Description

Technical Field

[0001] The utility model relates to the technical field of gas flow meters, in particular to a display connecting structure for a gas flow meter. Background Art

[0002] A gas flow meter is an instrument used to measure fluid flow and is widely used in various fluid control systems. It determines the gas flow rate by measuring parameters such as the speed, pressure and temperature of the gas passing through a pipe or pipeline.

[0003] For example, the authorization announcement number "CN210198463U" is a gas flow meter that is easy to install. It is connected to both ends of the flow tube through a T-shaped clamp block, which can enhance the sealing performance of the gas flow meter and facilitate the replacement of the sealing gasket at any time, ensuring that non-measured gases cannot enter the pipeline, thereby avoiding the phenomenon of incorrect measurement data. However, this device is not convenient for disassembling the display. When the display fails, the display needs to be replaced, but the existing equipment is not convenient for quick replacement of the display, making the device more inconvenient to use. At the same time, the device is not convenient for quick corresponding installation between the flanges, which makes the installation time of the device longer when it is used, resulting in a longer installation time of the device. Utility Model Content

[0004] The utility model aims to solve the problems of inconvenience in use and long installation time of the device, and proposes a display instrument connection structure for a gas flow meter.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A display connection structure for a gas flow meter is designed, including a shell and a base. The upper end of the shell is fixedly connected to the base. The upper end of the base is fixedly connected to a straight pipe. The inner wall of the straight pipe is provided with a connection structure. Both ends of the shell are fixedly connected to a first flange. The straight pipe is threadedly connected to a bolt through a threaded hole opened on the surface, and one end of the bolt passes through the straight pipe.

[0007] Preferably, the connecting structure includes a first pipe and a second flange, the outer wall of the first pipe is fitted with the inner wall of the straight pipe, the upper end of the first pipe is fixedly connected to the second flange, the outer wall of the second flange is fixedly connected to a ring, the upper end of the ring is fixedly connected to multiple groups of round rods, the outer walls of the round rods are respectively fitted with multiple groups of through-hole blocks, one end of the multiple groups of through-hole blocks are fixedly connected to the third flange, and the upper end of the third flange is fixedly connected to the second pipe.

[0008] Preferably, the upper end of the second pipeline is fixedly connected to the intelligent flow meter integrator, and the upper end of the second flange is fastened to the third flange by bolts and nuts.

[0009] Preferably, the lower end of the first pipe is pressed against the base via a rubber pad, and the first pipe is plugged into a bolt via a groove provided on the outer wall.

[0010] The utility model proposes a connection structure for a display instrument for a gas flow meter, which has the beneficial effect that: through the cooperation of the connection structure and the straight pipe, the operator respectively sleeves the six through-hole blocks provided on the surface of the third flange onto the surfaces of the six round rods, so that the third flange can be fitted with the second flange, and the second flange and the third flange can be made more stable under the action of the through-hole blocks and the round rods, making it more convenient for the operator to fix them with bolts and nuts. When the intelligent flow meter integrator fails, the operator rotates the bolt so that the bolt no longer engages with the groove on the surface of the first pipe. The operator pulls the first pipe out of the straight pipe, replaces it with a new one, and then installs it again. By positioning it during installation, the intelligent flow meter integrator is prevented from tipping over, which shortens the time required for installation of the device. At the same time, the first pipe and the straight pipe can be quickly disassembled, making the device more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention will be further described below with reference to the accompanying drawings:

[0018] Refer to the attached Figure 1-5In this embodiment, a display connection structure for a gas flow meter includes a housing 1 and a base 3. The upper end of the housing 1 is fixedly connected to the base 3. A straight tube 4 is fixedly connected to the upper end of the base 3. The inner wall of the straight tube 4 is provided with a connection structure 5. A temperature sensor, a pressure sensor, a piezoelectric crystal sensor, a vortex generator, and a deswirlizer are provided inside the housing 1. Both ends of the housing 1 are fixedly connected to a first flange 2. The straight tube 4 is threadedly connected to a bolt 7 through a threaded hole opened on the surface. One end of the bolt 7 passes through the straight tube 4.

[0019] The upper end of the second pipe 502 is fixedly connected to the intelligent flow meter integrator 6. A display is provided on the front side of the outer wall of the intelligent flow meter integrator 6, so that the intelligent flow meter integrator 6 can display the detection results. The upper end of the second flange 506 is tightly pressed against the third flange 501 by bolts and nuts. The lower end of the first pipe 507 is tightly pressed against the base 3 by a rubber pad, and the rubber pad plays a sealing role. The first pipe 507 is connected to the bolt 7 through the groove opened on the outer wall, and the position of the first pipe 507 can be fixed by the bolt 7.

[0020] The connecting structure 5 includes a first pipe 507 and a second flange 506. The outer wall of the first pipe 507 fits against the inner wall of the straight pipe 4. The upper end of the first pipe 507 is fixedly connected to the second flange 506. The outer wall of the second flange 506 is fixedly connected to the ring 505. The first pipe 507 and the second pipe 502 can be connected through the second flange 506 and the third flange 501. The upper end of the ring 505 is fixedly connected to multiple groups of round rods 503. The round rods 503 can be provided with six, so that the through holes for mounting bolts between the second flange 506 and the third flange 501 can be quickly aligned. The outer walls of the round rods 503 are respectively fitted with multiple groups of through-hole blocks 504. One end of the multiple groups of through-hole blocks 504 is fixedly connected to the third flange 501. The upper end of the third flange 501 is fixedly connected to the second pipe 502.

[0021] Working principle:

[0022] When installing the display of the gas flow meter:

[0023] The operator respectively puts the six through-hole blocks 504 provided on the surface of the third flange 501 onto the surfaces of the six round rods 503, so that the third flange 501 can be fitted with the second flange 506. The action of the through-hole blocks 504 and the round rods 503 can make the second flange 506 and the third flange 501 more stable, completing the installation of the intelligent flow meter integrator 6 and the front-end display. When in use, the detected data can be displayed through the display on the surface of the intelligent flow meter integrator 6.

[0024] Maintenance process:

[0025] When the intelligent flow meter integrator 6 fails, the operator turns the bolt 7 so that the bolt 7 no longer engages with the groove on the surface of the first pipe 507. The operator pulls out the first pipe 5 from the straight pipe 4 (when pulling out the first pipe 5, the ventilation of the pipe connected to the shell 1 needs to be stopped), replaces it with a new one, and then installs it again. The operator disassembles the second flange 506 and the third Farad plate 501 and repairs the intelligent flow meter integrator 6.

[0026] While the present invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
