Installation and Setting of P11H-16P Automatic Exhaust Valve

The main function of an automatic exhaust valve is to eliminate the air inside the pipeline. Because water usually contains a certain amount of air, and the solubility of air decreases with increasing temperature, gas gradually separates from water during the circulation process and gradually gathers together to form large bubbles or even gas columns. Due to the replenishment of water, gas is often produced. P11H-16P automatic exhaust valve is generally used for pipeline exhaust in independent heating systems, centralized heating systems, heating boilers, central air conditioning, floor heating, and solar heating systems.

　　Installation of automatic exhaust valve:

Automatic exhaust valve is a device used to quickly remove gas from pipelines, improve the efficiency of water transportation equipment, and protect pipelines from deformation and rupture. It is a common equipment in pipelines. Installed at the outlet of the pump or in the water supply and distribution pipeline, this valve is used to remove a large amount of accumulated air from the pipeline, in order to improve the efficiency of the water pipe and pump. Once negative pressure occurs inside the pipeline, this valve can quickly suck in air to prevent damage to the pipeline caused by negative pressure.

When the water pump stops working, negative pressure will be generated at any time, and the floating ball will descend at any time to perform a large amount of suction to ensure the safety of the pipeline. When in the exhaust state, the float pulls down one end of the lever due to gravity, causing the lever to tilt and creating a gap at the contact area between the lever and the exhaust hole.

The air is discharged through this gap through the exhaust hole. As the air is discharged, the water level rises, and the float floats upward under the buoyancy of the water. The sealing end face on the lever gradually presses against the exhaust hole until the entire exhaust hole is blocked. At this point, the automatic exhaust valve is in a closed state.

　Setting of automatic exhaust valve:

1. The exhaust valve must be installed vertically, ensuring that the internal float is in a vertical position to avoid affecting the exhaust.

2. When installing the exhaust valve, it is best to install it together with the block valve, so that when the exhaust valve needs to be removed for maintenance, the system can be sealed and water will not flow out.

3. Exhaust valves are generally installed at the highest point of the system, which is beneficial for improving exhaust efficiency.
