixing mechanism 3 includes an inner ring 301, the outer wall of which is fixedly connected to the inner wall of the detection tube 1. This provides a stable spatial carrier for the subsequent mixing of the odorous liquid and the fuel gas, ensuring the mixing process takes place within a fixed area. A notch 302 is provided at the top of the inner ring 301 to receive the odorous liquid flowing out of the outlet pipe 3061 and to provide conditions for establishing and breaking the pressure balance, thereby controlling the outflow rhythm of the odorous liquid. An annular groove 303 is provided on the outer wall of the inner ring 301 to guide the odorous liquid to flow around the inner wall of the detection tube 1, ensuring sufficient contact with the fuel gas. Multiple diverging grooves 304 are provided on the inner wall of the inner ring 301 to further disperse the odorous liquid and increase the contact area between the odorous liquid and the fuel gas. To improve the mixing effect, multiple anti-overflow protrusions 305 are fixedly connected to the inner wall of the inner ring 301 to prevent the odorous liquid in the dispersion tank 304 from overflowing due to excessive amount, ensuring that the odorous liquid flows within the set path and range. The top of the inner ring 301 is provided with a liquid outlet assembly 306, which is used to transport the odorous liquid in the storage tank 4 into the inner ring 301. The liquid outlet assembly 306 includes a liquid outlet pipe 3061, the bottom of which is fixedly connected to the bottom of the recess 302, and the top is connected to the bottom of the storage tank 4. It is the channel for the odorous liquid to flow from the storage tank 4 to the inner ring 301. Multiple pipe grooves 3062 are opened at the bottom of the liquid outlet pipe 3061, which cooperate with the recess 302 to form a pressure balance structure to control the outflow and stop of the odorous liquid.

[0044] Specifically, the foul liquid in the storage tank 2 is added to the storage tank 4 through the liquid adding mechanism 9. The liquid outlet pipe 3061 at the bottom of the storage tank 4 is fixed in the notch 302 on the inner ring 301. At this time, the foul liquid in the storage tank 4 tends to flow downwards due to gravity, flowing out from the liquid outlet pipe 3061 into the notch 302 and reaching the same height as the pipe groove 3062. However, for a short period of time, the external atmospheric pressure will support the liquid surface upwards, forming a balanced state, and the foul liquid will not flow out. When the foul liquid in the annular groove 303 slowly passes through the diffusion groove 304 and fills the inner ring 301, As the liquid level drops, an air gap appears between the notch 302 and the groove 3062, allowing outside air to enter the storage tank 4, disrupting the original pressure balance. The pressure inside the storage tank 4 increases, and the foul liquid flows out under gravity until the liquid level in the notch 302 covers the groove 3062 again. At this point, air stops entering, pressure balance is restored, and the water flow stops. The foul liquid, guided by the annular groove 303 and the diverging groove 304, surrounds the inner wall of the detection tube 1 and comes into full contact with the gas. The anti-overflow protrusion 305 prevents the foul liquid in the diverging groove 304 from overflowing.

[0045] See attached document Figure 1 Appendix Figure 2 and attached Figure 3The self-sealing mechanism 7 includes a leak plate 701. The outer wall of the leak plate 701 is slidably connected to the inner wall of the liquid addition pipe 5, providing guidance and support for the sliding of the leak plate 701 within the liquid addition pipe 5, ensuring its stability of movement. Multiple leakage ports 702 are provided on the top of the leak plate 701 to allow the odorous liquid to pass through and flow into the storage tank 4, realizing the function of adding the odorous liquid. A sealing block 703 is fixedly connected to the top of the leak plate 701 to seal the inner wall of the pipe cap 6 when no odorous liquid is added, preventing the odorous liquid from evaporating or leaking. The outer wall of the leak plate 701... Multiple springs 704 are fixedly connected to both the upper and lower sides. The elastic deformation and reset of the springs 704 provide power for the up-and-down movement of the leak plate 701, enabling the automatic opening and closing of the self-sealing mechanism 7. A force-bearing ring 705 is slidably connected to the inner wall of the liquid filling pipe 5 to bear the pressure when the leak plate 701 moves downwards, and cooperates with the filter cartridge 1002 to limit the downward movement of the leak plate 701. The top ends of the multiple springs 704 at the top are fixedly connected to the top of the inner wall of the pipe cover 6, and the bottom ends of the multiple springs 704 at the bottom are fixedly connected to the force-bearing ring 705. The top of ring 705 forms a complete elastic connection structure with spring 704, ensuring the normal operation of the self-sealing mechanism 7. The filtration mechanism 10 includes a positioning ring 1001, the outer wall of which is fixedly connected to the inner wall of the liquid addition pipe 5, for providing positioning and support for the filter cartridge 1002, ensuring the fixed position of the filter cartridge 1002 within the liquid addition pipe 5. The filter cartridge 1002 is slidably connected to the inner wall of the liquid addition pipe 5 for filtering impurities and crystals in the odorous liquid, preventing them from entering the liquid storage tank 4 and affecting the normal operation of the odorization device. The bottom of the filter cartridge 1002... The top of the filter cartridge 1002 is slidably connected to the positioning ring 1001, and cooperates with the positioning ring 1001 to achieve stable installation and positioning of the filter cartridge 1002. The bottom of the force ring 705 is slidably connected to the top of the filter cartridge 1002. When the filter plate 701 moves down, it restricts the downward movement of the filter plate 701 by contacting the filter cartridge 1002, and at the same time transmits pressure to the filter cartridge 1002. The inner wall of the filter cartridge 1002 is fixedly connected to the lifting rod 1003, which makes it easy for the operator to take out the filter cartridge 1002 for cleaning or replacement, thus improving the convenience of equipment maintenance.

