Overview of the imported electric temperature control valve. The biggest features of this valve are simple structure, easy operation, wide temperature range selection, fast response time, reliable sealing performance, and can be adjusted at will during operation and only requires Ordinary power supply, developed by Germany's Olschen R, uses the energy of the adjusted medium to directly automatically adjust and control the temperature of steam, hot gas, hot oil, gas and other media. It can also be used to prevent overheating or heat exchange situations. It consists of components such as control valve actuator sensor and capillary tube. It is divided into heating type and cooling type according to usage. Electric temperature control valve is suitable for larger diameter and thermal oil control. Electric temperature control valve is mainly suitable for temperature control of liquid gas and steam in various cooling systems. When the temperature of the controlled medium rises, the control valve closes the heating type. When the temperature of the controlled medium rises, the control valve opens the cooling type.
Structural Principle of Electric Temperature Control Valve
The control valve consists of three parts: the main valve intelligent actuator and the sensor. According to the user's needs, there are two structures: heating type and cooling type.
Before the electric temperature regulating valve works, the main valve core is in a half-open position and the sensor is in a natural state. Connect the power supply and the main valve core is fully opened. The medium flows into the main valve body in the direction of the arrow and heats the heat storage tank through the valve core. When the temperature rises to the corresponding set value, the sensor generates a corresponding linear signal and inputs it into the integrated intelligent actuator, which then drives the valve stem and valve core to move, closing the main valve core to stop heating. When the temperature is lower than the set value, the sensor generates a linear signal and inputs it into the actuator, which drives the valve core to gradually open, causing the medium to flow into the heat storage tank according to parabolic characteristics and heat until the set value. In this way, the controlled medium is always controlled within the set temperature range, thereby achieving the purpose of temperature control.
Features of imported electric temperature regulating valve
High control precision, stable operation, safe and reliable.
The temperature-sensing liquid expands evenly and is controlled by proportional adjustment.
The temperature control setting is outside the actuator. It is very convenient to set the temperature. The temperature setting operation is simple and easy to adjust. The digital display of the measured temperature is simple, intuitive and clear.
It is simple and easy to use the potentiometer to adjust the sensitivity of the starting point of the working zero point and the end point of the full stroke. Small size, light weight, easy to install.
The key component controller of the regulating actuator adopts the most advanced hybrid integrated circuit. After aging treatment, it is sealed and cast with resin. It is box-shaped, moisture-proof and shock-proof, small in size and high in reliability. The actuator has three protection functions: overload protection, temperature protection and compression spring to ensure tight closing of the valve.
Reasonably designed upper and lower electrical limit functions and weak current control are safe and durable.
The mechanical structure is sturdy and compact, and the online installation, adjustment and maintenance are very simple.
The nominal diameter of the imported electric temperature regulating valve ranges from to, the nominal pressure ranges from Fluoride flexible graphite, push rod bushing, gasket rubber asbestos board r asbestos wound gasket, bellows
