Description

Technical Field

[0001] The utility model relates to the technical field of civil air defense engineering, in particular to a high-strength pressure-resistant rubber hose type explosion-proof valve device. Background Art

[0002] Blast-proof valves are protective ventilation devices used in civil air defense projects to ensure uninterrupted ventilation during air raids. They are typically used in conjunction with diffusion chambers and are categorized by material: pendulum-type (also known as suspended plate-type) and hose-type. Hose-type blast-proof valves utilize a flexible rubber hose as the valve body. Under the impact of a shock wave, the hose rapidly deforms, closes, and tilts, blocking the shock wave and achieving its purpose. After the shock wave passes, the hose's elasticity quickly returns to its original shape, ensuring unobstructed ventilation.

[0003] In document CN202221359190.2, a hose-type explosion-proof wave valve that can resist negative pressure impact is proposed, which includes a wall, a mounting door frame, a hose-type explosion-proof wave valve, a hose, a gate valve, and a pressure relief groove. The mounting door frame is mounted inside the wall, and the hose-type explosion-proof wave valve is mounted inside the mounting door frame. The valve surface of the hose-type explosion-proof wave valve is equipped with a hose and a gate valve. Pressure relief grooves are provided at both ends of the mounting door frame. The mounting door frame is provided with a pressure relief mechanism that can relieve pressure on the hose-type explosion-proof wave valve and a fixing mechanism that further fixes the hose-type explosion-proof wave valve. The utility model provides a pressure relief mechanism, and through the coordinated use of the inner groove, pressure relief port, exhaust fan, anti-fool groove, hydraulic telescopic rod, groove plate, and anti-fool block, the other end of the hose-type explosion-proof wave valve can be relieved of pressure, so that the pressure at both ends is similar, so that a negative pressure environment will not be continuously generated, thereby fundamentally solving the harm of negative pressure impact to the door.

[0004] The hose-type explosion-proof wave valve that can resist negative pressure impact proposed in the above-mentioned cited document completes ventilation through the hose during daily use, and maintenance personnel need to regularly unscrew the hose from the threaded installation groove of the hose-type explosion-proof wave valve and replace the filter inside the hose. Since maintenance personnel only need to replace the filter inside the hose, the entire hose needs to be disassembled during the replacement process, which is inconvenient to use. Utility Model Content

[0005] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and in the abstract and title of the utility model to avoid obscuring the purpose of this section, the abstract and the title of the utility model, and such simplifications or omissions shall not be used to limit the scope of the present invention.

[0006] In order to solve the problem that maintenance personnel only need to replace the filter screen inside the hose, but the entire hose needs to be disassembled during the replacement process, which is inconvenient to use, the utility model provides the following technical solutions: a high-strength, pressure-resistant hose-type explosion-proof valve device, comprising an explosion-proof door body and a control component provided on one side of the outer wall of the explosion-proof door body, wherein one side of the outer wall of the explosion-proof door body is linearly and evenly spaced with a plurality of circular thread grooves, and the inner cavity of the circular thread groove is threadedly connected to a ventilation component;

[0007] The ventilation assembly includes a hose mechanism and a filter mechanism that is movably embedded in the inner cavity of the hose mechanism. The two ends of one side of the outer wall of the filter mechanism are magnetically connected to a collection mechanism. The filter mechanism is set to filter impurities in the air passing through the inner cavity of the hose mechanism, and the collection mechanism is set to collect fallen dust.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] As a preferred solution of A described in the present invention, the hose mechanism includes an embedded pipe and a mounting thread arranged in the middle of the outer wall of the embedded pipe, and a soft hose is fixedly installed at one end of the embedded pipe.

[0010] As a preferred solution of A described in the present invention, the filtering mechanism includes a fitting pipe and an embedded circular block fixedly installed in the middle of one side of the outer wall of the fitting pipe, and filter mesh layers are embedded on both sides of the inner cavity of the fitting pipe.

[0011] As a preferred solution of A described in the present invention, long rods are fixedly installed on both sides of one end of the pipe, an arc tube is fixedly installed on one end of the long rod, and an embedded magnetic groove is opened in the middle of the other side of the one end of the pipe.

[0012] As a preferred solution of A described in the present invention, the collecting mechanism includes an arc-shaped fitting block and an inserted magnetic block fixedly installed at one end of the arc-shaped fitting block.

[0013] As a preferred solution of A described in the present invention, an inclined feed trough is provided on one side of the upper end of the arc-shaped bonding block, and a scraping block is fixedly installed on one end of the notch of the inclined feed trough.

