Safety test

Test Background

Valves are responsible for flow control and fault isolation in the liquid-cooling system. Their sealing performance, pressure resistance, and electrical safety directly affect the operating safety of the system. Valve failure may lead to the inability to isolate leaks or cause misoperations.

Test Introduction

The safety experiment comprehensively verifies the safety performance of the valve under rated working conditions and abnormal conditions through the pressure test, leakage rate test, insulation resistance test, action response test and EMC test.

Testing Objectives

Verify the structural strength of the valve body under 1.5 times the working pressure

Detect the leakage rate in the closed state

Ensure electrical insulation and electromagnetic compatibility

Verify the action reliability in the fault mode

FAQ
Q: What is the required response time for the solenoid valve? A: Usually, it is required to be ≤1 second. For emergency shut-off valves, it needs to be ≤0.5 seconds to ensure rapid isolation under abnormal working conditions.
