The self-operated control valve does not require external force or action to operate, it operates according to temperature. The valve that adjusts itself according to the temperature. Self-operated temperature control valve is suitable for various heat exchange situations such as steam, hot water and hot oil. It is widely used in some temperature regulation projects. It is suitable for various heat exchange conditions with steam, hot water, hot oil, etc. as the medium. Widely used in heating, air conditioning, automatic temperature adjustment in domestic hot water, and automatic temperature adjustment in special working conditions, such as chemical, textile, pharmaceutical and other production projects. Working principle The self-operated temperature control valve realizes automatic adjustment by using the principle of liquid expansion by heat and incompressibility of liquid. The liquid expansion in the temperature sensor is uniform, and its control function is proportional regulation. When the temperature of the controlled medium changes, the volume of the temperature-sensing liquid in the sensor expands or contracts with it. When the temperature of the controlled medium is higher than the set value, the temperature-sensing liquid expands and pushes the spool down to close the valve, reducing the flow of the heating medium; when the temperature of the controlled medium is lower than the set value, the temperature-sensing liquid shrinks and the return spring pushes The valve core opens, increasing the flow of heat medium. Features 1. Easy to install. 2. No power supply air source is required. 3. Easy to adjust and set. 4. Balanced valve core design. Remarks for main technical performance indicators: KVS means that the medium is water; the maximum flow rate of the valve (m3/h) when the temperature is 20 °C and the pressure difference is 1 bar Pressure, working pressure, heat medium pressure and temperature, controlled medium and temperature requirements. 2. The length of the general conduit is 3.5-4.5m, if there are special requirements, please specify. 3. If you need other special-purpose temperature control valves, please contact the company directly. Features It is an actuator product that uses the energy of the medium to be adjusted to automatically adjust the temperature of the medium without any external energy. It has a wide temperature setting range, clear display, high precision, and is equipped with an overload protection device, which is safe and reliable, so it is widely used in chemical industry, petroleum, electric power, metallurgy, food, textile, civil buildings, hotels, Automatic temperature adjustment of various heating, water supply, refrigeration, sterilization and disinfection equipment such as restaurants. Application Self-operated temperature control valve, also known as temperature control valve, self-operated temperature control valve, temperature control valve, temperature control valve. It consists of control valve and thermostat. It is divided into heating type and cooling type according to the application. The self-operated temperature control valve is mainly composed of a control valve and a thermostat. It is an energy-saving product that does not require external energy and relies on the temperature change of the controlled medium to automatically adjust. Suitable for non-corrosive liquids, gases and vapors, temperature control in various cooling systems. When the temperature of the controlled medium rises, the control valve closes (heating type); when the temperature of the controlled medium rises, the control valve opens (cooling type). The above is the introduction to the self-operated temperature control valve. I wonder if everyone understands it?
