Screw air compressor working principle of temperature control valve, temperature control valve of electromagnetic early temperature control valve, in recent years through the digestion and absorption of imported air compressor technology, wax temperature control valve or more applications, and wax temperature control valve consists of valve and original of the temperature control of two parts. The original temperature control by special thermal expansion paraffin and copper shell, in a specific phase transition temperature, the expansion of the expansion of paraffin stress is a constant value, far outweigh thermostatic valve required thrust. Paraffin wax seal in the shell, when the temperature rises to the paraffin wax melting point, the volume expansion and push the plunger. Driving temperature control valve, valve movement; When the temperature drops, paraffin encounter cold shrink, in the spring under the action of the springback, reset of the valve. Wax temperature control valve
The characteristics of temperature control valve: thrust, the original internal paraffin expansion can reach more than 200 atmospheres, trip temperature curve linear good, therefore temperature control ability is strong, element rigidity, high intensity, long service life.
Structure principle: self-reliance type regulator is mainly composed of valve body, valve seat and valve disc, valve cover, bulb, adjusting nut and other components. According to the exit temperature modulated medium size inlet valve to automatically adjust the heat source, heat source and the heating medium can adopt its own loop system already, also can be used directly mixed heating system. Temperature control valve consists of a control valve and a thermostat (contains a temperature sensor, a set point adjuster, a capillary tube, and a piston), depend on the choice of different state of temperature applications. Temperature control valve according to the principle of liquid expansion operation, if the temperature on the sensor, will make the liquid filler heat and inflation at the same time, in the work under the action of piston valve is closed, the cooling medium at this time. Through the set-point key can adjust step by step, can read on the scale. All the thermostat is equipped with a device of overtemperature protection. Temperature control valve is the most suitable for the installation work of piston top at the bottom of the horizontal. Temperature sensor can be installed in any position, the length must be immersed into the accused of medium.
Function: temperature regulator is self-reliance type temperature control valve, does not need additional energy, by adjusting the control set point temperature. When the temperature increases, the closing of the proportional valve according to temperature changes. Self-reliance type valve without any external energy, use energy from the modulated medium itself, to realize automatic temperature adjustment, has a wide range of setting, clear display, high precision, and has the overload protection device, safe and reliable, which is widely used in industrial production process automation control. At the same time also applies to refrigeration or heating, water supply, the sterilization temperature automatic adjustment of the equipment. Marine diesel engine fresh water lubricating oil temperature control is accomplished by the thermostat.
