Embodiment 1

[0046] like figure 1 As shown, the present embodiment provides a magnetic field shield that is easy to assemble and disassemble, and the magnetic field shield is used to be sleeved on the periphery of the flowmeter 100 to shield the magnetic signal of the surrounding environment of the flowmeter 100; the magnetic field shield includes: shielding Cover 1, first cuff 2, second cuff 3, and third cuff 4.

[0047] like figure 2 As shown, the shielding cover 1 includes a detachable first cover body 11, a second cover body 12, and a third cover body 13; the combination of the first cover body 11, the second cover body 12 and the third cover body 13 contains Two cylindrical cavities, wherein the horizontal part is the first cylindrical cavity, and the vertical part is the second cylindrical cavity; the first cylindrical cavity and the second cylindrical cavity are connected in an inverted "T" shape; along the Half-cut the first cylindrical cavity on the horizontal plane, and the ob...

Embodiment 2

[0057] like Figure 7 As shown, the difference between this example and Embodiment 1 is: the magnetic field shielder provided in the embodiment of the present invention for easy disassembly also includes a limit bolt 6; 1. Bolt holes 61 are set on the sides of the left second hoop portion 31 and the right second hoop portion 32, and the bolt holes 61 are located on the unthreaded part of the first hoop 2 and the second hoop 3, and the limit bolt 6 The bolt body is screwed into the shielding case 1 through the bolt hole 61 along the radial direction of the cross-sectional circle of the first cylindrical cavity in the shielding case 1 .

[0058] The function of the limit bolt 6 is to press against the pipelines on both sides of the flowmeter 100. Although the first ferrule 2 and the second ferrule 3 can limit the shaking of the magnetic field shield after installation, they cannot limit the movement of the magnetic field shield along the direction of the pipeline. slide. After...

Embodiment 3

[0061] like Figure 9 As shown, on the basis of Embodiment 2, the magnetic field shielding device of this example further adds a limit clamp 7; the limit clamp 7 is arc-shaped, and the limit clamp 7 is arranged on the first hoop 2 and the second Inside the ferrule 3, it is used to tightly install the pipeline of the flowmeter 100; the number of limit clamps 7 in the first ferrule 2 and the second ferrule 3 is two, and the two are symmetrically arranged; the limit clamp 7 The outer side is provided with a threaded sleeve 71 for connecting the limit bolt 6 .

[0062] In this embodiment, in order to increase the position-limiting effect of the bolts, a position-limiting clamp 7 is further added in the first ferrule 2 and the second ferrule 3 . When in use, when the limit bolt 6 is tightened inward, the limit clamp 7 is squeezed inward, and the limit clamp 7 will hold the pipes on both sides of the flowmeter 100 during the inward feeding process, so that the magnetic field shield...

Abstract

The invention belongs to the technical field of instruments and meters, and particularly relates to a magnetic field shielding device convenient to disassemble and assemble and an assembling method thereof. The magnetic field shielding device is used for being arranged on the periphery of the flow meter in a sleeving mode and shielding magnetic signals of the surrounding environment of the flow meter. The magnetic field shielding device comprises a shielding cover, a first hoop sleeve, a second hoop sleeve and a third hoop sleeve. The shielding case comprises a first case body, a second case body and a third case body which are detachable; the first hoop sleeve is connected with the left end of the shielding cover; the first hoop sleeve comprises a left first hoop sleeve part, a right first hoop sleeve part and a fastener; the second hoop sleeve is connected with the right end of the shielding cover; the second hoop sleeve comprises a left second hoop sleeve part, a right second hoop sleeve part and a fastener; the third hoop sleeve is connected with the upper end of the shielding cover; the third hoop sleeve comprises a left third hoop sleeve part, a right third hoop sleeve part and a fastener. The magnetic field shielding device is very convenient to disassemble and assemble, can be applied to a large number of existing products, and is very good in electromagnetic shielding effect.

Description

technical field [0001] The invention belongs to the technical field of instruments and meters, and in particular relates to a magnetic field shielder which is easy to assemble and disassemble and an assembly method thereof. Background technique [0002] The flowmeters currently on the market are mainly electromagnetic flowmeters, turbine flowmeters, and vortex flowmeters. These flowmeters can be applied to flow detection of different fluids according to their own structures and principles. Among them, taking the latter two as examples, a turbine flowmeter is an instrument that uses a multi-blade turbine to measure the average flow of a fluid and thereby calculate the flow or total flow. The vortex flowmeter is designed and manufactured according to the Karman vortex principle. The flow rate is measured using the principle of fluid oscillation. When the fluid passes through the vortex conveyor in the pipeline, the triangular column vortex generator generates two rows of vor...
