Description

Technical Field

[0001] This utility model relates to the field of surge control technology, and in particular to an electrically controlled surge valve. Background Technology

[0002] When an exhaust gas engine with a turbocharger throttle valve operates under high pressure ratio conditions, a large back pressure and airflow fluctuation will be generated between the turbocharger and the engine intake port when the throttle valve is suddenly closed or its opening is drastically reduced. The intake pipe will vibrate violently, and the compressor impeller will be subjected to a counter-impact. The intake pipe and compressor impeller will emit a sharp and piercing whistling sound. This phenomenon is professionally known as "surge".

[0003] To prevent turbocharger bearing failure caused by repeated surge, a turbocharger surge valve is often installed in the engine intake control system. During rapid engine deceleration, the high-pressure gas after boosting is released to the atmosphere or before boosting, which reduces the pressure of the boosted gas and prevents turbocharger surge, effectively protecting the turbocharger and extending its lifespan.

[0004] Currently, the structure of common turbocharger anti-surge valves on the market is complex. The high-pressure gas at the intake port is prone to generating dynamic pressure, which causes fluctuations in the valve core opening process. In addition, the exhaust noise is too loud, which reduces the service life of the turbocharger anti-surge valve. Utility Model Content

[0005] This application discloses an electronically controlled surge valve to solve the problems in the prior art where high-pressure gas at the inlet easily generates dynamic pressure, causing fluctuations in the valve core opening process and excessive exhaust noise.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] An electrically controlled surge valve, comprising:

[0008] Valve cover;

[0009] The valve body is connected to the valve cover. An air inlet is provided on the side of the valve body away from the valve cover, and an air outlet is provided on the side wall of the valve body.

[0010] The valve core is slidably disposed inside the valve cover and is used to connect or disconnect the air inlet and air outlet.

[0011] The electromagnet assembly is located inside the valve cover. The valve core is connected to the electromagnet assembly. The electromagnet assembly is used to drive the valve core to move so that the valve core connects or disconnects the air inlet and outlet.

[0012] The silencer ring is connected to the side of the valve core facing the air inlet. The silencer ring is used to prevent the high-pressure gas at the air inlet from generating dynamic pressure that causes fluctuations in the valve core opening process.

[0013] The silencer sleeve is fitted outside the valve core and is located inside the valve body. The silencer sleeve is used to disperse airflow energy and reduce exhaust noise.

[0014] The technical solution adopted in this utility model can achieve the following beneficial effects:

[0015] This invention uses an electromagnet assembly to drive the valve core, allowing it to connect or disconnect the air inlet and outlet. During rapid engine deceleration, the electromagnet assembly connects the air inlet and outlet, opening the valve. High-pressure gas enters the valve body through the inlet and exits through the outlet. A muffler ring prevents the high-pressure gas at the inlet from generating dynamic pressure that could cause fluctuations during valve core opening. A muffler sleeve disperses airflow energy, reducing exhaust noise and preventing turbocharger and intake manifold surge, thus extending the service life of the turbocharger anti-surge valve. This invention features a simple structure, easy disassembly and installation, low manufacturing and maintenance costs, and high flexibility. Attached Figure Description

[0030] The utility model concept of this application is described here:

[0031] The following is in conjunction with the appendix Figure 1 The present application provides a detailed description of an electrically controlled surge valve through specific embodiments and application scenarios.

[0032] Reference Figure 1 An electrically controlled surge valve includes: a valve cover 100, a valve body 200, a valve core 300, an electromagnet assembly 400, a silencing ring 500, and a silencing sleeve 600.

[0033] The valve body 200 is connected to the valve cover 100. An air inlet 210 is provided on the side of the valve body 200 away from the valve cover 100, and an air outlet 220 is provided on the side wall of the valve body 200.

[0034] Specifically, the valve cover 100 is installed above the valve body 200; a second sealing ring 20 is used to achieve static sealing at the joint between the valve body 200 and the valve cover 100; the valve cover 100 is fixedly connected to the valve body 200 by hexagonal bolts 40, and the number of hexagonal bolts 40 is 4-6 to ensure the stability of the connection between the valve cover 100 and the valve body 200.

[0035] The valve core 300 is slidably disposed inside the valve cover 100, and the valve core 300 is used to connect or disconnect the air inlet 210 and the air outlet 220.

