Description

Technical Field

[0001] This utility model relates to the field of exchange valve technology, and in particular to an exchange valve that can reduce the detonation of coke oven gas. Background Technology

[0002] In the coke oven heating system, the exchange valve is one of the most important heating devices. It is the essential passage for coke oven gas, responsible not only for supplying coke oven gas to the rising side vertical flue, but also for decarbonizing the descending side vertical flue. At the same time, the regular exchange operation ensures the stable heating of the coke oven body.

[0003] A related technology, Chinese patent CN217683346U, provides a gas exchange cock, which includes a housing with a gas outlet, a gas inlet, and a waste gas outlet, and consists of four main parts: a gas guide pipe, a core, and an exchange handle. The core is located inside the housing and has a descending gas outlet, an ascending gas outlet / descending waste gas outlet, and an ascending gas inlet. All of these are connected to a tapered horizontal inner cavity within the core. A drive shaft is mounted on the small end of the core, and the exchange handle is mounted on the drive shaft. When the coke oven gas is in an ascending gas flow, the ascending gas inlet and the ascending gas outlet / descending waste gas outlet are connected to the gas pipeline, and the coke oven gas heats the coke oven through the cock. When the coke oven gas is in a descending gas flow, the ascending gas inlet is sealed by the housing.

[0004] In the process of developing this application, the inventors discovered that the technology has at least the following problems: after the core and the shell rotate relative to each other multiple times, wear will occur between the core and the shell. Even when the exchange valve is in the closed state, air leakage will still occur, which will require the exchange valve to be replaced. Utility Model Content

[0005] In order to extend the service life of the exchange cock, this application provides an exchange cock that can reduce the detonation of coke oven gas.

[0006] The exchange valve provided in this application, which can reduce the detonation of coke oven gas, adopts the following technical solution:

[0007] An exchange valve for reducing the detonation of coke oven gas includes a housing with a gas inlet, a gas outlet, and an exhaust gas outlet. A drive end plate and an adjustment end plate are rotatably disposed within the housing. A set of cores is slidably disposed between the drive end plate and the adjustment end plate, forming an airflow channel between the opposing surfaces of the cores. The opposing surfaces of the cores are designed to fit against the inner wall of the housing. An adjustment assembly is jointly disposed on the cores and the adjustment end plate, and the adjustment assembly is used to cause relative movement of the cores.

[0008] By adopting the above technical solution, the core body is in close contact with the inner wall of the shell, making it difficult for gas inside the shell to flow between the core body and the inner wall of the shell. An airflow channel is formed between the opposite faces of the core body, allowing gas inside the shell to flow through the airflow channel. When the gas inlet and gas outlet are connected, the exchange handle drives the drive end plate to rotate, and the drive end plate drives the core body to rotate, thus rotating the airflow channel between the core bodies to connect the gas inlet and gas outlet. At this time, the core body blocks the exhaust gas outlet. When the gas inlet and gas outlet are cut off, the exchange handle drives the drive end plate to rotate, and the drive end plate drives the core body to rotate, causing the core body to block the gas inlet and gas outlet. When wear occurs between the core body and the shell, gas inside the shell may flow between the opposite faces of the core body and the inner wall of the shell. At this time, the core body is moved by adjusting the component, so that the opposite faces of the core body are once again in close contact with the inner wall of the shell, making the exchange cock less prone to leakage, thereby extending the service life of the exchange cock.

[0009] Preferably, a drive shaft is fixedly mounted on the end of the drive end plate away from the core.

[0010] By adopting the above technical solution, the exchange handle is connected to the drive end plate through the drive shaft, and then the exchange handle controls the opening and closing of the exchange cock.

[0011] Preferably, the core includes a left end plate, a right end plate, and a side plate. The left end plate is slidably connected to the drive end plate, and the right end plate is slidably connected to the adjustment end plate. The left end plate and the right end plate are arranged opposite to each other. One end of the side plate is fixedly connected to the left end plate, and the other end of the side plate is fixedly connected to the right end plate. The airflow channel is located between the opposite faces of the side plates, and the opposite sides of the side plates are used to abut against the inner wall of the shell.

