Description
Technical Field
[0001] This utility model relates to the field of turbine housing technology, and in particular to a turbine housing structure. Background Technology
[0002] The turbine housing is an important component of a turbocharger. It is made of high-temperature and corrosion-resistant alloy materials. Its main function is to contain and guide the exhaust gas so that it can effectively drive the turbine to rotate. The turbine housing has a specific shape and flow channel design to optimize the flow characteristics of the exhaust gas and improve the efficiency of the turbine.
[0003] A search revealed Chinese Patent Publication No. CN217841757U, which discloses a turbocharger and its housing structure, relating to the field of engine turbocharger technology. The aforementioned housing structure includes a turbine housing, which includes an intake chamber for radial air intake and a rotor chamber connected to the intake chamber. The rear end of the rotor chamber is connected to an exhaust chamber for axial air exhaust. A bypass channel is provided between the intake chamber and the exhaust chamber, bypassing the rotor chamber and connecting the intake chamber and the exhaust chamber. The aforementioned turbocharger housing structure optimizes the original exhaust gas discharge structure and adds a bypass channel, which can reduce the axial load on the turbine rotor under high exhaust resistance conditions, extend service life, reduce noise pollution, and better meet the increasingly demanding requirements of engines, further improving the safety of turbocharger use. In contrast, the existing turbine housing structure delivers exhaust gas to the turbine rotor through the main exhaust pipe, thereby driving the turbine rotor to rotate. When the engine enters a high exhaust resistance condition, the exhaust gas pressure inside the turbine housing rises rapidly, resulting in excessive load on the turbine rotor. Utility Model Content
[0004] To overcome the above deficiencies, this utility model provides a turbine housing structure, which aims to improve the problem in the prior art where the exhaust gas pressure inside the turbine housing rises rapidly when the engine enters a high exhaust resistance condition, resulting in excessive turbine rotor load.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a turbine housing structure, including a turbine housing, an intake pipe connected to the left side of the turbine housing, an exhaust port opened on the front side of the turbine housing, a bypass channel connected to the bottom right side of the turbine housing, an intelligent valve connected to the front end of the bypass channel, a controller fixedly connected to the right side of the intelligent valve, a pressure sensor fixedly connected to the inner wall of the intake pipe, and a convenient cleaning mechanism installed on the rear side of the turbine housing, the convenient cleaning mechanism facilitating the cleaning of the turbine housing structure.
[0006] The above technical solution involves discharging exhaust gas through the exhaust port. At this time, a pressure sensor fixed in the intake pipe detects the pressure. When the exhaust gas pressure reaches a predetermined value, the pressure sensor sends a signal to the controller. When the controller receives the signal from the pressure sensor, it controls the intelligent valve to open. Thus, through the cooperation of the intelligent valve and the bypass channel, some of the exhaust gas in the turbine housing is discharged before it reaches the turbine rotor, thereby relieving the exhaust gas pressure in the turbine housing when the engine enters a high exhaust resistance condition.

The left sides of the insert buckles are fixedly connected with springs. The left middle of the insert buckles is fixedly connected with steel wires. The ends of the steel wires are fixedly connected with pull rings.
[0009] The above technical solution involves: multiple pull rings driving corresponding steel wires forward, thereby pulling the corresponding buckles back into the fixing buckles; then pulling the back cover to remove it and clean the inside of the turbine housing structure; after cleaning the inside of the turbine housing structure, aligning the fixing groove on the back cover with the fixing buckle; then pushing the back cover to make the fixing groove on it engage with the corresponding fixing buckle; and then releasing the multiple pull rings to allow multiple springs to push the corresponding buckles to engage and fix the back cover.
[0010] As a further description of the above technical solution:
[0011] A mounting bracket is fixedly connected to the front end of the inner wall of the intelligent valve, and a filter screen is fixedly connected to the outer wall of the mounting bracket.

[0013] As a further description of the above technical solution:
[0014] The inner wall of the rear cover is equidistantly connected to multiple rotating rods, and the outer walls of the multiple rotating rods are all fixedly connected to pulleys.
[0015] The above technical solution improves the smoothness of wire pulling by fixing the pulley with a rotating rod.
[0016] As a further description of the above technical solution:
[0017] Each of the pull rings has a rubber sleeve fixedly connected to its outer wall, and each of the rubber sleeves has anti-slip texture on its outer wall.
