How to use pneumatic sanitary valve?
Pneumatic valve of health has a lot of, such as pneumatic diaphragm valve, pneumatic directional control valve, etc., they are all the standard electronic polishing, the surface is smooth, clean guaranteed, no medium accumulation zone, won't produce potential pollution, widely used in food, medicine, cosmetics, cleaning steam, liquor, beverages, biochemical industrial process control, etc. Attention should be paid to several key points in the use of pneumatic sanitary valves to ensure their proper operation.
The following points should be paid attention to when using pneumatic sanitary valve:
Pneumatic valve operators should clearly understand the role of each valve and its position in the processing pipeline to avoid wrong operation, which may cause accidents such as operation, mixing, pressure and so on.
The packing cap of the pneumatic sanitary valve should not be tightened so tightly that the pressure generated when the valve cannot be operated will cause friction or other vibration zones to be loosened.
When the valve is operating, it is not allowed to replace or add filler under normal conditions, otherwise there will be a risk of medium leakage.
In the low temperature season below 0℃, attention should be paid to prevent the stop valve from freezing. Open the bottom plug valve and discharge the frozen water in time. Valves that cannot be cleaned and continuously operated should be kept warm.
When the temperature rises above 200 ° c, bolt heating is prolonged, which can easily loosen the valve seal. At this point, the bolts should stop "hot tight" and should not stop at the valve's fully closed position to prevent the stem from pushing to the bottom, making it difficult to open again.
When the pneumatic sanitary valve leakage, the first to determine the location and cause of leakage.
There are two types of leakage: normal internal leakage and external leakage.
Internal leaks include leaks in high-pressure water systems. Various valve components can be intentionally lubricated. Lubrication protects seals, spools, or pistons from friction.
Another form of expected leakage keeps the pressure in the system at a safe level. External leakage is divided into packing leakage and cap leakage, body leakage and seal ring or liner leakage according to the external structure. Operators should identify exactly what kind of leak and then take immediate action.
