Description

Technical Field

[0001] This utility model relates to an explosion-proof door, and more particularly to a dual-action diaphragm gravity explosion-proof door, belonging to the field of explosion-proof door technology. Background Technology

[0002] As disclosed in application number 202010800142.1, the door frame has several lock holes, and the door body has several telescopic lock heads that can be inserted into the lock holes. A transmission gear is installed inside the door body, and the transmission gear is connected to the telescopic lock heads. The door body has a through hole one and a through hole two. The through hole one has an internal thread one. A first circular plate is connected inside the cylindrical hole one. The first circular plate has an external thread one that mates with the internal thread one. The center of the first circular plate is connected to one end of a fixed shaft. The other end of the fixed shaft is connected to a second circular plate. A bearing is installed on the fixed shaft. A first gear is fitted on the outer ring of the bearing. A second gear is provided on each side of the first gear. A rotatable drive rod is provided on the first circular plate and the second circular plate. The end of the drive rod that extends into the door body is connected to a third gear. The prior art discloses the opening and closing structure of the lock, but it does not improve the structure of how the explosion-proof door is explosion-proof, nor can it realize multi-layer diversion and pressure relief and multi-layer explosion-proof operation.

[0003] Therefore, based on the above-mentioned shortcomings, a dual-action diaphragm gravity explosion-proof door is needed to optimize these shortcomings. Utility Model Content

[0004] The main purpose of this invention is to provide a dual-action diaphragm gravity explosion-proof door.

[0005] The objective of this utility model can be achieved by adopting the following technical solution:

[0006] A dual-action diaphragm gravity explosion-proof door includes an explosion-proof door body for sealing, wherein a flat sealing element is wrapped around the outside of the explosion-proof door body;

[0007] The explosion-proof door body has explosion-proof membrane one, explosion-proof membrane two and explosion-proof weight-increasing core distributed from the inside to the outside. The explosion-proof membrane one and explosion-proof membrane two have recessed flow guiding cavities distributed on them.

[0008] Preferably, mounting base one and mounting base two are symmetrically installed on both sides inside the explosion-proof door body. Explosion-proof membrane one is installed inside mounting base two, and explosion-proof membrane two and explosion-proof weight-increasing core are installed inside mounting base two.

[0009] Preferably, the explosion-proof weight-adding core is provided with a sealing pin that penetrates the body of the explosion-proof door.

[0010] Preferably, the second mounting base has a U-shaped structure, and the first mounting base has an E-shaped structure.

[0011] Preferably, mounting components are symmetrically installed at both ends of the outer side of the explosion-proof door body.

[0012] Preferably, the explosion-proof door body, explosion-proof membrane one, explosion-proof membrane two, explosion-proof weight-increasing core and sealing pin are assembled structures.

[0013] The beneficial technical effects of this utility model are as follows:

[0014] This utility model provides a dual-action diaphragm gravity explosion-proof door.

[0015] 1) The explosion-proof door body adopts a progressive assembly structure, with explosion-proof membrane one, explosion-proof membrane two and explosion-proof weight-increasing core installed sequentially from the inside out;

[0016] Among them, explosion-proof membrane one and explosion-proof membrane two constitute a two-layer superimposed pressure relief explosion-proof plate, which forms an initial protective barrier through dual synergy, effectively buffering the pressure relief impact force;

[0017] Based on this, the flow guide cavity precisely guides the direction of pressure relief, avoiding secondary impacts caused by disordered release;

[0018] The explosion-proof weight-adding core at the end further enhances the overall explosion-proof performance, forming a multi-dimensional protection system.

[0019] 2) In the internal structure of the explosion-proof door body, explosion-proof membrane one, explosion-proof membrane two and explosion-proof weight-increasing core are precisely limited and fixed by mounting base one and mounting base two. This design cleverly simplifies the assembly process, can quickly complete the component installation, and greatly improves the convenience of on-site construction.

[0020] When subjected to an explosive impact, the explosion-proof membrane and the flow guiding cavity form an efficient gas evacuation path, which can quickly guide the high-pressure gas generated by the explosion. During this process, the explosion-proof membrane and the flow guiding cavity work together to complete the pressure relief operation. Through the layered effect, multiple explosion protections are achieved. This multi-level pressure relief design not only ensures the orderliness of the pressure relief process, but also significantly improves the continuous protection capability of the explosion-proof door, effectively enhancing the safety redundancy of the equipment in complex explosive environments.

[0021] 3) The explosion-proof door body, explosion-proof membrane one, explosion-proof membrane two, explosion-proof weight-increasing core, and sealing pin are assembled. The top of the explosion-proof door body can be opened, and explosion-proof membrane one, explosion-proof membrane two, and explosion-proof weight-increasing core can be inserted into the explosion-proof door body in sequence and then fixed with screws. The sealing pin inside the explosion-proof weight-increasing core extends out of the outside of the explosion-proof door body for telescopic opening and closing. The explosion-proof structure in this equipment is a combined structure, which is convenient for replacement and maintenance and reduces costs. Attached Figure Description

[0037] Among them, explosion-proof membrane 12 and explosion-proof membrane 202 constitute a two-layer superimposed pressure relief explosion-proof plate, which forms an initial protective barrier through dual synergy and effectively buffers the pressure relief impact force.

[0038] Based on this, the flow guide cavity 201 precisely guides the direction of pressure relief, avoiding secondary impacts caused by disordered release;

[0039] The explosion-proof weight-adding core 104 at the end further enhances the overall explosion-proof performance, forming a multi-dimensional protection system.

[0047] When subjected to an explosive impact, the explosion-proof membrane 2 and the flow guiding cavity 201 form an efficient gas evacuation path, which can quickly guide the high-pressure gas generated by the explosion. During this process, the explosion-proof membrane 2 and the flow guiding cavity 201 work together to complete the pressure relief operation. Through the layered effect, multiple explosion protections are achieved. This multi-level pressure relief design not only ensures the orderliness of the pressure relief process, but also significantly improves the continuous protection capability of the explosion-proof door, effectively enhancing the safety redundancy of the equipment in complex explosive environments.
