Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

As shown in fig. 1 to 3, the utility model relates to a casing for gas ultrasonic flowmeter, include: the gas pipe type gas-insulated shell comprises a shell body 1 and flange plates 2 fixedly connected to two sides of the shell body 1, wherein a gas pipe 3 is fixedly connected to the inner side of the shell body 1;

the top of the shell body 1 is provided with a base 4 for bearing a control component 24, and the base 4 is provided with a first through hole 5 and a first groove group 7 which penetrates through the shell body 1 and the air pipe 3 and is used for bearing a sensor component 6;

a second groove group 9 which penetrates through the shell body 1 and the air pipe 3 and is used for installing the transducer assembly 8 is arranged on the side portion of the shell body 1, a second through hole 10 which is used for transmitting a pipeline 11 to which the transducer assembly 8 belongs is arranged on the second groove group 9, and the pipeline 11 extends to the first through hole 5 along a passage 25 between the shell body 1 and the air pipe 3 through the second through hole 10.

Here, a cover is disposed outside the base 4, and the control assembly 24 is preferably fixedly connected to the cover through a screw. The sensor assembly 6 measures the state parameters of the gas flow by extending the sensor inside the gas tube 3.

And a cover plate is disposed on the surface of the second groove group 9 to protect the second groove group 9 and the second via hole 10.

The application provides a casing for gaseous ultrasonic flowmeter, through setting up the transducer group in casing body lateral part to stretch into the wire pipeline of transducer group through the second via hole that sets up in the casing body lateral part and stretch out with connection control assembly along the first via hole of passageway follow base, thereby avoided the pipeline of transducer group to arrange in gaseous ultrasonic flowmeter's outside and cause the damage.