[0018] The above technical solution improves grip by using anti-slip textures on the rubber sleeve fixed to the outside of the pull ring.
[0019] As a further description of the above technical solution:
[0020] A fixing ring is fixedly connected to the top of the air intake pipe, and a threaded hole is provided at each of the four corners of the outer wall of the fixing ring.
[0021] The above technical solution involves a retaining ring fixed on the intake pipe that connects to external equipment via a threaded hole.
[0022] As a further description of the above technical solution:
[0023] The controller has screws threaded to both the front and back sides of its top, and display pieces are threaded to the outer walls of both screws.
[0024] The above technical solution allows for the display of detailed information about the turbine housing structure on a display panel fixed to the controller with screws.
[0025] As a further description of the above technical solution:
[0026] A mounting ring is fixedly connected to the rear side of the rear cover, and two threaded holes are equally spaced on the outer wall of the mounting ring.
[0027] Through the above technical solution, the turbine housing structure is installed by a mounting ring fixed to the rear cover and threaded holes.
[0028] This utility model has the following beneficial effects:
[0029] 1. In this utility model, a pressure sensor fixed inside the intake pipe detects the pressure. When the exhaust gas pressure reaches a predetermined value, the pressure sensor sends a signal to the controller. Subsequently, the controller controls the intelligent valve to open. Thus, through the cooperation of the intelligent valve and the bypass channel, some of the exhaust gas in the turbine housing is discharged before it reaches the turbine rotor, thereby achieving the effect of relieving the exhaust gas pressure in the turbine housing when the engine enters a high exhaust resistance condition.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0039] Reference Figure 2 and Figure 3This utility model provides an embodiment of a turbine housing structure, including a turbine housing 1. An intake pipe 3 is connected to the left side of the turbine housing 1. An exhaust port 4 is opened on the front side of the turbine housing 1. Exhaust gas entering through the intake pipe 3 is discharged through the exhaust port 4. A bypass channel 5 is connected to the bottom right side of the turbine housing 1. A smart valve 6 is connected to the front end of the bypass channel 5. The smart valve 6 is used to control the opening and closing of the bypass channel 5. A controller 7 is fixedly connected to the right side of the smart valve 6. The controller 7 is used to control the smart valve 6. A pressure sensor 8 is fixedly connected to the inner wall of the intake pipe 3. The pressure sensor 8 is used to measure the pressure inside the turbine housing. A convenient cleaning mechanism 2 is installed on the rear side of the turbine housing 1. The convenient cleaning mechanism 2 facilitates cleaning the turbine housing structure. A fixing frame 9 is fixedly connected to the front end of the inner wall of the smart valve 6. A filter screen 10 is fixedly connected to the outer wall of the fixing frame 9. The fixing frame 9 fixed inside the smart valve 6 is used to fix the filter screen 10.
[0040] Specifically, the exhaust gas is discharged through the exhaust port 4. At this time, the pressure sensor 8 fixed in the intake pipe 3 detects the pressure. When the exhaust gas pressure reaches the predetermined value, the pressure sensor 8 sends a signal to the controller 7. When the controller 7 receives the signal from the pressure sensor 8, it controls the intelligent valve 6 to open. Thus, through the cooperation of the intelligent valve 6 and the bypass channel 5, some of the exhaust gas in the turbine housing 1 is discharged before it reaches the turbine rotor. This relieves the exhaust gas pressure in the turbine housing 1 when the engine enters a high exhaust resistance condition. The filter screen 10 fixed in the intelligent valve 6 by the mounting bracket 9 can prevent foreign objects from entering the intelligent valve 6.
