Description
Technical Field
The utility model relates to a measure technical field, concretely relates to joint design and mass flow meter for mass flow meter.
Background
Mass flowmeters are also known as coriolis flowmeters, an important design of which is dual or multi-tube meters that employ flow splitters to split the fluid from an external conduit to two or more measurement tubes for measurement. Thus, how to connect the flow splitter and the measurement tube is an important consideration.
Vacuum brazing techniques are currently commonly used to braze the flow splitters, flow tubes, and other accessory parts together. As shown in fig. 1, a flow tube 1 and a flow splitter 4 are joined together by a braze joint 2 using a vacuum brazing process. When the medium 5 passes through the flowmeter, it will directly contact the braze weld 2 through the gap 3 between the flow tube and the flow divider. Due to the composition difference between the common nickel-based brazing filler metal and the base material and the process defects generated in the brazing process, local corrosion near a stainless steel brazing joint is often caused when the brazing joint is used in a corrosive environment.
With the widespread use of mass flowmeters, corrosion of brazed joints is of increasing concern. Particularly, under the working conditions of high-corrosive media such as strong acid, strong alkali and the like, medium leakage caused by corrosion of a brazing welding seam happens occasionally, and great potential safety hazards are caused. In addition, there is a demand for improving the compressive strength of the connection portion even for a medium which is high in pressure but is not corrosive.

In view of the above, the present invention has been made to provide a joint structure for a mass flow meter and a mass flow meter which overcome the above problems.
According to an aspect of the utility model, a joint design for mass flowmeter is provided, including shunt and flow tube, still include the beaded finish, the beaded finish is set up the shunt with between the flow tube.
Preferably, the inside of the stiffening ring is connected to the outside of the flow tube.
Preferably, the outer side of the reinforcement ring is connected to the inner side of the shunt.
Preferably, the reinforcing ring is made of the same material as the flow tube.
Preferably, the bottom of the flow tube and the bottom of the reinforcing ring are connected by argon arc welding seams.
Preferably, the top of the reinforcing ring is connected with the flow divider through argon arc welding seams.
Preferably, the gap between the inside of the stiffening ring and the outside of the flow tube is filled with a braze weld.
