Number of valves installed on the same pipeline
Thread Content
For example, on a pipe, when cast-iron valves are connected to each other (with a rigid connection, without any flexible connectors in between), how many valves can be connected at most? Are there any regulations regarding this?
In practical applications, sequences of 5 or fewer valves are more common; is it used for displaying valves, by arranging multiple valves together to create a certain design?
If the pressure difference exceeds 4 MPa after the valve is closed, 2 valves can be connected in series. What is the pressure difference in your operating conditions?
You can string as many as you want, as long as you have the money
Rich, willful! If you want to use a valve as a pipe without considering pressure loss, in theory, an unlimited number of them can be connected in series! It is impossible in actual design and installation.
It’s not about displaying the valves; now that the valves have been connected, the flange bases of the valves are cracked
This is my water supply pipeline; the pressure difference can’t be that high. I just want to check if there are any regulations regarding this
Take a look at the previous picture. (How many have you strung together?) ）
Five valves, three self-fabricated straight pipe sections; the total length is about two and a half meters. I don’t know how to upload pictures :L
