DETAILED DESCRIPTION

[0030] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figure 1-Figure 3 : A low-noise safety valve includes a main body 1, which is covered with a sound insulation sleeve 2, and the sound insulation sleeve 2 is provided with sound insulation cotton for isolating noise; the side of the sound insulation sleeve 2 is connected to a mounting seat 21, and the mounting seat 21 is provided with a support 22; the support 22 is provided with a connecting mechanism 3, and the support 22 is connected to the main body 1 through the connecting mechanism 3.

[0032] The present invention utilizes a main body 1, a soundproofing sleeve 2, and a connecting mechanism 3 to reduce the noise and vibration generated during operation of the safety valve. This reduces noise pollution, minimizes the impact of vibration on the equipment, and improves user comfort and stability. This solves the problem of cumbersome assembly and disassembly and inconvenient maintenance associated with conventional safety valve soundproofing components. A mounting base 21 is provided with a support 22, which is provided with a connecting mechanism 3. Support 22 is connected to the main body 1 via the connecting mechanism 3. This connection ensures that the soundproofing sleeve 2 is stably mounted on the main body 1, ensuring that the soundproofing sleeve 2 and the soundproofing cotton remain functional. When the safety valve is operating, the soundproofing cotton and the soundproofing sleeve 2 work together to reduce noise and vibration. To clean or replace the soundproofing sleeve 2 or the soundproofing cotton, the support 22 is quickly disconnected from the main body 1 via the connecting mechanism 3, and the soundproofing sleeve 2 is removed for operation. After completion, the soundproofing sleeve 2 is quickly reattached to the main body 1 via the connecting mechanism 3, ensuring its continued functionality. The stable connection also prevents the soundproofing sleeve 2 from falling off during operation.

[0033] Reference Figure 1-Figure 5 : The connecting mechanism 3 includes a card block 31 and a control component 32; the card block 31 is slidably installed on the support 22, and a first elastic member 311 is provided on the card block 31, and the two ends of the first elastic member 311 are respectively connected to the card block 31 and the support 22; a rib plate 11 is provided on the main body 1, and a mounting groove for plugging and cooperating with the support 22 is provided on the rib plate 11, and a card slot cooperating with the card block 31 is provided in the mounting groove; the control component 32 is used to control the card block 31 to separate from the card slot.

[0034] The present invention realizes the rapid disassembly and assembly between the sound insulation sleeve 2 and the main body 1 through the clamping block 31, the control component 32 and the rib plate 11, while ensuring the function of the connection stability, achieving the effect of facilitating the maintenance and replacement of the sound insulation sleeve 2 and ensuring that it will not loosen or fall off when the safety valve is working, solving the problem that the traditional sound insulation components are complicated to disassemble and assemble, inefficient, and the unstable connection easily affects the sound insulation effect. When installing the sound insulation sleeve 2, the support 22 is inserted into the installation groove of the rib plate 11. During the process, the clamping block 31 is squeezed and slid toward the support 22, and the first elastic member 311 contracts. When the support 22 is fully inserted, the first elastic member 311 resets and pushes the clamping block 31 to slide into the clamping slot. The clamping block 31 cooperates with the clamping slot to fix the support 22 on the rib plate 11, and the sound insulation sleeve 2 is then firmly covered on the main body 1; at this time, the sound insulation cotton in the sound insulation sleeve 2 absorbs the vibration generated by the main body 1, and the sound insulation sleeve 2 blocks the noise transmission. To remove the sound insulation sleeve 2, the control assembly 32 controls the block 31 to separate from the slot, then pulls the support 22 out of the mounting slot. The sleeve 2 can then be removed for maintenance or replacement. Once the support 22 is reinserted into the mounting slot, the block 31, under the action of the first elastic member 311, snaps back into the slot, completing the installation. This entire process requires no complex tools, making assembly and disassembly quick and easy. The coordination between the block 31 and the slot ensures that the sound insulation sleeve 2 remains stably connected during operation.

