How to Install the Valve to Ensure the Efficient Operation of the Chiller?

The chiller is an indispensable cooling device in the industrial production process, providing cooling function for high-power laser equipment and water-cooled spindle equipment. At the same time, high-precision industrial chillers can also provide cooling solutions for the medical field, biological research and physical experiments. The equipment is refrigerated by vapor through compression, that is, using the principle analysis of heat absorption when different liquid refrigerants vaporize and heat release when vapor condenses to study refrigeration.

The failure rate of industrial chillers is low during operation. Even if there is a failure, it is usually a fault alarm such as an alarm of high room temperature and an alarm of high water flow. These are easy to remove and will not affect the production of the factory due to the occurrence of faults. Pay attention to the usual maintenance, the life of the chiller can be 5 to 10 years, and it can also reduce the cost of frequent replacement of refrigeration equipment.

Chiller equipment does not use any kind of hazardous chemicals or substances in its cooling process. The main liquid used by the equipment is water, which is safe for people and the environment. All its operations are environmentally friendly and do not produce any harmful gases or substances that damage the ecosystem.

In the refrigeration system, the main function of the valve is to control the flow and direction of the refrigerant. Since its daily use frequency is relatively high, it needs to be more careful during installation, so as to ensure its normal use and will not It affects the stability of the operation of the industrial chiller.

1. The valve should be installed in a position where it is easy to disassemble and maintain. When installing various valves, attention must be paid to the flow direction of the refrigerant and cannot be installed backwards.

2. When installing a flanged valve, the flange piece and the flange of the valve must be cushioned with high-pressure asbestos plate, and the thickness of the high-pressure asbestos plate should be determined according to the depth of the flange groove on the valve.

3. Install the globe valve so that the working fluid flows from the bottom of the valve to the top. When installing on a horizontal pipeline, the valve stem should be vertically upward or inclined at a certain angle, and the valve stem should not be downward. If the valve position is difficult to access or the position is high, the valve stem can be installed horizontally for the convenience of operation.

4. When installing the check valve, make sure that the valve core can be opened automatically. For the lift check valve, the center line of the spool should be perpendicular to the horizontal plane. For the swing check valve, the rotation of the valve core plate should be ensured, and the valve core plate must be installed in a horizontal position.

5. The safety valve should be directly installed on the globe valve at the outlet of the equipment, and the arrow on the valve body should be consistent with the flow direction of the working medium.

6. The solenoid valve must be installed horizontally at the outlet of the equipment, and must be installed in the position specified in the drawing. If the solenoid valve is installed in front of the throttle valve, a distance of at least 300mm should be maintained between the two.

7. The thermal expansion valve must also be installed horizontally. Pay attention to the inlet and outlet connections of the valve. Usually, there is a filter screen at the inlet end of the valve.
