Root valve of liquid chlorine storage tank
Thread Content
This post was last edited by sunjl1981 on 2013-1-6 at 20:37. When a root valve is installed at the outlet of the liquid chlorine tank (the liquid chlorine exit), can a short pipe be used between the root valve and the tank, or must it be installed directly on the tank’s outlet flange? Are there any regulations in this regard? # hcbbs
I haven’t seen any standards regarding this, but it’s best to install the root valve at the direct outlet of the equipment.
The standard design involves direct connection to the equipment’s flange, and it is a dual-valve design; I haven’t come across any regulations regarding this.
At the bottom, there are valves connected to the base of the tank; it’s a dual-valve system, with one valve on each side, one in the forward direction and one in the reverse direction
It is generally designed with two valves; there are no explicit regulations, but attempts should be made to avoid adding short circuits, as the goal is mainly to reduce the number of sealing points.
They are connected directly, with two valves—one positive and one negative; adding a short circuit would further increase the likelihood of leaks.
No such regulation was seen; generally, it is controlled by two valves
What is the main function of the 6# Dongchangjiang dual-valve setup with one valve connected in the forward direction and the other in the reverse direction? Will there be a problem if both are connected in the positive direction?
We have always used two valves in the same direction; I’m not sure what the purpose of using one in the positive direction and the other in the negative direction is.
