Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
As shown in fig. 1, an inlet adapter flange of a flow measurement converter comprises a first flange 1 and a second flange 2, wherein the first flange 1 is integrally formed on the second flange 2, a plurality of first connecting holes 11 connected with an electromagnetic valve are formed in the first flange 1, the first connecting holes 11 are aligned with corresponding through holes in the electromagnetic valve, the first flange 1 is fixed through bolts and nuts, a plurality of second connecting holes 21 connected with the flow measurement converter are formed in the second flange 2, the second connecting holes 21 are aligned with corresponding through holes in the flow measurement converter, the second flange 2 is fixed through bolts and nuts, axial leads of central holes of the first flange 1 and the second flange 2 coincide, and a channel is formed to connect the electromagnetic valve with the flow measurement converter.
In this embodiment, as shown in fig. 1, the first flange 1 is square, the first connection holes 11 are four and are respectively located on four corners of the first flange 1, and the square flange is designed to match with the connection end on the solenoid valve.
In this embodiment, as shown in fig. 1, the second flange 2 is a diamond, the two second connection holes 21 are located at two opposite corners of the second flange 2, and the diamond flange is designed to match with a connection end on a flow measurement transducer.
