Watering can failure phenomenon and repair method

The watering can is generally used by everyone. Everyone knows that the nozzle cap is tight and loose, which can adjust the diameter of the jetted water column and the amount of water. After a long period of use, it is often difficult to use the fault. The following is a method of repairing the watering can for you to edit it, I hope to help you.
The first case of the spray can malfunction and repair is unsatisfactory, and the sprayed water mist is not round and unilateral, but there is pressure inside the kettle. The main thing is to see if there are some small passages that are blocked.
1 Unscrew the nozzle cap and see if there is any garbage jam in the small hole of the spray cap. The small hole of the spray cap is very small. If there is garbage, it will be unpleasant or not unilateral. Then the board is turned on and off a few times. Normally, 2 water columns should be sprayed evenly.
2 Rotate the copper tube again. When the spray cap has been unscrewed, look at the side of the copper tube from the end of the copper tube. Look at the light. Normally, you can see a trace of light. Otherwise, the garbage is blocked. The wire is cleaned up a few times.
3 The board is switched, the sprayed water mist is not round and unilateral, and there is less on the other side. In addition to seeing the half of the small hole of the spray cap, there is no waste, but there are also two carved passages on the nozzle. The rotating water flow can be formed at the time (of course, the water flow is small through the spray cap)
After the hole is not rotated, one of the two channels is blocked, and the sprayed water mist is not round.
4 Unscrew the pot head and see if the filter hole at the lower end of the thin soft tube is clogged. The soft tube is transparent. If the inside of the tube is clogged, you can pull out the soft tube and clean it with a thin wire.
The second case of watering can failure and repair
Lifting up and down, pressing the handle feels light, no power, no pressure inside the pot. Water can't be sprayed.
1 Tighten the sealing joints at 3 places. The pot head and the pot body are often unscrewed and added with water. There is no screwing here and air leaks.
2 The aprons in the piston combination are worn or have rubbish, and the air is shut off. This requires unscrewing the cylinder and pulling out the piston combination to observe (there is some grease in the piston combination). The grease added to the rubber ring may improve the sealing.
3 The one-way valve at the lower end of the cylinder is aged or embedded with garbage, and the water leakage is not tight. Some one-way valves protrude, which can be clearly seen, but some one-way valves are actually a few slits at the lower end of the cylinder, which cannot be seen carefully. Look at the picture.
The third case of watering can failure and repair
When there is pressure, water is continuously pulled out beside the handlebar until there is no pressure or the water in the kettle has leaked. Unscrew the cylinder and pull out the piston combination.
1 Mainly look at whether the one-way valve has garbage embedded, whether there is garbage in the piston combination, and if there is garbage, it will close and leak water.
The one-way valve only allows air to enter the kettle and does not allow water to come up. During the inspection, the handle and the piston combination at the lower end can be pulled out, the water is filled in the piston cylinder, the handle and the piston are loaded, and the handle is pressed down, and the water and air can be seen to be ejected from the one-way valve and simultaneously punched. Drop the embedded garbage.
2 There are watering cans, there are 2 hard plastic pieces in the piston, which can restrict the aprons from moving up and down in a small range. One of them can be screwed up and down, and the distance between the two hard plastic pieces is large. When you move, you can't seal the air passage, and you will leak water. Tighten the hard plastic sheet.
Spray bottle failure phenomenon and repair of the fourth situation
After a long period of time, the original pressure is gone, and it is necessary to check whether the three sealing rubber rings are tight or aging, resulting in chronic air leakage.
The fifth case of watering can failure and repair
There is no plate switch, there is still water leaking from the nozzle. This is very simple. The switch bar does not tighten the rubber pad. Rotate the copper pipe to see if there is any garbage on the rubber pad and the switch bar. The spring behind the switch bar has no elastic force. Whether it is stuck by garbage.
