Original Ingersoll Rand cold dryer expansion valve CD847676451001 dryer blower valve
The cold dryer expansion valve is a device used to regulate the refrigerant flow in the refrigeration system
Working principle
1. The basic principle of the cold dryer expansion valve is to control the refrigerant flow by adjusting the size of its own valve port.
2. There is an adjustable small hole or small-diameter pipe inside the cold dryer expansion valve, and the refrigerant flow is controlled by adjusting the size of this small hole
3. When the refrigerant pressure in the refrigeration system increases, the pressure acts on the piston inside the expansion valve, causing it to move downward.
4. The downward displacement of the piston will cause the valve port to open, thereby increasing the channel for the refrigerant to flow through the expansion valve and increasing the refrigerant flow
5. When the refrigerant pressure in the refrigeration system decreases, the piston will move upward due to the reduced pressure
6. The upward displacement of the piston causes the valve port to shrink, reducing the channel for the refrigerant to flow through the expansion valve and reducing the refrigerant flow.
7. In this way, by constantly adjusting the size of the valve orifice, the cold dryer expansion valve can control the flow of the refrigerant to maintain the stable operation of the refrigeration system. In short, the working principle of the cold dryer expansion valve is to control the flow of the refrigerant by adjusting the size of the valve orifice to adjust the refrigeration effect of the refrigeration system.
Product Features
1. Throttling effect
The expansion valve is an important component in the refrigeration system. Its main function is to change the medium-temperature and high-pressure liquid refrigerant into low-temperature and low-pressure wet steam through throttling, and then absorb heat in the evaporator to achieve the refrigeration effect.
2.Adjustment function
The expansion valve can control the flow of the valve according to the change in superheat at the end of the evaporator, thereby adjusting the flow of refrigerant, ensuring that the evaporator area is fully utilized, and avoiding underutilization of the evaporator area and cylinder knocking.
3. Strong adaptability
There are many types of expansion valves, including manual expansion valves, float expansion valves, and thermal expansion valves.
To sum up, the expansion valve of the cold dryer has significant advantages in throttling, adjustment and adaptability. Different types of expansion valves are suitable for different working conditions and equipment needs.
