Embodiment Construction

[0029] The present invention will be described in detail in conjunction with accompanying drawing now. This figure is a simplified schematic diagram only illustrating the basic structure of the present invention in a schematic manner, so it only shows the components relevant to the present invention.

[0030] Such as Figure 1-2 As shown, the present invention provides a flowmeter equipped with a uniform flow sleeve, which includes a main body 1 , a measuring assembly 2 disposed on the main body 1 and a uniform flow sleeve 3 disposed in the main body 1 .

[0031] Such as Figure 2-3 As shown, the main body 1 includes a connecting shell 11, a first joint 12 provided at one end of the connecting shell 11, and a second joint 13 provided at the other end of the connecting shell 11. A channel 121 is opened axially through the first joint 12, and the second The second joint 13 is axially penetrated with a channel 2 131, and the connecting shell 11 is provided with a fluid channel ...

Abstract

The flow uniformizing sleeve comprises a first flow uniformizing piece and a second flow uniformizing piece arranged opposite to the first flow uniformizing piece, the first flow uniformizing piece comprises a plurality of first flow uniformizing pieces, a plurality of first flow uniformizing holes are formed in the first flow uniformizing pieces, and a plurality of second flow uniformizing holes are formed in the second flow uniformizing pieces. The first flow uniformizing piece comprises a plurality of first flow uniformizing pieces, the first flow uniformizing pieces are overlapped in the mode that the first flow uniformizing holes correspond to one another in a one-to-one mode, the second flow uniformizing piece comprises a plurality of second flow uniformizing pieces, a plurality of second flow uniformizing holes are formed in the second flow uniformizing pieces, and the second flow uniformizing pieces are overlapped in the mode that the second flow uniformizing holes correspond to one another in a one-to-one mode. According to the flow uniformizing sleeve, fluid in an original unstable state is screened through the first flow uniformizing piece and the second flow uniformizing piece, so that turbulent flow in the original unstable state of the fluid is converted into multiple beams of laminar flow in a stable state, and the preparation process is simple; therefore, the flow meter provided with the flow equalizing sleeve can obtain accurate flow data in subsequent measurement.

Description

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