What is check valve? And what is the impact of its breakdown? This is news is going to talk about it.
After our home decoration, some water pipes have been installed with
check valves. Let's introduce how to repair the
check valve, so that we don't need to hire a water and electricity worker to complete one work which can be done by ourselves in person. The
check valve, also known as a one-way
check valve, is used to prevent reverse flow of fluid in the pipeline.
Here are some types of check valves:
Double clip lift check valve
Double disc butterfly check valve
Wafer check valve
Silent check valve
Micro resistance slow closing check valve
Rubber disc check valve
Silencing check valve
Lift check valve
Swing check valve
Slide ball check valve
Welded check valve
The importance of the
check valve in the domestic pipeline is to regulate the water supply through the pipeline. Understanding that changing the
check valve is a relatively simple process, which only requires some patience and hands-on ability.
Some faults of check valve
If the valve in the water supply system doesn’t work properly, and there are some chemical plants, industrial and mining enterprises nearby, this may lead to the main water supply pipeline being polluted.
In many cases of garden spray valve, the breakdown of check valve is relatively common. This puts fertilizers and other chemicals used in Horticulture at risk of entering the main trunk of the water supply. These two kinds of hazards are extremely harmful to people's health, and any owner for the check valve failure is not negligible.
Common reasons for replacement of check valve
If foreign matters other than water in the main water supply have entered the water supply pipeline, such as excessive water volume in the street after heavy rain, flood invasion, or the strength of some debris mixing into the water which is greater than the flow of the main system, the standard water flow will be deformed, and the increased pressure will cause the valve to burst, break or fall off. Siphon occurs when the pressure level in the main pipe system drops suddenly and a sudden difference in the general water level results in a vacuum. As a result, water may start to flow backward to the piping system, resulting in valve breakdown.
How to change the check valve in the garden ?
If the check valve on the garden sprinkler is to be replaced, simply remove the existing faulty valve and place it in place. The existing check valve will be fixed to the spray hose by fasteners. Remove the fixture with a wrench and gently move the faulty check valve away from the sprinkler hose. The instruction manual helps to install the return hose valve more easily. Make sure the new valve is clamped firmly. After completion, the valve is fixed in place with fasteners and can be put into use directly.
