The purpose of this regulation is to facilitate the maintenance and prevent leakage in these places-after leakage, the gas can spread rapidly without causing excessive local concentration. The higher the concentration, the greater the possibility of explosion. The faster it spreads, the more likely it is to be found. However, the gas company is not stingy. The air outside is terrible, and everyone knows it. Therefore, most gas companies turn a blind eye to the user's behavior of sealing gas meters during the acceptance process, as long as the sealing is not excessive.
What do you mean the seal is not excessive? Although there is no regulation on this point, the practice of each gas company is very uniform. You can open and close the cabinet of gas meter at any time. Open it at any time, not reserve a manhole. It is allowed to make a cabinet to seal the gas meter. Once the cupboard door is opened, the meter can be completely exposed.
Pay attention to the pipes and valves connected with the gas meter, and the maximum distance is 2~3 meters. Many users will use cabinets as standpipes for packaging, which leads to the failure of gas acceptance. The correct way is to install a door on the riser and open the door to expose the valve and connector. There must be no sundries in the cabinet used to seal the gas meter, and there must be no flammable items. You can make a partition in the cabinet to separate the gas meter. In this way, the remaining space in the cabinet can be used normally and will not be wasted. Sealing gas meters (valves, pipes) is a customized cabinet work. Without permission, the gas pipeline shall not be removed or moved. If the pipeline needs to be replaced due to special circumstances, it is necessary to find the corresponding gas company for construction.
