Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0013] Such as figure 1 with figure 2 A pressure test sealing tool for LNG gas cylinders for vehicles is shown, which includes a support tube 11 arranged at the end of the LNG gas cylinder, and a gas cylinder dispensing head 5 installed at the head of the support tube 11 . The gas cylinder distribution head 5 is provided with an upper sealing cover 4, the bottom surface of the upper sealing cover 4 extends downwards to form an annular baffle 13, the inner wall of the annular baffle 13 is close to the gas cylinder distribution head 5 and Its end is no more than the bottom surface of gas cylinder distribution head 5. The outer side of the annular baffle 13 and the gas cylinder distribution head 5 is provided with a lower sealing cover 6 , and the bottom of the lower sealing cover 6 is provided with a connecting plate 7 for clipping the lower sealing cover 6 .

Abstract

The invention relates to a pressure testing seal fixture of an automobile LNG (Liquefied Natural Gas) cylinder. The pressure testing seal fixture comprises a support pipe at the end part of the LNG cylinder, and a cylinder distributing head at the head part of the support pipe, wherein an upper sealing cover is arranged on the cylinder distributing head, the bottom surface of the upper sealing cover downwards extends to form an annular baffle plate, a lower sealing cover is arranged outside the annular baffle plate and the cylinder distributing head, a connecting plate is arranged at the bottom of the lower sealing cover, a gas hole is formed in the cylinder distributing head and communicated with a gas pipe on the cylinder, a gas cavity is formed between the cylinder distributing head and the bottom surface of the upper sealing cover, and a limit pipe is arranged at the center of the top of the upper sealing cover and is communicated with the gas cavity. The pressure testing seal fixture has the beneficial effects of simple structure and convenience in operation; when the pressure testing seal fixture is applied to tests on cylinders with different sizes, the sizes of the upper sealing cover, the lower sealing cover and an O-shaped sealing ring only need to be changed.

Description

technical field [0001] The invention relates to the field of manufacturing LNG gas cylinders, in particular to a pressure test sealing tool for LNG gas cylinders for vehicles. Background technique [0002] With the rapid development of modern economy and technology, LNG (liquefied natural gas liquefied natural gas), as a new type of energy, is developing very rapidly. As the gas cylinder industry carrying LNG is also showing a rapid upward trend, the safety of gas cylinders is getting more and more attention. As an important process in the production process of LNG cylinders, the pressure test is used to test the bearing pressure of the cylinder itself, which plays a vital role in the performance of the product. The existing pressure test sealing technology uses simple rubber pads and carbon steel fixing rings to cover the holes around the distribution head. The rubber pads are prone to aging after long-term use, and the sealing performance is not good, posing safety hazard...
