Description

Technical Field

[0001] The invention relates to the technical field of multifunctional air valve equipment, and in particular to a vertically installed multifunctional air valve device. Background Art

[0002] At present, the tail gas discharged by the low-temperature methanol washing device in the coal chemical industry has large emission volume and complex composition. The VOCs concentration does not meet the conditions for continuous combustion but enters the explosion limit range. The VOCs concentration far exceeds the latest national environmental protection emission standards. Comprehensive treatment is extremely difficult. There is no successful treatment case at home and abroad. Therefore, it is necessary to develop a flameless thermal oxidation waste heat recovery energy-saving waste gas treatment device with low nitrogen, low fuel gas, high VOCs removal rate, low cost, large flow and high concentration VOCs concentration waste gas, to help enterprises in the industry get out of the dilemma of long-term inability to effectively treat large flow and high concentration waste gas. A multifunctional air valve is needed in the device, and the multifunctional air valve is a device for controlling gas flow. Its main function is to adjust and control the flow and direction of gas in ventilation, air conditioning, HVAC equipment and other systems. It can open, close or adjust the airflow in the ventilation duct as needed to meet the ventilation requirements of different occasions and needs. Common air valve types include butterfly air valves, flat air valves, square air valves, spherical air valves, etc. The multifunctional air valve plays a key role in controlling the airflow in the ventilation system, and has the advantages of simple structure and high reliability.

[0003] At present, a vertically mounted multifunctional air valve device is disclosed in patent announcement number "CN201410194331.3". The valve body frame is divided into two left and right channels by a central partition plate. Each channel is provided with a group of self-hanging movable blades that can only be opened in one direction. The self-hanging movable blades in the two channels are opened in opposite directions. The upper and lower ends of the valve body frame are respectively provided with two slideways. Each slideway is provided with a sliding valve plate. The size of the sliding valve plate is the same as the size of each channel opening. The flow direction of the airflow in the air valve is controlled and changed or the flow of the airflow is blocked by moving the two sliding valve plates and opening the self-hanging movable blades. The above scheme does not solve the problem of the air valve during maintenance.

[0004] However, the devices and prior art in the comparative documents still have the following defects when used:

[0005] 1. In order to extend the service life of the multifunctional air valve during daily use, the staff needs to regularly maintain the rotating parts inside the multifunctional air valve. The existing maintenance method is often performed manually by the staff. The multifunctional air valve needs to be powered on during daily operation. Therefore, the maintenance and repair needs to be performed after the power is turned off. Due to the negligence of the staff, safety accidents such as electric shock are very likely to occur, which may cause casualties and damage to the device in serious cases, which is not conducive to the smooth development of maintenance work.

[0006] 2. In addition, when the multifunctional air valve is maintained, the blades need to be turned over to an open state. Since there is a pressure difference between the closed multifunctional air valve and the outside, a shock wave will rush out at the moment the blades are opened, which increases the turning speed of the blades and easily causes harm to the staff. It will also cause damage to the blades, thereby reducing the safety of the maintenance process;

[0042] The top of the control box 302 is provided with an auxiliary protection mechanism that ensures that the device is in a power-off state before maintenance by means of the sliding action of the support rod 404;

[0043] The auxiliary protection mechanism includes an electrical box 401 fixedly connected to the top of the control box 302, a contact 1 402 is fixedly connected to one side of the bottom of the electrical box 401 close to the outer wall of the multifunctional air valve body 3, a bracket 403 is fixedly connected to the middle of the bottom of the electrical box 401, a support rod 404 is slidably connected to the inside of the bracket 403, an end of the support rod 404 away from the contact 1 402 is fixedly connected to a contact block 405, an end of the support rod 404 away from the contact block 405 is fixedly connected to a contact 2 406, and a contact 1 406 is fixedly connected to the outer wall of the control box 302.

[0044] Please refer to Figures 6 to 8 As shown, as a preferred embodiment, a buffer component is provided inside the multifunctional air valve body 3 to achieve a buffering effect when the blade 303 is opened through the sliding action of the pressure rod 903;

[0045] The buffer assembly includes a buffer cylinder 901 symmetrically fixedly connected to the inner wall of the bottom end of the multifunctional air valve body 3. The two buffer cylinders 901 are filled with a non-Newtonian fluid 902. A pressure rod 903 is slidably connected to the inside of the buffer cylinder 901. A secondary connecting rod 904 is hinged on the top of the pressure rod 903. The end of the secondary connecting rod 904 away from the pressure rod 903 is hinged to the outer wall of the central axis 301. As the pressure rod 903 is slowly pressed down, the non-Newtonian fluid 902 is used to better buffer the pressure rod 903. By reducing the descending speed of the pressure rod 903, the central axis 301 and the blade 303 are slowly flipped. When the staff maintains the blade 303, the shock wave caused by the different pressures inside and outside the device is avoided from rushing out from the inside of the multifunctional air valve body 3 to cause harm to the staff, thereby improving the safety of the maintenance process.