[0036] Specifically, the valve core 300 can be sealed with the air inlet 210. When the valve core 300 is in contact with the air inlet 210, the air inlet 210 and the air outlet 220 are disconnected; when the valve core 300 is separated from the air inlet 210, the air inlet 210 and the air outlet 220 are connected.

[0037] Reference Figure 1 The electromagnet assembly 400 is located inside the valve cover 100. The valve core 300 is connected to the electromagnet assembly 400. The electromagnet assembly 400 is used to drive the valve core 300 to move so that the valve core 300 connects or disconnects the air inlet 210 and the air outlet 220.

[0038] The silencer ring 500 is connected to the side of the valve core 300 facing the air inlet 210. The silencer ring 500 is used to prevent the high pressure gas in the air inlet 210 from generating dynamic pressure and causing fluctuations in the opening process of the valve core 300.

[0039] Specifically, the valve core 300, the silencer ring 500, and the electromagnet assembly 400 are assembled and connected together by fastening screws 50. When the electromagnet assembly 400 drives the valve core 300 to move, it can also drive the silencer ring 500 to move. The specific structure and working principle of the silencer ring 500 are conventional technologies known to those skilled in the art, and will not be described in detail here.

[0040] The silencer sleeve 600 is fitted outside the valve core 300 and inside the valve body 200. The silencer sleeve 600 is used to disperse airflow energy and reduce exhaust noise.

[0041] Specifically, the silencer sleeve 600 is connected to the bottom of the valve cover 100; the silencer sleeve 600 separates the air inlet 210 and the air outlet 220. When the valve core 300 is separated from the air inlet 210, the gas enters the valve body 200 from the air inlet 210 and is discharged from the air outlet 220 through the holes on the silencer sleeve 600. The specific structure and working principle of the silencer sleeve 600 are conventional technologies known to those skilled in the art, and will not be described in detail here.

[0042] Reference Figure 1 In this embodiment, the valve cover 100, valve body 200, valve core 300, electromagnet assembly 400, silencer ring 500 and silencer sleeve 600 are ensured to be coaxially assembled.

[0043] Specifically, the sealing performance of the overall structure is ensured by coaxially assembling the valve cover 100, valve body 200, valve core 300, electromagnet assembly 400, silencer ring 500 and silencer sleeve 600.

[0044] Reference Figure 1 In this embodiment, the valve core 300 includes, from bottom to top, an abutment 310, a recessed part 320, and a hollow cylinder 330;

[0045] The abutment 310 is sealed to the air inlet 210, the hollow cylinder 330 is slidably fitted to the valve cover 100, the electromagnet assembly 400 is connected to the abutment 310, and the muffler ring 500 is connected to the side of the abutment 310 facing the air inlet 210.

[0046] Specifically, the abutment 310, the recessed part 320 and the hollow cylinder 330 are integrally formed, which makes the manufacturing simple and the structure robust. The bottom of the abutment 310 is provided with a central recess, which is used to reduce the compression ratio of the Lorentz supercharger and extend the service life of the valve core 300.

[0047] Reference Figure 1 In this embodiment, the diameter of the recessed part 320 is smaller than the diameter of the hollow cylinder 330.

[0048] Specifically, by setting the diameter of the recessed part 320 to be smaller than the diameter of the hollow cylinder 330, it is easier for high-pressure gas to enter the valve body 200 and then be discharged.

[0049] Reference Figure 1 In this embodiment, the electromagnet assembly 400 includes a coil 410, a moving iron core 420, and a spring 430;

[0050] The coil 410 is installed inside the valve cover 100. One end of the moving iron core 420 is slidably connected inside the coil 410. The other end of the moving iron core 420 passes through the hollow cylinder 330 and the concave part 320 in sequence and is connected to the abutment part 310. A spring 430 is sleeved on the moving iron core 420. The spring 430 connects the coil 410 and the end of the moving iron core 420 near the abutment part 310.

[0051] Specifically, the electromagnet assembly 400 also includes a housing, which is installed inside the valve cover 100. A coil 410 is installed inside the housing. One end of the moving iron core 420 is slidably connected inside the coil 410, and the other end of the moving iron core 420 passes sequentially through the housing, the hollow cylinder 330, and the recessed part 320, and is connected to the abutment part 310. The valve core 300, the silencer ring 500, and the moving iron core 420 are assembled and connected together using fastening screws 50. The hollow cylinder 330... The 0 is fitted outside the outer shell, and the hollow cylinder 330 slides with the outer shell; the abutment 310, the concave part 320, the hollow cylinder 330, the outer shell, the coil 410, the moving iron core 420 and the spring 430 are ensured to be coaxially assembled; the abutment 310, the concave part 320 and the hollow cylinder 330 are all provided with inner cavities, and the moving iron core 420 and the valve core 300 are provided with axial and radial clearances to ensure that the two are self-centered and do not over-position and jam.

