Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1 and 2, a bidirectional wave-absorbing and wave-preventing valve is of an integral structure or is formed by combining a plurality of module units a, and the integral structure and the module units a comprise a valve body assembly 1 and a valve core assembly 2.
The valve body assembly 1 includes: the valve plates 11 in each row are arranged at intervals along the first direction 12 to form a first gap 14, the valve plates 11 in each row are in one-to-one correspondence, and are arranged at intervals along the second direction 13 to form a second gap 15, the first direction 12 is perpendicular to the second direction 13, and the corresponding first gap 14 and second gap 15 between the two rows of valve plates 11 jointly form a circulation channel; a frame structure 16 for positioning each valve sheet 11; the spool assembly 2 includes: the valve core rods 21 are arranged on the frame structure 16, the length direction of the valve core rods 21 is arranged along the third direction 17, the third direction 17 is perpendicular to the first direction 12 and the second direction 13 respectively, each valve core rod 21 is arranged at the second gap 15 in the circulation channel, the valve core rods 21 are movably arranged in a set range in the second direction 13, and when the valve core rods 21 are forced to move, the valve core rods 21 can reach a position which is attached to the valve plate 11 on any side to block the circulation channel; the elastic reset structure 22 is installed on the frame structure 16, and provides elastic extrusion force for the valve core rod 21 at two sides of the second direction 13, and the elastic extrusion force drives the valve core rod 21 to be kept between the two rows of valve plates 11 and at a position spaced from the valve plates 11 at two sides.
The invention provides a bidirectional wave-absorbing explosion-proof valve which can replace a suspension pendulum type explosion-proof valve, a rubber pipe type explosion-proof valve and an explosion-proof overpressure exhaust valve and overcome the defects of the low-resistance explosion-proof valves, and has the following advantages:
the bidirectional wave-absorbing and explosion-proof valve can bear the action of shock waves in the second direction 13 in both directions, and the valve core rod 21 can move bilaterally in the second direction 13 and is attached to the valve plate 11 on any side.
The bidirectional wave-canceling explosion-proof valve is non-gravity sensitive and can be installed at any angle, and in the using process, only the second direction 13 is required to be the thickness direction of the valve, and the plane direction defined by the first direction 12 and the third direction 17 can be rotated at will, namely, the first direction 12 and the third direction 17 have no specific requirements, and are vertical, horizontal or have any included angle relative to the ground, but in the specific implementation process, the first direction 12 is a more conventional mode relative to the ground.
In the use process, the bidirectional wave-absorbing anti-explosion valve has good durability, all key components including the valve plate 11, the frame structure 16, the valve core rod 21 and the elastic reset structure 22 can adopt metal structures, the maintenance is avoided in the service life, the temperature resistance of a base material is more than or equal to 300 ℃, and the good structural strength can bear the impact of larger pressure.
Under normal conditions, the bidirectional wave-absorbing anti-explosion valve has better ventilation, air flows enter from one side of the flow channel, and flows out from the other side of the flow channel through the gap between the valve plate 11 and the valve core rod 21 in the second gap 15, so that the process can be performed bidirectionally, and the starting wind pressure and ventilation volume requirements of engineering can be effectively met. When any side generates shock waves, the valve core rod 21 is counterbalanced with the extrusion force from the elastic reset structure 22 under the action of the impact force, and moves in the second direction 13 when the impact force is larger than the extrusion force, and if the impact force is enough to enable the valve core rod 21 to be attached to the valve plate 11, the circulation channel is blocked; if the impact force moves the valve stem 21 but is insufficient to bring the valve stem 21 into engagement with the valve plate 11, the flow channel is only throttled to a certain extent.
As a preferable example of the above embodiment, as shown in fig. 3, the combination of the respective module units a is stacked in the second direction 13, and the respective flow channels in the adjacent two layers are correspondingly communicated. In this way the thickness of the modular unit a can be reduced and the final desired thickness obtained by stacking of multiple layers, which structure enables multiple layers of wave-cutting in the flow direction.
