    • A gas meter installation comprises a gas meter and a regulator which are attached to a manifold. The manifold connects to a utility pipe for supplying gas and includes an orifice and various passageways for routing the gas from the utility pipe to the regulator, from the regulator to the meter, and from the meter to a house or other type of consumer. The manifold preferably has a shut-off valve integrated into the body of the manifold so that the manifold may be connected directly to the ground pipe without requiring a separate connection to a shut-off valve. The manifold greatly simplifies the installation by eliminating a number of pipes and fittings that were previously used to mount the shut-off valve, regulator, and meter together. The manifold also permits attachment and detachment of the meter or regulator independently of each other so that these components may be individually serviced or replaced.
    • 燃气表安装包括附接到歧管的气量计和调节器。 歧管连接到用于供应气体的公用管道,并且包括孔口和各种通道,用于将气体从公用设施管道传递到调节器,从调节器到仪表,以及从仪表到家庭或其他类型的消耗器。 歧管优选地具有集成到歧管主体中的截止阀,使得歧管可以直接连接到接地管,而不需要与截止阀的单独连接。 歧管通过消除以前用于将截止阀,调节器和仪表安装在一起的许多管道和配件,大大简化了安装。 歧管还允许仪表或调节器彼此独立地附接和拆卸,使得这些部件可以单独维修或更换。
