[0001] The utility model relates to the technical field of coal injection pipelines, in particular to a biased bell valve relief device. Background Art

[0002] At present, in the coal injection system used in the metallurgical industry, a control valve group is provided in the discharge pipe from the raw coal bin to the injection tank. The control valve group is mainly composed of upper and lower bell valves. Since the discharge pipe on the lower side of the lower bell valve is directly connected to the injection tank, and the normal working pressure in the injection tank is 800Kpa, when there is a leak in the lower bell valve, it will affect the normal injection of the injection tank. However, it is difficult to detect when the lower bell valve has a leak, which makes it impossible for the staff to discover it in time. For this reason, an offset bell valve relief device is proposed. Utility Model Content

The positioning connection mechanism includes a positioning ring 14, which is slidably inserted and installed in the vent pipe 1, and one end of the positioning ring 14 is in contact with the multi-layer sintered plate 15. The positioning ring 14 can be easily fixed to the multi-layer sintered plate 15.

[0023] A pipe connecting ring 10 is fixedly installed on the other end of the retaining ring 14. The pipe connecting ring 10 is set on the vent pipe 1. By setting an offset pipe on the discharge pipe from the raw coal bin to the injection tank, and then setting the offset pipe between the upper bell valve and the lower bell valve, and providing a regulating valve on the offset pipe, the vent pipe 1 can be installed on the offset pipe with the help of the pipe connecting ring 10. A connecting ring 13 is fixedly installed on the side wall of the vent pipe 1. A plurality of positioning screw holes 11 are provided on the side walls of the connecting ring 13 and the pipe connecting ring 10, and connecting bolts 12 are threadedly installed in the positioning screw holes 11. The setting of the connecting ring 13 can facilitate the installation and disassembly of the retaining ring 14 and the pipe connecting ring 10, thereby facilitating the maintenance and replacement of the multi-layer sintered plate 15.

[0024] A degassing hood 2 is fixedly installed at one end of the ventilation pipe 1, and an exhaust mechanism is provided at one end of the degassing hood 2. The exhaust mechanism includes an exhaust pipe 3. The exhaust pipe 3 is fixedly installed on the side wall of the degassing hood 2, and the exhaust pipe 3 is connected to the degassing hood 2.
