Horizontal fluid transmission assembly

Abstract

The utility model provides a horizontal fluid transmission assembly which aims at solving the problems that an existing transmission scheme cannot work under the anti-explosion requirement, and the structure of a finished product is not compact enough. The venturi valve mainly comprises a linear driving piece and a venturi valve which are adjacently arranged along the same straight line, and the venturi valve is horizontally arranged. Compared with the prior art, the venturi valve serves as a fluid transmission part, external compressed air serves as a power source, and the vacuum port of the venturi valve is communicated with the interior of the closed cavity with the pressure environment needing to be changed. The outlet of the venturi valve is automatically closed or opened through the linear driving piece to control the negative pressure state or the pressurization state of the venturi valve acting on the closed cavity, and therefore the purpose of liquid and dust suction or liquid and dust discharge is achieved. Different from a traditional vertical venturi valve installation mode, a horizontal type is matched with a bent pipe switching scheme, the installation space of finished equipment can be greatly reduced, a fluid transmission assembly can be directly attached to a closed cavity, and the appearance of the equipment is more compact and smaller.

[0019] The specific implementation of the utility model is described below in conjunction with the drawings.

[0020] The utility model provides a kind of horizontal fluid transmission assembly, to provide a kind of explosion-proof fluid transmission scheme without electricity for the existing industrial dust collection (including dust liquid) field, and the structure of this scheme is compact, can greatly improve the installation space and aesthetic degree of equipment.

[0021] As Figs. 1-2 Shown,

[0022] Example 1:

[0023] The utility model provides a horizontal fluid transmission assembly, which comprises a base 4, a cylinder and a venturi valve 2 arranged adjacent to each other in a straight line above the base 4, and the venturi valve 2 is horizontally placed, the venturi valve 2 body comprises an inlet 21 on one side and an outlet 22 and a vacuum port 23 arranged in a straight line, the outlet 22 is arranged adjacent to the driving end of the linear driving element 1, and the vacuum port 23 is arranged downwardly connected through an elbow pipe 3. A matching high base 5 is further arranged between the bottom of the cylinder and the base 4. In order to ensure that the driving end of the cylinder can be opened and closed in the linear stroke, the height of the installation position of the cylinder needs to be adjusted by arranging the matching high base 5. The driving end of the cylinder is matched with the outlet 22 of the venturi valve 2 by arranging a plug 8. The vacuum port 23 of the venturi valve 2 is connected with one end of the elbow pipe 3 through a first flange ring 6, and the other end of the elbow pipe 3 is connected with the base 4 through a second flange ring 7.
