Description
Technical field
The utility model relates to a kind of diaphragm gas meters, are a kind of single port diaphragm gas meters specifically.
Background technique
Currently, diaphragm gas meter in the market has independent air inlet and gas outlet, air inlet accesses the natural gas at family
Pipe, gas outlet connect the gas equipments such as gas-cooker, gas heater, and the left and right sides is equipped with import and export at the top of gas meter upper casing body
Connector.
Consider from design angle, two mouths of inlet, outlet will then consider two airtight quality control points, import and export connector
The other technologies such as torque require to be also the designing points for having to consider.
Consider from assembly technology angle, two inlet and outlet connectors, when assembly needs to increase accordingly the activity time, increase
Qualifying point；
From a cost perspective, need accordingly to open two mouths on upper housing, processing cost is higher, imports and exports connector
Riveting die set is upper relatively high in size and requirement, causes the buying of mold and maintenance cost higher.
Utility model content
The utility model technical issues that need to address are existing diaphragm gas meters, it is necessary to independent air inlet be arranged
And gas outlet, cause the factor for designing, considering in technique relatively more, difficulty is larger, while manufacturing the higher cost of processing.
The utility model takes following technical scheme：
A kind of single port diaphragm gas meter, including shell, fixed setting inlet and outlet component 1 on the shell；The inlet and outlet
Component 1 has the double-skin duct structure of inner and outer tubes, between the lateral wall of said inner tube and the inner sidewall of outer tube, at interval of one
Determining angle has a connecting portion, and the region between abutting connection position forms air inlet 102, and inner tube is gas outlet 101.
Further, the inlet and outlet component 1 is connect with shell riveting.
Further, the quantity of the connecting portion is 3, is spaced 120 ° of distributions.
Further, the air inlet 102 includes three arcuate sockets.
Further, the shell includes upper housing 2 and lower case, and the inlet and outlet component 1 is connect with upper housing.
Further, escape pipe is connect with gas outlet 101, and air inlet pipe is connect with air inlet 102；Escape pipe is set in air inlet
Inside pipe, and it is pierced by from the hole opened up on air inlet inside pipe wall；The place position in the hole, air inlet pipe and escape pipe sealing welding are solid
It is fixed.
Further, the gas outlet 101 is circular tube structure.
The beneficial effects of the utility model are：
1) import and export is changed to same mouth by different mouth, reduces housing seal qualifying point, improve product sealed reliable
Property.
2) part is saved, the cost of gluing, riveting tool is reduced, reduces the two steps process relativity point.
3) the same mouth of import and export, good seal performance effectively improve gauging of products accuracy, can guarantee that equipment continues normally to transport
Row.
4) import and export is the structure type with mouth, can use tracheae and be set in inside air inlet pipe, and from air inlet inside pipe wall
On be pierced by the hole that opens up, such structure can simplify the comb work into and out of tracheae, simplify cloth plumber when interior decoration
Sequence, while space can be saved.
Detailed description of the invention

In figure, 1. inlet and outlet components, 2. upper housings, 3. outlet components, 4. air inlet components, 101. gas outlets, 102. air inlets
Mouthful.
Specific embodiment
The present invention will be further described in the following with reference to the drawings and specific embodiments.
- Fig. 4 referring to fig. 2, a kind of single port diaphragm gas meter, including shell, fixed setting inlet and outlet component on the shell
1；The inlet and outlet component 1 has the double-skin duct structure of inner and outer tubes, the lateral wall of said inner tube and the inner sidewall of outer tube
Between, there is a connecting portion at interval of certain angle, the region between abutting connection position forms air inlet 102, inner tube
For gas outlet 101.
In this embodiment, the inlet and outlet component 1 is connect with shell riveting.
In this embodiment, referring to Fig. 3, the quantity of the connecting portion is 3, is spaced 120 ° of distributions.
In this embodiment, referring to Fig. 3, the air inlet 102 includes three arcuate sockets.
In this embodiment, referring to fig. 2, the shell includes upper housing 2 and lower case, the inlet and outlet component 1 with it is upper
Shell connection.
In this embodiment, escape pipe is connect with gas outlet 101, and air inlet pipe is connect with air inlet 102；Escape pipe is set in
Inside air inlet pipe, and it is pierced by from the hole opened up on air inlet inside pipe wall；The place position in the hole, air inlet pipe and escape pipe sealing welding
Fixation is connect, is not shown in attached drawing.
In this embodiment, referring to Fig. 3, the gas outlet 101 is circular tube structure.
About structure, import and export reduces housing seal point in Tong Kou, with shell single-point riveting, effectively increases shell
Sealing performance, improve product；About assembly technology, a part is saved, easy for installation, time saving, the gluing of script rivets all
