[0001] VALVE ASSEMBLY FOR INTERFERENCE GAS [0002]

The present invention relates to a gas shutoff valve assembly that is installed in a gas pipeline and is configured to automatically shut off the gas when a predetermined time elapses. In particular, the valve is firmly coupled to the main body to provide an excellent product stability and durability, So that malfunctions are prevented.

Most households and businesses use a variety of fuels for heating and cooking, mostly gas fuels such as LPG (Liquefied Petroleum Gas) and LNG (Liquefied Natural Gas). In the case of LPG, it is supplied to consumers through special containers with excellent pressure resistance. In the case of LNG, it is generally supplied to the customer through the city gas pipeline.

The piping for supplying the gaseous fuel is divided into an outdoor piping for distributing the gas fuel from the building to each home or business and supplying the gas to the room, and an indoor piping for supplying the gas supplied through the outdoor piping to a gas stove or a boiler And a gas shutoff valve is installed in the indoor pipe to shut off the supply of the gaseous fuel.

The gas shut-off valve is in the form of an on-off valve for allowing or blocking the supply of the gaseous fuel, and is opened or closed by a direct operation of the user.

Therefore, the user confirms the opening / closing state of the gas shut-off valve in consideration of the use of the gas stove or the boiler, and when the gas is not used, the gas shut-off valve is operated to shut off the gas supply.

However, the above-mentioned conventional manual gas shutoff valve has to take the trouble of confirming the open / close state directly by the user, and if the check operation is overlooked, a safety accident due to gas leakage may occur.

Accordingly, recently, an automatic gas shutoff valve has been developed which automatically cuts off the supply of gas after a predetermined time elapses. These automatic gas shutoff valves are designed to automatically shut off the valves using mechanical timers with spring and multiple gears. However, the structure of the timers is complicated and the volume is large, which can cause interference with the wall where the valves are installed, There is a possibility of occurrence.

Accordingly, the present invention has been developed and applied to a gas-blocking valve assembly that cuts off the supply of gas through an electronically controlled timer instead of a mechanical timer. This is disclosed in Korean Utility Model Publication No. 20-2009-0008224 have.

The above-mentioned prior art design includes a valve having a pipe and a hose connection formed at both ends thereof, a valve provided with a knob for connecting and disconnecting gas to the stop, and a controller for setting an opening time of the valve, A power supply unit for outputting a constant voltage regardless of the power supply voltage; A driving unit electrically connected to the power supply unit; An input unit for inputting data for setting an opening time of the valve; An output unit for outputting an open / close state and an open time of the valve to the outside; And a control unit for controlling the operation of the driving unit according to the set opening time through the input unit.

Since the above-mentioned prior art design outputs a constant voltage from the power source irrespective of the input power source, it operates not only at a low voltage of less than 5V, but also has a simple power generation and transmission structure and a small volume, There is no interference with the wall at the time of installation, and there is an advantage that the shutoff operation of the gas is sure, so that it can be used safely.

However, the prior art design has a problem that when the valve and the case are combined with silicon, the valve is separated from the case when the valve is used for a long period of time, causing an error, and the fuse cock valve is formed of zinc.

In addition, when the button is brought into close contact with the front member, foreign matter is adhered to the front member, the button is not operated, and the restoring force of the lever spring is lost during long-term use.

Moreover, since the whole product is formed as an integral structure, the cost and the processing time are excessively increased due to the replacement of the entire product, and the voice guidance function is insufficient, thereby failing to satisfy the needs of the consumer.

On the other hand, as a result of investigation of prior art related to the present invention, a large number of patent documents were searched, and some of them were introduced as follows.

Patent Literature 1 discloses a power transmission device that includes an electric motor for opening and closing, a gear group for transmitting and decelerating the rotation of the motor, and a gear train for engaging and disengaging the gear train, And a control system for setting the time and counting the progress of the set time and driving the electric motor to close the valve when the set time has elapsed, wherein the closing drive is performed according to the lapse of time of the set timer And can be manually opened and closed in parallel with the electric opening and closing. In the non-operation state, the structure of the clutch releasing the coupling of the electric power transmission gear group is simplified, which is suitable for reduction in size and weight. A timer valve is described.

Patent Document 2 describes a gas safety device provided in a fuse cock provided in a general kitchen gas pipe to automatically shut off the gas when a predetermined time has elapsed so that unnecessary gas consumption can be suppressed and fire can be prevented .
