Description

Pressure Vessel System Inspection System for Gas Vehicles {EQUIPMENT FOR INSPECTING PRESSURE RESISTANT CONTAINER SYSTEM OF GAS VEHICLE}

The present invention relates to a pressure vessel system inspection system for a gas vehicle for inspecting and inspecting a pressure vessel system for storing and supplying fuel gas installed in a gas vehicle such as a CNG bus. The present invention relates to a pressure vessel container system inspection facility for a gas vehicle, which enables inspection and inspection of the pressure vessel container system to be carried out more conveniently in a vehicle mounted state, and enhances workability and efficiency for inspection of the vessel. .

In general, the vehicle fuel can be compressed natural gas (hereinafter referred to as "CNG"), LPG, hydrogen gas, etc., these gases are compressed to high pressure to facilitate storage, transportation and management It is used.

Among these, methane-based CNG is a natural gas, and is widely used as a fuel for vehicles by replacing gasoline and diesel as needed for de-petrolization or air pollution improvement.It is mainly installed in a bus, but accommodated in a pressure vessel. It is attached.

However, CNG has a risk of explosion because gas is compressed at high pressure in a pressure vessel, and there is a risk of explosion, especially when the temperature is high, such as summer, the safety of the pressure vessel becomes weaker and the gas leaks from the pressure vessel. Since it explodes when contacted with a flammable material has a problem that is directly connected to a human accident.

Accordingly, the pressure vessel system that is mounted on the gas vehicle, such as the pressure vessel, the fuel device and other mounting system connected thereto, is urgently required to secure safety, and therefore, the safety of the pressure vessel system is regularly checked according to the operation of the vehicle. In addition, maintenance work is being carried out, such as replacing or destroying the pressure vessel.

On the other hand, the applicant of the present application intends to propose an inspection facility for providing the ease and efficiency of the inspection of the pressure-resistant container system mounted on the upper or lower portion of the vehicle in a gas vehicle such as CNG mounted on a vehicle such as a bus However, the prior art regarding the pressure vessel system inspection equipment of such a gas vehicle is not easily found.

In addition, in relation to the pressure vessel of the vehicle, Korean Patent Publication No. 10-2012-0082984 discloses "vehicle pressure vessel gas for detecting the early leakage of gas even when a small amount of gas leak to prevent gas leakage and explosion accidents Leak detection device technology and domestic Patent No. 10-1069897 in the "Registration of high pressure vessels filled with compressed natural gas or hydrogen gas, such as pressurizing a certain pressure in the state and leakage of high pressure vessels at high pressure Internal pressure inspection and inspection gas of vehicle high-pressure container for vehicle fuel filling to prevent serious accidents such as leakage, deformation or explosion of high-pressure container in advance, and to collect and reuse the inspection gas repeatedly for inspection. Recovery apparatus and method "has been proposed, but will be strictly distinguished from the applicant's technology proposed below .

The present invention is to create a technology for the inspection equipment of the gas vehicle pressure vessel system that is not in the field, it is more convenient to perform the inspection and inspection of the pressure vessel system mounted on the upper or lower portion of the gas vehicle in the vehicle mounted state The purpose is to provide a pressure vessel system inspection system for a gas vehicle.
