In electric power, chemical industry, petroleum, metallurgy and other enterprises, a large number of heat exchange and expansion equipment need to control the liquid level by adjusting the outlet flow. At present, most of the products used are mechanical floating ball type, electric type and pneumatic type. These products not only have high cost and complex control, but also have frequent actions of actuators, which are easy to jam, wear, cavitation and leakage. High cost of maintenance, resulting in significant impact on equipment safety. It can be seen that the self-adjusting liquid level control device with excellent performance and high reliability is the product urgently needed by enterprises to improve economy and safety.
In the past, most of the similar equipment had the disadvantages of compromise adjustment, low sensitivity and large error rate. Some of them had to be changed to manual operation to increase labor intensity. It has a serious impact on the economy and safety of the equipment. Some of them cause serious economic loss to the operation personnel.
The self-adjusting liquid level control device of vapor-liquid two-phase flow has the characteristics of strong liquid level control ability, high reliability, maintenance free and long service life. It is an updated product of traditional drainage control equipment. it can be widely used in high and low pressure heaters, shaft seal heaters, heat supply network heaters, boiler continuous exhaust equipment and heat exchange equipment and expansion vessels of metallurgical, petroleum, chemical and other enterprises. It can completely solve the problem of liquid level control for 300MW, 600MW and above units in power plants and related equipment in petroleum and chemical industry.

Application of two-phase liquid level self regulating device in electric power industry
The self regulating liquid level control device of steam-liquid two-phase flow breaks through the limitation of the original technology, and has been widely used in the high-pressure and low-pressure heaters, shaft seal heaters, boiler continuous blowdown and heat supply network heaters of 600MW, 300MW, 200MW and below units in the power industry. With superior performance, advanced technology, excellent quality, accurate water level control and maintenance free, it is the preferred product to replace the traditional liquid level device.
Common faults of traditional heater products
1) The water level control of traditional products is not good, resulting in long-term low water level operation.
2) Traditional products have high failure rate, heavy maintenance workload and frequent maintenance.
3) It is difficult to control water level, which results in the decrease of unit economy and low thermal efficiency.
4) The poor control of water level will cause pipeline vibration, which will lead to serious safety accidents such as weld crack, thermal insulation material flying and high pressure steam overflowing.
In view of the above problems, our factory and the Institute of thermal power of Chinese Academy of sciences have developed a new type of steam Huaihe phase flow automatic regulating device, which has successfully replaced the old equipment. It can not only implement the transformation on the basis of the original old equipment, but also provide reference for the design institutes of major research institutes in selecting and matching new equipment when designing and updating new equipment.
??? The new vapor-liquid two-phase flow device It uses the difference between liquid flow value and vapor flow value to design and configure the sensing signal and regulation system. It uses the most economical method to effectively mix the vapor phase and liquid phase. In order to achieve the maximum and keep the steam and water recharge in the best state. So as to eliminate the phenomenon of false detection, misoperation and automatic failure, and improve the efficiency and safety of the main equipment.
? The models of self-adjusting liquid level controller, steam water two-phase flow trap and liquid-liquid two-phase flow level controller are introduced
Advantages of Taige liquid level control device

5) No leakage, good safety performance.
6) Reduce cavitation and vibration.
7) The system is simple and easy to install.
8) Good corrosion resistance.
9) Special material, long life.
10) It has wide application range and strong adaptability.
Working principle of vapor-liquid two-phase flow device:
Based on the principle of "vapor-liquid two-phase flow", a self-adjusting liquid level control device is installed to automatically adjust the liquid flow at the outlet of the container to achieve a more stable liquid level. According to the basic design principle, the liquid level is directly mixed with the inlet of the steam trap. When the liquid level rises, the vapor phase signal decreases, so the drain flow rate increases; when the liquid level decreases, the vapor phase signal increases, reducing the effective flow area of the throat, and the drainage flow rate decreases, so as to effectively block the drainage.
It is based on the "liquid-liquid" signal acquisition device, which can directly control the gas-liquid level, The design idea of adding signal pipe and new double throat structure to the old self regulator is reduced, and the problems of low accuracy of liquid level control and inaccurate signal acquisition of early products are solved. At the same time, the regulating steam volume is reduced, the cavitation and vibration of rear pipeline are weakened, and the benefit and safety of main equipment are improved
