1. Before installing, check the shape of the valve and whether the operating mechanism is intact and whether the action is flexible. After confirming that all aspects of the valve are normal, install it.
2. The valve body should have a separate sling to prevent the duct from deforming at high temperature and affect the valve function.
3. When installed in the ceiling, there should be inspection doors under the observation and operating agency. The general size should not be less than 450*450mm. If the conditions are limited, the ceilings can also be reduced to 400*400mm.
4. Control the curved radius of the steel cables should not be less than 250mm, and the curved is generally less than 3.
5. The valve body is built in the wall size, and the valve body should not become loaders, otherwise the valve will fail after squeezing and deformation.
6. There is enough space near the fire prevention valve, which is conducive to installation and maintenance.
7. The fire prevention valve should be provided on the horizontal pipe section of the vertical air duct and the horizontal duct of each layer, but when the ventilation and air -conditioning system of each fire prevention partition of multiple buildings are independently set, the horizontal air duct and vertical general tube in the fire prevention partition areThere is no fire prevention valve at the junction;
8. The valve should be regularly shut down in the use before installation or after installation. It is recommended to perform it every six months to one year.
