Should the Exhaust Valve Be Closed When Driving on the Highway?

[MacOscar]

It is best not to close it. The function of the exhaust valve is to control the exhaust sound and the size of the exhaust back pressure. More relevant information is as follows: 1. Introduction: The exhaust valve is an essential auxiliary component in pipeline systems, widely used at the highest points, elbows, or areas where air may be trapped in pipelines. It helps to remove gas from the pipeline to ensure smooth operation. Without this valve, the pipeline may experience air resistance at any time, preventing it from achieving the designed water capacity. Additionally, power outages during pipeline operation can cause vibrations or even ruptures. 2. Working Principle: During the exhaust state, the float, due to gravity, pulls one end of the lever downward, causing the lever to tilt. This creates a gap between the lever and the exhaust hole, allowing air to escape through this gap. As the air is expelled, the water level rises, and the buoyancy of the water causes the float to rise. The sealing end of the lever gradually presses against the exhaust hole until it is completely blocked.
