Description

Technical Field

[0001] This application relates to the field of gas-liquid linkage valve technology, specifically to a gas purification component and a power gas pipeline delivery system. Background Technology

[0002] In a pneumatic pipeline delivery system, valves are used to control the opening and closing of the pneumatic pipeline. To ensure the valve's response speed, the pneumatic gas supplied in the system can be used to drive the valve's opening and closing. Under this architecture, ensuring stable valve operation and extending equipment lifespan has been a major concern, and existing technologies often fail to address this issue. Utility Model Content

[0003] The purpose of this application is to provide a gas purification component and a power gas pipeline delivery system, which aims to solve the problem of how to ensure the stable operation of valves and extend the service life of equipment.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: In a first aspect, embodiments of this application provide a gas purification component applied between a power gas delivery pipeline and a gas storage device. The gas storage device supplies power gas to a gas-liquid linkage valve located on the power gas delivery pipeline to drive the gas-liquid linkage valve to switch between an open state and a closed state. The gas purification component includes a housing and a filter unit. Vent holes are provided at opposite ends of the housing. The vent hole at one end of the housing is connected to the power gas delivery pipeline, and the vent hole at the other end of the housing is connected to the gas storage device. Power gas from the power gas delivery pipeline can flow into the housing and flow out from the housing to the gas storage device. The filter unit is installed inside the housing and is used to filter out impurities in the power gas.

[0005] This embodiment incorporates a gas purification component between the power gas delivery pipeline and the gas storage device. The component's housing has vents at opposite ends, one end connecting to the power gas delivery pipeline and the other to the gas storage device, allowing power gas to flow in and out of the housing. Simultaneously, a filter unit installed inside the housing effectively removes impurities from the power gas. This design ensures that the power gas entering the gas storage device from the power gas delivery pipeline is purified. Because pure power gas supplies the pneumatic-hydraulic linkage valve, it avoids the adverse effects of impurities on the valve, such as wear and blockage, thereby ensuring stable switching between open and closed states, reducing the probability of malfunctions, and ultimately achieving the goal of ensuring stable valve operation and effectively extending equipment lifespan.

[0006] In one possible implementation of the first aspect, the filtration unit includes an adsorption structure for adsorbing water and sulfur from the motive gas.

[0007] This embodiment achieves effective adsorption of water and sulfur in the power gas by adding an adsorption structure to the filter unit. Water and sulfur are common impurities in natural gas, and their corrosive effect on equipment is particularly significant. The adsorption structure can specifically remove these harmful substances, further improving the purity of the power gas. When the power gas flows through the adsorption structure, the water and sulfur are effectively adsorbed, thereby avoiding their potential harm to downstream equipment and pipelines.

[0008] In one possible implementation of the first aspect, the adsorption structure includes a first adsorption structure and a second adsorption structure, wherein the first adsorption structure is used to adsorb water in the power gas and the second adsorption structure is used to adsorb sulfur in the power gas.

[0009] This embodiment achieves targeted adsorption treatment of water and sulfur in the power gas by refining the adsorption structure into a first adsorption structure and a second adsorption structure. Specifically, the first adsorption structure is dedicated to adsorbing water in the power gas, effectively preventing moisture from entering the gas-liquid linkage valve and its actuator, thus avoiding equipment corrosion and hydraulic oil emulsification problems caused by moisture. Simultaneously, in low-temperature environments such as winter, it can also prevent water from freezing and causing malfunctions of the solenoid valve, ensuring stable system operation. The second adsorption structure focuses on adsorbing sulfur in the power gas. Sulfur is also highly corrosive to equipment; through the treatment of the second adsorption structure, the damage caused by sulfur to the equipment can be significantly reduced, further extending the service life of the equipment and reducing the failure rate caused by corrosion. This refined adsorption structure design not only improves purification efficiency but also enhances the stability and reliability of the system.

[0010] In one possible implementation of the first aspect, the filter unit further includes a filter element structure for filtering out dust from the power air.

[0011] This embodiment enhances the purification effect by adding a filter element structure to the filter unit of the gas purification component, specifically filtering dust from the power gas. Specifically, the filter element structure, with its precise filtration performance, efficiently intercepts dust particles in the power gas, preventing them from entering the pneumatic-hydraulic linkage valve and its actuator. This not only avoids dust wear and blockage of the equipment but also ensures the purity of the power gas, providing strong support for the stable operation of the pneumatic-hydraulic linkage valve. Simultaneously, because dust is effectively filtered, equipment malfunctions and safety hazards caused by dust accumulation are reduced, further improving the safety and reliability of the entire power gas pipeline delivery system.

