[0001] This utility model relates to the field of flow meter technology, specifically to an economical portable gas mass flow meter. Background Technology

[0002] Patent application CN202221051570.X discloses a thermal gas mass flow meter, belonging to the field of flow meters. It includes a mounting base with a bearing embedded in its upper surface. A rotating rod is connected to the inner wall of the bearing, and a support plate is connected to the upper end of the rotating rod. An adjusting component is mounted on the upper end of the support plate, and the flow meter body is mounted on the upper end of the adjusting component. A moving groove is formed on the upper end of the mounting base, and a moving block is slidably connected within the moving groove. The upper end of the moving block passes through the opening of the moving groove and extends upwards, connecting to a connecting block. A spring is fixedly connected to the inner wall of the moving groove on the side opposite to the rotating rod, and the other end of the spring is connected to the corresponding side wall of the moving block. This application overcomes the shortcomings of the prior art by adjusting the angle of the flow meter through the interaction of structures such as the mounting base, bearing, rotating rod, support plate, flow meter body, moving groove, moving block, connecting block, spring, limiting rod, limiting disc, and limiting groove, thereby meeting the needs of different users and improving the applicability of the device.

[0003] In the prior art, including the aforementioned patents, most gas mass flow control gauges are connected via flanges, bolts, and gaskets, which makes installation cumbersome. Furthermore, the lack of connection between the bolts and nuts results in insufficient tightness during installation and makes subsequent maintenance more difficult.

[0004] Therefore, an economical and portable gas mass flow meter is needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an economical portable gas mass flow meter to solve the technical problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an economical portable gas mass flow meter, comprising a gas mass flow meter, wherein the gas mass flow meter is connected to a pipeline via a portable connection device;

[0007] The portable connecting device includes four semicircular rings, two of which are slidably connected to the outer ring of the pipe, and the other two are slidably connected to both ends of the gas mass flow meter. The semicircular rings are symmetrically perforated, and the perforations are slidably connected to the connecting rod. One end of the connecting rod is provided with a through connecting groove, and the through connecting groove is slidably connected to the locking pin.

[0008] A groove is provided at one end of the semicircular ring, and a protrusion is provided at the other end of the semicircular ring. The groove and the protrusion are engaged.

[0009] Furthermore, the gas mass flow meter is connected to a first mating flange arranged symmetrically at both ends. The first mating flange has a first circular groove and a first rubber gasket is placed in the first circular groove. One end of the pipe is connected to a second mating flange. The second mating flange has a second circular groove and a second rubber gasket is placed in the second circular groove. The outer ring of the first circular groove and the inner ring of the second circular groove are slidably connected, and the first rubber gasket and the second rubber gasket are mated.

[0010] Furthermore, the first rubber pad has annular grooves spaced at equal intervals from small to large, and the second rubber pad has annular rubber sheets spaced at equal intervals from small to large, with the annular rubber sheets engaging with the annular grooves.

[0011] Furthermore, beveled surfaces are formed at one corner of the annular rubber sheet near the annular groove.

[0012] Furthermore, the bottom corner of the locking pin has an inclined surface.

[0013] Compared with the prior art, the beneficial effects of this utility model are: this economical portable gas mass flow meter is reasonable and has the following advantages:

[0014] The four semicircular rings are connected by connecting rods and locking pins, making installation quicker and more portable. They also provide a more even and tight connection. When force is applied to a certain part of the interface, the four semicircular rings interact with each other through the grooves and protrusions, thus bringing back the force. Compared to bolt connections, where force is continuously applied to a certain point, leading to bolt damage and leakage, subsequent damage only requires replacement of the damaged parts, without replacing the entire connection, making it more economical and practical.

[0015] By connecting the annular rubber sheet to the annular groove, the pressure increases after the gas enters, and the multiple annular grooves and multiple annular rubber sheets are compressed, making the two more tightly connected and further improving the sealing performance. By opening beveled edges at one end of the annular rubber sheet near the annular groove, it is easier to connect the annular rubber sheet to the annular groove, avoiding errors and difficulties in connection.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 The present invention provides a technical solution: an economical portable gas mass flow meter, comprising a gas mass flow meter 1, which is connected to a pipeline 2 via a portable connecting device 3; the portable connecting device 3 includes four semicircular rings 31, two of which are slidably connected to the outer ring of the pipeline 2, and the other two are slidably connected to both ends of the gas mass flow meter 1; the semicircular rings 31 have symmetrically formed through holes, which are slidably connected to connecting rods 32; one end of the connecting rod 32 has a through connecting groove 321, which is slidably connected to a locking pin 33; one end of the semicircular rings 31 has a groove 311, and the other end of the semicircular rings 31... The system features a protrusion 312, with the groove 311 engaging with it. Four semi-circular rings 31 are connected by a connecting rod 32 and a locking pin 33, allowing for quicker and more convenient installation. This also ensures a more even and tight connection. When force is applied to a point on the interface, the four semi-circular rings 31 interact with the protrusion 312 via the connecting rod 32 and the locking pin 33, generating a reaction force to pull the force back from the point of application. Compared to bolt connections, where force is applied continuously at any point, potentially causing bolt damage and leakage, subsequent damage only requires replacement of the damaged component, eliminating the need to replace the entire system, making it more economical and practical.

[0023] Gas mass flow meter 1 is connected to a first docking flange 11 symmetrically arranged at both ends. The first docking flange 11 has a first circular groove, and a first rubber gasket 12 is placed in the first circular groove. One end of pipe 2 is connected to a second docking flange 21. The second docking flange 21 has a second circular groove, and a second rubber gasket 22 is placed in the second circular groove. The outer ring of the first circular groove and the inner ring of the second circular groove are slidably connected. The first rubber gasket and the second rubber gasket 22 are mated. The sliding connection between the outer ring of the first circular groove and the inner ring of the second circular groove can further improve the sealing performance of the first rubber gasket 12 and the second rubber gasket 22. When the pressure at the connection of pipe 2 increases, the first rubber gasket 12 and the second rubber gasket 22 will not burst out under pressure, but will be squeezed tighter and remain between the outer ring of the first circular groove and the inner ring of the second circular groove.

[0024] The first rubber gasket 12 has annular grooves of varying sizes at equal intervals, and the second rubber gasket 22 has annular rubber sheets of varying sizes at equal intervals. The annular rubber sheets are connected to the annular grooves. Through the connection between the annular rubber sheets and the annular grooves, the pressure increases after gas enters, and the multiple annular grooves and multiple annular rubber sheets are compressed, thereby making the two more tightly connected and further improving the sealing performance.

[0025] The annular rubber sheet near the annular groove has beveled edges at one end. The beveled edges make it easier for the annular rubber sheet to align with the annular groove, avoiding errors and difficulty in alignment. The bottom corner of the locking pin 33 has an inclined surface 331. The inclined surface 331 of the locking pin 33 makes it easier to insert the locking pin 33 into the connecting groove 321, thereby further facilitating installation.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
