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.
调节阀由主阀、智能执行器与传感器三部分组成,根据用户需要,分别有加热型与冷却型两种结构。
工作前主阀芯处于半开位置,传感器处于自然状态。接上电源,主阀芯全开。介质由箭头方向流入主阀体、经阀芯对储热箱进行加热。当温度升到相应设定值时,传感器即产生相应线性信号输入一体化智能执行机构,随即驱动阀杆、阀芯产生位移,关闭主阀芯停止加热。当温度低于设定值时,传感器即产生线性信号输入执行机构,驱使阀芯渐开,使介质按抛物线特性流入储热箱,进行加热直至设定值。这样被控介质始终在设定温度范围内被控制,从而达到控温目的。
