Therefore, the valve body is an important equipment for controlling the gas flow in and out of the regenerative thermal oxidizer.

[0004] In the above scheme, the valve can be opened and closed only by turning the hand wheel, which makes the automation rate of the device low. Secondly, the gas can only move in one direction in the device, and the function is single. If the gas in and out of the thermal oxidation furnace is to be controlled, two sets of such devices need to be installed, which not only increases the investment cost of the device, but also takes a lot of time to install, reducing the practicality of the device.

Secondly, two groups of ventilation chambers are arranged in the device, and the two groups of ventilation chambers can independently cut off and restore the gas flow, thereby integrating the function of controlling the gas in and out of the heat storage type organic waste gas oxidation furnace, improving the diversity of the device functions, and making the device more practical.

[0007] Preferably, a butt joint is threadedly connected to the end of the piston rod of the cylinder, and a butt joint groove for engaging the butt joint is provided at the other end of the movable rod; The butt joint and the butt groove cooperate to facilitate installation and disassembly between the cylinder and the movable rod.

[0008] Preferably, the valve head includes a main head shell, a sealing gasket fixedly sleeved on the main head shell, one end of the movable rod is plugged into the main head shell, two sets of rocker arms cross-arranged in the main head shell, a fan-shaped plate fixedly connected to one end of the rocker arm, a swivel shaft rotatably connected to one end of the rocker arm, the swivel shaft is fixedly installed in the main head shell, the fan-shaped plate is plugged into a T-shaped pressure block, two sets of springs symmetrically distributed in the main head shell, one end of the spring is connected to the rocker arm, and the other end of the spring is connected to the inner wall of the main head shell, two sets of limit plates symmetrically fixedly installed in the main head shell, the limit plates are used to block the rocker arm, and the two sets of rocker arms A first rectangular groove is opened on each of the movable rods, a receiving shaft is arranged in the other end of the movable rod, the receiving shaft passes through the two groups of first rectangular grooves, two groups of movable grooves are symmetrically opened on the outer ring of the main head shell, the T-shaped pressure block is movably inserted into the movable groove, second rectangular grooves are opened on both sides of one end of the T-shaped pressure block, a pin is arranged on the fan-shaped plate, and both ends of the pin are respectively located in the two groups of second rectangular grooves, two groups of brackets are symmetrically arranged on both sides of the main head shell, the brackets are fixedly installed in the ventilation cavity, a pressure column is rotatably installed in one end of the bracket, and an inverted slope for squeezing the pressure column is arranged on the other end of the T-shaped pressure block; When the movable rod loses the push of the cylinder, under the action of the spring force, the two sets of rocker arms will fit tightly against the two sets of limit plates, so that the other end of the T-shaped pressure block cannot be retracted into the movable groove, ensuring that in the event of a cylinder failure, the entire valve head still maintains a good seal against the sealing port, preventing untreated organic waste gas from leaking to the outside.

[0009] Preferably, the bracket includes an outer frame, one end of the outer frame is fixedly connected to the valve body, an inner frame is movably installed in the outer frame, the pressure-bearing column is rotatably installed in one end of the inner frame, and a screw is rotatably connected to the other end of the inner frame, the screw is threadedly connected to the outer frame, and two groups of linkage mechanisms are symmetrically arranged on the outer ring of the valve body, the linkage mechanism includes two groups of slave gears, the ends of the slave gears are rotatably connected to the outer ring of the valve body, a guide roller is arranged between the two groups of slave gears, a main gear and a synchronous toothed belt are arranged directly above the guide roller, the synchronous toothed belt is coiled between the guide roller, the main gear and the slave gear, the main gear and the slave gear are meshed with the synchronous toothed belt, the slave gear is fixedly sleeved on the end of the screw, the ends of the guide roller and the main gear are rotatably connected to the outer ring of the valve body, and a pressure sensor is arranged on the end of the main head shell; The inner frame together with the pressure-bearing column moves along the inner cavity of the outer frame toward the sealing port, so that the parallel distance between the pressure-bearing column and the inverted slope becomes smaller. In this way, when the pressure-bearing column squeezes the inverted slope, the feed amount of the valve head toward the sealing port will increase, so that the extrusion pressure on the sealing gasket will become larger until the external Fengming alarm no longer sounds, thereby realizing the adjustment of the valve head feed amount and increasing the service life of the sealing gasket.

