The Introduction of ProductsThe ZWT self-operated temperature regulating valve is composed of a control valve and a thermostat. According to the purpose, it is divided into heating type and cooling type.
Suitable for temperature control of non-corrosive liquid, gas and steam 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)
working principle
ZWT self-supporting temperature regulating valve can be divided into: heating temperature regulating valve, cooling temperature regulating valve, three-way confluence temperature regulating valve, three-way splitting temperature regulating valve. The working principle of the self-operated temperature regulating valve for different purposes is basically the same, and they all use the principle of thermal expansion, contraction and incompressibility of the liquid when the temperature-sensitive liquid is heated.
Below the heating temperature control valve, for example, in conjunction with a schematic diagram illustrating the principle of their work: the temperature sensor is inserted into the controlled medium, when the medium is controlled temperature, temperature of liquid expansion, the resistance against the spring biasing force, pushing the valve When the core moves downwards, the valve tends to close, thereby reducing the mass flow of the thermal medium; on the contrary, when the temperature of the controlled medium is lower than the set value, the temperature-sensitive liquid shrinks, and the spring reset pushes the valve core to open, increasing the mass flow of the thermal medium, so that The temperature of the controlled medium tends to rise. Circulate back and forth, so that the temperature of the controlled medium is always kept within the allowable range of the set temperature value.
The main features are as follows:
1. No external energy is needed, effectively saving energy;
2. High control precision, stable work, safe and reliable;
3. The temperature-sensitive liquid swells evenly, and is controlled by proportional adjustment;
4. The temperature setting operation is simple, and the adjustment is convenient;
5. Small size, light weight, easy installation.
