How long after installation will the check valve work properly?

‌After the check valve is installed, if it is installed correctly and the pipeline system is in good condition, it can usually work normally immediately‌. However, to ensure its stability and safety, it is sometimes necessary to wait for some time for observation and testing.

As a key component in the fluid pipeline, the check valve is mainly used to prevent the medium from flowing back and ensure the normal operation of the pipeline system. Its working principle is to rely on the weight of the opening and closing parts (valve disc) and the medium pressure to achieve automatic opening and closing. When the medium flows in from the inlet end, the valve disc is pushed open and the medium can flow; when the medium flows back, the valve disc is closed to prevent the medium from flowing back‌.

When installing the check valve, it is necessary to ensure that the installation process is strictly carried out according to the specifications, including selecting a suitable installation location, correctly connecting the pipeline and the valve, and adjusting the opening and closing status of the valve. If there is negligence or errors in the installation process, the valve may not work properly or even cause a safety accident. Therefore, after the installation is completed, the installation process needs to be carefully checked to ensure that it is correct‌.

In addition, the overall condition of the pipeline system will also affect the use of the check valve. If there are impurities, dirt, or uncleanness in the pipeline system, it may affect the sealing and normal operation of the valve. Therefore, the pipes need to be cleaned before installation to ensure that the pipe system is in good condition.

In some specific cases, such as check valves installed in sewers, to ensure their stability and tightness, it is sometimes necessary to wait for some time (such as 3 hours) before use. However this is not a universal rule, and it depends on the installation situation and the condition of the pipe system.

In summary, whether the check valve can work properly immediately after installation depends on many factors, including the standardization of the installation process, the overall condition of the pipe system, and the medium used. In most cases, if the installation is correct and the pipe system is in good condition, the check valve can work normally immediately. However, to ensure its stability and safety, it is recommended to conduct necessary observations and tests.
