Working Principle and Structure:
The constant temperature valve is installed in the oil circulation pipeline. It contains a temperature sensing element (such as wax coating or bimetallic strip) and a valve mechanism. When the oil temperature is low, the valve closes the channel for the oil to flow to the cooler, allowing the oil to directly return to the main unit (achieving rapid temperature rise); when the temperature reaches the set value (usually around 70℃), the temperature sensing element expands and pushes the valve open, allowing the oil to enter the cooler for cooling before circulating again, thereby maintaining the oil temperature within the ideal range.
Core Advantages of Original Assembly Parts:
The original factory constant temperature valve has the following features:
Precise Temperature Control: The opening temperature error is ≤ ±2℃, ensuring that the oil operates within the optimal viscosity range, reducing the wear of the main unit and energy consumption;
Oil-resistant and High Temperature-resistant: The valve body is made of cast iron or high-strength alloy, and the internal sealing components are selected from materials resistant to oil and anti-aging, capable of withstanding short-term high temperatures of 120℃ or above;
Quick Response: The valve action time when temperature changes is ≤ 10 seconds, avoiding excessive temperature fluctuations;
Perfect Compatibility: The interface size and flow design match the model, ensuring reasonable oil circulation resistance and not affecting the pressure of the lubrication system.
Key Points for Model Matching:
The specifications of the constant temperature valve are related to the oil flow of the air compressor, the design of the cooling system, and vary for different series (such as GA, G, ZR, etc.) and power models. When purchasing, please provide:
The specific model of the air compressor (such as GA22, GA55VSD) and the factory serial number;
The installation position of the constant temperature valve (such as the inlet or outlet pipe of the oil cooler);
The part number of the old valve (usually marked on the valve body surface).
