About the product

Working principle of cooling valve

A cooling valve is a device used to control the flow of coolant, mainly used to regulate the temperature and flow rate of the cooling system to ensure that the engine or other equipment operates within the normal temperature range. The cooling valve controls the flow direction and flow rate of the coolant to prevent equipment from overheating or overcooling.

The working principle of different types of cooling valves

Refrigeration valve

Introduction: The basic structure of a refrigeration valve consists of a coil and a movable iron core located inside the coil. When the coil is energized, a magnetic field is generated to drive the iron core to move, thereby opening or closing the valve. The reset action of the valve is achieved by utilizing the gravity of the valve core and the elastic force of the spring installed on its top

Thermostat

Paraffin thermostat: When the cooling temperature is below the specified value, the fine paraffin in the thermostat sensing body becomes solid. The thermostat valve closes the passage between the engine and the radiator under the action of the spring, and the coolant returns to the engine through the water pump for small circulation. When the coolant temperature reaches the specified value, the paraffin begins to melt, increasing in volume and compressing the rubber tube, causing the push rod to exert an upward thrust on the valve, opening the valve and performing a large cycle. ‌

Electronic thermostat: The working principle is similar to that of a paraffin thermostat, but electronic sensors are used instead of paraffin to sense temperature changes, thereby more accurately controlling the circulation of coolant

Application scenarios and precautions of cooling valves

In practical applications, cooling valves are widely used in situations that require temperature control, such as automobiles, industrial equipment, and air conditioning systems. For example, in a car cooling system, a thermostat controls the flow and direction of coolant to prevent the engine from overheating or overcooling. In addition, it is necessary to pay attention to regular inspection and maintenance when using cooling valves to ensure their normal operation and avoid equipment damage caused by cooling system failures. ‌