[0052] Reference Figure 1In this embodiment, a limit block 421 is installed on one end of the moving iron core 420 near the abutment 310, and a spring 430 connects the coil 410 and the limit block 421.

[0053] Specifically, the limiting block 421 is located in the inner cavity of the concave part 320, and there is a certain distance between the limiting block 421 and the concave part 320. The two ends of the spring 430 are connected to the outer shell and the limiting block 421 respectively, so that after the power is cut off, the spring 430 pushes the valve core 300 to reset, thereby disconnecting the air inlet 210 and the air outlet 220.

[0054] Reference Figure 1 In this embodiment, a valve seat 700 connected to the valve body 200 is installed inside the air inlet 210, and a valve port gasket 710 that seals with the abutment member 310 is installed on the valve seat 700.

[0055] Specifically, the valve seat 700 and the valve body 200 are press-fitted together, and the joint is sealed with a first sealing ring 10. The valve port gasket 710 is installed on the valve seat 700 after vulcanization treatment to ensure that the abutment 310 sits on the valve port gasket 710, which not only seals the valve port but also provides a buffering effect when the valve core 300 is reset, as the abutment 310 contacts the valve port gasket 710.

[0056] Reference Figure 1 In this embodiment, the abutment 310 is provided with a ventilation balance hole 340 that allows the air inlet 210 to communicate with the inner cavity of the concave part 320.

[0057] Specifically, there is a certain gap between the muffler ring 500 and the abutment 310. This allows the air inlet 210 to communicate with the inside of the valve core 300, so that the pressure of the air inlet 210 enters the inner cavity of the valve core 300 to eliminate the pressure difference between the upper and lower ends of the valve core 300.

[0058] Reference Figure 1 In this embodiment, the air inlet 210 and air outlet 220 of the valve body 200 are both provided with flange connection structures, which is conducive to the conversion of pipeline diameter and flexible layout. In addition, the end face is provided with a sealing groove to ensure the robustness and sealing performance of the anti-surge valve.

[0059] Reference Figure 1 In this embodiment, the valve cover 100 is provided with a connector 800 for controlling the electromagnet assembly 400.

[0060] Specifically, the valve cover 100 and the connector 800 can be locked together with four screws, and a third sealing ring 30 is provided between them to ensure a seal. The connector 800 can be oriented in four directions (front, back, left, right) as needed, which makes the installation and use of the product more flexible and conducive to the layout planning of the user. The connector 800 can also press and position the housing of the electromagnet assembly 400. In this embodiment, the connector 800 is a plug interface containing metal pins and electronic components. It is used to receive the PWM signal (which can also be understood as power) from the engine control unit to control the movement of the moving iron core 420 of the electromagnet assembly 400. The moving iron core 420 drives the valve core 300 and the muffler ring 500 to move upward, connecting the air inlet 210 and the air outlet 220 to realize the venting function. After the power is cut off, the spring 430 pushes the valve core 300 to reset, so that the air inlet 210 and the air outlet 220 are disconnected.

[0061] In summary, during actual use, when the engine decelerates rapidly, the PWM signal received by the connector 800 is used to control the movement of the moving iron core 420 of the electromagnet assembly 400. The moving iron core 420 drives the valve core 300 and the muffler ring 500 to move upward, connecting the intake port 210 and the exhaust port 220. The valve opens, and high-pressure gas enters the valve body 200 from the intake port 210, then enters the valve body 200, and exits from the exhaust port 220 through the holes on the muffler sleeve 600. The muffler ring 500 prevents the high-pressure gas in the intake port 210 from generating dynamic pressure that causes fluctuations in the opening process of the valve core 300. The muffler sleeve 600 disperses the airflow energy, reduces exhaust noise, and improves the service life of the turbocharger anti-surge valve.

[0062] This invention is an electrically controlled surge valve. It controls the opening and closing of the valve by receiving PWM signals. The opening and closing times are both digitally controllable. Furthermore, this invention has undergone computer fluid simulation analysis and calculation to optimize airflow direction and noise vibration.
