Description

Technical Field

[0001] This application belongs to the field of fire protection operation and maintenance technology, specifically, it relates to a comprehensive operation and maintenance management system. Background Technology

[0002] Fire valves are control components of building fire protection water supply systems. Their sealing performance directly affects the operational reliability of the fire protection system under fire conditions. Rubber gaskets are vulnerable components of fire valves, and aging, cracking, and performance degradation of the gaskets are among the main causes of leakage and malfunction of fire valves.

[0003] The current industry practice for the operation and maintenance management and aging prediction of fire valve sealing gaskets is to replace them at fixed intervals. The common practice is to replace gaskets after 5 years and scrap valves after 10 years. However, most of these practices do not fully consider the differences in gasket material, installation environment, actual operating conditions and actual aging status.

[0004] This model has two main drawbacks. First, it can lead to over-maintenance, causing a large number of gaskets that are still in normal working order to be replaced prematurely, increasing unnecessary maintenance costs. Second, it makes it difficult to detect risks in a timely manner for gaskets that experience premature performance degradation under harsh working conditions, which can easily leave fire safety hazards.

[0046] When 30%≤ When the percentage is less than 60%, it is determined that the inspection level should be increased, the inspection cycle should be shortened, and additional sealing performance testing should be conducted.

[0047] When 60%≤ If the gasket is less than 90%, it is determined to be a gasket replacement requirement, and maintenance personnel will be arranged to replace the sealing gasket.

[0048] when When the rate is ≥90%, it is determined to be an emergency replacement level, and the target fire valve should be replaced immediately.

[0049] Furthermore, the boundary scene correction and iterative optimization module includes a boundary scene correction sub-module and a model optimization sub-module connected by sequential signals;

[0050] The boundary scene correction submodule is used to supplement specific correction coefficients and correct prediction biases for extreme boundary scenes with high salt spray, high corrosion, and high opening and closing frequency.

The material, installation time, and installation environment parameters of the new gasket are pushed to the aging calculation engine module to automatically establish a new baseline for aging prediction. At the same time, the maintenance records are synchronously connected to the fire protection facility maintenance management platform.

[0053] Compared to existing technologies, the beneficial effects of this application are as follows:

[0054] This application systematically incorporates aging influencing factors such as temperature, UV, ozone, humidity, installation environment, opening and closing frequency, and media properties by using a multi-factor coupled regional meteorological coefficient, installation location coefficient, and boundary scenario correction coefficient. This allows it to better adapt to the operation and maintenance needs of fire valves under different climate zones, installation environments, and operating conditions.

It is used to correct the boundary scene prediction deviation, iteratively optimize the aging coefficient, and update it back to the regional aging database module.

[0067] The current fire protection system uses Z41X-16Q type fire-specific rising stem resilient seated gate valve, with a nominal pressure of 1.6MPa, DN150, and the sealing gasket is a national standard EPDM ethylene propylene diene monomer rubber gasket of the same batch, with a thickness of 3mm and a Shore A hardness of 60±5HA. It has been in use for 6 years, with 8 opening and closing times per year, and the conveying medium is normal temperature fire-fighting clean water.

[0068] The testing equipment used in this embodiment includes a QLH-500 hot air aging test chamber, a ZW-P fluorescent ultraviolet aging test chamber, a QL-100 ozone aging test chamber, a hydraulic compression set fixture, an LX-A type Shore hardness tester, a Zeiss EVO18 scanning electron microscope, and a YWX-250 salt spray test chamber.

[0069] The test subjects were EPDM gasket samples of the same batch and specifications as the valves on site, totaling 30 groups, with 5 parallel samples in each group. Accelerated aging tests were conducted for 4 types of installation scenarios, and the test parameters were set as follows:

[0070] 1. Outdoor sunlit scene, circulating temperature -10℃~60℃, diurnal temperature difference 20℃, average daily high temperature duration 8h; UV irradiance 0.89W / m², average daily irradiation duration 12h; ozone concentration 60pphm; relative humidity 40%~80% cycle; gasket compression rate 25%; test cycle 720h.

[0071] 2.

[0072] 3. Underground pump room scenario, constant temperature 20℃, no temperature difference; no UV radiation; ozone concentration 20pphm; constant relative humidity 60%; gasket compression rate 25%; test cycle 720h.

[0073] 4. Indoor enclosed machine room setting, constant temperature 25℃, no temperature difference; no UV radiation; ozone concentration 15pphm; constant relative humidity 50%; gasket compression rate 25%; test cycle 720h.

[0074] During the experiment, samples were taken every 120 hours to test the Shore A hardness, compression set, and surface morphology of the outer and inner rings of the gasket samples. The final baseline data were collected. After the same period of aging, the hardness change rate of the outer ring of the gasket in the underground pump room scenario was 8.2%, and the hardness change rate of the inner ring was 4.3%; the hardness change rate of the outer ring of the gasket in the outdoor sun-facing scenario was 27.6%, and the hardness change rate of the inner ring was 14.1%. The failure patterns of 30 groups of samples were analyzed. 94% of the samples failed starting from the outer ring of the gasket, and the average aging rate of the outer ring was 1.86 times that of the inner ring.

