Fire Resistance Tester for Valve, ISO 10497

Product Description

Fire Resistance Tester for Valve

Introduction:

This product is designed and developed according to ISO10497 and JB/T6899 standards. It uses burners to simulate fire scenarios, and conducts fire resistance tests under load conditions on valve components for ships and similar purposes under internal pressure conditions.

Reference Standard:

Ø ISO 10497 Testing of valves — Fire type-testing requirements

Ø JB/T 6899-1993 valve fire resistance test

Main Feature

1. Combustion box size: 2,500(W)×1,500(D)×3,000(H)mm. It is made of stainless steel plate, lined with stainless steel bracket.

2. Equipped with a large observation window to observe the internal test status.

3. All internal tools are made of stainless steel.

4. The cross-sectional area of the burner is at least: 80mm×350mm, totaling six pieces. During the test, the number of burners can be selected according to the size of the sample. There are at least 20 fan-shaped nozzle burners per square decimeter.

5. Equipped with burner lifting device to adjust the distance from the burner to the sample.

6. Smoke exhaust pipe size Ø400 x 1,000(L) mm. The top is equipped with a diffuser.

7. Each burner unit is equipped with a Venturi mixer to fully mix the gas and air to ensure the flame temperature.

8. The temperature measuring block is made of 38mm cube carbon steel, with an armored thermocouple embedded in it.

9. Stainless steel exhaust pipe and related accessories.

10. Imported dual flow meters: air flow and gas flow meters and control valves.

11. Imported brand pressure gauges and pressure regulating valves.

12. The bottom of the combustion box is equipped with a drip tray for burning residues and a drainage filter system.

13. The drainage system and throttle valve are made of stainless steel.

14. The exhaust fan is a stepless variable speed exhaust, which guides the airflow to produce a directional flame.

15. The position of the burner can be moved, which meets the test of different types of valves.

16. Equipped with water level gauge and measuring cylinder, it is convenient to observe and test valve leakage.

17. Configure high-pressure pipelines and valve body modules to meet high- pressure testing and safety requirements.

Testing system

1. Use a booster pump to fill the test valve with a maximum pressure of 31.9MPa.

2. The pressure relief valve is set to 20°C which is 1.5 times the working pressure to prevent the test valve body from rupturing caused by vaporization and pressure increase.

3. Imported armored thermocouple can monitor the temperature of the fire zone to 760℃ within 2 minutes.

4. The average temperature of the thermocouple in the temperature measuring block reaches 650°C within 15 minutes.

5. DPT can accurately test the system pressure. Test accuracy: ±0.01 MPa.

6. Timing: 0～9999±0.1 seconds.

7. The test time can be set, the default is 30 minutes.

8. After the test, check the water level of the container and the drain pan to calculate the leakage of the test valve.

Control systerm

1. Computer control system, Labview test special software.

2. The test realizes intelligent control: automatic ignition and automatic flame adjustment. The test report is automatically saved and can be retrieved and printed freely.

3. Use laboratory development tools to design a simple graphical interface (GUI) operating environment for operators.

4. Real-time recording and saving of test data through automated control logic to facilitate test repeatability comparison.

5. Provide data analysis and test report format to meet customer requirements.

6. With replaceable burner, it can meet the test methods of three fire-fighting accessories.

7. The imported flow controller can automatically control gas and air, and the flow test range: 0-100L/min.
