Embodiment 1

[0041] like Figure 1-Figure 6 As shown, a gas meter movement includes a movement body 1, a bridge 3, a vertical shaft 5, and a counter. The movement body 1 is provided with an air outlet pipe 2, and the movement body 1 includes a movement main body 11, a movement side The cover 12 has open ends 113 at both ends of the movement main body 11 , the movement side cover 12 is fixed at the open ends 113 at both ends of the movement main body 11 , and is provided between the movement main body 11 and the movement side cover 12 There is a membrane 114, and membrane gaskets 115 are arranged on both sides of the membrane 114. The membrane divides the cavity formed between the movement main body 11 and the movement side cover 12 into two parts, the movement main body 11 and the movement side cover 12. The upper end of the cavity formed between is provided with a valve grid 34, the valve grid 34 is provided with a valve cover 35, the valve cover 35 is provided with a gap, the bridge fram...

Embodiment 2

[0045] On the basis of the gas meter core described in Embodiment 1, it is further optimized. The air outlet pipe 2 is provided with an anti-reverse ventilation sheet 21, and the anti-reverse ventilation sheet 21 is arranged obliquely. The setting of this embodiment is to prevent The gas flows in the reverse direction, and at the same time, relative to the anti-reverse ventilation sheet 21 set horizontally, the inclined setting of the anti-reverse ventilation sheet 21 can ensure that when the flow is forward, a small airflow can push the anti-reverse ventilation sheet 21 away, which ensures the sensitivity of the device. sex.

Embodiment 3

[0047] like Figure 7-Figure 8 As shown, further optimized on the basis of the gas meter core described in Embodiment 1, the fixing column 112 is sequentially set as a limit end 1121 and a mounting end 1122 from top to bottom. The diameter is smaller than the diameter of the installation end 1122 , the undercut 13 is a circular metal sheet, and an irregularly shaped through hole 131 is formed in the middle of the undercut 13 , and the minimum diameter of the through hole 131 is larger than the diameter of the limit end 1121 and smaller than the diameter of the limit end 1121 The diameter of the installation end 1122, the maximum diameter of the through hole 131 is larger than the diameter of the installation end 1122, the undercuts 13 are evenly distributed with several barbs 132 in the circumferential direction toward the center of the circle, which is convenient for the installation of the undercuts 13 and prevents the movement side cover 12 from being damaged. After pressin...

Abstract

The invention discloses a gas meter movement, which relates to the field of gas meter assembly. The movement body, bridge frame and vertical shaft of the gas meter movement are greatly improved. The method is mechanical connection, adding upside-down buckle, eliminating the use of metal diaphragm beading, and changing the material from polyoxymethylene to PBT fiber-added material, which solves the problems of low efficiency, low yield and high toxicity in the production process of the prior art. Problem; the bridge frame is changed from two-legged support to four-legged support, and a protective cover is also set to protect the valve grid and valve cover, which increases the firmness of the device while preventing the valve grid and valve cover from sliding down; the connection method of the vertical shaft is carried out. In order to improve, avoid the problems of easy dead watch and low service life caused by inconsistent relative angles of the two sets of vertical shafts.

Description

technical field [0001] The invention relates to the field of gas meter assembly, in particular to a gas meter movement. Background technique [0002] With the improvement of living standards and the strengthening of environmental protection awareness, people's daily cooking fuels have changed from firewood, coal and other wasteful and polluting conventional energy sources to the use of natural gas and gas, and even electricity and other clean energy sources. Here the gas meter will play its role. With its automatic accumulation function, those who use natural gas or pipeline gas can easily know how much gas is used, so that they can pay according to the cubic meters of gas consumed each month. . [0003] The diaphragm gas meter is a mechanical instrument, and the driving force of the diaphragm movement is the gas pressure difference at the inlet and outlet of the gas meter. Its source power is the driving force generated by the measured gas above normal pressure entering t...
