Why does the automatic exhaust valve keep ringing after exhausting? It s like a bearing ringing

Insufficient exhaust can easily cause blowing.

Here are some of the well-known brands recognized in the valve industry, which are widely recognized and have a high reputation. While rankings may vary depending on time and market conditions, the following brands are generally considered to be among the top brands in the valve industry:

The following influential first-line brands of water system valves and industrial valves can be used as a reference, but for reference only: Suzhou Neway Valve, Shanghai Guanlong Valve, Shanghai Qizhong Valve, Sanhua, Su Yan, Shentong, Su Valve, Nanfang, Jiang.

First, the word Yao. The above manufacturers are only estimates and references, and the specific situation may vary or fluctuate at any time due to changes in a series of factors such as changes in the market, the size of the competition pattern, and the stability of product quality. As an indispensable key device in industrial production and civil facilities, the quality and reputation of the valve brand directly affect the satisfaction and trust of users.

These brands are known in the valve industry for their innovative technology, high-quality products and reliability. It is important to note that the market and industry are evolving rapidly, and different rankings may vary depending on time and region. For the most up-to-date ranking information, it is recommended to refer to industry reports, professional organizations or market research data for more detailed and accurate information.

Answer: It is normal for the exhaust valve in the middle and tail section to be closed and the sound tremor judgment.

The exhaust pipe of the car is equipped with a valve, and closing the valve is not the sound of the original car. The automobile exhaust pipe is installed in the exhaust pipe between the engine exhaust branch pipe and the muffler, so that the whole exhaust system is flexibly connected, so as to play the role of vibration and noise reduction, convenient installation and prolonging the life of the exhaust sound reduction system.

In fact, variable valve exhaust is not a very high-tech thing, most of the modified exhaust brands have this kind of product, in fact, it is equivalent to the combination of the advantages of the two exhausts described above, and install an adjustable valve in the pipeline, Li Dongwang let it according to the owner's intention or the speed of the engine, become quiet, take care of the low-torque back pressure exhaust, or the sound is excited, focusing on the high-speed performance of the straight-through exhaust.

The exhaust pipe sound is mainly due to the following reasons: 1. Ablation or poor sealing of individual exhaust valves; 2. Individual intake valve passwords are poor and serious air leakage; 3. There is carbon deposit on the joint surface of individual intake and exhaust valves and seat rings; 4. There is no gap between individual valve and foot pads and two idle holes of double-chamber carburetor are unevenly adjusted or one is blocked. Extended Content:

1. Automobile exhaust bellows, also known as automobile exhaust pipe hose, is installed in the exhaust pipe between the engine exhaust branch pipe and the muffler, so that the whole exhaust system is flexibly connected, so as to play the role of vibration and noise reduction, convenient installation and prolonging the life of the exhaust noise reduction system. 2. It is mainly used for light vehicles, mini cars and buses, and its structure is a double-layer bellows covered with steel wire mesh sleeve, and the structure of the jacket snap ring at both ends of the straight edge section, in order to make the sound reduction effect better, the bellows can be equipped with expansion joints or mesh sleeves.

Due to the exposed location of the exhaust pipe, problems are generally easy to find.

1.Step on the accelerator pedal, you will hear a banging sound coming out of the exhaust pipe, the sound may not be very loud, the car will not be abnormal when driving, fuel consumption will increase, and sometimes it will come out from the front of the similar sound.

Possible cause: It is recommended to check whether the muffler and exhaust pipe are damaged.

2.When driving at low speeds, or when the throttle is on the accelerator, there will be an abnormal noise under the engine, especially when the weather is relatively cool. It is recommended to raise the frame and check whether there is a heat shield between the exhaust pipe and the ground, which may be caused by the aging of the heat shield, and it can be solved by replacing or removing it.

3.There is an abnormal noise when turning or moving forward. The common squeak when cornering often comes from the driveshaft of the front wheel with a broken joint, and an intermittent crackling sound is heard.

Possible causes: It may be a hole in the exhaust pipe, or a sheet metal part or bumper that is partially detached.

It should be that the fixing parts are loose, and the noise from the vibration of the exhaust pipe after opening the car can be checked for specific noise and then reinforced.