[0035] Reference Figure 5-Figure 7 : The control component 32 includes an extension rod 321 and a push rod 322; the extension rod 321 is connected to the block 31, and an oblique guide groove 3211 is provided on the extension rod 321; the push rod 322 is slidably installed on the support 22, and the push rod 322 abuts against the oblique guide groove 3211; a pushing component 33 for controlling the movement of the push rod 322 is provided on the support 22. When the pushing component 33 pushes the push rod 322 to move toward the direction close to the extension rod 321, the push rod 322 squeezes the groove wall of the oblique guide groove 3211 to push the block 31 to move.

[0036] The application realizes the function of controlling the separation of the clamping block 31 and the clamping groove through simple operation by the extension rod 321, the push rod 322 and the pushing assembly 33, further simplifies the disassembly process of the sound insulation sleeve 2, achieves the effect of making the disassembly of the sound insulation sleeve 2 more labor-saving and convenient, improves the maintenance and replacement efficiency, solves the problems of complex and laborious unlocking operation of the traditional connecting mechanism 3, and affects the convenience of disassembly of the sound insulation component. When the sound insulation sleeve 2 needs to be disassembled, the pushing assembly 33 is operated, the pushing assembly 33 pushes the push rod 322 to move in the direction close to the extension rod 321, the push rod 322 extrudes the groove wall of the inclined guide groove 3211, the extension rod 321 drives the clamping block 31 to move away from the clamping groove, the clamping block 31 is separated from the clamping groove, at this time, the support 22 can be pulled out from the mounting groove of the rib plate 11, and the sound insulation sleeve 2 is removed; after the maintenance and replacement are completed, the support 22 is inserted into the mounting groove, the clamping block 31 is reset and clamped into the clamping groove under the action of the first elastic member 311, and the installation is completed; the cooperation of the pushing assembly 33, the push rod 322 and the extension rod 321 converts the linear motion of the push rod 322 into the lateral movement of the clamping block 31, so that the unlocking operation is more labor-saving, the whole disassembly process does not need complex tools, the convenience of maintenance and replacement of the sound insulation sleeve 2 is further improved, and meanwhile, the stable connection and sound insulation effect of the sound insulation sleeve 2 during work are not affected.

[0037] With reference to Figure 5-Figure 7 The pushing assembly 33 comprises a push plate 331 and a second elastic member 332; the push rod 322 is connected with one end of the push plate 331 away from the extension rod 321; and the two ends of the second elastic member 332 are connected with the push plate 331 and the support 22 respectively.

[0038] The present invention utilizes a push plate 331 and a second elastic member 332 to conveniently control the movement of the push rod 322 and assist in automatically resetting the push rod 322. This simplifies and reduces the effort required to assemble and disassemble the sound insulation sleeve 2 while ensuring the stability of the control assembly 32 for subsequent operation. This solves the problem of conventional push mechanisms requiring manual resetting after operation and resulting in inconvenience. A guide rod 333 is connected to the push plate 331 and slidably engages the support 22, guiding the movement of the push plate 331. When the locking cam 321 is unlocked, the locking cam 322 is unlocked and the locking cam 323 is unlocked, and the locking cam 323 is unlocked. When the locking cam 31 is in the direction away from the support 22, the push plate 331 drives the push rod 322 to reset, and the push rod 322 no longer squeezes the inclined guide groove 3211, and the clamping block 31 can be re-matched with the clamping groove under the action of the first elastic member 311; after the maintenance and replacement is completed, the support 22 is inserted into the installation groove, and the clamping block 31 is reset and clamped into the clamping groove under the action of the first elastic member 311 to complete the installation; the setting of the push plate 331 makes it easier to push the push rod 322, and the automatic reset function of the second elastic member 332 eliminates the step of manually adjusting the position of the push rod 322, further improving the convenience of disassembly and assembly of the sound insulation sleeve 2.

[0039] Reference Figure 2-Figure 4 and Figure 8 A clamping column 111 is provided on the rib 11, and a docking groove 211 that cooperates with the clamping column 111 is opened on the mounting seat 21.

