Knowledge of some relevant safety risks for leak-proof gas drainers. 1. Function of leak-proof gas drainer The main function of the gas drain is to collect and discharge the condensed water, water and dirt in the gas pipe network to ensure the smooth flow of the gas pipeline. If the water in the gas pipeline is not excluded, it will accelerate the corrosion of the pipeline and cause the pipeline to deform and crack.
Knowledge of some relevant safety risks for leak-proof gas drainers.
1. Function of leak-proof gas drainer
The main function of the gas drain is to collect and discharge the condensed water, water and dirt in the gas pipe network to ensure the smooth flow of the gas pipeline.
If the water in the gas pipeline is not excluded, it will accelerate the corrosion of the pipeline and cause the pipeline to deform and crack.
2. Risk analysis of leak-proof gas drainers.
(1) The pressure of the gas pipeline suddenly rises, causing the water seal of the drain to rupture, resulting in gas leakage and causing fire, explosion, poisoning, and suffocation accidents.
(2) The setting of the effective water seal height of the drain is unreasonable, which may cause fire, explosion, poisoning and suffocation accidents due to gas leakage.
(3) The drain is not equipped with gas detection alarm device and safety warning signs, and gas leakage may cause gas poisoning accidents.
(4) In cold areas, the drain is not equipped with heating and heat preservation measures, which causes the drain pipe and barrel of the drain to freeze and cannot work normally, resulting in gas leakage.
(5) The long-term operation of the drain will cause serious corrosion of the drain, which may cause the effective water seal height of the drain to decrease and gas leakage.
3. Classification of leak-proof gas drainers
According to the way of sealing gas, it can be divided into water seal drainage (vertical water seal drainage and horizontal water seal drainage) and dry drainage.
4. Leak-proof device of leak-proof gas drainer
The anti-leakage device is composed of float, indicating guide rod, lever, fulcrum, valve plate, pin shaft, etc.
Its principle of action: When the water level of the drain drops to a certain level or is broken down, the float will move downward under the action of its own weight, and the valve plate connected to the float will automatically close the lower mouth of the water seal pipe through leverage to prevent gas Leakage.
5. Safety measures for leak-proof gas drainers
(1) Gas drainers shall have anti-leakage devices. When the effective water level of the explosion-proof drain is abnormally lowered due to pressure fluctuation of the gas pipe network or other reasons, it can automatically close the outlet of the latter chamber to prevent instantaneous overpressure breakdown of the gas.
(2) Ensure the effective height of the water seal of the drain, and check the height of the water seal of the leak-proof gas drain at least once a year.
(3) Upper and lower valves shall be installed on the connecting pipe between the gas main pipe and the water seal drainer.
(4) Heating and heat preservation measures shall be taken for water seal drainage ditches in cold areas. If electric heating is used, explosion-proof and leak-proof measures should be taken. If steam tracing is used, the steam pipe should be wrapped outside the body, and it is strictly forbidden to insert the steam pipe directly into the high-pressure room for heat preservation.
(5) Anti-corrosion measures shall be taken inside and outside the drain.
(6) Condensate water discharged from a gas drainer shall not be discharged into a sewer, cable trench or any place, and shall be discharged into a designated water storage pit or net collection pipe system.
When there is a gas leak, the leak-proof gas drainer can handle it in time. Usually, the gas drain can also effectively prevent gas leakage. In the use of anti-leak gas drain, there are certain skills, people in the maintenance and cleaning of anti-leak gas drain, to timely add water to the anti-leak gas drain, remove the internal air.
