Simply put, whatever is currently in the line between the valve is installed on, can only flow in one way through the valve. That's why it is important to change plastic pipe fittings for air check valves every so often. Plastic pipe fittings are also susceptible to air flow blockage.<br><br><br>A common problem with a plastic air check valve is when the one outlet hose gets plugged with a different piping system than what is in your air control panel. In other words, you may have one hose that is for a different pressure than the others. This can often cause your valve to either not completely close or not close all the way. If this happens, you should replace both the hoses.<br><br><br>Another problem with some air check valves is when two adjoining valves try to seal each other. They will typically engage with each other and both will let the flow pass but the outlet hose won't close. This can cause your flow to be limited in certain areas or prevent the valve from closing entirely.<br><br><br>Plastic pipe fittings for air check valves can also be broken due to misuse. For instance, non-return valves are designed so that when the "retracted" setting is selected, it will shut off the valve and disconnect it from the pressure source. However, many people end up trying to turn the valve back on without resetting it first. When the valve does start operating again, it may not close all the way, leaving you with a partial flow. The non-return valve also needs to be connected to a certain pressure source in order for it to work properly and allow the valve to return to its closed position. If you have a plastic pipe fitting that has broken, you need to either repair or replace it.<br><br><br>Rotary Screw Air Check Valves have been a common problem among compressors. The rotary screw in these types of check valves has been known to cause quite a bit of problems. Sometimes the screws will become stripped or melted. Other times the entire rotation of the screw will come undone resulting in the air flow stopping altogether. These types of non-return valves are usually very difficult to repair and will require a new compressor in order to work properly again.<br><br><br>Clogged Gaskets This is another one of the main problems with non-return air check valves. In order to open them, you must first turn the "on" side up and then rotate the "off" side. With a dirty, clogged gasket, this is much more difficult to do, resulting in less flow back into the air compressor. If you cannot remove the dirt, you must replace your gasket before you can solve the problem. The best way to do this is to look at replacing the gasket with a new one.<br><br><br>Damaged Valve - The most common reason why a valve doesn't open or close is because of the damper being damaged. A damper is the rubber ring on the inlet side of the valve. If you loved this article and you would like to acquire more facts about [https://www.shunchengvalve.com/ simply click the next website page] kindly take a look at the web-page. If it has become completely cracked, it will prevent the valve from closing or opening. The only way to repair this type of valve is to remove the old one and cut off the new ring. You should also make sure there aren't any cracks on the new ring, as this could cause damage to the new valve and cause the flow to stop altogether.<br><br><br>Positive Pressure Level Sensors: When the air flows past a check valve, it causes a small pump action that pushes the "pumping" end of the valve outward. This movement pushes the rubber band against the piston so that it snaps shut when the pressure reaches a certain point. These pressure sensitive discs are located on either side of the disc in the air flow path. They sense the direction of the flow by detecting the change in airflow. If the direction of the flow is going in the wrong direction, the disc won't close.<br>