[0014] The beneficial effect of the present invention is that the operator drives the long rod and the fitting pipe to be pulled out from the inner cavity of the embedded pipe by pulling the arc pipe, and then the filter mesh layer arranged in the inner cavity of the fitting pipe can be taken out together. After cleaning the filter mesh layer, the fitting pipe is inserted into the inner cavity of the embedded pipe again, so that the middle part of the inner wall of the embedded round block and the mounting thread is provided with a circular card groove for card embedding, thus completing the fixed installation of the fitting pipe. Such a setting makes it easy for the operator to directly take out the filter mechanism from the inner cavity of the hose mechanism for cleaning, without the need to disassemble the hose mechanism, and is convenient to use.

[0024] Example

[0025] Reference Figures 1 to 4 , is an embodiment of the present utility model, which provides a high-strength pressure-resistant hose-type explosion-proof valve device, such as Figure 1-3 As shown, a high-strength, pressure-resistant hose-type explosion-proof valve device includes an explosion-proof door body 1 and a control component 2 opened on one side of the outer wall of the explosion-proof door body 1. A plurality of circular thread grooves 3 are linearly and evenly spaced on one side of the outer wall of the explosion-proof door body 1. A ventilation component 4 is threadedly connected in the inner cavity of the circular thread groove 3. The ventilation component 4 includes a hose mechanism 41 and a filter mechanism 42 that is movably embedded in the inner cavity of the hose mechanism 41. Collection mechanisms 43 are magnetically connected at both ends of one side of the outer wall of the filter mechanism 42. The filter mechanism 42 is configured to filter impurities in the air passing through the inner cavity of the hose mechanism 41, and the collection mechanism 43 is configured to collect fallen dust.

[0026] The hose mechanism 41 includes an embedded pipe 411 and a mounting thread 412 provided at the middle of the outer wall of the embedded pipe 411 . A soft hose 413 is fixedly mounted at one end of the embedded pipe 411 .

[0027] The filtering mechanism 42 includes a fitting pipe 421 and an embedded circular block 422 fixedly installed in the middle of one side of the outer wall of the fitting pipe 421. Filter mesh layers 423 are embedded on both sides of the inner cavity of the fitting pipe 421. A circular card groove is opened in the middle of the inner wall of the mounting thread 412, which is not shown in the figure. The fitting pipe 421 drives the embedded circular block 422 to be movably embedded in the inner cavity of the embedded pipe 411. The embedded circular block 422 and the circular card groove are snap-fitted and installed. The filter mesh layer 423 is set to filter the dust passing through.

[0028] Long rods 424 are fixedly installed on both sides of one end of the fitting pipe 421, and an arc tube 425 is fixedly installed on one end of the long rod 424. An embedded magnetic groove 426 is opened in the middle of the other side of one end of the fitting pipe 421. The long rod 424 and the arc tube 425 are used to drive the fitting pipe 421 to be taken out from the inner cavity of the embedded round block 422 for cleaning.

[0029] In this embodiment, when the operator needs to clean the filter screen in the inner cavity of the hose mechanism 41, the operator pulls the arc tube 425 to drive the long rod 424 and the fitting pipe 421 to be pulled out from the inner cavity of the embedded pipe 411, and then the filter screen layer 423 set in the inner cavity of the fitting pipe 421 can be brought out together. After the operator has cleaned the filter screen layer 423, the fitting pipe 421 can be inserted into the inner cavity of the embedded pipe 411 again, so that a circular card groove is provided in the middle of the inner wall of the embedded round block 422 and the installation thread 412 for card embedding, thereby completing the fixed installation of the fitting pipe 421. This arrangement makes it easy for the operator to directly remove the filter mechanism 42 from the inner cavity of the hose mechanism 41 for cleaning, without the need to disassemble the hose mechanism 41, and is convenient to use.

[0030] like Figure 4 As shown, the collecting mechanism 43 includes an arc-shaped fitting block 431 and an inserted magnetic block 432 fixedly installed at one end of the arc-shaped fitting block 431. The inserted magnetic block 432 is magnetically connected to the inner cavity of the embedded magnetic groove 426, which is convenient for the installation and disassembly of the arc-shaped fitting block 431. An inclined feed groove 433 is provided on one side of the upper end of the arc-shaped fitting block 431. A scraping block 434 is fixedly installed at one end of the groove of the inclined feed groove 433. The scraping block 434 is used to clean the inner wall of the embedded pipe 411, so that the cleaned dust falls into the inner cavity of the inclined feed groove 433 under the action of inertia.

[0031] In this embodiment, after the operator removes the fitting pipe 421 from the inner cavity of the embedded pipe 411, the operator can first rotate the arc tube 425 to drive the arc-shaped fitting block 431 to fit the inner wall of the embedded pipe 411 and rotate, so that the arc-shaped fitting block 431 drives the scraping block 434 to scrape the dust attached to the inner wall of the embedded pipe 411 during rotation, and then the dust falls into the slot of the inclined feed trough 433 and is collected, thereby cleaning the inner wall of the embedded pipe 411.
