What. Are The Related Notices For The Check Valve
Check valves are used as an automatic valve in the pipeline to prevent the reverse flow or leakage of the medium in the pipeline. There are various
types of check valves on the market. There are also a variety of design forms, such as connecting forging steel check valves, sealing forged steel
check valves and so on. Whatever type of check valve, it can be well protected. The one-way flow of the stop medium or the action of preventing
backflow. So what should we pay attention to during the process of istalling and insalling check valves?
The check valve is automatically circulated or closed by pressure, so a check valve should be installed on many equipment and pipes, but the check
valve should not be weighed when the check valve is installd on the pipe, and an independent support should be made if a large check valve is
installed. Because this enables the check valve not to be affected by the pressure generated in the piping system. When installing the check valve, it
should be installed according to the flow direction of the medium in the pipe and do not install the check valve.
In addition, the form of check valves in different positions is diferent. If it is a vertical pipe, the corresponding liting vertical valve should be installed
on it, and the horizontal valve should be installed on the horizontal pipe. When installing the check valve, do not use the pipe joint within the operating
radius of the valve plate, and also avoid other obstructions, as this will affect the operation of the check valve.
The installation of the pipe is unavoidable to the need to bend the part, in the bending part of the installation of check valve, the need to keep enough
space with the bending part to avoid the check valve under the pressure of the bending part of the pressure. When check valve is used, the relative
resistance value of check valve should also be understood.
High quality check valve has many advantages, such as light weight, small size, sensitive movement, high relibility, beautiful appearance, simple and
compact structure and good sealing performance. Therefore, if the check valve really plays its role, attention should be paid to some check valves,
and the correct use of check valves can be used to manage the pipe well. The flow of the medium in the channel.
