And these gas cylinders often store high-pressure gas inside. When the gas cylinder valve breaks due to an unexpected situation, the high-pressure gas in the gas cylinder is released instantly, which will cause the gas cylinder to run around and cause harm to the user and nearby personnel. , however, gas cylinder valves currently on the market lack this protection against accidental disconnection

At present, various gas cylinders are widely applied to various fields, such as air respirators in the fire-fighting field and oxygen cylinders in the medical field; high-pressure gas is stored in thegas cylinders, and when gas cylinder valves are broken under an unexpected condition, the gas in the gas cylinders is released instantly, the gas cylinders move all around, and consequentially, usersand personnel nearby are injured. However, the gas cylinder valves on the existing market do not have a protection function to handle accidental breakage. According to a novel safety gas cylinder valve, high-pressure gas in a gas cylinder can be gradually released via a gap generated when a chamfer abuts against a circular truncated cone, so that the safety gas cylinder valve has high safety performance, potential safety hazards of the gas cylinder valve are eliminated, and the safety of users and personnel around is ensured; and meanwhile, a barrier pipe is arranged so that a limiting valvecan be firmly positioned in a main body, and the structural stability is improved.
Description
technical field [0001] The invention relates to a novel safety gas cylinder valve. Background technique [0002] At present, various gas cylinders are widely used in various fields, such as air respirators in the field of firefighting, oxygen cylinders in the medical field, and so on. And these gas cylinders often store high-pressure gas inside. When the gas cylinder valve breaks due to an unexpected situation, the high-pressure gas in the gas cylinder will be released instantly, which will cause the gas cylinder to run around and cause harm to the user and nearby personnel. However, gas cylinder valves currently on the market lack this protection function after accidental disconnection. Contents of the invention [0003] The purpose of the present invention is to provide a new type of safety gas cylinder valve, including a valve body, the lower end of the valve body is provided with a current limiting protector, and the current limiting protector includes a main body, a ...
