DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Through the personnel in this field, all the electrical components in this case are connected to their corresponding power supplies through wires, and appropriate controllers and encoders should be selected according to actual conditions to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection between the electrical components is completed in the order of working in sequence. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principles and processes, and no longer explains the electrical control.

[0020] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0021] When an access-type flow meter is damaged and needs to be repaired or replaced, it is necessary to close the valve of the pipeline in advance to ensure that there is no fluid circulation inside the pipeline. This can ensure that the fluid leakage is small during the disassembly process. However, since the flow meter is connected to the pipeline by bolts and flanges, the disassembly time is long, which will cause a long delay in the fluid transportation in the pipeline.

[0022] In view of this, the utility model provides a flow meter that is easy to install. The cooperation between the inner shell, the outer shell, the closing plate, the sensor and the impeller realizes the detachable connection between the inner shell and the outer shell. In this way, when the electronic components are damaged, the inner shell can be directly replaced without removing the bolts and flanges. This can greatly shorten the time required for maintenance, eliminate the need to close the pipeline valve for a long time, and reduce the delay time for the transportation of the fluid in the pipeline. The advantages of convenient installation and disassembly are very obvious.

[0023] Depend on Figure 1-4It can be seen that a flow meter that is easy to install in this case includes an outer shell 1, both sides of the outer shell 1 are connected with flanges 2, the top of the outer shell 1 is open, and a metering component is arranged inside the outer shell 1; the metering component includes an inner shell 3, a closing plate 4, a flare 5, a display screen 6, a battery 7, a control panel 8, a sensor 9, an impeller 10 and a sealing sleeve 11; the inner shell 3 is plugged into the outer shell 1, the top of the inner shell 3 is fixedly connected with a closing plate 4, the closing plate 4 is correspondingly provided with a flare 5 opened at the open top of the outer shell 1, the outer wall of the closing plate 4 is installed with a sealing sleeve 11, the top of the closing plate 4 is respectively installed with a display screen 6, a battery 7, a control panel 8 and a sensor 9, and the sensor 9 is electrically connected to the impeller 10 installed below the inner wall of the inner shell 3.

[0024] In the specific implementation process, it is worth pointing out that the interior of the outer shell 1 can be connected to the external pipeline through the flange 2, so as to achieve access to the pipeline and facilitate flow measurement. The impeller 10 and sensor 9 inside the inner shell 3 cooperate to record the flow and display it in real time through the display screen 6. The specific models of the display screen 6, battery 7, control panel 8 and sensor 9 are not limited, and they can meet actual needs. The expansion 5 and the closing plate 4 cooperate so that the closing plate 4 remains on the surface of the outer shell 1 after the inner shell 3 is fully inserted into the outer shell 1. With such a design, when the easy-to-install flow meter is repaired, after closing the external pipeline, the inner shell 3 can be taken out as a whole for replacement, which has little effect on the overall fluidity of the pipeline. There is no need to remove the bolts used to fix the flange 2, which reduces time waste. The valve closing cycle of the pipeline is short, and the fluid transportation will not be delayed for a long time. The outer shell 1 and flange 2 parts that need to be removed by bolts to complete the disassembly are simple castings or forgings and are not prone to failure.

[0025] In one practicable manner, see Figure 1 , Figure 2 , Figure 3 and Figure 4 A buckle cover 12 is provided above the closing plate 4, a sealing gasket 13 is installed at the bottom of the buckle cover 12, a retaining ring 16 is correspondingly provided below the buckle cover 12, the retaining ring 16 is fixedly connected to the upper part of the outer wall of the shell 1, and a sealant 17 is coated on the top of the retaining ring 16.

[0026] In the specific implementation process, it is worth pointing out that a part of the buckle cover 12 can be buckled around the top outer side of the closing plate 4, and the other part can be sleeved on the outer wall of the outer shell 1. In this way, the buckle cover 12 and the outer shell 1 can be effectively sealed by the sealant 17 and the retaining ring 16. The sealing gasket 13 is tightly buckled on the top of the closing plate 4 and the edge of the sealing sleeve 11 to ensure the sealing of this position. When disassembling, the sealant 17 is heated by a hot air gun or other device to quickly separate the buckle cover 12 from the retaining ring 16, and the specific material of the sealant 17 is not limited.

[0027] Furthermore, the four corners of the bottom of the buckle cover 12 are fixedly connected with plug rods 14 , and the plug rods 14 are correspondingly provided with plug holes 15 opened on the top of the shell 1 .

[0028] In the specific implementation process, it is worth pointing out that the insertion rod 14 and the insertion hole 15 cooperate to limit the buckle cover 12, ensuring that the buckle cover 12 and the housing 1 and the closing plate 4 are accurately buckled in position.

[0029] Furthermore, an oblique groove 18 is formed on the surface of the insertion rod 14 , and a pressing rod 20 is provided corresponding to the oblique groove 18 . The pressing rod 20 is inserted into the surface of the housing 1 and extends to the inside of the insertion hole 15 .

[0030] In the specific implementation process, it is worth pointing out that the purpose of setting the inclined groove 18 is that when the driving clamping rod 20 and the inclined groove 18 are pressed together, a force will be given to the insertion rod 14 to move downward along the insertion hole 15, thereby driving the buckle cover 12 downward, thereby ensuring that the bottom of the buckle cover 12 is tightly fitted with the sealant 17, the closing plate 4 and the sealing sleeve 11, thereby improving the sealing effect.

[0031] Furthermore, one end of the clamping rod 20 away from the insertion hole 15 is fixedly connected to a screw rod 19 , which extends to the outside of the housing 1 and is threadedly connected to the housing 1 , and one end of the screw rod 19 located outside the housing 1 is fixedly connected to a hand wheel 21 .

[0032] In the specific implementation process, it is worth pointing out that the purpose of adjusting the tightening rod 20 can be achieved through the threaded connection between the screw rod 19 and the housing 1. Of course, the function of the hand wheel 21 is to facilitate the operator to rotate the screw rod 19.

[0033] Furthermore, one end of the pressing rod 20 located inside the insertion hole 15 is in an arc shape.

[0034] In the specific implementation process, it is worth pointing out that the arc-shaped design can reduce the friction between the pressing rod 20 and the inclined groove 18, so that the insertion rod 14 can move downward more smoothly when the pressing rod 20 and the inclined groove 18 are pressed against each other.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