[0012] In one possible implementation of the first aspect, the filter element structure includes a first filter element structure and a second filter element structure, the first filter element structure and the second filter element structure are located on both sides of the adsorption structure, and the first filter element structure, the adsorption structure and the second filter element structure are arranged sequentially along the flow direction of the power gas in the housing.

[0013] This implementation configures the filter structure to include a first filter structure and a second filter structure, positioned on either side of the adsorption structure and arranged sequentially along the flow direction of the power gas within the housing. This layout allows the power gas to pass through the first filter structure, adsorption structure, and second filter structure sequentially during flow, achieving multiple filtration and purification of impurities in the power gas. The first and second filter structures can respectively intercept dust particles of different sizes, further improving the dust removal efficiency in the power gas. Simultaneously, the adsorption structure, located between the two, can effectively adsorb water and sulfur in the power gas, ensuring that these harmful components do not enter subsequent equipment, and also preventing dust from entering the adsorption structure and causing blockage to a certain extent. This structural design not only improves the purification effect of the gas purification component but also enhances its stability and reliability. Through multiple filtration and purification, the stable operation of the gas-liquid linkage valve and its actuator can be guaranteed in all aspects, reducing equipment failures, lowering maintenance costs, and thus improving the safety and reliability of the entire power gas pipeline delivery system.

[0014] In one possible implementation of the first aspect, the diameter of the vent is less than 50µm.

[0015] This embodiment further enhances the efficiency of the gas purification component by setting the diameter of the vent to less than 50µm. The small-diameter vent effectively blocks the passage of fine particles, ensuring that the purified power gas is purer and virtually free of impurities. This not only further reduces the risk of wear and failure due to impurities but also improves the operating efficiency and reliability of the entire power gas pipeline delivery system. Furthermore, the small-diameter vent design facilitates more precise control of the power gas flow rate, thereby meeting the specific needs of different application scenarios.

[0016] In one possible implementation of the first aspect, the housing includes a housing body and an end cap connected to the housing body; a vent at one end of the housing is located on the end cap, and a vent at the other end of the housing is located on the housing body; or, a vent at the other end of the housing is located on the end cap, and a vent at one end of the housing is located on the housing body.

[0017] This embodiment designs the housing as including a housing body and an end cap connected to the housing body, with vents located on the end cap and housing body respectively. This makes the gas purification component more flexible and convenient to install, and also facilitates the inspection and replacement of components such as the filter unit inside the housing. This effectively improves equipment maintenance efficiency, reduces equipment downtime caused by inconvenient maintenance, lowers maintenance costs, and ensures the stable operation of the gas-liquid linkage valve.

[0018] Specifically, when one end of the housing has a vent on the end cap and the other end has a vent on the housing body, this design facilitates disassembly and assembly, making it easier to connect and replace the gas purification components in the power gas pipeline. This design also facilitates regular inspection and cleaning of the filter unit inside the housing, ensuring it maintains high efficiency. When maintenance or replacement of the filter unit is required, simply opening the end cap allows for easy operation, significantly improving maintenance efficiency. When the other end of the housing has a vent on the end cap and the other end has a vent on the housing body, this design enhances the filtration effect of the power gas within the housing. After entering the housing, the power gas is relatively buffered by gravity, and large particles are initially intercepted here. Subsequently, the power gas continues to flow to the vicinity of the vent on one end of the end cap, where the filter unit performs a more refined filtration. Because the flow path of the power gas within the housing is rationally designed, it can make more thorough contact with the filter unit, thereby improving filtration efficiency and effectiveness. This design not only optimizes the filtration process of the power gas, but also further enhances the purification capacity of the gas purification components, providing a stronger guarantee for the stable operation of the gas-liquid linkage valve.

[0019] In one possible implementation of the first aspect, the gas purification assembly further includes a telescopic member located within the housing and on the side of the filter unit opposite to the end cap.

