Detailed Description

The venturi module structure of the present invention will now be described in greater detail with reference to the schematic drawings, in which preferred embodiments of the present invention are shown, it being understood that those skilled in the art may modify the invention herein described while still achieving the advantageous effects of the present invention. Accordingly, the following description should be construed as broadly as possible to those skilled in the art and not as limiting the invention.

The invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more fully apparent from the following description and appended claims. It should be noted that the drawings are in simplified form and are not to precise scale, and are provided for convenience and clarity in order to facilitate the description of the embodiments of the present invention.

As shown in fig. 1 and 2, an embodiment of the present invention provides a venturi tube module structure, including a venturi tube module main body 1;

a proportional valve nozzle component mounting chamber 11, a receiving chamber 12, a mixing chamber 13 and a diffusion chamber 14 are sequentially arranged in the venturi tube module body 1 in a penetrating manner along the length direction;

radial air inlet and outlet ports 15 are formed in the side wall of the Venturi tube module main body 1 at the positions of the proportional valve nozzle assembly installation chamber 11, the receiving chamber 12 and the diffusion chamber 14 in a penetrating mode;

the venturi tube module body 1 is provided with a mounting hole 16.

In the embodiment, the number of the venturi tube module main bodies 1 required is selected according to actual use requirements, and the long screws are matched with the mounting holes 16, so that splicing use of multiple forms among the venturi tube module main bodies 1 can be realized, the use requirements of a fuel cell system with multiple gas flow and power can be met by one venturi tube module, and the development cost is greatly saved.

Specifically, the plurality of venturi tube module bodies 1 may be arranged in parallel along the radial direction of the air inlet 15, as shown in fig. 3.

In fig. 3(a), three venturi module main part 1 is arranged side by side along radial business turn over gas port 15 direction and is linked up, venturi module main part 1 is provided with mounting hole 16 on the lateral wall of radial business turn over gas port 15 is through-hole or screw hole, mounting hole 16 on venturi module main part 1 in the outside its lateral wall that is provided with radial business turn over gas port 15 is the screw hole, mounting hole 16 on its lateral wall that is provided with radial business turn over gas port 15 in its remaining dune pipe module main part 1 is the through-hole, the mounting hole 16 on the mounting hole 16 of long screw follow on the venturi module main part 1 in the most inboard and the mounting hole 16 on the venturi module main part 1 in the middle of wearing out in proper order, finally with the mounting hole 16 threaded connection on the venturi module main part 1 in the outside, it is fixed to accomplish linking up side by side of three venturi module main part 1. Of course, in all the venturi tube module bodies 1 that are spliced, the mounting holes 16 on the side walls of the venturi tube module bodies that are provided with the radial air inlet and outlet 15 may be through holes, and only long screws that are longer than the above need to be selected and matched with adaptive nuts, which can be specifically shown in fig. 3 (b).

After the venturi tube module bodies 1 are connected in the parallel manner, the structure is compact, and the arrangement of the radial air inlet and outlet 15 can realize the intercommunication among the proportional valve nozzle component installation chambers 11, the receiving chamber 12 and the diffusion chamber 14 in the venturi tube module bodies 1, and during the use process, the radial air inlet and outlet 15 can be selectively sealed, so that the local non-intercommunication is realized, for example, the radial air inlet and outlet 15 corresponding to the diffusion chamber 14 is sealed, so that the diffusion chambers 14 of the venturi tube module bodies 1 are not intercommunicated. The venturi tube module bodies 1 with different numbers are selected to be connected in parallel, and the channels are simultaneously selected to be intercommunicated and adjusted, so that the multi-use requirements can be met.
