Abstract
The utility model relates to an electronic control module assembly for a gas meter with an electronic additional device. A power supply, a control circuit board, a data interchange interface, input control keys and an output prompt device are assembled in an independent assembly box and sealed, and the utility model is provided with an interface which is connected with an external signal wire and a control valve. In the assembly box, all parts are electrically connected through the methods of welding, splicing, etc.; in this way, the electronic control part of the gas meter is integrated and sealed in the assembly box to form an independent module. Thereby, the utility model has the advantages that the structure of the electronic control part is compact, and the connection between all parts is reliable; the utility model obtains good sealing effect and enhances the corrosion resistance of the electronic control part; besides, when only the electronic control part generates a fault, only the assembly box is disassembled for maintenance without damaging the other parts of the gas meter, and thus the maintenance is convenient.
Description
Technical field
The utility model relates to gas meter, flow meter (hereinafter to be referred as " the gas meter, flow meter ") technology of charged sub-attachment device, and it comprises the gas meter, flow meter of electronic telemetering type gas meter, flow meter and band IC-card prepaid devices.Be specifically related to a kind of electronic control module assembly of gas meter, flow meter.
Background technology
The electronic control part of present gas meter, flow meter just is installed in each parts in the housing that is connected with base table scatteredly, this housing generally has the anti-dismounting that legal measurement verification department is provided with and the seal of tamper-proof mechanical measuring apparatus, and the shortcoming of this structure is:
1, loosely organized, connecting line lost efficacy easily or is destroyed each other;
2, not sealing well is easy to immerse water and corrosive gas or liquid;
When 3, only electronic control part breaks down when mechanical metering section is intact, must put in order to show to pull down and open the housing maintenance, certainly will destroy seal.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming that existing structure exists, and a kind of electronic control module assembly of gas meter, flow meter of charged sub-attachment device is provided, and makes the electronic controller more reliable performance of gas meter, flow meter, maintenance more convenient.
The utility model is realized above-mentioned purpose in the following manner:
The electronic control module assembly of this gas meter, flow meter is power supply, control circuit board, data exchange interface, input operating key and output suggestion device mutual group to be contained in one independently also seal in the assembly box, reserves the interface that is connected with operation valve with external signal line.And in the assembly box, each several part is electrically connected by modes such as welding, grafting, like this, the electronic control part of gas meter, flow meter just is integrated and is sealed in the assembly box, formed an independently module, bring following tangible advantage thus: the one, make the compact conformation of electronic control part, connection each other is more reliable; The 2nd, can obtain better sealing effectiveness, improve the corrosion resistance of electronic control part; The 3rd, when just electronic control part breaks down, only need take off this assembly box and keep in repair, and needn't destroy the other parts of gas meter, flow meter, make maintenance more convenient.
Description of drawings
Fig. 1 is the structural representation of a kind of specific implementation of the present utility model.
Embodiment
What show among Fig. 1 is that electronic control circuit with intelligent gas meter is the structural drawing of the electronic control module assembly of example, its mainly by lithium battery 10, control circuit board 7, as the IC-card seat 5 of data exchange interface, form as the LCDs 11 and the EC assembly box 8 of output suggestion device.Control circuit board 7 and IC-card seat 5 all use prior art.At first, lithium battery 10 is contained in the arc groove of EC assembly box 8, IC-card seat 5 is stuck in four holes of EC assembly box 8 fixing by four pin, then the plug of lithium battery 10 and IC-card seat 5 is inserted in the socket of control circuit board 7, after the input operating key 12 that exposes on the circuit board 7 to be controlled puts button seal gasket 6 and external socket cover EC assembly lead-in wire sealing shroud 9, with screw 4 control circuit board 7 is fixed in the EC assembly box 8 again, by self-tapping screw 1 EC assembly lid 3 and EC assembly box 8 are connect again, faying face is coated with fluid sealant, and the demonstration sealing paster 2 that exposes LCDs 11 subsides PC materials is sealed.
Thus, the control circuit of intelligent gas meter partly becomes the integral body that sealing is integrated, and only socket inserts outside metering signal to need and the operation valve connecting line gets final product work from exposing.As for this EC assembly and the connecting mode that housing is installed, the mode that can adopt clamping, screw attachment, articulates, this example employing be that U type groove and housing by EC assembly box 8 sides articulates.
Claims (1)
1, a kind of electronic control module assembly of gas meter, flow meter of charged sub-attachment device, include power supply, control circuit board, data exchange interface, input operating key and output suggestion device, it is characterized in that: power supply, control circuit board, data exchange interface and output suggestion device mutual group are contained in one and independently also seal in the assembly box, reserve the interface that is connected with operation valve with external signal line, in the assembly box, each several part is electrically connected by welding or inserting mode.
