Description

Technical Field

[0001] This invention relates to the field of protective equipment in protective engineering, and in particular to a prefabricated modular ventilation valve base. Background Technology

[0002] Blast wave shields are protective devices installed at the inlets and outlets of air and smoke ducts in protected engineering projects to block or weaken blast waves. They are normally open to ensure normal ventilation; when the ventilation opening is subjected to an explosive impact load, the shield closes rapidly under the force of the blast wave, thereby ensuring the safety of equipment and personnel inside the project.

[0003] The valve base is a crucial component of a ventilation valve. Serving as the platform for the valve's shock wave absorption unit, it primarily bears the shock wave load and transfers the load to the door frame and wall structure. Ventilation volume is a key functional indicator of the valve, and its magnitude is mainly related to the ventilation area. In engineering practice, measures to increase the ventilation area are generally achieved through base structure design and optimization of the valve's ventilation openings.

[0004] Existing blast wave valve bases typically employ flat, spherical, arched, and drum-shaped structural designs. Flat bases suffer from drawbacks such as difficulty in increasing ventilation volume, inability to withstand lateral shock waves, and unfavorable load-bearing capacity between the base and the door frame wall. Spherical, arched, and drum-shaped bases can improve valve ventilation performance, allowing for a greater number of valve wave-damping units within a limited space, significantly increasing the ventilation volume of the valve protection equipment. Compared to arched designs, spherical and drum-shaped designs can accommodate more valves; however, considering the complexity of manufacturing spherical and drum-shaped designs, they can only be produced through integral casting, which is difficult to control for defects, resulting in a high scrap rate. Therefore, the arched base structure design becomes the optimal choice.

[0005] Because the arched valve base is quite large, a special forging mold is required if an integral processing solution is adopted. This makes the manufacturing process difficult, complex, and requires large-scale machining equipment with a long cycle, which is not conducive to reducing manufacturing costs. It is also not conducive to transportation and installation, and increases the difficulty and danger of construction. Summary of the Invention

[0006] The purpose of this invention is to provide an assembled modular ventilation valve base. The base adopts a modular design, which significantly reduces the manufacturing cost and transportation and installation difficulty of the valve. The base has high ventilation volume and excellent load-bearing capacity.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A modular prefabricated ventilation valve base includes multiple base modules and connectors. The multiple base modules are assembled from bottom to top to form the valve base, and adjacent base modules are connected by the connectors. Each base module has mounting holes for installing a valve shock absorption unit. The valve shock absorption unit can close when subjected to a shock wave.

[0008] Furthermore, in the above-mentioned prefabricated modular ventilation valve base, the cross-section of the base module is a fan ring; the axis of the mounting hole is parallel to the radial direction of the base module.

[0009] Furthermore, in the above-mentioned prefabricated modular ventilation valve base, the connector includes a connecting column and a connecting block. There are two connecting columns, which are respectively connected to both ends of the connecting block along its length. The connecting block is a cuboid, and the connecting column is a cylinder. The diameter of the connecting column is greater than the width of the connecting block. The connecting column and the connecting block are an integral structure.

[0010] Furthermore, in the above-mentioned prefabricated modular ventilation valve base, a connecting groove is provided on the contact surface of two adjacent base modules, and the two corresponding connecting grooves on the two base modules are arranged opposite each other; the shape of the two corresponding connecting grooves on the two base modules after being spliced ​​together is adapted to the shape of the connector.

[0011] Furthermore, in the above-mentioned prefabricated modular ventilation valve base, a through hole is provided on the connecting column, and a bolt hole is provided in the connecting groove on the base. After the connecting bolt passes through the through hole on the connecting column, it can be screwed into the bolt hole in the connecting groove; a washer is fitted on the connecting bolt.

[0012] Furthermore, in the above-mentioned prefabricated modular ventilation valve base, a plurality of connectors are provided at the connection point of two adjacent base modules and on the outer surface of the valve base; a plurality of connectors are provided at the connection point of two adjacent base modules and on the inner surface of the valve base; the plurality of connectors are evenly distributed along the arc direction of the base module.

[0013] Furthermore, in the above-mentioned prefabricated modular ventilation valve base, multiple rows of mounting holes are provided in the height direction of the base module, each row is provided with several mounting holes, and the mounting holes in each row are evenly distributed along the arc direction of the base module; adjacent rows of mounting holes are staggered; and the row spacing of the multiple rows of mounting holes is consistent.

[0014] Furthermore, in the aforementioned prefabricated modular ventilation valve base, the base module is provided with three rows of mounting holes.

[0015] Furthermore, in the above-mentioned prefabricated modular ventilation valve base, a groove with a fan-shaped cross-section is provided on one of the contact surfaces of two adjacent base modules along the arc direction of the base module, and a protrusion adapted to the groove is provided on the other contact surface; a lifting hole is provided in the groove.