[0010] The beneficial effects of the present invention are as follows: 1. The switch inside the valve body is driven by a cylinder to improve the automation rate of the device. Secondly, two sets of ventilation chambers are arranged in the device, and the two sets of ventilation chambers can independently cut off and restore the gas flow, thereby integrating the function of controlling the gas in and out of the thermal storage type organic waste gas oxidation furnace, improving the diversity of the device functions, and making the device more practical.

[0011] 2. The rotating rocker arm drives the fan-shaped plate to rotate, and the fan-shaped plate drives the pin shaft to squeeze the two sets of second rectangular grooves on one end of the T-type pressure block, so that the T-type pressure block moves along the movable groove toward the pressure column. As the T-type pressure block moves, the inverted slope on the other end of the T-type pressure block will squeeze the pressure column. Since the position of the pressure column is fixed, the inverted slope will be squeezed by the pressure column, so that the T-type pressure block drives the main head shell together with the sealing gasket to continue to squeeze the sealing port until the two sets of rocker arms are respectively blocked by the two sets of limit plates and cannot continue to rotate, thereby realizing the above-mentioned sealing of the sealing port. Due to the angle between the spring and the rocker arm, even if the movable rod loses the push of the cylinder, under the action of the spring elastic force, the two sets of rocker arms will fit tightly against the two sets of limit plates, so that the other end of the T-type pressure block cannot be retracted into the movable groove, ensuring that in the event of a cylinder failure, the entire valve head still maintains a good seal against the sealing port, thereby preventing untreated organic waste gas from leaking to the outside.

[0012] 3. When the sealing gasket is worn, the extrusion pressure on the pressure sensor on the end of the main head shell will inevitably decrease, and the pressure sensor controls the external buzzer alarm to sound. At this time, the staff uses a hexagonal wrench to rotate the main gear, and the main gear drives the synchronous belt to make a circular motion around the guide roller, the main gear, and the slave gear. At the same time, the synchronous belt drives the two sets of slave gears to rotate, and the slave gear drives the screw to rotate, so that the inner frame together with the pressure-bearing column moves along the inner cavity of the outer frame toward the sealing port, making the parallel distance between the pressure-bearing column and the inverted slope smaller. In this way, when the pressure-bearing column squeezes the inverted slope, the feed amount of the valve head toward the sealing port will increase. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0024] like Figures 1 to 3As shown, a lateral bench press sealing valve described in an embodiment of the present invention includes a valve body 1, two groups of ventilation chambers 2 are symmetrically arranged between the outer ring and the inner ring of the valve body 1, a sealing port 3 is opened on one side of the ventilation chamber 2, two groups of docking ports 4 are symmetrically arranged at one end of the valve body 1, the two groups of docking ports 4 are respectively connected to the two groups of ventilation chambers 2, a switch mechanism 5 is arranged in the ventilation chamber 2, the switch mechanism 5 includes a movable rod 501, two groups of guide holes 101 are symmetrically opened on the outer ring of the valve body 1, the movable rod 501 is movably inserted into the guide holes 101, a valve head 502 fixedly connected to one end of the movable rod 501, the valve head 502 is located in the ventilation chamber 2, a sealing gasket 503 fixedly mounted on the valve head 502, the valve head 502 is opposite to the sealing port 3, a cylinder 504, the other end of the movable rod 501 is connected to the piston rod of the cylinder 504, the cylinder 504 is fixedly installed on the support seat 505, and one end of the support seat 505 is fixedly connected to the outer ring of the valve body 1.

[0025] Specifically, the sealing gasket 503 is a rubber gasket with good elasticity. One group of docking ports 4 is connected to the organic waste gas storage device through a conduit, and the other group of docking ports 4 is connected to the outside world through a conduit. In the initial state, the two groups of valve heads 502 are separated from the two groups of blocking ports 3. When the organic waste gas needs to be treated, the switch mechanism 5 in the other group of ventilation chambers 2 is started, and the cylinder 504 pushes the movable rod 501 together with the valve head 502 to move toward the blocking port 3, so that the end of the valve head 502 is inserted into the blocking port 3, and the sealing gasket 503 is close to the edge of the blocking port 3 to achieve the blocking of the blocking port 3, and then the waste gas storage device injects the organic waste gas into a group of docking ports 4 through a conduit, and then the waste gas enters a group of ventilation chambers 2 through a group of docking ports 4, and the waste gas enters the inner cavity of the valve body 1 through the blocking port 3 in the ventilation chamber 2, and the waste gas flows along the inner cavity of the valve body 1 After entering the thermal storage type organic waste gas oxidizer, after the thermal storage type organic waste gas oxidizer has finished processing the waste gas entering, according to the same operation as above, the switch mechanism 5 in one group of ventilation chambers 2 blocks the corresponding blocking port 3, and then the switch mechanism 5 in the other group of ventilation chambers 2 releases the blocking of the blocking port 3, and the treated waste gas in the thermal storage type organic waste gas oxidizer is discharged through the other group of ventilation chambers 2, so as to realize the control of the gas in and out of the thermal storage type organic waste gas oxidizer. Compared with the prior art, the switch inside the valve body 1 is driven by the cylinder 504 to improve the automation rate of the device. Secondly, two groups of ventilation chambers 2 are arranged in the device, and the two groups of ventilation chambers 2 can independently realize the cutting off and restoring of gas flow, thereby integrating the function of controlling the gas in and out of the thermal storage type organic waste gas oxidizer, improving the diversity of the device function, and making the device more practical.

