Abstract

The present invention relates to a gas leakage check valve.

In more detail, the gas leakage check valve is formed on one side of the intermediate valve and is formed integrally with the intermediate valve to form a check valve for checking the leakage state of the gas supplied to the gas apparatus such as a gas burner through the intermediate valve. In particular, to provide a horizontal gas leakage check valve configured to be installed horizontally to check the gas leakage state by the gas bubbles generated in the water container.

In general, the method of checking the leakage state of gas is to check the bubble caused by the gas leak by visually inspecting the bubble caused by the gas leakage by burying the connection part of the valve and the gas device with the foam using detergent. Sensors using sensors have been installed separately. However, due to the high cost of installing the detector, it is difficult to install in a normal home, so many homes do not check it by using a foaming method using detergent manually or perform a gas leak test at all. Therefore, in order to solve this problem, it is necessary to develop a device that can be easily integrated with the intermediate valve to check the gas leakage state. Looking at the gas leakage check valve designed to meet such a demand, FIG. Integrate the gas leak checker into a single device to be able to check the gas leak state if necessary,

The water tank 20 of the transparent material is mounted on the conventional intermediate valve 10 to contain a certain amount of water, and the gas introduced from the gas supply port 40 passes through the check valve 70. When passing through the gas leaks as much as the amount of gas leaks when the gas leaks, the check valve 70 is a one-touch method using a spring to check the gas droplets with the naked eye, the gas supply port 40 and the water tank ( There has been a gas leakage check valve for checking gas leakage by opening or closing the connecting passage 50 with 20).

However, since the material in the water container is a liquid, it must be installed vertically in a vertically installed pipe or hose so that the gas pipe is contained in the liquid so that the gas can be checked and installed in a horizontally installed pipe or hose. There has been a problem that can not be confirmed for leaks.

The purpose is to provide a horizontal gas leakage check valve that increases the diversity as a product by being configured so that even if installed horizontally so that it can be installed in the horizontal pipe or hose.

Hereinafter, with reference to the accompanying drawings to achieve the above object in more detail,

1 is a cross-sectional view of a conventional gas leakage check valve, Figure 2 is a cross-sectional view showing an open state of the intermediate valve of the horizontal gas leak check valve of the present invention, Figure 3 is the middle of the horizontal gas leak check valve of the present invention A cross-sectional view showing the action when the valve is closed,

Referring to the operation of the conventional gas leak check valve as shown in Figure 1 when the piston 61 is pulled by pressing the switch 60 integrally or connected with the piston 61 reciprocating by the spring in a state in which the intermediate valve is closed; When the connecting passage 50 connecting the check valve 70 and the water tank 20 is opened so that the gas entering the gas supply port 40 flows toward the check valve 70 and no gas leaks from the gas appliance or the connecting part. When the gas does not flow and stops, and no change occurs, when the gas is leaking, the gas discharge port 41 passes through the check valve 70 and the water tank 20 by the amount of gas leaking into the gas supply port 40. As it flows into the water pipe 20, the amount of gas is generated by the amount of gas leak is to confirm that the gas is leaking to the naked eye.

Thus, the present invention has a structure in which the water tank 20 is formed below the intermediate valve 10 and the gas pipe 30 connected to the gas supply hole 40 is contained in the solution inside the water tank 20.

It is composed of a gas pipe 30 connected to the gas supply port 40 and the gas pipe 30 contained in the solution inside the water tank 20 and the moving path 80 connected to the gas discharge port 41.

Therefore, looking at an embodiment of the horizontal gas leakage check valve configured as described above,

When the gas is used as shown in FIG. 3, and the gas valve 30 is closed as shown in FIG. 3 while the intermediate valve 10 is opened in FIG. 2, the gas is a gas pipe 30. To the side. At this time, if there is no leakage of gas, since there is no difference in pressure between the front and rear ends based on the intermediate valve 10, the gas flowing toward the gas pipe 30 through the gas supply port 40 pushes the solution inside the water tank 20. I can't. However, if gas leak occurs at any part of the rear end of the intermediate valve 10, the pressure at the rear end of the intermediate valve 10 is lowered and the gas supplied through the gas supply port 40 in front of the intermediate valve 10 is relatively low. The pressure is high. Therefore, the pressure supplied through the relatively high gas supply port 40 pushes the solution in the water container 20 through the gas pipe 30 to generate droplets, and the gas discharge port 41 through the moving path 80. It will flow in the direction of leakage will be able to check the gas leakage with the naked eye.

Therefore, the horizontal gas leak checker according to the present invention configured as described above can be installed in a horizontal pipe or a hose to improve the problem that the product can not be installed because the installation specification is not suitable in homes and restaurants that need to check the gas leak. The effect is a great design.
