Post, the sealing column side are connected with detector, and the detector is in close proximity to the central controller, the central authorities
Display screen is fixed with the top of controller, the concentration detector, the concentration detector side at the top of the sealing column, is fixed with
Flash appeal device is connected with, and the sealing column opposite side is connected with cylindrical seal ring, electricity is connected with front of the cylindrical seal ring
Magnet valve, is provided with earth leakage protective device above the magnetic valve.
In said structure, combustion gas carries out the conveying to user by the valve body via the magnetic valve, once pipeline is broken
Split when there is gas leakage, the detector carries out action first, after now the central controller receives action command,
The decentralization of actuating signal is proceeded by, now the stop valve is turned off at once, the magnetic valve also cuts off combustion gas at once
Conveying, once the concentration detector detect outer combustion gas concentration larger when, the flash appeal device sends appeal letter at once
Cease to local fire-fighting center, electric leakage occur so as to produce naked light in order to ensure this device now, the earth leakage protective device by when
Carving carries out protecting the electric leakage that the open circuit of this device occurs.
In order to further improve Detection results, with the ring flange by being welded to connect, the stop valve leads to the valve body
Cross and be bolted to the body top.
In order to further improve Detection results, the concentration inductor is fixed by screws at the top of the sealing column, institute
State central controller to electrically connect with the detector.
In order to further improve Detection results, the earth leakage protective device is electrically connected with the magnetic valve, the sealing column with
The magnetic valve is connected by the cylindrical seal ring.
In order to further improve Detection results, the concentration detector is electrically connected with the central controller, described urgent
Two's complementer is individually operated.
Beneficial effect is：This device can find gas leakage in the very first time, so as to also carry out to valve rapidly
Door closing, send alarm signal timely the advantages of.
