Abstract
The invention discloses a self-closing type water drain apparatus for gas and a service method of the self-closing type water drain apparatus, which belong to the technical field of drainage facilities for gas pipelines. The self-closing type water drain apparatus for gas comprises a shell, an inner chamber plate, an upper cover plate, a lower cover plate, a high-pressure working pipe, a medium-pressure working pipe, a low-pressure working pipe, a float ball, a connecting rod, a valve port, a sealing ball, a magnetic-induction transmitter, an electromagnetic receiver, an alarm lamp, an overflow pipe, a blowdown valve, a drain valve, a vent hole and a screwed plug. After the self-closing type water drain apparatus for gas is mounted, water is filled into the self-closing type water drain apparatus until the water is fully filled and flows out, a valve of a gas pipeline is opened, the self-closing type water drain apparatus starts to work, and the gas is effectively sealed by the aid of a principle of water level difference. When the pressure of the gas is excessive or water level in the water drain apparatus is lowered to a certain position or the problem of water leakage of the inner chamber plate is caused, a magnetic induction system of the low-pressure working pipe starts to act. When in abnormal conditions, the alarm lamp starts to alarm. The self-closing type water drain apparatus for the gas solves the difficult problem of leakage of overpressure gas to cause safety accidents easily by the aid of a magnetic-induction alarm system, and operability of tour-inspection operators in terms of daily tour inspection is enhanced.
