Description

Technical Field

[0001] This utility model relates to the field of pipeline valve group insulation technology, specifically to an outdoor pipeline valve group insulation sleeve. Background Technology

[0002] In northern my country, winter temperatures are low, requiring outdoor pipeline systems to undergo insulation or heating measures to ensure normal operation. Valve assemblies, as key components of these systems, such as check valves, ball valves, and butterfly valves, directly impact the overall system's operational stability through their insulation performance. However, valve assemblies are generally characterized by irregular structures and limited installation space. Traditional methods of directly wrapping them with insulation material are not only difficult to implement but also struggle to achieve a complete and tight seal. This results in ineffective insulation, making the valve assemblies susceptible to severe temperature loss when exposed to cold air, and even freezing in winter. Furthermore, the need for regular maintenance, upkeep, or replacement of valve assemblies is compounded by the cumbersome disassembly of traditional wrapping methods, significantly increasing the difficulty and workload of maintenance.

[0003] To address the aforementioned maintenance inconvenience, patent CN220337853U employs a detachable valve assembly insulation sleeve. This detachable connection between the cover plate and the housing improves maintenance convenience to some extent. However, existing detachable insulation sleeves have significant drawbacks: their pipe openings are mostly fixed structures, with tightness adjustment achieved only through a single tightening strap. This limits their adaptability to pipes of different diameters, making it difficult to flexibly adjust according to the actual pipe dimensions. Furthermore, uneven stress during tightening can lead to uneven contact between the pipe opening and the pipe surface, resulting in localized gaps and affecting the overall insulation and sealing effect. Consequently, they fail to meet the insulation requirements of diverse pipe valve assemblies. Summary of the Invention

[0004] The technical problem to be solved by this utility model is how to improve the adaptability of the reserved pipe opening to pipes of different diameters.

[0005] The technical solution adopted by this utility model is: an outdoor pipeline valve group insulation sleeve, including a box body and a box cover installed on the top opening of the box body. The side wall of the box body is provided with a pipe opening for the pipe to pass through. The side wall of the box body is provided with a connecting seam. The inner wall of the pipe opening is provided with a sliding groove arranged along its axial direction. A split adapter assembly is installed in the pipe opening. The split adapter assembly includes at least two levels of split adapter units with different apertures. Each level of the split adapter unit includes a main adapter and a secondary adapter that can be mated. The outer periphery of the main adapter and the secondary adapter is provided with a slider that cooperates with the sliding groove.

[0006] The above structure has the following beneficial effects: By setting axial grooves on the inner wall of the pipe opening of the outdoor pipeline valve assembly insulation sleeve and setting an adapter assembly containing at least two levels of split-type adapter units with different orifice diameters, the sliders and grooves on the outer periphery of the main adapter and auxiliary adapter precisely match, achieving flexible adaptation to pipes of different diameters. The split-type structure facilitates disassembly and assembly at the valve assembly with the installed pipeline, allowing for the assembly and maintenance of the insulation sleeve without disassembling the pipeline. The multi-level orifice adapter units can be selected according to the actual pipe diameter combination, greatly improving the versatility of the insulation sleeve and avoiding the cost waste of customizing insulation sleeves for a single pipe diameter. At the same time, the cooperation between the sliders and grooves ensures the stability of the adapter unit after installation, reducing displacement caused by vibration and other factors during use, ensuring the fit between the pipeline and the insulation sleeve, thereby improving the thermal insulation effect and effectively reducing energy loss or equipment damage to the pipeline valve assembly caused by changes in outdoor temperature.

[0007] Preferably, the connecting seam is located above the pipe opening, and the two parts of the box body separated by the connecting seam are connected by adhesive fasteners.

[0008] A connecting seam is installed above the pipe opening on the side wall of the enclosure, and the two parts of the enclosure are connected by adhesive fasteners, significantly optimizing the ease of installation of the insulation sleeve. During installation, the enclosure can be disassembled along the connecting seam, the valve assembly can be wrapped around the pipe from above, and then quickly spliced ​​and fixed using adhesive fasteners. This eliminates the need to relocate or disassemble the already laid pipes, effectively adapting to complex on-site installation environments. The adhesive fastener connection method is simple to operate and reliable, ensuring the airtightness of the enclosure after splicing, preventing cold air from seeping in and affecting the insulation effect, and facilitating quick disassembly of the enclosure for subsequent valve assembly maintenance, reducing maintenance costs. Furthermore, the design of the connecting seam above the pipe avoids structural interference at pipe penetration points, ensuring a tight fit between the enclosure and the pipe, further enhancing the overall protective performance of the insulation sleeve.