[0012] By adopting the above technical solution, when the core of the adjustment component moves, the drive end plate and the housing are kept relatively stationary by the exchange handle. Then, the adjustment component drives the left end plate to move along the drive end plate, and the adjustment component drives the right end plate to move along the adjustment end plate. When the exchange valve is controlled to open or close, the drive end plate and the housing are rotated relative to each other by the exchange handle. The drive end plate drives the left end plate to rotate, the left end plate drives the side plate to rotate, the side plate drives the right end plate to rotate, the right end plate drives the adjustment end plate to rotate, and the adjustment end plate drives the adjustment component to rotate.

[0013] Preferably, the drive end plate has a set of left guide grooves symmetrically opened on the side facing the adjustment end plate, and a left guide block is slidably arranged in the left guide groove. The outer wall of the left guide block is in contact with the inner wall of the left guide groove. One of the left guide blocks is fixedly connected to one of the left end plates, and the other left guide block is fixedly connected to the other left end plate.

[0014] By adopting the above technical solution, the left end plate moves along the left guide groove on the drive end plate via the left guide block.

[0015] Preferably, the adjusting end plate has a set of right guide grooves symmetrically opened on the side facing the driving end plate, and a right guide block is slidably arranged in the right guide groove. The outer wall of the right guide block is in contact with the inner wall of the right guide groove. One of the right guide blocks is fixedly connected to one of the right end plates, and the other right guide block is fixedly connected to the other right end plate.

[0016] By adopting the above technical solution, the right end plate moves along the right guide groove on the adjusting end plate via the right guide block.

[0017] Preferably, a left insertion block is fixedly provided on one of the left end plates, and a left slot is provided on the other left end plate for the insertion of the left insertion block; a right insertion block is fixedly provided on one of the right end plates, and a right slot is provided on the other right end plate for the insertion of the right insertion block.

[0018] By adopting the above technical solution, the left end plate, which is set opposite to the left end plate, is connected to the left slot through the left insert block, and the right end plate, which is set opposite to the left end plate, is connected to the right slot through the right insert block.

[0019] Preferably, the adjustment assembly includes an adjustment shaft, a left gear, a right gear, a left rack, and a right rack. One end of the adjustment shaft is rotatably connected to the drive end plate, and the other end of the adjustment shaft passes through the adjustment end plate. The left gear and the right gear are both sleeved on the adjustment shaft and are fixedly connected to the adjustment shaft. The left rack is fixedly mounted on the left insert block, and the left slot is for inserting the left rack. The left rack meshes with the left gear. The right rack is fixedly mounted on the right insert block, and the right slot is for inserting the right rack. The right rack meshes with the right gear.

[0020] By adopting the above technical solution, the rotation of the adjusting shaft drives the left gear and the right gear to rotate. The rotation of the left gear drives the left rack to move. The movement of the left rack causes the left end plate to move relative to the left. The rotation of the right gear drives the right rack to move. The movement of the right rack causes the right end plate to move relative to the right, thereby achieving the effect of relative movement of the core.

[0021] Preferably, a mounting plate is fixedly installed on the end of the adjusting shaft away from the drive end plate, and a plurality of mounting screws are provided on the mounting plate. A mounting bracket is fixedly installed on the outer wall of the housing, and a mounting through hole is opened on the mounting bracket. The mounting screws are inserted into the mounting through hole, and a mounting nut is threadedly connected to the mounting screw. The mounting nut is used to abut against the mounting bracket.

[0022] By adopting the above technical solution, the adjusting shaft and the housing are connected by a mounting screw and a mounting nut.

[0023] Preferably, a connecting screw is fixedly provided between the adjusting shaft and the mounting plate, and a locking seat is threadedly connected to the connecting screw. The locking seat has several locking holes, and a locking groove is provided on the adjusting end plate. A locking screw is provided in both the locking groove and the locking holes. A set of locking nuts is threadedly connected to the locking screw, and the opposite face of the locking nuts is used to abut against the locking seat.

