The present invention relates to an LPG gas leak inspection device that enables the user to easily check and check the leakage of gas on the demand side including the intermediate valve when using the LPG gas.

In more detail, the intermediate valve is installed in a sealed oil tank containing a certain amount of crepart oil (hereinafter referred to as transparent oil) in which the intermediate valve has excellent fire resistance, ice resistance, mixing with other substances, and little self-evaporation property. However, the operation lever of the intermediate valve protruding to the outside and the pressure button which is suddenly fused to the bottom of one side of the oil tank lift and move the transparent oil in the sealed oil tank to open and close the outlet of the communication pipe in the sealed oil tank as transparent oil. (B) When gas leaks to the receiving side, it is possible to easily check and check the bubble phenomenon according to the pressure flow of gas at the transparent flow rate closing the outlet of the communication pipe through the sight window installed on the bottom of the oil tank.

Conventionally, a gas leak alarm device that uses an electronic circuit using a semiconductor component to emit an alarm sound when gas is leaked is used for a similar purpose to the present manuscript. However, since it uses an electronic circuit, it cannot be used during a power failure. In particular, according to the surrounding environment of the installation site, malfunctions and breakdowns of the circuit were frequent, so that the leak detection could not be satisfactorily effected. Also, due to the high price, the defect was not practically used.

The present invention, in view of the above-mentioned conventional defects as described above, the user of the gas supply hose is installed in a closed oil tank in which an appropriate amount of transparent oil is loaded in the intermediate valve, and the transparent oil charged in the inside of the sealed oil tank is externally manipulated. By moving up and down, the transparent oil opens and closes the communication outlet inside the sealed oil tank. If gas leaks to the intermediate valve or receiving side when the gas is not used, the oil flows to the pressure gas at a transparent flow rate that blocks the gas flow port. The phenomenon caused by the bubble is easily checked through a see-through window installed on the front side of the closed oil tank, so that it can be easily checked and used when the gas is not used. The detailed description will be made according to the accompanying drawings.

Gas container 1 into which compressed liquefied gas (LPG) is infiltrated, a supply hose (2) (2 ') for guiding supply thereof, an accommodating part (3) using the same, and an intermediate part placed in place of the supply hose (2). In installing the gas leak check device in the opening structure of the LPG gas provided with the valve 4, one side of the sealed oil tank 5 into which the above-described intermediate valve 4 infiltrates a certain amount of transparent oil a. The weight body 6 which is mounted on the upper part and whose outlet 4 'and the operation lever 4 "are exposed to the outside, and is lifted and interlocked by the opening and closing operation of the operation lever 4" directly under the intermediate valve 4; ) Is installed so that the communication hole (7 ') is formed at the lower end, and the gas inlet chamber (8) communicating with the external inlet (8') is formed at the upper end thereof as the communication tube (9). In order to communicate with the confirmation chamber 10 having a reflecting plate (10 ') formed in the center portion, the sight glass (5') is installed on the front of the sealed tank (5) of the confirmation chamber 10 and opened The lower part of the pipe 9 is formed with a communication chamber 11 and a communication chamber 12 'having a communication hole 12', and the entrance chamber 12 has a crimp formed with a pressurized button 13 'protruding outward from the bottom. By incorporating the cylinder 13, the transparent oil a in the sealed oil tank 5 is moved up and down in accordance with the opening and closing operation of the operating lever 4 "and the pressing button 13 'as transparent oil a. The outlet 9a of the communication tube 9 is to be opened or closed.

In the figure, reference numeral 14 denotes a gas range, and 14 'denotes an opening and closing cock.

The effect of this invention made as described above is demonstrated.

First, when the gas is used, the weight 6 to be interlocked according to the opening and closing operation of the operating lever 4 "is operated by operating the operating lever 4" of the sealed oil tank 5 in which the intermediate valve 4 is built in an open state. As shown in FIG. 2, the pressure supplied from the gas container 1 by allowing the transparent oil a introduced into the closed oil tank 5 to open the outlet 9a of the communication tube 9 as shown in FIG. The gas is supplied from the supply hose (2), the inlet (8 '), the gas inlet chamber (8), the communication tube (9), the check chamber (10), the intermediate valve (4), the outlet (4'), the supply hose (2)). Open the opening and closing cock 14 ′ of the gas receiving unit 3, that is, the gas range 14, to use the fire according to the use of gas, and first check the operation valve of the intermediate valve 4 when checking for gas leakage. (4 ") is operated in the closed state to check for gas leakage in the intermediate valve (4) part. In this case, since the operating lever (4") of the intermediate valve (4) is closed, the operation of the operating lever (4 ") Interlocked according to Since the polymer 6 is placed downward as shown in FIG. 4 (a), the transparent oil of the sealed oil tank 5 into which a certain amount of the transparent oil a is loaded is inevitably moved upwards to address the confirmation chamber 10. The outlet 9a of the communicating tube 9 located is in a closed state. If there is any abnormality in the part of the intermediate valve 4 and there is a small leak, the pressure gas applied from the gas container 1 Through the outlet (9a) of the communication pipe (9) continues to rise to the bubble state, the bubble state is made in the confirmation chamber (10) located in the center of the sealed oil tank (5) and the confirmation chamber (10) The reflector plate 10 'is located at the rear side of the sealed tank 5, and the viewing window 5' is installed at the front of the center of the sealed oil tank 5, so the inspector bubbles any leaks in the intermediate valve 4 through the viewing window 5 '. It is easy to check and check with the present conditions, and also includes the receiving side supply hose (2 '). At the time of leak check of the part 3, the operation lever 4 "of the intermediate valve 4 is operated in the open state, the weight body 6 is raised, and it is present in the lower end side of the sealed oil tank 5 When pressing the pressing button 13 'as shown in FIG. 4 (b), at this time, the transparent oil a in the sealed oil tank 5 is moved upward, thereby shielding the outlet 9a of the communication tube 9. When there is any leak in the receiving part 3 including the supply hose 2 ', the pressure gas infiltrated into the gas container 1 is bubbled through the outlet 9a of the communication tube 9 by the amount of leakage. As it is raised, it can be easily checked and checked through the see-through window 5 '.

Therefore, even if you are not an expert, all the gas users who handle LPG gas can easily check and check the gas leakage of all receiving parts including intermediate valves by simple manual operation. The gas can be handled and used to provide a great effect to prevent gas safety accidents.