[0009] Preferably, the box body and the box lid are also connected by another adhesive fastener.

[0010] The housing and cover are connected by another adhesive fastener, continuing the advantage of easy disassembly and assembly of the adhesive fastener, making the opening and closing of the cover simple and efficient. When routine inspection, maintenance or replacement of parts of the valve assembly is required, it is not necessary to disassemble the entire insulation sleeve. The cover can be opened simply by unfastening the adhesive fastener, which greatly shortens the inspection time and reduces the maintenance workload. At the same time, the connection method of the adhesive fastener can ensure a tight seal between the cover and the housing, effectively preventing cold air, rain or dust from the outdoor environment from entering the interior of the insulation sleeve. This maintains the heat insulation effect of the insulation sleeve and avoids the corrosion of impurities on the valve assembly components, thus extending the service life of the valve assembly.

[0011] Preferably, the slider is provided with an adjustment mechanism, which includes an adjustment cavity and an elastic adjustment plate disposed on the corresponding sliders of the primary and secondary adapters at each level. The elastic adjustment plate can be moved in the direction of the primary or secondary adapter.

[0012] An adjustment mechanism comprising an adjustment cavity and an elastic adjustment plate is provided on the slider. The elastic adjustment plate can be moved towards the main or auxiliary matching pair, facilitating the installation and disassembly of the main or auxiliary matching pair. The elastic adjustment plate can compensate for gaps through its own elasticity, improving the sealing performance and heat preservation effect of the mating, and adapting to complex working conditions such as vibration and temperature deformation. The tossing operation is more gentle and convenient, and can reduce rigid wear of components, extend service life, and take into account both practicality and economy.

[0013] Preferably, each of the main and auxiliary fittings except the last one has a limiting groove on its inner wall, and a limiting boss is provided on the side of the elastic adjustment plate away from the main or auxiliary fitting, the limiting boss cooperating with the limiting groove.

[0014] Except for the last level, each of the main and auxiliary adapters has a limiting groove on its inner wall, and the side of the elastic adjustment plate away from the adapter has a matching limiting boss, forming a reliable limiting and fixing structure. When the elastic adjustment plate is adjusted to the appropriate position, the limiting boss engages with the limiting groove, effectively locking the position of the elastic adjustment plate and preventing it from shifting due to vibration, temperature changes, or other factors during use. This ensures that the mating gap of the adapter units remains stable and avoids a decrease in insulation performance. Preferably, a toggle groove is provided on the end face of the elastic adjustment plate.

[0015] A sliding groove is provided on the end face of the elastic adjustment plate, providing a convenient force application point for its operation and effectively solving the problems of small size and inconvenience in direct manipulation. During installation or adjustment, operators can easily move the elastic adjustment plate by inserting their fingers or small tools into the sliding groove, reducing operational difficulty and making it particularly suitable for operation in confined spaces such as inside pipe openings. Preferably, the cross-section of the limiting boss is trapezoidal.

[0016] The limiting boss features a trapezoidal cross-section, offering the dual advantages of guidance and reliable locking. The beveled surface of the trapezoidal structure provides excellent guidance, allowing the limiting boss to smoothly embed into the limiting groove during the movement of the elastic adjustment plate, reducing jamming during installation and improving assembly efficiency. Simultaneously, the asymmetrical trapezoidal structure ensures that the beveled surface of the limiting boss fits snugly against the inner wall of the limiting groove after embedding, enhancing the stability of the limiting mechanism and effectively preventing reverse displacement of the elastic adjustment plate, further improving the locking effect of the adjustment mechanism.

[0017] Preferably, sealing rings are provided at the joints between the split-type adapter unit and the pipe opening, as well as at the joints between adjacent split-type adapter units.