[0016] Furthermore, in the above-mentioned prefabricated modular ventilation valve base, a door-type blast wave valve is formed by installing a lock, hinge, and jack on the valve base, or a sealing blast wave valve is formed by setting a fixed connection structure on the side of the valve base.

[0017] Analysis reveals that this invention discloses a modular prefabricated ventilation valve base. This base employs a modular structure, significantly reducing manufacturing, transportation, and installation costs, shortening the processing cycle, and allowing for flexible configuration of the number of base modules according to the valve's airflow requirements. This enhances the valve's adaptability to different projects and ventilation opening sizes. The valve base, composed of arc-shaped base modules, increases the number of valves that can be arranged within a limited space, while also improving load-bearing capacity and reducing the load-bearing pressure on the door frame wall. The mounting holes for the valve's wave-damping units are arranged in a staggered symmetrical pattern. Within a limited space, while ensuring strength, this arrangement achieves effective installation of the wave-damping units and maximizes the number of units that can be installed. The linear symmetrical layout facilitates machining on large milling machines, improving production quality and efficiency, and enhancing the overall compactness of the valve base structure.

[0028] like Figures 1 to 6 As shown, according to an embodiment of the present invention, a modular prefabricated ventilation valve base is provided, such as... Figure 1As shown, the valve base includes multiple base modules 1 and connectors 2. The base modules 1 are assembled sequentially from bottom to top to form the valve base, and adjacent base modules 1 are connected by several connectors 2. Each base module 1 has mounting holes 3 for installing the valve's shock absorption unit. The shock absorption unit can quickly close when impacted by a shock wave, blocking the shock wave from entering the structure and ensuring the safety of personnel and equipment inside. This valve base adopts a modular structure; multiple base modules 1 of fixed height are sequentially assembled to form the entire valve base. Reliable connections between different base modules 1 are achieved through connectors 2, significantly reducing the manufacturing, transportation, and installation costs of the valve base, shortening the processing cycle, and allowing for flexible configuration of the number of base modules 1 according to the valve's airflow requirements, enhancing the valve's adaptability to different projects and ventilation opening sizes. Each base module 1 is assembled via connectors 2, installed from bottom to top, first completing the installation of the bottommost base module 1, then stacking the other base modules 1 one by one, and finally installing the connectors 2 between each base module 1. Each base has a fixed design air volume. In actual use, the number of base modules 1 can be adjusted according to the total air volume requirement to meet the construction and use needs of different projects.

[0029] Furthermore, such as Figure 2 As shown, the cross-section of base module 1 is a fan-shaped ring; the axis of mounting hole 3 is parallel to the radial direction of base module 1, and the valve shock absorption unit is built into mounting hole 3. Compared with flat valve base, the valve base composed of base module 1 with a fan-shaped arc arch structure can carry a large number of valve shock absorption units, thereby increasing the design air volume of the blast wave valve (the ventilation area and air volume of a single valve shock absorption unit are fixed at a fixed wind speed, so the more valve shock absorption units the valve base can carry, the greater its design air volume). Since the valve base with an arc arch structure can improve the load-bearing capacity and reduce the load-bearing pressure on the door frame wall, the thickness of the door frame wall can be reduced, thereby improving the economy of civil construction.

[0030] Furthermore, such as Figure 3 and Figure 4As shown, the connector 2 includes a connecting post 4 and a connecting block 5. Two connecting posts 4 are provided, each connecting to one end of the connecting block 5 along its length. The connecting block 5 is a cuboid, and the connecting post 4 is a cylinder. The diameter of the connecting post 4 is larger than the width of the connecting block 5. The connector 2 is a single-piece structure. Connecting grooves 6 are provided on the contact surfaces of two adjacent base modules 1, with corresponding connecting grooves 6 on the two base modules 1 facing each other. The shape of the corresponding connecting grooves 6 on the two base modules 1 after assembly matches the shape of the connector 2 (one connecting post 4 of the connector 2 is located in one connecting groove 6 of one base module 1, and the other connecting post 4 of the connector 2 is located in one connecting groove 6 of the other base module 1). A through hole 9 is provided on the connecting post 4, and a bolt hole is provided in the connecting groove 6 on the base. The connecting bolt 7 passes through the through hole 9 on the connecting post 4 and can be screwed into the bolt hole in the connecting groove 6. A washer 8 is fitted on the connecting bolt 7. The cuboid-shaped connecting block 5 and the cylindrical connecting column 4 together form a spindle-shaped connector 2, which can be embedded in the connecting groove 6 on the base module 1. The circular outer surfaces at both ends of the connector 2 can reduce local stress concentration after being loaded.

