Abstract
The utility model relates to a core component of a gas meter, in particular to a novel double-precision adjustment machine core of the gas meter. The novel double-precision adjustment machine core of the gas meter comprises an air bag, wherein an air outlet pipe and an air inlet are formed above the air bag, a valve cover which moves in a reciprocating mode is arranged on the air inlet, the valve cover is hinged to a valve cover connecting rod, and the other end of the valve cover connecting rod is hinged to a crank shaft in an eccentric mode. A lower adjusting disc is fixedly arranged on the top of the crank shaft, an upper adjusting disc is arranged on the upper portion of the lower adjusting disc in a mutually-rotating mode, the upper adjusting disc is hinged to a connecting rod, the connecting rod is hinged to a toggle joint, the toggle joint is hinged to the air bag, a coarse tuning pointer is arranged in the center of the upper adjusting disc in a rotating mode, a fine tuning pointer is arranged on the edge of the upper adjusting disc in a rotating mode, and the bottom of the coarse tuning pointer and the bottom of the fine tuning pointer are respectively provided with a shifting pin in an eccentric mode. Adjusting groove openings are formed in the positions, corresponding to the shifting pins, of the lower adjusting disc. The shifting pins and the adjusting groove openings are matched so as to limit relative movement of the upper adjusting disc and the lower adjusting disc. Due to the facts that two sets of precisions are used for adjustment and coarse tuning and fine tuning are combined, the novel double-precision adjustment machine core of the gas meter improves the adjustment precision of an error curve.
Description
Technical field
The utility model relates to a kind of core component of gas meter, flow meter, especially a kind of novel double precision regulating gas table movement.
Background technology
Along with the development of society, gas meter, flow meter uses and becomes very extensive, after installing for gas meter, flow meter, needs to adjust the graph of errors of gas meter, flow meter.Conventional regulating device adopts an adjusting mechanism, by adjusting the relative angle of adjustment disk and crank axle, thereby reaches the purpose of alignment error curve.But such regulating device, degree of regulation are not high.
Summary of the invention
The utility model provides a kind of graph of errors degree of regulation higher novel double precision regulating gas table movement.In order to reach above goal of the invention, the technical solution of the utility model is as follows:
A kind of novel double precision regulating gas table movement comprises air bag; Described air bag top is provided with escape pipe and air intake opening, and air intake opening is provided with the valve gap of back and forth movement; Described valve gap and valve gap rod hinge connection; Being hinged on the crank axle of the other end off-centre of described valve gap connecting rod; Described crank axle top is fixedly installed lower adjustment disk; Rotate mutually described lower adjustment disk top arranges the adjusted dish; Described adjusted dish and rod hinge connection; Described connecting rod and toggle are hinged; Described toggle is hinged on the air bag; Described adjusted disk center rotates the coarse adjustment pointer is set, and the edge rotates the fine tuning pointer is set; Pin is stirred in the bottom of described coarse adjustment pointer and the fine tuning pointer all setting of off-centre; The adjusting notch is offered in position corresponding with stirring pin on the described lower adjustment disk; The described pin of stirring cooperates relatively moving of restriction adjusted dish and lower adjustment disk with the adjusting notch.
Described valve gap comprises front valve gap and rear valve gap, the two symmetry be distributed in the crank axle both sides;
Described front valve gap and rear valve gap are limited to come and go on the valve gap guide rod and move.
Use the technical solution of the utility model, use two cover precision to regulate, combine by coarse adjustment and fine tuning, improved the graph of errors degree of regulation.
Description of drawings
Fig. 1, the 2nd, structural representation of the present utility model;
Fig. 3 is the local enlarged diagram of B part among Fig. 2.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Such as Fig. 1,2 and shown in Figure 3, this double precision regulating gas table movement main body is the same with conventional gas meter movement, main body is air bag 10, the top is provided with escape pipe 5 and air intake opening, air intake opening has former and later two, and be symmetrical arranged, be respectively equipped with front valve gap 7 and the rear valve gap 6 of back and forth movement on two air intake openings, front valve gap 7 and rear valve gap 6 are hinged with valve gap connecting rod 13 respectively, being hinged on the crank axle 12 of the other end off-centre of described valve gap connecting rod 13, crank axle 12 rotates and is arranged on the axis of symmetry of two air intake openings.Front valve gap 7 and rear valve gap 6 all are limited on the linear valve gap guide rod 4, thereby make the round movement of its straight line.
Described crank axle 12 tops are fixedly installed lower adjustment disk 11, an adjusted dish 3 is installed in described lower adjustment disk 11 tops, adjusted dish 3 center rotatings arrange coarse adjustment pointer 8, the edge rotates fine tuning pointer 9 is set, pin 14 is stirred in the bottom of described coarse adjustment pointer 8 and the fine tuning pointer 9 all setting of off-centre, the position corresponding with stirring pin 14 offered and regulated notch 15 on the lower adjustment disk 11, and the described pin 14 of stirring is stuck in and regulates in the notch 15, thereby limits relatively moving of adjusted dish 3 and lower adjustment disk 11.
Hinged two connecting rods 2 of the edge same position of adjusted dish 3, connecting rod 2 is hinged with toggle 1, and two toggles 1 are hinged on respectively again on the air bag 10, and articulated position is symmetrical about crank axle 12 front and back.
When using, after gas meter, flow meter installs, first by coarse adjustment pointer 8 regulating error curves, again by the graph of errors after the 9 correction coarse adjustment of fine tuning pointer, through two steps joint, thereby make the more accurate of graph of errors adjusting.