[0040] The present invention realizes the function of quickly and accurately adjusting the installation position of the sound insulation sleeve 2 when installing it, and at the same time enhancing the installation stability of the sound insulation sleeve 2 through the clamping column 111 on the rib plate 11 and the docking groove 211 on the mounting seat 21, thereby greatly shortening the installation alignment time of the sound insulation sleeve 2, avoiding installation position deviation, and further improving the connection firmness between the sound insulation sleeve 2 and the main body 1, solving the problem of slow alignment and easy dislocation of sound insulation components in the traditional installation process, resulting in low installation efficiency and insufficient connection stability. When installing the sound insulation sleeve 2, first use the positioning effect of the clamping column 111 and the docking groove 211 to accurately align the docking groove 211 on the mounting seat 21 with the clamping column 111 on the rib plate 11, so that the clamping column 111 is quickly inserted into the docking groove 211. The relative position of the mounting seat 21 and the rib plate 11 is directly and accurately determined by the cooperation of the two, and the adjustment of the installation position of the sound insulation sleeve 2 is completed instantly, completely avoiding installation misalignment; then insert the support 22 into the mounting groove of the rib plate 11. During the process, the clamping block 31 is squeezed and slid toward the support 22, and the first elastic member 311 contracts. When the support 22 is fully inserted, the first elastic member 311 resets and pushes the clamping block 31 to slide into the clamping groove in the mounting groove. At this time, the clamping column 111 and the docking groove 211 are aligned. The positioning fit and the fixed fit of the block 31 and the slot form a double guarantee, firmly fixing the mounting seat 21 and the support 22 on the rib 11, and the sound insulation sleeve 2 is then accurately and firmly covered on the main body 1, the sound insulation cotton absorbs vibration, and the sound insulation sleeve 2 blocks noise; when the sound insulation sleeve 2 needs to be removed, the control component 32 controls the block 31 to separate from the slot, and then the docking slot 211 of the mounting seat 21 is disengaged from the post 111, and the sound insulation sleeve 2 can be removed; the positioning fit of the post 111 and the docking slot 211 not only allows the sound insulation sleeve 2 to quickly and accurately adjust its position during installation, greatly improving the installation efficiency, but also improves the connection stability together with the block 31 and the slot, ensuring that the sound insulation sleeve 2 will not loosen when the safety valve is working.

[0041] Reference Figure 8 : A third elastic member 112 is provided on the clamping column 111, and two ends of the third elastic member 112 are respectively connected to the clamping column 111 and the rib 11.

[0042] The present invention uses the third elastic member 112 on the clamping column 111 to achieve the functions of precise matching of the auxiliary clamping column 111 and the docking groove 211, buffering the installation impact, and compensating the gap to maintain stable positioning, thereby improving the convenience and accuracy of installation, reducing wear, and ensuring long-term positioning effects, solving the problem that traditional positioning structures are prone to wear and the accuracy decreases after long-term use. When installing the sound insulation sleeve 2, the docking groove 211 is aligned with the card column 111 and pushed. The docking groove 211 squeezes the card column 111, compressing the third elastic member 112. This compression process can not only buffer the installation impact, but also assist the card column 111 to quickly slide into the docking groove 211 under the elastic force of the third elastic member 112, and accurately position it; then the support 22 is inserted into the installation groove, and the block 31 squeezes the first elastic member 311. After the support 22 is in place, the first elastic member 311 pushes the block 31 to fit into the slot, and the card column 111 and the docking groove 211, and the block 31 and the slot are doubly fixed; during use, the third elastic member 112 compensates for the gap between the card column 111 and the docking groove 211 to maintain stability; when disassembling, the control component 32 makes the block 31 fall out of the slot, and the mounting seat 21 is pulled to let the docking groove 211 fall out of the card column 111 to remove the sound insulation sleeve 2 without affecting the disassembly and assembly efficiency and the stability of the connection.

[0043] Reference Figure 8 : A magnetic head is provided at one end of the clamping column 111 away from the rib 11, and a metal sheet for adsorbing the magnetic head is provided in the docking groove 211.

[0044] The present invention utilizes a magnetic head at one end of the post 111 away from the rib 11 and a metal sheet within the docking slot 211 to assist in the rapid alignment and adsorption of the post 111 and enhance positioning stability. This further improves installation efficiency, avoids positioning offset, and enhances the reliability of the positioning structure during long-term use. This solves the problem of traditional positioning structures relying on precise manual operation for alignment and being prone to temporary misalignment. When installing the sound insulation sleeve 2, the docking slot 211 is positioned close to the post 111, and the magnetic head and the metal sheet are attracted to each other, assisting in rapid alignment. The mounting base 21 is then pushed to slide the post 111 into the docking slot 211 for precise positioning. The support 22 is then inserted into the mounting slot, and the clamping block 31 squeezes the first elastic member 311. Once in position, the first elastic member 311 pushes the clamping block 31 into the slot, and the magnetic head and the metal sheet are attracted to each other.