[0041] Reference Figure 4 and Figure 5 The convenient cleaning mechanism 2 includes a rear cover 201. The front side of the rear cover 201 is installed on the rear side of the volute housing 1. Fixing buckles 202 are fixedly connected to all four sides of the outer wall of the volute housing 1. The fixing buckles 202 are used to fix the rear cover 201. A snap fastener 203 is slidably connected to the rear right side of each of the multiple fixing buckles 202. The snap fastener 203 is used to engage the rear cover 201. A spring 204 is fixedly connected to the left side of each of the multiple snap fasteners 203. The spring 204 is used to correspond to the snap fastener 203. The middle left side of each of the multiple snap fasteners 203 is fixed. A steel wire 205 is connected, and a pull ring 206 is fixedly connected to the end of each steel wire 205. The pull ring 206 pulls the buckle 203 through the steel wire 205. A plurality of rotating rods 11 are equidistantly rotatably connected to the inner wall of the back cover 201. A pulley 12 is fixedly connected to the outer wall of each of the multiple rotating rods 11. The rotating rods 11 are used to fix the pulleys 12. A rubber sleeve 13 is fixedly connected to the outer wall of each of the multiple pull rings 206. Anti-slip texture 14 is opened on the outer wall of each of the multiple rubber sleeves 13. The anti-slip texture 14 is used to improve the anti-slip performance of the rubber sleeve 13.
[0042] Specifically, multiple pull rings 206 drive the corresponding steel wires 205 forward, thereby pulling the corresponding buckles 203 back into the fixing buckles 202. Then, pull the back cover 201 to remove it and clean the inside of the turbine housing structure. After cleaning the inside of the turbine housing structure, align the fixing groove on the back cover 201 with the fixing buckle 202, then push the back cover 201 so that the fixing groove on it engages with the corresponding fixing buckle 202. Then, release the multiple pull rings 206 so that multiple springs 204 push the corresponding buckles 203 to engage and fix the back cover 201. The pulley 12 fixed by the rotating rod 11 can improve the smoothness of pulling the steel wires 205. The rubber sleeve 13 fixed outside the pull rings 206 improves its grip with the anti-slip texture 14.
[0043] Reference Figure 1 , Figure 3 and Figure 4 A fixing ring 15 is fixedly connected to the top of the intake pipe 3. Threaded holes 16 are provided at the four corners of the outer wall of the fixing ring 15. The intake pipe 3 is fixed to the equipment through the fixing ring 15 and the threaded holes 16 thereon. Screws 17 are threadedly connected to the front and rear sides of the top of the controller 7. Display pieces 18 are threadedly connected to the outer walls of the two screws 17. The screws 17 are used to fix the display pieces 18. An installation ring 19 is fixedly connected to the rear side of the rear cover 201. Threaded holes 20 are provided at equal intervals on the outer wall of the installation ring 19. The turbine housing structure is installed through the installation ring 19 and the threaded holes 20 thereon.
[0044] Specifically, the retaining ring 15 fixed on the intake pipe 3 is connected to the external equipment through the threaded hole 16 opened on it. The display piece 18 fixed on the controller 7 by screws 17 displays detailed information about the turbine housing structure. The turbine housing structure is installed by the mounting ring 19 fixed behind the rear cover 201 and the threaded hole 20 opened on it.
[0045] Working principle: When the engine enters a high exhaust resistance condition, the exhaust gas pressure in the turbine housing rises rapidly, thereby driving the turbine rotor to rotate at high speed and expelling the exhaust gas through the exhaust port 4. At this time, the pressure sensor 8 fixed in the intake pipe 3 detects the pressure. When the exhaust gas pressure reaches a predetermined value, the pressure sensor 8 sends a signal to the controller 7. When the controller 7 receives the signal from the pressure sensor 8, it controls the intelligent valve 6 to open. Thus, through the cooperation of the intelligent valve 6 and the bypass channel 5, some of the exhaust gas in the turbine housing 1 is discharged before it reaches the turbine rotor, thereby achieving the effect of relieving the exhaust gas pressure in the turbine housing 1 when the engine enters a high exhaust resistance condition.
[0046] When the turbine housing structure needs cleaning, first pull the corresponding pull ring 206 behind each fixing buckle 202 on the turbine housing 1. This will cause the corresponding steel wire 205 to move forward through the multiple pull rings 206. In this way, the multiple steel wires 205 will pull the corresponding buckle 203 back into the fixing buckle 202. Then pull the rear cover 201 to remove the rear cover 201 and clean the inside of the turbine housing structure. After cleaning the inside of the turbine housing structure, align the fixing groove on the rear cover 201 with the fixing buckle 202. Then push the rear cover 201 so that the fixing groove on it engages with the corresponding fixing buckle 202. Then release the multiple pull rings 206 so that the multiple springs 204 push the corresponding buckle 203 to engage and fix it with the rear cover 201. This achieves the effect of convenient cleaning of the inside of the turbine housing structure.
[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