[0020] This embodiment enhances the functionality and adaptability of the gas purification assembly through an innovative design that incorporates a retractable component within the housing and positions it on the side of the filter unit opposite the end cap. Specifically, the retractable component adjusts its extension and retraction according to pressure changes in the motive gas within the housing, effectively buffering the impact of the motive gas and reducing its influence on the filter unit and the entire housing. This design not only improves the durability of the gas purification assembly but also extends its service life. In practical applications, the pressure and flow rate of the motive gas may change after entering the housing. Without a proper buffering mechanism, these changes may directly impact the filter unit, leading to decreased filtration efficiency or even damage. By introducing the retractable component, effective buffering and regulation of the motive gas can be achieved, allowing it to flow more smoothly through the filter unit, thus ensuring that the filtration effect remains at a high level. Furthermore, the retractable component facilitates the maintenance and replacement of the filter unit. When cleaning or replacing the filter unit, the retractable component provides sufficient operating space, allowing maintenance personnel to easily complete the relevant operations. This not only improves maintenance efficiency but also reduces the risk of equipment failure due to improper maintenance.

[0021] In one possible implementation of the first aspect, the shell body and the end cap are detachably connected.

[0022] This embodiment further enhances the flexibility and maintainability of the gas purification assembly by designing the housing and end caps to be detachably connected. Specifically, this detachable design makes the connection between the housing and end caps more convenient, allowing operators to disassemble and assemble the gas purification assembly as needed. When maintaining or replacing the filter unit, simply removing the end caps provides easy access to the components inside the housing, greatly simplifying the maintenance process and reducing operational difficulty. Simultaneously, the detachable design facilitates comprehensive cleaning and inspection of the gas purification assembly, ensuring it is always in good working order. Furthermore, when a component of the gas purification assembly malfunctions or is damaged, operators can quickly disassemble and replace the damaged component, thereby rapidly restoring normal equipment operation, reducing downtime caused by equipment failure, and improving the overall operating efficiency of the power gas pipeline delivery system.

[0023] In one possible implementation of the first aspect, the shell body and the end cap are connected by threads.

[0024] This embodiment uses a threaded connection to connect the shell body and the end cap, which is not only simple in structure and easy to operate, but also provides a tight connection that effectively prevents power gas leakage and ensures the sealing performance of the gas purification component. The threaded connection design makes installation and disassembly of the shell body and end cap more convenient; operators can connect or disconnect simply by rotating, without the need for additional complex tools or operations, greatly improving the efficiency and convenience of equipment maintenance. At the same time, the tightness of the threaded connection effectively resists the influence of pressure differences inside and outside the shell on the connection points, preventing safety hazards caused by gas leakage and further ensuring the safe and reliable operation of the entire power gas pipeline delivery system.

[0025] Secondly, embodiments of this application provide a power gas pipeline delivery system, which includes a power gas delivery pipeline, a gas storage device, and a gas purification component as described in any of the above technical solutions; the power gas delivery pipeline is used to deliver power gas, and the power gas delivery pipeline is equipped with a gas-liquid linkage valve; the gas storage device is used to supply power gas to the gas-liquid linkage valve to drive the gas-liquid linkage valve to switch between an open state and a closed state; the gas purification component is connected between the power gas delivery pipeline and the gas storage device for purifying the power gas.

[0026] This embodiment achieves effective purification of the power gas by connecting a gas purification component between the power gas delivery pipeline and the gas storage device. In the power gas pipeline delivery system, the power gas delivery pipeline is responsible for transporting the power gas, and a pneumatic-hydraulic linkage valve installed on it is used to control the gas flow. The gas storage device is responsible for supplying power gas to the pneumatic-hydraulic linkage valve to drive the valve to switch between open and closed states, thereby achieving precise control of gas flow. As the core component of this embodiment, the gas purification component purifies the power gas output from the gas storage device, removing harmful impurities such as dust, water, and sulfur, ensuring that the power gas entering the pneumatic-hydraulic linkage valve and its actuator is pure and free of impurities. This design not only avoids the corrosion and wear of equipment caused by impurities, reducing equipment failures, but also ensures the stability of hydraulic oil performance, extends its service life, and thus reduces equipment maintenance costs. At the same time, the purified power gas can drive the pneumatic-hydraulic linkage valve more stably and reliably, improving the safety and reliability of the entire power gas pipeline delivery system.

[0027] Since the power gas pipeline delivery system provided in this application includes the gas purification component described in any of the above technical solutions, both can solve the same technical problem and achieve the same technical effect, so they will not be described again.