[0018] Sealing rings are installed at the joints between the split-type matching units and the pipe openings, as well as at the joints of adjacent matching units, effectively filling the gaps between the components and forming multiple layers of sealing protection. The sealing rings prevent cold air from seeping into the insulation jacket through the joints, and also reduce heat loss from the pipe valve assembly, significantly improving the insulation effect of the insulation jacket and further reducing energy consumption. In addition, the sealing rings also prevent rainwater, dust, corrosive gases, and other impurities from entering the insulation jacket, avoiding problems such as corrosion and blockage at the valve assembly and pipe interfaces, extending the service life of the pipe valve assembly, and reducing maintenance frequency and costs.

[0027] Example The following description, in conjunction with specific embodiments, provides further details. Figure 1-4 As shown, this embodiment is an outdoor pipe valve assembly insulation sleeve, including a box body 10 and a box cover 20 covering the top opening of the box body 10. In this embodiment, the box body 10 and the box cover 20 are made of rubber and plastic insulation cotton. The side wall of the box body 10 has a pipe opening 11 for pipes to pass through. A connecting seam is also provided on the side wall of the box body 10. The connecting seam is located above the pipe opening 11, and the two parts of the box body 10 separated by the connecting seam are detachably connected by adhesive fasteners 12. The box body 10 and the box cover 20 are also detachably connected by another adhesive fastener 12. A flue gas axial extension groove is provided on the inner wall of the pipe opening 11. A split adapter assembly is installed in the pipe opening 11. The adapter assembly includes at least two levels of split adapter units with different apertures. In this embodiment, a three-level adapter is adopted. Each split adapter unit 13 includes a main adapter 131 and a secondary adapter 132 that can be mated. The outer periphery of the main adapter 131 and the secondary adapter 132 is provided with a slider 133 that cooperates with the groove. By the cooperation of the slider 133 with the groove, the split adapter unit can be prevented from rotating, and each level of split adapter unit 13 can be stably assembled in the pipe opening 11.

[0028] An adjustment mechanism is also provided on the slider 133. The adjustment structure includes an adjustment cavity 1331 on the corresponding slider 133 with primary and secondary adapters 131 and secondary adapters 132 at each level, and an elastic adjustment plate 1332 provided in the adjustment cavity 1331, which can be moved in the direction of the primary adapter 131 or the secondary adapter 132. In addition, a limiting groove is provided on the inner wall of each primary adapter 131 and secondary adapter 132 except for the last level. A limiting boss 1333 is provided on one side of the elastic adjustment plate 1332 from the primary adapter 131 or the secondary adapter 132. The cross-section of the limiting boss 1333 is trapezoidal and matches the limiting groove to lock the position of the elastic adjustment plate 1332. In order to facilitate the operator to move the elastic adjustment plate 1332, a moving groove 1334 is also provided on the end face of the elastic adjustment plate 1332 to facilitate the operator to move and adjust.

[0029] Sealing rings 134 are embedded at the connection between the split-type adapter unit and the pipe port 11, and at the splicing of adjacent split-type adapter units 13, in order to improve the sealing performance of the insulation jacket.

[0030] Working principle: When installing the outdoor pipe valve assembly insulation sleeve, firstly, disassemble the box 10 along the connecting seam on the side wall of the box 10. Move the two parts of the disassembled box 10 from below the pipe valve assembly to wrap around the valve assembly, so that the pipe passes through the pipe opening 11 of the box 10. Then, use adhesive buckles 12 to splice and fix the box 10. Next, select the corresponding diameter split-type adapter unit 13 according to the pipe diameter, align the main and auxiliary adapters 132 with the outer circumference of the pipe, and use the cooperation of the slider 133 and the inner wall groove of the pipe opening 11 to assemble the adapter unit into place. Multi-level adapter units can be sequentially inserted into the groove for splicing. Then, use the actuating groove 1334 at the end of the elastic adjusting plate 1332 to move the adjusting plate 1332. After adjusting to the target position, the trapezoidal limiting boss 1333 is embedded into the limiting groove of the inner wall of the adapter to lock the position. Finally, close the box cover 20 and fix it with adhesive buckles 12. At this time, the sealing rings 134 of the adapter unit, the pipe opening 11, and the adjacent adapter unit parts are squeezed to form a multiple seal.
