Manifold device for high pressure mass flow meter and manifold assembly

Abstract

The invention relates to a manifold device (100) for a high pressure mass flow meter and a manifold assembly (10). The manifold device (100) comprises a rectangular body (110); the upper surface of the rectangular body (110) is provided with two sets of bosses (120) connected with measuring tubes (400); boss channels (121) are formed in the bosses; threaded holes (130) are formed in the two end faces of the rectangular body (110) respectively; and each threaded hole (130) is in fluid communication with the boss channels (121) in the corresponding set of bosses (120).

Description

technical field [0001] The present invention relates to manifold devices and manifold assemblies for mass flow meters. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] A Coriolis mass flowmeter (CMF for short) is a mass flow meter made using the principle of Coriolis force. density. figure 1 Shown is a current manifold assembly for a high-pressure mass flowmeter, which includes a manifold device 1, a pipe joint 2, and a measuring tube 3, wherein the manifold device 1 and the pipe joint 2 are connected by welding, which It is a sealing connection method adopted when common seals such as sealing rings are easily deformed and invalidated in high-pressure fluid. figure 2 and image 3 A manifold arrangement 1 is shown. The upper surface of the manifold device 1 is provided with a boss 11 connected with the measuring tube 3 , wherein a small hole 111...

AI Technical Summary

Problems solved by technology

To complete the above-mentioned welding structure, it is necessary to weld the welding end 21 of the pipe joint 2 and the welding parts 12 and 13 at both ends of the manifold device 1 in circles until the welding part is filled with welding material, which takes a long time to weld and consumes a lot of welding material

And because the diameters of the large holes 121 and 131 at both ends of the manifold device 1 are relatively large, in order to meet the pressure requirements, the manifold device 1 needs a thicker outer diameter, thus resulting in the oversized size of the entire manifold device 1

In addition, since the pipe joint 2 is a non-standard part, different sizes need to design different pipe joints 2, which will lead to an increase in materials
