Description
Technical field
The utility model relates to mechanical field, is specifically related to a kind of coriolis mass flowmeters import and export combined type and divides flow cone.
Background technology
Along with wide weary use and develop rapidly of CNG technology in China, the technology of CNG filling machine and application are also at high speed development, and market demand is also increasing; As the coriolis mass flowmeters of one of main core component of CNG filling machine most of dependence on import of determining, it costs an arm and a leg, and has seriously restricted the development and wide weary application of Chinese CNG filling machine technology.According to the principle of Coriolis force, the relative uniformity coefficient of the fluid in two measuring tubes is good more, and the linearity of the Coriolis force of this moment is good more.We find in the development process of coriolis mass flowmeters, and the shape of the branch flow cone of the import and export of coriolis mass flowmeters and structure can produce very large influence to the overall precision of coriolis mass flowmeters.Therefore the utility model provides a kind of coriolis mass flowmeters import and export combined type to divide flow cone at this, improves the overall performance of coriolis mass flowmeters.
The utility model content
Technical problem to be solved in the utility model is how to provide a kind of import and export combined type that cooperates with coriolis mass flowmeters to divide flow cone, improves the overall performance of coriolis mass flowmeters.
The technical matters that the utility model proposed is to solve like this: construct a kind of coriolis mass flowmeters import and export combined type and divide flow cone, comprise entrance point and endpiece, it is characterized in that: entrance point and endpiece are structural symmetry, connect by body between the two, described entrance point and endpiece are by port connections, divide flow cone, two measuring tubes and measuring tube joint are formed, wherein port connections forms with the measuring tube joint and docks, between the two with a minute flow cone location, measuring tube welds after inserting the measuring tube joint, wherein dividing flow cone is to be inserted into measuring tube and measuring tube joint, and described measuring tube keeps close positioning to cooperate with dividing flow cone.
Import and export combined type according to a kind of coriolis mass flowmeters described in the utility model and divide flow cone, it is characterized in that measuring tube and measuring tube joint weld with argon arc welding; Described minute flow cone is axially and radially to be inserted into the endoporus location of measuring tube joint, and flow cone cooperated the location with circumferencial direction with measuring tube in described minute.
Import and export combined type according to a kind of coriolis mass flowmeters described in the utility model and divide flow cone, it is characterized in that, described port connections is to be enclosed within on the branch flow cone, satisfy axially with the male cone (strobilus masculinus) of minute flow cone and the inner conical surface location of port connections, radially with the endoporus location of port connections, wherein port connections also adopts integral body to compress and weld with argon arc welding with dividing flow cone.
The beneficial effects of the utility model are: the utility model is when the application of coriolis mass flowmeters, can effectively improve the yield rate of coriolis mass flowmeters, reduce the overall manufacturing cost well, very the assurance of science the overall performance of coriolis mass flowmeters.And this mode and structure also to have the part processing difficulty little, cost is low, easily characteristics such as assembling welding.The application of this mode and structure has very large help to the development of low price, high performance homemade coriolis mass flowmeters, will establish solid foundation for the market leading position of homemade coriolis mass flowmeters.

Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, this coriolis mass flowmeters is imported and exported combined type and is divided flow cone, comprise entrance point and endpiece, wherein entrance point and endpiece are structural symmetry, connect by body 5 between the two, described entrance point and endpiece by by port connections 1, divide flow cone 2, two measuring tubes 3 and measuring tube joint 4 to form, can adopt the argon arc welding fabrication between them, so can reduce the part processing difficulty effectively, reduce cost, general effect is good.
Port connections 1 docks 4 with the measuring tube joint, and between the two with minute flow cone 2 location, measuring tube 3 inserts conjunction measuring pipe adapter 4 back welding fabrications, and measuring tube 3 cooperates with minute flow cone 2 close positioning again.
During Combination Welding, earlier measuring tube 3 insertions are coupled on the measuring tube joint 4, use the argon arc welding firm welding after the tool locating.To divide flow cone 2 to insert measuring tube 3 and measuring tube joint 4 again, satisfy axially and radially and locate with the endoporus of measuring tube joint 4, circumferencial direction cooperates the location with measuring tube 3, again port connections 1 is enclosed within on the branch flow cone 2, axially with the male cone (strobilus masculinus) of minute flow cone 2 and the inner conical surface location of port connections 1, radially, on frock, compress then with argon arc welding and weld with the endoporus location of port connections 1.
Like this, fluid is when entering coriolis mass flowmeters, be introduced into the port connections 1 of import, shunt by the branch flow cone 2 of import then, enter two measuring tubes 3 more uniformly, the branch flow cone 2 that enters outlet after the flow process of measuring tube 3 is covered is again understood stream uniformly, after the port connections 1 of outlet flows out coriolis mass flowmeters, finishes the measurement of coriolis mass flowmeters convection cell.
