Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of coal gas pipeline construction, in particular to a safety bracket for a coal gas pipeline valve and a mounting method thereof. BACKGROUND

[0002] The coal gas pipeline valve is a key control device installed in the coal gas (natural gas, liquefied petroleum gas, artificial gas, etc.) conveying pipeline system. Its core function is to control the flow of coal gas in the pipeline by opening, closing or adjusting the opening degree of the passage, and it is one of the core components to ensure the safe, stable and efficient operation of the gas system.

[0003] The existing installation method of the coal gas pipeline valve is mostly completed by making a pipe support to cooperate with the installation column. Welding operation is required under the coal gas pipeline and valve during construction, which has high safety risk. For example, the invention with the publication number CN 220957148 U discloses a coal gas pipeline fixing device, which comprises a mounting bottom plate, a plurality of mounting bases are arranged on the top surface of the mounting bottom plate, clamping rings are arranged on the top ends of the mounting bases, and the coal gas pipeline is clamped in the clamping rings; a detection pipe is arranged on one side of the top end of the coal gas pipeline, a buzzer is arranged on the top end of the detection pipe, a shunt pipe is arranged on the other side of the top end of the coal gas pipeline, and the shunt pipe is provided with a first electric valve; a second electric valve is arranged between the surface detection pipe and the shunt pipe. The utility model realizes the quick disassembly of the lower ring from the upper ring, thereby facilitating the maintenance or replacement of the coal gas pipeline by the staff; when leakage occurs in the pipeline, the explosion-proof valve in the detection pipe explodes, thereby triggering the opening of the first electric valve and the closing of the second electric valve and the opening of the buzzer, so that the coal gas is transported from the shunt pipe, and the buzzer reminds the surrounding people of the coal gas leakage, thereby ensuring personal safety.