[0024] By adopting the above technical solution, when the core moves relative to the locking nut, the locking nut is rotated to separate from the locking seat, and then the locking screw is moved out of the locking groove. At this time, the adjusting shaft and the adjusting end plate rotate relative to each other. When the core is kept relatively stationary, the locking seat is rotated first to align the locking hole on the locking seat with the locking groove on the adjusting end plate. Then the locking screw is inserted into the locking groove, and then the locking nut is rotated to make the locking nut abut against the locking seat, thereby fixing the adjusting shaft and the adjusting end plate.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By setting up a shell, gas inlet, gas outlet, exhaust outlet, drive end plate, adjustment end plate, core, airflow channel and adjustment components, the exchange cock is less prone to leakage, thereby extending the service life of the exchange cock;

[0035] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0036] This application discloses an exchange valve that can reduce the detonation of coke oven gas. (See also...) Figures 1 to 4 The system includes a housing 1, with a gas inlet 11, a gas outlet 12, and an exhaust gas outlet 13. A drive end plate 2 is rotatably mounted inside the housing 1. A drive shaft 21 is mounted on the end of the drive end plate 2 furthest from the adjustment end plate 3, and the drive shaft 21 is connected to an exchange plate. A set of cores 4 are slidably disposed between the drive end plate 2 and the adjustment end plate 3, forming an airflow channel 431 between the opposing surfaces of the cores 4, allowing gas inside the housing 1 to flow through the airflow channel 431. The opposing surfaces of the cores 4 are designed to fit against the inner wall of the housing 1, preventing gas from easily flowing between the opposing surfaces of the cores 4 and the inner wall of the housing 1. An adjustment assembly 5 is jointly provided on the cores 4 and the adjustment end plate 3, and the adjustment assembly 5 is used to allow relative movement of the cores 4. When the gas inlet 11 and gas outlet 12 are connected, the exchange handle drives the drive end plate 2 to rotate, which in turn drives the core 4 to rotate. This causes the airflow channel 431 between the cores 4 to rotate and connect the gas inlet 11 and gas outlet 12, at which point the core 4 blocks the exhaust gas outlet 13. When the gas inlet 11 and gas outlet 12 are disconnected, the exchange handle drives the drive end plate 2 to rotate, which in turn drives the core 4 to rotate, causing the core 4 to block the gas inlet 11 and gas outlet 12. When wear occurs between the core 4 and the housing 1, gas inside the housing 1 may leak between the back of the core 4 and the inner wall of the housing 1. At this time, the adjustment component 5 moves the core 4, pressing the back of the core 4 tightly against the inner wall of the housing 1 again, preventing leakage from the exchange cock and extending its service life.

[0037] Reference Figures 1 to 4The core 4 includes a left end plate 41, a right end plate 42, and a side plate 43. The left end plate 41 and the right end plate 42 are arranged opposite each other. One end of the side plate 43 is welded to the left end plate 41, and the other end of the side plate 43 is welded to the right end plate 42. The airflow channel 431 is located between the opposite faces of the side plates 43, and the side plates 43 are arranged opposite each other to abut against the inner wall of the housing 1. A set of left guide grooves 412 are symmetrically opened on the side of the drive end plate 2 facing the adjustment end plate 3. A left guide block 411 is slidably arranged in the left guide groove 412, and the outer wall of the left guide block 411 is in contact with the inner wall of the left guide groove 412. One left guide block 411 is welded to one of the left end plates 41, and the other left guide block 411 is welded to the other left end plate 41. The left end plate 41 moves along the left guide groove 412 on the drive end plate 2 through the left guide block 411. A set of right guide grooves 422 are symmetrically formed on the side of the adjusting end plate 3 facing the driving end plate 2. A right guide block 421 is slidably disposed in the right guide groove 422, and the outer wall of the right guide block 421 is in contact with the inner wall of the right guide groove 422. One right guide block 421 is welded to one of the right end plates 42, and the other right guide block 421 is welded to the other right end plate 42. The right end plate 42 moves along the right guide groove 422 on the adjusting end plate 3 through the right guide block 421. When the adjusting component 5 drives the core 4 to move, the driving end plate 2 and the housing 1 are kept relatively stationary by exchanging the handle. Then, the adjusting component 5 drives the left end plate 41 to move along the driving end plate 2, and the adjusting component 5 drives the right end plate 42 to move along the adjusting end plate 3. When the switching valve is turned on or off, the switching handle causes the drive end plate 2 to rotate relative to the housing 1. The drive end plate 2 drives the left end plate 41 to rotate, the left end plate 41 drives the side plate 43 to rotate, the side plate 43 drives the right end plate 42 to rotate, the right end plate 42 drives the adjusting end plate 3 to rotate, and the adjusting end plate 3 drives the adjusting assembly 5 to rotate.

