The new house is being renovated to curb floor heating. After pressing, it seems that all the valves are closed. Is this in line with the operating procedures? Online emergency

The new house is being renovated, and the residential property is suppressed by floor heating. After the fire is put out, all valves are closed, which is in line with the operating procedures.

The purpose of floor heating suppression is to check the tightness and pressure stability of the floor heating system. In the process of compaction, slowly inject water and pay attention to the gas in the pipeline. After being filled with water, conduct water tightness inspection and pressure test. In the process of pressure test, manual pressurization is needed. After the pressure increases to the specified test force, it is necessary to stop and stabilize the pressure for a period of time, observe whether the pressure gauge drops and judge whether it leaks. If no water leakage is found after stabilizing the voltage for a period of time, the floor heating system can be considered qualified.

After the pressing is completed, the pressure shall be released and the corresponding pressing records shall be kept on file. It is normal to close all valves after pressing, which can ensure the safety and stability of the floor heating system. In case of abnormal pressure or serious pressure drop, contact the floor heating construction personnel in time to find out the fault and solve it as soon as possible.
