Description

[0001] The present invention relates to a flow measuring device for a storage tank,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flow rate meter for a storage tank for measuring a residual amount of a fluid such as fuel oil stored in a storage tank and an operator can easily determine the level of the storage tank by the naked eye and accurately measure the residual amount in the storage tank .

In general, various kinds of industrial tanks are equipped with various kinds of storage tanks for storing fluids, and when the residual amount is not easily visually recognized because it is embedded on the ground like a gas tank of a gas station, a flow tester for storage tanks is used do.

The most basic structure of this flowmeter is that the operator visually confirms the degree of liquid immersion when the measuring device is immersed in the storage tank and taken out.

However, when the fluid contained in the storage tank has volatile characteristics like gasoline, there is a problem that accurate measurement is difficult because the fluid is volatilized in the process of inserting and removing the flow meter. To solve this problem, a hose is provided in the flow meter, A flow meter equipped with a valve has been proposed.

When the flowmeter is inserted into the storage tank, the valve at the lower end is opened, and the fluid is injected into the hose to the same level as the water level of the storage tank. In this state, the flowmeter is taken out and the flow rate is measured.

At this time, a meter having a mark scale is provided on the side of the flow meter to measure the residual amount of the storage tank.

However, since the problem of this is that the direction in which the level of the fluid contained in the hose is confirmed and the direction in which the indicator of the measurer is displayed are different from each other, the operator has to check the level by turning the flowmeter, so that the measurement is very cumbersome, There is a problem that accurate measurement is difficult because the display scale of the measurer is confirmed.

In order to prevent loss due to volatility, the diameter of the measuring hole for inserting the flow meter is formed to be very small. In order to fit the limited diameter of the measuring tank, the diameter of the flow meter itself must be small. It can not be formed largely, and it is difficult for the measurer to easily recognize it.

Particularly, in the case of storage tanks buried in the ground, the measuring area for measuring the residual amount is often provided on the edge so as not to interfere with the operation in the industrial field. In order to make an accurate measurement using a small- There are many difficulties.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 through 3, the present invention provides a hose assembly comprising a frame body 100, a hollow inflow hose 200 mounted on the frame body 100 for temporarily storing a fluid to be measured, 200 and a measuring device 400 for measuring the level of the fluid temporarily stored in the inflow hose 200. The inflow hose 200 includes a frame body 100, And an inlet hose 200 filled with a fluid is arranged in the front of the tester 400. The refractive index of the measuring tube 400 is adjusted by the refraction of light, Can be enlarged and displayed.

The frame body 100 constitutes the body of the flowmeter. The frame body 100 may be formed by extrusion-molding a long, lightweight metal material such as aluminum, which is lightweight and durable.

The inner portion 120 may be formed on the front of the frame body 100 so that the inlet hose 200 and the measurer 400 can be assembled by vertically inserting them upward and downward.

The shape of the inner portion 120 is formed in the shape of an "∩" shape in which the inner wall 124 is formed adjacent to both the inner surface 122 and the inner surface 122 when viewed from the plane, The inflow hose 200 can be assembled successively.

At this time, the depth of the inside surface 122 is made such that the surface of the inflow hose 200 does not protrude forward of the frame body 100 in a state in which the measurer 400 and the inflow hose 200 are inserted desirable.

In addition, the frame body 100 is reinforced without bending the shape of the frame body 100, and the flow meter is inserted into a measuring port (which is inserted into the tank and connected to the outside of the tank) A plurality of through holes 125 may be further provided to mitigate the impact generated when the side of the flowmeter collides against the inner wall of the measurement port when the flowmeter is drawn out from the measurement port. The frame body 100 may be integrally molded by extrusion molding.

As described above, the inflow hose 200 is provided in the inner portion 120 of the frame body 100 and can be used as a fluid to be measured, for example, a fuel oil such as gasoline or diesel in a gas station, And an inflow port 210 is provided at the lower end of the inflow hose 200 to allow the fluid in the storage tank T to flow into the inflow hose 200. [

The inflow hose 200 is made of a transparent tube so that the fluid filled in the inflow hose 200 can be easily visually inspected from the outside and can be provided with a hard transparent tube such as glass, It is preferable to use a flexible tube made of synthetic resin or the like.

The inflow hose 200 is inserted into the frame body 100 so that the fluid hits the inflow hose 200 at the same level as the fluid in the storage tank T by the atmospheric pressure The upper end of the inflow hose 200 can be kept open.

