Technical Field

[0001] The utility model relates to the technical field of mass flowmeters, in particular to a Coriolis mass flowmeter. Background Art

[0002] The volume of a fluid is a function of the temperature and pressure of the fluid and is a dependent variable, while the mass of a fluid is a quantity that does not change with time, space, temperature, or pressure. As mentioned above, the flow measurement value of commonly used flow meters, such as orifice flowmeters, laminar mass flowmeters, turbine flowmeters, vortex flowmeters, electromagnetic flowmeters, rotor flowmeters, ultrasonic flowmeters, and oval gear flowmeters, is the volume flow rate of the fluid.

[0003] If the connection of the existing mass flowmeter becomes loose during operation, it is easy to cause direct leakage at the connection, which will cause fluid leakage and affect the operation. Therefore, in view of the above defects, the present application proposes a Coriolis mass flowmeter. Utility Model Content

[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] See also Figure 1 and Figure 2The utility model provides a technical solution: comprising a Coriolis mass flowmeter 1 and an auxiliary sealing component 4, the two sides of the Coriolis mass flowmeter 1 are connected with connectors 2, and the side of the connector 2 away from the Coriolis mass flowmeter 1 is connected with a docking component 3, the auxiliary sealing component 4 is arranged inside the docking component 3, and the auxiliary sealing component 4 comprises a closed rubber airbag 401 and an air nozzle 402, and one side of the closed rubber airbag 401 is connected with the air nozzle 402;

[0020] By inflating the interior of the closed rubber airbag 401 through the air nozzle 402, the closed rubber airbag 401 can be expanded, thereby filling and sealing the connection of the docking component 3, so that even if the connection of the docking component 3 is slightly separated, the closed rubber airbag 401 can seal the separation to avoid fluid leakage.

[0021] like Figure 2 As shown, the docking assembly 3 includes a first pipe 301, a sealing gasket 302 and a second pipe 303, and the second pipe 303 is arranged on the side of the first pipe 301 away from the connector 2, and the sealing gasket 302 is arranged inside the second pipe 303. The docking assembly 3 also includes a first connecting ring 304 and a first mounting block 306, and the outside of the second pipe 303 is connected to the first connecting ring 304, and the outside of the first connecting ring 304 is mounted with the first mounting block 306. The docking assembly 3 also includes a second connecting ring 305 and a second mounting block 307, and the outside of the first pipe 301 is arranged with the second connecting ring 305, and the outside of the second connecting ring 305 is arranged with the second mounting block 307;

[0022] The sealing gasket 302 can seal the inside of the connection between the first pipe 301 and the second pipe 303 to prevent the fluid from leaking from the connection between the first pipe 301 and the second pipe 303. At the same time, the elasticity of the spring 502 can enable the gasket 503 to continuously squeeze the first mounting block 306, ensuring that the forces on the first connecting ring 304 and the second connecting ring 305 are in a continuously close state, thereby ensuring the stability of the equipment connection.

[0023] like Figure 3 As shown, the mounting assembly 5 is installed on the outer side of the docking assembly 3, and the mounting assembly 5 includes a bolt head 501, a bolt rod 504 and a bolt cap 505. The bolt rod 504 is connected to the middle of one end of the bolt head 501, and the bolt cap 505 is arranged outside the bolt rod 504. A spring 502 is arranged outside one end of the bolt head 501, and a gasket 503 is arranged at one end of the spring 502 away from the bolt head 501.

[0024] The spring 502 and the washer 503 are sleeved on the bolt rod 504 , and then the bolt rod 504 is passed through the first mounting block 306 and the second mounting block 307 , so that the bolt head 501 and the bolt cap 505 are located on both sides of the first mounting block 306 and the second mounting block 307 .

[0025] Working principle: first, place the sealing gasket 302 in the first pipe 301, and then connect the first pipe 301 to the second pipe 303, so that the first connecting ring 304 and the second connecting ring 305 are butt-jointed together, then put the spring 502 and the gasket 503 on the bolt rod 504, and then pass the bolt rod 504 through the first mounting block 306 and the second mounting block 307, so that the bolt head 501 and the bolt cap 505 are on both sides of the first mounting block 306 and the second mounting block 307, so as to realize the extrusion and fixation of the second connecting ring 305 and the first connecting ring 304, realize the connection of the first pipe 301 and the second pipe 303, and realize the installation of the equipment, and then inflate the closed rubber airbag 401 through the air nozzle 402, so that the closed rubber airbag 401 is inflated inside the first connecting ring 304 and the second connecting ring 305, so as to inflate the first connecting ring 304 and the second connecting ring 305. The connection of the connecting ring 305 is sealed to achieve the installation connection of the equipment, and then the fluid is passed into the equipment, thereby passing through the second pipe 303, the first pipe 301 and the connector 2, so that the fluid enters the Coriolis mass flowmeter 1 for detection. The Coriolis mass flowmeter 1 is a device that directly measures the mass flow rate by using the principle that the Coriolis force proportional to the mass flow rate is generated when the fluid flows in a vibrating pipe. It consists of a flow detection element and a converter. In order to resist this forced vibration, the fluid will give the pipe a reaction force perpendicular to its flow direction. Under the action of this force called the Coriolis effect, the vibration of the pipe is not synchronized, and there will be a difference in the timing of the vibration of the inlet section pipe and the outlet section pipe. The difference is due to the opposite flow direction of the fluid in the inlet section and the outlet section. This is called the phase time difference, and this difference is proportional to the magnitude of the mass flow rate of the fluid flowing through the pipe.
