Embodiment 1

[0072] Provide a model of DN150, IIA type pipeline detonation type flame arrester in service, using corrugated plate flame arrester as the flame arrester unit, where the design value of the flame arrester gap is 0.75±0.05mm, and the outer diameter of the flame arrester is 310mm. The overall thickness is 80mm, and the thickness of a single piece is 20mm.

[0073] see figure 2 , According to the above-mentioned evaluation method of flame arrester fire resistance performance, the reliability of the appearance of the flame arrester, the reliability of the internal structure of the flame arrester, and the detection of the key parameters of the flame arrester flame arrester are evaluated respectively. The reliability evaluation of the flame arrester's fire resistance performance is mainly based on the analysis of the results between the three, and the reliability parameter M=M1*M2*M3 of the flame arrester's fire resistance performance is obtained. When M3 ≥ 0.125 and M1, M2, M3 ar...

Embodiment 2

[0106] The qualitative evaluation method is adopted, and the 3oo2 method is used to judge whether the appearance of the flame arrester fails. For example, when more than two kinds of appearance deformation, corrosion and structural damage occur, the appearance of the flame arrester is judged to be invalid (the quantitative index of the appearance of the flame arrester is simplified). When the evaluation result is qualified, it can be recorded as 1, when it is not qualified, it is recorded as 0, and it is recorded as 0.5 when the judgment is not good.

[0107] For this flame arrester, the reliability evaluation of the appearance of the flame arrester and the reliability evaluation of the internal structure of the flame arrester are as described in Example 1, so M1=M2=1.

[0108] (23) Detection and evaluation of key parameters of flame arrester flame arrester flame arrester

[0109] Adopt the same method as Example 1 to obtain M3=0.5.

[0110] (24) Reliability evaluation of fla...

Embodiment 3

[0113] For the flame arrester in Example 1, the reliability of the appearance of the flame arrester, the reliability of the internal structure of the flame arrester, and the detection of the key parameters of the flame arrester flame arrester were evaluated.

[0114] The reliability evaluation of the appearance of the flame arrester and the reliability evaluation of the internal structure of the flame arrester are performed using the same method as in Embodiment 1, and will not be repeated here.

[0115] (33) Detection and evaluation of key parameters of flame arrester flame arrester flame arrester

[0116] For the inconvenience of dismantling the fire arrester unit, there are flame arresters that are difficult to install again after dismantling, and the gap value evaluation of the outer fire arrester unit can be used. In order to ensure the reliability of the data, the number of sampling points is doubled on the basis of the original suggestion. The sampling data is shown in ...

Abstract

The invention relates to the technical field of fire retardance safety, and discloses a fire retardance performance evaluation method and system of a flame arrester, and electronic equipment, and the method comprises the following steps: carrying out the appearance reliability evaluation of the flame arrester; evaluating the reliability of the internal structure of the flame arrester; fire arresting key parameter indexes of fire arresting units of the fire arresters are detected and evaluated; and based on the evaluation results of the flame arrester appearance reliability evaluation, the flame arrester flame retardance performance reliability evaluation and the flame arrester flame retardance unit flame retardance key parameter index detection evaluation, performing flame arrester flame retardance performance reliability evaluation. According to the technical scheme provided by the invention, a non-destructive method is adopted to test and evaluate the flame retardance of the flame arrester, so that the test efficiency is high, the test time is short, and stable operation of the device is ensured.

Description

technical field [0001] The invention relates to the technical field of fire resistance safety, in particular to a fire resistance performance evaluation method of a flame arrester, a system thereof, and electronic equipment. Background technique [0002] As a key facility to prevent flame propagation, the flame arrester has a decisive impact on the safety and reliability of the flame arrester. At present, the fire resistance performance of the flame arrester is mainly tested according to ISO16852 / USCG or GB13347, etc. If the corresponding requirements are met, the flame arrester performance is considered to be reliable. For example, ISO16852 for the steady-state detonation flame arrester needs to meet the requirements of 5 consecutive steady-state explosions. Only after the detonation and 5 consecutive deflagrations achieved effective fire resistance, the flame arrester was considered to meet the fire resistance performance requirements. The USCG requires that the detonation...