[0031] In the embodiments of this application, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first," "second," and "third" may explicitly or implicitly include one or more of that feature.

[0032] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one" does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0033] In a first aspect, embodiments of this application provide a gas purification component 100, please refer to... Figure 1 , Figure 1 This is a cross-sectional structural schematic diagram of a gas purification assembly 100 provided in some embodiments of this application. The gas purification assembly 100 is applied between a power gas delivery pipeline and a gas storage device. The gas storage device supplies power gas to a gas-liquid linkage valve located on the power gas delivery pipeline to drive the gas-liquid linkage valve to switch between an open and closed state. The gas purification assembly 100 includes a housing 10 and a filter unit 20. Vent holes 1 are respectively provided at opposite ends of the housing 10. One vent hole 1 at one end of the housing 10 is connected to the power gas delivery pipeline, and the other vent hole 1 at the other end of the housing 10 is connected to the gas storage device. Power gas from the power gas delivery pipeline can flow into the housing 10 and flow out from the housing 10 to the gas storage device. The filter unit 20 is installed inside the housing 10 and is used to filter out impurities in the power gas.

[0034] In this embodiment, effective purification of the power gas is achieved by configuring a gas purification component 100 between the power gas delivery pipeline and the gas storage device and defining its structure. Specifically, a housing 10 with a vent 1 is used to connect the power gas delivery pipeline to the gas storage device, and a filter unit 20 is installed inside the housing 10. In the prior art, unpurified power gas often contains impurities such as dust, moisture, and sulfur. These impurities, after entering the gas storage device, can cause corrosion of the valve seals and jamming of the valve core during the actuation of the gas-liquid linkage valve, thereby affecting the stable operation of the valve and shortening the service life of the equipment. In this embodiment, the vent 1 design of the housing 10 ensures that the power gas can flow through the purification component in an orderly manner, and the filter unit 20 can specifically remove impurities in the power gas, making the power gas entering the gas storage device purer. Driven by pure power gas, the gas-liquid linkage valve can more stably complete the opening and closing switching, reducing the probability of failure. Compared with the prior art, this embodiment shows significant technical advantages in ensuring stable valve operation and extending the service life of the equipment.

[0035] Please see Figure 1 In some embodiments, the filter unit 20 may include an adsorption structure 21 for adsorbing water and sulfur in the motive gas.

[0036] In this embodiment, the composition of the filter unit 20 is defined as including an adsorption structure 21 for adsorbing moisture and sulfur compounds in the power gas. This is because moisture in the power gas condenses on the surface of pipes and valve components, causing corrosion of metal parts, while sulfur compounds react chemically with metals, causing chemical corrosion. These two types of substances are the main causes of malfunctions in the gas-liquid linkage valve and shortened equipment lifespan. Existing technologies lack specific treatment solutions for these two key corrosive components. Compared to the above embodiment where the filter unit 20 only proposes a "filtering out impurities" solution, this embodiment specifically defines the function of the adsorption structure 21 as adsorbing moisture and sulfur compounds, constructing a targeted purification mechanism for the core harmful components in the power gas. This more effectively reduces the risk of corrosion from moisture and sulfur compounds to the gas-liquid linkage valve and pipeline system, effectively improves the operational stability of the power gas pipeline delivery system, reduces maintenance needs due to corrosion, and extends the actual service life of the equipment to a certain extent. This effectively solves the technical problems mentioned in the background art regarding ensuring stable valve operation and equipment lifespan.

[0037] Please see Figure 1 In some embodiments, the adsorption structure 21 includes a first adsorption structure 211 and a second adsorption structure 212, wherein the first adsorption structure 211 is used to adsorb water in the power gas and the second adsorption structure 212 is used to adsorb sulfur in the power gas.

[0038] In this embodiment, the composition of the adsorption structure 21 is defined as including an independently configured first adsorption structure 211 and a second adsorption structure 212, which are used to adsorb moisture and sulfur compounds in the power gas, respectively. This is because moisture and sulfur compounds have different physicochemical properties and require adsorption materials with different characteristics for targeted treatment. Compared to the above embodiment where the adsorption structure 21 is not subdivided and moisture and sulfur compounds are treated by mixing a single structure, this embodiment divides the adsorption structure 21 into two independent parts, allowing the two impurities to be efficiently removed by suitable adsorption materials. This avoids the problem of decreased adsorption efficiency caused by insufficient material compatibility of a single structure, thereby more effectively reducing the content of the two key corrosive components in the power gas, further improving the corrosion resistance of the gas-liquid linkage valve and pipeline system, and extending the stable operation cycle of the equipment.

