The Faults Of The Valve

    The faults of the valve are also multiple and varied. If the intake and exhaust valves are not deformed and closed, the eczema in the dry room cannot be removed, so that the absolute humidity of the dry medium is always high. Or the failure of the Xu intake and exhaust valve will increase the measurement of the dry medium in the dry room. The way to check whether the intake and exhaust valve can be opened is to inspect the air intake and exhaust duct form of the dry room at the dry open-air table, or perhaps go directly to the roof of the dry room to observe the closed form of the intake and exhaust valve valves.

   The opening of the steam jet pipe valve failed. The steam jet pipe in the drying room is connected to continuously radiate steam, and the absolute value of the drying medium in the drying room is relatively high. The method of checking whether the steam jet valve can be ventilated is the opposite of the method of checking whether the heater valve can be ventilated. The failure of the heater valve of the drying facility prevents the steam from being delivered to the heater. The steam in the heater and steam pipeline will flow out quickly from the bypass valve, and the steam cannot be temporarily stored in the heater and steam pipeline to make it effective.

  The method of review is: After confirming that the by pass valve has been opened, open the repair valve of the steam trap again, wait a moment, and touch the return heat pipe at the input end of the bypass valve with your hand. If the proposal is very hot, Indicate the failure of the bypass valve switch; based on the sound of experience, if there is a sound of steam flowing through the bypass valve, it also indicates that the valve switch has a performance, and the maintenance should be stopped in time or replaced with a new valve. The heater valve of the wood drying facility is opened too large. If the heater valve has been opened, it may be that the heater valve has not been able to close, that is, the heater valve is ventilated.

   The way to check whether the heater valve can be truly opened is to: After opening the valve, wait a while and approach the steam pipe carelessly with your hands. The heater valve switch can perform abnormal tasks, that is, the switch is sensitive. If you claim that the steam pipe is very hot, your hands are hot when you touch it, or you can barely hold the pipe, indicate that the heater valve switch has failed, and the valve has not been deformed.
