Key Functions of Plastic Valve Testing Machines

Plastic valve testing machines are equipped with multiple functions to assess valve performance under different conditions. These include:

1. Pressure Resistance Testing

Purpose: Measures the valve’s ability to withstand internal and external pressure.

Process:

The valve is sealed in the testing chamber.

Controlled water, air, or hydraulic pressure is applied.

The machine monitors for any drops in pressure, indicating leaks or structural weaknesses.

Significance: Ensures the valve can handle operational stress without bursting or deforming.

2. Leakage Detection

Purpose: Identifies even the smallest leaks in the valve body or seals.

Process:

The valve is subjected to air or liquid pressure.

Highly sensitive sensors detect any escaping fluid or gas.

Leakage rates are measured and recorded.

Significance: Guarantees the valve’s sealing performance, preventing fluid loss in real-world use.

3. Flow Rate and Efficiency Testing

Purpose: Evaluates how effectively the valve regulates fluid flow.

Process:

The valve is connected to a flow testing system.

Fluid is passed through at varying pressures.

The machine records the flow rate, consistency, and pressure drops.

Significance: Ensures that the valve maintains optimal flow control under different operating conditions.

4. Torque and Rotation Force Testing

Purpose: Measures the force required to operate the valve.

Process:

The valve handle or actuator is rotated under controlled force.

Torque values are measured and compared to standards.

Significance: Verifies that the valve operates smoothly without excessive resistance.

5. Durability and Lifespan Testing

Purpose: Simulates long-term usage conditions to evaluate the valve’s longevity.

Process:

The valve undergoes repeated opening and closing cycles.

Pressure and flow variations are applied.

The machine logs performance over time.

Significance: Ensures the valve remains functional over its expected lifespan.
