Cooling type temperature control valve is a kind of driving without external energy, depending on the medium itself was transferred energy as power source and medium temperature change, according to a predetermined set value for energy-saving automatic control device. It sets detection, control, implementation of many functions in a valve, from an independent instrumentation control system. The product is composed of low flow resistance (single seat valve, sleeve) composition, temperature and equilibrium temperature setting mechanism, its characteristics are: 1, without additional energy saving control system of power equipment, low cost, suitable for explosive environment; 2, simple structure, small maintenance workload, set point can be 3; adjustable wide range, convenient for the user to adjust continuously in the range of set value; 4, a temperature overload protection device, safe and reliable; the pressure balancing mechanism 5, the valve, the valve is sensitive and accurate control, allowing a large pressure difference. Because the product without external energy, has the advantages of simple structure, convenient use, less maintenance workload, especially suitable for city heating, heating and power supply, gas supply and no need to control the liquid and gas. According to foreign reports, the city heating, heating system using the product, energy efficiency increased by 40% 30%- than before, the effect is significant.
Note: parameters for reference only, or incomplete. Valve can be selected according to the requirements of different pressure, material, caliber, drive, etc.. Specific call contact or online consultation.
Regulating valve by the main valve, intelligent actuator and sensor three parts, according to user needs, respectively, heating and cooling type of two structures.
Working before the main spool in the semi open position, the sensor is in a natural state. Connect the power supply, the main spool fully open. The medium flows into the main valve body from the arrow direction and heats the heat storage box through the valve core. When the temperature rises to the corresponding set value, the sensor generates the corresponding linear signal input integrated intelligent actuator, then drive the stem, spool displacement, closing the main spool stop heating. When the temperature is lower than the set value, the sensor generates a linear signal input actuator, driven spool gradually open, so that the media into the parabolic box according to parabolic characteristics, heating until the set value. This controlled medium is always controlled within the set temperature range, so as to achieve the purpose of temperature control.