[0026] Furthermore, a docking joint 5041 is threadedly connected to the end of the piston rod of the cylinder 504 , and a docking groove 5011 for engaging with the docking joint 5041 is formed at the other end of the movable rod 501 .

[0027] Specifically, the cylinder 504 is connected to the movable rod 501 by engaging the docking head 5041 with the docking groove 5011 . The cooperation between the docking head 5041 and the docking groove 5011 facilitates the installation and removal of the cylinder 504 and the movable rod 501 .

[0028] like Figures 4 to 6 As shown, the valve head 502 includes a main head shell 5021, a sealing gasket 503 fixedly sleeved on the main head shell 5021, one end of the movable rod 501 is plugged into the main head shell 5021, two groups of rocker arms 5022 are cross-arranged in the main head shell 5021, a sector plate 5023 fixedly connected to one end of the rocker arm 5022, a rotary shaft 5024 rotatably connected to one end of the rocker arm 5022, the rotary shaft 5024 is fixedly installed in the main head shell 5021, the sector plate 5023 is plugged into a T-shaped pressure block 5025, two groups of springs 5026 symmetrically distributed in the main head shell 5021, one end of the spring 5026 is connected to the rocker arm 5022, and the other end of the spring 5026 is connected to the inner wall of the main head shell 5021, and two groups of limit plates 5027 are symmetrically fixedly installed in the main head shell 5021, and the limit plates 5027 are used Regarding the blocking rocker arm 5022, a first rectangular groove 221 is provided on both groups of the rocker arms 5022, a receiving shaft 5012 is provided in the other end of the movable rod 501, and the receiving shaft 5012 passes through the two groups of first rectangular grooves 221, and two groups of movable grooves 211 are symmetrically provided on the outer ring of the main head shell 5021, and the T-shaped pressure block 5025 is movably inserted into the movable groove 211, and second rectangular grooves 251 are provided on both sides of one end of the T-shaped pressure block 5025, and a pin shaft 231 is provided on the fan-shaped plate 5023, and both ends of the pin shaft 231 are respectively located in the two groups of second rectangular grooves 251, and two groups of brackets 6 are symmetrically provided on both sides of the main head shell 5021, and the bracket 6 is fixedly installed in the ventilation cavity 2, and a pressure column 7 is rotatably installed in one end of the bracket 6, and an inverted inclined surface 252 for squeezing the pressure column 7 is provided on the other end of the T-shaped pressure block 5025.

