When the pin 44 descends due to the lowering of the fixed end of the lever 43, the opening and closing member 45 which seals the vertical passage 42a of the fixing member 42 and prevents the inflow of liquefied petroleum gas into the body 10 is prevented. And the at least one hole 46a through the body and fixed to the filling pipe 41 to allow a certain amount of liquefied petroleum gas to flow into the main body 10 to be opened and closed by the liquefied petroleum gas. An adjustment plate 46 is provided to prevent the member 45 from sealing the fixing member 42.

The upper portion of the filling pipe 41 is fixed to the upper portion of the main body 10 and its inlet is connected to the filling coupling 4 to supply the liquefied petroleum gas supplied from the filling coupling 60 into the main body 10. To guide.

As shown in FIG. 6, the fixing member 42 has a protrusion 42c protruding from the periphery of the body upper surface vertical passage 42a so that airtightness can be maintained when the opening and closing member 45 closes the vertical passage 42a. The support 42d is extended downward on both sides of the lower part of the body to fix the hinge pin P rotatably fixing the lever 43.

The pin receiving hole 42e passes through the fixing member 42 from the vertical passage 42b to the bottom of the body so that the pin 44 may be inserted into and close to the lever 43.

In addition, the assembly holes 42f are formed in the support 42d at both sides so that the hinge pins P can be inserted and fixed.

The opening / closing member 45 has a narrow upper portion so as not to close the hole 46a of the adjusting plate 46 when the lever 43 rises by the rotation of the lever 43, and the entire shape is conical. The seal 45b is inserted into the bottom receiving groove 45a so that the opening / closing member 45 is in close contact with the protrusion 42c of the fixing member 42 when the fixing member 42 is closed.

The level gauge 50 has upper and lower pipes 51 and 52 and upper and lower pipes respectively extending outward from upper and lower portions of the main body 10 so that liquefied petroleum gas can flow as shown in FIG. 7. 51 and 52, a gauge pipe 53 extending vertically outside the main body 10 and closed at both ends thereof to allow liquefied petroleum gas stored in the main body 10 to enter and exit the main body 10, and the gauge pipe. (53) The floating body 54 accommodated inside and descending in accordance with the liquid level of the liquefied petroleum gas, the permanent magnet 55 fitted to the upper portion of the floating body, and permanently in accordance with the lifting and lowering of the floating body 54 An annular display member 56 fitted to an outer diameter of the gauge pipe 53 so as to move up and down like a magnet 55 to indicate the liquid level of the liquefied petroleum gas inside the main body 10, and the display member 56 is disposed. The inner diameter is larger than the outer diameter of the display member 56 so as to be accommodated and protected therein. A transparent protective pipe 57 having a larger diameter and extending vertically so that both ends thereof are fixed to both ends of the gauge pipe 53, and the float 54 does not seal the outlet of the lower pipe 52; And an elastic member 58 for supporting the fluid 54 beyond the outlet of the lower pipe 52.

The floating body 54 has a stepped protrusion 54a protruding from the upper periphery so that the permanent magnet 55 can be assembled. In addition, the floating body 54 preferably pressurizes the liquefied petroleum gas of the gauge pipe 53 by its own weight so that its upper end position is equal to the liquefied petroleum gas level stored in the main body 10 so that its own weight is the same. .

The protective pipe 57 is composed of a transparent body to determine the position of the display member 56 to be elevated according to the permanent magnet (55).

The following describes the state of use of the subject innovation constructed as described above.

In the state before the liquefied petroleum gas is filled in the main body 10, the fixed end of the lever 43 is in close contact with the bottom surface of the fixing member 42, as shown in Figure 5a to prevent excessive downward rotation of the free end of the lever 43. .

In this state, when the liquefied petroleum gas is filled into the main body 10 by the filling coupling 60 to reach the float 43a, it becomes as shown in FIG. 3. This state is still before liquefied petroleum gas is overfilled.

