Balance valve is a digital control valve with a special function to determine the specific, mainly used to balance the pressure difference in the pipeline or flow difference, although the function is rather special, but in fact the balance valve itself is nothing special , From its working principle and characteristics can be seen. How it works: Selection of DC valve body structure, has a very good percentage flow characteristics, can reasonably distribute the flow, effectively handle the heating (air conditioning) system exists in the room temperature hot and cold are not in doubt. Together, the pressure drop and flow rates can be accurately adjusted to improve fluid activity in the pipe network, achieve liquid balance in the pipe network, and save energy. The valve has an opening degree indication, an opening determining device and a small pressure measuring valve used for the flow measurement. Only a proper standard balancing valve is installed at each branch and the user's inlet, and after one-time debugging with a dedicated intelligent instrument, The total system of water control in a reasonable range, and then overcome the "big flow, small temperature difference," the irrational scene. The balance valve can be either equipment on the water supply pipe, equipment can be on the return pipe, usually in the return pipe equipment, especially on the high temperature loop, to facilitate debugging, but also installed in the return pipe equipment balance valve for (Back) water pipes do not need to set stop valve. Equipments in the pipeline system balance valve, after its conditioning to change the system characteristics of the pipeline resistance ratio, arrived with the planning request common. After the system is qualified, there is no doubt about the static hydraulic imbalance. Commissioning of qualified systems such as at some load operating conditions, the total flow reduction by the balance valve of the branch pipe will take the initiative to cut the flow year on year, but the branch pipe set flow ratio unchanged. Balance valve is a special function of the valve, the valve itself no special place, only the use of functional and site differences. In some industries, because media (various types of moveable substances) have large pressure differentials or flow differences in each of the pipes or vessels, in order to reduce or balance this difference, between the respective pipe or vessel Set the valve, used to adjust the relative balance of pressure on both sides, or after the diversion of traffic to reach the balance of the valve is called the balance valve, the following to see its features: Balance valve features: 1, the ideal conditioning function; 2, excellent cut-off function; 3, accurate to 1/10 laps of the open situation appears; 4, the theoretical flow characteristics curve is equal percentage curve; 5, the national patent-type open and close to determine equipment; 6, There is a certain flow coefficient, debugging only need to measure the pressure difference between the two ends of the valve, you can easily calculate the flow through the valve; 7, PTFE and silicone seals, sealing reliable; 8, internal components use YICr18Ni9 or Copper alloy production, corrosion resistance, long service life; 9, within the stem lift, without reserve space for operation. 10, it is a combination of valves.

Switchable Film
Filmbase samrt film can paste on any smooth surface, it is clear when power on and opaque when power off. Smart Glass film is also called Switchable Film,Switchable Films,Custom Switchable Film,PDLC Film. There are three generations of smart glass in the market. Generations of smart glass are determined by manufacturing technologies of liquid crystal (LC) Switchable Film. In the industry, independent patented technologies are usually used to classify generations of products. For about three decades, there are only three independent patents in the field of LC switchable film. LC switchable film is also called liquid crystal film, LC film, Smart Film, Privacy Film, intelligent film, Electrochromic Film, electric film, electronic film, frosted film, pdlc film, PNLC Film, reverse film, reverse pdlc, reverse pdlc film, pdlc reverse film, opaque film; switchable glass, Privacy Glass, Switchable Privacy Glass , smart glass, electrochromic glass, Electric Glass, electronic glass, frosted glass, pdlc glass, pnlc glass, reverse glass, reverse pdlc glass, pdlc reverse glass, opaque glass or PDLC film.
