Description

Technical Field

[0001] The invention relates to the field of smoke exhaust channels, and in particular to an adjustable connecting rod valve for a smoke duct. Background Art

[0002] The smoke exhaust system is a huge safety facility that cannot be missing in engineering construction and installation. It plays an important role in air dredging, waste heat recovery, and preventing the spread of fire. The smoke exhaust valve is generally installed on the pipes of the mechanical smoke exhaust system and is the most important facility in the entire smoke exhaust system. In terms of preventing the spread of fire, when the gas temperature in the pipeline reaches 70°C, the smoke exhaust valve will automatically close, which plays a role in isolating smoke and blocking fire within a certain period of time, preventing the fire from spreading to other places through the ventilation pipeline, and can effectively prevent the spread of fire, and can meet the requirements of fire resistance stability and fire resistance integrity. In terms of waste heat recovery, it plays a role in controlling the opening and closing of the pipeline. However, because the smoke exhaust valve is installed in the middle of various pipelines and is usually invisible, many people ignore its role. Due to many unfavorable factors such as long-term stagnation and inconvenient maintenance, it is easy to cause the flexibility of the valve body to decrease in opening and closing, and some even fail completely, which becomes a hidden safety hazard. For valve bodies that undertake multi-pipeline unblocking, such as three-way valve bodies, single-threaded mechanical control was used in the past, that is, each output pipeline corresponds to a valve device. Once a problem occurs in this structure, one of the valve devices will be unusable, which makes the two-way use become one-way unblocking. The valve body lacks a linkage protection mechanism, which greatly reduces the functionality of the entire device. In addition, since they are all high-temperature flue gas unblocking, heat transfer is inevitable. The influence of high-temperature flue gas for a long time increases the heat of the entire valve body. If there are no effective measures and solutions, coupled with the thermal conductivity of metal, the heat will be transferred to the valve stem and valve handle, which can easily burn the operator and reduce the safety of the valve body.

The valve rod 12 penetrates through the valve body 1 and is fixedly connected.The heat insulation section 15 is located at the position of the valve stem sheath 16 on the side of the middle of the valve stem 12 close to the valve body 1. The heat insulation section 15 divides the valve stem 12 into two parts: the valve stem inside the valve body and the valve stem outside the valve body. The heat insulation section 15 is fixedly connected to the valve stem 12. The two valve plates 13 are respectively located on both sides of the valve stem inside the valve body of the valve stem 12. The two valve plates 13 are respectively fixedly connected to the valve stem 12.

The material of the heat insulation section 15 is Teflon or ceramic fiber. The number of the hinges 24 is 4, and all of them are spherical hinges.,

[0032] Working mode: The structure of the whole valve body 1 adopts an integrally formed metal part. This kind of metal part is more firm and durable than a welded part. The whole valve body 1 is fixedly installed between the smoke inlet pipe and the smoke outlet pipe of the flue. And the inside of the valve body 1 includes a smoke inlet chamber 2, a heat insulation chamber 3, a transverse smoke outlet chamber 7, a longitudinal smoke outlet chamber 9 and two regulating valves 11. Among them, the heat insulation chamber 3 is located at the top of the smoke inlet chamber 2 of the valve body 1. Heat-insulating cotton 4 is also provided inside the heat insulation chamber 3, and the heat insulation chamber 3 is filled with the heat-insulating cotton 4.

[0033] A flat steel flange 5 and three flanges 8 are also provided on the valve body 1. Among them, the flat steel flange 5 is installed at the top of the heat insulation chamber 3, and a handle 6 is provided at the top of the flat steel flange 5 for lifting the flat steel flange 5, so as to operate the inside of the heat insulation chamber 3. And the three flanges 8 are respectively located at the positions between the smoke inlet chamber 2 and the smoke inlet pipe, between the transverse smoke outlet chamber 7 and the smoke outlet pipe, and between the longitudinal smoke outlet chamber 9 and the smoke outlet pipe. These three flanges 8 respectively fixedly connect the smoke inlet chamber 2 and the smoke inlet pipe, the transverse smoke outlet chamber 7 and the smoke outlet pipe, and the longitudinal smoke outlet chamber 9 and the smoke outlet pipe. The flat steel flange 5 and each flange 8 use bolts to connect the valve body 1 with each flue gas passage, playing the role of a connecting link.

