valve is a control device which can make the water system achieve dynamic and
static balance regulation. It is divided into dynamic balance valve and static
balance valve. Static balancing valve is also known as manual balancing valve,
digital locking balancing valve, hydraulic balancing valve and so on (in this
paper called hydraulic balancing valve).
Dynamic balancing valves are divided
into dynamic flow balancing valves and dynamic differential pressure balancing
can be divided into flow type and adjustable flow type. The
so-called constant flow type is commonly referred to as the valve gallbladder
type, the factory flow has been set, the site can not be adjusted (that is,
piston type). Adjustable flow field can adjust and set the flow.
Dynamic balancing valve is also called self-operated flow control valve, self-operated
balance valve, constant flow valve, automatic balance valve, etc. In October
2003, the relevant standards of the Ministry of Construction were issued as self-operated
flow control valves.
differential pressure balancing valve is also called self-operated differential
pressure control valve, differential pressure controller, constant voltage
variable synchronizer, differential pressure balancing valve, etc. This paper
is called self-operated differential pressure control valve. Dynamic
differential pressure balancing valve can be divided into fixed differential
pressure type and adjustable differential pressure type. The constant pressure
difference type sets the control pressure difference for the factory. The
adjustable differential pressure model is that the magnitude of the
differential pressure can be adjusted and controlled on the spot.