[0075] Based on the accelerated aging test data mentioned above, the standardization calibration of all coefficients was completed, such as the material coefficient. Calibration based on EPDM =1.0; NBR calibration =1.2; Fluororubber calibration =0.7; Installation location coefficient is Calibration is performed using the outdoor backlit side as a reference. =1.0; Outdoor sun-facing surface =1.3; Underground pump room =0.7; Indoor enclosed machine room =0.6; Nonlinear aging index n is calibrated for underground / indoor scenes n=1.1; for outdoor backlit scenes n=1.2; for outdoor frontlit scenes n=1.3;

[0076] Based on the outer ring contributing 80% to the seal failure and the inner ring 20%, combined with a weighting coefficient of 1.3 for the outer ring and 0.7 for the inner ring, the fixed weighting constant is calculated to be 0.8 × 1.3 + 0.2 × 0.7 = 1.18; the scenario correction coefficient is for an annual opening and closing frequency of ≤12 times. =1.0; 12-50 opening and closing times per year. =1.1; Annual start / stop > 50 times, =1.2; Clear water medium =1.0; seawater or high salt spray medium =1.2; weakly corrosive medium =1.3.

[0077] Specifically, at this point, the overall aging degree of the seal is defined. =100%, corresponding to the gasket reaching any of the following critical states: compression set ≥50%; Shore A hardness change ≥15HA; surface penetrating cracks; leakage rate >0.01MPa / min under 1.6MPa water pressure for 5 minutes.

[0078] Rated reference life Under standard operating conditions, EPDM gaskets have a TF of 10 years; NBR gaskets =8 years; Fluororubber gasket =15 years.

[0079] Operation and maintenance level boundary thresholds are divided into the following four levels:

[0080] Normal operation and maintenance level, at this time <30%, perform quarterly routine inspections;

[0081] Increase the inspection level, at which point 30% ≤ If the seal is less than 60%, monthly inspections should be conducted, and a sealing pressure test should be performed every six months.

[0082] Gasket replacement grade, at which point 60% ≤ If the seal is less than 90%, replace the gasket within 30 days.

[0083] Emergency change of level, at this time If the failure rate is ≥90%, immediately stop using the valve and replace it.

[0084] The regional meteorological coefficient database submodule connects to the public database of the meteorological data center to obtain the average meteorological data of all districts and counties in China for the past 10 years. Based on the annual average temperature of 25℃, annual UV radiation of 3000MJ / m², annual average ozone concentration of 0.05mg / m³, and annual average relative humidity of 60%, the regional meteorological coefficients are calculated using a dimensionless weighted algorithm.

[0094] The parameter compliance verification submodule verifies the integrity, format compliance, and numerical rationality of parameters. After the verification is passed, a standardized compliant parameter package is generated and pushed to the aging calculation engine module.

[0095] The coefficient auto-retrieval submodule in the aging calculation engine module retrieves the corresponding coefficients based on the compliance parameter package. =1.0、 = 0.89、 =0.7、 =1.0、 =1.0, n=1.1, =10 years;

[0096] The formula for calculating the overall aging degree of the seal is:

[0097]

[0098] The final calculation is ≈5.28%;

[0099] Meanwhile, the aging degree of the outer ring of the gasket was calculated to be DO≈5.81% and the aging degree of the inner ring to be DI≈3.13% respectively;

[0100] The formula for calculating the remaining seal life is:

[0101]

[0102] The final calculation is ≈9.38 years;

[0103] Operation and maintenance level determination is based on =5.28%, which is considered a normal operation and maintenance level.

[0104] The output generates a standardized fire valve gasket aging prediction report, which includes basic valve information, aging prediction results, trend prediction curves, compliance recommendations, and supports data export.

[0105] Then, a standardized inspection work order of the corresponding level is sent out, which clarifies the inspection content, acceptance standards and completion time limit;

[0106] It also updates the valve electronic maintenance log simultaneously, automatically resets the service life after gasket replacement, and establishes a full life cycle tracking file for new gaskets.

[0107] Example 2: This example applies to an outdoor fire hydrant network in a coastal chemical industrial park. The target valve is a D341X-16Q type fire-fighting flange butterfly valve, DN150, nominal pressure 1.6MPa, with NBR nitrile rubber gasket. It has been in use for 9 years, installed outdoors on the sunlit side in a coastal high-salt-fog environment, with an average of 25 opening and closing times per year. The transported medium is ambient temperature fire-fighting water.

[0108] Accelerated aging tests under high salt spray conditions were conducted using the YWX-250 salt spray test chamber to calibrate the correction factor for high salt spray conditions along the coast. =1.2;

[0109] The regional coefficient is the meteorological coefficient of a specific location. =1.01;

[0110] Then, complete the target valve parameter input and compliance verification, and generate a compliance parameter package;

[0111] The coefficients are retrieved automatically. =1.2、 =1.01、 =1.3、 =1.1、 =1.2, n=1.3, =8 years;

[0112] Substituting the aging degree into the formula, we can calculate... ≈55.25%;

[0113] The remaining lifespan is calculated as follows ≈3.58 years;

[0114] Based on the condition that 30%≤55.25%<60%, the inspection level is determined to be enhanced, and a maintenance strategy of monthly inspection and sealing pressure test every 3 months is implemented.