[0034] When high-temperature flue gas enters the valve body 1 from the inlet flue pipe, the high-temperature flue gas first enters the inlet flue chamber 2 of the valve body 1. The heat insulation chamber 3 is arranged at the top of the inlet flue chamber 2, and the heat insulation cotton 4 filled inside it plays a role in heat insulation for the high-temperature flue gas in the inlet flue chamber 2. In this way, a large amount of heat loss of the high-temperature flue gas can be prevented, providing good support for the transportation of the high-temperature flue gas. The operator can replace the heat insulation cotton 4 in the heat insulation chamber 3 irregularly by opening the flat steel flange 5 at the top of the heat insulation chamber 3, and the operation is simple; on one side of the inlet flue chamber 2 is the horizontal flue outlet chamber 7, and below the inlet flue chamber 2 is the vertical flue outlet chamber 9. Two regulating valves 11 are respectively located at the positions between the horizontal flue outlet chamber 7 and the inlet flue chamber 2, and between the vertical flue outlet chamber 9 and the inlet flue chamber 2;Each regulating valve 11 is composed of a valve stem 12, two valve plates 13, six valve plate reinforcing plates 14, a heat insulation section 15, a valve stem sheath 16, four valve stem reinforcing plates 17, a sealing pipe cap 18 and a flat key 20. The valve stem 12 runs through the entire valve body 1, and a heat insulation section 15 is provided in the middle of the valve stem 12. The heat insulation section 15 is located at the position with the valve stem sheath 16 on the side close to the valve body 1. The heat insulation section 15 divides the valve stem 12 into two parts: the valve stem inside the valve body and the valve stem outside the valve body. The valve stem outside the valve body is wrapped by the valve stem sheath 16, which can prevent the valve stem 12 outside the valve body 1 from being exposed, and plays a good protective effect on the valve stem outside the valve body of the valve stem 12. In addition, a sealing pipe cap 18 is provided at one end of the valve stem sheath 16 close to the valve handle 21, and a sealing rope 19 is provided inside the sealing pipe cap 18. The sealing rope 19 is used in cooperation with the sealing pipe cap 18 to fasten one end of the valve stem sheath 16 close to the valve handle 21 to the valve stem 12. The internal sealing rope 19 increases the friction coefficient between the sealing pipe cap 18 and the valve stem sheath 16, and then tightly fixes the sealing pipe cap 18 and the valve stem sheath 16 together. As the valve stem 12 rotates inside the valve stem sheath 16, it is easy to involve the valve stem sheath 16 outside the valve body 1 connected to it. Over time, the connection between the valve stem sheath 16 and the valve body 1 will become loose, resulting in the occurrence of the falling-off phenomenon. In order to consolidate the stability of the valve stem sheath 16, four valve stem reinforcing plates 17 are also provided on the side of the valve stem sheath 16. These four valve stem reinforcing plates 17 are distributed in a cross shape on the side of the valve stem sheath 16, and the end of each valve stem reinforcing plate 17 is fixed to fit the valve body 1, thereby playing a role of positioning and supporting the valve stem sheath 16. The valve stem 12 inside the valve body 1 is composed of a heat insulation section 15 and the valve stem inside the valve body. The two valve plates 13 are respectively located on both sides of the valve stem inside the valve body of the valve stem 12. Every two of the six valve plate reinforcing plates 14 are in a group, and are respectively parallel to both sides of the two valve plates 13. And the position of each valve plate reinforcing plate 14 with a central hole is used to splice and connect and fix the valve plates 13 on the left and right sides of the valve stem 12 with respect to the valve stem 12, thereby consolidating the valve plates 13 on the left and right sides of the valve stem 12 and preventing one of the valve plates 13 on either side of the valve stem 12 from falling off.;

[0035] In summary, each regulating valve 11 inside the valve body 1 is a gate used to open and close the high-temperature flue gas in the smoke inlet chamber 2 leading to the other two smoke outlet pipes. The valve stem 12 acts as a rotating shaft. Since the temperature of the flue gas in the valve body 1 is relatively high, its heat will be absorbed by the valve stem 12 made of metal. And due to the characteristics of heat transfer in metal, the valve stem 12 easily transfers the heat to the valve stem 12 outside the valve body 1. To prevent this phenomenon, an insulating section 15 is used in the middle of the valve stem 12 to divide it into two parts: the valve stem inside the valve body and the valve stem outside the valve body. The insulating section 15 is made of Teflon or ceramic fiber to block the outward transfer of heat, so that the temperature of the valve stem inside the valve body of the valve stem 12 remains at the heat of the high-temperature flue gas, while the temperature of the valve stem outside the valve body remains at room temperature. In this way, while avoiding heat loss, it can also protect the valve handle 21 and the angular actuator 22 outside the valve body 1, preventing excessive heat conduction and bringing many inconveniences to the operation of the operator, and improving the overall safety. When one regulating valve 11 is opened, the other regulating valve 11 will close. This alternating opening and closing operation mode can effectively control the effective transportation of high-temperature flue gas along different smoke exhaust pipes.

[0036] At the positions of the two valve handles 21 connected to the regulating valves 11 on the outside of the valve body 1 respectively, and at the position of the angular actuator 22 connected to the valve handle 21 close to the lateral smoke outlet chamber 7, the flat key 20 is located at one end of the regulating valve 11 close to the valve handle 21, and the flat key 20 is fixedly connected to the valve stem 12, thus strengthening the valve handle 21 connected to the valve stem 12. In addition, a valve handle connecting rod 23 is provided between the two valve handles 21. One end of the valve handle connecting rod 23 is fixedly connected to one end of one valve handle 21, and the other end of the valve handle connecting rod 23 is fixedly connected to one end of the other valve handle 21, so as to link the two valve handles 21 together to form a linkage mechanism. At the connection positions of the angular actuator 22 and the valve body 1, there are 4 spherical hinges 24 each, which can control the direction adjustment of the valve stems 12 connected respectively, making the rotation of the whole linkage device more flexible.

[0037] This device is an adjustable connecting rod valve installed between the smoke inlet pipe and the smoke outlet pipe of the flue. It has a clear structural idea, is convenient to use and operate. The structure fixed by flanges is convenient for installation and disassembly. By using the rotation of the linkage valve stem, it drives the rotation of the two valve plates connected to it, thereby controlling the opening size of the valve according to a certain proportion, and enabling the effective discharge of high-temperature flue gas along different smoke exhaust pipes. It has tight sealing, is safe and reliable, has smooth linkage, and is applicable to various large-scale smoke exhaust structure factories and spaces, as well as various equipment pipelines for preheating recovery.