As another combination of the module units a, as shown in fig. 4 and 5, the combination of the module units a is juxtaposed in a planar direction composed of the first direction 12 and the third direction 17. The extension area of the module unit A can be reduced in the mode, the whole width of the final valve is obtained in a mode of splicing a plurality of blocks, the module unit A can be more convenient to process, assemble and transport, and meanwhile, the bidirectional wave-absorbing and wave-preventing valve with various areas can be obtained through combination.
In the implementation process, as shown in fig. 6, the combination of the two modes may be adopted, and each module unit a is stacked in the second direction 13, and in each layer of structure, a plurality of module units a are arranged in parallel, where the parallel direction is the first direction 12 and/or the second direction 13. In the present invention, when the combination of the module units a is adopted, the different module units a may be combined by the connection between the frame structures 16 of the module units a, or an additional connection frame may be provided, and the combination is realized by the manner that each module unit a is fixedly connected with the connection frame, so that a complete valve structure is obtained, and the above-mentioned forms capable of achieving the technical purpose of the present invention are all within the scope of protection of the present invention.
When the module units a are stacked in the second direction 13, as a preference of the above embodiment, as also shown in fig. 6, a plurality of module units a in each layer structure are connected as an integral door leaf by a door frame, one side of two adjacent layers of integral door leaves are rotatably connected, and the rotation angle is satisfied such that the integral door leaf which is not required to be used reaches a position of opening by rotation to release the wave-absorbing process.
In the above preferred scheme, the different layers can be rotationally connected through the hinge structure after the integral door leaf is obtained, so that the different layers can be opened or closed in a relative rotation mode, in the using process of the method, the rest layers can be kept in a using state after the set layers are rotationally opened, and the multi-layer valve in the method obtains a flexible using mode.
As another embodiment, a plurality of module units a in each layer of structure are connected into integral door leaves through door frames, two adjacent layers of integral door leaves are arranged in a relative linear movement mode, the linear movement direction is a first direction 12 or a third direction 17, and the linear movement meets the requirement that the integral door leaves which are not needed to be used can be opened through movement to release the wave-absorbing process.
In the above preferred solution, the linear movement may be specifically sliding, and by setting a fixed slideway, the position movement of each layer structure may be realized. Of course, the above-mentioned manner of rotational connection and linear movement is only one connection form of the multi-layer structure, so as to facilitate opening and closing of individual layers, but other manners of fixedly connecting adjacent layers in the second direction 13, such as through connection members, are also within the scope of the present invention.
In the installation process, as shown in fig. 5 and 6, the installation of the pre-buried frame 3 can be completed first, and then the installation of the integral bidirectional wave-absorbing and wave-preventing valve is carried out relative to the pre-buried frame 3.
As a preference of the above embodiment, as shown in fig. 7, a concave region 11a is provided on the valve sheet 11 on the side facing the valve core rod 21, the concave region 11a covering the full length range of the valve sheet 11; the cross section of the valve core rod 21 at least comprises two oppositely arranged arc-shaped contours, wherein the convex side of the arc-shaped contours faces the outer side of the valve and is used for guiding air flow into the concave area 11a. In the present invention, in order to reduce the weight of the product and to make the cost more controllable, the valve core rod 21 is preferably provided in a hollow structure. In practice, the valve plate 11 may be independent from the frame structure 16, in which case the valve plate 11 may be bent to form a recessed area 11a covering the full length of the valve plate 11, in which way the recessed area 11a may be provided with a greater width and depth at a lower cost; alternatively, the valve sheet 11 may be machined to obtain the recessed region 11a. In the above case, it is possible to make the valve sheet 11 have a U-shaped cross section for the structure of the valve sheet 11, either as a whole or by splicing a plurality of structures.
