The helmet is an important accessory for the cylinder. It is worn on the cylinder valve of each cylinder to ensure that the valve is not mechanically damaged and safe.
Why do gas cylinders need to wear a helmet?
Because the cylinder valves of cylinders are mostly made of copper alloy, they are relatively fragile. Although some are made of steel, since the structure of the bottle valve is finer than that of the bottle body, it is screwed on the bottle body to form a right angle between the bottle neck and the bottle valve joint. It is both a brittle defect of the bottle body and a protruding point of the bottle body. Most susceptible to mechanical damage or external shocks. If during the process of transfer, storage and use, due to inadvertent damage, the cylinder falls, falls, rolls or is hit by other hard objects, it is easy to show that the valve joint and the bottleneck joint are cracked. The bottleneck or the cracking of the bottle valve, the high-pressure gas in the bottle is lost and manipulated, so that the high-pressure gas is ejected, and the reaction force causes the gas cylinder to rush in the opposite direction, which can damage the equipment and buildings, and even cause casualties. The gas ejected at high speed in the bottle will be determined by the nature of the gas in the cylinder to bring about more serious secondary accidents (such as fire, explosion, poisoning, etc.). If the bottle is filled with a combustible gas, static electricity generated by the intense friction of high-speed jet or other fire sources may cause combustion and blasting.
On the other hand: the bottle valve is exposed to the outside, and it is easy to invade dust or grease during transfer and storage, and then poses a risk.
In order to eliminate the above risks and avoid accidents, people put a cap on the gas cylinder because it is an important safety accessory. The gas cylinder is wearing a safety helmet, which not only protects the valve from impact, but also prevents the ingress of grease, dust and the like. Therefore, the bottle making unit is required to have a safety helmet when the steel is shipped from the factory. When using the gas, put the helmet down and put it in a fixed place. After use, put on the bottle cap in time and do not throw it.
