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. Temperature control valve (core) product