[0046] Please refer to Figures 9 to 11 As shown, as a preferred embodiment, auxiliary installation mechanisms are provided around the top of the mounting base 2 to achieve the fixing of the multifunctional air valve body 3 through the tightening action of the threaded rod 608;

[0047] The auxiliary installation mechanism includes a fixing frame 601 fixedly connected to the top of the installation base 2, a long plate 602 is slidably arranged inside the fixing frame 601, a long groove 603 is provided on the side wall of the long plate 602, a block 604 is fixedly connected to the side wall of the fixing frame 601 and located inside the long groove 603, a first spring 605 is fixedly connected to the outer wall of the block 604, one end of the first spring 605 away from the block 604 is fixedly connected to the side wall of the long groove 603, a fixing block 606 is arranged above the long plate 602, a threaded hole 607 is provided on the top of the long plate 602, a threaded rod 608 is inserted into the fixing block 606 and the threaded hole 607, a vertical plate 701 is fixedly connected to the top of the fixing frame 601, and a fixing Block 606 is slidably connected to the outer wall of the vertical plate 701, and the top of the vertical plate 701 is fixedly connected to a support plate 702, and the bottom of the support plate 702 is fixedly connected to a second spring 703, and the bottom end of the second spring 703 is fixedly connected to the top of the fixed block 606. The outer wall of the bottom end of the multifunctional air valve body 3 is hinged with a support ear 9, and four support ears 9 are evenly arranged. By lowering the height of the fixed block 606, the support ear 9 can be pressed on the surface of the long plate 602, thereby achieving the purpose of installing and fixing the multifunctional air valve body 3. Through a fast and efficient positioning and installation method, it can replace the existing installation method, which saves installation time and also helps to ensure the stability of the multifunctional air valve body 3 during subsequent use.

[0048] Please refer to Figure 12 to Figure 14 As shown, as a preferred embodiment, a sealing mechanism is also provided on the top of the mounting base 2 to improve the sealing performance through the downward pressing and upward bending action of the pressing plate 802;

[0049] The sealing mechanism includes a sandwich sealing ring 801 fixedly connected to the top of the mounting base 2, four pressing plates 802 are evenly inserted inside the sandwich sealing ring 801, four mounting plates 803 are evenly fixedly connected to the top of the equipment body 1, and one end of the four pressing plates 802 away from the sandwich sealing ring 801 is rotatably connected to the top outer wall of the mounting plate 803, and a support foot 804 is fixedly connected to the outer wall of the bottom end of the multifunctional air valve body 3, and a pressing block 805 is fixedly connected to the bottom of the support foot 804. The cross-sectional shape of the sandwich sealing ring 801 is U-shaped, and the number of pressing plates 802, mounting plates 803, support feet 804, and pressing blocks 805 is the same. By moving the pressing plate 802 upward, the sandwich sealing ring 801 is supported from a flat state, thereby increasing a larger surface area, realizing a comprehensive blocking of the gap between the bottom of the multifunctional air valve body 3 and the top of the mounting base 2, which helps to improve the sealing effect. The better sealing effect facilitates the multifunctional air valve body 3 to better control the airflow entering.

[0050] Please refer to Figure 5 As shown, as a preferred embodiment, the outer contour of the contact block 405 is arc-shaped, the contact block 405 is in abutment with the rotating disk 408, and two No. 1 support columns 501 are symmetrically fixedly connected to the bottom of the bracket 403, and the bottom of the support rod 404 close to the contact 2 406 is fixedly connected to the No. 2 support column 502, and a rubber band 503 is fixedly connected between the two No. 1 support columns 501 and the No. 2 support column 502. When the grooves on the rotating disk 408 are not in contact with the contact block 405, at this time, under the rebound action of the rubber band 503, the support rod 404 brings the contact 2 406 back to its original position and contacts the contact 1 402 again, so that the device can operate normally and is also convenient for the next maintenance.

[0051] The following are the complete usage steps and working principles of the above embodiment:

[0052] When the device is in use, in order to increase the service life of the multifunctional air valve body 3, the staff needs to regularly maintain the components inside the multifunctional air valve body 3. During maintenance, the staff needs to manually control the opening and closing of the blade 303 by holding the handle 409 and turning it, so that the blade 303 rotates inside the multifunctional air valve body 3 along with the central axis 301, so that the blade 303 changes from a closed state to an open state. During this process, the rotating disk 408 rotates along with the central axis 301. Since the inner wall of the rotating disk 408 is evenly provided with grooves, the contact block 405 is caused to slide with the support rod 404 inside the bracket 403 toward the side of the central axis 301 through the contact between the rotating disk 408 and the contact block 405. At the same time, when the support rod 404 slides, the second support column 502 fixedly connected to its bottom will stretch the rubber band 503. When the support rod 404 carries the contact point 2 406 in the electrical The bottom of the air box 401 slides toward the side of the multifunctional air valve body 3. At this time, the contact 2 406 is separated from the contact 1 402, so that the circuit of the device is disconnected, thereby achieving the purpose of powering off before the device is maintained, avoiding safety accidents caused by the negligence of the staff when the device is maintained without powering off, ensuring the personal safety of the staff during the maintenance process, and avoiding damage to the device caused by human factors. In addition, when the contact block 405 is in the groove position provided on the rotating disk 408, at this time, since the contact block 405 is not squeezed by the outer wall of the rotating disk 408, the support rod 404 is reset with the contact 2 406 under the rebound effect of the rubber band 503, and contacts with the contact 1 402 again, so that the device can operate normally, and it is also convenient for the next maintenance. By regularly maintaining the device, it helps to extend the service life of the multifunctional air valve body 3;