[0039] Of course, in some other embodiments, the adsorption structure 21 can also be a single-layer structure that can adsorb both water and sulfur. In this way, the structure of the adsorption structure 21 is simple and easy to assemble.

[0040] Please see Figure 1 In some embodiments, the filter unit 20 further includes a filter element structure 22 for filtering out dust from the power air.

[0041] In this embodiment, the composition of the filter unit 20 is defined to include a filter element structure 22 for filtering dust from the power gas. This is because dust and other impurities in the power gas can cause wear and jamming of internal components of the pneumatic-hydraulic linkage valve, affecting the valve's response accuracy and service life. The previous embodiments only addressed corrosive impurities such as water and sulfur, without addressing the filtration of dust and other impurities. Compared to the previous embodiments, this embodiment, by adding the filter element structure 22, enables the filter unit 20 to remove mechanical impurities such as dust. This complements the adsorption structure 21, jointly achieving composite purification of multiple impurities in the power gas. This more comprehensively reduces damage to the pneumatic-hydraulic linkage valve and pipeline system caused by impurities, further improving the operational stability and equipment reliability of the power gas pipeline delivery system.

[0042] Of course, in some other embodiments, the filter element structure 22 can also be made of precision multi-layer filter material, with each layer designed to filter dust particles of a specific size. The outermost layer typically uses coarse filter material to intercept larger dust particles and prevent them from entering the inner filter layers; the middle layer uses fine filter material to further filter out smaller dust particles; and the inner layer uses ultrafine filter material to perform final fine filtration of the power air, ensuring that the output power air is almost free of dust particles. This multi-layer filter element structure 22 design not only improves filtration efficiency but also ensures that the filtered power air quality is stable and reliable, meeting the stringent requirements of various power air pipeline delivery systems.

[0043] Please see Figure 1 In some embodiments, the filter element structure 22 includes a first filter element structure 221 and a second filter element structure 222. The first filter element structure 221 and the second filter element structure 222 are located on both sides of the adsorption structure 21, and the first filter element structure 221, the adsorption structure 21 and the second filter element structure 222 are arranged sequentially along the flow direction of the power gas in the housing 10.

[0044] In this embodiment, the composition of the filter element structure 22 is defined as including a first filter element structure 221 and a second filter element structure 222 located on both sides of the adsorption structure 21, arranged sequentially along the direction of gas flow. This is because impurities such as dust in the gas need to be removed more thoroughly through multi-stage filtration, and the adsorption structure 21 may generate debris during operation or need to avoid direct contact with large particles of impurities. Compared to the above embodiment where the filter element structure 22 is only set in a single configuration, this embodiment divides the filter element structure 22 into two stages and arranges them reasonably. The gas first passes through the first filter element structure 221 to remove larger particles of impurities, then passes through the adsorption structure 21 to remove corrosive components such as water and sulfur, and finally passes through the second filter element structure 222 to intercept fine dust and debris that may be generated by the adsorption structure 21. This forms a progressive purification process of "pre-filtration - adsorption purification - fine filtration", thereby removing dust more efficiently and protecting the adsorption structure 21, further improving the cleanliness of the gas, and reducing the mechanical wear and functional impact of impurities on the gas-liquid linkage valve and pipeline system.

[0045] Meanwhile, since the first filter element structure 221 and the second filter element structure 222 are located on both sides of the adsorption structure 21, no matter which end of the housing 10 the vent 1 enters from, the dust particles in the motive gas can be prevented from directly entering the adsorption structure 21, thereby preventing dust particles from clogging the adsorption structure 21 and extending its service life.

[0046] Please see Figure 1In some embodiments, the diameter of the vent 1 is less than 50µm. For example, the diameter of the vent 1 can be 5µm, 15µm, 20µm, 25µm, 30µm, 35µm, 40µm, 45µm, or 49µm, etc.

