Valve storage and maintenance
The purpose of storage and maintenance is to prevent the valve from being damaged or reduced in quality during storage. In fact, improper storage is one of the important reasons for valve damage.
2, valve storage, should be in good order, large valves can be neatly arranged on the ground in the warehouse, can not be randomly stacked, do not let the flange connection surface contact the ground.
3. Due to improper storage and handling, the handwheel is broken, the valve stem is crooked, the fixed nut of the handwheel and the valve stem is loose and lost, etc.
4. The valve processing surface that can rust in the atmosphere should be coated with anti-rust oil to protect it.
5. The valve placed outdoors must be covered with rainproof and dustproof articles such as linoleum or tarpaulin. Store the valve warehouse to keep clean and dry.
Maintenance of valve packing
1, packing is directly related to the valve switch when the leakage of the key seals, if the packing failure, resulting in leakage, the valve is equal to failure. Enhanced maintenance can extend the life of the filler.
2. After the valve is installed in the pipeline, due to factors such as temperature, extravasation may occur. At this time, the nuts on both sides of the packing gland must be tightened in time.
