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 button-type gas leakage check valve designed to meet such a demand, FIG. It is configured to check the gas leakage state if necessary by making a single device by integrating the gas leakage checker to the valve,

A gas container 30 of transparent material is mounted on a conventional intermediate valve 20 having a built-in fuse cock 10 to store constant water therein, and the gas coming from the gas supply port 40 checks the check valve 120. When passing through the water in the water tank (30), the amount of gas leaked by the amount of gas leaks when the gas leaks, so that the check valve 120 is a one-touch type using a spring so that the naked eye can check the gas droplets supply the gas There has been a button-type gas leak check valve that checks the gas leak by opening or closing the connecting passage 50 between the sphere 40 and the water tank 30.

However, the configuration as described above has too many parts inside the product, the operation and performance is not precise, occupies a lot of space, the body becomes larger than necessary, and the piston part takes a lot of time to process the appearance, appearance, There has been a problem that the value and productivity as a commodity such as weight falls.

In order to provide more accurate and easy operation for inspection, reduce weight, and configure the appearance and appearance of the product in a good way, it is possible to increase the value as a product and improve the productivity. There is this.

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

1 is a cross-sectional view of a conventional button-type gas leak check valve, Figure 2 is a cross-sectional view showing an open state of the intermediate valve of the cylindrical gas leak check valve of the present invention, Figure 3 is a cylinder type gas leak check valve 4 is a cross-sectional view showing the operation of the cylindrical gas leakage check valve of the present invention,

Looking at the operation of the conventional button-type gas leakage check valve as shown in Figure 1 by pressing the button 60 integrally or connected to the piston unit 70 reciprocating by the spring in the state in which the intermediate valve is closed to press the piston unit 70 When lowered, the supply passage 80 connecting the check valve 120 and the water tank 30 is opened so that the gas entering the gas supply port 40 flows toward the movement path 110 and the gas flows from the gas appliance or the connection part. When not leaking, the gas does not flow and stops, and no change occurs, but when gas is leaking, the gas flows through the passage 110 and the water tank 30 by the amount of gas leaking into the gas supply port 40. As it flows to the (41) will be confirmed that the gas is leaked to the naked eye by the gas droplets are produced by the amount of gas leakage in the water container (30).

Thus, the present invention is the button 60 is formed on the outside of the check unit 140 and the connection passage 50 of the water pipe 30 and the movement path 110 in accordance with the button is integrally connected or connected to the button therein. As a structure that can open and close

O-ring 4 (103) for opening and closing the movement path 110 and the discharge passage 90 to the connection and isolation action with the supply passage 80 is formed on one side of the piston portion is formed in accordance with the operation of the button piston (70) ) Is formed.

The movement path 110 is isolated from the inlet of the supply passage 80 by the position of the O-ring 2 (101) without pressing the button 60 formed on the outside so that the supply passage 80 and the movement path 110 It is formed so as not to flow through the water tank (30) to the gas discharge port (41).

The O-ring 4 103 is interlocked with the piston unit 70 and the piston unit at a position capable of blocking the connection passage 50 between the water tank 30 and the discharge passage 90 in a state in which the button 60 is not pressed ( 70) It is installed on the lower side to form a block so that the connection passage 50 between the water tank 30 and the discharge passage 90 in accordance with the operation of the button (60).

The moving path 110 is also configured to be connected to the gas pipe 122 submerged in the water filled in the water container 30 as shown in FIG.

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

As shown in FIG. 4, when the gas is used while checking the gas leakage, when the intermediate valve 20 is closed in FIG. 2 when the intermediate valve 20 is closed as shown in FIG. 3, the gas is connected to the piston 70. Gas flows toward the O-ring 1 (100) and O-ring 2 (101) is not flowing. Therefore, when the upper button 60 is pressed in the state in which the intermediate valve 20 is completely closed as shown in FIG. 4, the piston unit 70 is interlocked upward, and at this time, O-ring 1 (100) and O-ring 2 (101). , O-ring 3 (102), O-ring 4 (103) is also moved while the supply passageway 80 and the movement path 110 is connected, O-ring 4 (103) configured on the lower side also moves in conjunction with the piston (70) While opening the connecting passage 50 between the discharge passage 90 and the water tank 30, at this time, if the gas does not leak, the gas flowing through the gas supply port 40 does not flow to maintain the gas droplets do not occur However, if the gas leaks from the unknown portion, the gas introduced through the gas supply port 40 passes through the gas pipe 130 through the moving path 110 and passes through the water in the water tank 30, and the discharge passage ( While leaking through the 90, the water container (30) of the gas leaked through the gas pipe 130 As is the gas bubbles generated. By visually confirming this, gas leakage is confirmed.

Therefore, the button-type gas leak check valve of the present invention configured as described above simplifies the complex structure of the conventional button-type gas leak check valve of FIG. 1 to increase the precision of operation and performance, reduce the weight, and reduce the value as a product by miniaturizing the appearance and appearance. It is designed to increase the processing speed and increase the production speed during mass production.