[0053] In addition, during the maintenance process, when the blade 303 turns over inside the multifunctional air valve body 3 along with the central axis 301, the two-stage connecting rod 904 hinged to the outer wall of the central axis 301 bends downward, and at the same time, the two-stage connecting rod 904 pushes the pressure rod 903 to slide downward inside the buffer cylinder 901. When the pressure rod 903 slides downward inside the buffer cylinder 901, its bottom will contact the non-Newtonian fluid 902. Since the non-Newtonian fluid 902 has the characteristics of being in a fluid state when the shear stress is small and being in a solid state when the shear stress is large, as the pressure rod 903 is slowly pressed down, the non-Newtonian fluid 902 plays a better buffering role on the pressure rod 903. By reducing the descending speed of the pressure rod 903, the central axis 301 and the blade 303 can be slowly turned over, and when the staff maintains the blade 303, the shock wave caused by the different pressures inside and outside the device is prevented from rushing out from the inside of the multifunctional air valve body 3 to cause harm to the staff, thereby improving the safety of the maintenance process.

[0054] In addition, when the multifunctional air valve body 3 is installed, it is necessary to perform precise installation to ensure the stability of the multifunctional air valve body 3 during subsequent use. The traditional installation method often takes a long time to adjust the installation position of the multifunctional air valve body 3, so it is time-consuming and labor-intensive. By evenly arranging four long plates 602 on the top of the installation base 2, when the multifunctional air valve body 3 falls to the top of the installation base 2, an extrusion force is generated on the long plates 602, so that the long plates 602 slide inside the fixing frame 601, and at the same time, the block 604 slides inside the long groove 603 and squeezes the first spring 605. This facilitates the subsequent removal of the multifunctional air valve body 3, so that the long plates 602 can be reset to facilitate the next use. When the long plates 602 slide inside the fixing frame 601, the bottom of the threaded rod 608 slides on the top of the long plates 602. Since the bottom end of the threaded rod 608 is not inserted into the threaded hole 607, the staff observes the position of the ear 9 at this time and can adjust the installation position of the multifunctional air valve body 3 by rotating it. Four ears 9 are arranged on the outer wall at the bottom end of the air valve body 3. In the daily installation process, only one of the ears 9 needs to be placed on the surface of the long board 602 to complete the accurate positioning and installation of the multifunctional air valve body 3. Then, the bottom end of the threaded rod 608 is inserted into the threaded hole 607. The above process can be carried out simultaneously. At this time, the staff only needs to use a wrench or other tools to tighten the threaded rod 608 and the threaded hole 607. During the tightening process, the fixing block 606 is subjected to downward pressure, so that the fixing block 606 slides downward on the outer wall of the vertical plate 701, and at the same time cooperates with the support plate 702 to stretch the second spring 703. Here, it is convenient for the multifunctional air valve body 3 to be reset after disassembly, and it is convenient for the next use. After the fixing block 606 is lowered, the ear 9 can be fixed on the surface of the long board 602, thereby achieving the purpose of installing and fixing the multifunctional air valve body 3. Through a fast and efficient positioning and installation method, it can replace the traditional installation method, saving installation time, and also helping to ensure the stability of the multifunctional air valve body 3 in the subsequent use process;

[0055] Before the bottom of the multifunctional air valve body 3 contacts the top of the mounting base 2, it will first contact the surface of the interlayer sealing ring 801. At the same time, the support foot 804 fixedly connected to the outer wall of the bottom end of the multifunctional air valve body 3 with the pressure block 805 will contact the top of the end of the pressure plate 802 close to the mounting plate 803. Since the pressure plate 802 is rotatably connected to the mounting plate 803, when the pressure block 805 presses the pressure plate 802 downward, the end of the pressure plate 802 away from the interlayer sealing ring 801 moves downward, thereby causing the end of the pressure plate 802 close to the interlayer sealing ring 801 to move upward. The upward movement of the pressure plate 802 supports the interlayer sealing ring 801 from a flat state, thereby increasing a larger surface area, achieving a comprehensive blockage of the gap between the bottom of the multifunctional air valve body 3 and the top of the mounting base 2, which helps to improve the sealing effect. The better sealing effect facilitates the multifunctional air valve body 3 to better control the airflow entering.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
