Product use: The working principle of the automatic exhaust valve: When the system is filled with water, the gas in the water continues to overflow and gather at the highest point due to changes in temperature and pressure. When the gas pressure is greater than the system pressure, the pontoon will fall and drive the valve stem to move downwards, the valve port is opened, and the gas is continuously discharged.When the gas pressure is lower than the system pressure, the float rises and drives the valve stem to move upward, and the valve port is closed.The automatic exhaust valve is constantly circulating in this way. |
1.When the automatic exhaust valve is installed, a globe valve must be installed! 2.When the pipeline is suppressed, the shut-off valve must be closed! 3.When installing the exhaust room, please try to install it in the kitchen or bathroom as much as possible. It is strictly prohibited to install it in the bedroom, living room or office. 4.Automatic exhaust valves are equipped with exhaust ports. The exhaust ports should be connected to the guide pipe. The guide pipe must be placed in a place where there is water or connected to a place where there is a sewer. 5.Part of the automatic exhaust valve series products are connected with copper joints. Please use raw material belts when installing. Do not use too much force during installation to avoid breaking the joints and water leakage accidents. 6.The automatic exhaust valve must be installed vertically, that is, it must ensure that the pontoon inside it is in a vertical state so as not to affect the exhaust.; 7.When the automatic exhaust valve is installed, it is best to install it together with the partition valve, so that when the exhaust valve needs to be removed for maintenance, the system can be kept closed and the water will not flow out.; 8.Automatic exhaust valves are generally installed in pipeline parts where the system is easy to collect air, such as the highest point of the system and the highest point of a section of pipeline, which is conducive to smooth exhaust. 9.The exhaust valve should be installed in the bathroom as much as possible, and it is not recommended to install it indoors.If it must be installed in the bedroom or living room, please add a backflow pipe to the exhaust valve and drain it outdoors.Prevent impurities from blocking the valve and cause valve drainage problems.It is also possible to drain water during the exhaust process, please note. If the installation is not carried out in accordance with the installation requirements, resulting in water leakage, we only provide paid services. |
