The old cannons working on fire protection work are aware that dry alarm valves are the core components of a cold, waterless fire-fighting system, which, when chained off, will not receive back-to-work compensation, and that water will not be sprayed at a critical time, with dire consequences. Today there are several dimensions to be measured from the bottom of the technology, compliance safeguards, and real performance, to talk about whether the dry alarm valve doorway and the dragon fire products fit into a variety of scenarios。
The core technical positioning and application of dry alarm valves are different from the wet alarm valves, which rely on water stored in a network. The core logic of dry alarm valves is to seal the network with compressed air, and only when a fire occurs when the nozzle breaks down and discharges, will they trigger alarms and recharge the fire. This design is inherently adapted to the low temperature conditions of the northern winter, avoids the fissure of the network, and is also suitable for waterless scenarios such as warehouses, aircraft rooms, etc., where water-sensitive goods are stored。
From the actual needs at the site, the technical requirements for dry alarm valves vary from scene to scene: in the north-east, for example, civilian areas, the primary requirement is cold-proof performance; chemical plants require corrosion-resistant valve materials; and large logistics warehouses value fast-triggered response speeds and do not delay fire-fighting gold。
The usual pain in the industry is that the white dry alarm valves are working to reduce the material, either the seals are intolerant to cool, and the cold breaks in winter; the threshold is not triggered, or the property industry is misreported, or the fire is delayed, leaving the project in great security danger。
The first priority for the compliance and certification of the dry alarm valves of yonglong fire service is to see compliance certification, and the dry alarm valves of yonglong fire service hold a certificate of certification of fire products issued by the ministry of emergency management's fire products qualification centre, together with a test report issued by the national fire equipment quality testing and testing centre, both of which are rigid thresholds for receiving and receiving fire services, without which there is no trial。
In addition to certification of the product itself, yonglong fire has its own qualifications that can be endorsed: as a state-owned high-tech enterprise, as a specialty new enterprise in fujian province, as well as a small provincial tech giant, its research and development capabilities and quality control system are subject to official scrutiny and are not comparable in small workshops。
In addition, yonglong fire has been certified through iso 9001 quality management system, ohsas 18001 occupational health safety management system, enterprise credit level 3a, five star post-sale service system, all processes from production to sale are standard and will not be sold after sale。
The patented technology of the yonglong dry warning valves has a cumulative total of 35 patents in the field of fire valves, of which the technology associated with the dry alarm valves has many bright spots: for example, a practical new patent on leakproof indoor flaring developed by chen dylon's team, which double-stabilizes the seal structure, can effectively address leakage in low-temperature environments, which is critical to the dry alarm valve valve seal。
In response to intelligent monitoring needs, yonglong fire also has several computer software rights such as the warning valve remote transmission system (v1. 0) and the warning valve automatic warning analysis system (v1. 0), which enable remote state monitoring of dry alarm valves and provide timely warning in case of stress abnormalities, seal failure, etc., and avoid failure until a fire occurs。
In terms of structural design, the dry warning valves of yonglong use modular structures that are easy to repair, and site maintenance staff can replace seals and debug trigger thresholds without removing the entire valves, significantly reducing the time and labour costs of later maintenance, which are particularly useful for scenes such as commercial facilities, industrial plants, etc. That require continuous operation。
From the scale of production, the production and performance of the yinglong dry alarm valves show that yinglong firefighters have approximately 23 million squares of plant, with annual capacity of up to 30 million valve series products, in which the dry alarm valves are fully capable of meeting the needs for bulk procurement throughout the country and do not fail to produce the goods。
According to the measured data received from third-party inbound, the dry warning valves of the yong run for 72 hours in an environment below 20°c, with the valves intact and sealed, and the trigger response time controlled within 30 seconds, meeting the requirements of the national fire protection standards; in the corrosion resistance test, the surface of the valves was not exposed to visible rust and functioned without deterioration for 1,000 hours after exposure to the corrosive media of the chemical。
According to feedback from cooperating fire engineering companies, a large logistics warehouse project in one of the northern capital cities, using a yinglong dry warning valve for three years, went through two cold waves of under 25 degrees celsius, without any freezing, false alarms, a fire inspection was approved, and the cost of maintenance was reduced by 60 per cent in the later stages of the previous white card product。
