Abstract

The invention relates to the technical field of safety protection, in particular to a joint of an air supply valve of an air breathing apparatus.The joint comprises a joint body, a lower valve rack, adamping assembly and a grizzly. The joint body is of a hollow structure, two ends of which penetrate; the lower valve rack is fixed to the lower end of the joint body; the lower valve rack is of a hollow structure, two ends of which penetrate; the lower valve rack communicates to the joint body; the grizzly is fixed below the lower valve rack on the inner side of the joint body; a plurality of through holes for oxygen circulation are formed in the grizzly; and the damping assembly is fixed between the lower valve rack on the inner side of the joint body and the grizzly. According to the air supply valve of the air breathing apparatus provided by the invention, noise is reduced obviously by means of mild damping action of the damping assembly and the grizzly to a breathing air flow, so that a good noise-reducing effect is achieved. The air demand is great and the joint is simple and convenient to debug.

Description

technical field [0001] The invention relates to the technical field of safety protection, in particular to an air supply valve joint of an air respirator. Background technique [0002] The air respirator is a kind of respiratory protector that is completely isolated from the outside atmosphere, and is widely used in high-rise buildings, chemical units, military facilities, underground engineering and mines and other fields. When harmful gases are generated due to fire, poisonous gas leakage, gas explosion, etc., the on-site personnel use air respirators to protect their own respiratory systems. During the use of the air respirator, the respiratory system is isolated from the outside world, and the instrument forms an internal circulation with the human respiratory system, and the air is supplied by a high-pressure cylinder. The air supply valve joint of the existing air respirator is composed of a valve body and a hood installed inside it. During use, the noise generated is...
