Embodiment Construction

[0029] The present invention will now be described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, and only illustrates the basic structure of the present invention in a schematic manner, so it only shows the structure related to the present invention.

[0030] like Figure 1-2 As shown, the present invention provides a flowmeter equipped with a flow jacket, comprising a main body 1 , a measurement assembly 2 arranged on the main body 1 , and a flow jacket 3 arranged in the main body 1 .

[0031] like Figure 2-3 As shown, the main body 1 includes a connecting shell 11, a first joint 12 arranged at one end of the connecting shell 11, and a second joint 13 arranged at the other end of the connecting shell 11. The first joint 12 has a channel 121 axially penetrating through it. The second joint 13 is provided with a channel 2 131 axially penetrating through it. The connecting shell 11 has a fluid channel 111 and an inner ca...

Abstract

The invention discloses a flow uniformity sleeve and a flowmeter equipped with a flow uniformity sleeve, comprising a first flow uniformity piece and a second flow uniformity piece opposite to the first flow uniformity piece, the first flow uniformity piece includes multiple a plurality of first flow equalizers, a plurality of first flow equalizers are provided with a plurality of first flow equalizers, and a plurality of first flow equalizers are superimposed on each other in a one-to-one correspondence with the first flow uniformity holes, so The second flow equalizer includes a plurality of second flow equalizers, and a plurality of second flow even holes are opened on the plurality of second flow equalizers. One-to-one correspondences are superimposed on each other. The flow uniforming sleeve of the present invention sieves the originally unstable fluid through the first flow evening piece and the first flow evening piece, so that the fluid is converted from the turbulent flow in the original state into a multi-beam stable laminar flow, and the preparation The process is simple, so that the flow meter equipped with the uniform flow sleeve can obtain accurate flow data in the subsequent measurement.

Description

technical field [0001] The invention relates to the technical field of fluid monitoring, in particular to an even flow sleeve and a flowmeter equipped with the even flow sleeve. Background technique [0002] Flowmeters are instruments used to measure fluid flow through pipes or open channels, mainly for measuring volume flow or mass flow, and are widely used in semiconductor, photovoltaic, optical fiber, pharmaceutical and industrial automation industries. A typical flow meter for special gas measurement in the semiconductor industry mainly includes components such as uniform flow sleeve and flow sensor. Its working principle is: the fluid flows into the flowmeter through the inlet, firstly rectifies the fluid in the turbulent flow state through the uniform flow sleeve, converts it into a laminar flow state, and then divides the fluid, part of it enters the flow sensor measurement pipeline, and the rest is directly Flow into the main channel, the last two fluids are collect...
