Composite High Speed Exhaust Valve CARX-10Q/16Q

The composite high-speed exhaust valve is used at high points or places with closed air in the pipeline to expel the gas inside the pipeline and clear it, achieving normal operation. If no exhaust valve is installed, the liquid flowing in the pipeline will generate dynamic heat to cause gas, forming a section, and making the water output of the pipeline meet the design requirements. Secondly, when the pipeline experiences power outage or pump shutdown during operation, negative pressure will cause pipeline vibration or rupture, The exhaust valve quickly draws air into the pipe to prevent pipeline vibration or rupture. When the air is completely discharged, water enters the valve and floats the ball, causing the transmission plug to close and stopping the exhaust. When the pipeline is running normally, a small amount of gas will naturally accumulate in the upper part of the pipeline. To a certain extent, the water level inside the valve will drop, and the float ball will drop at any time. The gas will be discharged from the small hole. If there is a power outage, pump shutdown, and empty water flow in the pipeline, negative pressure may occur at any time in the pipeline. The floating ball will descend along the water, and the small hole will be opened to drive the large hole for a large amount of air intake to ensure the safety of the pipeline. Working principle: When water enters the pipeline, the plug stops at the upper part of the fixed float ball for a large amount of exhaust. When the air is exhausted, the water flows into the valve to float the ball, and the transmission plug is closed to stop exhaust. During normal operation of the pipeline, a small amount of gas will naturally be produced, which will all accumulate in the upper part of the pipeline. To a considerable extent, the water level inside the valve will drop, and the floating ball will lower along the water. The gas will be discharged from the small hole. If there is a power outage or pump shutdown, negative pressure may occur at any time when the water flow in the pipeline is empty. The floating ball will descend along the water and open the small hole to drive the large hole for a large amount of air intake to ensure the safety of the pipeline. Note: During use, the pressure should not be lower than 0.03MPa. If the pressure is lower than 0.03MPa, the exhaust valve is prone to water leakage and must be equipped with a valve for maintenance. Technical parameters: 1)Medium: Clear water 2)Temperature: Room temperature 3)Valve body: ductile iron QT450 4)Float and plug: stainless steel 5)Sealing material: nitrile rubber 6)Valve body test pressure: 1.5mpa 7)Float and sealing test pressure: 0.05-1.1MPA without water leakage Installation requirements: 1)Before installation, please check and remove any debris inside the main body. 2)Install a gate valve in front of the valve for future installation and maintenance. If the valve is installed in a shaded well, there should be sufficient space to accommodate technical personnel for adjustment and maintenance work. 3)If the new composite exhaust valve is installed outdoors, please pay attention to the insulation of the valve to prevent the water inside the valve from freezing or cracking the valve. 4)If the pipeline where the exhaust valve is located frequently experiences water supply interruption, it is recommended to install a buffer valve in front of the exhaust valve. Selection of installation location: The installation position of the exhaust valve directly affects the exhaust effect and the operation status of the pipeline.Designers often limit themselves to local high points during design, and there are multiple installation positions for exhaust valves. Only by comprehensively considering the entire pipeline can the exhaust effect be optimal. The common installation locations for new composite exhaust valves include local high points, points where the downward slope increases, points where the upward slope decreases, and long distance non folding upward or downward pipe sections.
