If you have the patching feature turned on, you can wait for a short time to get a response. If it doesn't move all the time, it's a crash when patching, and there's no better way, only press the power on button to turn off the power (if you can't, you have to unplug the power, if you can't get into the system, you have to reinstall).
The system patching feature requires an automatic network connection, which is not easy to use on its own, and there is no better way to do it.
It is recommended to turn off automatic updates, use software updates, and make your own decisions at your own time, and now the antivirus software here has the function of patching, such as: 360, Kingsoft, QQ Computer Manager, etc.
How to turn off automatic updates:

The dynamic flow balance valve is used for water flow control, when the flow rate is large, the valve automatically closes small, and vice versa.
The door opens automatically. Stabilize the air conditioning duct flow.
The dynamic differential pressure balancing valve is a valve used for self-regulating the flow of two pipes, and self-balancing when the flow pressure difference between the second and first pipes exceeds a constant value.

ZLF (ZL-4M) dynamic flow balance valve, also known as self-operated balancing valve, flow control valve, flow controller, dynamic balancing valve, flow balancing valve, is an intuitive and simple flow regulation control device, the application of dynamic flow balancing valve in the pipe network can directly set the flow rate according to the design, the valve can automatically eliminate the flow deviation caused by the residual pressure head and pressure fluctuation of the pipeline under the action of water, no matter how the system pressure changes, keep the set flow unchanged, These functions of the valve make the flow adjustment of the pipe network complete at one time, turn the network adjustment work into a simple flow distribution, and effectively solve the hydraulic imbalance of the pipe network. The dynamic flow balancing valve is mainly used in water systems such as central heating (cold), so that the flow of the pipe network is distributed on demand, the hydraulic imbalance of the water system is eliminated, the problem of uneven cooling and heat is solved, and the energy saving and electricity saving are 15%-20%.
Performance characteristics of dynamic flow balancing valves:
The flow rate can be set according to the design or actual requirements, which can automatically eliminate the differential pressure fluctuation of the system and keep the flow rate unchanged.

Dynamic flow valves are constant flow valves, which are suitable for constant flow systems, or four-control systems, single cooling and single heating systems, and are not suitable for two-control systems. Also pay attention to the place of use, not cascade use.
The dynamic differential pressure valve can be used in a wide range of applications and can be used in two control systems. However, if you want to use it correctly and meet the requirements of the system, you also need to use a static balance valve, after all, the dynamic differential pressure valve only adjusts the differential pressure, and there is no flow restriction function, and the static balance valve is required to limit the maximum flow rate.
In addition, the dynamic differential pressure valve requires special instrument tuning, which is not as convenient as the dynamic flow balance valve.
The use of the two types of valves is relatively similar, basically at the system partition control port. It is rarely used directly at the end of the equipment (usually with a corresponding dynamic balance differential pressure control electric control valve).
Hope that helps.

Due to the manufacturers and technical strength, product quality, after-sales service and other factors, the first difference is very large. At present, the balance valve market products are uneven, and the selected products should be fully investigated and understood before purchasing. It's a good idea to visit the site.
There is not much difference in application with the static balance method, but in the adjustment of the pipe network, the static valve will be very cumbersome, the adjustment accuracy is relatively poor, and it cannot be adjusted independently like the dynamic valve.

There are several types of dynamic balancing valves. There are also several varieties of static balance valves, and there are many differences.
The dynamic balancing valve mainly keeps the water supply and return water in balance.
The flow force of the main branch pipe of the static balance valve is determined.

The dynamic flow balancing valve enables the valve to change according to the pressure difference of the water system from time to time, ensuring that the original set water flow rate will not be exceeded and the excess pressure difference will be absorbed, so as to realize the automatic balance of pressure and flow rate of the entire water system.
For the construction unit: save project costs and improve economic benefits.
No need to debug the system: it can save a lot of time for the project, shorten the construction period, complete the project ahead of schedule, save construction costs and improve efficiency;
There is no need to install Tongcheng management: it can increase the area and space used for the project, and save the cost of installation and materials.
For the owner: easy to use, easy to change, reduce energy consumption.
Easy to use: The construction of the project is more flexible, and the completion of the project installation in phases or the phased use of equipment will not affect the balance of the water system;
Easy to change: When the water system in some areas needs to be redesigned, it will not affect the water system design and balance in other areas;
Reduced power consumption: Because the entire water system is balanced, the refrigeration unit (boiler, heat exchanger) and water pump are guaranteed to operate in the best working condition, which has obvious energy-saving effects;
Reduced wear and waste: Ensuring that the water flow does not exceed the original design, ensuring the durability of all equipment and avoiding copper tube loss caused by excessive flow;
Increased safety: Since the flow rate of the water system is automated, there is no possibility of destructive adjustments.
For designers: less work, more flexibility.
Reduced workload: no tedious resistance calculations for the entire pipeline, speeding up design;
You can boldly use the different program system: save the pipe, the corresponding material and the installation cost, and leave the work of balancing the hydraulic system to the dynamic flow balancing valve;
Many other troubles caused by an imbalance in the water system can be avoided.

The pressure valve plays a role in pressure equalization or regulation by spilling excess pressure.
Whereas, the flow valve is to change the size of the flow of liquid or gas.
Flow valves are installed in the supply system in the hydraulic system and in the gas system are installed in the circuit system.
As for the air conditioner, I don't know very well.

The function of dynamic resistance balancing valve: dynamic resistance balancing valve is suitable for central heating system, and the installation of this valve in the heating network makes it easy for the heating network to achieve static and dynamic balance. It supports the operation of the heat source as the active variable flow rate.
In the user room, after installing automatic control devices such as thermostatic valves and thermostats, it can be converted into differential pressure control to realize user-oriented variable flow adjustment.
The dynamic resistance balancing valve has three functions: self-operated flow valve function, manual balancing valve function, and self-operated differential pressure valve function. The different conversions of the three operating modes of the pumps are realized.
Self-operated flow valve function for constant flow operation; The manual balancing valve function is used when the heat source is the main variable operation; It is converted to a self-operated differential pressure valve function when the user is active variable flow operation. Avoid frequent valve replacement of heating network and reduce heating costs.
