Introduction to Puhui brand SP45F digital locking static balance valve

Overview of Static Balance Valve SP45F Digital Lock Balance Valve
Static balance valve is a type of valve with special functions. Static balance valves have good flow characteristics, including valve opening indicators, opening locking devices, and pressure measuring small valves for flow measurement. Using a dedicated intelligent instrument, input the valve model and specific value, and directly display the flow rate through the balance valve based on the measured pressure difference signal. As long as appropriate static balance valves are installed in each branch and user entrance, and intelligent instruments are used for one-time debugging, the hydraulic and thermal balance of the system can be fully achieved. At the same time, by installing a static balance valve, the total water volume of the system can be controlled within a reasonable range, thereby overcoming the unreasonable operating conditions of "large flow and drought, small temperature difference". Practice has proven that the application of this static balance valve can generally save coal and electricity by 15% each.

Static balance valve controls flow by changing the interception port between the valve core and valve seat. Static balance valve can distribute water according to the pre calculated distribution ratio based on the design and calculation of balance. While increasing or decreasing the proportion of each branch, it can also meet the current demand for load flow and achieve balance. Adjusting settings requires professional tools, and non management personnel cannot arbitrarily change the opening degree; The function of a balance valve is to regulate the predetermined flow rate of each distribution point (such as each building) within the system. Balance valves are installed at the entrance of each building to distribute the total flow of the heating system in a reasonable manner.

Introduction to the principle of digital static balance valve

Static balance valve is a regulating valve with special digital locking function. It adopts a DC valve body structure and has better equal percentage flow characteristics, which can reasonably distribute flow and effectively solve the problem of uneven temperature in heating (air conditioning) systems. At the same time, it can accurately adjust pressure drop and flow rate to improve the liquid flow state in the pipeline system, achieve liquid balance in the pipeline system, and save resources. The valve is equipped with an opening indicator, an opening locking device, and a pressure measuring small valve for flow measurement. As long as appropriate balance valves are installed in each branch and user inlet, and a dedicated intelligent instrument is used for one-time debugging and locking, the total water volume of the system is controlled within a reasonable range, thus overcoming the unreasonable phenomenon of "large flow, small temperature difference". It can be installed on both the water supply pipe and the return pipe. Generally, it needs to be installed on the return pipe, especially for high-temperature circuits. For the convenience of debugging, it needs to be installed on the return pipe. The supply (return) pipe with a balance valve does not need to be equipped with a shut-off valve. Install a static balance valve in the pipeline system and adjust it to change the ratio of the characteristic resistance values of the system pipeline, in order to achieve consistency with the design requirements. After the system debugging is qualified, there is no static hydraulic imbalance problem.
If a system that has passed debugging is in partial load operation, the flow rate of each branch pipeline regulated by the static balance valve will automatically decrease year-on-year when the total flow rate decreases, but the flow ratio set for each branch pipeline remains unchanged.

A static balance valve is a regulating valve that is locked by an external device. It adopts a straight through valve body structure, which has better equal percentage flow characteristics, allocates resources reasonably, and effectively solves the problems of room temperature balance in heating (air conditioning) systems. Being able to accurately adjust pressure drop and flow rate, while improving fluid flow in pipeline systems, achieving the goal of pipeline fluid balance and saving resources. The valve opening indicator, locking device, and a small valve are used for flow measurement pressure. As long as the appropriate balance valve specifications are selected and the user inlet is equipped, there is a special one-time lock after debugging, and the total water control of the intelligent instrument system is within a reasonable range, thus overcoming the unreasonable phenomenon of "large flow, small temperature difference". It can be installed on the water supply pipe or the return pipe, usually on the return pipe, especially for high-temperature circulation. In order to facilitate debugging, it is necessary to install a static balance valve on the return pipe. After installing the balance valve, there is no need to set a shut-off valve on the pipeline. The static balance valve is installed in the pipeline system to adjust the pipeline resistance of the system to meet the design requirements.

Selection, model and diameter determination of static balance valve:

1. SPF45F digital locking static balance valve picture display: The left picture shows a balance valve with a cast iron main body, with a blue appearance and a red handwheel for adjusting the dosage. The image on the right shows a static balance valve made of all brass material. The picture shows a DN32 pressure of 16 kilograms, and the red handwheel is the adjustment handle. The valve body is marked with caliber, pressure, and flow direction. Small caliber valves are usually made of brass and connected by threaded connections, while cast iron main bodies are connected by flange connections. All of our SPF45F digital locking static balance valves are connected by standard connection size data for both flanges and threads, making it convenient to use static balance valves in conjunction with other equipment on site.

2. Adopting a scientific Y-shaped design static balance valve, with rotary adjustment and digital display of account size, it has the best control power and can accurately adjust HVAC circulating water or air conditioning systems. Balance the entire system to meet the requirements. Widely used in cold and hot water systems, it can effectively utilize energy to achieve energy conservation and improve energy efficiency. To determine the selection of caliber specifications, the first step is to choose a static balance valve with the same diameter as the pipeline to meet the flow requirements as the benchmark. If the required flow rate is achieved, a larger caliber valve needs to be selected to meet the flow requirements as the standard.