[0029] Specifically, the sealing of the plugging port 3 by the valve head 502 needs to be pushed by the cylinder 504. The cylinder 504 is prone to malfunction after long-term use, which will gradually weaken the pushing force of the cylinder 504 on the valve head 502. When the thermal storage type organic waste gas oxidation furnace is treating waste gas, high temperature will be generated inside the oxidation furnace, resulting in a high air pressure inside the oxidation furnace. Once the pushing force of the cylinder 504 on the valve head 502 is reduced, the air pressure inside the oxidation furnace will push open the valve head 502, causing the organic waste gas to be discharged in advance, causing the external environment to be polluted by the organic waste gas. Therefore, in the process of the valve head 502 blocking the plugging port 3, the movable rod 501 is squeezed by the receiving shaft 5012. The groove walls of the two groups of first rectangular grooves 221 cannot rotate because the swing rod 5022 is restricted by the spring 5026, and the entire valve head 502 will move toward the blocking port 3. When the end of the main head shell 5021 is inserted into the blocking port 3 and the sealing gasket 503 is attached to the edge of the blocking port 3, the main head shell 5021 cannot move further, and the inverted slopes 252 on the other ends of the two groups of T-shaped pressure blocks 5025 are respectively facing the two groups of pressure-bearing columns 7. Then the extrusion force of the groove walls of the two groups of first rectangular grooves 221 by the receiving shaft 5012 will cause the two groups of swing rods 5022 to rotate, and the swing rods 5022 stretch the springs 5026. The rotation direction of the two groups of swing rods 5022 is downward. Figure 6 The two groups of arrows indicate the directions. The rotating swing rod 5022 drives the fan-shaped plate 5023 to rotate. The fan-shaped plate 5023 drives the pin shaft 231 to squeeze the two groups of second rectangular grooves 251 on one end of the T-shaped pressure block 5025, so that the T-shaped pressure block 5025 moves along the movable groove 211 toward the pressure column 7. As the T-shaped pressure block 5025 moves, the inverted slope 252 on the other end of the T-shaped pressure block 5025 will squeeze the pressure column 7. Since the position of the pressure column 7 is fixed, the inverted slope 252 will be squeezed by the pressure column 7, so that the T-shaped pressure block 5025 drives the main head shell 5021 together with the sealing gasket 503 to continue to squeeze the sealing port 3 until The two groups of rocker arms 5022 are respectively blocked by the two groups of limit plates 5027 and cannot continue to rotate, thereby achieving the above-mentioned sealing of the sealing port 3. Due to the angle between the spring 5026 and the rocker arm 5022, even if the movable rod 501 loses the push of the cylinder 504, under the action of the elastic force of the spring 5026, the two groups of rocker arms 5022 will fit tightly against the two groups of limit plates 5027, so that the other end of the T-shaped pressure block 5025 cannot be retracted into the movable groove 211, ensuring that in the event of a failure of the cylinder 504, the entire valve head 502 still maintains good sealing performance on the sealing port 3 to prevent untreated organic waste gas from leaking to the outside. Embodiment 2

[0030] like Figure 5 , Figure 7 , Figure 8 , Fig. 9As shown, in contrast to Example 1, another embodiment of the present invention is as follows: the bracket 6 includes an outer frame 601, one end of the outer frame 601 is fixedly connected to the valve body 1, an inner frame 602 is movably installed in the outer frame 601, a pressure column 7 is rotatably installed in one end of the inner frame 602, a screw 603 rotatably connected to the other end of the inner frame 602, the screw 603 is screwed to the outer frame 601, and two sets of linkage mechanisms 8 are symmetrically arranged on the outer ring of the valve body 1, and the linkage mechanism 8 includes two sets of slave gears 801, and the ends of the slave gears 801 are rotatably connected to the outer ring of the valve body 1. A guide roller 803 is arranged between the two groups of slave gears 801, a main gear 802 and a synchronous belt 804 are arranged directly above the guide roller 803, the synchronous belt 804 is coiled between the guide roller 803, the main gear 802 and the slave gear 801, the main gear 802 and the slave gear 801 are both meshed with the synchronous belt 804, the slave gear 801 is fixedly mounted on the end of the screw 603, the ends of the guide roller 803 and the main gear 802 are both rotatably connected to the outer ring of the valve body 1, and a pressure sensor 212 is arranged on the end of the main head shell 5021.

[0031] Specifically, after long-term use, the sealing gasket 503 will be worn, resulting in the thickness of the sealing gasket 503 becoming thinner. Since the pressure-bearing column 7 squeezes the inverted slope 252 to make the feed amount of the valve head 502 toward the sealing port 3 fixed, once the sealing gasket 503 is worn, the sealing performance of the valve head 502 to the sealing port 3 will be weakened, resulting in a shorter service life of the sealing gasket 503. Therefore, when the sealing gasket 503 is worn, the pressure sensor 212 on the end of the main head shell 5021 is inevitably subjected to a reduced extrusion force, and the pressure sensor 212 controls the external buzzer alarm to sound. At this time, the staff rotates the main gear 802 with a hexagonal wrench, and the main gear 802 drives the synchronous gear The belt 804 makes a circular motion around the guide roller 803, the main gear 802 and the slave gear 801. At the same time, the synchronous toothed belt 804 drives the two sets of slave gears 801 to rotate, and the slave gear 801 drives the screw 603 to rotate, so that the inner frame 602 and the pressure-bearing column 7 move along the inner cavity of the outer frame 601 toward the sealing port 3, so that the parallel distance between the pressure-bearing column 7 and the inverted slope 252 becomes smaller. In this way, when the pressure-bearing column 7 squeezes the inverted slope 252, the feed amount of the valve head 502 toward the sealing port 3 will increase, so that the extrusion pressure on the sealing gasket 503 becomes larger until the external buzzer alarm no longer sounds, thereby realizing the adjustment of the feed amount of the valve head 502 and improving the service life of the sealing gasket 503.

