YF-S self-regulating level controller

YF-S self-regulating level controller self-regulating level controller is based on the vapor-liquid two-phase principle has been patented energy-saving new technology products. Widely used in electric power, chemical, petroleum, metallurgy and other enterprises of all types heat exchangers, expansion of the level control, safe operation and to achieve the purpose of energy saving, it is the traditional hydrophobic regulator replacement products. I. Introduction self-regulating level controller is based on the vapor-liquid two-phase principle has been patented energy-saving new technology products. Widely used in electric power, chemical, petroleum, metallurgy and other enterprises of all types heat exchangers, expansion of the level control, safe operation and to achieve the purpose of energy saving, it is the traditional hydrophobic regulator replacement products. The traditional float, pneumatic and electric actuators due to the control level device complexity, frequent movement, often resulting in Jamming, disclosure, no running water, drains and serious erosion problems. Thus failure rate, poor reliability, not only repair and maintenance workload, but also reduces the turbine efficiency, the impact of unit economics. The balancing type level from the regulator put into use, the effective solution to this problem. It uses the "vapor-liquid two-phase flow" principle, continuous automatic adjustment of water level, water level controller abandon the traditional mechanical moving parts and electrical control components, itself without any moving parts, well overcome the permanent fault traditional Water Level Controller that the water level control problems have been a better solution. Because of the novel, advanced theory, the structure is simple and practical by the majority of users. The product has been a lot of industrial applications, with good results, and through the identification of acceptance. Experts agreed that: "The device the novel, working principle is simple, self-regulating ability, level control and stability means small, small parts, structures and systems simply no mechanical moving parts, no electrical components, thus their reliability. security is particularly prominent. Installation is easy, especially for the old equipment level controlled transformation means, also suitable for corrosive environments and media, with a wide range of applications. " "There are significant economic benefits of energy saving," "advanced technology and reliable, better than the other domestic level controlled device." Second, the principle of the product is based on the "vapor-liquid two-phase flow" principle, the use of vapor-liquid change of self-regulating characteristic control container exports and the design of a new type of liquid level controller. Abandon the traditional float, pneumatic, electric control equipment level disadvantage, automatically regulate the flow of the liquid container exports, so as to achieve a more stable level. The basic principle is: a hydrophobic cavity from the valve body into the valve inlet pipe phase transition (signal tube) according to the level of collected fluid vapor, liquid signal directly into the valve chamber, and a hydrophobic mixture through a specific design of the throat. When the liquid level rises, the vapor-phase signal reduction, thus increasing the hydrophobicity flow; when the level drops, steam believe increased number, reducing the effective flow area of ??the throat, hydrophobic flow is reduced to achieve effective hinder hydrophobic purposes. Third, the product features 1, automatic continuous adjustment, self-regulating ability, a relatively stable level. 2, the product has no moving parts, no mechanical and electrical transmission equipment, advanced design principles, good reliability, free from outside interference, anti-interference ability, high safety performance. 3, fully enclosed structure, no leak product. Structure and system is simple, easy on-site maintenance and repair. Equipment required to meet the long-running 4, easy installation, construction, transformation of the old equipment easily, combined with the actual site design. Spool with a good stainless steel, corrosion, wear resistance, long service life. 5, the price is lower than or close to the traditional level regulator, far lower than similar foreign products. Fourth, the product scope of the product is suitable for the power industry high and low pressure heaters, continuous blowdown; water heaters and other heating network controls the pressure vessel. Level control applies to the petroleum, chemical and metallurgical sectors of various types of containers. Fifth, user feedback application level since the regulator, on-site maintenance, and operation and maintenance of a significant decline in workload, saving maintenance costs, reduce labor intensity. Secondly, because the level is not self-regulating pneumatic and electric thermal control system and complex thermal ancillary equipment, thereby reducing maintenance personnel, greatly improving the management level of equipment. User called maintenance-free device. Conventional thermal power plant water heater controller failure frequently, after field use level since the regulator said the problem been solved, saving a lot of energy, and its social efficiency and significant economic benefits.
