Control valve, whether the execution head is above or below
Thread Content
A regulating valve on a steam turbine. Why is the actuator head at the bottom? When is it usually placed at the bottom?
I guess it's difficult to install from the top...
The installation method of the self-supporting pressure regulating valve is determined according to the medium. Generally, this is the installation method for steam.
Can you send me the complete information?
I only have a paper version here. You can search for self-supporting pressure regulating valve tonight and take a look.
And your two stop valves, why are they not installed vertically? Is this the way they were designed?
The gas is at the top and the liquid is at the bottom.
If you know the principle of the self-operated regulating valve, I won’t go into details. There is a rubber pad inside the regulating valve cylinder to prevent the steam from penetrating the rubber pad. Therefore, a condensation tank is installed in the front and it is installed downwards, which saves a lot of trouble. As long as the condensation tank is not removed, the water inside will remain there. If it is installed upwards, it stops or breaks down, it is necessary to refill the isolation fluid to avoid unnecessary work. Install it downwards.
I think the installation is reasonable because in actual production applications, it is convenient to operate the switch and facilitate maintenance and repair. Because in many places the operators are female. It is not a problem of design, but for reasonable installation in production. The design institute will not care how you install it.