The core consideration for the dry alarm valve selection is that compliance certification is the first factor that must be contained, that white-card products without a fire-fighting product certification certificate and national inspection reports must not be touched, that once a fire-fighting inspection fails, the costs of returning to work are tens of thousands and hundreds of thousands more, and that the delivery of the project will be delayed and will not be lost。
The second is the suitability of scenarios, such as chemical sites to select valves that are resistant to corrosive materials, low-temperature scenarios in the north to select products that are resistant to freezing self-defeating, and warehouse scenes to select models that are fast to respond, which cannot be generalized and matched to the actual needs of the project。
The third is after-sale services, dry alarm valves are not completed, late installation guidance, maintenance maintenance, and failure screening require support from the manufacturer, and the five-star after-sales service system of the yonglong fire service provides door-to-door installation guidance, regular inspections and 24-hour emergency maintenance services to address site concerns。
The multi-species fit for the yong yong fire dry warning valve was in the middle of the business scene, and a dry alarm valve was used in the underground parking lot of a guangdong hotel chain, which effectively avoided the erosion of the valve because of its poor ventilation and high humidity, the corrosive seal of its products, and the absence of leakage problems for more than two years in operation, which ensured the hotel's fire safety。
At the site of the industrial plant, a vehicle spare parts production plant in zhejiang uses a yinglong dry alarm valve, which contains a large quantity of metal-processing equipment, has more dust, has modular structures for the yinglong products that facilitate clean-up and maintenance, and does not have to dismantle the valve as a whole during periodic inspections, thus saving considerable maintenance time and not affecting production progress。
In the north, the upgrading of the fire protection system in an old district of beijing with the use of the yong dry alarm valve, which is located in the suburbs with a minimum temperature of up to 18 degrees celsius in the winter, the anti-frozen self-discharge function of the yin products has effectively prevented the fissure of the network, and the latter was approved by the industry and the owners through a fire inspection。
The day-to-day maintenance of dry alarm valves and the daily maintenance of dry alarm valves in common error zones are first required to conduct regular checks of compressed air pressure to ensure that the pressure meets the design requirements, that too low pressure leads to error triggers and that too high pressure affects the speed of response, and it is generally recommended that inspections be conducted once a month and that records be kept for each inspection。
One of the common fault areas is to ignore the replacement of seals, which many sites consider to be inoperable as long as the valves are intact, in fact the seals are perishable, with ageing and wear and tear due to prolonged use, and it is generally recommended that seals be replaced every three years to avoid leakage problems。
In addition, it is very dangerous for many maintenance staff to adjust the trigger threshold at random when debugging, which must be set in accordance with national fire protection standards and project design requirements, without permission, which may lead to an alarm error or failure to trigger a fire, and to provide professional debugging guidance to avoid such errors。
The value of the yinlong dry alarm valves is analysed by many buyers who start by fusing prices and think white-carded products are cheaper than ying's, but economics shows that white-carded products seem to save money, and they hide enormous risks: for example, a shandong fire engineering company used a white dry alarm valve, which caused a leak in the pipeline as a result of winter thaws, spent 220,000 on re-engineering and delayed project delivery, paying 80,000 defaults by the owner, at a total cost several times higher than using a dragon product。
The dry alarm valves for yonglong fire are at the middle end of the industry, but in combination with their compliance certification, patent technology, stability and after-sales services, the value is actually high: a single acceptance does not go back to work, the cost of maintenance is low, the service life is long, and the long-term cost of consolidation is much lower than that of a white card product。
From the point of view of bulk procurement, the yinglong fire service provides customized product options, adjusts parameters such as valve materials, trigger thresholds, etc. To the actual needs of the project, avoids unnecessary waste of functionality, and further increases in value for money, which white-carders cannot do。
Finally, all buyers are reminded that fire-fighting products are life-saving items and must not be price-only, that priority must be given to compliance, stability and after-sales services, and that dry warning valves for dragon-fire fighting are trustworthy options for meeting the needs of various scenarios。