At this time, the liquefied petroleum gas liquid level inside the main body 10 and the height of the upper end of the floating body 54 of the level gauge 50 are the same. In this state, when the liquefied petroleum gas is continuously introduced and the liquefied petroleum gas reaches the full position as shown in FIG. 4, the liquefied petroleum gas is no longer filled by the operation of the overfill prevention device 40, and the level gauge Reference numeral 50 denotes the liquid level.

This will be described in more detail as follows.

The liquefied petroleum gas introduced through the filling coupling 60 in the state in which the vertical passage 42a of the fixing member 42 is opened is a vertical passage of the hole 46a of the adjusting plate 46 and the fixing member 42. It is introduced into the main body 10 through the 42a and the horizontal passage 42b to fill the main body 10.

At this time, the liquefied petroleum gas is introduced at a high pressure, but a certain amount is introduced into the vertical passage 42b of the fixing member 42 while being reduced to low pressure while passing through the hole 46a of the adjusting plate 46. Therefore, when the liquefied petroleum gas is filled, the opening and closing member 45 does not seal the fixing member 42.

As the liquefied petroleum gas flows in and the liquid level rises, the floating body 54 of the level gauge 50 rises together due to the buoyancy of the liquefied petroleum gas, thereby indicating the filling position of the liquefied petroleum gas.

Subsequently, when the liquefied petroleum gas is filled to reach the full liquid position as shown in FIG. 4, the overfill preventing device 40 rises with the float 43a, and the free end of the lever 43 rises with the float 43a. In contrast, the fixed end is lowered, as shown in FIG. 5B.

The pin 44 is also lowered to the lower end of the fixed end so that the opening and closing member 45 located at the upper portion thereof closes the inlet of the vertical passage 42a of the fixing member 42 to automatically prevent the filling of the liquefied petroleum gas. .

It is preferable that the liquid filling position of the liquefied petroleum gas at this time is 843% to 90% of the storage capacity of the main body 10.

In this state, the liquid position gradually decreases due to the use of the liquefied petroleum gas, so that the lever 43 rotates and the opening / closing member 45 opens the vertical passage 42a of the fixing member 42 again. Filling the liquefied petroleum gas to be introduced into the main body 10 is repeated.

As such, when the filling and exhausting of the liquefied petroleum gas is repeated, the level gauge 50 accurately represents the liquid position of the liquefied petroleum gas.

The level gauge 50 is equipped with an elastic member 58 on the bottom surface of the gauge pipe 53, as shown in Figure 5a so that the floating body 54 opens the outlet of the lower pipe 52 at all times. Therefore, the liquefied petroleum gas introduced into the main body 10 is supplied to the gauge pipe 53 through the lower pipe 52 to push up the floating body 54.

As the liquefied petroleum gas is continuously introduced, the liquid position gradually rises, and as the float 54 rises together, the permanent magnet 55 attached to the upper portion of the float 54 rises. At the same time, the display member 56 rises together by the magnetic force of the permanent magnet 55 to indicate the liquid level of the liquefied petroleum gas.

Therefore, the user can know the liquid level of the liquefied petroleum gas by checking the rising and lowering position of the display member 56 because the protective pipe 57 is transparent.

The liquefied petroleum gas storage tank of the present invention constituted as described above can be installed in a narrow place because the main body of the cylindrical body is installed vertically, thereby providing simplicity of installation, and the overfill preventing device mounted on the upper part of the main body. Since it is detachably fixed from the outside, it is not necessary to form a separate passage for repair in the main body as in the prior art, thereby simplifying the main body manufacturing process and having the advantage of simplifying the repair in the event of an overfill prevention device failure. .

In addition, the liquefied petroleum gas can be filled according to the set capacity due to the installation of the overfill prevention device to reduce the waste caused by overfilling and has the advantage of safe filling.

The level gauge shows the level of the liquefied petroleum gas as the display member moves up and down, and has the advantage of accurately confirming the amount of the liquefied petroleum gas stored as the main body is installed vertically.