[0047] In this embodiment, the diameter of the vent hole 1 is limited to less than 50 μm because large particulate impurities (such as rust, welding slag, etc.) that may exist in the power gas delivery pipeline can cause severe wear to the precision components of the pneumatic-hydraulic linkage valve. The previous embodiment did not limit the size of the vent hole 1. This embodiment, by setting a small-diameter vent hole 1, utilizes its physical interception effect to screen large particulate impurities at the initial stage when the power gas enters the purification component. This prevents particles larger than 50 μm in diameter from entering the housing 10 through the vent hole 1, thereby reducing the burden on the subsequent filtration unit 20, lowering the risk of damage to the gas-hydraulic linkage valve seals and moving parts by impurities, extending the equipment's service life, and improving the operational reliability of the power gas pipeline delivery system.

[0048] Of course, in some other embodiments, the diameter of the vent 1 can be customized according to the specific needs of the power gas pipeline delivery system. For example, in applications requiring higher precision purification, the diameter of the vent 1 can be further reduced to intercept smaller impurity particles. Conversely, in applications with lower impurity content or less stringent purification requirements, the diameter of the vent 1 can be appropriately increased to reduce airflow resistance and improve the flow efficiency of the power gas. This flexible design allows the gas purification component 100 to better adapt to the needs of different power gas pipeline delivery systems, ensuring purification effectiveness and equipment operational stability.

[0049] Please see Figure 1 In some embodiments, the housing 10 includes a housing body 11 and an end cap 12 connected to the housing body 11; a vent 1 at one end of the housing 10 is provided on the end cap 12, and a vent 1 at the other end of the housing 10 is provided on the housing body 11; or, a vent 1 at the other end of the housing 10 is provided on the end cap 12, and a vent 1 at one end of the housing 10 is provided on the housing body 11.

[0050] In this embodiment, the structure of the housing 10 is defined as including a housing body 11 and an end cap 12, with vent holes 1 located on both. This design facilitates maintenance of the internal filter unit 20 by disassembling the end cap 12, and the distribution of the vent holes 1 guides the motive air axially through the filter unit 20 to ensure purification efficiency. Compared to the above embodiments that only mention the housing 10 having vent holes 1 without specifying the structure, this embodiment solves the problem of difficult replacement of the filter unit 20 through a detachable housing 10 structure. The reasonable layout of the vent holes 1 improves purification efficiency, thereby extending the service life of the equipment and reducing maintenance costs. In specific implementation, the filter unit 20 can be installed into the housing body 11 and then connected to the end cap 12. The motive air flows in from one end of the vent hole 1, passes through the filter unit 20, and flows out from the other end. Maintenance can be performed by disassembling the end cap 12. (See reference...) Figure 1 Vent 1 includes a first vent 4 and a second vent 5.

[0051] For example, when the motive gas flows into the housing 10 along the direction from the first vent 4 to the second vent 5 for purification, large particulate impurities are initially intercepted here. As the airflow continues deeper, after being purified layer by layer by the filter element structure 22 and the adsorption structure 21, it finally flows out from the vent 5 at the other end of the housing body 11 or end cap 12. At this point, the motive gas has become pure and dry, meeting the usage requirements of subsequent equipment such as the gas-liquid linkage valve. This design not only optimizes the flow path of the motive gas but also ensures the continuity and efficiency of the purification process. At the same time, the detachable connection between the housing body 11 and the end cap 12 also greatly facilitates the maintenance of the equipment and the replacement of the filter element structure 22. In practical applications, operators can easily disassemble the end cap 12 to inspect, clean, or replace the filter element structure 22 and the adsorption structure 21, thereby ensuring that the gas purification component 100 is always in optimal working condition, providing a solid guarantee for the long-term stable operation of the motive gas pipeline delivery system.

[0052] Optionally, when the power gas flows into the housing 10 for purification along the direction from the second vent 5 to the first vent 4, the power gas is relatively buffered within the housing 10 under the influence of gravity, and large particulate impurities are initially intercepted here, thereby further improving the filtration effect of the power gas within the housing 10. Subsequently, after dual purification by the filter element structure 22 and the adsorption structure 21, dust, moisture, and sulfur components in the power gas are effectively removed. When the purified power gas flows out from the vent 4 at the other end of the housing body 11 or end cap 12, its quality has reached a high standard and can be directly supplied to subsequent equipment such as the pneumatic-hydraulic linkage valve. This design not only significantly improves the purification efficiency of the power gas but also ensures that the quality of the purified power gas is stable and reliable, fully meeting the stringent requirements of the power gas pipeline delivery system.

