GB 15930-2007 "Fire Valves for Building Ventilation and Smoke Exhaust Systems" is a standard in the Chinese national standard that specifically regulates the technical requirements for fire valves used in building ventilation and smoke exhaust systems. The temperature sensor control test is used to verify the response of the fire valve under fire conditions to ensure that the shut-off procedure can be initiated quickly and reliably in the event of a fire. The following is a detailed introduction to the control test of the medium temperature sensor according to the GB 15930-2007 standard.
1.Background and significance of the trial:
The temperature sensor control test is an important test in the fire valve for building ventilation and smoke exhaust system, and its background is to ensure that the fire valve can respond quickly and accurately to temperature changes in the event of a fire, achieve timely closing, effectively isolate the fire source, and curb the spread of fire. This test is essential to ensure the safety of the building and improve the performance of the fire protection system.
2.Setting of test standards:
The GB 15930-2007 standard clarifies the technical requirements and methods for temperature sensor control testing. When formulating this test standard, the differences in the use environment and conditions of different fire valves are taken into account to ensure the comprehensiveness and applicability of the test. The standard stipulates the temperature requirements, test process, and evaluation of test results.
3.Setting of test conditions:
In the inductor control test, the setting of the test conditions is a key step. The standard specifies the environmental conditions required for the test, including the setting of temperature, to simulate the high temperature environment in the event of a fire. This helps to ensure that the test can be carried out in real-world use cases, increasing the authenticity and reliability of the test.
4.Test Method:
The GB 15930-2007 standard describes in detail the specific steps and methods of thermosensitive control testing. During the test, it is necessary to simulate the high temperature situation during the fire, so that the temperature sensor of the fire valve can quickly sense and respond to temperature changes. The test method needs to be precise and repeatable to ensure that the different fire valves can be tested in accordance with the requirements specified in the standard.
5.Evaluation of test results:
The standard specifies the method for evaluating the performance of fire valves based on the test results. Including whether the fire valve responds within the specified time, whether the closure is complete, whether there is air leakage, etc. These rating standards help to objectively evaluate the performance of fire valves and ensure that they are closed in time in the event of a fire.
6.Recording and reporting of test results:
The GB 15930-2007 standard requires that the test results should be recorded and reported in detail after the completion of the temperature sensor control test. This includes parameters monitored during the test, such as temperature changes, valve response times, etc. This helps manufacturers and users understand how fire valves perform under temperature sensor control.
Through the temperature sensor control test, the GB 15930-2007 standard provides scientific and reasonable methods and guidance for the design and production of fire valves for building ventilation and smoke exhaust systems. This helps to ensure that fire valves respond quickly and reliably in fire conditions, increasing the safety of the building in the event of a fire. The implementation of standards has promoted scientific and technological progress and product quality improvement in the construction field.
