How to prevent the PP breathing valve from getting stuck
The PP breathing valve is a ventilation device fixed on the top of the storage tank to ensure the normal state of the pressure in the tank, prevent the tank from being damaged by overpressure or vacuum, and reduce the volatilization loss of the liquid in the tank. Not only can maintain the pressure balance of the storage tank, ensure that the storage tank is destroyed under overpressure or vacuum, and can reduce the medium and loss in the tank. The working principle is to use a spring limit valve plate, which is determined by positive and negative pressure or exhales or sucks. The breathing valve should have both positive and negative pressure relief functions. Specifically: when the container is under positive pressure, the breathing valve opens and the exhaled gas releases positive pressure; when the container is under negative pressure, the breathing valve opens and inhales the gas to release negative pressure . This ensures that the pressure is within a certain range and that the container is safe. One is to exhale or inhale when a certain pressure is reached, and the other is designed to purely not breathe, which can be understood as two two-way valves with appropriate pressure.
When the factory is in the process of installation, it may cause a lot of prestress for the irrational configuration of the PP breathing valve and the pipeline, or the cold compensation ability of the pipeline is poor. The valve position is changed, and now under low temperature conditions, deformation may occur. At that time, if the valve is improperly fixed, deformation may occur or the concentricity of the valve stem may be affected.
And now when we are in the process of using the PP breathing valve , in the process of low temperature, then bite the wire buckle, especially when we use a dark rod structure, then we can make the breathing valve a factory Service, but when the factory is in order to prevent the breathing valve from jamming, then the structure and screw can be used well, so that the breathing valve can work more stably in the factory, and in good condition, Can improve the efficiency of work.
However, when there are some faults in the PP breathing valve in the factory, it needs to be resolved in time before it can work again. Don't let it go. If it doesn't matter, it may be scrapped, and the work efficiency will be greatly reduced. And now when the breathing valve gets stuck in the early summer after cooling down, then we need to adjust the fixing of the cylinder shell in our factory, and then let the breathing valve open and close, so as to ensure the use of the breathing valve.
So now when we are using these breathing valves, we must regularly maintain the PP breathing valves . If there is a failure of the breathing valves, then we need to make timely repairs before we can let it Serve the factory.