The cross-sectional forms of the two oppositely disposed arcuate profiles available for the valve core rod 21 are varied, such as the circular cross-section shown in fig. 1-4, or the elliptical cross-section, or the form of the profiles that together form the valve core rod 21 by arcuate and linear shapes as shown in fig. 5, etc. As shown in the bottom of fig. 6, the arc profile on one side of the attack shock wave can effectively guide the shock wave into the concave area 11a, and in the process of changing the direction of the shock wave in the concave area 11a, the energy can be reduced, when the shock wave reacts to the arc profile on the other side of the valve core rod 21, the reaction force is reduced, and the shock wave can also flow out to the other side of the valve under the guidance of the arc profile on the side; the above process occurs instantaneously, and the closing time of the valve core rod 21 under the action of the shock wave can be effectively reduced.
As a specific embodiment, each row of valve plates 11 is formed integrally with a portion of the frame structure 16, and the portions of the frame structure 16 are fixedly connected to form a whole by connecting members. As shown in fig. 2 and 8, in the above manner, the valve plate 11 and the frame structure 16 may be integrated by casting or the like, and then precise partial dimensions may be obtained by machining.
As a preferable example of the above embodiment, as shown in fig. 9, a straight hole 16a is provided on the frame structure 16 for the valve core rod 21 to penetrate and limit the set range by the edge; the elastic reset structure 22 comprises two elastic deflector rods 22a respectively positioned at two sides of the valve core rod 21 in the second direction 13; one end of the elastic deflector 22a is mounted to a fixed point on the frame structure 16, and the other end is a free end which is located within a set range in a natural state and is attached to the valve core rod 21.
In this structure, the movement guide of the valve core rod 21 can be realized through the straight hole 16a, the edge of the straight hole 16a is taken as the edge of the set range, and of course, in order to realize more stable linear movement of the valve core rod 21, additional guide structures such as a guide rod 22b penetrating the valve core rod 21 in the second direction 13 and the like can be further arranged; when the valve core rod 21 is pressed against the elastic deflector 22a by the impact wave, the elastic deflector 22a is elastically deformed, and the deformation may occur at a fixed point, at a free end, or both, thereby providing an elastic pressing force. In this way, the valve core rod 21 is conveniently installed, the valve core rod penetrates through the straight hole 16a on the frame structure 16, and the elastic deflector 22a can be installed on the outer side of the frame structure 16, so that the valve core rod is convenient to operate, and the assembly difficulty of the valve can be effectively reduced. In this way, a cover may be additionally provided to cover the portions of the stem 21 and the elastic lever 22a protruding from the surface of the frame structure 16, thereby ensuring the aesthetic appearance of the product, and the function of the cover herein may be also achieved by the above-described connection frame.
As a preference to the above embodiment, as shown in fig. 8 and 10, the elastic return structure 22 includes: the guide rod 22b is arranged along the second direction 13 in the length direction, two ends of the guide rod are fixedly connected with the frame structure 16, and a through hole is formed in the end part of the valve core rod 21 for the guide rod 22b to penetrate; the two return springs 22c are respectively sleeved at two ends of the guide rod 22b and are positioned between the fixed end of the guide rod 22b and the valve core rod 21.
In this structure, the movement guide of the valve core rod 21 is achieved by the guide rod 22b, and the limit compression position of the return spring 22c is set as the edge of the set range; when the valve core rod 21 is pressed against the return spring 22c by the shock wave, the return spring 22c is elastically deformed, thereby providing an elastic pressing force. In this way, both the spool rod 21 and the elastic restoring means can be mounted inside the frame structure 16, which is more attractive, and the frame structure 16 has a higher strength due to a stronger integrity. In this way, the fixing seat 22d is preferably used to fix the two ends of the guide rod 22b, the fixing seat 22d is only required to be mounted on the frame structure 16, and preferably, the fixing seat 22d can be specifically mounted between two adjacent valve plates 11, so that the relative distance between the two valve plates 11 can be stable; in the implementation process, it is further preferable that the valve plate 11, the fixing seat 22d and a part of the frame structure 16 can be integrally formed, such as a casting manner, so that the difficulty in assembling a plurality of structures is reduced while the integral strength is ensured.
