Description

A gas valve for vehicle

The present invention relates to a gas valve, and more particularly to a gas valve used in a gas container for a vehicle.

Recently, vehicle fuel is being replaced by LP gas from gasoline or diesel due to an increase in the price of gasoline, which is a vehicle fuel, and environmental pollution due to an increase in vehicles using gasoline or diesel.

Gas valves used in LP gas containers for vehicles are disclosed in Patent Publication No. 95-9981 (hereinafter referred to as a crew), but have a disadvantage in that their internal structure is complicated to make and is likely to fail. In addition to the valve device of the source, there are other types of gas valves for vehicles, but all have a disadvantage in that a relatively large space is required for the gas valve installation because the distance between the handle part and the gas inlet part is far. In particular, the LP gas container is installed in a state of lying on the side of the trunk of the vehicle, the gap between the side wall and the handle of the vehicle is narrowed, which is inconvenient to open and close the valve.

The purpose of the present invention is not only to reduce the gas leakage, but also to reduce the space between the gas inlet portion and the handle in the LP gas container of the vehicle by the simple structure and to save the side space according to the gas valve installation An object of the present invention is to provide a gas valve for a vehicle that is convenient for a user to operate.

The body 105 is a portion that provides a gas exhaust passage and the space for installing the necessary parts. As shown in the body 105, the first coupling portion 110 is formed. The first coupling portion 110 is a portion which is coupled to the gas container, and may be configured by forming a spiral 112 on the outer circumferential surface thereof. The first coupling portion 110 is a portion disposed in the longitudinal direction of the gas container in the installed state, the first hollow portion 114 that provides a discharge passage of the gas is formed therein.

Body 105 has a second coupling portion 120 is formed. The second coupling part 120 is a portion which is connected to the fuel system of the vehicle and is disposed in a direction substantially perpendicular to the first coupling part 110, and is preferably formed by forming a spiral 122 on an outer circumferential surface thereof. Do. Inside the second coupling portion 120, a second hollow portion 124 communicating with the first hollow portion 114 is formed. The second hollow portion 124 also provides a gas discharge passage.

Body 105 has a third coupling portion 130 is formed. The third coupling part 130 is disposed perpendicular to the first coupling part 110. The third hollow portion 134 perpendicular to the first hollow portion 114 is formed inside the third coupling portion 130. The third coupling portion 130 is to be able to install accessories necessary for opening and closing between the first hollow portion 114 and the second hollow portion 124, it is formed by forming a spiral 132 on the inner peripheral surface near the upper end It is desirable to. The third coupling portion 130 is perpendicular to the first coupling portion 110 and the second coupling portion 120, that is, installed upward in the state mounted on the gas container in the vehicle, the gas is introduced from the gas cylinder It serves to reduce the horizontal distance between the handle 140 is installed on the portion and the third coupling portion.
