Balance valve features:
1, the ideal conditioning function;
2. Excellent cut-off function;
3. Accuracy to 1/10 laps of open conditions appears;
4. The theoretical flow characteristic curve is an equal percentage characteristic curve;
5. National patent-type opening and closing determination equipment;
6, corresponding to each full circle has a fixed flow coefficient, debugging only measured pressure difference between the two valves, you can easily calculate the flow through the valve;
7, PTFE and silicone seal, reliable sealing function;
8. The internal components are made of YICr18Ni9 or copper alloy, which has strong corrosion resistance and long service life.
9, the lift valve stem, no need to reserve operating space.
10. It is a combination valve.
Balance valve operating principle:
The use of DC-type valve body structure, has a very good equal percentage flow characteristics, can reasonably distribute the flow, effectively deal with the heating (air conditioning) system exists in the room temperature hot and cold inequality doubts. Together, pressure drop and flow rate can be accurately adjusted to improve the liquid activity in the pipe network system, reaching the liquid balance of the pipe network and saving energy. The valve is provided with an openness indication, opening determination device and a small pressure measurement valve for flow measurement. It is only necessary to install an appropriate standard balance valve at each branch and user's inlet, and determine after a one-time commissioning with a dedicated smart meter. The total amount of water in the system was controlled within a reasonable range, and then the unreasonable phenomenon of "large flow and small temperature difference" was overcome. The balancing valve can be either on the water supply pipe or on the return pipe. Usually the equipment is on the return pipe, especially on the high-temperature loop. To facilitate the debugging, the balance valve must be installed on the return pipe and the balance valve should be provided. (Back) The water pipe no longer need to set the cut-off valve.
In the pipeline system, the equipment balance valve is adjusted to adjust the resistance ratio ratio of the system pipeline, and arrives together with the planning request. After the system is qualified, there is no question of static hydraulic imbalance.
If the commissioning system is in a certain load operation condition, the branch pipes conditioned by the balance valve will actively reduce the flow while the total flow is reduced, but the flow ratios set by the branch pipes will not change.
The balance valve is a kind of valve with special function. The valve itself has no special place. It only uses the difference of function and field. In some industries, because the medium (various types of movable substances) has a relatively large pressure difference or flow difference between the pipes or containers, in order to reduce or balance the difference, between the corresponding pipes or containers Valves are installed to balance the relative balance of pressure on both sides, or to achieve a balance of flow through a diverted approach. The valve is called a balancing valve.