[0031] Furthermore, to ensure connection strength, the connectors 2 are arranged at fixed angles on the outer and inner surfaces of the valve base along the arc direction of the valve base. That is, several connectors 2 are provided at the connection points of two adjacent base modules 1 on the outer surface of the valve base; several connectors 2 are provided at the connection points of two adjacent base modules 1 on the inner surface of the valve base; the several connectors 2 are evenly distributed along the arc direction of the base module 1.

[0032] Furthermore, multiple rows of mounting holes 3 are provided in the height direction of the base module 1, with several mounting holes 3 in each row. The mounting holes 3 in each row are evenly distributed along the arc direction of the base module 1; the mounting holes 3 in adjacent rows are staggered; and the row spacing of the multiple rows of mounting holes 3 is consistent. In one embodiment of the present invention, the base module 1 is provided with three rows of mounting holes 3. The distance between the center point of the mounting hole 3 in the uppermost row and the upper surface of the base module 1 is equal to the distance between the center point of the mounting hole 3 in the lowermost row and the lower surface of the base module 1; the row spacing between the mounting holes 3 in the uppermost row and the middle row is equal to the row spacing between the mounting holes 3 in the lowermost row and the middle row. The multiple rows of mounting holes 3 are arranged in an alternating manner in the base module 1. While ensuring strength, this arrangement can increase the number of valve shock absorption units within a limited space, significantly improving the valve airflow. At the same time, the linear symmetrical layout facilitates machining on large milling machines and improves the overall structural compactness.

[0033] To maximize airflow, as many mounting holes 3 as possible should be arranged on a single base module 1. However, increasing the number of holes will inevitably reduce the strength of the valve base. Therefore, to ensure load-bearing performance, the spacing between the mounting holes 3 should not be too small. Figure 6 As shown, to increase the number of valve shock absorber units installed, a staggered symmetrical arrangement method is adopted. The row spacing between multiple rows of mounting holes 3, the distance between the uppermost row of mounting holes 3 and the upper surface of the base module 1, and the distance between the lowermost row of mounting holes 3 and the lower surface of the base module 1 are all the same. This ensures that the base module 1 has a uniform structure, good load-bearing capacity, and is easy to process and position. It can achieve multi-axis synchronous processing on a large machining platform, improving processing quality and efficiency. To ensure the uniform strength of the hole wall structure of the mounting holes 3, the axis of each mounting hole 3 in each row is parallel to the radial direction of the base module 1, and the mounting holes 3 are evenly distributed from the center of the base module 1 to both sides.

[0034] Furthermore, such as Figure 5 and Figure 6 As shown, a groove 10 with a fan-shaped cross-section is provided on one of the contact surfaces of two adjacent base modules 1 along the arc direction of the base module 1, and a protrusion 11 adapted to the groove 10 is provided on the other contact surface; a lifting hole 12 is provided in the groove 10. To ensure the stable connection between the base modules 1 and to ensure that the valve base can bear the load as a whole when subjected to shock wave load, in addition to being fixed by the connector 2, the contact surfaces of two adjacent base modules 1 are respectively provided with a groove 10 and a protrusion 11, so that the base module 1 can be tightly fitted with the groove 10 by the protrusion 11 during assembly. In addition, for the convenience of installation and transportation, a lifting hole 12 is provided at each of the two ends of the groove 10 near the base module 1. The lifting hook uses the lifting hole 12 on the base module 1 to transport or lift the base module 1. After installation, the lifting hook is removed without affecting the assembly of the bottom modules. The connecting groove 6 provided on the base module 1 adopts a countersunk type, which improves the connection strength and ensures that the surface of the base module 1 is flat and beautiful after assembly. The above connection scheme can ensure the overall structural strength of the valve base and facilitate disassembly and assembly, reducing the difficulty of installation, maintenance and repair of the valve base.

[0035] Furthermore, by installing a lock, hinge, and jack on the valve base, a gate-type blast wave breaker can be formed, or a fixed connection structure can be set on the side of the valve base to form a sealing-type blast wave breaker.

[0036] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects: (1) The valve base adopts a modular structure, which greatly reduces the manufacturing, transportation and installation costs of the valve and shortens the processing cycle. At the same time, the corresponding number of base modules 1 can be flexibly set according to the air volume requirements of the valve, which enhances the adaptability of the valve to different projects and different ventilation opening sizes.

[0037] (2) The valve base composed of the arc-shaped arched base module 1 can increase the number of valves in a limited space, while improving the load-bearing capacity and reducing the load-bearing pressure on the door frame wall; the mounting holes 3 of the valve wave-damping unit adopt an interlaced symmetrical arrangement. In a limited space, while ensuring strength, it not only realizes the effective installation of the valve wave-damping unit, but also maximizes the number of valve wave-damping units that can be installed. The linear symmetrical layout is convenient for large milling machine processing, improves production quality and efficiency, and improves the overall compactness of the valve base structure.

[0038] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
