First housing parts is made foundry goods, because it is being convenient on the process technology the casting of import and discharge connection on shell.Second housing parts of measuring mechanism of packing into is designed to foundry goods equally.Because two housing parts all use more expensive non-ferrous metal to make, so the cost of shell is higher.
Small-sized gas meter, they for example only are used to measure with the culinary art in tropic countries is the coal gas of purpose, the cost that shell is high accounts for the very big proportion of whole gas meter price, so be necessary to simplify the structural design of shell.
Therefore the objective of the invention is to simplify the shell of the described type of preface, production cost is reduced.
By the present invention, a kind of shell that is used to install and measure the gas meter of mechanism is proposed, comprise first housing parts and second housing parts, they detachably connect mutually along interphase, wherein first housing parts is designed to non-ferrous casting and import and discharge connection in the casting is arranged, it is characterized by: first housing parts is designed to box-shaped, and wherein, interphase extends in the installment state perpendicular; And second housing parts be designed to the wall of thin plate system.
First housing parts is with corrosion resistant non-ferrous metal manufacturing.Because second housing parts can be made profiled member with the best sheet steel of comparatively cheap thin plate, so reduced production cost.Simplified assembling in addition, because measuring mechanism can assemble by the big xsect of rear side that opens wide and fix more easily.
First housing parts and import and discharge connection are designed to an integral body.The casting upper connecting tube is simple especially on production technology.Otherwise take over must be cumbersomely with shell airtight be connected withstand voltagely.
Second housing parts preferably constitutes the rear wall of shell.Do like this and especially consider outward appearance.In addition, first housing parts and counter frame being designed to one can further reduce production costs.The counter frame is usually located at outer casing frontispiece and is used to install counter.
Coal gas flows by gas meter usually from left to right.But client also can propose different with it requirements.Past will turn to if will change the some parts that flows to whole measuring mechanism or measuring mechanism.Yet do the structure that depends on measuring mechanism like this and may bring difficulty.Now, comprise by important the further developing of shell of the present invention, establish a channel connector in the inboard of first housing parts, it feeds the entrance sleeve of standard; And channel component at one end has first joint, and it can be connected with measuring mechanism, at the other end second joint is arranged, and it can be connected with channel connector.
This channel component allows to change flow direction in simple especially mode, as long as be connected with the entrance sleeve of shell standard by means of the outlet of this channel component with measuring mechanism, this entrance sleeve is as discharge connection when change flows to.
A kind of favourable design is, first housing parts and second housing parts respectively have a flange, can sandwich a seal between them, seal has a strut rail, and the latter extends between two opposite sides and is configured as that it is flexibly placed around measuring mechanism in installment state.Therefore, seal helps fixation measuring mechanism.The strut rail of seal also plays noise abatement and vibration damping.
By another favourable feature of the present invention, the characteristics of this shell are that there is a fixed part the first housing parts inside at least one sidewall, the guide member that it is designed to cast, and the fixedly edge strip of measuring mechanism assembly can insert wherein.The measuring mechanism assembly can simply and reliably be fixed in the enclosure in this way.This fixed part does not influence sealing.
