Abstract
The utility model relates to a safe diffusing system of a fuel gas pipeline. The safe diffusing system comprises a fuel gas main pipe, a fuel gas branch pipe, and a connecting pipe connected with an indoor fuel gas device of a user. The fuel gas main pipe is connected with the fuel gas branch pipe via a control valve 1; the fuel gas branch pipe is connected with the connecting pipe via a control valve 2; a diffusing pipe 1 leaded to atmosphere is connected with the fuel gas branch pipe arranged between the control valve 1 and the control valve 2; a control valve 3 is arranged on the diffusing pipe 1; the connecting pipe is connected with the diffusing pipe 1 via a diffusing pipe 2; the diffusing pipe 2 and a connecting end of the diffusing pipe 1 are arranged after the control valve 3, i.e., after an air outlet of the control valve 3; and a control valve 4 is arranged on the diffusing pipe 2. The safe diffusing system is installed on the fuel gas pipeline. By firstly closing the control valve 1 and the control valve 2 and opening the control valve 3 and the control valve 4 to evacuating remained gas in the connecting pipe and the gas branch pipe, potential safety hazards can be eliminated, and the fuel gas pipeline can be repaired and accidents can be prevented as required. The safe diffusing system is simple in structure, safe and reliable.
Description
Technical field
The utility model relates to the safe diffusion system of a kind of gas pipeline.
Background technique
Along with the extensive use of combustion gas, it is particularly important that the safety problem of combustion gas seems.It is all, by pipeline, the combustion gas of gas station is transported to gas user that most combustion gas is used.Generally enter one or many home fuel gas user the indoor fuel gas equipment connection with user by combustion gas arm combustion gas supervisor.In order to use, easy to maintenance, conventionally between combustion gas supervisor and combustion gas arm, control valve is set, between user's indoor fuel gas equipment and combustion gas arm, be connected by connecting tube, connecting tube is provided with control valve.In maintenance, processing accident etc. in particular cases, need to close control valve between combustion gas supervisor and combustion gas arm and the control valve on connecting tube, owing to being full of combustion gas between above-mentioned two control valves, bring potential safety hazard to maintenance, processing accident etc.
Summary of the invention
Problem to be solved in the utility model is to provide the safe diffusion system of a kind of gas pipeline, and this system, for gas pipeline, can be got rid of the remaining combustion gas in pipeline, eliminates the potential safety hazard of maintenance, the accident treatment etc. of gas pipeline.
The technological scheme that the utility model provides is: the safe diffusion system of a kind of gas pipeline, comprise combustion gas supervisor, combustion gas arm and with the connecting tube of user's indoor fuel gas equipment connection, combustion gas supervisor be connected with combustion gas arm by control valve one, combustion gas arm is connected with connecting tube by control valve two, on the combustion gas arm between control valve one and control valve two, be connected with the exhaust stack one towards atmosphere, exhaust stack one is provided with control valve three, connecting tube is connected by exhaust stack two with exhaust stack one, exhaust stack two be positioned at control valve three with the connecting end of exhaust stack one after (after being positioned at the air outlet of control valve three), exhaust stack two is provided with control valve four.
Described exhaust stack one is provided with detecting tube, is connected with ball valve on detecting tube, for detection of the leakage of control valve three solenoid valves.
The outlet end of described exhaust stack one is provided with flame trap.
The utility model is installed for gas pipeline, needing repairing or when processing accident, first closed control valve one and control valve two, operation is then keeped in repair or processed to the remaining combustion gas in opening controlling valve three and the emptying connecting tube of control valve four and combustion gas arm, to eliminate safe hidden trouble.The utility model is simple in structure, safe and reliable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
embodiment
Referring to Fig. 1, the utility model comprises combustion gas supervisor 1, combustion gas arm 2 and with the connecting tube 6 of user's indoor fuel gas equipment connection, combustion gas supervisor 1 is connected with combustion gas arm 2 by control valve 10, combustion gas arm 2 is connected with connecting tube 6 by control valve 7, on the combustion gas arm 2 between control valve 10 and control valve 7, be connected with the exhaust stack 8 towards atmosphere, exhaust stack 8 is provided with control valve 3, connecting tube 6 is connected by exhaust stack 12 with exhaust stack 8, exhaust stack 12 be positioned at control valve 3 with the connecting end of exhaust stack 8 after (after being positioned at the air outlet of control valve 3), exhaust stack 12 is provided with control valve 5.
Described exhaust stack 8 is provided with detecting tube 11, is connected with ball valve 4 on detecting tube 11, for detection of the leakage of control valve 3,5.
The outlet end of described exhaust stack 8 is provided with flame trap 9.
Control valve of the present utility model can be realized and opened or close by manual control, also can be by autocontrol mode and gas alarm system interlink.The utility model be specially adapted to ventilation condition bad with gas place (as being arranged on basement, semibasement or underground confined space), or with gas point apart from 100 meters of outdoor ground height with first-class with the higher place of gas point safety class.Exhaust stack of the present utility model preferably stretches out 2 meters, eaves or exhaust stack is caused to appropriate location and diffuses.Exhaust stack stretches out roofing suggestion grounding-for-lightning device is set.The utility model is installed for gas pipeline, needing repairing or when processing accident, first closed control valve one and control valve two, operation is then keeped in repair or processed to the remaining combustion gas in opening controlling valve three and the emptying connecting tube of control valve four and combustion gas arm, to eliminate safe hidden trouble.The utility model is simple in structure, safe and reliable.
