Description

Flow meter

Technical Field

The present invention relates to a flow meter, and more particularly, to a flow meter that displays a flow rate of a fluid.

Background

In this specification, unless otherwise indicated, what is described in this section (section) is not admitted to be prior art to the claims of the present application, and what is contained in this section (section) is not admitted to be prior art.

The flow meter is used to measure the flow rate of a fluid such as air or water.

Conventional gas flow meters have various forms such as a glass tube float flow meter, a differential pressure flow meter, a panel float flow meter, a metal tube float flow meter, and a turbine flow meter depending on the purpose of use.

In a conventional flowmeter for measuring a flow of a fluid, an inlet through which the fluid flows in and an outlet through which the fluid flows out are formed on one side of a gauge (gauge), and a ball is provided in the gauge and moves by the fluid, thereby indicating a scale formed on the gauge to measure the flow rate.

However, as shown in fig. 7, the conventional flow meter includes: a case 100' made of a transparent material and having a gauge marked with scales and in which a float can vertically move formed on a front surface thereof; coupling portions 142 ', 144 ' formed at both sides of the case 100 ', respectively; and an installation part 300 'having both ends formed with an outlet 220' and an inlet 240 'coupled to the coupling parts 142' and 144 ', respectively, and installed on the rear surface of the case 100'.

However, in the prior art, distortion occurs due to thermal deformation in the process of welding the inlet 240 ' and the outlet 220 ' to the mounting portion 300 '.

If the twisted inlet 240 'or outlet 220' is coupled to the coupling parts 142 'and 144', the packing (packing) attached to the outer surfaces of the inlet and outlet cannot be uniformly adhered to the inner circumferential surface of the coupling part of the case due to the twisted angle, and thus the airtight state cannot be maintained and leakage occurs.

In particular, in the process of assembling the inlet port 240 ' or the outlet port 220 ' by screwing (screwing) the nipple (nipple), when a strong clamping force is applied, the mounting portion 300 ' is affected and twisted, and the inlet port 240 ' and the outlet port 220 ' are not correctly coupled to the coupling portions 142 ' and 144 ', which causes leakage.

Preferred embodiments are described in detail below based on the drawings as follows.

The embodiments described below are described in detail for facilitating the implementation by those skilled in the art to which the present invention pertains, but the technical spirit and scope of the present invention is not limited to these.

In addition, the sizes and shapes of the components shown in the drawings may be exaggerated for clarity and convenience of description, and terms specifically defined in consideration of the structures and actions of the present invention may be different depending on the intentions and conventions of a user and a reader, and therefore, the definitions of the terms should be explained based on the entire contents in the present specification.

FIG. 1, which is attached hereto, is a perspective view of the front of a flow meter illustrating an embodiment; FIG. 2 is a perspective view showing the back of the flow meter of the embodiment; FIG. 3 is an exploded perspective view of the flow meter illustrating an embodiment; FIG. 4 is a combined side view of the flow meter of the embodiment; FIG. 5 is a bottom view of the combination of the flow meter of the embodiment; fig. 6 is a combined cross-sectional view showing the flow meter of the embodiment.

As shown in fig. 1 to 5, the flow meter a of the embodiment includes: a case 100 formed of a transparent material and having a gauge 120, which is provided with a scale on the front surface thereof and in which a float (not shown) moving due to buoyancy is inserted; an upper coupling portion 142 and a lower coupling portion 144 formed at the upper and lower portions of the case 100, respectively; and a mounting part 300 having an outlet 220 and an inlet 240 coupled to the upper coupling part 142 and the lower coupling part 144, respectively, formed at both ends thereof and mounted to the rear surface of the case 100.

The housing 100 is made of a transparent material, and is usually made of a polycarbonate material or the like.

The gauge 120 includes: a level bar 122 formed in a straight line on the front surface of the housing 100; a pipe 124 having scales marked on both sides of the level 122 and formed inside in such a manner as to correspond to the level 122, and a float inserted into the pipe 124.

The float is adapted for beads.

An upper coupling portion 142 and a lower coupling portion 144 are formed at both sides of the case 100, respectively. The upper and lower portions are defined with reference to when the housing 100 is vertically formed.

The upper coupling portion 142 and the lower coupling portion 144 are respectively formed in a cylindrical shape, communicate with both ends of the pipe 124, respectively, have inner circumferential surfaces coupled to the outlet 220 and the inlet 240, respectively, and are tightly coupled to the inner circumferential surfaces of the upper coupling portion 142 and the lower coupling portion 144 by providing a gasket 260 on the outer circumferential surfaces of the outlet 220 and the inlet 240.

The mounting portion 300 is formed by connecting a first member 310 and a second member 320 having a predetermined length.

The first member 310 has a side wall formed at a side surface thereof and a section having an n-shape, one side of which is coupled with the lead-out opening 220, the other side of which is formed with an insertion portion 314, and the insertion portion 314 is formed with an adjustment hole 340 having a length.

The second member 320 has a side wall formed at a side thereof and a "Π" shape in cross section, one side of which is combined with the introduction port 240, and the other side of which is formed with a tongue piece (tongue)322 inserted into the insertion portion 314 of the first member 310, and the tongue piece 322 is formed with a screw hole 323 corresponding to the adjustment hole 340.

The tongue piece 322 has a step 326 formed by bending one end of the second member 320 to one side.

The height of the step 326 corresponds to the thickness of the first member 310.

Therefore, the tongue piece 322 is inserted into the insertion portion 314 of the first member 310 and closely attached to the bottom surface of the first member 310, and the surfaces of the first member 310 and the second member 320 can maintain the same height.

On the other hand, the first member 310 and the second member 320 are formed with an adjustment portion to enable adjustment of the interval.

The adjusting portion includes an adjusting hole 340 formed at one side of the first member 310, a screw hole 323 formed at one side of the second member 320 to correspond to the adjusting hole 340, and a screw 360 fastened through the adjusting hole 340 and the screw hole 323.

Accordingly, the distance between the first member 310 and the second member 320 can be adjusted in a state where the screw hole 323 and the adjustment hole 340 are aligned after the tongue piece 322 of the second member 320 is inserted into the insertion portion 314 of the first member 310, and the position where the inlet 240 and the outlet 220 are coupled, that is, the position where the upper coupling portion 102 and the lower coupling portion 104 are accurately aligned with the positions of the both sides of the housing 100 can be adjusted by rotating the first member 310 and the second member 320 vertically at a slight angle.

Further, when the inlet 240 and the outlet 220 are welded to the first member 310 and the second member 320, respectively, although there is a possibility that the plate portions of the first member 310 and the second member 320 are distorted due to thermal deformation, the distortion can be corrected by adjusting the interval between the adjustment hole 340 and the screw hole 323 and the lateral deviation, and the inlet 240 and the outlet 220 can be accurately coupled to the upper coupling portion 142 and the lower coupling portion 144.

On the other hand, the first member 310 and the second member 320 have

fixing holes

319 and 329 formed in side walls thereof, respectively, and the first member 310 and the second member 320 can be integrated with the casing 100 by coupling bolts 382 coupled to the side surfaces of the casing 100 to the

fixing holes

319 and 329.

In order to test the flow meter of the example, a leak test was performed on the existing known product and the modified example (modified product), and the results are shown in the following [ table 1 ].