[0046] Specifically, during liquid addition, the insert rod 9051 is inserted into the inner wall of the tube cap 6, and its bottom end presses against the sealing block 703, causing it to detach from the inner wall of the tube cap 6. The leak plate 701 moves downward inside the liquid addition tube 5, and the force ring 705 is blocked and stationary by the filter cartridge 1002. The springs 704 on both the upper and lower sides of the leak plate 701 deform, with the upper spring 704 being stretched and the lower spring 704 being compressed. When the foul liquid is squeezed out from the rod groove 9052, the foul liquid passes through the leak port. 702 flows into the storage tank 4. After the addition is completed, the insertion rod 9051 is pulled out. Under the strong elastic release of the spring 704, the sealing block 703 moves up and squeezes into the inner wall of the tube cap 6, returning to the initial position. The filter cartridge 1002 filters impurities and crystals in the odorous liquid. When it is necessary to clean the impurities in the filter cartridge 1002, unscrew the tube cap 6 from the liquid addition pipe 5, pull out the self-sealing mechanism 7, and use the lifting rod 1003 to take out the filter cartridge 1002.

[0047] See attached document Figure 1 Appendix Figure 2 and attached Figure 5 The liquid addition mechanism 9 includes a bidirectional tube 901, the right side of which is connected to the left side of the conduit 8 to establish a connection between the storage tank 2 and the subsequent liquid addition channel, enabling the smooth transfer of the odorous liquid. A piston 902 is slidably connected to the inner wall of the bidirectional tube 901. By sliding the piston 902 within the bidirectional tube 901, the odorous liquid is pushed and drawn in, controlling the delivery volume. A push rod 903 is fixedly connected to the top of the piston 902, allowing the operator to manually push the piston 902 to provide power for the delivery of the odorous liquid. A limiting component 904 is installed inside the bidirectional tube 901 to control the flow direction and flow rate of the odorous liquid, ensuring the stability and accuracy of the liquid addition process. An insertion component 905 is installed at the bottom of the liquid addition mechanism 9 to connect the liquid addition mechanism 9 to the tube cap 6. The system provides a channel for the outflow of odorous liquid. The limiting component 904 includes two one-way valves 9041. The outer walls of the two one-way valves 9041 are fixedly connected to the inner wall of the bidirectional pipe 901. Through the one-way conduction characteristic, it ensures that the odorous liquid can only flow in the set direction to prevent backflow. The inner wall of the bidirectional pipe 901 is fixedly connected to a limit block 9042 to limit the sliding range of the piston 902 and prevent the piston 902 from moving excessively and damaging the liquid adding mechanism 9. The insertion component 905 includes a rod 9051, the top of which is connected to the bottom of the bidirectional pipe 901 for insertion into the inner wall of the pipe cap 6 to trigger the opening of the self-sealing mechanism 7 and serve as a channel for the outflow of odorous liquid. The bottom of the bidirectional pipe 901 is provided with multiple rod grooves 9052 to facilitate the outflow of odorous liquid from the bidirectional pipe 901 to the liquid storage tank 4, ensuring the smoothness of liquid adding.

[0048] Specifically, the bidirectional pipe 901 serves as the core channel. Through the cooperation of piston 902 and push rod 903, the suction and push of the odorous liquid are manually controlled to meet different liquid addition requirements. The limit block 9042 ensures that the piston 902 moves within a safe range to avoid equipment damage. The one-way valve 9041 in the limiting component 904 uses its one-way conduction characteristic to prevent the odorous liquid from flowing back, ensuring the uniqueness of the flow direction and improving the stability and reliability of the liquid addition process. The insertion rod 9051 of the insertion component 905 is inserted into the pipe cap 6 to trigger the opening of the self-sealing mechanism 7. At the same time, the odorous liquid is smoothly introduced into the storage tank 4 through the rod groove 9052, realizing the rapid connection and sealing of the liquid addition channel.

