Herein, the background art relating to the present invention is provided, and they are not necessarily referred to as known arts.

Gas is convenient and clean compared to other fuels, and has many advantages such as high combustion efficiency. Therefore, it can be used in various fields such as thermal power generation, steel making, steel making, petrochemical, synthetic chemical, ceramics, It is widely used and is handled.

Such a gas is stored in a gas tank, a variable pressure vessel, or other storage container having a considerable capacity so as to be able to cope with load fluctuation, and then is transferred through a pipe network.

Since the gas leakage through the pipe network leads to a major accident, the pipe network to which the gas is supplied and the combustion apparatus in which the gas is burned need to check the leakage of the gas from time to time to prevent safety accidents in advance.

In this connection, the Korean Registered Utility Model No. 20-0302467 discloses a construction in which the intermediate valve 1 and the transparent water receiving cylinder 3 are integrally formed, the check valve 2 having the spring 4 therein, (Refer to FIG. 1) in which a check valve 2 is operated when a user desires to confirm the leakage of gas (see FIG. 1).

Korean Utility Model Laid-Open No. 20-2008-0005098 discloses that a button 60 is formed outside the checking unit 140 and the button 60 is integrally connected to the button 60 inside the checking unit 140, A piston 70 is formed to move up and down according to the pressing of the piston 70. A piston 70 is connected to the piston 70 by a moving path 110 connecting and isolating the supply passage 80, And a gas pipe 130 configured to be submerged in the water of the water receptacle 30 is provided at a lower side of the transfer passage 110 And is configured to select the inflow of the gas in the gas supply passage 80 according to the adjustment of the button 60 so that the gas can flow into the gas pipe 130 to check whether the gas flows out from the gas outlet 41 side (Refer to FIG. 2).

Korean Registered Utility Model No. 20-0302467 has a problem that when the elasticity of the spring 4 is reduced due to repeated use of the check valve 2, the gas leakage detection operation by the check valve 2 becomes impossible, Since the intermediate valve 1 and the water receiving tube 3 are directly connected to each other, the water in the water receiving tube 3 can flow back to the intermediate valve 1 side.

Korean Unexamined Utility Model Publication No. 20-2008-0005098 discloses that although the risk of backward flow can be reduced by the piston portion 70, since the operation of the button 60 is supported by the spring, The problem still remains.
