No external energy is required for automatic temperature adjustment. It is suitable for steam, hot water, hot oil and other heat exchange applications for the medium. And widely used in heating, air conditioning, domestic hot water temperature automatic adjustment, as well as special occasions, automatic temperature adjustment, such as chemical, textile, pharmaceutical and other production processes. The automatic adjustment is achieved by using the principle of thermal expansion of the liquid and incompressibility of the liquid. The expansion of the liquid within the temperature sensor is uniform and its control is proportional. As the temperature of the controlled medium changes, the volume of temperature-sensing liquid within the sensor expands or contracts. When the temperature of the controlled medium is higher than the set value, the temperature liquid expands, pushing the valve core down to close the valve to reduce the flow; when the temperature of the controlled medium is lower than the set value, the temperature sensitive liquid shrinks, and the reset spring pushes the valve core to open. Increase the flow of heat medium.
It can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil products, liquid metals, and radioactive media. The valve is nominally passed through a few millimeters of gauge needle valves to 10 meters of industrial pipeline valves. The working pressure of the valve can be from ultra high pressure of 1.3×10-3MPa to 1000MPa. The operating temperature is from -269°C to 1430°C. The valve can be opened and closed by a variety of control methods, such as manual, pneumatic, electric, hydraulic, electro-pneumatic or electro-hydraulic linkage and electromagnetic drive; it can also be under the effect of pressure, temperature or other forms of sensing signals. Operate as intended, or simply open or close.
Nominal pressure or pressure level: PN1.0-32.0MPa, ANSICLASS150-1500LB, JIS10-20K Nominal diameter or bore diameter: DN10 ~ 500, NPS1/2 ~ 36" Connection: flange, butt weld, thread, etc. Applicable temperature: -196°C～700°C Drive Mode: Manual, Bevel Gear, Pneumatic, Electric, Hydraulic, Air-Liquid Linkage, Electrohydraulic Linkage Body Material: WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8(304), CF3(304L), CF8M (316), CF3M (316L), Ti. Use different materials, which can be applied to various media such as water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea, etc. Valves in this category should generally be horizontal installation.
Electric three-way regulating valve is light, sensitive, accurate flow characteristics, control signals and single-phase power can control the operation, to achieve automatic adjustment and control of the process pipeline fluid medium, widely used in precise control of gas, liquid, steam, etc. Medium process parameters such as pressure, flow rate, temperature, level and other parameters are maintained at a given value. The utility model is suitable for the condition that a fluid is divided into two flows through a three-way valve or the two fluids are combined into a fluid through a three-way valve.
