In order to ensure the safety operation of gas fired boiler,we should make sure that its safety valve has no failures,but the actual condition is often not satisfied,so the boiler users need to know the following failures that may occur on the gas fired boiler safety valve to do good protection preparation.
Gas fired boiler safety valve leak
Under the normal working pressure,the medium leakage more than allowed level occurs in the sealing surface of safety valve disc and seat,the continuous leak will lead to the hard sealing material destruction.
Gas fired boiler safety valve frequent jump
The low pressure of gas fired boiler safety valve back seat is of great harm to the operation of the boiler,it will cause the timeout emissions of a lot of medium,resulting in unnecessary energy loss.
Gas fired boiler safety valve chattering
The dithering phenomenon occurring in the emission process of safety valve is called safety valve chattering,it can easily cause metal fatigue,decrease the mechanical properties of the relief valve,causing serious hidden trouble of equipment,so we need to take measures to deal with that.
The above failures that may occur on the gas fired boiler safety valve,ZG gas fired boilers have various protective functions of over-temperature,over-pressure,water shortage,leak,flameout,etc,which ensures the safe and reliable operation,pleasure feel free to contact us for more details!
