Abstract
An industry gas meter fine adjustment connecting rod comprises a left-handed rotation push rod, a left-handed rotation nut, a push rod nut, a right-handed rotation nut and a right-handed rotation push rod. The left-handed rotation push rod, the left-handed rotation nut, the push rod nut, the right-handed rotation nut and the right-handed rotation push rod are sequentially connected. The left-handed rotation push rod is integrally formed by a push rod and a screw rod. The connecting position of the push rod and the screw rod is provided with a circular bead. The diameter of the screw rod is smaller than that of the push rod. The screw rod is composed of inner side threads and outer side threads. The inner side threads correspond to the left-handed rotation nut. The outer side threads correspond to the push rod nut. The direction of the inner side threads is opposite to that of the outer side threads. The diameter of the outer side thread portion of the screw rod is slightly larger than that of the inner side thread portion of the screw rod. The outer diameter of the left-handed rotation nut is the same as the diameter of the push rod portion of the left-handed rotation push rod. The outer diameter of the push rod nut is slightly smaller than that of the left-handed rotation nut. The size of the right-handed rotation push rod is the same as that of the left-handed rotation push rod. The direction of inner side threads of the right-handed rotation push rod is opposite to that of inner side threads of the left-handed rotation push rod. The direction of outer side threads of the right-handed rotation push rod is opposite to that of outer side threads of the left-handed rotation push rod. The industry gas meter fine adjustment connecting rod is simple in structure, reasonable in design and effective in reducing measurement precision error of a gas meter.
Description
Technical field
The utility model belongs to the gas meavuremeut field, relates to a kind of industrial combustion gas table fine setting coupling rod.
Background technique
Gas meter in using at present occurs larger deviation owing to the component deviation accumulation so that gas meter measures in process of production, and present solution is to regulate with several coupling rods that are uneven in length, to reach designing requirement.But in large-scale industry and commerce gas meter, this kind method can not 100% satisfies the measuring accuracy requirement, needs coupling rod to have fine adjustment function.
Summary of the invention
The purpose of this utility model provides a kind of industrial combustion gas table fine setting coupling rod, makes coupling rod have fine adjustment function, satisfies the needs that the large scale industry gas meter is produced.
To achieve these goals, technical solution adopted in the utility model is, a kind of industrial combustion gas table fine setting coupling rod, comprise the left-handed catch bar, left-handed nut, catch bar nut, right-handed nut, the dextrorotation catch bar that connect successively, described left-handed catch bar is comprised of push rod and screw mandrel one, described push rod and screw mandrel joint are a shoulder, and the diameter of described screw mandrel is less than the diameter of described push rod; Described screw mandrel is comprised of inside and outside two-part screw thread, and wherein inside thread is corresponding with left-handed nut, and outside screw is corresponding with the catch bar nut, described inside thread and described outside screw opposite direction; Described outside screw part screw mandrel slightly larger in diameter is in the diameter of inside thread part screw mandrel; Described left-handed nut external diameter is identical with the pusher section diameter of left-handed catch bar; The external diameter of described catch bar nut is slightly less than the left-handed nut external diameter; Described dextrorotation catch bar is identical with described left-handed catch bar size, inside thread opposite direction, outside screw opposite direction; Described left-handed nut is identical with described right-handed nut's size, and hand of spiral is opposite.
Further, the screw mandrel length of the inside thread of described left-handed catch bar, dextrorotation catch bar part is greater than the screw mandrel length of outside screw part.
The beneficial effects of the utility model are:
The utility model is simple in structure, reasonable in design, has effectively reduced the trueness error of gas meter metering.
