Gas cylinder structure for car

This creation department relates to the structure of a gas cylinder for a vehicle, especially a composition of a gas cylinder for a vehicle having the strength of a chain structure and maintaining the safety of a high degree of tightness and airtightness.

According to recent years, due to environmental protection and economic factors, gas (liquefied petroleum gas) is used as a fuel for vehicles. It has superior characteristics such as complete combustion than gasoline and lower pollution emissions than gasoline. Therefore, it is in Japan, the United States, Australia, South Korea, Italy. Countries such as the Netherlands and the Netherlands have already adopted gas vehicles for energy. It is precisely because of this that the gas vehicles that were originally illegally modified in China have now become the government’s initiative to replace millions of gasoline with gas to supply millions. The car of the meter, further, plans to add a gas station, and subsidized the modification, in order to achieve the purpose of universalization of gas vehicles, because the gas on the road is extremely easy to explode, so the safety of the gas car is also Consider carefully.

It is reported that vehicles modified to use LPG (liquefied petroleum gas) are commonly known as gas vehicles. Dual-fuel gas vehicles refer to the use of "gasoline fuel" or "LPG fuel". The so-called gas vehicles on the market, All are dual fuel systems that can be switched to each other. The main thing of the gas car is that the LPG cylinder must be several times stronger than the gasoline "tank" and resistant to impact (the thickness of the LPG steel plate is 3mm, the thickness of the main beam of the car is 1.1mm), and the LPG high-pressure cylinder has two horizontal and vertical positions. The type depends on the size of the installation space. Generally, the installation of LPG cylinders does not affect the trunk space, so it is more horizontal.

LPG high-pressure steel cylinder is mainly composed of several pieces of metal substrate corresponding to welding. Then, the filling valve, output valve, safety valve, liquid level indicator and other components are installed on the cylinder. The steel cylinder is designed with various safety valve parts to make the cylinder automatic. The gas filling capacity is 80%. With a pressure of 30kg/cm2 or more, it is very durable and is a product that has passed the test and certification. The safety design of the product is also higher than that of the vehicle fuel tank. Therefore, the yield of the cylinder is related to the safety of the gas vehicle. It is one of the first concerns raised by the public. However, since only the welded external joints are used in the production of the steel cylinders, it is difficult to control the quality due to the welding technique, and the problems of the thickness, the adhesion and the use time of the solder joints cannot be effectively controlled, and the gas is easily deflated; therefore, This is one of the problems that the industry has to actively research and develop to overcome.