[0032] Working principle: start the switch mechanism 5 in another ventilation chamber 2, the cylinder 504 pushes the movable rod 501 together with the valve head 502 to move toward the blocking port 3, so that the end of the valve head 502 is inserted into the blocking port 3, and the sealing gasket 503 is close to the edge of the blocking port 3 to achieve the blocking of the blocking port 3, and then the waste gas storage device injects the organic waste gas into a group of docking ports 4 through the conduit, and then the waste gas enters a group of ventilation chambers 2 through a group of docking ports 4, and the waste gas enters through the blocking port 3 in the ventilation chamber 2. The exhaust gas enters the inner cavity of the valve body 1, and the exhaust gas enters the thermal storage type organic exhaust gas oxidation furnace along the inner cavity of the valve body 1. After the thermal storage type organic exhaust gas oxidation furnace has finished processing the exhaust gas entering, the same operation as above is performed to make the switch mechanism 5 in one set of ventilation chambers 2 block the corresponding blocking port 3, and then make the switch mechanism 5 in another set of ventilation chambers 2 release the blocking port 3, and the treated exhaust gas in the thermal storage type organic exhaust gas oxidation furnace is discharged through the other set of ventilation chambers 2, thereby realizing the control of the gas inlet and outlet of the thermal storage type organic exhaust gas oxidation furnace; When the valve head 502 blocks the sealing port 3, the movable rod 501 squeezes the groove walls of the two groups of first rectangular grooves 221 through the receiving shaft 5012. Since the swing rod 5022 is restricted by the spring 5026 and cannot rotate, the entire valve head 502 will move toward the sealing port 3. When the end of the main head shell 5021 is inserted into the sealing port 3 and the sealing gasket 503 is attached to the edge of the sealing port 3, the main head shell 5021 cannot move further, and the inverted slopes 252 on the other ends of the two groups of T-shaped pressure blocks 5025 are respectively facing the two groups of pressure-bearing columns 7. Then the squeezing force of the groove walls of the two groups of first rectangular grooves 221 by the receiving shaft 5012 will cause the two groups of swing rods 5022 to rotate, and the swing rods 5022 stretch the spring 5026. The rotation direction of the two groups of swing rods 5022 is downward. Figure 6 The two groups of arrows indicate the directions. The rotating swing rod 5022 drives the fan-shaped plate 5023 to rotate. The fan-shaped plate 5023 drives the pin 231 to squeeze the two groups of second rectangular grooves 251 on one end of the T-shaped pressure block 5025, so that the T-shaped pressure block 5025 moves along the movable groove 211 toward the pressure column 7. As the T-shaped pressure block 5025 moves, the inverted slope 252 on the other end of the T-shaped pressure block 5025 squeezes the pressure column 7. Since the pressure column 7 is fixed, the inverted slope 252 is squeezed by the pressure column 7, so that the T-shaped pressure block 5025 drives the main head shell 5021 together with the sealing gasket 503 to continue to squeeze the blocking port 3, until the two groups of swing rods 5022 are respectively blocked by the two groups of limit plates 5027 and cannot continue to rotate, thereby achieving the above-mentioned sealing of the blocking port 3; When the sealing gasket 503 is worn, the extrusion pressure on the pressure sensor 212 at the end of the main head shell 5021 will inevitably decrease, and the pressure sensor 212 controls the external buzzer alarm to sound. At this time, the staff uses a hexagonal wrench to rotate the main gear 802, and the main gear 802 drives the synchronous toothed belt 804 to make a circular motion around the guide roller 803, the main gear 802, and the slave gear 801. At the same time, the synchronous toothed belt 804 drives the two sets of slave gears 801 to rotate, and the slave gear 801 drives the screw 603 to rotate, so that the inner frame 602 together with the pressure-bearing column 7 moves along the inner cavity of the outer frame 601 toward the sealing port 3, so that the parallel distance between the pressure-bearing column 7 and the inverted slope 252 becomes smaller, so that when the pressure-bearing column 7 squeezes the inverted slope 252, the feed amount of the valve head 502 toward the sealing port 3 will increase.

[0033] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
