According to the national standard, this is not acceptable-according to the national standard, all valves, joints, meters, etc. must be exposed directly.

this regulation is for the convenience of maintenance and prevention of 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 mean. The gas outside is so ugly that everyone knows it. Therefore, most gas companies turn a blind eye to the user's behavior of sealing the gas meter 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 practices of various gas companies are very uniform, and you can open the cabinet that closes the gas meter at any time. It is to open at any time, not to reserve a manhole. It is permissible to make a cabinet to seal the gas meter, and once the cupboard door is opened, the meter can be completely exposed.

attention should be paid to the pipes and valves connected to the gas meter, and the maximum distance is 2~3 meters. Many users will use cabinets as risers to package them, which will lead to gas acceptance failure. 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, let alone 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 without wasting. 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.