[0038] In order to make the core 4 move relative to each other, refer to Figures 1 to 4The adjusting assembly 5 includes an adjusting shaft 51, a left gear 52, a right gear 53, a left rack 54, and a right rack 55. One end of the adjusting shaft 51 is rotatably connected to the drive end plate 2, and the other end of the adjusting shaft 51 passes through the adjusting end plate 3. The left gear 52 and the right gear 53 are both sleeved on the adjusting shaft 51 and are welded to the adjusting shaft 51. A left insert block 541 is installed on one left end plate 41, and the left rack 54 is installed on the left insert block 541. A left slot 542 is opened on the other left end plate 41 for the left insert block 541 and the left rack 54 to be inserted. A right insert block 551 is installed on one right end plate 42, and the right rack 55 is installed on the right insert block 551. A right slot 552 is opened on the other right end plate 42 for the right insert block 551 and the left rack 54 to be inserted. The left rack 54 meshes with the left gear 52, and the right rack 55 meshes with the right gear 53. The rotation of the adjusting shaft 51 drives the left gear 52 and the right gear 53 to rotate. The rotation of the left gear 52 drives the left rack 54 to move. The movement of the left rack 54 causes the left end plate 41 to move relative to it. The rotation of the right gear 53 drives the right rack 55 to move. The movement of the right rack 55 causes the right end plate 42 to move relative to it, thereby achieving the effect of relative movement of the core 4.

[0039] Reference Figures 1 to 5 A connecting screw 7 is welded to the end of the adjusting shaft 51 away from the drive end plate 2. A mounting plate 62 is welded to the side of the connecting screw 7 away from the adjusting shaft 51. Several mounting screws 6 are installed on the mounting plate 62 facing the adjusting end plate 3. A mounting bracket 63 is installed on the outer wall of the housing 1. A mounting through hole 64 is opened on the mounting bracket 63, and the mounting screw 6 is inserted into the mounting through hole 64. A mounting nut 61 is threaded onto the mounting screw 6, and the mounting nut 61 abuts against the mounting bracket 63. A locking seat 71 is threaded onto the connecting screw 7. Several locking holes 72 are opened on the locking seat 71, and several locking grooves 73 are opened on the adjusting end plate 3. Locking screws 74 are inserted into the locking grooves 73 and locking holes 72. A set of locking nuts 75 are threaded onto the locking screw 74, and the opposite surfaces of the locking nuts 75 are used to abut against the locking seat 71. When the core 4 moves relative to the locking nut 75, rotate the locking nut 75 to separate it from the locking seat 71, and then move the locking screw 74 out of the locking groove 73. At this time, the adjusting shaft 51 and the adjusting end plate 3 rotate relative to each other. When the core 4 is kept relatively stationary, first rotate the locking seat 71 to align the locking hole 72 on the locking seat 71 with the locking groove 73 on the adjusting end plate 3, then insert the locking screw 74 into the locking groove 73, and then rotate the locking nut 75 to abut against the locking seat 71, thereby fixing the adjusting shaft 51 and the adjusting end plate 3.

[0040] The implementation principle of the exchange valve that can reduce the explosion of coke oven gas in this application embodiment is as follows: When the gas inlet 11 and the gas outlet 12 are connected, the exchange handle drives the drive end plate 2 to rotate, and the drive end plate 2 drives the core 4 to rotate, thereby rotating the airflow channel 431 between the cores 4 to connect the gas inlet 11 and the gas outlet 12. At this time, the core 4 blocks the exhaust gas outlet 13. When the gas inlet 11 and the gas outlet 12 are cut off, the exchange handle drives the drive end plate 2 to rotate, and the drive end plate 2 drives the core 4 to rotate, so that the core 4 blocks the gas inlet 11 and the gas outlet 12. When wear occurs between the core 4 and the shell 1, the gas in the shell 1 will flow between the opposite side of the core 4 and the inner wall of the shell 1. At this time, the adjustment shaft 51 is rotated, and the adjustment shaft 51 drives the left gear 52 and the right gear 53 to rotate, so that the core 4 moves to the opposite side of the core 4 and is once again in close contact with the inner wall of the shell 1. When the back of the core 4 phases is tightly attached to the inner wall of the housing 1, the gas inside the housing 1 is less likely to flow between the back of the core 4 phases and the inner wall of the housing 1, thus extending the service life of the exchange valve.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
