How to maintain the valve

1. Keep the outside of the valve and moving parts clean

The surface of the valve, the trapezoidal thread on the valve stem and the valve stem nut, the sliding part of the valve stem nut and the bracket, and the gears, worm gears and worms are prone to deposit a lot of dirt, oil and medium residues, which will cause wear and corrosion to the valve. Therefore, the flushing valve and the bottom wire plug of the steam trap should be opened regularly for flushing, or should be removed and flushed regularly to avoid clogging the valve with dirt. The general dust on the valve can be swept with brush and compressed air, and even can be brushed with copper wire until the processed surface and mating surface show metallic luster, and the painted surface shows the natural color of paint.

2, keep the valve lubrication

The bearing position, the meshing parts of gears and worm gears and other cooperating movable parts all need good lubrication conditions to reduce mutual friction and avoid mutual wear. For parts that do not have an oil cup or nozzle and are easily damaged or lost during operation, Huaguang Valve manufacturer recommends that the lubrication system should be repaired and the lubrication system should be re-certified. Lubrication parts should be regularly refueled according to specific conditions. Frequently opened, high-temperature valves are suitable for lubricating parts exposed to the outside by refueling once a week to a month.

3, maintain the daily maintenance of the electric device

The maintenance of the electric device is generally not less than once a month. The maintenance content includes that the exterior should be clean, free of dust, and the device should not be contaminated by soda or oil; the sealing surface and points should be firm and tight. In addition, there should be no leakage, the lubrication parts should be oiled according to the regulations, and the valve socket nuts should be greased. In addition, the electrical part should be intact, no phase failure, automatic switch and thermal relay should not be tripped, and the indicator light should be displayed correctly.

In general, if you want to maintain the valve, you must do the corresponding cleaning work on the valve, and also need to maintain the lubrication of the valve and do the routine maintenance of the valve's electric device, so that the life cycle of the valve can be prolonged. Make it play more tangible value.
