1. Before installing the valve body, check whether the valve and the mechanism are intact, confirm that all aspects of the valve are normal, and then install.When installing a smoke and fire prevention valve, the side of the valve body should be reserved, generally a net space greater than 350mm, which is convenient for regular action tests and inspections.
2. In the use, the action test should be performed regularly. It is recommended to conduct once every six months to one year.The running test includes the use number to open the valve to open or manually open.The valve body should have a separate support suspension to prevent the air duct from deforming at high temperature and affect the function of the valve.
3. When the valve body is installed on the ceiling, there should be inspection doors below.The general size should not be less than 45 × 45cm. If the conditions are limited, the ceiling inspection hole can also be reduced to 40 × 40cm.The protective kit of the circuit and remote control cables should be used in the D20 ordinary plastic tube.
4. Control the curved radius of the cable cover is greater than 250mm, and the curved is generally less than equal to 3 places.The size of the valve body (outlet) is on the wall, and the valve body should not be loaded, otherwise the valve will fail to deform after the squeezing.
