The flowmeter usually adopts the horizontal arrangement form, and the measuring pipe is usually installed at 90 degrees with the measuring pipeline, and the shunt needs to be designed with a curved flow channel. In the actual production process, the shunt is usually cast by a mold, and there is a mold opening cost. When the production batch is large, the cost can be reduced, but the shunt of some special models is in short supply, and the production batch is small, the mold opening cost is high, especially the shunt made of special materials, which also has the problems of difficult procurement and processing, further increasing the production cost. SUMMARY

[0003] In view of the problems of increasing production cost caused by small production batch and special material in the mold opening casting shunt in the prior art, the utility model provides a three -way structure shunt's mass flowmeter.

[0004] The utility model provides the following technical scheme: a three -way structure shunt's mass flowmeter, first three -way pipes and second three -way pipes are symmetrically arranged about the central axis, the first end of the first three -way pipe and the second three -way pipe is provided with closed core, the second end of the first three -way pipe is connected with the inlet joint, the second end of the second three -way pipe is connected with the outlet joint, the third end of the first three -way pipe and the second three -way pipe is provided with shunt joint, two measuring pipes are connected between two shunt joints.

[0005] Preferably, a connecting piece is further arranged between the first end of the first three -way pipe and the second three -way pipe.

[0006] Preferably, one side of the closed core away from the third end extends to the second end, so that the first end forms an elbow.

[0007] Preferably, the shunt joint is provided with two shunt chambers symmetrically arranged about the central axis of the shunt joint, and the shunt chamber is provided with a measuring pipe interface.

[0008] Preferably, the central axes of the inlet joint and the outlet joint are collinear.

[0009] The utility model discloses a beneficial effect is: utilize the closed core and the shunt connector to reform the tee pipe, reach the effect of replacing the shunt body, again connect two reformed tee pipes import, export connector and measuring pipe and form the mass flowmeter, the tee pipe can adopt the standard spare from the market direct purchase, only need to machine the closed core and the shunt connector, do not need to open the mould casting shunt body, effectively reduce the production cost.