[0045] Reference Figure 2 、 Figure 3 、 Figure 9 and Figure 10 The support 22 is detachably arranged on the mounting base 21 . An extension plate 221 is provided on the support 22 . The extension plate 221 is connected to the mounting base 21 via bolts 222 .

[0046] The present invention realizes flexible disassembly and assembly of the support 22 and the mounting base 21 by detachably setting the support 22 on the mounting base 21, facilitating the independent maintenance or replacement of the support 22 and the connecting mechanism 3, thereby reducing the maintenance cost of components and improving the overall service life of the device, and solving the problem that the traditional support 22 is fixedly connected to the mounting base 21 and needs to be replaced as a whole due to local damage. When the support 22 or the connecting mechanism 3 needs maintenance or replacement, the bolt 222 is unscrewed to remove the connection between the extension plate 221 and the mounting base 21, and the support 22 can be removed separately without disassembling the entire sound insulation sleeve 2; after maintenance is completed, the extension plate 221 is re-fixed to the mounting base 21 with the bolt 222, and then the support 22 is connected to the rib plate 11 through the connecting mechanism 3; this detachable structure not only ensures that the support 22 is firmly connected to the mounting base 21, but also makes the maintenance of local components more convenient.

[0047] Reference Figure 1 、 Figure 2 、 Figure 9 and Figure 10 : There are two mounting seats 21 on both sides of the sound insulation sleeve 2, each mounting seat 21 is provided with a support 22, and each support 22 is provided with a connecting mechanism 3 for connecting to the rib 11.

[0048] The present invention realizes the function of fixing the sound insulation sleeve 2 at multiple points on both sides, strengthening the stability of the connection between the sound insulation sleeve 2 and the main body 1, thereby preventing the sound insulation sleeve 2 from shaking during operation and ensuring the continuous and stable sound insulation effect, and solving the problem of traditional single-point or small number of connection points fixing and the sound insulation sleeve 2 being easy to loosen. During installation, each support 22 is first fixed to the corresponding mounting seat 21 through the extension plate 221 with a bolt 222, and then the connection mechanism 3 of each support 22 is operated separately, and the support 22 is inserted into the mounting groove on the rib plate 11. The clamping block 31 is clamped into the clamping slot under the action of the first elastic member 311, and the fixing is achieved at a total of four points on both sides of the sound insulation sleeve 2, so that the sound insulation sleeve 2 tightly covers the main body 1, the sound insulation cotton absorbs vibration, and the sound insulation sleeve 2 blocks noise.

[0049] Reference Figures 8-10 : A connecting rod 34 is provided on both sides of the sound insulation sleeve 2, and a support rod 341 is provided at both ends of each connecting rod 34. The two support rods 341 of the connecting rod 34 are respectively connected to the two push plates 331 on the two supports 22 on the same side of the sound insulation sleeve 2.

[0050] The sound insulation sleeve 2 is provided with a connecting rod 34 on each side, and the supporting rods 341 at the two ends of the connecting rod 34 are respectively connected to the two push plates 331 on the same side of the support 22, so that the push plates 331 of the two supports 22 on the same side are synchronously operated, the function of simplifying the unlocking step is realized, the efficiency of disassembling the sound insulation sleeve 2 is greatly improved, the problem of uneven stress caused by single-point operation is avoided, the problem of traditional operation of the push plates 331 one by one, time-consuming disassembly and the influence of components caused by asynchronous operation are solved. When the sound insulation sleeve 2 needs to be disassembled, one side of the connecting rod 34 is pushed, the connecting rod 34 synchronously drives the push plates 331 of the two supports 22 on the same side through the two supporting rods 341, the push plates 331 extrude the inclined guide grooves 3211 of the extension rods 321 to make the clamping blocks 31 out of the grooves, and the other side of the connecting rod 34 is operated in the same way, so that the four connecting mechanisms 3 on the two sides are synchronously unlocked, and it is not necessary to operate the push plates 331 one by one.