Further, at the lower end of the inflow hose 200, an opening / closing means 300 for blocking or opening the flow path connected to the inflow hose 200 is provided.

The opening and closing means 300 includes a valve 310 installed in the cylinder 310. The flow meter is inserted into the storage tank T so that when the lower end of the flowmeter is pushed or dropped from the bottom of the storage tank, The opening and closing means 300 is installed in communication with the inlet 210 provided at the lower end of the inlet hose 200 so as to fill the fluid or to supply the filled fluid It is possible to discharge it.

7, the valve 320 is elastically fixed to the cylinder 310 having the flow path 315 so as to have a repulsive force by the elastic element 330, When the flow meter is lifted up, the flow path 315 is blocked by the valve 320, so that the fluid can flow through the valve And the fluid is temporarily stored in the inflow hose 200.

In addition, the opening and closing means 300 may further include a buffer 340 for canceling an impact generated when the lower end of the valve 320 directly contacts the bottom of the storage tank.

The buffer 340 is elastically fixed to the lower end of the cylinder 310 with a spring 345. The flow meter is inserted into a measuring port of the storage tank T so that when the flow meter falls, It is possible to minimize the shock transmitted to the valve 320 by reducing the impact by the spring 345 by abutting against the bottom of the tank first, thereby preventing the valve 320 from being damaged or broken.

The measuring instrument 400 inserted into the inner portion 120 of the frame body 100 is provided with a display scale 410 at regular intervals and measures the level of the fluid temporarily stored in the inlet hose 200 The storage amount of the fluid stored in the storage tank T can be inversely calculated.

At this time, the measurer 400 and the inflow hose 200 are assembled by inserting the measurer 400 in the inner part 120 of the frame body 100 so that the measurer 400 is disposed inside, and the cylindrical inflow A hose 200 is disposed.

6, when the fluid is received in the inflow hose 200, the display scale 410 of the measurer 400 is reflected by the inflow hose 200 due to the refraction of light as shown in FIG. 6, And the water level of the inflow hose 200 is enlarged and the flow rate can be accurately determined by using the displayed scale.

At this time, the measurer 400 allows the measurer 400 to be disposed within the rear focal distance of the inflow hose 200 on the basis of the surface curvature of the inflow hose 200, so that the display scale passes through the inflow hose 200, When displayed, the image is not distorted but is enlarged and displayed forward by the refraction phenomenon.

That is, when the measurer 400 is disposed at a position exceeding the focal distance with respect to the surface curvature of the inflow hose 200, the image is distorted or the image is inverted, 200 are positioned so as to be relatively closer to each other than the focal distance in which the light is refracted and concentrated in a state in which the fluid is contained.

The structure in which the measurer 400 is fitted to the frame body 100 includes a guide groove 126 for fixing both ends of the measurer 400 to the inner portion 120 of the frame body 100 The measurer 400 can be easily assembled by inserting the measurer 400 in a sliding manner along the longitudinal direction of the frame body 100.

Since the both sides of the tester 400 are supported by the guide grooves 126 in the state where the tester 400 is inserted into the frame body 100, no flow occurs at all and even when an external shock occurs, 400 can be maintained and the accurate level measurement can be performed.

The interior portion 120 of the frame body 100 may be provided with a seating groove 128 corresponding to the outer diameter of the inflow hose 200 so that the inflow hose 200 is kept upright and does not flow .

The mounting groove 128 is formed in the same shape as the outer diameter of the inflow hose 200 so as to be in close contact with the outer circumference of the inflow hose 200 and to prevent the inflow hose 200 from tilting or being disengaged from the frame body 100 It is preferable to manufacture such a structure.

The frame body 100 may further include a grip portion 500 used as a handle. The frame body 100 may include a grip portion 500 for holding the grip portion 500. [ A fitting protrusion 504 is formed on the lower side of the grip portion 500 in correspondence with the seating groove 128 formed in the inner portion 120 so as to block the upper portion of the inner portion 120 in which the inlet hose 200 is assembled, It is possible to assemble the grip portion 500 by inserting the hose so as not to detach the hose.

At this time, the seating groove 128 and the fitting protrusion 504 may be assembled in such a manner as to form a helical portion corresponding to each other and to be fitted by turning, or may be assembled in at least one of the inner diameter of the seating groove 128 and the outer diameter of the fitting projection 504 A plurality of protruding ribs are formed and assembled by forcible fitting so that the surfaces where the seating groove 128 and the fitting protrusions 504 are in contact with each other are welded together by frictional force,
