Brief Description
Nou word meer en meer plekke beskerm deur gasbrandonderdrukkingstelsels, to ensure fire successfully, it requires the protection zone to remain closed when the extinguishing agent of the gas extinguishing system is released, op dieselfde tyd, needs to guarantee the integrity of doors, windows, and structures.
The pressure relief damper which we produce has another name “toestel vir drukontlading”, it has two styles, die een is vir elektriese werking en die ander vir meganiese werking.
It is installed on the wall in the protection zone, dit is normaalweg gesluit; wanneer of nadat die gasonderdrukkingstelsel begin optree, the pressure relief damper will be open automatically under a certain pressure caused by gas released, om die beskermingsgebied veilig te hou; en wanneer die druk tot 'n sekere waarde daal, die klep sal ook outomaties sluit.
Dit kan die digtheid van die beskermingsgebied verseker, voldoen aan die eis van brandonderdrukking, and as well to ensure that the protection area is safe.

- Product function: for various of gas fire suppression systems, including FM200, koolstofdioksied, IG541, IG100, NOVEC 1230 stelsels.
Working Principle of Pressure Relief Damper
Sy werkbeginsel is:
- Wanneer 'n brand ontstaan, the fire extinguishing system begins to act and release the suppression agent, and the pressure inside the protection zone starts to rise. Wanneer die druk na 'n vaste klep styg, the pressure relief mechanism will rapidly transfer the shutter from closed status to open status, to release the pressure in the protection area and to protect the structure.
- When the pressure drops under a set valve, the pressure relief mechanism reset, en die luik sluit.
installasie
Installation and Construction are as follows:
- eerste, choose the right model, volgens 'ontwerpspesifikasies vir brandblusstelsels'. we can calculate the area of the pressure relief valve that needs to be set in the protection area, and as per the area, we can know how to choose one more several valves from different models.
- tweede, om dit aan die muur te installeer, it should be installed on the exterior wall, en indien vir hfc-227ea brandonderdrukkingstelsel, according to China gas suppression standard GB50370-2004, dit moet op die muurlokaal van 2/3 hoog van die grond af.
Gebruik bevestigingsskroewe en gereedskap om dit aan die muur te plaas.
Vir meer inligting oor hoe om te installeer, kontak ons gerus vir meer inligting oor die installasie.
aandag
- Lees voor u dit installeer “Installasiehandleiding vir gasdrukontlasklep” versigtig, streng te installeer, to inspect, and to maintain as per our guide.
- Workers should be careful when carrying out installation work so as not to damage the surface of the pressure relief damper, and especially not to damage the motorized pressure relief valve.
- Never install it upside down, otherwise, it will not work.
- Tydens die installasieproses, versterk asseblief die beskerming van die klep se paneel.
- Moenie die toestel privaat oopmaak om die interne komponente aan te pas nie.
- After completing the installation work, we should test the motorized pressure relief valves by switching on the power supply; for mechanical devices (working without a power supply), we should test and see if their valve components are working properly.
- Na die installasie, every year we should inspect it, to ensure its reliability.
After-Sales Service
This product comes with a 1-year warranty time in case of non-manipulative conditions.
Within the warranty time, if have a quality default and quality problem, ons sal dit gratis vervang.
Verpakking
The main material of this product is made of high-quality steel, coated with white or silver-white paint, and some of them are equipped with electric devices inside.
daarom, in packing, we use a strong 5-layer brown carton box with polyfoam, die verpakking is dus baie geskik vir uitvoer. The packaging method is the standard export packaging form.
And as per the client’s requirement, we can add a fumigation wooden case as additional packing, to ensure the security of cargo.
Shipping
- Shipping time is about 10 days after finishing the production process.
- Choosing the right international logistics method and logistics company.
- For international shipments, you can choose between air, sea, or courier. because by air and by express are expensive, so we strongly suggest making the cargo by sea if you place the order.
OPMERKING: A pressure relief damper (pressure relief opening) normally works together with Brand onderdrukking Systems by installing the 2/3 hoogte vanaf die grondhefboom op die terrein (beskermingsone).
