The important function of intelligent water meter valve is introduced
Automatic constant pressure differential valve + electric regulator is used to solve the air conditioning water system balance is a very good method, when the system pressure changes, the constant pressure difference valve can by changing the flow area of their own to make differential pressure at the ends of the electric control valve remains the same, the regulator of the CV value is always one, thus ensuring electric regulator has been running at the * * ideal condition, Truly do the change of water is only related to temperature and has nothing to do with pressure, you can ensure that the amount of water into the air conditioning box is the amount of water you need at any time. Cluster and make the system more superior performance, more convenient maintenance.
At the end of the system using automatic differential pressure valve + electric control valve can save a lot of use in stratified control of the balance valve, so you can make the system performance more superior, more convenient maintenance.
Automatic constant differential pressure valve + electric control valve is an important guarantee of hydraulic balance of variable flow air conditioning water system. Using automatic balance proportional integral control valve in the system can bring you many benefits.
1. Because there is no need for system debugging, it saves a lot of trouble, saves a lot of time and shortens the completion date.
2. Because there is no need to use the valve group and the valve for stratified control, so you can save more pipes, insulation materials and installation costs and time.
3. The water system is always in a state of balance, so no matter the installation stage construction or equipment stage use will not affect the balance of the water system.
4. Even if the water system design of some areas needs to be changed due to the change of some uses at the later stage of the project or after it is put into operation, it will not affect the water system design of other areas, let alone the water system balance of other areas.
5. Because the whole system is in a state of dynamic balance, so the refrigeration unit and water pump will run in the most energy saving state, saving a lot of operation and maintenance costs.
6. Because the flow balance of the system is automatically carried out, the installation and maintenance is more convenient, and the possibility of destroying the balance by human operation error is eliminated.
Comparison between automatic balance proportional integral control valve and static balance valve
Static balance valve is actually a kind of cut-off valve which can be set artificially precisely. It can solve the hydraulic balance problem of the pipeline part of air conditioning water system by artificially adjusting local resistance. At the beginning of the system debugging, all the valves of the system are in a certain opening, the debugger according to the original mathematical model one by one for each static balance valve opening set (set valve opening for a certain value), but for different water systems the resistance distribution curve is not the same, and can not be measured. Therefore, static balance valve can only fuzzy, qualitative control of water flow. For a variable flow air conditioning water system, the change of the water volume of each air conditioning box is random, the change of the pressure of the whole pipeline system is not measurable, and the change of the opening of the regulating valve is random. So we start with the formula
G (flow) =CV*A (valve flow area) *△P (pressure difference between both ends of the valve) can be obtained:
Because the static balance valve after adjusting the opening for a certain value. Therefore, changes in the pressure difference at both ends of the valve will inevitably lead to changes in the flow through the static balance valve. So in a variable flow system when the pressure of the system changes static balance valve is unable to solve the problem of hydraulic imbalance. Overcurrent and undercurrent may still occur in the system.
The important role of intelligent water meter valve 镃 valve is the most important part of intelligent water meter, playing a very important role. The valve is the heart part of the water meter. If the “heart” of the water meter stops working, the water meter ends its life.
镃 valve is the most important part of intelligent water meter, playing a very important role. Here are the details
The valve is the heart of the meter. If the heart of the meter stops working, the meter ends its life.
The valve of intelligent water meter is the most important part in the intelligent water meter, and it is also the most important part. The quality of the valve directly affects the service life of the water meter.
Applied in the intelligent water meter better electric ball valves, valve between his ball valve core and valve body adopts suspension structure, on the premise of guarantee close valve closed not leak, left a gap between valve core and valve body, with suspension structure, can realize the pressure loss of small, wear small, low consumption, the effect of anti rust, anti clogging. On the one hand, it improves the reliability and life of the valve, on the other hand, it reduces the load power consumption of the IC card water meter battery, and on the other hand, it ensures the life of the battery.