[0053] Please see Figure 1In some embodiments, the gas purification assembly 100 further includes a retractable member 2, which is located inside the housing 10 and on the side of the filter unit 20 opposite to the end cap 12.

[0054] In this embodiment, the structure of the gas purification assembly 100 is defined by adding a retractable member 2. The retractable member 2 is located inside the housing 10 and on the side of the filter unit 20 facing away from the end cap 12. This is because the filter unit 20 may loosen under long-term use or airflow impact, resulting in a gap between it and the housing 10, allowing the motive gas to flow through the gap without sufficient purification. Compared to the above embodiment where the housing 10 is composed only of the housing body 11 and the end cap 12, this embodiment uses the elastic force of the retractable member 2 to continuously press the filter unit 20, ensuring close contact between the filter unit 20 and the housing 10 and preventing gaps. In specific implementation, the retractable member 2 is placed in the corresponding position inside the housing body 11, and then the filter unit 20 and the end cap 12 are installed sequentially. The retractable member 2, when compressed, generates a reverse thrust to fix the filter unit 20. This design improves the stability of motive gas purification, reduces impurity leakage caused by the loosening of the filter unit 20, further ensures the stable operation of the gas-liquid linkage valve, and extends the service life of the equipment.

[0055] Of course, in some other embodiments, the expandable component 2 can also be made of other elastic materials, such as rubber or silicone. These materials have different elasticity and recovery properties, and can be selected according to the needs of the actual power gas pipeline delivery system. For example, in situations requiring higher pressure resistance, harder rubber can be selected as the material for the expandable component 2; while in situations requiring higher elasticity, softer materials such as silicone can be selected. This flexible material selection allows the expandable component 2 to better adapt to different working conditions, ensuring that the gas purification assembly 100 can operate stably under various pressure fluctuations. In addition, expandable components 2 made of different materials also have different corrosion resistance and wear resistance properties. Users can select the most suitable material according to the composition of the power gas and the delivery environment, thereby extending the service life of the gas purification assembly 100 and reducing maintenance costs.

[0056] Please see Figure 1 In some embodiments, the shell body 11 and the end cap 12 are detachably connected.

[0057] In this embodiment, the connection method between the shell body 11 and the end cap 12 is specified, clearly indicating that they are detachably connected. This is because the filter unit 20 and the telescopic component 2 require maintenance or replacement after long-term use, and the detachable connection allows for opening the internal space without damaging the shell 10. Compared to the technical solutions in the above embodiments that do not specify the connection method between the shell body 11 and the end cap 12, this embodiment makes maintenance operations more convenient through a detachable design. In specific implementation, the two can be connected by means of threads 3, snaps, etc. When maintenance is required, the shell body 11 and the end cap 12 can be separated to replace the components. This design reduces maintenance time and costs, ensures that the filter unit 20 and the telescopic component 2 are always in good condition, further improves the operational stability of the power air pipeline delivery system, and extends the service life of the equipment.

[0058] Please see Figure 1 In some embodiments, the shell body 11 and the end cap 12 are connected by threads 3.

[0059] In this embodiment, the connection method between the shell body 11 and the end cap 12 is specified, specifically that they are connected by a thread 3. This is because the thread 3 connection combines detachability and good sealing performance, simplifying maintenance while ensuring the airtightness of the shell 10. Compared to the above embodiments that only mention a detachable connection between the shell body 11 and the end cap 12, this embodiment, through the specific method of thread 3 connection, retains the advantage of convenient disassembly while ensuring that the shell 10 is not easily loosened during the power gas delivery process, reducing the risk of air leakage. In specific implementation, external threads 3 and internal threads 3 are machined at the connection points of the shell body 11 and the end cap 12, respectively. Tightening the end cap 12 tightly fits the shell body 11 to form a sealed space. During maintenance, the two can be separated by rotating in the opposite direction. This design addresses the problems of insufficient sealing or complex maintenance in existing technologies, further improving the operational stability of the power gas pipeline delivery system and extending the service life of the equipment.