[0049] Working principle: First, the odorous liquid in the storage tank 2 is added to the storage tank 4 through the liquid adding mechanism 9. During the addition, the odorous liquid enters the storage tank 4 through the conduit 8 and the liquid adding pipe 5. During this process, the filter mechanism 10 inside the liquid adding pipe 5 filters the odorous liquid, intercepting any impurities that may be present, preventing impurities from entering the storage tank 4, ensuring the purity of the odorous liquid, and preventing blockage of subsequent components. At the same time, multiple sealing rings 11 on the inner wall of the pipe cap 6 fit tightly with the liquid adding pipe 5, providing a good seal and preventing leakage of the odorous liquid during the addition process. When the storage tank 4 is full of odorous liquid, the pipe cap 6 is threaded onto the top of the liquid adding pipe 5. At this time, the pipe cap... The self-sealing mechanism 7 at the bottom of the storage tank 4 further ensures the airtightness of the liquid storage tank 4, preventing the odorous liquid from evaporating or leaking. The outlet pipe 3061 at the bottom of the storage tank 4 is fixed in the recess 302 on the inner ring 301. In the initial state, the odorous liquid in the storage tank 4 tends to flow downwards due to gravity. The odorous liquid flows out from the outlet pipe 3061 until the liquid level in the recess 302 is level with the height of the groove 3062 at the bottom of the outlet pipe 3061. At this time, the external atmospheric pressure supports the liquid level upwards, forming a balance with the gravity of the odorous liquid, so that the odorous liquid will not continue to flow out temporarily. During the gas transmission process, after the gas enters the detection pipe 1... As the gas flows along the inside of the detection tube 1, the annular groove 303 on the outer wall of the inner ring 301 gradually fills with the odorous liquid. The odorous liquid slowly passes through the dispersion groove 304 and fills the inner ring 301. During this process, guided by the dispersion groove 304, the odorous liquid distributes around the inner wall of the detection tube 1, thus making full contact with the gas. Due to the flow and distribution of the odorous liquid, the liquid level at the notch 302 and the groove 3062 drops, creating an air gap. At this time, outside air enters the storage tank 4 through this gap, breaking the original pressure balance. The pressure inside the storage tank 4 increases. Under the combined action of the increased pressure and gravity... The odorous liquid in the storage tank 4 flows out again until the liquid level in the recess 302 covers the pipe groove 3062 again. Air stops entering, and pressure balance is formed again. The outflow of odorous liquid also stops. This cycle is repeated to achieve intermittent addition of odorous liquid, ensuring that the odorous liquid is continuously and stably mixed with the gas. During this process, multiple anti-overflow protrusions 305 fixedly connected to the inner wall of the inner ring 301 play an important role. The anti-overflow protrusions 305 can prevent the odorous liquid in the diffusion groove 304 from overflowing due to excess, ensuring that the odorous liquid flows and distributes within the set path and range, ensuring that the odorous liquid is evenly and fully mixed with the gas, thereby achieving a good odorization effect.

[0050] Furthermore, when it is necessary to add odorous liquid to the storage tank 4, the insertion rod 9051 of the liquid adding mechanism 9 is inserted into the inner wall of the tube cap 6. The bottom end of the insertion rod 9051 presses against the sealing block 703, causing the sealing block 703 to detach from the inner wall of the tube cap 6. At the same time, it drives the leak plate 701 to move downward in the liquid adding tube 5. At this time, the springs 704 on both the upper and lower sides of the leak plate 701 are deformed: the top spring 704 is stretched and the bottom spring 704 is compressed. Since the bottom of the force ring 705 is slidably connected to the top of the filter cartridge 1002, and the bottom of the filter cartridge 1002 slides... Connected to the top of the positioning ring 1001, which is fixed to the inner wall of the liquid adding pipe 5, the force ring 705 is blocked by the filter cartridge 1002 and cannot move down. When the insertion rod 9051 is fully inserted, the foul liquid is squeezed out from the rod groove 9052 of the insertion rod 9051 and flows into the liquid storage tank 4 through the multiple leakage ports 702 at the top of the leakage plate 701. During this process, the filter cartridge 1002 of the filtration mechanism 10 filters the foul liquid, intercepting impurities and crystals to prevent them from entering the liquid storage tank 4, thereby avoiding clogging of the components of the mixing mechanism 3. After adding the odorant, pull the insert rod 9051 out of the tube cover 6. At this time, the elastic force of the spring 704 is released, the stretched top spring 704 contracts, and the compressed bottom spring 704 rebounds. Together, they cause the filter plate 701 to move upward, driving the sealing block 703 to move upward and squeeze into the inner wall of the tube cover 6, restoring the initial sealing state and preventing the odorant from evaporating or leaking. As the equipment is used, impurities and crystals will gradually accumulate inside the filter cartridge 1002, affecting the filtration effect. At this time, the filter cartridge 1002 needs to be cleaned. During cleaning... First, unscrew the cap 6 from the liquid filling tube 5. Then, pull out the self-sealing mechanism 7. Next, use the lifting rod 1003 fixed to the inner wall of the filter cartridge 1002 to remove the filter cartridge 1002 from the liquid filling tube 5 for cleaning or replacement. After cleaning, put the filter cartridge 1002 back into the liquid filling tube 5, so that its bottom is in contact with the top of the positioning ring 1001. Then, tighten the cap 6 onto the liquid filling tube 5. The leak plate 701 and the sealing block 703 of the self-sealing mechanism 7 return to their initial positions under the action of the spring 704, and the entire device returns to a state where it can work normally.