[0060] Of course, in other embodiments, the shell body 11 and the end cap 12 can also be detachably connected by means of snap-fit ​​connection, flange connection, etc. Each of these connection methods has its advantages, and users can choose according to their actual needs and installation environment. For example, in situations requiring frequent disassembly and replacement of internal components, snap-fit ​​connection is favored due to its ease of operation and quick disassembly; while in situations requiring extremely high sealing performance, flange connection is the preferred choice due to its stable structure and reliable sealing. This flexible and diverse connection design not only enhances the adaptability and practicality of the gas purification component 100 but also greatly facilitates the user's installation, maintenance, and use.

[0061] Secondly, embodiments of this application provide a power gas pipeline delivery system, which includes a power gas delivery pipeline, a gas storage device, and a gas purification component 100 as described in any of the above technical solutions; the power gas delivery pipeline is used to deliver power gas, and the power gas delivery pipeline is equipped with a gas-liquid linkage valve; the gas storage device is used to supply power gas to the gas-liquid linkage valve to drive the gas-liquid linkage valve to switch between an open state and a closed state; the gas purification component 100 is connected between the power gas delivery pipeline and the gas storage device and is used to purify the power gas.

[0062] Please see Figure 1 In the above embodiment, the power gas delivery pipeline serves as the transmission channel for the power gas and is equipped with a pneumatic-hydraulic linkage valve. Under the action of the system control signal, the pneumatic-hydraulic linkage valve can quickly open or close, thereby controlling the flow of power gas. The gas storage device is used to store purified power gas and to provide sufficient power gas in a timely manner when the pneumatic-hydraulic linkage valve needs to operate, so as to drive the pneumatic-hydraulic linkage valve to flexibly switch between open and closed states. The gas purification component 100 is connected between the power gas delivery pipeline and the gas storage device, becoming a key line of defense to ensure the stable operation of the system.

[0063] For example, in actual natural gas transportation scenarios, natural gas drawn from underground pipelines as motive gas often contains impurities such as water, sulfur, and dust. If these impurities directly enter the gas-hydraulic linkage valve, they will corrode the equipment, shorten the service life of the hydraulic oil, and even cause valve malfunction. When the motive gas flows through the gas purification component 100, the filter element structure 22 inside the component first intercepts dust, and the adsorption structure 21 further removes water and sulfur. After multi-stage purification, the pure motive gas enters the gas storage device. Subsequently, when the control CPU motherboard sends a signal, the motive gas in the gas storage device is delivered to the gas-hydraulic linkage valve, which pushes the gas-hydraulic linkage valve to complete the opening and closing action according to the command, ensuring the safe and stable operation of the natural gas transportation pipeline.

[0064] Since gas-liquid linkage valves are typically installed in critical locations such as RTU shut-off valve chambers along long-distance pipelines and inlet / outlet process pipelines at stations, they are required to respond quickly to switching actions and must not malfunction during operation. Otherwise, accidental closure will interrupt the process and cause an accident. The gas purification component 100 designed in this project can effectively filter hydrocarbon water and sulfur in the power gas, preventing equipment corrosion or oil emulsification caused by these substances. It also prevents solenoid valves from malfunctioning due to hydrocarbon water freezing, thereby preventing the main valve from being opened or closed accidentally.

[0065] In this embodiment, the gas purification component 100 can be replaced periodically according to the dew point content of the natural gas water, thereby effectively coping with changes in the composition of natural gas in different seasons or environments and ensuring that the purification effect always meets the standards. For example, in the high temperatures of summer, the evaporation of water in natural gas increases, and the filter element structure 22 and adsorption structure 21 of the purification component need to be replaced more frequently to prevent water saturation from affecting the purification efficiency. In the low temperatures of winter, attention needs to be paid to the problem of hydrocarbon water freezing, and timely insulation measures should be taken or the filter element and adsorption material adapted to the low-temperature environment should be replaced to ensure that the gas purification component 100 can operate stably under extreme weather conditions. This strategy of periodic replacement and maintenance not only improves the adaptability and durability of the gas purification component 100, but also further ensures the overall stability and safety of the power gas pipeline transportation system. At the same time, the gas purification component 100 is easy to operate and replace; it only needs to be installed at the power gas inlet of the gas-liquid linkage valve to achieve the purification of the power gas. In addition, the gas purification component 100 has many advantages, but since the power gas pipeline delivery system includes the gas purification component 100 as described in any of the above technical solutions, the two can solve the same technical problems and achieve the same technical effects, so they will not be described in detail here.

[0066] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
